Book (series)Mapping coastal aquaculture and fisheries structures by satellite imaging radar
Case study of the Lingayen Gulf, the Philippines
2004Also available in:
No results found.Inventory and monitoring of coastal aquaculture and fisheries structures provide important baseline data for decision-making in planning and development, including regulatory laws, environmental protection and revenue collection. Mapping these structures can be performed with good accuracy and at regular intervals by satellite remote sensing, which allows observation of vast areas, often of difficult accessibility, at a fraction of the cost of traditional surveys. Satellite imaging r adar (SAR) data are unique for this task not only for their inherent all-weather capabilities, very important as aquaculture activities mainly occur in tropical and subtropical areas, but essentially because the backscatter from the structure components allows for their identification and separation from other features. The area selected and object of the study has been Lingayen Gulf, sited in Northwestern Luzon Island, the Philippines, where all these structures of interest occur. F ield verification of the methodology resulted in the following accuracy: fishponds 95 percent, fish pens 100 percent. Mapping accuracy for fish cages was estimated at 90 percent and for fish traps at 70 percent. The study is based on interpretation of SAR satellite data and a detailed image analysis procedure is described. The report aims at the necessary technology transfer for an operational use of the approach indicated in other similar environments. -

Remote Sensing for Decision-Makers Series
2001Also available in:
This series, produced by the FAO Environment and Natural Resources Service, is intended for decision-makers such as heads and division directors of national and international organizations and administrations, as well as for project managers, planners and policy-makers of development institutions. Its aim is to present new possibilities of using remote sensing and geographic information system techniques to aid planning for, and management of, renewable natural resources in agriculture, forestry and fisheries. This issue is specifically intended for decisionmakers concerned with the control of vector-borne diseases and the management of rangeland resources. -
