A Rocha is driven by biblical faith and commitment to science. In order to meet Sustainable Development Goal 14 (SDG 14) on oceans, faith communities need to be effectively engaged and equipped. Combining science and theology over the long-term more effectively deals with the complexity of our planet’s situation, balances hope and despair, and leads to successful marine conservation. Our recent newsletter highlights our marine conservation projects. 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.
Goal and Strategy
The goal of A Rocha’s Marine and Coastal Conservation Programme is to participate in the transformation of the ocean and the people who use it so that the ocean becomes a place of abundance and teeming and is fruitfully and sustainably used by people.
The model we are using to do this is to let both science and theology drive our conservation, education and advocacy efforts. Utilising our own and the latest published science
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.
Out of the synergy of these two maps of reality flow our conservation, education and advocacy efforts. The attempt is towards holistic projects which take into account a scientific understanding of marine conservation as well as our own and the local community’s worldviews such that projects combine attention to biodiversity, livelihoods, and spirituality.
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.
Our work has focused on documenting marine biodiversity, coral reef resilience to climate change, and impacts of tourism on coral reefs. We developed, in collaboration with Oxford University, the first habitat map for the marine park and 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 long running education programs have now incorporated marine conservation activities into their work with local school and we have also developed projects training local guides to increase livelihood opportunities.
We have addressed faith issues through a themed programme titled The Hidden Things of God in the Ocean [free download]. This programme engages people with the beauty of rockpool biodiversity, hidden from sight by the tides, revealed at low tide. By combining Biblical metaphors concerning revealing hidden things and healing we have explored the role of faith in marine research and conservation. See the references for links to downloadable resources.
Science has thus set the stage for opportunities with faith motivating our work and theological reflection on its purpose and all this working itself out within a Christian community. This has then led to experiential educational work, advocacy for habitats and species not currently focused on in local conservation efforts, and conservation activities which focus on both people and place, particularly incorporating livelihoods development among those utilising the ocean for food and income.
An Ocean of Plastic
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.
Educational work has already started at a number of Christian conferences and events focusing on engaging Christians with the scientific issue of microplastic pollution and linking this to teaching from the Christian faith on our responsibility for taking care of the ocean. Additionally, we have completed educational projects in collaboration with the Anglican Church of Monaco and as part of the Monacology event, residential courses at A Rocha France’s Les Tourades field study centre, and at Cruzinha, A Rocha Portugal’s field study centre and birth place of the A Rocha Movement.
A microplastics factsheet was developed and translated into French, Spanish and Portuguese for use across our 20 national organizations – download it at the bottom of the Microplastics project page.
Microplastic research is beginning in Florida, USA, the photo of a nurdle taken at the National Seashore near Cape Canaveral
We have also used social media to alert our constituents globally to the pressing issue of plastics in the ocean such as short videos like below and posts linking to other work.
Lee Abbey – United Kingdom
A Rocha works in partnership with the University of Plymouth and the Marine Biological Association to study the impacts of climate change on a coastal seaweed, particularly in relation to seaweed bleaching with increases in climate change induced heat waves alongside identifying the changes in limpet grazing across the seasons. Our study sites are located near one of our A Rocha UK Partners in Action, Lee Abbey, a Christian conference centre located in Devon.
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 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.
Additionally, on dates such as World Oceans Day, the community and visitors cleaned the beach of rubbish and plastic, finishing with a campfire which featured a devotional teaching on why what they just completed was an important Christian act. This solidifies in people’s minds that these acts are to be a part of their regular practice of faith – body, mind, heart, and soul engaged holistically.
Hannah Hereward giving a personal reflection on her studies to visitors to Lee Abbey
We are currently utilising the scientific data to identify potential species of conservation concern and potential advocacy topics. We also currently advocate generally for marine conservation among Christian churches through A Rocha UK’s Eco Church programme and through lectures.
