Abstract: This study investigates long-term human activity and environmental degradation dynamics in Central Asia's Fergana Valley. On the basis of archival records, paleoecological data sets, and GIS-based spatial analysis, the project traces how centuries-long activities prompted by trade-expansion led to desertification processes. Integrating historical geography and ongoing ecological modeling, the project illustrates long-term legacies of Silk Road-era activities on land degradation in the present. Mobile pastoral communities, to meet expanding demand for wool, meat, and transport, raised animal populations above sustainable levels. Deforestation too expanded to meet construction timber, fuel, and commerce requirements, stripping hillsides of their covering vegetation. These two forces worked together to create a feedback loop: ground compaction due to overgrazing inhibited water penetration, and deforestation altered rainfall patterns through unbalanced evapotranspiration cycles. Vegetation stripping due to wind and water erosion uncovered topsoil, leading to desertification that still exists. Sandstorms were documented to be on the rise by the 18th century, with arable land losses documented. The study also indicates how the ancient irrigation systems, which were crucial to the agrarian-based economy of the area, became increasingly inefficient as desertification advanced, leading to more severe water shortages. Rotational grazing, native vegetation restoration, and groundwater recharge programs are proposed to reverse the trend of degradation. Lastly, the Fergana Valley experience is an illustration of unfeasible use of resources as well as an example of the application of historical ecology in contemporary conservation practice.
