It focuses on low and high flows, long-term mean flow and flow duration curves. Since it lists the actual formulae, it can be used as a quick reference guide for selecting a suitable technique for various geographical regional and/or river basins in India.

Despite historical precedents and efforts in the twentieth and early twenty-first centuries, the potential for the integration of fish production (capture fisheries and aquaculture) and irrigation systems has yet to be fully realized. Capturing these underutilized opportunities for the integration of fisheries and aquaculture could significantly increase local economies, food security, household incomes and livelihood diversity within irrigated agriculture systems. To re-examine the potential of fisheries in irrigation systems, the concept of the extended command area (ECA) is used, expanding the conventional definition of an agriculture irrigation command area. The reason for this expanded definition is because all elements of an irrigation system, from upstream dam storage to downstream drainage areas, offer opportunities for increasing fish production. Many of these opportunities may be realized at no additional cost to the main irrigated crop. This document provides an introduction to the ways fisheries and aquaculture already co-exist with irrigation and explores the threats and opportunities that arise from this. A key concept for sustaining and enhancing inland capture fisheries is “connectivity”– a fundamental basis for ensuring adequate environmental conditions to allow fish to flourish within an aquatic ecosystem such as a river, lake, or wetland. Improving connectivity within an ECA can restore elements of ecological services that may have been compromised or degraded through irrigation, water management or through other rural infrastructure development such as road construction. Practical application of the integration of fisheries and irrigation systems is explored through the use of the Ecosystem Approach to Fisheries (EAF) in the context of irrigation systems. The proposed process links the development of an EAF management plan for fisheries to irrigation system operation and is given the acronym EAFm-i. A key part of this linkage is an assessment of water resources in the system and the management of water for delivery to fisheries. Additional tools to support the EAFm-i process are also described. Although the experience and approach are drawn largely from irrigation systems and inland capture fisheries in Southeast Asia, the application of the ECA concept and approach will be relevant to any irrigation or water management system where there is potential for the closer integration and harmonization of fisheries and irrigation systems and where water users are interested in realizing this potential. This short paper is intended to encourage fisheries and irrigation specialists to engage in greater dialogue and cooperation over the integration of fisheries into irrigation planning and to support piloting of an EAFm-i process, which can be the basis for further development.

DOWNLOAD EBOOK →Aquaculture for both finfish and shellfish is expanding rapidly throughout the world. It is regarded as having the potential to provide a valuable source of protein in less developed countries and to be integrated into the farming systems and livelihoods of the rural poor. This book addresses key issues in aquaculture and rural development, with case studies drawn from several countries in South and South-East Asia. Papers included cover topics ranging from production and technical issues (such as pond culture and rice field fisheries) to social aspects and research and development methodology. The book has been developed from a meeting of the Asian Fisheries Society. It is aimed at all concerned with aquaculture and rural development.

Trends in resource use and environmental impact are very evident in inland waters which are particularly vulnerable as they act as collectors of all the activities occurring in their basins and rank as some of the most endangered ecosystems in the world. The principle changes influencing the evolution of the aquatic resource for fisheries are described in this book, which has been compiled for the Food and Agriculture Organization of the United Nations.

The consultation was held at Almaty, Kazakhstan, from 25 to 29 September 2001. The document brings together twelve papers that review the present use of irrigation systems for fisheries in the countries of the arid belt of Asia, from Turkey to China. The individual papers deal with the following countries and areas: Xinjiang Uygur Autonomous Region (China), India, the Islamic Republic of Iran, Kazakhstan, Kyrgyzstan, Mongolia, Pakistan, Turkey and Uzbekistan. While some countries in the arid belt are well advanced in the field of fish production from waterbodies of irrigation systems, others are experiencing major difficulties arising from recent changes in their political and economic systems, particularly Mongolia and the countries of Central Asia. Such countries require major assistance. The document includes a summary of recommendations and proposals for further action, as formulated by the expert consultation.
