This project focuses on the impact of climate change on coastal areas and tropical islands near the equator, the most suitable for coconut growth. Sea level rise is endangering the very survival of coconuts as well as threatening people’s lives.

Tuvalu is arguably the first country on the line, as its highest altitude is less than 4m. Funafuti is its largest and more populated atoll, with coconut being the staple food and only export. The project intends to formulate coping strategies for areas threatened by sea level rise in the atoll, taking advantage of the economic benefits of coconut-derived products. The project proposes new sustainable ways to reclaim land, making use of coral reefs’ characteristics, encouraging the accumulation of sediments and slowing down erosion.

Challenging destructive traditional land reclamation, the design deploys mangrove and coconut as the main actors, using floating structures work as sediment accumulators, promoting the natural expansion of coastal land, sand fixation and protection. On the premise of protecting coral reefs, more usable land is created for coconut planting for subsistence and export while providing a unique coastal landscape.

The bamboo frame will decay over time, supporting the mangrove growth. Coconut shells will provide buoyancy and nutrition, helping the mangroves to settle, accumulating sediments to form new land around the floating island.

Mangrove Growth and Frame Degradation

The bamboo frame will decay over time, supporting the mangrove growth. Coconut shells will provide buoyancy and nutrition, helping the mangroves to settle, accumulating sediments to form new land around the floating island.

The small modules of the natural floating island are made of environmental protection materials, and the frame materials can be recycled or naturally decomposed during plant growth in the later stage, reducing ocean pollution.

Vegetation, landscape facilities and groynes will be gradually built with the advance of the coastline. Mangroves, coconut forests, beach grass slopes and other vegetation can provide protection for the newly formed beach and increase stability.

The Growth Process of Residential Floating Island: Plan

Vegetation, landscape facilities and groynes will be gradually built with the advance of the coastline. Mangroves, coconut forests, beach grass slopes and other vegetation can provide protection for the newly formed beach and increase stability.

Mangrove floating islands, coastal coconut forests and other tropical crops and landscape facilities will be constructed synchronously with the formation of the new beach.

The Growth Process of Residential Floating Island: Sections

Mangrove floating islands, coastal coconut forests and other tropical crops and landscape facilities will be constructed synchronously with the formation of the new beach.

After the sediment deposition is stabilised, the new coast will have mangroves, shrubs, coconut forests and other major vegetation. This figure includes technical and material analysis of key areas.
