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 ...
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 ...
Spatial characterization of colonies of the flying fox bat, a carrier of Nipah Virus in Thailand
A major reservoir of Nipah virus is believed to be the flying fox genus Pteropus, a fruit bat distributed
across many of the world’s tropical and sub-tropical areas. The emergence of the virus and its zoonotic transmission
to ...
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 ...
Role of geoinformatics in ensuing global food security with special reference to dryland agroecosystems
Agriculture plays an important role in providing
food security in developing countries. Better agricultural
information is one of the key factors in understanding current
trends and status that determine food security from ...
Tracking the dynamics of paddy rice planting area in 1986–2010 through time series Landsat images and phenology-based algorithms
Agricultural land use change substantially affects climate,water, ecosystems, biodiversity, and humanwelfare. In
recent decades, due to increasing population and food demand and the backdrop of global warming, croplands
have ...
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 ...
Spatial big-data analytics for agricultural intensification and crop diversification in rice fallows
Supply-demand gap of agricultural commodities continues to rise while total arable land area is
not expected to increase significantly in India. Future increases in agricultural production will be
contingent upon agricultural ...
