Disaster events are not only becoming more frequent and severe but their impact is also expected to worsen. The year 2023 brought an end to the warmest decade on record, marked by unprecedented extreme weather events and large-scale disasters. These catastrophes were worsened by ongoing conflicts and the COVID-19 pandemic.
A report by the Food and Agriculture Organization titled ‘The Impact of Disaster on Agriculture and Food Security’ found that the frequency of extreme disaster events has risen significantly over the past 50 years. The 1970s saw approximately 100 disaster events per year. In the last 20 years, that number went up to about 400, globally (Chart 1).

According to the EM-DAT database of the Centre for Research on the Epidemiology of Disasters, 2022 witnessed nearly 31,000 deaths and an estimated $223.8 billion in economic losses from disasters, affecting over 185 million people.
Agricultural activities and livelihoods rely heavily on environmental conditions, natural resources, and ecosystems. Globally, the agriculture sector faces growing threats from hazards such as flooding, water scarcity, drought, diminishing agricultural yields, fisheries depletion, loss of biodiversity, and environmental degradation. For instance, in Pakistan, exceptional monsoon rainfalls in 2022 led to nearly $4 billion in damages to the agricultural sector. In the U.S., the National Oceanic and Atmospheric Administration estimated over $21.4 billion in crop and rangeland losses in 2022, with drought and wildfires responsible for most of the crop losses.
Data from 88 Post-Disaster Needs Assessment surveys conducted from 2007 to 2022 in 60 countries indicated that agricultural losses constituted an average of 23% of the overall impact of disasters across all sectors. However, the available data are limited, primarily focusing on low-income countries and major extreme events. A comprehensive global estimate of economic losses across all sectors is unavailable.
PDNAs revealed that more than 65% of losses attributed to drought affected the agricultural sector, while floods, storms, cyclones, and volcanic activities each accounted for roughly 20% (Chart 2).

However, data on loss and damage are not systematically collected or reported. To address this gap, the report used secondary data sources such as EM-DAT and FAOSTAT production data to quantify the impact of disasters on agriculture, with a specific focus on crop and livestock production. Findings indicated that estimated losses in these sub-sectors have been gradually increasing over the past three decades.
The total loss from extreme events over the past 31 years amounted to approximately $3.8 trillion, averaging about $123 billion per year.

Losses across major crop and livestock product groups exhibited increasing trends (Chart 3). Over the past three decades, estimated losses in cereals averaged 69 million tonnes annually. Losses in fruits and vegetables, along with sugar crops, averaged 40 million tonnes each annually. Meats, dairy products, and eggs experienced an estimated loss of 16 million tonnes per year.

The distribution of total losses across regions from 1991 to 2021 also reflected the geographic size of each region. Asia bore the largest share of economic losses (45%), while Africa, Europe, and the Americas displayed similar orders of magnitude. Oceania experienced the lowest total losses (Chart 4).

In absolute terms, high-income countries, lower-middle-income countries, and upper-middle-income countries reported higher losses, while low-income countries and Small Island Developing States experienced lower levels. However, when considering losses relative to agricultural value added, low-income countries suffered losses more than double those of upper-middle-income countries on average (Chart 5).
