Climate-smart agriculture (CSA) is an integrated approach to managing land, crops, livestock, forests, and fisheries to help adapt agricultural methods to the effects of climate change and, where possible, counteract it by reducing greenhouse gas emissions. CSA aims to simultaneously achieve three outcomes: increased productivity, enhanced resilience, and reduced emissions. The approach proposes more integrated approaches to the closely linked challenges of food security, development, and climate change adaptation/mitigation, to enable countries to identify options with maximum benefits and those where trade-offs need management. CSA does not define any new farming practices but includes many practices that farmers already use, such as conservation tillage, cover cropping, nutrient management, and agroforestry. Steering these practices toward production, adaptation, and mitigation goals is what makes them “Climate-Smart” . The World Bank, the UN, and the US have launched the Agriculture Innovation Mission for Climate (AIM for Climate/AIM4C), a 5-year initiative to 2025, to rally around climate-smart agriculture and food system innovations. The initiative has attracted some 500 government and non-government organizations around the world and about 10 billion USD from governments and 3 billion USD from other sources.
