Mangroves are amongst the most productive marine ecosystems on Earth. At the land-sea interface, these forests provide food, breeding grounds and nursery sites for a variety of terrestrial and marine organisms, including many commercial species and juvenile reef fish. They also sequester up to four times more carbon than rainforests per hectare in their carbon-rich soils, and are the first line of protection for coastal communities against storm surges, flooding, and hurricanes. Yet, these habitats are regressing at an alarming rate: 20 to 35% have already been lost since the 1980s, mainly due to sea level rise and human coastal activities (urban development, aquaculture, mining, agriculture and overexploitation of timber, fish, crustaceans and shellfish). Guatemala is no exception in this context, and the global pandemic there has rendered coastal communities even more vulnerable. The Mangrove beekeeping project aims to increase their resilience in the medium and long term, while contributing to the protection of mangrove ecosystems. With a technical training program targeting women in priority, the project will provide a sustainable alternative livelihood to the Barra Sarstún community through the production of honey. Long-term mangrove conservation will be advocated through an educational campaign to raise awareness on their ecological importance and many benefits for human populations.
