Climate change results in more frequent heatwaves, extreme rainfall, drought and rising sea levels, which negatively affect crop yields. More land is thus needed to grow crops, increasing land competition with other food systems that use crops to feed their animals . Where land will be flooded, humans cannot grow crops, but food production could be adapted to grow seafood instead. Extensive land allocations aiming at reducing carbon emissions, such as afforestation, reduce land availability for food. Unless carefully managed, competition for land will increase food prices and food security.
