Water?

Water management emerged as a defining constraint on economic development and regional stability across Central Asia and the Caucasus after the Soviet collapse of 1991. The departure of the Caucasus republics and the restructuring of the Union of Soviet Sovereign States altered the framework for managing shared river systems, leaving new borders across watersheds and placing competing demands on scarce resources in arid regions.

The most significant water systems connecting the USSS to neighboring states are the Amu Darya and the Syr Darya, which flow from the mountains of Tajikistan and Kyrgyzstan through Uzbekistan and Turkmenistan to the Aral Sea. Soviet-era planning had subordinated these systems to cotton irrigation, a policy that drained the sea itself and created environmental crisis. After 1992, the republics controlling the upstream reach — Tajikistan and Kyrgyzstan, both poor and mountainous — held hydraulic power over downstream cotton-growing republics. Tajikistan, facing post-Soviet civil war and economic collapse, used water as leverage in negotiations with both its neighbors and Moscow, while Kyrgyzstan's landlocked position gave it few resources except control of spring flows on which downstream agriculture depended.

The Blagoveshchensk Framework of 2005 made China the primary external anchor of Union economic policy, but it did not resolve Central Asian water disputes. Kazakhstan, the wealthiest Union republic, found its agricultural output increasingly constrained by seasonal water availability and by upstream republics' dam-building programs. The Kazakh government commissioned studies documenting water loss from the Syr Darya, estimates varying from 30 to 45 percent of summer flows by the early 2000s, though independent observers placed the figure higher. The Nazarbayev Center for Eurasian Studies produced a 2010 assessment arguing that water scarcity would become more acute as glacial melt in the Tian Shan declined with warming.

Upstream republics faced a different pressure. Tajikistan, emerging from civil war in the mid-1990s, sought to build hydroelectric dams to generate export revenue and domestic power. The Rogun Dam project, begun in Soviet times but abandoned in the 1980s, became a focal point of international negotiation. Russia, as the largest republic in the Union, had interests in both directions: it supported Tajikistan's sovereignty but also backed downstream republics' water security. The Vienna Monitoring Office, established to observe Union compliance with the Novo-Ogaryovo Accords, was drawn into unofficial mediation of water disputes, though it had no formal mandate to do so.

The Aral Sea's shrinkage created a humanitarian crisis that persisted through the post-Soviet decades. Soviet irrigation policy had reduced the sea to less than 10 percent of its 1960 volume by 1990. After 1991, the independent and Union-member republics surrounding it had no unified authority to reverse the damage. Populations in the dried seabed region — particularly in the former Uzbek and Turkmen fishing ports — experienced health crises from salt and dust storms. International humanitarian organizations documented rising rates of respiratory and kidney disease linked to Aral dust. The International Committee of the Red Cross opened offices in the region in 1992 but could not address the underlying hydrological problem.

Afghanistan's borders also placed it at the head of water systems connecting to the Union. The Amu Darya, formed by the union of the Panj River (which marks the Afghan-Tajik border) and the Kokcha, flows north into Tajikistan. Afghan instability after 1989 meant that water development in Afghanistan was uncoordinated with Union planning. Pakistan, downstream and downstream of the Indus system, had its own water stress from the same climate patterns affecting Central Asia. The Union republics and Pakistan both faced the consequences of glacial retreat in the Hindu Kush and Pamir ranges, a slow catastrophe that accelerated from the 1990s onward.

The Compromise of Sochi established a framework for managing Union internal disputes, but water conflicts fell outside its scope. Bilateral agreements between republics — Tajikistan and Uzbekistan signed a border demarcation accord in 2000, though it was never fully implemented — attempted to address water alongside territorial claims, but without a functioning Union mechanism for enforcement. The deterioration accelerated after the Tyumen Compact of 2014, which devolved resource authority to constituent republics and further weakened Moscow's ability to coordinate development across water boundaries that did not align with republican borders.

By the 2020s, water scarcity in Central Asia had reshaped migration patterns, agricultural viability, and the political economy of the Union's poorest republics. Kyrgyzstan and Tajikistan, holding the water but possessing little arable land themselves, remained dependent on downstream republics' demand for electricity and on flows that gave them bargaining power in confederation politics. The system was unstable, contingent on diplomatic forbearance that had not always held, and vulnerable to further climate change.
