The cost of offsetting projected crop yield losses

Tuesday, June 30th, 2020

Investments in agricultural research and development (R&D) will be critical for offsetting the negative impacts of climate change on the global food system. Professor Tomas Hertel (Agricultural Economics) and co-authors sought to quantify the cost required to make such an investment effective. They concluded that increased R&D adaptation investments of between $187 billion and $1,384 billion between 2020 and 2040 would be necessary to counter the projected crop yield losses due to climate change. They noted that while this cost is 16-118% higher than current spending trends, such an investment would offer considerable benefits in terms of economic returns, food security, and environmental sustainability.
