Under the Paris Agreement on climate change, all parties are required to define and communicate their “nationally determined contributions” (NDCs), the efforts that they plan to undertake to reduce national greenhouse gas emissions and adapt to the impacts of climate change. To ensure they are sufficiently ambitious, the targets and commitments set out by countries in 2015 need updating every five years. This project represented FAO’s response to specific countries’ requests for support to conduct the first revision of NDCs in 2020. The overarching objective was to improve countries’ strategies and tools to reduce their emissions and improve adaptation in the agriculture, forestry and other land use (AFOLU) sector, addressing existing gaps in AFOLU components and resulting in more ambitious commitments and strategies.
