Project description

  • Several macro waste accumulation monitoring plots (over 2.5 cm) have been set up along the river deltas and Mozambican coast and are monitored by local observers.
  • These plots are also used to raise awareness among different groups (schoolchildren, tourists, members of the community) of pollution in Mozambique and to encourage reflection on waste life cycles and their spatial distribution (source, significant climate events). 
  • A protocol for estimating the amount of waste using drones is being tested.

The project is part of the WIODER network activities (www.widoder.org) on Indian Ocean deltas.
