Community of Practice

Over the past few decades, there have been significant global advances to ensure more equitable gender representation for inclusive decision-making, especially in the education and healthcare sectors. However, in issues related to the Water-Energy-Food Ecosystem Nexus, women’s role remains an underappreciated ‘asset’ in most parts of the world.

There are about 280 reservoirs in Central Asia (CA) designed to regulate the seasonal and annual river flow. Most of them are multifunctional and are used for agricultural needs, water supply, hydropower generation, and flood protection.

Water reservoirs in the region are subject to intense negative processes of pollution and silting, as well as clogging caused by mountainous terrain.

In November 2021 Glasgow, United Kingdom, hosted the 26th UN Climate Change Conference of the Parties (COP26). More than 200 countries participated in the Conference and accepted the Glasgow Climate Pact. This global agreement will accelerate action on climate during the upcoming decade. One of the topics raised during the conference was WEFE Nexus approach and possible contribution of its application while implementing the Glasgow Climate Pact.

The geographical and climatic features of the Central Asian region, and the uneven distribution and consumption of its natural resources determine the dependence of the economic potential of each state, in particular, on the efficient use of water and energy resources. However, Central Asia has an ideal set of complementary regional energy sources and generation structures that will help realize the benefits of regional energy cooperation. Strengthening the integration of the region's economies through increased energy trade between the countries of Central Asia and neighboring regions can help the region restore and maintain economic growth and regional cooperation.

Hydropower provides up to 98% of electricity in some of Central Asian countries such as Kyrgyz Republic, and Tajikistan. Hydropower plants depend on the water content of the rivers fed by glacial melt water and snowmelt. However, as the climate warms, most climate models predict significant changes in the dynamics of the precipitation patterns as well as changes in glacial runoff. 

The Talimarjan reservoir is one of the largest artificial reservoirs in Uzbekistan and plays a key role in the water supply of the Kashkadarya region. The Kashkadarya region historically had the potential to develop agriculture but was considered water scarce, and in Soviet times it was decided to build a reservoir and a cascade of pumping stations that would direct water from the Amu Darya to irrigate the developed lands where cotton, wheat and other important crops are grown, and as well as supplying the population with drinking water.

Climatic changes in Central Asia are causing the reduction of the Tien-Shan Mountain glaciation. Meanwhile, it is the mountain glaciation that is the key factor in the stable water supply to the hydrological system of this arid region. Meltwater from glaciers and seasonal snow cover largely feed Central Asian rivers. The countries use this water for economic activities such as irrigated agriculture and hydropower generation. However, the accelerated melting of glaciers poses additional risks to sustainable development and regional water, energy, and food security in the region. 

In recent years, the Water-Energy-Food Nexus approach has attracted growing attention within international politics, academia, and other areas of society. The tragedy of the Aral Sea in Central Asia demonstrates how wrong planning, lack of understanding of the interconnection of various sectors can lead to tragic consequences. The Central Asian countries are currently striving to reduce the detrimental impact of the Aral Sea crisis on the environment, on various sectors of economic development, ecosystems, and the health of the population of the Aral Sea region. In this regard, great efforts are directed by countries to the practical solution of these problems, considering the relationship of "water-energy-food-ecosystems" - the introduction of the Nexus campaign.

Achieving sustainable development in river basins, including in Central Asia, requires effective coordination in decision-making and planning over the use of natural resources - water, energy and land.

International water law offers an overarching framework for addressing a broad range of water-related challenges that span across scales (international vs regional), sectors (energy, agriculture, environment) and disciplines (political, economic, societal and environmental).

Water is key for the socio-economic development of all the countries sharing the Aral Sea Basin (ASB). In fact, it is the availability of water that determines the region’s economic performance, social coherence, and even political stability. The environmental aftermath of water mismanagement in the region led to the creation of a 5-million-hectare desert—the Aral-Kum. The collapse of the Soviet economic system immediately resulted in the disintegration of the compensatory system and mechanisms in the region involving water and energy and pushed countries towards more self-sufficiency and independence in all economic areas, including water, energy, and agriculture.
