evidence: There is a big shortfall between the amount of food we produce today and the amount needed to feed everyone in 2050. There will be nearly 10 billion people on Earth by 2050—about 3 billion more mouths to feed than there were in 2010. As incomes rise, people will increasingly consume more resource-intensive, animal-based foods. At the same time, we urgently need to cut greenhouse gas (GHG) emissions from agricultural production and stop conversion of remaining forests to agricultural land. [...] Course 5: Reduce Greenhouse Gas Emissions from Agricultural Production GHG emissions from agricultural production arise from livestock farming, application of nitrogen fertilizers, rice cultivation and energy use. They’re projected to rise from 7 to 9 gigatons per year or more by 2050 (in addition to 6 gigatons per year or more from land-use change, not shown in the chart below). This course addresses each of these major emissions sources.
