- In the next 25 years, we will have to produce more food than we did in the last 2,500 years.
- We need to grow more food with less land, water, and other critical inputs, since these are already limited and under increasing demographic and environmental pressures.
Let's consider the second part: climate change makes matters worse for food security and nutrition. - Changes in climate threaten to reduce existing yields of crops like wheat and corn - critical for global food security. Food prices of these crops are projected to double, as a result.
- Increased levels of atmospheric carbon threaten to reduce the nutrition content of these crops, by reducing their protein levels or micronutrients such as zinc - compounding the challenge of not having enough food, with that of not having enough nutritious food.
In Africa, we see the very real effects of climate change on agriculture. Former thriving breadbaskets such as in Northern Nigeria are teetering due to years of underfunding and policy inattention. Outside corn, our food security depends on crops like sorghum, millets, cassava and sweet potato--termed 'orphan crops' due to lack of research attention relative to rice, wheat, and corn....
