This layer is a digital raster graphic of the historic 15-minute USGS topographic map of the Sandisfield, Massachusetts quadrangle. The survey date (ground condition) of the original paper map is 1886. A digital raster graphic (DRG) is a scanned image of a U.S. Geological Survey (USGS) standard series topographic map, including all map collar information. The image inside the map neatline is geo-referenced to the surface of the earth and fit to the Universal Transverse Mercator projection. The horizontal positional accuracy and datum of the DRG matches the accuracy and datum of the source map.

The allocation and use of the water resources of Central Asia is one of the most difficult issues to arise out of the break-up of the Soviet Union. How should the waters of the great Central Asian rivers, the Syr Darya and Amu Darya, be used? To generate much needed hydropower electricity in the mountainous countries in which they arise? Or for irrigation in the energy-rich downstream countries? The aim of this paper is to describe the basic problem and the efforts undertaken both by the Central Asian states and the international community, including the EU, to seek a resolution. It traces recent developments relating to the planned construction of dams, the modification of energy supplies and the periodic issue of increasingly bellicose statements from the capitals of the region. Finally it looks into the challenge for establishing a modern international legal order to govern the region's strategic water resources.

This study aims at assessing the socio-economic and environmental effects of different societal and human development scenarios and climate change in the water-scarce southern and eastern Mediterranean. The study develops a two-stage modelling methodology that includes an econometric analysis for the southern and eastern Mediterranean region as a whole and a detailed, integrated socioecological assessment focusing on Jordan, Syria and Morocco. The results show that water resources will be under increasing stress in future years. In spite of country differences, a future path of sustainable development is possible in the region. Water withdrawals could decrease, preserving renewable water resources and reversing the negative effects on agricultural production and rural society. This, however, requires a combination across the region of technical, managerial, economic, social and institutional changes that together foster a substantive structural change. A balanced implementation of water supply-enhancing and demand-management measures along with improved governance are key to attaining a cost-effective sustainable future in which economic growth, a population increase and trade expansion are compatible with the conservation of water resources.
