Download or read book Farming Systems Research into the 21st Century: The New Dynamic written by Ika Darnhofer and published by Springer Science & Business Media. This book was released on 2012-05-30 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Farming Systems Research has three core characteristics: it builds on systems thinking, it depends on the close collaboration between social and biophysical sciences, and it relies on participation to build co-learning processes. Farming Systems Research posits that to contribute towards sustainable rural development, both interdisciplinary collaborations and local actor engagement are needed. Together, they allow for changes in understanding and changes in practices. This book gives an overview of the insights generated in 20 years of Farming Systems Research. It retraces the emergence and development of Farming Systems Research in Europe, summarises the state-of-the-art for key areas, and provides an outlook on new explorations, especially those tackling the dynamic nature of farming systems and their interaction with the natural environment and the context of action.

Download or read book Irrigation Scheme Operation and Maintenance written by W. Bart Snellen and published by Food & Agriculture Org.. This book was released on 1996 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigation Scheme Operation and Maintenance is the tenth in the series of training manuals on irrigation prepared jointly with ILRI (International Institute for Land Reclamation and Improvement). The manual presents some of the difficulties that irrigation organizations confront in undertaking their duties and provides some orientations on how to resolve them. The paper then proceeds to discuss the methods of operating an irrigation network and the working principles involved. The maintenance tasks are discussed. To draw similarities and differences the maintenance of a motorcycle is used as a reference for the corresponding activities in an irrigation scheme. Finally, a reference is made to the need for having an effective financial control whereby the management of the system has enough resources to undertake the operation and maintenance tasks. The manual is addressed to small and medium schemes and assumes that the management organization is already in place.

Download or read book Fundamentals of Smallholder Irrigation written by B. Albinson and published by IWMI. This book was released on 2002 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smallholder irrigation systems–where farm sizes generally range from a fraction of a hectare to 10 hectares–pose special management problems, especially where the water available for irrigation is frequently less than the demand. The intensity of system adjustments required to meet individual farmer demands, and the administrative complexity of measuring and accounting water deliveries have generally proven excessive when attempting to meet “on demand†schedules, resulting in chaos (often characterized by illegal tampering with infrastructure, and vast differences of water use intensity at different locations in the system). The alternative–provision of a simple service, based on proportional sharing of available supplies on the basis of landholdings–has been resilient for many years over vast areas. The approach is based on a clear delineation between the part of the irrigation system that is actively managed (at various flow rates and water levels) and the part of the system that operates either at full supply level (with proportional division of water down to the level at which farmers rotate among their individual farms), or is completely shut. This operational design is known as a “structured†system, and has well-defined hydraulic characteristics, simplifying operation and management, in turn allowing a clearer definition of water entitlements and the responsibilities of agency staff and farmers. The approach is particularly suited to areas where water is scarce and discipline is needed to ration water among users. An additional benefit, which has been demonstrated in modeling studies using a well–proven model relating to water and yield, is that the productivity of water (which is more important than the more traditional productivity of land when water is scarce) is substantially increased when deficit irrigation is practiced–a widely observed and predictable response to rationed water supplies. Structured systems are most suited where water is scarce, clear definition of water entitlements is needed, management capacity is limited, and investment resources are limited. The approach to determining critical aspects of a structured system design is described in this report.

Download or read book Irrigation Training in the Public Sector written by and published by World Bank Publications. This book was released on 1989-01-01 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides guidelines for the management of irrigated agriculture to formulate long-term training policies, strategies and programs. The resulting systematic training should contribute to the improved performance of irrigation and drainage schemes and enhance the management of irrigated agriculture. The guidelines do not provide specific recommendations on how management and staff training should be organized and financed. Rather, they provide a fairly comprehensive overview of the main issues to be considered in forming a national or departmental training strategy. The main focus is on public sector irrigation organizations.

Download or read book Capacity Development in Irrigation and Drainage written by International Commission on Irrigation and Drainage and published by Food & Agriculture Org.. This book was released on 2004 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The consensus among policy-makers in the developing world and aid agencies is that a lack of capacity is constraining the development of irrigated agriculture. Although this concern is not new, it is now receiving much attention in the irrigation and drainage world, where it is becoming an issue in its own right rather than being embedded in infrastructure investment projects. In order to address this issue FAO Land and Water Development Division (AGL) organized a one-day workshop , which brought together a range of case studies from different parts of the world in order to demonstrate that capacity development should be central focus of future strategies on irrigation and drainage. This publication contains a synthesis of the workshop as well as three keynote papers prepared for the workshop based on the available literature and experiences. The complete workshop materials, which include several country papers and complementary documents, are included on a CD-ROM that accompanies this document

Available in PDF, EPUB and Kindle. Book excerpt: This report is a view of irrigation technologies for smallholders in the context of improving rural livelihoods, especially in regard to the prospects for sub-Saharan Africa. The role of traditional technologies is evaluated and modern water distribution technologies, such as sprinkler and trickle irrigation, are reviewed. A broad classification has been made based on climate and the traditional agricultural background of the local people, which links technology options to specific places--to agricultural regions and to countries.

Download or read book Private irrigation in Sub-Saharan Africa: regional Seminar on Private Sector Participation and Irrigation Expansion in Sub-Saharan Africa, Accra, Ghana, 22-26 October 2001 written by Hilmy Sally and published by IWMI. This book was released on 2011-10-21 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Only 4 percent of arable land in sub-Saharan Africa is irrigated, using just 2 percent of the available water resources. Furthermore, 18 percent of the area equipped for irrigation is not utilized at all and the intensity of use varies between 50 percent and 80 percent. This highlights the huge potential available for intensifying and expanding irrigated area, provided that the investments required can be successfully mobilized. However, it must be noted that if investments in irrigation are to yield satisfactory returns, investments must also be made in a series of related activities. Current global figures for the amount of private investment in irrigation confirm that good returns can indeed be achieved. Prospects for sub-Saharan Africa would be far more favorable if public development assistance, particularly foreign direct investments, did not show declining trends.
