DocumentLand resources information systems in the Near East
Regional workshop Cairo, 3-7 September 2001
2002Also available in:
No results found.This document contains the proceedings of the Regional Workshop on Land Resources Information Systems (LRIS) in the Near East, held in Cairo from 3 to 7 September 2001. The meeting was organized by FAO Land and Water Development Division (AGL) and the Near East Regional Office, in collaboration with Egypt's Executive Authority for Land Improvement Projects (EALIP). LRIS experiences in the countries are presented as well as recommendations for future collaboration in database development, reporti ng and exchange of information, expertise and experiences in land and water management in the region and the implementation of regional projects. This includes the preparation of a regional report on the state of land and water resources in the Near East for dissemination through the AGL Gateway Web site and a regional project on capacity building in LRIS for drought vulnerability assessment and mitigation in the region. -
No Thumbnail AvailableBook (series)Geographical information systems and remote sensing in inland fisheries and aquaculture 1991
Also available in:
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. -

No results found.Though Zimbabwe has few traditions as a “fish eating” nation, with the opening of Lake Kariba over three decades ago a fisheries industry was started. It has recently been realised that, in order to boost this industry, and to keep pace with the rising demands for fish, the many small dams in the country (over 12 500), which are used presently mostly for livestock and irrigation, could usefully be exploited. As well as food protein, jobs and alternative income sources would be created, especiall y in the rural communal areas. The Min. of Natural Resources and Tourism (MNR) has overall control of the larger water bodies and fisheries in Zimbabwe, and the Dept. of Agriculture, Technical and Extension Services (AGRITEX) oversees activities involving use of the small dams. It operates a small Fisheries Unit (FU) who have responsibility for fostering fisheries development. As a possible practical measure which could contribute to better management of this development, it has been suggested that a Geographical Information System (GIS) be installed. Apart from working out the most appropriate “level” for the installation of the GIS, the terms of reference (TOR) for this consultancy also sought to formulate proper objectives for a FU - GIS; to estimate the availability and quality of data obtainable; to establish the time necessary to collect and compile this; to work out whether there were advantages in adding nutritional data to a FU - GIS and to forecast the results which could b e obtained from a GIS. A total of 15 specific uses for a GIS were formulated and these would basically help to:- provide a spatially related management function, carry out development and/or planning functions, build up a temporal scenario of trends and developments.
