Mozambique has committed to restoring 5,000 hectares of mangroves as part of its Mangrove Management Strategy (2020 – 2022). There is also a growing national research initiative that’s been looking at the role of mangroves in protecting against the negative impacts of cyclones.

Multiple cyclone impacts have been documented:

  • Cyclone Eline and 2000 floods destroyed 60% of the mangroves in Limpopo’s estuary
  • Multiple cyclones have impacted 47% of the Save river estuary
  • More recently, Cyclone Idai (2019) battered and flooded the city of Beira.

A key recent finding from this research is that the active unblocking of creeks reinstates tidal inundation, which has led to a three-fold increase in restoration success.
