Abstract:
Uzbekistan faces a severe water crisis driven by climate change,
population growth, outdated infrastructure, and transboundary water
dependencies. This thesis examines the multifaceted water problem in
Uzbekistan, focusing on the depletion of the Amu Darya and Syr Darya rivers,
inefficient irrigation practices, and the socio-economic impacts of water scarcity.
Drawing on recent literature, the analysis highlights the environmental
degradation of the Aral Sea, agricultural inefficiencies, and limited access to
clean drinking water, particularly in rural areas. The study critiques the
effectiveness of current water management policies and proposes subjective
recommendations, including the adoption of water-saving technologies, regional
cooperation, and legislative reforms. By addressing these challenges, Uzbekistan
can mitigate its water shortage, projected to increase fivefold by 2050, and
foster sustainable development. This thesis underscores the urgency of
collective action to ensure water security in an arid, landlocked nation.

Introduction
Uzbekistan, a double-landlocked, arid nation in Central Asia, grapples with
a critical water crisis that threatens its economic stability, environmental
sustainability, and public health. With 90% of its water consumed by agriculture
and 80% sourced from transboundary rivers, Uzbekistan faces economic water
scarcity, defined as less than 3,000 m³ per capita annually (1,870 m³ in
Uzbekistan). The depletion of the Amu Darya and Syr Darya rivers, exacerbated
by climate change, upstream damming, and inefficient Soviet-era irrigation
systems, has reduced water availability, with projections indicating a fivefold
increase in shortages by 2050. The environmental catastrophe of the Aral Sea,
once a vital water div, underscores the consequences of mismanagement,
while rural communities struggle with limited access to clean drinking water,
leading to health issues like hepatitis.

This thesis aims to analyze the causes and impacts of Uzbekistan’s water
problem, critically evaluate current management strategies, and propose
actionable solutions. By synthesizing recent literature, including studies from
the World Bank, International Water Management Institute (IWMI), and regional
analyses, the study addresses the interplay of geopolitical, environmental, and
socio-economic factors. The proposal section offers subjective recommendations
to enhance water security, emphasizing technological innovation and regional
cooperation. As global water shortages intensify, Uzbekistan’s experience
provides critical lessons for arid regions worldwide, highlighting the need for
sustainable water governance.
Analysis
Causes of Water Scarcity
Uzbekistan’s water crisis stems from multiple interconnected factors. First,
climate change reduces water availability through decreased snowfall, glacier
retreat, and increased evaporation due to rising temperatures. The World Bank
projects a 10-15% streamflow decline in the Amu Darya and 2-5% in the Syr
Darya by 2050, reducing Uzbekistan’s water supply. Second, transboundary
dependencies exacerbate scarcity, as 80% of Uzbekistan’s water originates in
upstream Tajikistan and Kyrgyzstan, where hydropower dams like Rogun
reduce downstream flows.
Third, outdated infrastructure from the Soviet era, including dilapidated
irrigation canals, results in 30-60% water losses. The collapse of the Sardoba
dam in 2020 highlighted infrastructure vulnerabilities.
Agricultural practices, particularly cotton cultivation, consume 90.6% of
water, with inefficient flood irrigation exacerbating losses. The Aral Sea crisis,
caused by decades of over-irrigation, has reduced inflow from 55 km³ in 1960 to
near zero in dry years, leading to salinization and desertification. Finally,
population growth (from 30 million to a projected 40 million by 2030) increases
demand, reducing per capita water availability from 3,048 m³ in 2005 to 1,589
m³ in 2020.
Impacts
The water crisis has profound socio-economic and environmental impacts.
Agriculture, Uzbekistan’s economic backbone, faces declining yields, with
300,000 hectares of crops lost to drought in Karakalpakstan in 2000. Public
health suffers, as 71% of rural households rely on unsafe water sources, leading
to waterborne diseases. Environmental degradation, particularly the Aral Sea’s
shrinkage, has caused salt storms, affecting 17-20 tons of salt per hectare

annually. Geopolitical tensions arise from upstream-downstream conflicts, with
Uzbekistan’s diplomacy easing but not resolving disputes.
Current Management
Uzbekistan has initiated reforms under President Mirziyoyev, including the
National Agricultural Development Strategy (2020-2030), which prioritizes
water-saving technologies. Since 2018, drip irrigation has expanded to 1 million
hectares (27% of irrigated land), reducing water use by 40-50%. Subsidies (USD
133 million from 2019-2022) and tax exemptions incentivize adoption. The EU-
funded “Water Governance in Uzbekistan” project introduced smartsticks,
electronic devices improving water accounting for 500 farmers. However, these
measures are insufficient against projected shortages, and regional agreements
on transboundary water remain underdeveloped.
Discussion
Uzbekistan’s water crisis reflects a complex interplay of natural, historical,
and policy-related factors. The reliance on transboundary rivers places
Uzbekistan at the mercy of upstream nations, a challenge compounded by the
lack of enforceable regional agreements. Soviet-era infrastructure, designed for
large-scale cooperatives, is ill-suited for smaller farms post-independence,
leading to inefficiencies. The Aral Sea’s collapse serves as a stark warning of
unsustainable practices, yet cotton remains a water-intensive priority, reflecting
economic dependencies over environmental concerns.
Recent reforms, such as smartsticks and drip irrigation, are promising but
limited in scale. The government’s focus on technological solutions overlooks
deeper issues like low water tariffs (USD 0.02-0.035/m³), which discourage
conservation, and the absence of a comprehensive water law. Critically, while
sources like the World Bank emphasize infrastructure upgrades, they may
underplay the socio-political barriers to regional cooperation, such as upstream
nations’ hydropower priorities. Uzbekistan’s diplomacy has reduced tensions,
but without binding international standards, conflicts persist.
Comparatively, countries like Israel, with advanced drip irrigation covering
90% of farmland, offer models for efficiency. Uzbekistan’s arid climate and land
availability provide opportunities for scaling such technologies, but financial
constraints and low public awareness hinder progress. The crisis demands a
holistic approach, balancing technological, legal, and diplomatic strategies to
ensure long-term water security.
Proposal with Subjective Opinions

Based on the analysis, I propose the following subjective recommendations
to address Uzbekistan’s water crisis, blending practical solutions with optimism
for regional collaboration:
Scale Water-Saving Technologies:
Uzbekistan should aim to expand drip
irrigation to 75% of irrigated land by 2035, following Israel’s model. Subsidies
should be increased, and local production of irrigation equipment (currently 50
enterprises) scaled to reduce costs. In my view, prioritizing drip irrigation over
flood methods is critical to halving agricultural water use, preserving resources
for future generations.
Enact a Comprehensive Water Law:
A national water law should mandate
conservation, set higher tariffs for excessive use, and establish a regulatory div
for monitoring. This would address the current fragmented policy landscape,
which I believe undermines accountability. Tax exemptions for water-saving
technologies should extend beyond five years to encourage adoption.
Strengthen Regional Cooperation:
Uzbekistan should lead negotiations for
a Central Asian water treaty, modeled on the EU’s Water Framework Directive,
ensuring equitable transboundary water sharing. While upstream nations
prioritize hydropower, I argue that joint investments in renewable energy (e.g.,
Uzbekistan’s solar potential) could reduce dam reliance, benefiting all parties.
Public Awareness Campaigns:
Educational programs should promote
water conservation, targeting farmers and rural communities. I believe
empowering <1>empowering local Water Consumer Associations (WCAs) with
training on smartsticks and modern irrigation could transform grassroots water
management.
These proposals, though ambitious, are feasible with international support
(e.g., World Bank, ADB loans). Uzbekistan’s progress since 2018 inspires
confidence, but bolder action is needed to avert a crisis that could destabilize the
region.
Conclusion
Uzbekistan’s water crisis, driven by climate change, transboundary
dependencies, and inefficient practices, poses an existential threat to its
economy, environment, and public health. The depletion of the Amu Darya and
Syr Darya, coupled with the Aral Sea’s collapse, underscores decades of
mismanagement. While reforms like drip irrigation and smartsticks show
promise, their scale and impact remain limited against a projected 25% water
shortfall by 2030. This thesis proposes scaling water-saving technologies,
enacting a national water law, fostering regional cooperation, and raising public

awareness to mitigate the crisis. By learning from global best practices and
leveraging its solar potential, Uzbekistan can chart a sustainable path, ensuring
water security for its growing population and setting a model for arid nations
worldwide.
