Soil salinity and low drainage capacity are major factors limiting crop yield and low agricultural water productivity (WP) in the Lower Karkheh River Basin (L-KRB) in the southwest to south of Iran. The objective of this chapter is to provide and elaborate cost-effective and adaptive solutions and measures for the amelioration of the situation and for enhancing WP in this area. The suggested approaches and measures are based on field experiments conducted both under farmer,Äôs field and research station. The main cultivated crop in the region is wheat. For the first step, WPs of wheat were determined under some farmer,Äôs fields. Based on results, WP of wheat in the area varied between 0.24 and 0.77 kg/m3. The study aimed to provide simple measures and management practices for reducing salinity and waterlogging hazards and ultimately improving crop WP in the studied area. The focus of experiments was on the methods of land preparation for irrigation, sowing methods by the different adapted machines, and seeding rates. Changing of traditional basin irrigation to a modern mixed system of border-basin irrigation method could improve irrigation performance and will reduce applied water greatly and hence could improve WP. Construction and provision of fixed and low-cost water intake structures on farm ditches could have more impacts on the improvement of irrigation performance as well. Optimum (modern) border irrigation and optimum basin treatments had higher WPs (1.36 and 1.04 kg/m3, respectively) than the traditional irrigation practiced by the farmers (0.61 kg/m3). Although the WP of optimum border was highest, the basin irrigation method is suggested because this method is more adaptive and sustainable in terms of acceptance by the local farmers.

The Karkheh River Basin is the third largest basin in Iran after Karoon and Dez, and occupies a strategic position on the western boundary of the country. The basin has seen remarkable ancient feats of engineering, and has a long history of wheat and barley production, complemented by horticulture. With the growth of the modern nation-state of Iran, water development has progressed steadily in tandem with rising populations and urbanization. The report aims to understand the historical setting and present situation of water development and allocation, in relation to rural development and agrarian policy. It provides the contextual backdrop for further research on the management of water to improve livelihoods in the basin through integrated and sustainable management of land and water resources. It provides further information on the changes in surface flows out of the component subbasins and looks at the development, use and consequences of groundwater abstraction.

WATER, CLIMATE CHANGE, AND SUSTAINABILITY An in-depth review of sustainable concepts in water resources management under climate change Climate change continues to intensify existing pressures in water resources management, such as rapid population growth, land use changes, pollution, damming of rivers, and many others. Securing a reliable water supply—critical for achieving Sustainable Development Goals (SDGs)—requires understanding of the relation between finite water resources, climate variability/change, and various elements of sustainability. Water, Climate Change, and Sustainability is a timely and in-depth examination of the concept of sustainability as it relates to water resources management in the context of climate change risks. Featuring contributions by global authors, this edited volume is organized into three sections: Sustainability Concepts; Sustainability Approaches, Tools, and Techniques; and Sustainability in Practice. Detailed chapters describe the linkage between water and sustainable development, highlight the development and use of new measuring and reporting methods, and discuss the implementation of sustainability concepts in various water use sectors. Topics include localizing and mainstreaming global water sustainability initiatives, resilient water infrastructure for poverty reduction, urban water security for sustainable cities, climate actions and challenges for sustainable ecosystem services, and more. This important resource: Reviews contemporary scientific research and practical applications in the areas of water, climate change and sustainability in different regions of the world Discusses future directions of research and practices in relation to expected patterns of climate changes Covers a wide range of concepts, theories, and perspectives of sustainable development of water resources Features case studies of field and modelling techniques for analyzing water resources and evaluating vulnerability, security, and associated risks Discusses practical applications of water resources in contexts such as food security, global health, clean energy, and climate action Water, Climate Change, and Sustainability is an invaluable resource for policy makers water managers, researchers, and other professionals in the field, and an ideal text for graduate students in hydrogeology, climate change, geophysics, geochemistry, geography, water resources, and environmental science.

Iran is facing a serious water scarcity and the Government of Iran is trying to implement technical and institutional measures to meet the challenge. One of the key strategies being persuaded by the Iranian authorities is the devolution of management responsibility to users. Thus, irrigation management transfer (IMT) has been adopted as a key strategy to improve the operation and maintenance, and thereby reduce losses, and enhance the sustainability of irrigation infrastructure. However, IMT efforts are at an inception stage and are largely happening in areas where infrastructure is under rehabilitation. The key objective of this paper, thus, was to review the ongoing IMT efforts in the two provinces of Iran, as well as the lessons from the neighboring countries, and propose a viable framework for implementing IMT. To get the first hand information of the IMT activities in Iran, field visits were carried out in the provinces of Qazvin and Kermanshah where two big pilot projects are being carried out. For comparative analysis of the IMT situation in neighboring countries, a comprehensive review of experiences in Sri Lanka, India, Pakistan, Turkey and Central Asia was carried out through literature survey. Based on the synthesis of lessons from this exercise, the paper proposes a framework for irrigation management transfer in Iran.
