Understanding patterns of vegetation change and related climatic factors are critical, especially in light of future climate change projections that could profoundly alter vegetation patterns and processes. A recent NASA Applied Sciences DEVELOP project focused on the use of the Landsat-5 TM satellite images to assess the general vegetation distribution pattern and areas of vegetation change along the California coast from 1985-2010.
Remote sensing has emerged as an important tool to help identify habitats most in need of conservation. But applying remotely sensed data has its challenges. To solve these problems, the Joint Research Center of the European Commission has developed the Digital Observatory for Protected Areas (DOPA) to help assess, monitor and forecast the status and environmental pressures faced in protected areas.
Will an effective mechanism be put in place to detect the onset of drought in Africa’s 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.
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.
Scientists, citizens, non-governmental organizations and governments need to find a shared language. As the language of the market system, economic valuation can offer common communication that creates a bridge between different fields of work. A synthesis called TEEB outlines an approach to environmental valuation and offers recommendations on how decision-makers can use the plan as an informative tool.
