Global Mangrove Monitoring

Activity ID: 96

Overview

The overall goal of this project is to:

  1. update the global mangrove database of 2000 to 2015;
  2. back-cast it to 1990 and 1980; and
  3. perform change analysis to identify rates, patterns, causes and consequences (e.g., carbon stock change) of mangrove forest cover change of the world.

In 2011, USGS prepared the most comprehensive, accurate, and consistent mangrove database of the world using Landsat 30 m spatial resolution satellite data for the year 2000. The data is freely available from a number of organizations including Google, the World Resource Institute’s Global Forest Watch, UNEP-World Conservation Monitoring Centre, the Center for International Earth Science Information Network (CIESIN), and the United State Geological Survey (USGS). The data has been cited more than 500 times since its publication in 2011. The data is being used from local scales to global scales because the data is globally consistent and locally relevant. Although, extremely useful, the 2000 data is becoming increasingly dated.

Activities for the period

Building on the global mangrove database for the year 2015, the United States proposes back-casting for the year 1990 and 1980, and perform change analyses to identify the rates, patterns, causes and consequences of the changes. Additionally, we will monitor the mangrove on an annual basis.

Future Plans

The United States will monitor both natural and anthropogenic changes. Mangrove could serve as an indicator of climate change and we will monitor both landward and seaward expansion. The mangrove and change database will be extremely useful for a number of applications including identification of priority mangrove conservation areas, identification of mangrove restoration areas, and enumeration of blue carbon sequestration potential. 

Resources

Funding from USGS is now secured for three years to perform this task. The project will be implemented by Environmental Protection Agency (EPA) in coordination with USGS and UNEP.
