A study indicates that U.S. agriculture may face declining productivity due to climate change and insufficient research funding. It calls for a 5-8% annual increase in research investment or an additional $2.2 billion to $3.8 billion yearly to sustain agricultural productivity through 2050. The necessity for public sector research, with its broader social benefits, is also emphasized.
A recent study published in the Proceedings of the National Academy of Sciences indicates that U.S. agriculture is facing significant productivity challenges due to climate change and declining research investment. Researchers emphasize the need for a growth rate of 5% to 8% in research funding annually to counteract these effects, echoing funding levels seen post-World Wars. Alternatively, an annual investment increase of $2.2 billion to $3.8 billion could also mitigate productivity slowdowns caused by climate change.
Senior author Ariel Ortiz-Bobea highlights the importance of understanding climate change’s impact on agricultural productivity. He pointed out that while significant growth in research investment is required, such efforts have historical precedent. The current public investment in agricultural research stands at approximately $5 billion, which has stagnated since the early 2000s, necessitating urgent action to bolster funding.
Researchers aggregated 50 years of data on temperature fluctuations and agricultural outputs to assess climate change impacts. Their findings indicated that a temperature rise of 3 degrees Celsius could lead to a productivity drop of over 10%. The study also established the potential returns on investment from research funding, proposing a total funding requirement of between $208 billion to $434 billion by 2050 to maintain agricultural productivity.
Ortiz-Bobea advocates for a systematic approach to public spending on research, citing that the high return on investment from agricultural research is well-documented. He warns that neglecting research may lead to greater reliance on government bailouts, increased agricultural land use, and environmental degradation.
The distinction between public and private research and development is also emphasized, where public funding is viewed as beneficial for farmers without the accompanying cost burdens that private innovations often impose. Ortiz-Bobea argues that public sector research targets the social returns that private ventures may overlook, asserting the need for a commitment to addressing climate challenges in agriculture and improving productivity.
The study underscores a critical juncture for U.S. agriculture, revealing that rising climate challenges necessitate a substantial increase in public research funding. With projections highlighting the importance of consistent investment growth to maintain productivity, the researchers call for decisive action. Addressing agricultural productivity issues not only involves immediate financial commitments but also a long-term vision for sustainable agricultural practices.
