Mapping the Pacific Coastal Populations

At the 2017 CSI Meeting in Cali, Shwu Jiau Teoh from WorldFish presented a recent collaborative study with the Pacific Community (SPC) on the mapping of coastal populations in the Pacific Island countries. People who live closer to the coast in these countries are more dependent on the sea for livelihoods and thus more exposed and sensitive to the natural disaster threats, yet there hasn’t been an accurate spatial data to show how many they are, where. This new initiative combines two global population databases, Landscan and GPW, with census and groundtruthing data on the size and location of households.

Coastal buffer zones of 1km, 5km and 10km was created using GAUL

Preliminary results of this study is available through ArcGIS Story Map ( Learn more about the methodology and other geospatial work at WorldFish from Shwu’s presentation: Shwu Jiau Teoh (WorldFish) 2017 – Center Update – CGIAR-CSI in Cali (Sep 22)
