In May 2011, the OECD launched its Green Growth Strategy. It is a strategy for governments that contains recommendations on policy instruments and tools for achieving economic growth in line with the sustainable use of natural resources and a measurement framework for progress towards these goals. As set out in one of the strategy's central reports, Towards Green Growth, OECD governments share the objective of introducing green growth policies that will achieve efficiencies in the use of natural resources and reduce environmental problems whilst expanding economic growth and job creation in new directions. These policies are critical to addressing what may otherwise become irreversible problems of increased water scarcity, resource bottlenecks, air and water pollution, climate change and biodiversity loss. Clean-tech development in the Negev is also of strategic importance to regional development. Clean-tech activity is one of the most important opportunities for the economic development of the Negev region, because of the region's existing assets and potential for growth in this area tied to the high global growth trajectory expected for this industry in the next two decades.
