Comparison of four EVI-based models for estimating gross primary production of maize and soybean croplands and tallgrass prairie under severe drought
Accurate estimation of gross primary production (GPP) is critical for understanding ecosystem response to climate
variability and change. Satellite-based diagnostic models, which use satellite images and/or climate data
as ...
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 ...
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 ...
Satellite-based observation and modeling of grasslands and croplands in dry areas
Grasslands and croplands in dry areas (semi-arid and arid regions) are sensitive to changes in
climate and land use. Accurate and updated information of grasslands and croplands are
important for the studies of food security ...
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 ...
