Today, much of the precipitation in the Seychelles falls in sharp bursts, creating heavy flooding in the wet season, while imposing extended period of drought during the dry season. Climate Change projections in the Seychelles predict more intense rainfalls and drought periods. As the country does not have a large water storage capacity, and the topography of the islands constrains such infrastructure, water supplies are heavily dependent on rainfall. Furthermore, the coastal zone is vulnerable to flooding, because of rising sea surface levels and increased storm surges from cyclonic activity in the Western Indian Ocean. Because of these reasons, water management has become a priority in the Seychelles with a particular focus on water policy and watershed management. The Seychelles seek to integrate environmental considerations in cross-sectoral policies and to streamline national and international commitments related to climate change adaptation.
Following the recommendation of a geotechnical and financial feasibility study of wetland creation that was prepared during the implementation of an Adaptation Fund Programme, the CTCN will support with this Fast Technical Assistance to formulate a pre-concept proposal to the Innovation Facility of the Adaptation Fund (AF). This pre-concept note will support to confirm the interest of the AF in financing the detailed design phase (and potentially the implementation) of the innovative water retention structure in “La Drisse” depression, in the Mare-aux-Cochons watershed in Seychelles. The aim is to sustainably manage the watershed to secure freshwater resources that are essential for climate change resilience on Mahé.
The expected impact of this Fast Technical Assistance is to leverage financing to enhance the hydrological management of the Seychelles and address two major water supply challenges. On the one hand, address the need to transfer water towards the zones of treatment and consumption (from the West to the East), and on the other hand, to increase storage capacity in the Seychelles. This Fast Technical Assistance also contributes to the NDC objectives of the Seychelles to lower lasting adaptation impact in terms of energy and water security, as well as, improving the resilience across its communities.
