Book (series)African Water Resource Database. GIS-based tools for inland aquatic resource management. 1. Concepts and application case studies. 2007

No results found.The African Water Resource Database (AWRD) is a set of data and custom-designed tools, combined in a geographic information system (GIS) analytical framework aimed at facilitating responsible inland aquatic resource management with a specific focus on inland fisheries and aquaculture. It thus provides a valuable instrument to promote food security. The AWRD data archive includes an extensive collection of datasets covering the African continent, including: surface waterbodies, watersheds, a quatic species, rivers, political boundaries, population density, soils, satellite imagery and many other physiographic and climatological data. To display and analyse the archival data, it also contains a large assortment of new custom applications and tools programmed to run under version 3 of the ArcView GIS software environment (ArcView 3.x). The database allows integration of different types of information into a cohesive program that, because of its visual nature, is easy to underst and and interpret. Creative applications of these tools and data could deepen our understanding of inland aquatic resource management and be of immediate value in addressing a wide variety of management and research questions. The AWRD was designed based on recommendations of the Committee on Inland Fisheries for Africa (CIFA) and is both an expansion and an update of an earlier project led by the Aquatic Resource Management for Local Community Development Programme (ALCOM) entitled the “S outhern African Development Community Water Resource Database” (SADC-WRD). The AWRD publication is organized in two parts to inform readers who may be at varying levels of familiarity with GIS and with the benefits of the AWRD. The first part describes the AWRD and is divided into two main sections. The first presents a general overview and is addressed to administrators and managers while the second is written for professionals in technical fields. The second part is a “how to” supplement and includes a technical manual for spatial analysts and a workbook for university students and teachers. The primary AWRD interface, tool-sets and data integral to the function of the AWRD are distributed in two DVD’s accompanying part 2 of this publication, and are also available for download from FAO’s GeoNetwork and GISFish GIS portals. A more limited distribution of the above primary database/interface, but divided among ten separate CD-ROM disks, is available upon request to FAO’s Aqu aculture Management and Conservation Service. Also, high resolution elevation datasets and images amounting to 38 gigabytes are available upon request. -
Book (series)Geographic information systems in fisheries management and planning. Technical manual 2003
Also available in:
No results found.The FAO Inland Water Resources and Aquaculture Service (FIRI) has been active in promoting the use of geographic information systems (GIS) and remote sensing in fisheries and aquaculture since 1985. However, a manual to use along with GIS software for the fisheries biologists in the field explaining GIS in a way that is understandable to non-GIS users had not been produced until now. This manual was written to overcome this knowledge-gap, it is a “do-it-yourself-manual” giving a short introducti on to GIS software and its applications in fishery science. The overall objective of this manual is to encourage fishery managers to use GIS to foster the sustainable use of natural resources. It is aimed at fisheries biologists, aquatic resource managers and decision makers in developing countries who have no knowledge about GIS. The manual is useful for a broad range of fishery applications. Although the manual by no means covers all possibilities of GIS, it touches upon some of the most impor tant features for fisheries management and planning. -

The rapidly rising world population is causing both a pressure on land and water space and the need to greatly increase food output. A realistic and practicable way of supplying more food protein is to increase fish production through the extension of aquaculture and inland fisheries. Since production sites for these activities need to satisfy fairly complex location criteria, it is important that suitable areas are identified and preferably designated in advance. The location criteria which con trol aquaculture and inland fisheries are identified and described. These mainly consist of physical and economic considerations though social factors may be important. It is necessary to obtain data to allow for its mapping. The various alternatives for assembling this data are described. Two fields of applied science and technology have recently emerged which, when used in combination, can greatly assist in the spatial decision-making process. The fundamentals of the first of these, remote sensing, are described giving particular emphasis to the commercial, high resolution environmental satellites and the sensing devices which they carry. The manner in which the aerial photographic and digital images which are produced can be processed and applied to the search for optimum fish production locations is described, and then indications are given as to where and how remotely sensed data can best be procured. Once the various types of locational data are assembled, the necessary maps o n which location decisions are made can be drawn up. This task can be greatly expedited by using the second applied science and technology field, that of “geographical information systems”. This emerging methodology relies on the increasing power of the computer to process vast amounts of spatially referenced and encoded data in such a way as to produce any desired maps, tabular or textual output, using a large array of ways to manipulate the data. The required computer hardware and software are reviewed, including examples where appropriate, and we show the considerations which are necessary in setting up a geographical information system for the development and management of aquaculture and inland fisheries. We conclude by giving an divergent selection of relevant case studies.
