By 2050 humanity's ranks will likely have grown to nearly 10 billion people. In a scenario with moderate economic growth, this population increase will push up global demand for agricultural products by 50 percent over present levels projects The Future of Food and Agriculture, intensifying pressures on already-strained natural resources.

At the same time, greater numbers of people will be eating fewer cereals and larger amounts of meat, fruits, vegetables and processed food — a result of an ongoing global dietary transition that will further add to those pressures, driving more deforestation, land degradation, and greenhouse gas emissions.
