Dramatic rainfall changes for key crops are expected even with reduced greenhouse gas emissions. In an official side event at SB50, we discuss adaptation measures to respond to these changes.
Rain-fed agriculture currently constitutes 60–95% of farmed land across the developing world. Changing rainfall patterns could have a large impact on agriculture in developing countries. Using over 20 different climate models, researchers have projected how precipitation could be affected by climate change. Model simulations for the four main emission scenarios were used identify the timeline when climate change causes rainfall to deviate significantly from the past, more than it would naturally. This is also called the time of emergence (TOE). This was done for the crop-growing regions of four major crops: wheat, rice, soybean and maize. This event aims to present findings from the study and discuss implications for adaptation planning and action with key stakeholders.
The aim is to start a dialogue on stepping up adaptation for agriculture in response to emerging evidence on rainfall changes for key crops, and to enable countries, international organizations, NGOs, and other agricultural adaptation stakeholders to make evidence-based decisions in response to emerging evidence on rainfall changes.
