Past and future sensitivity of primary production to human modification of the landscape

摘要: [1] Primary production is the basis of food chain for humans and all other animal species on Earth. This study estimates sensitivity global terrestrial net primary (NPP) to both past future human modifications landscape in comparison with decadal-scale interannual variability NPP. Landscape modification has had spatially varying effects NPP, generally within range variability. In future, likely occur predominantly humid tropics large NPP reductions outside Future modification, absence improved land management, be a more significant negative influence than past, which should considered studies investigating biospheric response climate change, enhanced atmospheric carbon dioxide, nutrient deposition, forcing factors
