Food Security and Effective Water Resources Management under Climate Change

本研究的主要目的是评价该流域主要作物的有效水资源利用策略。这些措施考虑到粮食安全，以最大限度地利用现有水资源来种植河流流域的主要三种作物。利用我们的框架，估计并提出了作物的需水量，包括对几种作物的水分可用性因子的评估。该流域的水盐度图是根据在灌溉旺季进行的实地观测和市政当局提供的数据绘制的。正如预期的那样，下游地区非常容易发生水矿化，需要大量的水。发现水的盐度有助于确定该地区的作物产量。该地图是作物生产力的重要指标，用于预测作物需水量。利用今年的结果，我们能够改进我们的分析，并表明在不久的将来，减少水流的影响将相当明显。该研究成果在乌兹别克斯坦农业部、科学院组织的世界水资源大会和“边际水资源利用创新促进抗旱性农业和粮食安全”国际研讨会上进行了介绍。在塔什干举行的讨论会得到了主要电视频道和报纸的广泛报道，讨论了提高用水效率的主要问题之一。组织了与科学委员会一起进行的研究旅行，以介绍乌兹别克斯坦的环境问题，并访问乌兹别克斯坦的前咸海海床地区。

Main goal of this study is to evaluate efficient water use strategy for the main crops in the river basin. The measures consider food security to maximize use of the available water resources for the main three crops grown in the river basin. Using our framework, water requirement for the crops including assessments of the water availability factors to several crops were estimated and presented. Water salinity map of the basin were prepared based on field observations, made in high irrigation season and municipalities provided data. As it was expected, downstream area are significantly prone to the water mineralization and requires significant amounts of water to be applied. Finding water salinity helps to define crops productivity in that areas. The map is important measure for crops productivity used to predict water to crop requirement.Using this year's outcomes we were able to improve our analysis and show that the impact of the reduced water flow will be quite noticeable in the near future. Results of this research were presented in the World Water Congress, and International seminar on “Innovations in Marginal Water Resource Use for Resilient Agriculture and Food Security” organized by the Ministry of Agriculture, Academy of Science of the Uzbekistan. The seminar in Tashkent, was broadly covered by the main TV channels and newspapers and addressed one of main issues on improving water usage efficiency.Research tour with the JSCE to introduce environmental issues in Uzbekistan and visit former Aral Sea bed area in Uzbekistan were organized.
