Book Description
The aim of this paper is to facilitate the planning and design of land drainage systems for sound land and water management for engineers and other professionals. It considers the integration of technical, socio-economic and environmental factors and the need for system users' participation in the planning, design, operation and maintenance processes. The text provides guidelines for the appropriate identification of drainage problems, for the planning and design of field drainage systems (surface and subsurface) and the main drainage and disposal systems. The annexes provide more detailed information with technical background, appropriate equations, some cross-references for finding appropriate methodologies, and computer programs for calculation of extreme values, of permeability and some land drainage system parameters. --Publisher's description.

Book Description
Modern Land Drainage 2nd edition is a fully revised and updated edition of the 2004 edition. Modern Land Drainage describes traditional drainage formulas (Hooghoudt, Kirkham, Donnan, Ernst, Glover-Dumm) for rainfed agriculture in the humid temperature zone. Significant parts are devoted to drainage for salinity control of irrigated land in (semi-) arid zones, and to drainage of rice land in the humid tropics. Institutional, management and maintenance aspects are extensively covered, as well as the mitigation of adverse impacts of drainage interventions on the environment. The latest computer applications for drainage design in the context of integrated water management are described (DRAINMOD, HEC, SWAP, etc.). Field surveys are executed by governments, with the aid of consultants, but rarely are the end stakeholders (i.e., farmers and general public) involved from inception to planning to execution of a drainage system. Yet, during the Operation, Management and Maintenance (OMM) phase of a water management system, they are expected to takeover, run, bear and be responsible for the costs of OMM. The book describes successful methodologies and processes to be followed for engagement of stakeholders at all levels, from government to farm, from minister to farmer, and, from beginning to end. The book covers all aspects needed for sustainable drainage. The latest survey methodologies with satellites and drones are suggested to assess cause and effect. Waterlogging and salinity are the effect of something caused most likely upstream of the drainage problem location. Hence treating the cause may be more cost-effective. Triple Bottom Line (social, environmental and financial considerations) and the water-food-energy nexus are an integral part of the drainage design process. Controlled drainage, i.e. the balance of removal and conservation of drainage water and minimising solute transport as low as reasonably achievable (ALARA principle) is extensively described. This work is intended for use both as a university level textbook and as a professional handbook; it is of particular value to professionals engaged in drainage development in the context of integrated water resources and river basin management, civil and agricultural engineers, government officials, university students and libraries.

Book Description
This publication describes the MASSCOTE methodology, illustrated by several applications in Asia. MASSCOTE is a comprehensive methodology for analysing the modernization of canal operation. The aim is to enable experts to work together with users in determining improved processes for cost-effective service-oriented management. It is based on previous tools and approaches widely used in Asia by FAO in its modernization training programme (rapid appraisal procedures and benchmarking). From diagnosis through the formulation of operational units and the planning of a service (based on the vision agreed upon with the users), MASSCOTE entails a systematic, ten-step, mapping exercise. The accompanying CD-ROMs contain the full document in English, excerpts in French, a draft version in Arabic and Chinese, training presentations and material, and a number of documents and references on irrigation system operation and management [System requirements: PC with Intel Pentium(r) processor and Microsoft(r)Windows 95/98/200/Me/NT/XP; 256 MB of RAM; 50 MB of available hard-disk space; SuperVGA monitor; 256 colours at 1024x768; Adobe Acrobat(r) Reader (not included on CD-ROM)]

Book Description
Irrigation has been and will continue to be an agricultural and rural investment priority. Development of the irrigation sector faces multiple challenges, including water scarcity and degradation, competition over shared resources, and the impact of climate change. Innovations are needed to address these challenges, as well as emerging needs, and to promote productive, equitable and sustainable water management. These guidelines, produced by an inter-agency team, highlight experiences and lessons learned from global irrigation investment operations. They introduce innovative approaches, tools and references, and provide practical guidance on how to incorporate or apply them at each stage of the investment project cycle. The guidelines will be a useful resource for national and international professionals involved in irrigation investment operations.

Book Description
Modern agriculture faces many challenges, most crucially food security and the need for sustainable farming systems. Decisions and actions in the agricultural sector come from government and stakeholder policies and on-farm decision-making. This comprehensive monograph provides a perspective on the current state of agri-environmental management in Europe from both a policy and practical perspective. Some of the issues in agriculture discussed are climate change and air pollution, biodiversity, water use and quality, pesticides, pathogens, flooding and drought, energy resources, land use, soil composition, nutrients, livestock, cropping, habitat management and cultural considerations. These important issues form the framework of the book, with each issue discussed in the context of its history, and asking the questions 'why is it an issue', 'what is the current scientific understanding regarding it' and 'how has policy shaped it'. The book takes an integrated approach by not just examining these issues separately, but examining the whole system in which these problems are manifested. At the end, technologies and solutions which are currently being developed and could be used in the future are discussed and the horizon scanned for future environmental challenges. Agri-environmental Management in Europe is an authoritative source for both undergraduate and post-graduate studies that consider the agri-environmental challenges society faces.

Book Description
Loquat (Eriobotrya japonica Lindl.) is a subtropical evergreen fruit tree indigenous to China. Records show it has been cultivated in China for over 2000 years. From this beginning, loquat has spread to more than 30 countries around the world. Grown in various regions of Asia, the Mediterranean and across the Americas, loquats suit both temperate and subtropical areas, sharing the same environmental conditions as citrus. Loquat is an increasingly commercial crop in some Asian and European countries with a good amount of international trade. This book is to be the first to provide a comprehensive coverage of the history, physiology, culture and marketing of loquat throughout the world.

Book Description
Reliable subsurface drainage systems for groundwater table and salinity control are needed to maintain or enhance the productivity of irrigated lands and to contribute to the rural development of lowlands in the humid tropic. This publication presents guidelines to assess the need for envelopes and for the selection of appropriate materials (i.e. pipes and envelopes) for the proper and lasting performance of subsurface drainage systems. In addition, it also contains guidelines for adequate installation and maintenance of drainage materials as well as the required specifications and standards of such materials, which may be used in tender documents for implementation of subsurface drainage works. Practical guidelines for the implementation of laboratory and field investigations to evaluate the performance of drainage materials have also been included.--Publisher's description.
