Satellite evidence on the trade-offs of the food-water–air quality nexus over the breadbasket of India
Access to food, water, and good air quality is indispensable for human life, as reflected in various United Nations Sustainable Development Goals (SDGs); however, pursuing food security may pose threats to water security ...
Spatiotemporal patterns of paddy rice croplands in China and India from 2000 to 2015
Due to rapid population growth and urbanization, paddy rice agriculture is experiencing substantial changes in the spatiotemporal pattern of planting areas in the two most populous countries—China and India—where food ...
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 ...
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 ...
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 ...
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 ...
Mapping paddy rice planting area in northeastern Asia with Landsat 8 images, phenology-based algorithm and Google Earth Engine
Area and spatial distribution information of paddy rice are important for understanding of food security, water use, greenhouse gas emission, and disease transmission. Due to climatic warming and increasing food demand, ...
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 ...
