With the support of the German Agency for International Cooperation (GIZ), Representatives of the International Innovation Center of the Aral Sea basin (IICAS), the Research Institute of Irrigation and Water Problems, the Cadastre Agency of the Republic of Karakalpakstan, the Reclamation Expedition under the Ministry of Water Resources and the Ministry of Water Resources of the Republic of Karakalpakstan carried out scientific research practical expedition to the main collector “Akchadarya” (Kytai Jargan). The purpose of this scientific and practical expedition is to study the state, collect water samples at different points and calculate water flow at PK0 of the Akchadarya main collector and monitor the state of lake systems and wetlands formed from water using innovative methods, such as determining GPS coordinates in combination with space observation data. Also, specialists studied the possibilities of using collector waters to increase the natural productivity of biological resources, to mitigate the environmental situation in the Aral Sea region. For information: Between 2004 and 2013, a project called “South Karakalpakstan Drainage Project” was implemented. This project was implemented in accordance with the resolution of the Cabinet of Ministers of the Republic of Uzbekistan dated January 26, 2004 No. 37 “On measures to implement the project “Drainage Project of Uzbekistan. Project for drainage from Southern Karakalpakstan”. The project was financed by the World Bank, on the basis of loan and credit agreements that were signed with the IBRD/IDA on February 5, 2004 (International Bank for Reconstruction and Development/International Development Association). The goal of the project was to increase the productivity of irrigated agriculture, provide employment in Karakalpakstan by restoring irrigation and drainage infrastructure in the area, improve water quality in the Amu Darya River by eliminating drainage discharges and improving the quality of wetlands along the South Karakalpak main sewer. Within the framework of this project, the cleaning and reconstruction of collector and drainage networks with a length of 2145.4 km was carried out, including the construction of the Akchadarya collector at 193.4 km with a throughput capacity of 25 m3/s.)
