Abstract

The main goal in water efficiency in agriculture is to obtain more products with the same amount of water. In this respect, the use of irrigation performance indicators is important for increasing agricultural water efficiency. This study was conducted to evaluate agricultural water efficiency in the Konya closed basin, which is the region most affected by drought in Turkey. For this purpose, performance indicators selected for evaluating agricultural water efficiency were determined in irrigation associations taken as material for the years 2016–2020.

In the research area, the following water use efficiency indicators were determined: annual amount of irrigation water distributed 1.750–517.462 million m³ yr⁻¹ (MCM yr⁻¹), annual amount of irrigation water distributed per unit area 0.529–8.688 MCM ha⁻¹, annual amount of irrigation water distributed per unit irrigated area 0.787–33.909 MCM ha⁻¹ and annual water supply ratio ranging between 0.220 and 52.600. The following agricultural water efficiency performance indicators were determined: income obtained for unit irrigation area, 127–5075 US$ ha⁻¹; income obtained per unit irrigated area, 656–12353 US$ ha⁻¹; income obtained per unit irrigation water taken into the network, 0.104–6.771 US$ m⁻³; and income obtained per unit irrigation water consumed, 0.236–37.358 US$ m⁻³. Correlation analysis was carried out to identify the significance of the relationships between the performance indicators, and the results were discussed.

农业用水效率评估：科尼亚封闭盆地案例

农业用水效率的主要目标是用相同的水量获得更多的产品。因此，使用灌溉性能指标对提高农业用水效率非常重要。本研究旨在评估土耳其受干旱影响最严重的科尼亚封闭盆地的农业用水效率。为此，在以 2016-2020 年为材料的灌溉协会中确定了选定用于评价农业用水效率的绩效指标。在研究区域内，确定了以下用水效率指标：年灌溉配水量 1.在研究区域内，确定了以下用水效率指标：年灌溉配水量 1.750-5.17462 亿立方米-¹（MCM yr-¹），单位面积年灌溉配水量 0.529-8.688 MCM ha-¹，单位灌溉面积年灌溉配水量 0.787-33.909 MCM ha-¹，年供水率在 0.220-52.600 之间。确定了以下农业用水效率绩效指标：单位灌溉面积收益，127-5075 美元 ha-¹；单位灌溉面积收益，656-12353 美元 ha-¹；单位入网灌溉水量收益，0.104-6.771 美元 m-3；单位灌溉耗水量收益，0.236-37.358 美元 m-3。为确定绩效指标之间关系的重要性，进行了相关性分析，并对结果进行了讨论。

期刊介绍： Human intervention in the control of water for sustainable agricultural development involves the application of technology and management approaches to: (i) provide the appropriate quantities of water when it is needed by the crops, (ii) prevent salinisation and water-logging of the root zone, (iii) protect land from flooding, and (iv) maximise the beneficial use of water by appropriate allocation, conservation and reuse. All this has to be achieved within a framework of economic, social and environmental constraints. The Journal, therefore, covers a wide range of subjects, advancement in which, through high quality papers in the Journal, will make a significant contribution to the enormous task of satisfying the needs of the world’s ever-increasing population. The Journal also publishes book reviews.
