One Billion Hungry: Can We Feed the World?
Three new publications investigate proposed solutions to global food insecurity, exploring the potential consequences of liberalising trade, increasing crop yields and introducing biotechnology. The first, written by agricultural scientists Tony Fisher, Derek Byerlee and Greg Edmeades, Crop Yields and Global Food Security, investigates the rate at which crop yields must increase if we are to meet global demand for staple crops by 2050. They explore how such targets might be achieved and what the consequences would be for the environment and natural resources.
Population growth, rising incomes per capita and growing biofuel usage mean we expect demand for staple crop products to increase by 60% between 2010 and 2050. This increase can either be met by expanding land area under agriculture or by increasing the yields of crops grown on current land. With land being in short supply and much potential agricultural land requiring deforestation and natural habitat clearance…
