Title : Global consequences of land use
Journal : Science
Comment : Land use has generally been considered a local environmental issue, but it is becoming a force of global importance. Land-use practices have played a role in changing the global carbon cycle and, possibly, the global climate: Since 1850, roughly 35% of anthropogenic CO2 emissions resulted directly from land use. Furthermore, anthropogenic nutrient inputs to the biosphere from fertilizers and atmospheric pollutants now exceed natural sources and have widespread effects on ecosystems.
Examples of land-management strategies with environmental, social, and economic benefits include maintaining and increasing soil organic matter in croplands, which is a key to waterholding capacity, nutrient availability, and carbon sequestration; increasing green space in urban areas.
