Book (stand-alone)Fish passes. Design, dimensions and monitoring. 2002(Originally published in German by Deutscher Verband für Wasserwirtschaft und Kulturbau e.V.) Many fish species, like salmon and sturgeon, undertake extended migrations as part of their basic behavior, and other fish and invertebrates also undertake short-term or small-scale migrations at certain phases of their life cycles. Activities such as dam construction for water supply and power generation, channelization for navigation and flood control, land drainage and wetland reclamation for agricul tural and urban use all have profound impact on the aquatic ecosystem and thus on natural fish populations. Fish passes are often the only way to make it possible for aquatic fauna to pass obstacles that block their up-river journey. Based on knowledge and experience from mainly Europe and North America, this book describes the various types of fish passes, with special emphasis to "close-to-nature" solutions. It is hoped that this book contributes largely to increase the awareness of the need f or unobstructed fish passage and to multiply the number of well-designed and well-dimensioned fish passes around the globe to restore lost migration routes.

Book (stand-alone)Optimizing soil moisture for plant production
The significance of soil porosity
2003Also available in:
This publication discusses the processes above, within and below the soil that enable water to move and crops to grow, and is intended to help land users make better use and take better care of these basic resources. The document will contribute to raising awareness of possibilities for better use of rainwater and improved management of soils. It will be useful to anyone concerned with maintaining and improving the productivity, quality and health of land, including farmers, advisory staff, trai ners and their students, as well as technical decision-makers in governmental and non-governmental agencies. It should also encourage multidisciplinary approaches and dialogues among stakeholders of different backgrouds. -
Book (stand-alone)Capacity development in irrigation and drainage
Issues, challenges and the way ahead
2004Also available in:
No results found.General consensus among policy-makers in the developing world and aid agencies is that a lack of capacity is con-straining the development of irrigated agriculture. Although this concern is not new, it is now receiving much attention in the irrigation and drainage world where it is becoming an issue in its own right rather than being embedded in infrastructure investment projects. To address this issue, FAO Land and Water Development Division, in association with the International Commission o n Irrigation and Drainage (ICID) Working Group on Capacity Building, Training and Education, organized a one-day workshop, Capacity Building in Irrigation, Drainage and Flood Control, on 16 September 2003 during the Fifty-fourth International Executive Council Meeting in Montpellier. This publication presents a synthesis of the workshop as well as three keynote papers based on the available literature and experiences. The complete workshop materials are included on the CD-ROM that accompanies th is document. It is anticipated that the wealth of information supplied here will provide background for those people contemplating capacity development in irrigated agriculture in their own country.
