Available here are the technical report and calculation sheet for a study commissioned by the South Atlantic Environmental Research Institute (SAERI) to assess water security options for St Helena. The findings contribute evidence to a programme of natural capital assessment (NCA) being implemented by JNCC and conducted by the South Atlantic Environmental Research Institute (SAERI) in the UK South Atlantic Overseas Territories. Funded by the Foreign and Commonwealth Office (FCO) managed Conflict, Stability and Security Fund (CSSF), the work sits under its Environmental Resilience programme which includes objectives to integrate natural capital considerations into economic and social development planning.

The report and calculation sheet contain cost-benefit analysis for different water security options on St Helena. These include limited new reservoir storage, a reservoir development at Fisher's Valley, desalination, and a mix of new storage and mist collection through cloud forest restoration, using discount rates of 4%, 7% and 10%.
