Book (series)Technical studyThe impact of climate variability and extremes on agriculture and food security - An analysis of the evidence and case studies
Background paper for The State of Food Security and Nutrition in the World 2018
2020Also available in:
No results found.Global climate studies show that not only temperatures are increasing and precipitation levels are becoming more varied, all projections indicate these trends will continue. It is therefore imperative that we understand changes in climate over agricultural areas and their impacts on agriculture production and food security. This study presents new analysis on the impact of changing climate on agriculture and food security, by examining the evidence on recent climate variability and extremes over agricultural areas and the impact of these on agriculture and food security. It shows that more countries are exposed to increasing climate variability and extremes and the frequency (the number of years exposed in a five-year period) and intensity (the number of types of climate extremes in a five-year period) of exposure over agricultural areas have increased. The findings of this study are compelling and bring urgency to the fact that climate variability and extremes are proliferating and intensifying and are contributing to a rise in global hunger. The world’s 2.5 billion small-scale farmers, herders, fishers, and forest-dependent people, who derive their food and income from renewable natural resources, are most at risk and affected. Actions to strengthen the resilience of livelihoods and food systems to climate variability and extremes urgently need to be scaled up and accelerated. -
Book (series)YearbookWorld Food and Agriculture – Statistical Yearbook 2024 2024
Also available in:
No results found.The Statistical Yearbook 2024 offers a synthesis of the major factors at play in the global food and agricultural landscape. Statistics are presented in four thematic chapters, covering the economic importance of agricultural activities, inputs, outputs and factors of production, their implications for food security and nutrition and their impacts on the environment. The Yearbook is meant to constitute a primary tool for policymakers, researchers and analysts, as well as the general public interested in the past, present and future path of food and agriculture. -
BookletCorporate general interestGreenhouse gas emissions from agrifood systems
Global, regional and country trends, 2000–2022
2024Also available in:
No results found.Agrifood systems account for about one-third of total anthropogenic greenhouse gas emissions. They are generated within the farm gate, from crop and livestock production activities; by land-use change, caused by deforestation, biomass fires and peatland degradation processes often linked to land clearance for agriculture; and in pre- and post-production processes, comprising the supply chain including food manufacturing, retail, household consumption and food disposal. According to the latest data, global agrifood systems emissions reached 16.2 billion tonnes of carbon dioxide equivalent (Gt CO2eq) in 2022, virtually unchanged from 2021, and representing an increase of 10 percent since 2000.
