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.

Описание: Over the last three decades drought episodes have resulted in severe social problems in Mediterranean countries, receiving broad attention from the international scientific and policy communities. The experiences in the development and implementation of drought management plans highlight the success and challenges of coping with drought for societies with different vulnerabilities and emphasize risk-based drought management as a critical approach to mitigate the impacts associated to drought-induced water shortages. Based on these experiences and the current methods for evaluating risk, the book synthesises guidelines for drought management that link science and policy and that can be applied to other regions. The book comprises a collection of papers divided into four sections that appeal to a broad audience. First, the social and hydrological context of Mediterranean countries is presented, discussing the interactions that have resulted in the complex institutional framework, and highlighting the importance of stakeholder involvement and awareness building for successful drought management. This section emphasises the role of organizations, institutions, and civil stakeholders involved in drought preparedness and mitigation and/or on water management for designing effective risk based strategies that mitigate the effects of drought in agriculture and water supply systems. Second, the book presents an academic approach to risk evaluation, including characterization of drought episodes, development of indicators of risk in hydrological and agricultural systems, and analysis of the role of economic instruments and groundwater for risk mitigation. This section finalises with the description of an integrated method for evaluating social vulnerability based on indicators that include the capacity to anticipate, cope, and respond to drought. The third section includes a collection of case studies that include the description of effective measures taken in the past. These case studies provide the context for developing demand driven guidelines that may be applied to other regions. The authors of these chapters can be viewed as stakeholders in drought management, since they represent a broad range of sectors and institutions from Mediterranean European and North African countries. The topics addressed have implications for the international policy community interested in disaster mitigation, agricultural policy, and development. Finally a synthesis of the management actions is presented in four chapters. Monitoring and preparedness planning is the essential first step for moving from disaster to risk management in response to drought. The management actions related to agriculture and water supply systems are presented in two different chapters but with a common conceptual framework based on the use of drought indicators for evaluating the levels of drought risk (pre-alert, alert, and emergency), that allow establishing linkages between science and policy. The final chapter discuses the lessons learned and application to other regions.
Название: Watershed Management in Action: Lessons Learned from FAO Field Projects ISBN: 9251300143 ISBN-13(EAN): 9789251300145 Издательство: Mare Nostrum (Eurospan) Рейтинг: Цена: 76690.00 T Наличие на складе: Невозможна поставка. Описание: Watershed management has gained momentum over the past decade as a holistic way of conserving water, land and biodiversity resources while sustaining livelihoods. This publication looks at how 12 projects in Africa, Asia and Latin America are using the approach to devise local solutions to global challenges. In Ecuador’s Mount Chimborazo for example, pilot schemes were put in place to compensate upstream inhabitants for sustaining ecosystem services, targeting users such as the hydroelectric company and flower nurseries. In Pakistan’s earthquake-affected areas, a watershed management project contributed not only to the rehabilitation of roads and irrigation channels but also to the diversification of food and income sources. These and other examples are presented in the publication, which looks at both the strengths and weaknesses of the approach and highlights the need for stronger governance and long-term sustainability.
Название: Sampling and Isotope Analysis of Agricultural Pollutants in Water ISBN: 9201050186 ISBN-13(EAN): 9789201050182 Издательство: Mare Nostrum (Eurospan) Рейтинг: Цена: 17550.00 T Наличие на складе: Невозможна поставка. Описание: Stable isotope techniques can help identify the sources of water pollution associated with agricultural activities. Knowing the origin of nutrients or contaminants is essential to improve agricultural practices. To ensure the quality of stable isotope analysis, appropriate sampling and sample preparation are crucial. This publication presents methods for surface water sampling and sample processing through micro-diffusion and bacterial denitrification combined with laser spectroscopy. Information on such methods is often described in a very summarized and non-comprehensive way without proper illustration of every step. This publication aims to bridge this gap for scientists, technicians and students. It presents a selection of standard operating procedures providing guidance in water sampling and sample preparation that are mandatory when conducting reliable isotope analysis on water.

Описание: Dry areas suffer not only from limited rainfall but also natural leakage90% of rainwater is lost directly or indirectly, and is unavailable for agriculture or domestic use. Water harvesting is a low-cost, easy-to-use, environmentally-friendly way to recover a large part of this lost water. There is a need of a more efficient capture and use of the scarce water resources in low rainfall areas. An optimization of the rainfall management, through water harvesting in sustainable and integrated production systems can contribute for improving the small-scale farmers livelihood by upgrading the rainfed agriculture production. This book is a review of simple and chip water harvesting techniques, which have been tested and found useful somewhere, and which might be suitable for use in other conditions. The book also tries to show some successful cases of application of water harvesting techniques in low rainfall areas, which have increased the overall productivity of smallholder farm and hence improved farmers livelihood.
