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. -
ProjectEnhancing Land and Water Productivity in Africa and the Near East through Remote Sensing Technology - GCP/INT/229/NET 2021
Also available in:
All countries in North Africa and the Near East suffer from severe water scarcity. In this region, irrigated agriculture accounts for a large proportion of the water demand and is often the first sector affected by water shortages and scarcity. Notably, when water is in short supply, there are additional challenges for sustaining per capita food production and meeting domestic, industrial and environmental water needs. Further complicating matters, the total area suffering from severe water scarcity is expected to increase as a result of changing climatic conditions. Increasing water scarcity and competition for water resources also pose major threats to food security and poverty alleviation. If the effects of climate change are not managed effectively, more frequent and extensive periods of drought are expected, creating additional challenges for maintaining the balance between water demand and sustainable development. Despite the agriculture sector being a primary consumer of water, irrigation services and scheme performances have not been fully optimized in the region and best management practices and technologies have not been widely deployed. As such, this project was designed to support countries in monitoring land and water productivity, identifying productivity gaps and developing suitable solutions. -
No Thumbnail AvailableBook (stand-alone)Preparation of Land Cover Database of Bulgaria through Remote Sensing and GIS 2001
Also available in:
No results found.Land cover maps constitute a necessary tool for development planning and management of the territory. Furthermore, land cover maps depicting the current reality are a must in countries where, due to political changes, rapid dynamic phenomena have taken place, resulting in a complete restructuring of the agricultural and other sectors, as in the case of Bulgaria. The scale of such maps should be large enough to provide detailed information, however it should allow for regional assessment, st atistics and subsequent planning. The 1:50 000 scale is the most suited for this exercise. The FAO project TCP/BUL/8922 “Strengthening Capacity in Agricultural Development through Remote Sensing and GIS” has produced 14 land cover maps at 1:50 000 scale for selected test areas of the country, covering 5 600 sq km. These maps were prepared using Landsat satellite data, acquired in 1998 and 1999 as the main data source and thus represent the land cover existing at that time. The land cover cl assification was performed using the FAO Land Cover Classification System (LCCS). To each mapped unit (polygon), soil type and erosion features were linked as attributes into the GIS system. This created a comprehensive database, which is unique in Bulgaria. The database provides very useful information for agriculture, forestry and urban development planning, for environment protection and for many other applications. The data collected in the database provide the possibility for different kinds of spatial analysis, which is necessary in land management. For an area of particular interest, IKONOS very high resolution satellite data were used to produce an assessment of the state of vineyards, the updating of the linear features of a large scale topographical map and other applications. The methodology and applications reported in this study have been tested and refined under operative conditions in the framework of the project’s activities.
