Impact Of Regional Climate Changes On Changes In River Water Content In Uzbekistan, A.T. Salokhiddinov, P.A. Khakimova, R.V. Toryanniova, O.A. Ashirova, A.G. Gofurov

Irrigation and Melioration

The paper presents the research results on the analysis of the climate change impacts on the potential of water resources in Central Asia. We analyzed the materials of an extensive database of monitoring data from numerous gauge stations on different river basins and satellite data information. A quantitative assessment of the transformation of river hydrographs, the growth of flow variability in the Republic of Uzbekistan's major rivers, in connection with climate change, was performed. The specific features of the impact of climate changes on changes in the water content of rivers in Uzbekistan in large and small river basins are …

Assessment Of The Impact Of Climate Change On Hydrological Processes In The Chirchik River Basin, Kh.Sh. Gafforov, Sh.D. Sh.D.Tursunboev

Irrigation and Melioration

The importance of assessing past and future climate differences plays an important role in future planning in relation to climate change. This situation requires urgent and concerted action in several areas: technology, infrastructure, politics, economics, and the environment. The article evaluates the impact of changes in precipitation intensity on the water level in the global circulation model (GCM) RCP 4.5 and 8.5 scenarios in the 2030s, 2050s, and 2070s. This study is a useful reference for improving water resource management and ensuring the sustainability of agricultural products in the future, as well as for improving operational water management and agricultural …

Empirical Assessment Of Climate Change Impacts On Agriculture In Samarkand Region, Sh.B. Babakholov

Irrigation and Melioration

Agricultural production is highly sensitive to climate factors like other endogenous factors, and the expected climate change projections may have a negative impact on the efficiency and income of agricultural producers. Therefore, this study aims to analyze the impact of changes in climatic factors (average air temperature and precipitation) on the technical efficiency of cotton growing farmers as its determinants in Samarkand region. Empirical analyzes were performed on the cases of 1141 cotton-growing farms using panel-based Time-Invariant Inefficiency model. According to the results of the analysis, cotton farms in the region have an average technical efficiency of 76%, which in …

Economic Assesment Of The Impact Of Climate Factors On Wheat Yield In Samarkand Region, Sh.B. Babakholov

Irrigation and Melioration

Agricultural production is highly vulnerable to climate shocks and predicted climate consequences may pose severe challenges to the resilience of Uzbek agricultural system, especially in terms of food security and income stability of rural producers. In this context, present study proposed to assess the impact of climate factors, such particular changes in mean temperature and rainfalls on total output of wheat-cultivating farmers in Samarkand region. By considering irrigation source and heterogeneous geography of the region, farmers engaged in wheat production were analyzed in two: upstream and downstream zones using Fixed effect panel approach. The empirical findings of study revealed that, …

Determination And Assessment Of The Spatio-Temporal Changing Dynamics In The Groundwater Level And Mineralization In Irrigated Areas Under Climate Change (As An Example Of Syrdarya Province), S. Khasanov, S. Adilov, R. Kulmatov

Irrigation and Melioration

In the irrigated lands of the Aral Sea Basin, salinization processes are taking place as a result of rising groundwater levels and increasing its mineralization due to the unsustainable use of water and land resources. This, in turn, leads to the withdrawing of arable land and a decrease in crop yields. This is especially the case in the irrigated areas of the lower reaches of the Amudarya and Syrdarya rivers, located in Uzbekistan, southern Kazakhstan, and Turkmenistan. This research was aimed to learn and evaluate the long-term changing behavior of groundwater level and mineralization in the irrigated areas of the …

Methods For Incorporating Ecological Impacts With Climate Uncertainty To Support Robust Flood Management Decision-Making, Caitlin M. Spence

Doctoral Dissertations

Modern and historic flood risk management involves accommodating multiple sources of sources of uncertainty and potential impacts across a broad range of interrelated sectors. Sources of uncertainty that affect planning include internal climate variability, anthropogenic changes such as land use and system performance expectations, and more recently changes in climatology that affect the resources supporting the system. Flood management systems potentially impact human settlements within and beyond the systems’ scope of planning, local weather patterns, and associated ecological systems. Federal guidelines across nations have called for greater consideration of uncertainty and impacts of water resources planning projects, but methods for …
