Food Security and Agriculture

Higher temperatures, changes in daytime and nighttime temperatures, and shifts in seasons and precipitation patterns can all have a significant impact on agriculture and food security. Direct impacts on agriculture can include less fertile soil, more or different crop pests and livestock diseases, changes in fish stock, and reduced yields. Other sector-related consequences include heat stress for livestock and agricultural workers and damage to greenhouses, storage facilities, and other infrastructure.
All of this could lead to greater food insecurity by reducing nutrition, incomes, and access to markets. Agriculture is also a big contributor to emissions due to excessive use of fertilizers, methane released by rice paddies and livestock, over-tilling soil leading to soil carbon and moisture loss, and above all, the conversion of forests and other ecosystems to agricultural uses.
Some practices like low-till, conservation agriculture, crop rotations, and use of shade trees and cover crops improve resilience and reduce emissions. Other adaptation measures include rainfall capture and providing seasonal weather forecasts to inform planting decisions. Emissions can also be reduced with better land use planning to reduce conversion of forested lands


Low-Emissions Opportunities in Agriculture

USAID and the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) are collaborating to support partner countries on their priorities in the land use sector, including in agriculture.

Learning Agenda for Climate Services in Sub-Saharan Africa

The Learning Agenda on Climate Services in Sub-Saharan Africa encompasses two related efforts featured below that seek to generate and analyze new information, evidence, and learning on the effective and sustainable production, delivery and use of climate information to improve decision-making and outcomes for rural agricultural livelihood.

RALI GHG MRV Harmonization Framework: Agriculture, Forestry, and Other Land Use Sector Guide

Countries around the world have set ambitious targets for reducing greenhouse gas emissions and, as a result, are now pursuing a breadth of mitigation actions across sectors and at all scales. This guide provides instructions on how to apply the Harmonization Framework to mitigation activities within the Agriculture, Forestry, and Other Land Use sector.
