Research studies project report ; no. NR-09-02 Submitted in partial fulfillment of the requirements for the degree of Master of Science in Natural Resources Management, School of Environment, Resource and Development Research Studies Project Report (M. Sc.) - Asian Institute of Technology, 2009 The territory of Central Asian states that comprises of Kazakhstan, Kyrgyzstan Tajikistan, Turkmenistan and Uzbekistan is a subject of intensive environmental degradation, the most acute of which is the Aral Sea recession, also known as environmental catastrophe of global importance. Shortfalls in irrigated agriculture development coupled with the population growth are the main causes of this catastrophe. Thus, the "systematically" erroneous agrarian development during last 30 years resulted in degradation of the Aral Sea. Economic development strategies led to the ecological catastrophe - drying out of the Aral Sea. That has led to severe ecosystems degradation, worsened the population health, reduction in the agriculture effectiveness, increase of salinity level and land resources degradation in the region. The transfer of the salts and dust from the dried bottom of the Sea can also lead to dangerous consequences. About 75 million tons of salts and dust are transferred by winds to hundreds of kilometers to the surrounding areas annually. In this regard, this study examines the impact of the drying up of the Aral Sea on land degradation and its implication on agricultural production in Uzbekistan. The study revealed that the Aral Sea dry out led to increase the salinity level in the country by 7%. This in turn resulted in situation when annually around 20 thousand hectares of land is removed from agriculture sector. Analysis of cotton yield data shows the tendency of decline in a harvest mainly due to the increase in salinity level. Taking into account all above the remedy actions should aim at carrying out the afforestation measures more intensively as a first aid for retention of the salt dust from the bottom of the sea. Moreover, there is a need in applying a crop rotation policy for sustenance of the soil fertility Land degradation Aral Sea (Uzbekistan and Kazakhtan) Crop Effect of salts on Aral Sea (Uzbekistan and Kazakhtan) Agricultural productivity Aral Sea (Uzbekistan and Kazakhtan) Shipin, Oleg V., Examination Committee Schmidt-Vogt, Dietrich, Examination Committee Shrestha, Rajendra Prasad, Chairperson ADB-Japan Scholarship Program (ADB-JSP), Scholarship donor Asian Institute of Technology.
