To assess the likely impact of climate change on U.S. agriculture, researchers typically run a combination of climate and crop models that project how yields of maize, wheat and other key crops will change over time. But the suite of models commonly used in these simulations, which account for a wide range of uncertainty, produces outcomes that can range from substantial crop losses to bountiful harvests. These mixed results often leave farmers and other agricultural stakeholders perplexed as to how best to adapt to climate change.
A new study points to the risk that China and India will be facing severe water shortages by 2050 due to a perfect storm of economic growth, climate change, and fast growing populations. Joint Program Deputy Director Adam Schlosser comments on the future of water stress in Asia.
MIT study to investigate exposure pathways and mitigation opportunities
Evaluation of land resources by the U.N.’s Food and Agriculture Organization suggest availability of arable land itself is not a major constraint on food production at least through mid-century, assuming continued yield improvements. There are, however, some wild cards that could vastly impact agriculture in the coming decades.
