Improving agricultural water use efficiency (WUE) is vitally important in many parts of the world due to the decreasing availability of water resources and the increasing competition for water between different users. Micro irrigation is an effective tool for conserving water resources. Studies have revealed a significant water savings, ranging from 40% to 70% under drip irrigation compared with surface irrigation. This new volume, Engineering Interventions in Sustainable Trickle Irrigation: Irrigation Requirements and Uniformity, Fertigation, and Crop Performance, presents valuable research that evaluates crop water and fertigation requirements, examines optimum irrigation and fertigation scheduling, and analyzes the performance of agricultural crops under micro irrigation.
With an interdisciplinary perspective, this volume addresses the urgent need to explore and investigates the current shortcomings and challenges of water resources engineering, especially in micro irrigation engineering. The volume discusses crop water requirements, fertigation technology, and performance of agricultural crops under best management practices. The chapter authors present research studies on drip irrigated tomato, chilies, cucumber, eggplant, cabbage, garlic, sugarcane maize, cashew nut, sapota, banana, mango, and blueberries.
Removing the research gap, this volume provides new information that will be valuable to those involved in micro irrigation engineering.
Название: Climate Change Risk and Adaptation Assessment for Irrigation in Southern Viet Nam: Water Efficiency Improvement in Drought-Affected Provinces ISBN: 9292625071 ISBN-13(EAN): 9789292625078 Издательство: Mare Nostrum (Eurospan) Рейтинг: Цена: 20070.00 T Наличие на складе: Есть у поставщика Поставка под заказ. Описание: It highlights new developments and key lessons on climate risk assessment that may be applied to the project design and monitoring as well as the implementation of climate adaptation measures. The WEIDAP project was developed in response to the drought that affected southern Viet Nam in 2015–2016. It focused on irrigation modernization and the integration of climate-resilient agricultural and efficient on-farm water management practices.

Описание: Discusses various components of the water balance of an irrigated area including: evapotranspiration, effective precipitation, and capillary rise from the groundwater table. This book combines the components into a water management strategy that balances evapotranspiration (and thus crop yield) with the groundwater balance of the irrigated area.
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 focuses on irrigation sources together with water management for agricultural development in Uttar Pradesh state of India. Being the most populous state of the country, it bears a burden of feeding about 199 million people of which major section relies on agriculture for their subsistence. This study makes comparison in the growth trends in the irrigated area, crop land use patterns and crop productivity at the district level in different periods of time. The book emphasizes on irrigation water management to optimize crop yields in order to increase Water Productivity of crops in low productivity regions of the state applying suitable technology.This book appeals to researchers and students in geography and planning working on the topics of agriculture as well as irrigation and water management aspects.

Описание: Over 100 irrigation projects and systems can be found on Indian reservations primarily across the western United States. The scarcity of water in much of the western United States makes irrigation critical to agricultural activities. The Department of the Interiors Bureau of Indian Affairs (BIA) manages 16 irrigation projects on Indian reservations in the western United States. This book focuses on BIAs estimated deferred maintenance cost for its irrigation projects; shortcomings that the Government Accountability Office (GAO) identified in BIAs management of its irrigation projects; and issues GAO identified that needed to be addressed to determine the long-term direction of BIAs irrigation program.
