Citizen Voices for Change: Congo Basin forest monitoring project (CV4C)


This project is financed by the European Union and the UK Department for International Development.

Through a partnership with Visioterra and Tropenbos, the CV4C project is developing this innovative radar-based satellite tool to monitor illegal logging and other forms of forest cover change.

The video below gives a full overview of FLEGT Watch and its mobile app.

How does it work?

This system overcomes the problem of cloud cover through the use of radar based satellite images enabling users to detect changes using the latest satellite maps and information on land use, forest cover, fires, and hydrology. FLEGT Watch, using synthetic-aperture radar will disseminate visual and geo-referenced alerts that can be received on tablets and smartphones, enabling forest watch communities to enhance their performance.

What can it do?

  • Systematically analyze data from Sentinel-1 and Sentinel-2 satellites
  • calculate bio-geophysical indices related to the forest (biomass, leaves, vegetation, humidity …),
  • automatically detect the changes of values ​​of these parameters in the satellite image just acquired,
  • send notifications of change (s) or alarms to observers in their areas of interest,
  • embed satellite data, maps and images in a field application and / or on smartphones,
  • allow to find evidence (photos, measurements, comments …) in-situ and to share them in the network of observers and beyond,
  • provide dashboards of observed changes and their monitoring by observers,
  • publish reports on all observations or a particular observation,
