How long have you / your team been working on this Vision?

  • 1-3 years

Lead Applicant: In what city or town are you located?


Lead Applicant: In what country are you located?


Your Selected Place: what’s the name of the Place you’re developing a Vision for?

Gran Canaria

What country is your selected Place located in?


Describe your relationship to the place you’ve selected.

Was previously a Visiting Professor at the University of Las Palmas, and had always dreamt of setting up "CASA" - Center of African Studies on Aquaculture, where students from African countries could be trained on aquaculture technologies relevant to their own particular country.

Describe the People and Place: Provide information that would be helpful for an outsider who has never been there and may have no context about this Place to better understand the area.

Proximity to the African continent, climate & coastline, and experience of local institutions in aquaculture development

Challenges: Describe the current (2020) and the future (2050) challenges that your food system faces.

Challenge: Fish and seafood constitute a much needed affordable source of essential dietary nutrients for most African countries (usually constituting the major source of animal protein consumed). Notwithstanding the above, at present within most African countries the majority of fish and seafood is still supplied from wild capture fisheries, and the status of these wild fish stocks is under threat from over fishing and collapse. Moreover, the emerging aquaculture sector in Africa (Egypt, Nigeria, Uganda) has been largely restricted to the mass production of freshwater fish species (such as Tilapia and Catfish) dependent upon the use of compound feeds composed largely of imported feed ingredient sources.

Address the Challenges: Describe how your Vision will address the challenges described in the previous question.

The current project intends to increase aquaculture production in Africa by cultivating local species not dependent upon the use of external feed inputs but rather the use of the nutrients contained within the deep waters surrounding the African continent. This will be achieved by using wave-generated nutrient upwelling for the mass production of edible aquatic plants (green and red seaweeds), and filter-feeding shellfish (mussels, clams, oysters) and finfish (forage fish species such as sardines and anchovies). Since these culture systems do not currently exist in Africa, it is envisioned that the project feasibility be first demonstrated in the neighboring Canary Islands off the cost of Africa.

High Level Vision: With these challenges addressed, now provide a high level description of how the Place and the lives of its People will be different than they are now.

Increased aquatic food production and availability, and increased food security and nutritional wellbeing of coastal African countries using innovative wave-generated nutrient upwelling - Ocean Garden's.

Full Vision: How do you describe your Vision for a regenerative and nourishing food future for your Place and People for 2050?

Project feasibility and proof of concept will be developed within a five-year time period, with full economic analysis and development of sustainability criteria. Environment: aquatic food production, nutrient upwelling, wave energy, use of local native species, carbon dioxide sequestering; Diets: aquatic food production, improved food security, improved nutrition & wellbeing; Economics: use of local resources at little or no cost to the farmer or coastal community, economic feasibility assessment; Culture: dependence on local labor and fishing communities, use of locally preferred edible species; Technology: wave-generated nutrient upwelling, mass production methods for the production of native aquatic plants and filter-feeding marine forage fish and shellfish; Policy: increased use of local resources, increased employment opportunities, reduced dependence upon imports, increased food security and poverty alleviation;

Great project! born and raised in the Coastal area of Kenya; Mombasa, saw your post and am really interested to learn and have an input on aqua system through innovation, regards Archiebold
