The objective of this workshop led by Paolo Paron of IHE-Delft and organised in the framework of the GDRI-Sud Deltas and the DiDEM program is to train the WIODER network's teams in using remote sensing and GIS tools and to define common protocols for comparing 4 deltas: the Tana in Kenya, the Betsiboka in Madagascar, the Incomati in Mozambique and the Rufiji in Tanzania.

The first results of the comparison are very enlightening on the vulnerabilities faced by the Indian Ocean deltas: deforestation in the catchment area, reduction of flooding areas, landscape fragmentation.
