The article reviews the potential of using insects as a food source to complement the traditional food production in order to meet the needs of the increasing world population.
The nutritional quality of insects is high. They are a source of protein, fats, minerals (especially iron and zinc) and vitamins.
The production performance of insects out performs the one of traditional livestock, with a feed conversion ratio (number of kg of food to produce 1 kg of insect) ranging between 1 and 2.
There are already 1,400 species of insects consumed regularly in Africa, Asia and Latin America. Among the favourites, they name beetle larvae, ants, caterpillars, locusts, crickets, silkworm chrysalis, scorpions and spiders (although the two latter ones technically are not insects).
In most cases, insect consumption is the consequence of food shortage, but there is also a festive consumption of the bugs. The author mentions that in the old Roman Empire, caterpillars were a delicacy. Of course, in some Western countries, some restaurants offer insects at a premium price for a certain self-proclaimed sophisticated elite… After all, a lobster looks very much like a large aquatic bug.
Another interesting potential for insect is to use them as a raw material for fish feed. Currently, fish feed is made of increasingly expensive raw materials, such as fish meal, fish oil and agricultural commodities, for which they compete with human consumption, use for feed destined to other farm animals. For many fish species, insects are a natural source of food.
There are talks about organizing the first congress on insect as afood source as early as 2012.

The editing of my book “Future Harvests – The next agricultural revolution” is about completed. All that is left to do is developing the cover and start the publishing.
I have already received orders, even before the book is out. That is quite a good sign. And a great surprise for me.
If you wish to be updated automatically when the book is published, just subscribe in the sidebar window on the right.
To describe the topics addressed, I have posted three short promotional videos on YouTube. In previous articles (The fun of writing this book and The next agricultural revolution), I had already given an idea about the content of the book.
Video #1: The Fundamentals (duration 2:37) – Introduction to the background and fundamental principles mentioned in the book “Future Harvests – The next agricultural revolution” to achieve food security for 9 billion people in 2050. Topics such as demographics, the shift in economic power, the control of food and food security strategies are reviewed. Sustainability, innovation, efficient market driven food production and strong leadership are required.

Over the last few months, I have been working quite a bit on writing this book about the future of agriculture.
I must say that compiling in one book a wide range of topics that, without any doubt, will be part of the future of our food production has been an exhilarating experience.
From demographics in full motion to the latest in technology, we can envision many different scenarios to set up the most efficient food production possible, as local farmers, industry NGOs and governments will need to find optimal solutions with the land, the water, the labor force and the capital available to them. Water and soil will be of vital importance, and their proper management is essential for the stability of many countries.
In the future, there will be no room left for wastage and inefficiencies, or we all will be punished if we get complacent. Similarly, we will need to change our thinking and accept that solving future problems will not be about transferring a one-fit-all model to very diverse situations. We might have had the illusion that it once worked, but it actually did not. We will learn from the mistake of the past to perform better. Sustainability is not an option; it is the only choice, because per definition what is not sustainable is doomed.
As food is a necessity, and since when we share between 9 billion people there is less left for each of us than when we shared between 4 billion, efficiency will be paramount. This will affect food prices and social stability. Technology is necessary but it is not the panacea in itself. The most needed resource for the future is strong visionary leadership to help us develop the plan for the next decades.
Let’s prepare ourselves for a deep change and we must accept the idea that we might have futuristic farms run by robots, satellites and computers in some regions as well as local urban gardeners in the heart of the cities, where 70% of the world population is expected to live. We will have small organic farmers and we will have large industrial farms using genetically engineered crops, but we also will have large highly efficient semi-organic farms that will combine the best of both worlds. We still will have specialized farms as well as mixed operations. Hydroponics and aquaponics will grow substantially in the future.
Today’s diet will be revisited and excesses will be out of place. Should we become vegetarians or do we simply need to eat less meat? Will aquaculture live up to the expectation and become the main source of animal protein? You will find out in the book.
Countries will have to think on how to guarantee food security to their populations. If it is not done well, this challenging task might end up in serious conflicts. Foreign and private investment in land and farming will continue in Asia and Africa. If managed properly, they will bring much prosperity to these regions, but if not managed properly, then we can fear the worst.
All these topics and many more will be presented in the book and I hope that it will help readers to understand all the variables that are at play, as well as it will help them get a more objective view of many controversial topics such as GMOs, nanotechnology or in-vitro meat. Once readers will have finished the book, they will be able to figure out whether and how we can feed 9 billion people. Thanks to examples from all over the world in as diverse countries as Uganda, Kenya, the USA, China, Indonesia, India, Brazil, Argentina, France, The Netherlands, Cuba, Kazakhstan and many more, we discover a myriad of different situations and solutions that illustrate human ingenuity to produce food.
However, for now just a few more months of patience as I need to get through the process of publishing.

Last week, BioScience published an article based on the research of a group of researchers from the CSIC (Consejo Superior de Investigaciones Científicas), the Spanish High Council for Scientific Research.
They present their views on the potential of marine aquaculture to provide enough food for the growing world population. The authors of the report do not see fisheries as a significant option anymore, as the wild fish stocks are depleted, and the amount of time to replenish the stocks will be too long for fisheries to be able to meet the needs of the population. Aquaculture has gradually compensated the demand for fish that fisheries were not able to supply, and half of the seafood consumed today already originate from aquaculture. It is the fastest growing food supply activity and the projections for future growth are very strong. The researchers think that marine aquaculture could multiply its production by a factor 20 by 2050 and thus would play a major role in providing the world population with animal protein.
They bring up some interesting facts about agriculture and land animal farming. For instance, it takes 10 times more water per calorie to produce meat than it does to produce grains. Further, animal meat products represent only 3.5% of food production, but they consume 45% of the water used in agriculture. Considering demand for meat is expected to increase by 21% between 2005 and 2015, and will keep on increasing, this will only exacerbate this situation.
Another point that this group raises is the global nitrogen-use efficiency in animal productions. According to their sources, it is slightly more than 10% for land animals (5% for beef and 15% for pork), which makes their production a major source of nitrogen inputs to the environment. In contrast, marine animals have much greater nitrogen-use efficiency, at about 20% for shrimp and 30% for fish. Therefore, marine aquaculture culture releases two to three times less nitrogen to the environment than livestock production does.
From an environmental point of view, the idea of shifting the production of animal protein from the land where it uses scarce resources such as land and water, to the ocean where space and water are no limitations anymore sounds very sensible. From a nutritional point of view, replacing meat and dairy by seafood that is rich in healthy components such as omega-3 fatty acids is quite attractive, too.
They also notice that the land available for agriculture is shrinking, due to soil degradation and urbanism. Further, there is a growing scarcity of fresh water and increased competition for water as well. Therefore, activities on land do not offer the potential to grow all that much more food to feed the growing population. Even freshwater aquaculture faces these limitations. Freshwater aquaculture currently 57% of total aquaculture, therefore there is an untapped potential with marine aquaculture, as it does not use fresh water.
Of course, the main challenge to execute such a development of marine aquaculture production is to find the proper quality and quantity of feed. The researchers do not see the use of fishmeal and fish oil as an option anymore as they predict that the species used to make these products will not be able in sufficient quantities. Replacement by protein and oils from agriculture crops is an option for the short-term, but as aquaculture volumes would increase, the competition for these ingredients with meat production will make them too expensive, and for the reasons explained above, depending on land agriculture to feed marine species will face crop production limitations. Therefore, they prefer to envision a total new approach of aquaculture feeds, and recommend developing a new feed chain based on aquatic ingredients, such planktons, microalgae and seaweed. This approach makes sense, but the time lines to develop such a supply source and the cost of production of such an “aquatic” feed still need to be investigated. Several “seaweed farms” in production in China show interesting results and they seem to promise a strong potential of production for feed.
Another development that they expect is offshore aquaculture. Aquaculture operations located in coastal areas, although they are easier to access and generally in quieter waters, are very often located in zones where there are local issues to deal with, such as interaction with wild fish or recreational activities. Moving offshore can reduce these issues.
As you can see, developing the future of aquaculture is not simply a matter of growing fish in pens, but it requires a broader thinking that includes not only the oceans but agriculture on land, too. The future of food will require from us the ability to manage the whole planet!

Here is a think-out-of-the-box article about the “vertical farm”.
It is an interesting vision of a replacement of agricultural land, by indoor robot-tended hydroponic agriculture. They also envision the possibility of raising farm animals and developing aquaculture in the water used to grow the plants; and the fish waste would be used as fertilizer.
All of this would be grown in a 30-floor skyscraper located in the city, powered by the energy coming from city sewage, and the ground floor would be a food supermarket that would provide food for 50,000 people.
Such projects are under review in Abu Dhabi, South Korea, Seattle, WA and Las Vegas, NV.
It looks like science-fiction, yet there are some really interesting arguments in favor of such a development.

Food strategies around the world
In this article, the term hot does not refer to climate, but to strategic and active food producing regions. Not only is the population growing, but also the demographics vary greatly between regions and this will change deeply where from and where to the trade is going. Here are, briefly, the main changes as I see them happening as we go forward.
The aging and increasingly health-conscious West will not show any increase in consumption per capita, and very likely it even will drop, as older people need less food than the youth and also because the shift from quantity to quality will continue. Of course, immigration policies in these countries might offset this somehow. The direct consequence of this is that suppliers are going to have to look for alternative markets for agricultural products. They should not have to worry too much, as there will be plenty of people to feed in other regions.
Asia, with about half of the world population is definitely a huge market, although it presents a great variety of conditions and situations.
The largest economy in the region, China, is developing a middle class with more disposable income. This results in a change of diet, with relatively more protein, especially animal protein than by the past. Although being the largest meat producing country in the world, China is struggling to feed its population, and I expect that it will remain a net food importer. Further, the country has major challenges to overcome when it comes to availability and quality of water. However, in the long run, the past one-child policy will affect the Chinese demographics and influence their need for food, as well as the dynamism of their economy at large, by the way.
The second largest economy, India, is very dependent on the monsoon for its food supplies, and climate will remain a challenge. They seem to struggle to be able to secure their self-sufficiency, rural development is still a challenge and poverty remains a concern to reach prosperity.
Emerging South Asian countries, on the other hand, for instance Vietnam, show a different picture. They have a young population and want to benefit of the economic momentum coming from China. They are actively developing agricultural and aquaculture production for export purposes, and they keep on this policy. Aquaculture is very active, as some of these countries have a very extensive shoreline, like for instance The Philippines.
Although food security in the region remains uncertain, and the scare of last year’s food price increase, some countries are trying to establish structures to protect from such risks. For instance, a number of ASEAN countries are trying to set up a rice cartel, some sort of an OPEC for rice, in order to have more control on the market and the prices. Of course, we will have to see if this will work as planned.
Another region that is showing booming demographics is the Arab world and the Middle East. Many countries in the region are wealthy thanks to oil, but also have the disadvantage to be located in desert areas. Attempts to increase food production have met their limits, and they do not guarantee food security. The main reason is the shortage of water and trying to grow more food would create a drinking water crisis. This is why some Arab countries are developing other strategies to “outsource” their food production like mentioned in the article “The Great Unseen Land Grab”. Other countries, like Qatar, are considering investing in food companies in order to secure their food supplies.
Some players are already making their moves
I expect stronger ties between the Middle East and former soviet republics. Russia, Ukraine and Kazakhstan are joining forces in the “Black Sea Wheat Pool”, another agricultural OPEC. Although we will see how this combination works. Another area that I see booming in the future is the Mediterranean region, which is the interface between Africa and Europe. Although immigration has been a hot issue in the past, there is a great potential for a win-win situation for both sides if managed properly. The idea of creating an Economic Zone around the Mediterranean has already been brought forward and considering the demographics of the region, it makes quite a lot of sense.
Africa, although plagued by many problems, be it natural, social, political, humanitarian or health, as a huge untapped potential. The plans of Arab and Asian countries to lease land on this continent and develop agriculture for their needs, could give the necessary impulse to develop African economies. I also believe that South Africa has the potential to be the driver of the economic surge for the continent.
Last but not least. South America and Brazil in particular, is going to play a major role in agricultural production. They have an amazing potential, but also many issues to solve, especially on the environmental and political level. Their position of producers of basic commodities as well as high value products like meat gives them a strategic role in the international food trade, and the upcoming merger between JBS and Pilgrim’s Pride in the US and between JBS and Bertin is another step in the creation of agribusiness giants, following the merger between Perdigao and Sadia.

Although the title of this article many sound a contradiction in terms, agriculture (in which I include aquaculture as well) needs cities and vice-versa. Rural development is more than just agricultural activities; it is about creating and improving a cluster of many economic activities that are necessary for the proper functioning of a community.
As such, this should not be a surprise, because in the history of man, human settlements always have been linked to drinking water and sufficient food supplies. By developing agriculture, the very first “farmers” created the conditions for sedentarism, instead of continuous migrations. On these sedentary communities, other activities developed later to cover the needs of the locals. 
The hierarchy of the needs that we must fill can be easily identified according to the pyramid of Maslow: food and water, shelter and physical safety. Once this is achieved, adding other activities become more natural and simple.
This is why developing large urban centers is no guarantee of prosperity. Like all things in life, the key is about balance. Of course, over the last 150 years, the focus has been about growing the industrial capabilities and this has been the engine for a massive migration of population from the countryside to the cities. Although the conditions were far from stellar, many companies in the early industrial development were providing their employees with housing. Their ways may not always have been very social, but they were showing some level of social responsibility.
With the ups and downs of industries, cities have increasingly faced a problem of poverty, as the development did not include a sense of community anymore and company loyalty towards their employees disappeared as the workforce became expendable and factories could move to other countries.
This industrialization and urbanization have also affected the rural areas and the agricultural world. Many rural areas have faced and are still facing isolation and poverty. Although in many cases there have been many efforts made to improve this situation, the situation has not always improved.
Yet, we now see the challenges of feeding an ever-increasing population, we all recognize that we will need to cultivate more land and water, but this still does not seem to make things turn around.
In my view, the problem is that, too often, we restrict rural development to agricultural development, and by looking at this part in a separate way, instead of focusing on integrating agriculture in the development of the whole local economy, we just do not create strong enough chances of success. Having large urban centers with their problems on the one hand, and remote and depopulated rural areas with their problems on the other hand, should be the clear sign for all of us that our economic model is out of balance. There can be life outside a huge metropolis where everyone has become an anonymous person, resulting is a dislocated social fabric. What has made the success of our species has been our ability to act as groups. As isolated creatures, we probably would not have survived very long.
To rebuild the necessary social fabric in rural areas, we must create the conditions to have balanced and complementary activities. This is why, while some see the future of agriculture as urban farming, I believe that it has to be urbanizing the countryside, not with large impersonal cities, but with human size settlements where we can provide for all the needs. Isolated farmers with no direct connection with their markets and not getting the value for their products to make a decent living will look for alternatives. If we want more people to produce food, we must understand that they must make enough money to want to keep producing food. By creating a proper infrastructure around agricultural areas, we can create a more local market that will drive production. A profitable market for the farmers’ products also means more money in their pockets, which in turn means more spending power to develop demand for other business, be it for products or services. This is how we will be able to grow local economies and communities. This is not about a romantic or idealistic back to nature movement, or creating local farmers markets purely for marketing purposes, but this is a thorough and integrated process embracing modernity. In the current rural areas and probably in other regions, the future will about bringing the economy to the people before bringing people to the economy.

Health concerns will gain more importance in the future in the decision process of consumers when they buy their food.
More and more, we can hear and read about concerns and even rejection of the current production systems. Although this bad publicity is not always based on the most objective facts, it has been able to find a growing audience.
It must be true, it was in the newspaper
Since most consumers have little or no knowledge of agriculture and food, their only source of information is in the popular media. On the other side of the discussion, the agri-food industry is not getting through, because its message tends to be too defensive and too technical. Unfortunately for the industry, errors from the past (for example, the use of DDT) or cases from other industries (for example, tobacco) contribute to cast a shadow on its credibility. As I wrote my previous article “Less controversy thanks to transparency”, the agribusiness will achieve much more by opening up and having consumers visit their premises so that they can tell what they saw. They must organize more Open House days.
Therefore, for now, consumers have a certain perception of how food is produced, and it is not so relevant to argue whether this perception is correct or not. Perception simply is reality, and consumers act according to what they believe is true.
There is a growing concern about environmental and health aspects of food production. About the environment, you can list very diverse things such as the depletion of wild fish stocks in the oceans, the interaction between aquaculture and wild fish stocks, manure and smell of intensive animal husbandry and impact of manure on soils and drinking water, deforestation of rainforest for ranching of beef or about growing GMOs (Genetically Modified Organisms). On the health side, consumers worry about food poisoning due to bacteria, such as E. Coli, listeria, campylobacter and salmonella, but also about residues of pesticides or antibiotics, as well as they worry about the use of hormones in animal productions. As the discussions get more animated in the US about the reform of health care and the cost of obesity, more and more people are wondering about whether the fast food diet is a proper one. Next to this, animal welfare is a growing concern by more and more consumers.
The answer to many of these worries has started to appear in the last few years with the growth of the organic market segment. When we see the growth and the performance of a retailer such as Whole Foods, there is no doubt that organic foods have a growing audience.
The concerns about the environment are forcing retailers, food service and businesses involved in the production chain of food to make changes. Some of the actions they have taken can be seen as marketing or PR, but they also have become mainstream. Just a look at how many restaurant and supermarket chains have already implemented sustainable seafood programs indicates how serious this change in consumer attitude is. Fast food chains are also actively working on reducing their environmental impact and set standards on where they source their meat, based on environmental concerns, such as no beef from ranches deforesting the Brazilian rainforest.
In the past, we have seen some examples of production methods that had to be abandoned, simply because no solution to cope with environmental problems could be found. This has been the case in The Netherlands where the level of intensification caused such manure surpluses and risks of animal disease to such a point that after many years of looking for viable technical solutions in vain, the government decided that the size of the national herds had to be reduced.
Similarly to what happened in Europe over the last decade, we can expect that much stricter rules in the use of antibiotics will be applied, and I expect a similar trend to a progressive elimination of the use of hormones in animal husbandry. About animal welfare, there should not be any surprise the day that only husbandry systems that allow enough “recreation” area for animals will be allowed. All of the above is going to have an impact on how and where food is produced. Systems will become less intensive, and progressively we will see more techniques to improve efficiency to compensate.
Past Food?
As I also had mentioned in another article (Future price of fish and meat: up), it is simple logic that with more people to feed, food is going to become more expensive. However, the relative prices of various food products also need to go along their relative health benefits. Today, it looks like only wealthy people can afford a healthy diet, as the price of “good” food is substantially higher than the price of what makes a nutritionally unbalanced meal. This clearly does not work in the direction of a healthier population at large.
The way consumers think will define the way we eat and produce our food. Many changes in consumption patterns, in production systems and in product offering are under way. I will get back later with more details on what my views are on this.

We all have heard about this rule across all industries, including agriculture and food. Eighty percent of the food would be produced on 20% of the farms and vice-versa. If it still applies in the future, it can indicate us how our food production and supplies will look like in the future. Of course, this is always a theoretical exercise, but it is quite convenient to elaborate on our thoughts.
As the population is expected to grow quite strongly in the coming decades, especially in urban areas, this could indicate two dominant trends:
• Further size increase of the largest farms and further industrialization of agriculture and food for global markets, although the number of farms in this segment would not increase strongly.
• Strong increase of the number of small farms involved in specific value chains and strongly linked with their local economy.
Industrial agriculture
This group will continue to be involved in mass production of commodities for global supplies, like this is the case today.
Yet, they will face an increased pressure to adapt to the requirements of sustainability, which technically is quite possible. New systems and more efficient technologies will be the pillars of its growth and development. They will have to find ways of reducing the amount of chemicals in crops and the amount of pharmaceuticals in animal productions
The requirements for capital will be quite high and the sector will be led by increasing larger corporations, by an increasing level of capital by large private investors and, last but not least, by some governments. This agriculture will innovate further and will be developed thanks to this capital. It will use automation and mechanization to reduce the dependence on labor. Mergers & acquisitions will continue in the agricultural sector and a few large blocks will remain, dominating their sectors.
Their mandate will be about more control the natural conditions of production and about reducing to a minimum their impact on air, water and soil, by using less polluting transport methods, water preservation, effluent treatment and soil preservation. They also will have to engage in maintenance of their environment.
The role of this type of agriculture will be to bring to market large amounts of affordable food for the masses, and should play an important role in strategies around food security, which is where corporations and government will interact on a regular basis.
Local food value chains
This sector should undergo a strong growth and be build in a market-driven approach. These are the farmers that produce specialty products aimed at serving either a very specific segment of the retail or foodservice market.
This trend, which has been already initiated around concepts such as organic or authentic, will evolve into a more integrated local economy, and the initial concepts will probably become less differentiated as food production in general, be it industrial or traditional, will use more sustainable techniques.
Contrarily to the common belief, this agriculture will be developed thanks to very efficient techniques, but will be centered relatively more about labor and relatively less about capital. In this case, efficiency does not necessarily mean intensification.
We must not underestimate the significance of this part of the food production, as it will play an important role. However, we must not expect this type of agriculture to be the solution to feed the world, and this is not the purpose of the farmers involved in such food production chains.
This type of farming will grow in two different environments:
In emerging countries, the development of a local agriculture, and aquaculture, will be a key driver of economic development for under industrialized and/or under urbanized regions. It also will be a way of slowing down the migration of population to urban centers and limit social problems, by creating satisfying economic conditions and by securing food supplies locally. This farming will be about basic needs, before marketing.Copyright 2009 The Happy Future Group Consulting Ltd.

Here is an article from fis.com about another type of high tech fish farm with some nice futuristic design.
Hawaii Oceanic Technology Inc. has created the Oceansphere. “These elegant, self-sustaining and untethered semi-submerged floating pods are a revolution in open ocean aquaculture technology”, according to the fis.com article. The system is operated without the use of fossil fuels, which makes it environmentally quite acceptable.
As mentioned in the article, the company’s “plan is to demonstrate the feasibility of this technology and, as Jacques Cousteau said, farm the ocean as we farm the land.”

Here is an article of the National Geographic about “Giant Robotic Cages to Roam Seas as Future Fish Farms?”
This article addresses a number of very interesting and valid points, such as the possibility to move to better farming environment, or getting farms closer to consumer markets.
Having the ability to change location has several advantages. It allows finding areas where water quality is better as this varies with seasons and climate conditions. It also can allow farms to move away from the routes of wild fish and substantially reduce risks of disease and parasite contamination and spreading. Being closer to consumers market also has the advantage of reducing the amount of transportation and have the fish brought to market faster, therefore fresher, theoretically.
However, this article does not address a number of important aspects of fish farming. Going far offshore brings some organizational issues, such as rotating the crews working on farms, or dealing with rough weather. Probably some fine tuning would be needed to organize feed deliveries to such farms as well and the mobility must not happen at the expense of the life of equipment or the functioning of cameras and computers used for management purposes. As such, nothing that cannot be resolved, but it would come at a cost as well. Then it is to the farmers to weigh the pros and cons and make their decision.
Nonetheless, this is an interesting idea that shows that this industry is in full evolution and is adapting to the future.
Pioneering the oceans and robotizing aquaculture connects quite well with my previous articles “Innovation and tradition shape the future” and “The ocean, not Mars, is the next frontier“

In order to understand what changes are ahead of us, we need to realize that opposite forces are engaged in shaping the world of the future. As we all know, accepting change is always a slow and sometimes a difficult process. There are those who see the possibilities and those who see the drawbacks. The first train was going, supposedly, to get cows stop giving milk, but we now know that cows love to watch trains passing by. Probably, the first caveman who drew a picture of an animal on the wall was considered by some as a great magician and probably by others as pure evil. As such, such a struggle is very useful, as on the one hand it shakes immobility and open new doors, and on the other hand it prevents us to rush into the unknown without thinking first.
Change is part of our lives and that will not change. The problem that we face about change is actually about the pace of change, more than over the change itself. Over the last century, this pace has just increased steadily, thanks to more and more efficient technology.
If we look back the lifespan of the oldest living person, which brings us back to the end of the nineteenth century, just take a minute to think of all the changes that have occurred since then. There was no car industry, no antibiotics, no commercial airlines, no TV, no internet or cell phones, no supermarkets, just to mention a few things that we take for granted nowadays.
Although such a change is dramatic and has affected the way we live today, it has been a process that has needed time. Usually, it is said that more than 60% of the products that exist today did not exist 10 years ago and if we extrapolate this to decade to come, we can expect some even more spectacular changes.
Innovation is in constant motion and technology helps us to conceive and to use much faster than by the past. Yet, it is interesting to see that even with such a pace of change, traditions still play a very important part in our lives. Even with lots of modern gadgets, most cultures keep their specific characteristics. Their respective values do not evolve as much as our “things“, these just become part of the culture. This is an important point when it comes to innovation: what you offer must meet a need, if it does not, it will either fail, or at best be a fad.
Having a look at the future, you must wonder what the underlying trends of innovation are since it started. I can see several major constant areas of innovation:
What could this mean for food production in the years to come?
More technology to improve efficiency of water use, fertilizer use, animal feed use, land use, energy use (objective: zero waste).While such changes will come over time, consumers will still be looking for some level of tradition in foods. This can be about authenticity, regional specialties and recipes, or choosing to buy directly from farmers. Obviously, this is not a rational process, but it is more about the perception of “true” and “natural” production systems. After all, nostalgia is a constant of human emotions, too.

As everyone knows, fish stocks have been depleted to levels that are not acceptable. This is the result of short-term thinking combined with highly efficient but stupid fishing methods. Not only fish is a high value food source, but oceans are complex ecosystems that we cannot afford to lose. Although aquaculture claims to be the way to compensate the supply of wild fish, this is only true within limits, as some aquaculture species are fed with fish meal and fish oil, and replacement of these products is also limited by the quantities that agricultural crops can supply, and consequently their price.
As one of the points that I mention in my presentation “Twelve trends for the future of food production” (under Presentations tab), we can expect that programs will be set up to rebuild wild fish stocks and bring the volumes back to levels with which sustainable fishing methods and quotas will help provide us with more secure supplies. This will be some sort of a stimulus plan for seafood with all stakeholders involved: government, fishermen, aquaculture industry, retailers, food service and consumers.
A recent report published by the Pew Charitable Trusts has reviewed the possibilities and the economic impact of rebuilding fisheries in the Mid-Atlantic Ocean, as well as the downside of doing nothing. A Canadian research has worked in a similar direction and tend to show that rebuilding fish populations is possible, citing a number of successful cases (see article).
All that comes out from these reports is that the situation, although quite serious, is far from lost, but it requires political will and organization to make it happen. This is exactly why all parties involved from whichever country concerned will have to act in a coordinated manner.

With a world population increasing strongly and an agricultural area that will not grow accordingly, the law of offer and demand clearly indicates that agricultural prices will increase in the future. This is true for agricultural commodities such as grains, but the increase will be even stronger for animal products, such as meat, poultry, dairy and fish.
This will be the result of an increasing and very likely quite aggressive competition between the need to feed people with the basic commodities, the need to feed farmed animals and possibly for some time the need to produce biofuels.
Since it takes more than one and even several kilograms of animal feed to produce one kilogram of meat, the feed conversion ratio (FCR) will affect by which factor the price of the various animal products will increase.
Efficient productions like chicken will be successful and will remain quite competitive pricewise against other sources of animal proteins, thanks to its low FCR, to its low water use and to the good agricultural value of its manure. In the aquaculture sector, efficient productions such us tilapia and pangasius have a bright future ahead, as they can help feed a large population for an affordable price. In general, aquaculture has the opportunity to fill the huge gap left by depleted wild fish stocks, although it will have to solve some issues in order to be successful (see my article titled “The lessons of intensive animal husbandry to aquaculture“). In terms of price, the scarcity of wild fish will make these quite expensive for the future.
Less efficient species such as pigs and beef cattle will see the price of their products increase relatively much more. Pigs also have the disadvantage of producing low quality manure, which will limit the level of intensification. However, pork plays an important role in some cultures, and therefore, it will still show a reasonable volume growth, with geographical variations.
A high FCR species such as beef cattle will probably undergo the most dramatic change. Higher feed costs, linked to a relatively high capital need will probably push a number of farmers to shift to other more efficient productions. Highly intensive systems such the feedlots will also undergo major changes, as regulations on the use of antibiotics and hormones will make them financially inefficient. Further, their high impact on the environment because of the manure will also work against them. I do not expect the 99-cent beef burger to be here for all that much longer, burgers will continue to exist, but just quite a bit more expensive. On the other hand, I can see good possibilities for specialty beef products, such as grass-fed beef, but customers will have to pay the right price for it. Grass is the animal feed that we all seem to underestimate, yet it covers vast areas of very often fragile soil, and cattle is one of the few species that can transform it into high value protein.
In the aquaculture sector, a carnivore species such as salmon will also meet its own limitations. Although, salmon feed has shifted from mostly fish oil and fishmeal to a much more complex mix of vegetal oils, this production will see its production costs rise strongly. I expect salmon to become a luxury product again.
What will a higher price mean?
There again, simple economics tell us that this will influence the level of consumption per capita. The price increase will moderate the level of consumption and the price differential between the type of protein, as well as health concerns, will cause a shift between the respective consumption of the different products. In Western countries, people consume quantities of animal products that are substantially higher than what they actually need, and this has led to many health issues. The decrease in consumption will help make people healthier, and reduce the burden of health costs in that part of the world.
In developing countries, the situation is different, as consumption trends show an increase of consumption of animal products, from rather low levels, though. In these countries, consumption per capita will increase, but will not reach the levels that Western countries have shown, simply because prices will be too high to get to such levels.
The decrease of consumption per capita that we will see in developed countries does not mean that the meat industry will get into trouble. Less average consumption per capita in the West will be more than compensated by the growth in emerging countries, where population numbers are significantly higher, and this will lead to a higher global demand of animal products. The main change is that the consumers will be distributed geographically rather differently than they are today. This also means that production will be located in different areas than today.
Just as a teaser: if Western countries consumers were to reduce their meat consumption to just the necessary maintenance needs, it would free volumes enough to cover the maintenance needs of meat for the whole population of China!

Sometimes success stories do not happen at once. This is my feeling about cod farming. Cod products are in good demand, and unfortunately, wild stocks are in serious trouble, which leaves a huge opening in the market.
So far, farmed cod producers have not delivered good financial results and opinions diverge according to whom you listen. Culprit seems to be the “market”, but this is generally a very vague and inaccurate explanation.
Feed companies initiated cod farming, as an extension of the feed business, but not as a standout business. Moreover, the volumes that have been planned initially answered to a production driven approach, and not to a market-driven approach. Production was set up for quite significant volumes, without building up a solid sales plan from an already established market position for cod products. If you read my previous articles “Be always market-driven” and “The consumer must be the focus point of value chains“, you can understand why such an approach delivered poor results.
Recently, I was browsing through the web site of one of the farming companies and, although they claim to have set up a value chain, they have not quite done so. Their value chain needs to integrate much more strongly the marketing/customer end, and I think that they need to rebalance their bargaining position with feed suppliers and customers, in order to obtain a fairer distribution of profits. Today, there are people making good money out of cod farming, but the farmers are not.
Once they refocus their marketing mix to the right countries and the right type of customers, which they will have to do with a reduction of production volumes, then they can grow the business with and for the cod market by being in the driver’s seat.
Considering the demand for white fish and the depletion of the supply of the natural competitor (wild cod), cod farming’s future can only be bright. It would not surprise me if, in the future, cod farming could surpass salmon farming in production volumes. But first, one step back.

The past 50 years have seen, at least in the Western world, the development of the consumption society. The emphasis has been on consuming always more, by having an apparently unlimited quantity of increasingly cheaper consumption goods available. This trend happened in the agriculture and food sectors just as well, and followed a rather simple patter, actually. Mass consumption has been coupled to mass production, thanks to intensification, technical and technological progress and, last but not least, marketing.
Technical progress improved yields and productivity, while marketing was aimed at creating more, and new, needs. Our food has become standardized, industrialized, and processed in a wide variety of forms. As the emphasis moved to lifestyle and convenience, which came along with the rise of mass distribution, cheap energy and suburbia, we lost the connection between ourselves, the origin of our food and nature. Food became just things you buy at the supermarket, already packed in plastic and cardboard.
Now, we have come to the realization that this high production of waste, be it packaging material, be it blemished product that do not look good anymore while still perfectly edible, be it the overproduction of manure and its minerals, or be it the massive use of antibiotics and pesticides is not sustainable. Of course, much progress has already done to reduce this waste and there is a growing trend towards organic and traceable, but at this stage it not clear yet whether this is a true change in our behavior or whether it has more to do with a social status and marketing issue.
However, what the current situation might be, the fact that we understand that we cannot keep on intensifying and wasting the way we did, will inevitably bring a more fundamental change in how we consume in the future.
Some people predict such changes as the astronaut diet made out of pills, the use of a computer to tell us what and how much of it we should eat based on our activity level, or the tissue culture to replace meat, and many other scenarios. Will any of those ever happen? Who knows?
Personally, I believe that food as a very strong psychological connotation. We associate food with experiences and, although there are differences between cultures, that emotional bond will stay.
Clearly, the consumption society with all its excesses is coming to its end, and maybe the current economic crisis, which also originated in the excess of having it all at any cost, could very well be the turning point.
The next evolution is probably going to be a balanced approach between consumption, which we need to some extent, and the necessity of preserving what keeps us alive. There will be different graduations of this balance between geographic regions, but sustainability is the only way forward, as I mentioned in my previous article (Sustainability: as natural as balance).
Intensification is showing its limitations, waste of manure and of packaging are also hitting a wall, energy is getting more expensive and makes the production and the transport of food more expensive, too. This will reshape how we want to consume our food, how and where it is produced, how it is presented to us.
We still are in a society where some people get obese by eating lots of food as quickly as they can, while they have less physical activity than the previous generations, thanks to automation. That food is produced on intensive farms and feedlots where the animals grow and fatten as quickly as possible, as they eat lots of food, while not having much physical activity. Similarly, in our society meat producers use hormones to boost growth and carcass quality, while body builders and sport professionals use steroids and growth hormone to boost their performance. Interesting similarities, don’t you think? We are indeed what we eat.
So, in a conservation society, should we expect the farms to be led by the need to preserve? This almost sounds like the farms we had at the beginning of the twentieth century. I think that there will be some of it, but the efficiency of production as well as the efficiency of preserving the environment will be much better, thanks to new technologies. We will have high yields, and at the same time, we will have highly efficient systems to use water, to recycle waste and preserve the fertility of our soils and the balance of our oceans.

Here is an article (Sustainable Aquaculture: Net Profits) about a fish farm in Andalusia, Spain, which has a different angle than industrial intensive fish farms.
It refers to a number of arguments, such as feces contamination and lower densities, that I had mentioned in a previous article (The lessons of intensive animal husbandry to aquaculture). It also illustrates what I presented in Value chains are a great way to develop a niche, as they market their fish as the pata negra of sea bass at a premium price.
Of course, this farm is an example showing a very specific situation in a very specific environment, and providing seafood to the world population might require more intensive systems. Moreover, not everyone can afford to buy the pata negra category of food.

The domestication of animals for food production started thousands of years ago, and has gone through a slow evolution since then. In the last 50 years, we have intensified productions systems to a very high degree. Aquaculture, although not unusual in ancient times, has really experienced an economic boom only rather recently, and future growth predictions are quite optimistic.
The development of intensive animal husbandry has helped provide people with high nutritional value products, and it also offered the possibilities to farmers to have a reasonable source of income. On the other side, it has brought a number of problems, many of which have not been solved and this has resulted in pressure to reduce the level of intensification.
With high densities of animal in some regions, animal husbandry has had to deal with a number of health issues, such as not long ago avian flu and swine fever. The presence of large number of animals in limited areas has increased the “disease pressure” on farms and regions, making epizooties quite devastating, considering the amount of culling that health prevention measures require. This always takes a heavy economic toll, and not only on farmers. This has forced many countries to review their policies about intensive animal husbandry and downsized the sector.
To prevent diseases and mortality, intensive animal husbandry has made a widespread use of antibiotics, which also appeared to promote animal growth. Unfortunately, over time it has appeared that these antibiotics found their way into our bodies and ultimately into our drinking water reserves. The main threat that has arisen from the massive use of antibiotics is the emergence of bacteria resistance to these antibiotics, with the potential risk of making them ineffective, should bacteria become resistant to all of them. The result of this would be to bring us back to the pre-penicillin era with all the consequences that we know. Many countries have now addressed the problems surrounding the use of antibiotics and restricted their use to curative purposes.
Another strong impact on the environment has been the manure surpluses in intensive regions. Next to the odor problem, the excessive manure production has resulted in heavy pollution of the soil and of water reserves. Phosphates and heavy metals coming from the animal feed endangered the fertility of the soil. More mobile minerals, such as nitrates, have entered our drinking water, making it in many areas unsuitable for pregnant women and infants. Sadly, the intensive regions get in trouble because of a surplus of minerals that originate from raw materials produced in other parts of the world, while on the farms producing the feedstuffs, the minerals are not brought back. They have to be replaced by chemical fertilizers instead of the manure that would originate from the animals, such as in a closed system mixed farm.
Husbandry systems have evolved, too. After years of high degree of confinement, regulations have changed and are still changing to take animal welfare more into account. As examples, I could give the stop on tethering of sows and hen cage ban. I have no doubt that animal welfare will become a growing issue in aquaculture, too.
The use of feed and its constant quest to reduce production costs has brought the industry to use some raw materials that can be questionable. An example of this was meat and bone meal use, after the mad cow disease hit Britain in the mid 1990’s. Next to the possible transmission risks to humans, it has also raised some questions about whether herbivores should consume meat derivates.
Intensive animal husbandry has made meat, dairy and poultry very affordable to most consumers, at least in the Western countries. This has led to a shift in the diet from mainly starch to a much higher proportion of protein and fat. Unfortunately, this shift has had some negative effect on health. Animal products are high value sources of protein and fat, but excessive consumption has negative effects. While an annual consumption of 30 kg of meat per capita would do just fine, most Western countries have passed the level of 100kg. Of course, there are many discussions between the different parties involved about where the truth lies, but there are good indication that a good diet should include more fiber, more produce and less animal protein and fat.
Therefore, above, I have tried to sum up the most noticeable results of intensification of land animal production. Clearly, there are lessons to be learned for the “new” aquaculture industry, and by this, I mean the intensive, high investment aquaculture. Most companies involved in this business have been inspired mainly by the evolution-and the success- in the chicken industry. They try to copy and adapt a similar model. Therefore, it is rather predicable that they will have to deal eventually with similar consequences.
Fish farms have very high densities of animals. Even if the area at the sea level is rather limited, each farm goes quite deep, and the biomass they contain would make many chicken farms look like “small” operations. If you add to this that they are very exposed to the natural environment, as the pens are open nets, there is no wonder that they are very exposed to disease and disease spreading. The current situation in the Chilean salmon farming sector facing ISA just shows how sensitive these farms can be to diseases. My expectations is that aquaculture will be confronted to situations as bad as swine fever and avian flu, and they will have to revise their level of intensification, their location (including possible rotation of site with fallowing as a standard procedure). Further, navigation rules will be strengthened to reduce the possibility of cross-contamination from a marine zone to another.
Very likely, the sector will also further sharpen its veterinary procedures and increase their control on prevention and on medication. About this part, it may seem that feces simply get flushed into the ocean, but that is not that certain. Feces always contain residues of medicines. The volume of feces produced is quite significant on such intensive fish farms and you can be sure that at some point, simply letting them go into the sea will not be allowed anymore. I foresee that fish pens will have feces collection systems in the future and the “manure” will have to find some use.
The feed industry is now diversifying it sources of raw materials to cope with the rising price of fish oil and fish meal, which is the result of higher demand from the fast growing aquaculture. They carry out lots of research to find the right profiles of oil to meet the fish flesh quality requirements (especially omega3) by using vegetal oil, but one can wonder whether this will be a sustainable approach in the long run. Maybe there will be a completely new industry to produce “farmed” fish oil and fish meal to meet the feed industry needs.

Since the beginning of times, feeding a population has always been about balance.
When mankind was still in the stage of hunting, fishing and gathering, survival was about keeping resources at a level that would allow the group to keep on feeding from its close environment.
When agriculture started, followed by the domestication of what became farm animals, the idea was clearly to have more control on the resources and insure that they would be available on a more regular basis. Of course, there were times when this did not happen, but the principle has remained.
For many centuries, agriculture was a local activity. Farmers would grow a diversified group of products that insured a sustainable balance at local level. The different products were a reflection of seasons and of land diversity. They also would offer different activities, and some revenue, through the different times of the year.
Their productions were part of a cycle. For instance, farm animals would eat crops coming from the farm to produce meat, milk, eggs which are all related to the reproduction cycle and the continuation of their species. What would not be digested, as well by the farm animals as by the local human population would return to the land as manure (usually mixed with a crop by-product such as straw to provide and insulating litter), fertilizing the next round of crops. So basically, what was extracted from the Earth was returning to it, thus insuring the continuity of the system, for as long as the climate would support it.
With the growth of world population and the increasing mobility and later globalization of markets, this very local and sustainable system has evolved. Products are sold far away from their area of production; many farms have specialized and replace the manure cycle by purchase of fertilizers. Animals are fed with raw materials originating from the over side of the world. Genetics, crop engineering, technical progress have also allowed yields to sharply increase as well as the speed of the production of foodstuffs, vegetal and animal. This has benefited mankind on the shorter term because it provided more food at relatively cheaper prices, so more accessible to a larger group. This has benefited trade and business, but it has brought its toll on the balance that is the cornerstone of any biologically related activity.
For example, intensive animal husbandry was developed in poor regions, allowing farmers to have a decent revenue in areas were they could not have stayed, but as the animals were fed with non-indigenous feedstuffs, they produced massive amounts of manure that were much higher than the local ground could process. This has led to loss of soil fertility, as a result of excess phosphates in the ground, among other things. Water resources have been polluted with high level of minerals, such as nitrates making it risky to use for infants and pregnant women. The exclusive use of chemical fertilizers in crop areas, as a result of the disappearance of a mixed farming also led to lower levels of organic matter (which is crucial to fix minerals and make them fully available for plants) and has caused some severe erosion of very fertile soils. While these problems were growing in the West as we were putting too much back on the land, on the other side of the world the opposite situation was happening with an exhaustion of soils to produce crops aimed for export only, which resulted in taking more out of those soils and not returning it in the right form. Further, these regions developed very often these commercial crops on land that had been won from ecosystems such has tropical forests, which have very sensitive soils to rain, erosion and oxidation of metals such as aluminum and iron.
By bringing the natural cycles out of balance, we have weakened the Earth from providing us optimally with what feeds us. Our future and our sustainability will depend of our ability to manage this balancing act. As usual, what seems a challenge can also offer new opportunities!

The world population is increasing at an amazing rate.
From 6 billion people on the planet in 2000, we will be 9 billion by 2050; an increase of 50%; and we were only 3 billion in 1960.
By looking how much damage has been made to the environment and the huge depletion of natural resources that we have created in the last 50 years (or last time the population grew by 3 billion), one can wonder how we will be able to feed, shelter, provide water and energy to the whole population in 40 years from now.
When it comes to feeding the world, the first question that comes to mind is where can we produce 50% more agricultural products on a land area that will decrease as a result of more area needed for urbanism (unless, we grow cities in height) and 50% more demand for drinking water than now. And these percentages are actually very conservative if we think that the emerging countries are seeing their standard of living increasing, which unfortunately also means that more resources are wasted than just the incremental growth of 50%.
We need to feed 3 billion people more who on average will tend to eat more animal protein at the expense of grain and legumes. This demand for animal protein means more competition between humans and farm animals for the grains and legumes. So, we have less land available to grow so much more food of vegetal and animal origin.
We could consider increasing the agricultural area, but this means more deforestation and a strong reduction of natural habitats. More agriculture will mean more use of energy and water, which will have a huge impact on our environment and the price of commodities. And I am not even taken in the picture the fact that we also want to feed our cars with agricultural product, bio-ethanol.
On the other side of things, we hear more and more calls to restore more balance our environment, to use our resources more carefully. And this is the challenge, if not the dilemma of the coming years: we have only one Earth and it is not expandable, while our population is exploding.
How will we be able to meet both targets? Personally, I do not have the answer to this, but I am sure of one thing: a dramatic change must come, either of our own free will or forced by Nature, and we need to anticipate for this as this will require an adaptability as mankind has not known for a long time.

Sorry to crush George W.’s and Star Trek’s fans’ illusions, but I believe that colonizing oceans could offer more interesting possibilities than outerspace. Mars… well that’s another story…
OK, so, let’s start daydreaming!
First, a look at the scenery.
Close to 70% of the Earth is covered by water.
Most of that volume is left unexploited, with exception of fisheries, which unfortunately deplete stocks, mostly because there is no efficient plan to manage fish stocks in a sustainable manner.
The timid colonization efforts are limited to fairly coastal activities.
Natural resources
While on the land, it has become more and more difficult to extract metals and minerals, there is a vast hardly explored potential for these natural resources lying at the bottom of the sea. Many open-sky mines have been exploited to almost full potential. Drilling and mining at deeper and deeper levels have resulted in higher and higher costs. All things considered, it is probably cheaper to drill through a layer of (soft) water than hard rock, and there are areas known where metals are available on the surface of the oceans bottom.
Energy
Tremendous energy potential is available in and over the oceans.We have huge reserves of hydrogen in there. Of course, to produce it we will have to produce the necessary energy to split the water molecules. Using fossil fuel cannot be an option, as the gas emissions would defeat the purpose.
The great thing is that the energy needed can be found in the oceans themselves. Why not think of having large wind or solar farms located on oceans (probably not too far offshore), dedicated to splitting water and producing hydrogen and oxygen. The hydrogen could be used in fuel cells, and the oxygen could be used to allow the people involved in underwater activities and settlements to breathe.
Further, more electricity can be produce by using the strong currents to run through turbines.
It could be also interesting to consider the possibility to create floating solar energy farms.
It such a scenario, it is not unthinkable that all our energy needs for cars, factories and industries could come from clean emission-free electricity.
Water
Water, and especially clean drinking water will be one of the biggest challenges that mankind is going to face in the future.
Of course, there is plenty of water in the oceans, but the main problem will be to make it drinkable.
Considering that in the fantasy I am writing here, I envision human settlements on (or in?) the oceans, there will have to be drinking water available.
Next to desalinization, the other most obvious source of drinking water is collecting rain.
Capturing carbon
There are projects of using minerals to change the pH of the sea with the hope that this would help absorb CO2 much faster than it naturally currently happens. Although, this might be our last resort if we do not get our emission under control. The problem is that we have about no idea on what the side effects on the ecosystems might be, and that is a scary thought.
Here, I want to focus on more positive ways to use ecological methods.
On the land, we are losing more and more trees as a result of our need for more and more land, and therefore we are losing the natural capacity to capture CO2.
Then why not think of replacing these lost trees by cultivating the oceans and develop large vegetal populations, in other words, grow aquatic meadows and forests?
This must be done with care of course as the ocean life is a three dimensional thing with depth playing a significant role, while on land it looks more like two dimensional (limited depth/height significance).
Another area of attention when developing such vegetal populations is to make sure they do not get out of control and impact the oceans ecology as many other species with interact with them, creating complete ecological systems and food chains.
Developing a whole new aquaculture
Here, I use this term in its literary meaning, which is cultivating the water, not just restricting it to the production of a few commercial aquatic species, as it is the case today.We should be able to cultivate the water en develop it in a similar way as we did with agriculture, but also by learning from the mistakes we have made in agriculture.The only way that the current aquaculture farms can survive is to produce (cultivate) the foodstuffs it needs in the oceans as well. Keeping on doing as today has probably not that much future, as the need for fish meal, and mostly fish oil will exceed by far the current production possibilities, and exhausting the wild stocks used for that clearly could not work. Further, replacing these foodstuffs by vegetal protein and fat from agricultural crops will not work, either, because there will be too much competition from the needs for land-based animal productions and the needs for human food. Clearly, the only way to meet the increasing needs for seafood is to grow the foodstuff in the sea.
This opens a tremendous project of picking which foodstuffs to produce in the sea, how to manage them, how to combine the mix of production and ensuring the sustainability of this new aquaculture, and at the same time ensuring that the marine ecosystems recover and function properly as well.
This will require an aquaculture of plankton, of algae, of aquatic plants, of fish, of shellfish, of mammals en maybe more.
So far we have depleted the food chains in the sea, now is the time to restore them, next to increasing our ocean-based food supplies.
The challenges
Well, you will say: that sounds all very nice but is it realistic?
And I would answer, maybe it is not quite realistic today, but if we work on it, quite a few things named above can be achieved. Actually, some have already started.
The main challenge I see is to cope with the tremendous forces that oceans can unleash, such as currents, storms, waves and pressure in the depths; and we would need to build in a way that can deal with such forces, if we want to avoid disasters.
But you have to agree that there is lots of space available on our planet this way and it here right here “at home”.
