2. Geographical Approach
The issue of water scarcity in Uzbekistan encompasses a multitude of geographical facets that necessitate thorough exploration through comprehensive scientific articles. However, within the confines of this particular case study, we will narrow our focus to the specific aspect of water scarcity as an environmental problem in a distinct region. The ensuing discussion sheds light on key aspects pertaining to this subject matter. Uzbekistan relies predominantly on two major water sources, namely the Amu Darya and Syr Darya rivers, which have historically been vital for the region's water supply. The presence of the Aral Sea also played a significant role; however, it currently faces a severe crisis. Compounded by the region's economic challenges, the scarcity of water has evolved into an urgent and pressing concern. Uzbekistan possesses a mere 10 cubic kilometers of river water, accounting for a mere 0.23% of the total river water resources in the Commonwealth of Independent States (CIS). Given this limited availability and various contributing factors, the conservation and judicious utilization of water become paramount, particularly in arid regions. It is imperative to understand the underlying causes of the water crisis, which can, in part, be attributed to the initial impact of global warming. In this regard, elucidating the reasons behind the occurrence of drought becomes crucial. Experts hold diverse opinions on the cause of the recent observed drought, with one perspective linking it to the region's susceptibility to global climate change. This global environmental shift not only leads to significant ecological disasters but also exacerbates drought conditions in the area.
Scientists have emphasized several factors contributing to the water scarcity issue in Uzbekistan. These include insufficient rainfall, rising surface temperatures resulting from global warming, and an increase in carbon dioxide and other greenhouse gases in the atmosphere (Lal, 2004). While afforestation and the expansion of green areas are potential solutions, they heavily rely on artificial irrigation, which can lead to soil salinity. Consequently, it becomes imperative to implement effective measures to combat soil salinization, particularly as agricultural land in Uzbekistan experiences escalating levels of salinity. Techniques such as raising the water table and creating nearby wetlands can help alleviate water salinity. The issue of clean drinking water also presents a significant challenge, partly stemming from the mismanagement of groundwater utilization. To address this concern effectively, proper waste management practices must be established. Furthermore, it is crucial to recognize the intertwined nature of political tensions and the water problem. For instance, the Surkhandarya region heavily relies on the Amu Darya River as a vital water source for the Oltinsoy district (see
Figure 1), underscoring the interconnectedness of water issues and regional politics. It is important to note that the geographical context plays a crucial role in comprehending the dynamics of water scarcity in Uzbekistan. While this case study focuses on a specific region, it highlights the broader regional and global factors that contribute to the country's water crisis. Subsequent sections will delve further into the specific challenges faced by the chosen case study district and propose potential solutions to address the prevailing water scarcity.
In addition to the existing information, it is crucial to consider additional factors that contribute to the case study of water scarcity in Uzbekistan. These factors shed further light on the specific geographic context and enhance the understanding of the complexity of the situation.
Firstly, the examination of water management infrastructure in the Oltinsoy case study district is paramount. Assessing the efficiency and capacity of irrigation systems, reservoirs, and canals, as well as identifying any infrastructure deficiencies or outdated practices that exacerbate water scarcity, provides critical insights into the issue.
Secondly, understanding demographic and agricultural patterns in Oltinsoy is essential. Analyzing population growth, agricultural land use, and crop choices (such as cotton and grain) helps identify areas where water resources are heavily utilized and where sustainable practices can be implemented.
Thirdly, conducting a hydrologic analysis of the Amu Darya River, the primary water source for Oltinsoy County, is valuable. This analysis provides insights into the river's flow patterns, seasonal variations, and potential factors affecting its water availability. Additionally, considering the effects of upstream water use and detours on downstream water availability enhances understanding. Socioeconomic factors should not be ignored as well. Examining the socioeconomic status of the local population, their access to water resources, livelihood dependence on agriculture, and potential socioeconomic impacts of water scarcity on the community are crucial aspects to consider.
Furthermore, studying the ecological consequences of water scarcity in Oltinsoy is important. Assessing the impact on local ecosystems, biodiversity, and overall ecological balance, as well as examining the effects on local flora and fauna, and potential conflicts arising from resource competition among stakeholders, provides a comprehensive understanding of the environmental impacts. By considering these additional aspects, the case study of water scarcity in Oltinsoy, Uzbekistan, becomes enriched with a more comprehensive assessment of geographic, hydrologic, socioeconomic, and environmental factors. This approach leads to a clearer and more robust analysis of the water scarcity problem and supports the formulation of effective strategies and solutions to address it.
Following the collapse of the Soviet Union, the water issue in Central Asia has the potential to become a source of conflict among the nations in the region. Although there have been some cases of water-related tensions, they are not the primary focus of this study. Currently, the majority of the water flowing through Uzbekistan comes from areas outside the republic. The Intergovernmental Commission on Water Use, established in 1998, has been working to address this issue in Central Asia. However, unlike international agreements on water use, there is no written agreement in place. If there is a significant shortage of water in the region, conflicts could escalate. Water usage in the area is mainly divided between irrigation and power generation, which creates conflicting interests among the countries involved. The energy system is not beneficial to Kazakhstan and Uzbekistan in this situation, while the irrigation system is not in the interest of Kyrgyzstan and Tajikistan. Consequently, Uzbekistan and Kazakhstan are compelled to rely on electricity, particularly during the summer, depending on the amount of water imported from Kyrgyzstan. The increasing demand for electricity, especially in Tajikistan and Kyrgyzstan, leads to electricity shortages. Both countries are making efforts to generate electricity from water. Kazakhstan and Uzbekistan, being the region's largest water consumers, have concerns regarding the situation.
Currently, water use in the region is regulated by the intergovernmental commission established in 1998 (Qi et al. 2008). However, there is no signed agreement among the states that aligns with international water use agreements. The speculation of severe drought affecting the region may lead to political unrest in Central Asia. Therefore, it is crucial to enact laws that recognize the transboundary nature of the Amu Darya River and ratify the International Convention on Transboundary Rivers. While Uzbekistan has recently acceded to the International Convention on Transboundary Waters, Tajikistan and Kyrgyzstan have not yet joined. Joining the convention could potentially address many water-related issues in the region.
