Clark Labs, in partnership with the Gordon and Betty Moore Foundation and in support of the Foundation’s Oceans and Seafood Markets Initiative, is mapping an inventory of pond aquaculture and coastal habitats around the world. Ten countries thus far have been mapped for landcover for the years 1999, 2014, and 2018. Along with landcover, for each country a change analysis is performed at the provincial or state level between all years mapped. All data are available for download through the links below. In addition to downloading the data you can explore the data using an interactive web map. The landcover maps for 2014 and 2018 are based on Landsat 8 imagery and the landcover maps for 1999 data are based on Landsat 5 imagery. Three main landcover categories are mapped: mangrove, coastal wetland, and pond aquaculture. When possible a distinction is made between fresh and brackish pond aquaculture. Additionally, the database includes a mapping of present-day vulnerability for further conversion to pond aquaculture and a mapping of the risk of landcover conversion to pond aquaculture by 2050. See the Reports section below for complete detail on the methodology. As more countries and dates become available they will be posted here.
Landcover and Change Analysis Data Download
All files are in raster format and distributed as compressed GeoTIFF files. Each zipped archive contains text files describing the spatial referencing system and the legend or data values. For information on the procedures used and accuracy/skill of the mapping, please see the Reports section below. The landcover maps are at a 15m resolution while the vulnerability and risk layers are at a 30m resolution. The data are copyright © 2021 by Clark Labs, Clark University.
