Precipitation and elevation shape land and water usage in Central Asia, distinguishing the southern irrigated oases from the steppes, deserts, and prairies, where instead nomadic pastoralism (sometimes rain-fed agriculture) is economically rational. The former was included in Russian Turkestan, the latter in the Steppe provinces. The colonial state recognized land usage rights of the nomads; while not formally admitting land property among the settled population, it allowed them to enjoy it within Islamic law. Nomads paid a capitation; at first tilled land continued to be taxed as a share of the real harvest. Land-assessment works from the 1890s, though, imposed a tax based on the estimated harvest value, initially on irrigated land and then, with some differences, on rain-fed land. Irrigation was paid for eminently through corvées. The increase in the share of land under cotton did not derive from state coercion but from factor endowments and absolute and relative prices. Subsidies, in the form of import duties and, above all, a growing tax break contributed to this. Despite political claims, new irrigation had a limited impact under the tsars. While the “cotton boom” altered the landscape and local economy of the oases, in the Steppe and Semirechie (now south-eastern Kazakhstan and Kyrgyzstan) the natives lost land to settler peasants from European Russia. The latter received land that statisticians and surveyors had deemed excess for the nomads and former nomads. Conflicts around land, water, and forests coalesced in the 1916 uprising, which in turn initiated a cycle of violent retaliation between Russians and natives that would last until the early 1920s. With the establishment of Soviet power, a first land reform “decolonized” former resettlement areas; in 1925 and 1927 another land reform aimed at reducing landlessness in southern Central Asia, while restoring pre-war output levels and cotton procurement mechanisms.
