Crop production and irrigation water requirements under climate change 2004-2050

Victor Nechifor & Matthew Winning
Increases in CO2 atmospheric concentrations are expected to lead to multiple and possibly opposing effects over crop performance. The paper uses a global economic model (RESCU-Water) to analyse the impacts of changes in climatic conditions and CO2 fertilisation on crop output and on the pressure over water resources coming from irrigation. RESCU-Water is built on a Computable General Equilibrium Framework and distinguishes between the rainfed and irrigated production of eight crop classes. Irrigation is introduced...
