Only 4% of Climate Finance Reaches Agriculture Despite Sector Facing 6% Yield Loss Per Degree of Warming

Only around 4 percent of global public climate finance is directed toward building resilience in agriculture and food systems, despite the sector being on the front lines of climate change and accounting for roughly one-third of global greenhouse gas emissions, according to a senior Food and Agriculture Organization official. The remarks from Kaveh Zahedi, FAO Assistant Director General and Director of the Office of Climate Change, Biodiversity and Environment, followed publication of a joint WMO and FAO report titled Extreme Heat and Agriculture, which found that extreme heat impacts on agriculture, food systems, ecosystems and human life are increasing rapidly. Zahedi warned that every 1 degree Celsius rise in average global temperatures leads to an estimated 6 percent reduction in yields of key crops, with maize, rice, wheat and soybeans already experiencing declining productivity at a time when they collectively provide more than 60 percent of global calorie intake.

 

The Scale of the Agricultural Climate Finance Gap

 

The 4 percent share of climate finance reaching agriculture represents a profound structural misalignment between where climate vulnerability is concentrated and where capital is being directed. Agriculture and food systems are prominently featured in countries' nationally determined contributions and national adaptation plans, reflecting the recognition at the policy level that the sector is central to both climate adaptation and mitigation. Yet despite this policy prominence, the financing flows have not followed, leaving farmers and food-producing communities systematically underresourced relative to their exposure to climate risk.

Zahedi said the estimated $1.3 trillion required annually to transform agriculture and food systems cannot be covered through climate finance alone, indicating that the gap requires structural reform of both public and private capital flows into the sector. The combination of a massive absolute funding requirement and a historically tiny share of existing climate finance creates one of the starkest examples of misalignment in the global climate investment landscape. Closing even a portion of this gap would require a fundamental reorientation of both multilateral climate funds and development finance institution priorities toward agricultural resilience.

Extreme Heat and the Food System Crisis

 

The joint WMO and FAO report warns that some regions could experience as many as 250 days per year that are too hot to work outdoors, threatening not only crop yields but the livelihoods of hundreds of millions of agricultural workers and small-scale farmers. Heat stress reduces not only the quantity but also the nutritional quality of key staple crops, compounding the food security implications of climate change beyond simple caloric supply. The combination of declining yields across the world's most important staple crops and rising extreme heat frequency creates compounding risks for global food security that extend well beyond individual farming communities.

Zahedi emphasised that farmers are at the centre of the crisis and that their preparedness is essential for ensuring future food security. He argued that multi-hazard early warning systems are among the smartest investments available for protecting farmers and food security from extreme heat, noting that farmers cannot prepare for what they do not know is coming. Despite disparities in internet and mobile phone access across vulnerable agricultural regions, early warning systems can reach farmers through alternative channels including SMS alerts, community radio and local announcements, with the key being that information arrives in a timely and effective manner regardless of the delivery mechanism.

 

The Critical Role of Actionable Guidance

 

Zahedi stressed that early warning systems must be paired with practical, actionable guidance rather than simply delivering temperature forecasts. He said farmers need specific advice on what they can actually do in response to extreme heat, including protecting soil moisture through mulching, storing water, shifting irrigation to cooler hours and using netting to shade crops. The distinction between passive warning and active guidance reflects a broader understanding of how climate information translates into resilience at the farm level, where abstract forecasts must be converted into concrete decisions about planting, irrigation, harvesting and input management.

This emphasis on practical guidance alongside early warning infrastructure highlights the need for extension services, agricultural advisory networks and community-based knowledge transfer to accompany technological investments in monitoring and forecasting systems. Many of the most climate-vulnerable farming communities lack access to the agronomic expertise needed to interpret climate information and adapt their practices accordingly, creating a human capacity gap that technology alone cannot bridge. Addressing this requires sustained investment in rural advisory services alongside digital and communication infrastructure.

COP31 and the Agriculture-Climate Nexus

 

Zahedi identified COP31, which Türkiye will host in November, as an important platform for advancing the climate and agriculture agenda, noting that FAO has already held encouraging conversations with the Turkish presidency about the role food systems can play in confronting climate challenges. He said food systems and agriculture have become increasingly central over the last five to six climate summits and can no longer be treated as secondary issues, with momentum he hopes to maintain through the COP31 process. Türkiye's position as a major agricultural country has strengthened awareness of the agriculture-climate relationship at the national level, providing a constructive foundation for hosting discussions on food system transformation.

Zahedi argued that without agriculture, the promises of the Paris Agreement cannot be delivered on either adaptation and resilience or on mitigation grounds. The one-third of global emissions attributable to agri-food systems means that no credible net-zero pathway can succeed without transforming food production, processing, distribution and consumption. At the same time, the sector's frontline exposure to climate impacts makes agricultural resilience one of the most direct forms of climate adaptation available to the world's most vulnerable communities.

 

Outlook for Agricultural Climate Finance

 

The combination of a 4 percent financing share, a $1.3 trillion annual transformation requirement and accelerating heat-related risks creates an urgent case for a fundamental reorientation of climate finance toward agriculture. Whether COP31 and the broader climate finance negotiations surrounding the New Collective Quantified Goal can deliver meaningful increases in agricultural adaptation finance will depend on political will among donor governments and the effectiveness of developing country advocacy for this historically underfunded sector. The FAO's engagement with the Turkish COP31 presidency suggests a deliberate strategy to elevate food systems on the climate summit agenda.

Sustained progress would require not only increased financing flows but also better measurement frameworks for agricultural climate finance, stronger targeting of the most vulnerable farming communities and deeper integration of food system considerations into national climate strategies and investment plans. The trajectory of extreme heat impacts on agriculture over the coming decade will make the consequences of continued underinvestment increasingly visible to policymakers, investors and the public. Rising awareness of the food security implications of climate change may ultimately provide the political pressure needed to redirect a meaningfully larger share of climate finance toward the sector most in need of it.
