Assessing the micro-level spatial drought vulnerability in South Central India can assist with coping measures for farmers and others in the region. This study used various thematic maps to derive a village-level drought vulnerability map, which will be useful to drought management and preparedness in the future.
A project on the use of Gravity Recovery and Climate Experiment (GRACE) data to estimate changes in groundwater storage in the Central Valley aquifer in collaboration with the California Department of Water Resources (DWR). This work has the potential to improve CaliforniaÛªs groundwater resource management and the use of existing hydrologic models for the Central Valley.
Will an effective mechanism be put in place to detect the onset of drought in AfricaÛªs Lake Chad Basin? What needs to be done to minimize adverse effects of drought in the basin? In this essay, scientific perspectives are applied to explain and compare the complex nature of the current drought in Somalia and the Lake Chad Basin.
Limited water resource availability and efficient water management are major global challenges facing policymakers in many countries of the world, and South Africa is no exception. Advanced satellite technologies offer new opportunities to address these issues. In 2010, the GrapeLook project was initiated, providing information on crop water, growth and nitrogen status during the growth season using satellite data. The first demonstration year provided users with a deeper insight into the temporal and spatial processes in vineyards to improve water productivity.
Coastal wetlands in the Mediterranean have undergone considerable land use and land cover changes in recent decades, by way of urban growth and increasing tourism infrastructure. The GlobWetland-II project makes use of the 35 years of Landsat archives for a basic identification and delineation of wetlands during 1975, 1990, and 2005. The authors present results of wetland identification and delineation mapping from 1975 to 2002, for the test sites of the Menderes Delta and GÌ_llÌ_k Bay.
Sustainable access to safe drinking water is a public health issue directly linked to the economy in Haiti and around the world. This research applies remote-sensing techniques to data from ASTER satellite imagery to produce maps useful for placing community-level water-filtration installation systems in Port au Prince and surrounding areas.
Earthzine is soliciting articles of 800-3,000 words for its Fourth Quarter Theme Issue on Water Availability. We seek contributions addressing current issues, techniques and applications of Earth information for measuring water, the social benefits of monitoring water and the humanitarian implications of water availability.
