That time will most likely come around 2050 if current projections are true, when the world’s human population is set to reach the nine billion mark. The chart below was presented in a recently published paper in the journal PLOS ONEA , authored byA Deepak Ray, Nathaniel Mueller, Paul West and Jonathan Foley, which indicates global crop yields evolution since forty years ago and how these are projected to grow in the next forty years, a time when the human population will reach a critical milestone.
The solid lines in the graph reflect projected crop yields, while the dashed lines show how productivity would need to grow in the future to supply growing demand. Yield growth needs to be accelerated if the the projected demand for food, nearly double that of today, is to be satisfied. Lack of investment in agriculture and poor enforcement of policies are just a few reasons why this stagnation in growth is happening right now in many parts of the world.

There is enough land available to produce more food, more feed and more biofuels, which are not the cause of global malnutrition problems, according to the World Bioenergy Association.
WBA makes this declaration in a recently released, fourth publication of a series of documents intended for media and industry use as verifiable, easily-referenced sources addressing global bioenergy usage and potential. In 2010, about 84 million metric tons of conventional biofuels based on crops containing starch, sugar or vegetable oil were produced, representing 104 billion liters of fuel, or 2.7 percent of the global demand for transportation fuels, according to the WBA. On the effect of biofuel production on food prices, the paper says that while agricultural commodity prices have been fluctuating over the past decade and were particularly high in 2007-’08, a number of different factors have influenced them such as increasing fossil oil prices, bad harvests (as a consequence of extreme weather situations), growing demand of food for an increasing population with changing eating habits, slower improvements in productivity gains due to low investments in agriculture, and the production of biofuels, which WBA says has the most minor impact of those factors, citing that several studies also indicate that higher commodity prices have many positive effects in the global agricultural commodities market.
The WBA concludes that there’s a need for a continued, well-balanced further growth in the production of biofuels for transport, and calls for intensified efforts to achieve the market introduction of advanced biofuels based on cellulosic feedstocks. Foley thinks we need to address these issues if we’re to successfully tackle 2050 and the incoming global food crisis.
Thing is, crop fields are already stretched almost to their limits, and making room would mean making dramatic compromises like deforestation, something far from being a sustainable approach. If you check out the graph closely, though, you’ll see that corp yields have truly risen dramatically.


Like I said earlier, it’s simply amazing how farmers have managed to double their yields in 50 years. I’m sure many of you have been grinding your teeth while reading through all of this citing rubbish. In nearly 50 years, farmers have managed to double their crop yields, mostly due to the advent ofA A synthetic fertilizer and modern agricultural techniques.
Genetically modified crops might push the barrier even further, but really how much strain can these crops sustain? Namely, farmers need to improve their crop yields so that they may produce more food from the same surface of crop land, and in all good faith this is exactly what they have been striving to do for a long time. Thing is, wasting food will always be an issue, and even if we cut down on wasting, we still need to GROW MORE.
