Algae cultivations in Kenya- a sustainable solution? : An assessment and investigation over deepwater cultivation in Shimoni, Southern Kenya

Abstract: With a strong demand for aquatic products, seaweed is a promising application in a wide range of areas, such as food, medicine and energy. Kenya is seen as a country with great potential of expanding its seaweed industry, and by inspiration from the widespread production of algaes at Zanzibar, improvements and adaptations can be made to fit Kenya. One of the places with proper environmental conditions is Shimoni, situated in the south coast of Kenya, and the purpose of this report is to assist on the expansion of seaweed farming in Shimoni, by assessing the possibilities of deep-water cultivations at site, and mediate strengths, weaknesses, opportunities and threats with the technique. In addition, another purpose is also to map out important stakeholders for starting up and expanding the system. The methods SWOT-analysis and stakeholder mapping have been carried out by literature studies and interviews with local scientists. Results have shown that deep-water techniques are less demanding on the environment than cultivations in the intertidal area and may support the local environment if proper conditions are provided for. Seaweed cultivations have large potential as an additional livelihood opportunity in coastal communities, given that adjustments to changes in market prices and environmental conditions can be met. However, deep water methods require larger initial costs than the ones carried out in the intertidal, hence political and technical support may be crucial for launching the system. These processes may be implemented iteratively as business opportunities arise. In conclusion, field research covering non-expected local aspects is further recommended.
