Aquaculture: the solution to feed 9 billion people?

Posted on December 8, 2009 by Christophe Pelletier

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!

The vertical farm

Posted on October 26, 2009 by Christophe Pelletier

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.

The hot regions of the future

Posted on September 18, 2009 by Christophe Pelletier

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.

Bringing cities to the countryside: Infrastructure will help rural development

Posted on September 16, 2009 by Christophe Pelletier

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. Maslow's pyramid of needs - Picture Wikipedia 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 and environment as growing drivers of food production

Posted on September 10, 2009 by Christophe Pelletier

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.
A little bit of this... 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.

How much can the rule of 80-20 tell us about the future?

Posted on September 3, 2009 by Christophe Pelletier

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
Producing more, yet in a sustainable way. That is the challenge! 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
Closer to nature 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 “developed” countries to serve a increasing, but aging, population more demanding about the origin and the production methods, and who is ready to pay a premium for the perceived better quality. The angle will be about quality, transparency, sustainability, traceability and as close to zero a use of chemicals and pharmaceuticals. In some areas, it could help strengthening a local economy and local communities.
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.

High-tech fish farm

Posted on August 31, 2009 by Christophe Pelletier

Hawaii Oceanic Technology Inc 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.”

The fish farming of the future?

Posted on August 21, 2009 by Christophe Pelletier

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.

Photograph Ocean Farm Technologies 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“

Innovation and tradition shape the future

Posted on August 12, 2009 by Christophe Pelletier

Tradition in food can be quite resilient 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:

Reducing physical labor.
Helping us live better and longer.
Increasing efficiency.
Helping communication.
Increasing mobility.
Offering more leisure and entertainment.
Making some people a little wealthier.

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).
More mechanization, automation and robotising, especially in software more than hardware, working on precision (intelligent technology).
Greater focus on health and natural solutions for food and for agriculture/aquaculture/fisheries (objective: zero residue and zero contaminants in water, air, soil, and food).
Projects to repair environmental damage and include agriculture/aquaculture/fisheries in environmental management (restore and maintain sustainable food production).
Policies, and politics, to increase food production (disease control, regulation, more government intervention at strategic level, incentives).
Redistribution of markets with geographical shift of production and consumption areas.
Shift from convenient to practical food solutions (bulk meal components).
More education on agriculture, food and nutrition (balanced diets, food safety, traceability).

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.

Rebuilding fisheries is a must for the future

Posted on August 5, 2009 by Christophe Pelletier

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.
