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 ...
Estimating Agricultural Crop Types and Fallow Lands Using Multi Temporal Sentinel-2A Imageries
Meeting the food and nutritional demands of ever growing human population will cause immense pressure on agricultural lands and natural resource bases across the world. This challenge can be met only by proper land and ...
ICARDA Efforts to Promote In Situ/On-farm Conservation of Dryland Agrobiodiversity
Dryland biodiversity has only recently got due attention because of its potential to contribute in overcoming the effects of global challenges caused by land degradation and and climate change (FAO, 1989). More particularly, ...
Changes in barley (Hordeum vulgare L. subsp. vulgare) genetic diversity and structure in Jordan over a period of 31 years
In many regions of the world, the cultivation of landraces is still common, in particular in centres of crop diversity. Significant effort has been put into ex situ conservation of landraces but limited data exist on the ...
Mapping Cropland Abandonment in the Aral Sea Basin with MODIS Time Series
Cropland abandonment is globally widespread and has strong repercussions for regional
food security and the environment. Statistics suggest that one of the hotspots of abandoned cropland
is located in the drylands of the ...
Assessment of the agricultural production with satellite earth observation – A case study in Fergana Valley, Uzbekistan
Assessment of the agricultural production with satellite earth observation – A case study in Fergana Valley, Uzbekistan (will updated once final manuscript is published
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 ...
Regional-scale monitoring of cropland intensity and productivity with multi-source satellite image time series
In the context of growing populations and limited resources, the sustainable intensification of agricultural production is of great importance to achieve food security. As the need to support management at a range of spatial ...
A 50-m Forest Cover Map in Southeast Asia from ALOS/ PALSAR and Its Application on Forest Fragmentation Assessment
Southeast Asia experienced higher rates of deforestation than other continents in the 1990s and still was a hotspot of forest
change in the 2000s. Biodiversity conservation planning and accurate estimation of forest carbon ...
Quantification of Agricultural Water Productivity at Field Scale and Its Implication in On-Farm Water Management
The Kingdom of Saudi Arabia (KSA) is under
extreme water shortage conditions. About 80 % of water in
KSA is utilized by the agricultural sector; therefore, proper
management of irrigation water is required to produce ...
