TAILIEUCHUNG - DRYLANDS, PEOPLE,AND ECOSYSTEM GOODS AND SERVICES: A Web-Based Geospatial Analysis (PDF Version)

If the UK environmental employment baseline level grows in line with projected annual growth rates (see Table 3 below), then, potentially, an additional 400,000 jobs could be created over the next eight years ‐ representing a 45% increase on today’s level. This is a rough estimate based on the growth in market value, where employment levels are calculated on a pro rata basis. Some of this growth in employment might be due to displacement activity, as green goods and services become more acceptable than the alternatives, such as a shift from manufacturing traditional doors/windows to heat and energy efficient ones, or from carbon‐based fuels such as coal to renewable energies such as wind. However the majority of the growth in employment, particularly in the Renewable Energy industries, would represent additional economic growth to 2015. . | WORLD RESOURCES INSTITUTE Drylands People and Ecosystem Goods and Services A Web-Based Geospatial Analysis PDF Version Robin P. White Janet Nackoney Introduction This web-based analysis takes advantage of the power of geospatial technologies to examine the world s drylands. We consider drylands from the perspective of human livelihoods examining how these livelihoods are integrated with dryland ecosystem goods and services. Our presentation is map-rich using combinations of remotely-sensed data and computer-based data management systems GIS . Where global data are not available we use regional and national studies. We focus on a selected set of dryland goods and services forage and livestock food production biodiversity conservation freshwater carbon storage energy production and tourism and recreation. The final two sections examine drylands and trade and drylands and the impacts of human activities. Each subject area is generally presented with a brief overview map map description and list of sources. Links are provided to associated data tables and text boxes. All maps are shown in Geographic projection. Definition of Drylands We define drylands according to the definition provided by the United Nations Convention to Combat Desertification CCD . The CCD uses the ratio of mean annual precipitation to mean annual potential evapotranspiration to identify drylands of the world. Potential evapotranspiration is the amount of moisture that if it were available would be removed from a given land area by evaporation and transpiration. Map 1.

Drylands include arid semi-arid and dry sub-humid areas other than polar and sub-polar regions in which
