Preliminary Integrated River Basin Plan (PIRBP) 3 EXECUTIVE SUMMARY This Integrated River Basin Plan for the Alazani River was prepared by the “Alazani Consortium” consisting of a specially selected team of technical experts from ORIGO Consulting, a Georgian based consultancy firm; with Little Town, a Georgian NGO; and Nature Protection Society, an Azerbaijan NGO, including independent experts. This plan was prepared within the framework of the “Water Management in the South Caucasus” Project, funded by the U.S. Agency for International Development (USAID), and implemented by Development Alternatives, Inc (DAI). The consortium started the implementation of the Integrated River Basin Planning in early January 2002. The final plan was prepared in September 2002. The principal objective of this work was to demonstrate the process of integrated river basin planning (IRBP) at the local level, and to focus on capacity building in the region. The plan was prepared by implementing the following tasks: 1. Development of stakeholders participation; 2. Preparation of an inventory of water uses; 3. Assessment of issues; 4. Preparation of a public awareness campaign; 5. Formulation of a preliminary integrated river basin plan; 6. Identification of pilot projects; and 7. Preparation of a final integrated river basin plan (IRBP). The IRBP was developed for the Alazani River Basin pilot area. The Alazani River is one of the major tributaries of the Kura River and is created by the junction of two mountain rivers, Tsiplovaniskhevi and Samkuristskali, which flow from the southern slopes of the Main Caucasus Mountain Range. The highest gauging station on the Alazani River is at elev. 2200 m., above mean sea level, and the low end of the river is at about 200 m., above mean sea level. The river crosses an inter-mountainous depression, streams along the Georgian-Azerbaijan border and then flows into Mingachavir Reservoir in Azerbaijan. There are 11 administrative districts in the region, seven in Georgia: Telavi, Gurjaani, Akhmeta, Kvareli, Signagi, Lagodekhi, Dedoplistskaro; and four in Azerbaijan: Kakh, Balaken, Zagatala, Sheki. Agriculture is the main economic activity within the basin. Most of the agricultural lands in the basin are irrigated, while some areas in the Georgian part of the basin are also drained. Hence, irrigation water use is one of the major water uses for the basin. The usage for drinking water is also significant. However, ground waters, which are quite abundant in the region, are also used for drinking water. The waters of the Alazani Basin are also used for hydropower generation and recreation, since many of the rivers have high hydropower potential and the basin is rich in flora and fauna, and supports valuable ecosystems.
