Without water, there is no agriculture, there is no food, and there is no life. It is obvious, and yet the water question is too often
neglected. The quantity and the quality of water available are absolutely crucial for the future production of food. It will influence where and what type of food we can produce. It will define food security and world politics. Since 70% of fresh water use is for agricultural purposes, it is clear that water will soon be power.
The need to preserve water and use it efficiently is going to be one of the main challenges to overcome for the decades to come. This will stimulate innovation and the development of new technologies and new techniques.
Field sensors that measure the level of humidity in the air and in the soil connected with “crop per drop” irrigation systems can allow the distribution of the right amount of water at the right time, thus saving waste through evaporation and drainage. The selection of plant varieties will focus more and more on water efficiency. Drought-resistant plants that can thrive in arid conditions are in the works. For instance, a trial on wheat in Australia has delivered promising results, as the yield was 25% higher than non drought-resistant varieties. Researchers, through hybridization and genetic engineering, are working to develop varieties that can use less water and produce similar yields as per today. Although high tech may bring solutions, other methods deliver good results, too. Agro forestry, the production of crops under a cover of trees seems to help farmers achieve satisfying results in the Sahel region. The foliage of the trees helps reduce evaporation from the soil. Combined with proper techniques to apply organic matter and fertilizing elements, farmers can create better conditions for plants to grow.
Another field of research is the development of alternatives to traditional desalination, which is very demanding in energy. Transforming seawater into fresh water for the production of food is not simple, and it is expensive. The technology is here. Israel has used it for decades. Currently in the United Arab Emirates, a project of floating islands covered with solar panels to provide the energy to desalinate seawater is being developed. This system has the advantage to produce both fresh water, which is precious in desert countries and clean energy at the same time. A project, called The Sahara Forest Project aiming at producing food in the desert is currently in the works. It combines solar energy, modern biomass production and a type of greenhouse, built by the Seawater Greenhouse company, that helps the humidity produce by the plants to condensate.
In many countries, the problem is not so much physical scarcity of water as it is a lack of proper infrastructure to collect, pump and irrigate efficiently. The population density contributes to the problem, because the more people, the less for each of them. In many countries, for instance in India, the equipment is old, inadequate and poorly maintained, because of a lack of finance of governments and farmers. The result is a waste of water resources, and a suboptimal production. Another area that has potential for improvement is the collection and the storage of rainwater. A large quantity of water runs off and is not available for food production because there are not enough containers, if any. Developing and improving storage infrastructure will definitely help farmers to produce more food.
If the availability of water is important, so is its quality. In China, the situation is a lack of both, because of the heavy pollution of many streams and rivers. In many areas, the water is there, but it cannot be used, as it is fit neither for human consumption nor for agricultural production.
The respective situation of countries about water availability will determine their ability to feed their own people or not. In Arab countries, irrigation has led to a high level of salinity and it has depleted drinking water reserves. Saudi Arabia, for instance, has now abandoned its policy of increasing food production to become be self-sufficient. Saudis are actively purchasing land in African and Asian countries to meet their food needs. China and India, that represent about 40% of the world population, are following a similar approach and invest heavily to help develop land in Africa. In countries where drinking water is scarce, there are discussions about the need of not exporting, as export of food is actually water export as well.
If a number of countries face a water shortage, others have a different situation. This is the case for large areas of North America and South America. Especially Brazil disposes of large water reserves. Together with a favourable climate, Brazil has many advantages to produce food, especially animal protein. According to Osler Desouzart of OD Consulting, the production of 1 kg of beef requires 16,000 litres of water, while it takes 6,000 litres for 1 kg of pork and only 2,800 litres for a kg of chicken. This shows why Brazil has been gaining market share in beef and poultry. It indicates that intensive animal production will be more challenging in countries where water is not as abundant. This also tends to show that poultry will be the most successful type of land animal production. The US and Canada have large water reserves, although there are also clear regional differences. The South West of the US becoming increasingly arid, and one can wonder if California, that currently produces most of the fruit and vegetables for the North American continent, will be able to keep its production levels. It is likely that fresh produce will be gradually produced closer, even inside, the large urban centers in the northeast as well. Considering the emphasis on water preservation, it is also interesting to note that before the housing crisis in the US, the most irrigated type of plant production were lawns, using three times as much water as US corn. Food recalls are another source of water waste, especially meat and eggs recalls. From the numbers presented above, it is easy to see how much water is lost when dozens of tons of animal products must be destroyed, not to mention the huge food waste that this represents.
When it comes to food and water, aquaculture offers interesting possibilities for the efficient production of protein. Fish produced in the ocean do not consume freshwater. This saves large amounts that can be used for other purposes. However, one of the challenges for the fast-growing aquaculture industry will be to be able to source feed ingredients that do not directly compete with other farm animals and direct human consumption. Land-based aquaculture is developing the very interesting concept of aquaponics, which is a combination of fish production in tanks combined with the production of vegetables indoors. The system recycles the water used for the fish tank, and helps fertilize the plants with fish waste. This is a very water–efficient system that can help produce large amounts of food on a small area, making it fit for urban farming units.

For most customers, white eggs are perceived as being from intensive cage production, while brown eggs are perceived as being more “natural”. Everyone with knowledge of the industry knows that the color of the shell has nothing to do with the nutritional quality of the egg. The belief that the egg color indicates a difference persists, though.
Of course, it would be interesting to imagine what people would eat if they were rational, and what impact on our food production this would have. A rational diet would follow proper nutritional recommendation, and to this extent would follow the same principles as those used in animal nutrition. However, this would not have to be as boring a diet as what animals are fed. A rational diet does not need to be a ration. After, the human genius that is cooking would help prepare delicious rational meals. It would be like having the best of both worlds. The emotional, social and hedonistic functions of food would remain. The key would be about balance and moderation. If people were eating rationally, there would not be any diet-related illnesses. There would not be obesity. There also would be a lot less food waste. This would improve the level of sustainability of agriculture.
To attract new people to the food sector, it is also quite important to tell what kind of jobs this sector has to offer. These jobs need to be not only interesting, but they also must offer the candidates the prospect of competitive income, long-term opportunities, and a perceived positive social status. Many students have no idea about the amazing diversity of jobs that agriculture (including aquaculture) and food production have to offer. This is what both the sector and the schools must communicate. Just to name a few and in no particular order, here are some of the possibilities: farming, processing, logistics, planning, sales, marketing, trade, operations, procurement, quality, customer service, IT, banking and finance, nutrition (both animal and human), agronomy, animal husbandry, genetics, microbiology, biochemistry, soil science, ecology, climatology, equipment, machinery, fertilizers, irrigation, consumer products, retail, research, education, plant protection, communication and PR, legal, management, knowledge transfer, innovation, politics, services, etc… Now, you may breathe again!
What are the risks of a mismatch of values? It can have serious consequences, depending on how much of your business is engaged with the “wrong” partner. It can range from dissatisfaction about the profitability of your business, constant disagreements and tensions with your business partner, to your being ripped off. One thing is sure: there will never be complete trust and loyalty when values are not aligned.
fact, they will hardly listen. Therefore, words will have little impact, unless they go along with actions that confirm that the message is true. If the food industry does not want to change and hopes that communication will be enough to change the public’s mind, nothing will change. When you want someone to prove to you that he/she is reliable, you want to see tangible proof that something is changing in your favor. The most powerful communication tool that really works for regaining trust is the non-verbal communication. The distrusted one must sweat to win trust back. This does not take away that verbal communication must continue. It will keep the relationship alive, but it will not be the critical part for turning around the situation.
This time, there is one major difference. With 9 billion people in sight by 2050, the consequences of our actions will have much more impact, negative as well as positive, depending on where we live. In 1950, there were “only” 2.5 billion people on Earth. Compared with today, one could argue that there was some margin for error by then. This margin for error is now gone. Therefore, it is necessary to think ahead and consider all the things that might go wrong. We must anticipate before we have to react.
Poultry and pork show the strongest increase.
So, who will they be and where will they be?
