Description

  • This research provides an overview of mangrove restoration in Bangladesh.
  • Scientists have estimates that of the three coastal ecosystems (coral reefs, sea-grass beds, and mangroves) that mangroves are the most feasible habitat to restore.
  • However, due to ecological and social factors many mangrove plantations fail. In the Nijhum Dwip Island of Bangladesh, the two species most often used (85%) in plantations are the native species Sonneratia apetala and Avicennia officinalis.
  • Occassionally other species are used such as Bruguiera gymnorhiza, Ceriops decandra, Excoecaria agallocha, and Nypa fruticans.
  • Repeated planting has to occur for the first 3 years of establishment, however, once established they often face encroachment and illegal felling.
  • For this research, the authors conducted 110 interviews to evaluate socio-economic conditions, human connection to mangroves, and the identification of species diversity in mangrove areas.
  • Respondents identified 38 plant species and 64 animal species that depend on the mangroves.
  • Respondents expressed a conflict between humans and the incursions of wildlife onto their farms and households.
  • Approximately one-fourth of the respondents felt dependent on the mangrove ecosystem with benefits including: protection against natural disasters, soil retention, and the provision of resources.
  • Many respondents expressed that the conversion of the mangrove lands into farmland, timber plantations, settlements, and aquaculture would be a more profitable way of using the land.
  • Over 80% of respondents felt that the mangrove ecosystem is actively being degraded by encroachment, illegal logging, and other factors.
  • The authors suggest that there are shifts in opinions about mangroves.
  • They recommend adaptive co-management to allow stakeholders to participate in the management of mangroves.
