Climate change has become the day-to-day struggle for this nation - an island nation that faces serious sea-level rise implications should the problem remain uncurbed. The impacts seen are related to rising temperature, sea-level rise (coastal erosion), and changes in rainfall (flooding). To reduce the vulnerability of the population of two regions next to its capital (Victoria), the Ministry of Environment and Energy of Seychelles initiated in 2012 a project aiming at improving the quality of life for the people of Seychelles and restore coastal zones as well as the ecological habitat related to them through nature-based solutions. The project will reduce these vulnerabilities by spearheading ecosystem-based adaptation as climate change risk management—restoring ecosystem functionality, and enhancing ecosystem resilience and sustainable watershed and coastal processes, in order to secure critical water provisioning and flood attenuation.

Coastal landscape management or protection, Ecological restoration of ecosystems, Protection of natural ecosystems, Knowledge creation and awareness raising, Improved governance of green or blue areas
Project objectives
Seychelles islands are an archipelago made up of about 115 islands with a total landmass area of 455 square kilometres. The estuarine and coastal ecosystems which include marshes, wetlands, mangroves, coral reefs, sandy beaches and seagrasses are some of the most threatened natural ecosystems in Seychelles due to rising sea levels, temperatures and changes in the rainfall pattern.
The intervention focuses on 2 of the most populated islands, Mahe (with the capital Victoria) and Praslin. The intervention addresses these issues by aiming at:
1. To reduce the vulnerability of the people of Mahe (the island where Victoria, the capital, is located, at a 2 km distance) and Praslin to water scarcity, and of the built environment to recurring flooding.
2. To restore the ecosystem functionality of degraded catchment areas and eroded coasts (reforestation and removal of invasive alien species and re-colonize with native plants).
3. To create wetlands, clear water bodies and rehabilitate coastal wetlands, enabling improved water flow and retention capacity, and aiding the recovery of coral reef habitat.
4. To create awareness regarding the climate change impacts and train local communities and volunteers in managing climate risk situations. (promoting local stewardship of watersheds) (2,3,4)
5. Protecting endemic tree species such as: Coco de Mer, Lodoicea maldivica, (Millionaire’s salad (Deckenia nobilis), Thief palm (Phoenicophoricum borsigianum); Seychelles stilt palm (Vershaffeltia splendid) Latanier millepatter (Nephrosperma vanhoutteanum) and Latanier palm (Rosheria melanochaetes)). - 70 endemic species were considered for ecosystem rehabilitation (2).
6. Stabilising and reforesting fifty hectares of bare ground and bush vegetation in the watersheds, concentrating on the most degraded areas (bare soils – 10 ha)
Implementation activities
The intervention was launched in 2014. Over a period of 5 years, the implementation activities consisted of building gabion rock barrages over 7 locations to create freshwater reserves using an approach that emphasises a natural approach to advanced engineering (2018). (6) In the same year, 2018 a tree-planting campaign aimed at rehabilitating watersheds and catchment areas by planting 4,000 trees native to Seychelles. (5) In 2019 a new climate change curriculum guide for teachers of primary five to secondary five classes which takes into account the situation for Seychelles was introduced in schools. (7)
Climate-focused activities
Climate change adaptation:
- Implement solutions to capture/store water to increase its availability and prevent shortages from droughts
- Protect coastal and freshwater ecosystems to prevent coastal erosion and pollution
- Restore wetlands and/or coastal ecosystems to dissipate the effects of flooding and/or storms
Biodiversity conservation or restoration-focused activities
Biodiversity conservation:
- Protect and enhance urban habitats
- Preserve and strengthen existing habitats and ecosystems
- Protect species
- Undertake specific measures to protect species
- Undertake specific measures to protect native species
- Undertake specific measures to protect valued species
- Control and clean invasive alien species
- Means for conservation governance
- Biodiversity offsets
- Raise public awareness
- Public engagement
Main beneficiaries

Yes
(The intervention was mainly based on 2 specific environmental documents:

2. The Water Development Plan 2008-2030 that include a recommended initiative for integrated river basin management, utilizing the current but dormant Rivers Committee as a focus for policy discussions. (2))
