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 ...
Modeling gross primary production of paddy rice cropland through analyses of data from CO2 eddy flux tower sites and MODIS images
Accurate information on the gross primary production (GPP) of paddy rice cropland is critical for assessing and monitoring rice growing conditions. The eddy co-variance technique was used to measure net ecosystem ex- change ...
Tracking the dynamics of paddy rice planting areas through analysis of time series Landsat images
Paddy rice agriculture affects food supply, climate, water, biodiversity, and ecosystems. It varies substantially over time and space, for example, continuous expansion in northeastern China and rapid loss in southern China ...
Mapping paddy rice planting areas through time series analysis of MODIS land surface temperature and vegetation index data
management of water resources, and estimation of greenhouse gas (methane) emissions. Paddy rice agriculture
has expanded rapidly in northeastern China in the last decade, but there are no updated maps of
paddy rice fields ...
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 ...
Spatial BigData Analytics for intensification of pulses
Supply-demand gap of agricultural commodities continues to rise while total arable land area is not expected to increase significantly. Future increases in agricultural production, particularly pulses, will be contingent ...
Quantification of cropping pattern and productivity of agro-ecosystems in Central Asia
Agricultural production systems in Central Asia have been evolving in response to changes in climate, land use and policies. The cropping pattern and productivities of irrigated and rainfed agro-ecosystems as well as grazing ...
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 ...
