Global kelp restoration through restorative sea urchin aquaculture. Urchinomics is a sustainable sea urchin harvesting venture that aims to turn an environmental challenge into a commercial, ecological and social opportunity. Overfishing of predatory species, climate change and pollution has allowed sea urchins to explode in population. Uncontrolled quantities of sea urchins overgraze kelp forests and seagrass meadows, turning once pristine and vibrant marine ecosystems into lifeless, barren deserts, or "Urchin barrens". Urchinomics specifically targets these ecologically destructive urchins and turns them into luxury gourmet seafood product, thereby helping kelp forests recover to their original healthy ecosystem, in the process encouraging fish and marine biodiversity, sequestration of CO2 and creating meaningful full-time jobs in rural communities.

The World Seagrass Association is a global network of scientists and coastal managers committed to research, protection and management of the world’s seagrasses. Members come from many countries and include leading scientists in marine and seagrass biology. The association supports training and information exchange and raises global awareness of seagrass science and environmental management issues.

WIF works with local communities to reforest and conserve mangrove forests in Myanmar and across the Bay of Bengal. Their mission is to plant one billion mangrove trees mitigating 500 million tonnes CO2. In addition, to improve and empower coastal communities to a better life while promoting bio-diversity and protecting endangered species, Worldview’s research project in Myanmar in cooperation with Ministry of Environmental Conservation and Forestry, Pathein University and Myek University, aims at a national plan for restoration of mangrove forests in all coastal areas of the country. The project is funded by Letten Foundation, Norway. Worldview is also following up mangrove projects in Gambia and other countries, as part of its global efforts in adaptation to climate change

Blue Forests began to work in 2000 in Indonesia. Originally, it was named Yayasan Akar Rumput Laut, then it changed to Mangrove Action Project – Indonesia prior to the establishment of Yayasan Hutan Biru (Blue Forests) in 2011.
