“Widespread degradation and deepening scarcity of land and water resources have placed a number of key food production systems around the globe at risk, posing a profound challenge to the task of feeding a world population expected to reach 9 billion people by 2050, according to a new FAO report. The State of the World’s Land and Water Resources for Food and Agriculture (SOLAW) notes that while the last 50 years witnessed a notable increase in food production, “in too many places, achievements have been associated with management practices that have degraded the land and water systems upon which food production depends.” Today a number of those systems “face the risk of progressive breakdown of their productive capacity under a combination of excessive demographic pressure and unsustainable agriculture use and practices,” the report says. No region is immune: systems at risk can be found around the globe, from the highlands of the Andes to the steppes of Central Asia, from Australia’s Murray-Darling river basin to the central United States.”
