Extreme weather events are increasingly damaging crops worldwide, as highlighted by a Carbon Brief analysis which documented 100 instances of crop destruction from 2023-2024. This trend is attributed to climate change, resulting in severe impacts on agricultural production and raising concerns among experts. Effective adaptation strategies are needed, but financial and operational barriers challenge their implementation, particularly for small-scale farmers.
Extreme weather conditions are increasingly damaging crops globally, with events such as floods and droughts noted from Tanzania to Vietnam and Cambodia, affecting various crops including corn and coffee. Carbon Brief compiled this data into a map that visualizes 100 instances of crop loss from January 2023 to December 2024 based on extensive media analyses and reports from the UN Food and Agriculture Organization. These occurrences highlight a concerning trend: severe weather events have spiked since at least the mid-20th century, disrupting traditional food production zones.
The Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6) emphasizes that extreme weather will likely push food production beyond sustainable limits. Experts express alarm at the impact of recurring extreme weather events on agriculture around the globe, noting both immediate crop failures and long-term agricultural decline. Historical examples, like a 2012 typhoon that devastated the banana industry in the Philippines, illustrate the lasting consequences of such events.
Changing climates necessitate adjustments in agricultural practices; for instance, apple cultivation in Nepal has risen to higher altitudes due to new climatic conditions. Experts assert that climate change interacts with other risks like trade disruptions, affecting food production without predictable patterns. A comment from Prof. Andy Challinor signals that these interconnected risks often lead to unexpected outcomes and that systemic resilience is lacking in current food systems, exacerbating vulnerability to extreme weather.
Carbon Brief’s analysis categorizes a range of crops, focusing on the influences of extreme weather on food production. Human-induced climate change amplifies these weather extremes, threatening agricultural yield consistency. Some events have been linked to climate change through attribution studies; for example, floods in Brazil spurred by El Niño and climate alteration caused severe soybean crop losses.
The El Niño phenomenon has been identified as a critical factor in recent droughts, notably in southern Africa, which devastated maize production in Zimbabwe. The World Meteorological Organization reported a combined impact of El Niño and climate change in 2023, leading to multiple agricultural crises in Latin America, where wildfires wreaked havoc on vineyards in Chile and drought conditions hampered soybean and corn output in Argentina.
While the focus has been predominantly on crops, livestock is equally affected. For example, a severe winter event in Mongolia led to mass livestock deaths, highlighting the consequences of occurrence overlap like dzuds, which are exacerbated by ongoing climate change. Moreover, extreme heat has resulted in reduced milk yields in certain regions. As temperatures rise, pests and diseases are also more likely to proliferate, further threatening agricultural productivity.
Contrarily, some crops might benefit from warmer temperatures; for instance, conditions may become more favorable for growing durians and mangoes in Malaysia. Research indicates potential increases in soybean, chickpea, and grape cultivation in previously unsuitable UK climates. The IPCC anticipates significant adverse impacts on food systems under a 2°C rise in global temperatures, suggesting that agricultural lands will become less suitable for cultivation.
The report warns of multi-breadbasket failures where simultaneous extreme weather events threaten crop yields across various regions. Though farmers can adapt to changing conditions, there are considerable barriers. Prof. Elena Piedra-Bonilla expresses concern for small-scale farmers who lack the resources and capacity to implement adaptive practices effectively. She underscores the urgency of adaptation efforts for vulnerable communities, especially in lower-emission countries facing severe weather shocks.
The AR6 report notes various practical adaptation strategies, including sustainable resource management and enhancing diverse crop species. However, financial constraints remain a significant challenge, with much more investment needed for robust agricultural adaptation measures. With only 4% of global climate finance dedicated to agrifood systems in recent years, resources for crop insurance and disaster relief also face limitations, contributing to vulnerabilities within the sector.
Ultimately, while climate change will continually challenge agricultural systems, the potential for solutions exists. Dr. Monica Ortiz points to the viability of drought-resistant crops as a means of bolstering resilience among farmers. Nevertheless, ensuring the successful implementation of innovative practices requires aligning research with on-ground realities and fostering supportive agricultural environments.
Extreme weather is increasingly threatening global crops due to climate change, leading to significant agricultural losses. The interconnectedness of various climate factors complicates predictive modeling and exacerbates the impacts on food production. Adaptation strategies are critical, yet barriers remain, especially for small-scale farmers. Future resilience efforts will require systemic changes to agriculture, emphasizing the need for investment in adaptation practices and technological advancements.
