River Variability and Complexity presents a new approach to the understanding of river variability. It provides examples of river variability and explains the reasons for them, including fluvial response to human activities. Understanding the mechanisms of variability is important for geomorphologists, geologists, river engineers and sedimentologists as they attempt to interpret ancient fluvial deposits or anticipate river behavior at different locations and through time. This book provides an excellent background for graduates, researchers and professionals.br � A concise new approach to the understanding of river variability, building on the author's 40 years experience of river geomorphology br � Includes helpful reference tables and charts for the study of river characteristics (type) and behaviour (dynamics) br � Includes a discussion of the unintended consequences of human actions and develops a hypothesis regarding the effect of river characteristics on human behaviour
This overview of fluvial geomorphology provides river engineers and managers, who may lack specialist training in this field, with useful insights into, and understanding of, natural channel forms and fluvial processes. Such information is a pre-requisite for carrying out environmental impact assessments and for developing environmentally sensitive design and management procedures to preserve riverine environments and restore degraded ones. Designing with nature is preferable to imposing hard engineering solutions as it sustains natural biodiversity and minimises costs. This book will also be an invaluable teaching aid for students, both under- and postgraduate, studying civil engineering, environmental management or sciences, or geography who are looking to have a wider knowledge of new approaches to the subject. Geomorphology requires the collection and consideration of a wide range of data, mostly field based but also including historical information such as archive documents and maps, which are outside the experience of most river engineers and managers. These data enable the current condition of the river to be explained, both locally and within the catchments and establish historical changes and future trends. In addition, process studies have now identified many of the mechanisms controlling river morphology which underpin the development of soft, bio-engineering, design procedures. The book incorporates material on methods and techniques of data collection, analysis and interpretation, making extensive use of case studies throughout. Thus the experienced authors go some way towards demystifying applied fluvial geomorphology by demonstrating that, while there is still an element of judgement, major contributions to geomorphic understanding usually come from the careful assemblage and objective analysis of all available data and information.
The objective of the study is to asses the problems, opportunities, priorities and the constraints of the Somalia's rural sector, to develop a strategic approach towards medium to long-term support and investment provided by donors to the marginal rural areas to northern and central Somalia and to avail the technical documents for the tendering of related intervention programmes()
In The ESRI Guide to GIS Analysis, Volume 2: Spatial Measurements and Statistics, Mitchell (the author) takes users deeper, showing how an emerging set of tools that rely on spatial statistics provides GIS users the capability to conduct detailed, mathematical analysis of geographic information, This second volume introduces statistical tools, geared specifically for geographic analysis, that are relatively new to GIS software packages and thus to most GIS users. It shows the tools in use in many different applications, explains which tools are best with which situations, and provides guidance on interpreting the results you get. The ESRI Guide to GIS Analysis, Volume 2: Spatial Measurements and Statistics focuses on four fundamental tasks of statistical analysis. These are: calculating the center, dispersion, and trend, Identifying patterns, Identifying clusters and Analyzing geographic relationships.
This handbook makes available information on the most useful trees and shrubs in Kenya. It provides valuable information on on a wide variety that are important to farmers, pastoralists and other people. The trees and shrubs covered may be used for food , medicine, forage, timber and many other purposes. contents of the book are arranged an easily accessible format. The comprehensive species descripions are supplimented with lists of common names in many Kenyan languages and lists and indexes of scientific names. the book will be helpful for extensive agents at all levels for those n educational research institutions and for anyone interested in growing and managing trees and shrubs, whether to develop a sustainable farming system, restore the environment, or to engage in growing trees aas a bussiness.
The Toolkit, managed by the Technical Cooperation Department (TC), is designed to facilitate the formulation of projects under the FAO supported Special Programme for Food Security (SPFS), the Technical Cooperation Programme (TCP) and TeleFood, as well as under Trust Fund arrangements. Its content is organized into five clusters: andrdquoProject Categoriesandrdquo, andrdquoFunding Sourcesandrdquo, andrdquoSPFSandrdquo, andrdquoUseful Information and Referencesandrdquoand andrdquoLessons Learnedandrdquo, each with distinct characteristics. Introductory texts to each subject provide a general context and key issues concerned, with links to further information.
Across Africa's rural areas, reliable water supply is at the root of all sustainable development. In the hands of motivated technical advisors of well organissed community groups, this manual holds the promise to increasing the vital water resources. In consise and readable language, 'water form pans and ponds' guides the reader through all stages of community planning, design and construction, maintenace and operation of these water storage structures. Every chapter is illustrated with figures that add to the text. At the back of the book, you'll find a kit of practical tools on how to plan, survey sites, analyse soil properties, determine water needs and estimate construction costs. This book is meant to help improve water supply for rural communinties throughout East Africa.
The present project is a further development of an initial intervention by GAA in the Dur-Dur Valley. This second phase seeks to contribute to the stabilisation and improvement of rural livelihoods in Awadal region based on the sustainable use of natural resources. The project area covers the entire Dur-Dur watershed, which is situated within the Districts of Borama, Baki and Lughaya. The project is designed to enable communities in the watershed to manage natural resources and farming systems increasingly in a sustainable, efficient and equitable manner. A major investment of the project is to develop an Integrated Water Resource Management Plan (IWRMP) in close collaboration with land-users and administrative bodies.
The FAO Somalia Water and Land Information Management (SWALIM) Stakeholders Workshop was held at the Nairobi Serena hotel on 15th September 2005 and was attended by about 60 representatives from United Nations agencies, Non governmental organisations and community based organisations with experience in water and land related development issues in Somalia.
