A Rocha is driven by biblical faith and commitment to science. Dr Robert Sluka, Lead Marine Scientist, recently spoke (download text) at the United Nations Ocean Conference about the work of A Rocha and the integration of Christian faith and marine conservation. He shares the goals and ethos behind the marine programme in this short video.
Oceans and Communities
Transformed by Holistic Conservation
The model we are using to accomplish this transformation is to let both science and theology drive our conservation, education and advocacy efforts. This is all based in a strong connection to and cooperation with local communities.
We determine the range of locally important species, habitats and ecological threats to the focal marine environment. As a Christian organisation, we rigorously study our faith in order to determine principles which guide our lifestyles, ethics, and relative importance of particular issues.
We are committed to working towards the accomplishment of all SDGs. In order to meet Sustainable Development Goal 14 on oceans, faith communities need to be effectively engaged and equipped. Our projects intentionally focus on SDG 14 and highlight interactions with other SDGs where they overlap.
Biodiversity and Beauty
Project: Watamu Marine National Park, Kenya
Our work has focused on documenting marine biodiversity and in collaboration with Oxford University, the first habitat map for the marine park. We have begun a project focused on the rockpool habitats which house endemic biodiversity rare in the Western Indian Ocean, such as the crisp pillow coral seen below.
Our biodiversity work has revealed a number of IUCN Redlisted species, particularly sharks, rays and guitarfish. This has been published in Atoll Research Bulletin.
Project: Lee Abbey, UK
We utilized scientific surveys of Lee Bay to determine marine biodiversity and selected 10 species which were most common and also easily identifiable by non-scientists. A Rocha UK marine intern and Marine Team member Hannah Hereward produced a Top Ten brochure which visitors can use to search the beach for these species. These brochures and signage in Lee Abbey house (and in the future at the beach) have links pointing to online resources about the science of the bay and also Christian devotional writing which could help visitors to interact with these species in light of their faith.
The Karioi project provides an educational program based around a range of habitats from Maunga ki te Moanaincluding; coastal forest, freshwater streams, marine rocky shore and inter-tidal marine ecosystems. The project is actively working together towards an integrated pest control program to re-establish Karioi as a seabird mountain. Currently we are implementing predator control to protect the remnant population of Oi that still burrow around the shorelines of Karioi.
An Ocean of (Plastic) Hope
A Rocha’s research and conservation on marine plastics has focused on helping people to understand the extent of the problem globally and providing resources to help them get involved. We have developed a beach clean up guide so you can organise your own event and The Microplastics Toolbox which has loads of resources to help you learn, act and conduct citizen-science research.
Project: Global plastic cleanup
A Rocha national organisations are participating in the 2018 International Coastal Cleanup including Australia, New Zealand, Kenya, South Africa, Netherlands, Portugal, UK, and USA.
Microplastics are ubitquitous on coasts globally. We have developed The Microplastics Toolbox to help national organisations to monitor microplastics. Currently A Rocha Portugal is monitoring microplastics on the Algarve coast. Nurdle hunts are being used to examine these microplastics in Australia, Portugal, the UK, and USA.
Food Security, Human Health and Wellbeing
Project: Watamu Marine National Park, Kenya
Our field study centre in Watamu is located on the shore of a marine national park where we partner with Kenya Wildlife Service to provide information to help with the management of that marine protected area. Fishermen benefit from the the park through larger fish moving out of the park and being caught, increased reproduction, and eco-tourism job opportunities.
A Rocha Ghana in collaboration with the Wildlife Division of the Forestry Commission has undertaken several activities as part of efforts to restore the ecological integrity of the Ramsar site as well as improve the livelihood of communities utilizing the resources at the Muni-Pomadze Ramsar Site.
Project: Tana River Delta, Kenya
The Tana River Delta is one of Kenya’s largest and most important freshwater wetland systems both rich in wildlife and with a significant local community of cattle herders and others dependent on it and who have done so for centuries. A Rocha Kenya works with other partners to implement conservation initiatives to protect the delta and provide sustainable alternatives for local communities.
Project: Ocean theology
We are developing resources to help Christians connect their faith to their experiences of the ocean. This includes reflecting on ocean threats such as overfishing, climate change, and pollution. Some of the resources available can be found at our church resources site.
