The Lingayen Gulf Coastal Area Management Plan (NEDA, Region I 1992) completed under the ASEAN/US Coastal Resources Management Project in late 1991 recommended that a zonation scheme be established for Lingayen Gulf. It noted the numerous resource use conflicts in addition to resource over-exploitation and diminution of socioeconomic benefits for the coastal fisherfolk. The zonation scheme would be one of the several options aimed at sustainable development of the Lingayen Gulf area resources. At the onset of the GISCAMP Project, it was envisaged to use geographic information systems (GIS) for spatial data management and to develop application modules relevant to coastal area management and planning. The recommendation of the plan for a zonation scheme made it necessary to enlarge the scope of the project. A draft zonation scheme was completed in early December 1993 and further refined after a national workshop held sometime in mid-December. This report covers the evaluation of the zonation scheme by the regional technical representatives of key agencies in Region I including the academe. It was held at the Miramonte Resort, Poro Point, La Union on 18 January 1994.
