The recent climatic events, in particular droughts, have attracted more attention on future challenges for food production, and rightly so. Unfortunately, the mainstream media cannot help presenting the as all gloom and doom. Certainly, there are very serious reasons for concerns, but solutions can be found. I wish the media would present more examples of positive actions to face and overcome the challenges.
It is not easy to deal with a changing environment, especially when it is impossible to predict accurately what the change will be. Predictions about temperature increases are useful but they are quite insufficient. An increase of 2 degrees on average will be different if the standard deviation is 1 degree or if it is 20 degrees. Other factors such as hours of sunlight and precipitations (including their nature, frequency and intensity) will impact agriculture at least as much as average temperatures. Changing climatic conditions will not only affect plant growth and development, but they will change the ecology of weeds and pests as well and that needs to be factored in future forecasts and models
A special attention on water is necessary. Without water, there is no life. Unfortunately, over the past few decades, wasting natural resources has been a bit of a way of life. The issue of food waste has finally received the attention it deserves, but the waste is not just about food. It is about all the inputs such as water, energy, money, time, and fertilizers. Water is still wasted in large quantities. Just compare how many liters a human being needs to drink compared by the amount of water that is flushed in bathrooms every day. Before the housing crash of 2008 a study in the US had estimated that lawn watering used three times as much water as the entire national corn production. But the issue of water is not just about waste. It is also about preserving water reserves. The late example of the drought in California illustrate what water scarcity may mean for food value chains. California is not only a major agriculture power house, but it exports a large part of the production outside of the state’s borders. The issue of water scarcity and the dwindling level of the Colorado River are not new for Californian agriculture. It has been known for a couple of decades that problems were coming. California produces a lot of water-rich fresh produce by means of irrigation. It actually has been exporting its water in the form of lettuce, spinach, melons, strawberries and citrus far away to places from where the water will never return to California. The water loop has been broken wide open and that is why, among other reasons, the system is not sustainable. If California can no longer supply its current markets, it will have to rethink its target markets. At the same time, other regions, that may not be competitive with California today, because externalities are never included in the cost of production, will eventually take over and replace the Golden State as suppliers for some productions. Unfortunately for the future, California is not the only region with a water problem. Saudi Arabia changed its food security policy a couple of years ago as the country leaders realized that trying to produce all its food would lead to a severe depletion of its available drinking water reserves. Instead of pursuing food self-sufficiency at all costs, the country chose to find other supply sources through international trade and through the purchase of farmland in foreign countries. The examples of California and Saudi Arabia demonstrate how natural –and demographic- conditions shape food value chains. The issue of water is not just about produce. Animal productions require usually more water than vegetal ones. In the future, water availability will surely affect where which kind of animal products are produced. New regions will arise and old traditional ones may review their strategies from volume-driven to higher margin specialty animal products market opportunities because of environmental constraints.
Climate change and water scarcity show how international trade can actually contribute to food security when done responsibly and with long-term vision. The prevailing model of producing where it is cheapest to produce without taking into account negative environmental externalities is facing its own contradiction and demise. The next model will be to produce not only where it is the cheapest to produce but where it is sustainable to do so. When water runs out, it is no longer possible to ignore the externalities of a production. When water becomes scarce, it gets more expensive. The law of supply and demand commands. When inputs get more expensive, several things happen. The economic model shifts. Priorities and externalities change, too. At first, producers try to find ways to increase efficiency and eliminate waste. The benefits outweigh the additional costs. Uncertainty stimulates innovation. New systems, or sometimes old ones that found a second youth, replace the current ones. If that does not work well enough, then producers start considering producing something else to ensure the continuity of their operation and find new business.
It is not the first time that our natural environment changes. Finding successful solutions to deal with it really are about our ability to adapt and to preserve our future, as it has been the case in the past. The challenges may be of a magnitude like never before, but so are our knowledge, our technical abilities and the tools present and future.
From an agricultural point of view, adapting to a new environment is about finding the type of production that thrives under new conditions. It may mean different areas of production for some species. In North America, there is already a shift for corn. Iowa has traditionally the main grower, but the corn production area is now expanding north. Minnesota is now producing more corn than in the past and so are the Canadian Prairies. Similarly, the production area for soybean is shifting north. Minnesota is growing an increasing volume of soybean and even in the province of Manitoba in Canada, soybean production attempts have been carried out since a few years. It is the result of better production conditions and the development of new varieties that can adapt to new less favorable climatic conditions. Because of the local supply for soybean, the development of aquaculture with local soybean products for fish feed is now considered a long-term possibility in Minnesota among others. In Europe, corn production regions also saw a shift to the north for corn during the 1970-80s thanks to the development of new varieties, which largely contributed to the growth of dairy production in these new areas through the widespread use of corn silage. For the future, there is no doubt that genetics will contribute again to ensure food security. There is currently a lot of work done to develop varieties that can withstand droughts, floods or soil salinity. The ability to know the complete genome of species, to spot genes through gene markers, to be able to create new varieties that are less sensitive to diseases help speed up the development of crops that can thrive under future conditions. The recent developments in synthetic biology are quite interesting. Research conducted at the IRRI (International Rice Research Institute) on the development of rice varieties that can have a higher photosynthesis efficiency and thus higher yields could open new perspective for a more productive and more sustainable production.
Next to the development of better and more adapted seeds and genetic material, the development of new technologies that I described in a previous article will bring a number of effective solutions as well. In particular the rise of precision agriculture is certainly quite promising. The ability to deliver to the crops exactly what they need when they need it at the right time and at the right place in the right quantity will help reduce the environmental impact of agriculture while offering the possibility of delivering higher yields. Similarly, in animal production, there still is room to improve feed efficiency. It can happen through further genetic improvement, the use of more efficient feed ingredients and feed composition and through better farm management. The latter is definitely an essential facet of a better future for food production. Better and updated skills for food producers will help being more efficient, more productive and more sustainable at the same time.
An area that is often forgotten when it comes to the future of food is the functioning of markets. If demand for certain products, and in particular animal products, increases faster than supply, price will go up and there will differential increases between the different types of products. As most consumers, unlike what marketers sometimes tend to make believe, still choose what they eat depending on the price of foods, there will be shifts. Some productions will thrive while others will struggle.
As prices still will be an essential driver of the location of the various vegetal and animal productions, markets and environmental constraints will increasingly have a joint effect. In the future, the dominant economic model of producing where it is the cheapest to produce will evolve. As the pressure on water supplies, soil conditions and pollution issues will keep increasing, the model will include an increasing share of negative externalities. They are the long-term costs that are never factored in the production costs but that will affect future production economics. Externalities are the hidden side of sustainability and they will determine the future map of agriculture, as it will no longer be possible to ignore them. Choices will have to be made between short-term financial performance and the long-term ability of various regions to be able to produce, and to keep producing, the volumes and the quality specifications that are needed by the different food markets of the future.
A friend of mine told me a couple of years ago after a trip to Asia how she could see from the plane the large plantations of palm oil trees, and how they had replaced the jungle. She described her impression as the view resembled the strategic game of Risk to her. Yes, climate change and water availability in particular, will reshape food value chains because agriculture, regardless of it scale, is a strategic activity. It is about life and death. It is about peace and war. Future strategies for both global commodities as well as for local food value chains will integrate Nature’s new deal of precious resources and conditions of productions. Together with the geography of future consumption markets, world agriculture will readjust, relocate and the Earth will look different once again.
