Over the last century, the global population has quadrupled. In 1915, there were 1.8 billion people in the world. Today, according to the most recent estimate by the UN, there are 7.3 billion people — and we may reach 9.7 billion by 2050. This growth, along with rising incomes in developing countries (which cause dietary changes such as eating more protein and meat) are driving up global food demand.

Food demand is expected to increase anywhere between 59% to 98% by 2050. This will shape agricultural markets in ways we have not seen before. Farmers worldwide will need to increase crop production, either by increasing the amount of agricultural land to grow crops or by enhancing productivity on existing agricultural lands through fertilizer and irrigation and adopting new methods like precision farming.

However, the ecological and social trade-offs of clearing more land for agriculture are often high, particularly in the tropics. And right now, crop yields — the amount of crops harvested per unit of land cultivated — are growing too slowly to meet the forecasted demand for food.

Many other factors, from climate change to urbanization to a lack of investment, will also make it challenging to produce enough food. There is strong academic consensus that climate change–driven water scarcity, rising global temperatures, and extreme weather will have severe long-term effects on crop yields. These are expected to impact many major agricultural regions, especially those close to the Equator. For example, the Brazilian state of Mato Grosso, one of the most important agricultural regions worldwide, may face an 18% to 23% reduction in soy and corn output by 2050, due to climate change. The Midwestern U.S. and Eastern Australia — two other globally important regions — may also see a substantial decline in agricultural output due to extreme heat.
