The rate of global increase in water abstraction for irrigation has been declining since the 1970's due to declining potentials for large and medium-scale irrigation developments, and is expected to further decline in the next decades. As such the significant proportion of the expected increase in production would have to be supplied from existing irrigated and /or cultivated lands. This in turn could be achieved by enhancing land and water productivity through improved performance and optimal operation and maintenance.
With less than 15% of over 5 million ha irrigation potential harnessed, irrigation devolvement in Ethiopia remained low. Over 70% of the developed irrigation in the country belongs to small-scale irrigation serving smallholder farmers. While accelerated development of new irrigation, particularly of large and medium-scale schemes is relevant in Ethiopia, ensuring the performance and sustainability of existing schemes is also equally important. The existing irrigation schemes in Ethiopia are generally characterized by an overall performance and technical sustainability levels of below expectation.
This thesis evaluates the performance of two large-scale (Wonji-Shoa and Metahara) and two community-managed (Golgota and Wedecha) irrigation schemes located in the Awash River Basin of Ethiopia. The study focussed on hydraulic/water delivery performance in the large-scale schemes, and on comparative and internal irrigation service (utility) evaluation in the community-managed schemes. Water delivery performance was evaluated using routine data and hydrodynamic modelling. Farmers' utility was evaluated using qualitative responses of water users. Major performance challenges in each category of schemes were addressed and operational/water management options for improvement were identified.

Описание: This book aims at deriving governance and sustainability lessons from analysing the implementation and management of some major irrigation programs in the Mediterranean Region. Eight countries are targeted, namely: Spain, Italy, Albania, Turkey, Jordan, Egypt, Tunisia and Morocco. The main focus programs include the modernisation and rehabilitation of the existing irrigation systems, the transfer of irrigation management responsibilities to water users’ organizations, public private partnerships arrangements, the monitoring & evaluation of participatory irrigation management and transfer processes, and the governance of groundwater resources for irrigation. The adopted approach relies on learning from the value of each single experience, and on advancing solutions that emerge from their comparative analysis and that may be of guidance to those engaged in these programs. The country experiences indicated that often times, significant shortcomings in the implementation of these programs have occurred and hopefully, this book could be a source of inspiration for the corrective actions needed.

Closed circuit trickle irrigation is a form of micro irrigation that increases energy and water efficiency by using closed circuit drip irrigation systems designs. Modifications are made to traditional micro irrigation methods to reduce some of the problems and constraints, such as low compressor water at the end of irrigation lines. This approach has proved successful for the irrigation of fruit trees and some vegetable and field crops. Closed circuits of drip irrigation systems require about half of the water needed by sprinkler or surface irrigation. Lower operating pressures and flow rates result in reduced energy costs, and a higher degree of water control is attainable as well. Plants can be supplied with more precise amounts of water, and disease and insect damage is reduced because plant foliage stays dry. Fertilizers can also be applied through this type of system, which can result in a reduction of fertilizer and fertilizer costs.
This new volume in the Research Advances in Sustainable Micro Irrigation book series presents a diverse collection of research on closed circuit irrigational technology and design and provides studies of its use on such crops as wheat, maize, yellow corn, soybeans, rice, and snap peas.
The book explores:
- Soil moisture and salinity distributions under modified sprinkler irrigation
- Performance of sprinkler irrigation
- Design considerations for closed circuit drip irrigation systems
- Performance of bubbler irrigation
- Energy and water savings of drip irrigation systems
- Automation of mini-sprinkler and drip irrigation systems
- Water and fertilizer use efficiencies for drip irrigated maize
- Evaluation of emitter clogging for drip irrigated systems
This book will be valuable for those interested in irrigation planning and management, namely, researchers, scientists, educators, upper-level students, agricultural extension services, and others.
