“Our assessment shows, for the first time, the exact extent and distribution of mangrove forests of the world at 30 meters spatial resolution, the highest resolution ever,” said Dr Chandra Giri from USGS. “This reveals that 75% of the remaining forest is found in just 15 countries, out of which only ~6.9% is protected under [...]

Since 1972, the UNESCO “World Heritage Convention” offers an international canvas for conservation and management that targets areas of high cultural and environmental significance. To support the designation of areas within the 36.000 km2 of New Caledonia coral reefs and lagoons as a World Heritage Site, the natural value and diversity of the proposed zones [...]

Coral reef fisheries are critical for food security and as a source of income in developing and developed countries, but they are collapsing in many areas. Following the emergence and routine availability of commercial very high spatial resolution (0.6–10 m) multispectral satellite images, we reviewed the use of these new high-quality remote sensing data and [...]

This paper examines changes in the surface area of glaciers in the North and South Chuya Ridges, Altai Mountains in 1952–2004 and their links with regional climatic variations. The glacier surface areas for 2004 were derived from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) imagery. Data from the World Glacier Inventory (WGI) dating [...]

Reducing uncertainty in climate projections can involve giving less credence to Atmosphere-Ocean General Circulation Models (AOGCMs) for which the simulated future climate is judged to be unreliable. Reliability is commonly assessed by comparing AOGCM output with observations. A desirable property of any AOGCM skill score is that resulting AOGCM-performance rankings should show some consistency when [...]

Geothermal resources exist on the Pyramid Lake Paiute Tribal Lands (PLPTL) in northwestern Nevada. We compiled numerous indicators of these resources into a geographic information system along with concurrent investigative results. This effort required acquisition and analysis of spaceborne multispectral and airborne hyperspectral remote sensing data for early-stage geothermal exploration. We identified minerals such as [...]

Although recent biodiversity loss has been compared with cataclysmic mass extinctions, we still possess few indicators that can assess the extent or location of biodiversity loss on a global scale. The Convention on Biological Diversity (CBD) has mandated development of indicators that can meet the needs of monitoring biodiversity by 2010. To date, many indicators [...]
