World food production is at risk from farming methods that have degraded soils, parched aquifers, polluted waters, and caused the loss of animal and plant species, according to a new report by the International Food Policy Research Institute (IFPRI) and the World Resources Institute (WRI). Soil degradation has dramatically reduced crop productivity, with severe consequences likely for poor, heavily populated countries. Agricultural lands face an enormous challenge to provide food for the expected population surge of 1.5 billion people over the next 20 years.
