DocumentLand resources information systems in the Near East
Regional workshop Cairo, 3-7 September 2001

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. -

A causal analysis of these reveals that a common element are various manifestations of spatial inequity. This most frequently includes the inequity of access rights to the resource, but factors such as variations in resource depletion, spatio-temporal variations in stock recruitment, the imposition of regulatory zoning, destruction of marine ecosystems and the siting of mariculture facilities are other example s. To resolve some of these problems, management practices must be improved. As has been shown in other fields where spatially related problems occur, there is now a promising tool, Geographical Information Systems (GIS), which, combined with other analytical tools and models, could allow for improved spatial management. GIS are basically integrated computer based systems which allow for the input of digital geo-referenced data to produce maps plus other textual, graphical and tabular output. Th e essential usefulness of GIS however, lies in its ability to manipulate data in a large number of ways and to perform various analytical functions so as to produce output which makes for more efficient decision making.As with many computer based systems, the key to GIS success lies in the acquisition of suitable data. The various means by which both primary and secondary data can be located, gathered, accessed and stored are described. Data acquisition methods vary from simple surveys, question naires and counts through to the access of secondary digital databases via on-line networking capabilities. Once data has been acquired it is only useful to a GIS when it has been formatted, processed or structured in a way which the system will understand. The various ways of doing this are introduced. GIS's can function in an almost limitless variety of configurations of hard and software. The basic elements of these are described, as are examples of some of the software packages. Before a GIS is implemented into a fisheries management programme, then there are two major areas of consideration. The first of these concerns the potential that GIS might have as a management aid. Seven potential database areas for management are described in some detail. The second area considered is that of how best to implement a marine fisheries resource GIS, along with how to ensure that sufficient guidance and support can be obtained to assure its continued success. The paper concludes with an exami nation of some case studies covering a range of marine fisheries related topics.
