Sensitivity of vegetation indices and gross primary production of tallgrass prairie to severe drought
Drought affects vegetation photosynthesis and growth.Many studies have used the normalized difference vegetation
index (NDVI), which is calculated as the normalized ratio between near infrared and red spectral bands ...
Exacerbated degradation and desertification of grassland in Central Asia
Grassland desertification is a complex process, including both state conversion (e.g., grasslands to deserts) and
gradual within-state change (e.g., greenness dynamics). Existing studies generally did not separate the ...
Quantification of Land Degradation and Productivity of Agro-Ecosystems under Changing Climate and Land Use
Agro-ecosystems in dry areas are sensitive to changes in climate
and land use. The productivities of these agro-ecosystems are
highly variable in both spatial and temporal scales. Accurate and
up-to-date information on ...
Exacerbated grassland degradation and desertification in Central Asia during 2000–2014
Grassland degradation and desertification is a complex process, including both
state conversion (e.g., grasslands to deserts) and gradual within-state change (e.g., greenness
dynamics). Existing studies hardly separated ...
Quantification of Land Degradation and Productivity of Agroecosystems under Changing Climate and Land Use
Agro-ecosystems in dry areas are sensitive to changes in climate and land use. The productivities of these agro-ecosystems are highly variable in both spatial and temporal scales. Accurate and up-to-date information on ...
Improving Assessment and Monitoring of Droughts in Grasslands
Grasslands in the Southern Great Plains of the United States have
experienced various degrees of droughts over years and substantial
economic losses occurred to many ranchers under severe drought
conditions. Since 2013 we ...
