Abstract

In the assessment of the vulnerability to sea level rise of Cagayan province in terms of rice production, data on the area harvested for rice, volume of rice production, digitized boundary maps and rice production areas, and data elevation model (DEM) were used and evaluated using Geographic Information System (GIS). GIS maps were generated based from the database obtained from the Department of Agriculture through through Bureau of Agricultural Research. The DEM was obtained from the Shuttle Radar Topography Mission (SRTM) of the National Aeronautics and Space Administration (NASA) through the consultative Group for International Agriculture Research- Consortium for Spatial Information (CGIAR-CSI). These maps were overlaid and interpolated to simulate various sea level rise scenarios at 0.25m, 1m, 2m and 3m. Results of the study showed that places near the Cagayan River delta and the South China Sea are most likely to be affected by the rising sea level. If no adaptation efforts are employed, sea level rise alone can inundate about 12% of the rice production area or lose about 65 thousand metric tons of rice in the province. Furthermore, in the municipal level, places near the Cagayan River Delta like Camalaniugan and Aparri are the area at high risk and could lose as much as 77% of its rice production area. This study proves that GIS offers a comprehensive way of analyzing and explaining different problems in the assessment of environment. It is very useful in evaluating various scenarios such as sea level rise in the Philippines, as well as other factors caused by climate change.
