CSPI map

This map visualizes the Carbon Sequestration Potential Index (CSPI) of Okinawa in GEE.

The Carbon Sequestration Potential Index (CSPI) visualizes the potential for above-ground carbon sequestration in a given area. This potential is influenced by several factors, including Gross Primary Production (GPP), Aboveground Carbon Density (ACD), and Forest Cover (FC). GPP is the rate at which carbon dioxide is fixed from the atmosphere through photosynthesis, ACD is the amount of carbon stored above ground, and FC represents the percentage of the area covered by forests, focusing on forested regions.

To create this map, data for Okinawa was first downloaded from the government website, including shapefiles and GeoTIFF files containing the coordinates. This data was then processed using preprogrammed Google Earth Engine (GEE) code to apply the GPP, ACD, and Forest Cover functions. The result is an interactive GEE map displaying individual ACD and GPP values.

The map covers Okinawa, a Japanese island characterized by coral reefs, rugged coastlines, sandy beaches, and hilly regions. This unique environment supports diverse marine life and vegetation. This map can assist in sustainable land management decisions, such as reforestation in areas with low GPP and conservation of regions with high GPP. It is also relevant to addressing issues related to Sustainable Development Goal 15: Life on Land.
