Climate change is expected to have a big effect on agriculture and food security, but the effect will be different in each region and for each crop. With the world’s population growing, agriculture needs to change quickly to make sure that people will have enough food in the future. Adaptation strategies include changing how land is used and how crops are grown, making better crop varieties, and changing how much food is eaten and how much is wasted.
- Temperature increases are expected to reduce maize yields by the end of the century.
- Weather, crop and land management, pathogens and pests, and extreme weather events all affect agricultural yield.
- To prevent climate change from worsening, people, governments, and the international community must reduce GHG emissions.
