Oasis farming in Central Asia developed primarily due to the presence of mountain ranges that act as "islands of greenery" within the otherwise arid landscape.1

These mountain ranges receive higher levels of precipitation than the surrounding lowlands, leading to the accumulation of snow caps at higher elevations. As this snow melts, it creates streams that descend into the dry desert lands below. These water sources allow for the development of irrigation systems, which are essential for sustaining agriculture in these otherwise parched environments.2134

Additionally, large accumulations of groundwater exist in artesian basins and beneath plains at the foot of mountains, further supporting the extensive oases found throughout the region. By providing a perennial supply of fresh water, these natural features enable the cultivation of crops in areas that would otherwise be unable to support intensive agriculture.564
