This region is on the historical Silk Road, and Turkey part of the Mesopotamia, which means to the land between two rivers in Latin, composed of fertile soil and located in a geographical place where the energy resources roads crosses. There have been significant delays in the realization of the South-eastern Anatolia Project (GAP) due to the some external factors. In this study, we discuss political, economic, and strategically importance of the GAP project. In Turkey, background of the GAP is based on the Keban Dam Project in 1930s. GAP was firstly planned as irrigation and hydroelectric power plant (HEPP) projects on the Tigris and Euphrates Rivers. This project was transformed to multipurpose regional development program after 1980s. The Tigris and Euphrates Rivers represent over 28% of the nation’s water supply by rivers, and the economically irrigable areas in the region make up 20% of those for the entry country.

OLCAY UÈ NVER President, Republic of Turkey Prime Ministry Southeastern A natolia Project Regional D evelopment Administration, UgÏ ur Mumcu’nun SokagÏ õ 59, G.O .P., 06700, Ankara, Turkey ABSTRACT The recognition of the great water potential of the Euphrates and Tigris Rivers in south-east Turkey led to plans for their sustainable development for irrigation and hydropower generation and to control ¯ oods and droughts. This integrated socio- economic developmentproject, called the Southeastern Anatolia Project (GAP), is one of the largest of its kind in the world. The water resources development programme includes 22 dams, 19 hydropower plants and the irrigation network for 1.7 million ha of land. The US$32 billion project comprises not only water resources development projects, but also investments in all development-relatedsectors. Pre-project Conditions Area and Population The GAP project area lies in south-eastern Turkey (Figure 1), covering nine Provinces (Adõ yaman, Batman, Diyarbakõ r, Gaziantep, Kilis, Mardin, Siirt, SË anlõ urfa, SË õ rnak), corresponding to approximately 10% of the country’s total population as well as its surface area. The project area includes watersheds of the lower Euphrates and Tigris rivers and the upper Mesopotamian plains. The total surface area is 75 000 km2, of which 42.2% is cultivated (36% rain-fed), 33.3% pastures, and 20.5% forest and bush. Average gradient over 94% of the total surface area is less than 12%, which is the threshold of cultivability. Salinity and alkalinity problems are minimal, and most of the soil has good drainage conditions.

It is thus desirable that this doctoral thesis is read in conjunction with the licentiate thesis to ensure continuity and a better perspective on the overall analysis of the environmental sustainability of water projects. The licentiate thesis focused on the approaches to environmental sustainability of water management in terms of a case study for Mexico. It was the first ever comprehensive analysis of the environmental policies of the water sector in Mexico, as well as an in-depth analysis of all the environmental impact assessment reports that have been conducted in the country. It is important to note that no other analysis of the environmental assessments studies of any other sector of the country is available at present. This thesis already has generated considerable interest for conducting similar comprehensive in-depth analyses for the water sector of other Latin American countries.
