West Africa Coastal Vulnerability Mapping: Economic Systems Index

The West Africa Coastal Vulnerability Mapping: Economic Systems Index is a composite index based on several spatial indicators, including gridded Gross Domestic Product (GDP), nighttime lights as a proxy for urban built-up and industrial areas, and cocoa, coconut, palm oil, rubber, and banana production in metric tons. It covers the coastal region of West Africa within 200 km of the coast. Population growth in the coastal zone is mostly a function of migration related to coastal economic activities; this indicator provides insights into highly exposed coastal areas that not only have high levels of economic activity but also high population growth and migration.

西非沿海地区脆弱性映射：经济系统指数是一项基于多个空间指标的综合指数，这些指标包括网格化的国内生产总值（GDP）、夜间灯光作为城市建成区和工业区的代理，以及可可、椰子、棕榈油、橡胶和香蕉的产量（单位：公吨）。该指数覆盖了西非沿海地区，范围在海岸线200公里以内。沿海地区的 population growth（人口增长）主要受与沿海经济活动相关的 migration（迁移）影响；此指标为深入分析那些不仅经济活动活跃且人口增长迅速、迁移频繁的高度暴露的沿海地区提供了洞见。
