Agricultural Production

The global food system is uniquely vulnerable to climate impacts, making adaptation of paramount importance. While contributing roughly one-third of total anthropogenic emissions, food systems around the world fortunately also hold immense potential for mitigation through improved practices and land use. A new article published today in Science emphasizes the critical role of agrifood value chains (AVCs) in supporting both adaptation and mitigation at the farm level.

Climate change is increasing the frequency of adverse weather events and reducing agricultural productivity, particularly in warmer regions of the world (Ortiz-Bobea et al 2021). Smallholder farming households in developing countries depend on agriculture for their livelihoods and spend a larger proportion of their income on food,  making them the most vulnerable to harvest failures  (Hallegatte et al 2020).

In September, the FAO Food Price Index saw the largest month-on-month increase since May 2022, rising 3 percent from August. While the Index is 2 percent higher than its September 2023 level, it remains over 22 percent below its March 2022 peak.

The complex challenge of increasing food production while mitigating carbon dioxide emissions, building resilience to climate change, and reducing the burden of agriculture on natural resources requires innovative approaches. Promising strategies include increasing access to mechanization and adopting modern fertilization processes that contribute to climate change adaptation efforts, or the use of improved seeds.

With global temperatures already 1.2 degrees Celsius above pre-industrial levels, climate change is having major impacts on agriculture that fall disproportionately on the Global South—from crops, to livestock, to aquaculture. Agricultural systems endure frequent heat waves, flooding, and drought—often all in one season. Climate-related extreme weather events such as intense rainstorms pose a serious threat to crops.
