The Nonarable Aral: Loss of Productivity in Uzbek Agriculture

Abstract

Agriculture accounts for most of the land use in Uzbekistan, and is consequently the main determinant of environmental quality. As a result, due to the excessive use of production inputs and irrigation, land is widely degraded in Uzbekistan. This chapter explores characteristics and changes in land use, agricultural production, soil ecosystems, and water availability, and their effects on both soil degradation and limits on sustainable development in different agro-ecological zones of Uzbekistan. Secondary data from various sources was collected and processed, and descriptive statistical methods were used to analyze trends, causes, and effects of land degradation. Zones with lower land quality have higher water-use indicators. There is a positive correlation between the land grade and fertilizer application coefficients. Agriculture from the east zone showed sustainable water consumption, the highest average land-quality grade, and has the highest fertilizer-use coefficient. The downstream west zone has the highest water-use and the lowest fertilizer-use indicators. The analysis revealed a great potential for water saving in the west and southeast agricultural zones of Uzbekistan.
