Download or read book Methodology for the Evaluation of Performances of Irrigation Systems from Farmers Perspective written by J. Rodríguez Ros and published by . This book was released on 2013 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluations of performances of irrigation systems in developing countries have been traditionally performed by technical experts, based on agronomic, engineering and other technical aspects. Given the little attention paid to the social dimension of irrigation, experts failed to meet the real causes behind low performances of irrigation schemes, being therefore unable to implement adequate solutions. In order to identify and tackle the base problems of irrigation systems, farmers are placed at the center of the evaluation, taking into account their key role of irrigation systems as clients and producers. Thus, this study aims to gain scientific insight into the evaluation of performances of irrigation systems from farmers’ perspective, reflecting on a new methodological approach that can be useful to effectively identify the main problems faced by farmers and the solutions implemented by them. The methodology developed has been tested in the irrigation schemes of Gumselassa and Betmera, in the Tigray Region, Ethiopia, analyzing farmers’ perception over the social, economic and technical dimensions of irrigated agriculture. More specifically, farmers participated in the development and implementation of an opinion poll based on a grid of 21 indicators, as well as in the analysis of the results through two WUA meetings. This allowed for further characterization of the innovations identified, one of the main objectives of the Project EAU4Food.

Download or read book Analyzing Irrigation District Water Productivity by Benchmarking Current Operations Using Remote Sensing and Simulation of Alternative Water Delivery Scenarios written by Jonna D. van Opstal and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigation systems are designed to deliver water to crops, but their efficacy varies widely due to operational decisions, weather variability, and water availability. The operation of an irrigation system is studied in this dissertation to determine irrigation performance and potential for improvement.Satellite remote-sensing was used to determine inter-annual variability in crop evapotranspiration and link it with weather patterns and operational decisions. A decade was studied to include several dry, wet and average years of snowfall. It was found that the irrigation district has the capacity to buffer a dry year, but crop evapotranspiration patterns indicated that the buffer capacity of the irrigation district is limited in a second dry year. Studying the current operations of an irrigation system also requires an analysis of the spatial variability within the system to identify potential areas for improvement. Achieving such information is challenging due to the spatial heterogeneity between farm fields. The Ador irrigation system simulation model is used in this study with satellite remote sensing data, which were combined in the calibration and validation process to ease the re-adjustment of management parameters. This approach provides a cost-effective and innovative method for model simulation when field observations are limited. Alternative water delivery scenarios were simulated with the Ador irrigation system simulation model to quantify changes in the water balance, irrigation performance, and water productivity. Results for implementing a minimal irrigation time indicated that irrigation events occurred with a higher frequency and reduced crop water stress. Water productivity for the irrigation district increased substantially in this scenario, whilst district water savings were achieved by diverting less irrigation water. Advantages are only achieved if farmers collectively make the decision to change. A water accounting analysis is required to examine if water savings are achieved at basin scale. There is a potential for the rebound effect to occur, which suggests that an increase of water efficiency causes the increase of water consumption. Simulation results indicated that if the efficiency is increased through improvements of the water delivery, the water consumption increased. Water savings achieved by reducing irrigation diversions did not compensate for the decrease in drainage that downstream users depend on.

Download or read book The Hindu Kush Himalaya Assessment written by Philippus Wester and published by Springer. This book was released on 2019-01-04 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access volume is the first comprehensive assessment of the Hindu Kush Himalaya (HKH) region. It comprises important scientific research on the social, economic, and environmental pillars of sustainable mountain development and will serve as a basis for evidence-based decision-making to safeguard the environment and advance people’s well-being. The compiled content is based on the collective knowledge of over 300 leading researchers, experts and policymakers, brought together by the Hindu Kush Himalayan Monitoring and Assessment Programme (HIMAP) under the coordination of the International Centre for Integrated Mountain Development (ICIMOD). This assessment was conducted between 2013 and 2017 as the first of a series of monitoring and assessment reports, under the guidance of the HIMAP Steering Committee: Eklabya Sharma (ICIMOD), Atiq Raman (Bangladesh), Yuba Raj Khatiwada (Nepal), Linxiu Zhang (China), Surendra Pratap Singh (India), Tandong Yao (China) and David Molden (ICIMOD and Chair of the HIMAP SC). This First HKH Assessment Report consists of 16 chapters, which comprehensively assess the current state of knowledge of the HKH region, increase the understanding of various drivers of change and their impacts, address critical data gaps and develop a set of evidence-based and actionable policy solutions and recommendations. These are linked to nine mountain priorities for the mountains and people of the HKH consistent with the Sustainable Development Goals. This book is a must-read for policy makers, academics and students interested in this important region and an essentially important resource for contributors to global assessments such as the IPCC reports.

Download or read book Irrigation Performance Evaluation written by Melisew Misker Belay and published by LAP Lambert Academic Publishing. This book was released on 2012-01 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal objective of surface irrigation systems evaluation is to identify management practices and system configurations that is feasible and effective to improve irrigation efficiency. Evaluation plays a fundamental role in improving surface irrigation systems by providing the information required for design, model validation and advising irrigators on how to improve their systems and management practices. The technical performance of the schemes was evaluated by considering conveyance efficiency, application efficiency, dependability of irrigation interval and sustainability of irrigation.Moreover, availability of institutional and support services, market availability and conflict management were investigated through questionnaire administered to beneficiary farmers and other stakeholders. The conveyance loss in Sanka traditional irrigation is greater than Golina modern irrigation scheme but in Sanka participation of farmers and sense of ownership is rated to be 100%.Therefore, if proper canal and canal structures are in place and water users associations are empowered more in order for it to enforce its bylaws it will augment the efficiency of the scheme exceedingly.

This book was released on 2012 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report investigates the dynamics of one of the most common agricultural water management practices of sub-Saharan Africa, i.e., small reservoirs. Small reservoirs dam permanent or temporary river flows and support multiple livelihood activities (livestock watering, crop cultivation, fisheries, small handicrafts, etc.) while providing water-related ecosystem services (soil and water conservation, flood and drought mitigation, etc.). Gathering evidence from four sub-Saharan countries, Burkina Faso, Ghana, Ethiopia and Zambia, this report calls for revisiting our understanding and assessment of the costs, performance and institutions for the management of small reservoirs. A more holistic analytical approach is the first step towards an integrative governance framework. This, in turn, holds the promise of sustainable management of small reservoirs.
