In the heart of the Amazon Basin, where the borders and cultures of Peru, Colombia and Brazil converge, a tiny, shape-shifting island has become the unlikely setting for a diplomatic tug of war.
“If God wanted, the river would change and even Santa Rosa could disappear,” said Gladys Hari Leiva, a hotel owner who has lived on the island for 21 years.
The island’s mercurial geography makes it a difficult place to settle; families adapt season by season, walking across sandbanks in the dry months, then paddling canoes through flooded streets when the rains come.
Santa Rosa’s fragility has not stopped Peru and Colombia fighting over it. In fact, its shifting shoreline has made matters worse.
Yet despite these limitations, the island is coveted by the countries around it. Peru and Colombia have argued over who the island belongs to for decades. As the Amazon River moves, so too does the international boundary between the two countries.
The main channel of the Amazon River constantly erodes existing land and deposits new earth. Each year the river carries roughly 1.2 billion tons of sediment from the Andes toward the Atlantic, reshaping its banks and islands as it flows. During high-water months, water spills over and settles across the floodplain, leaving behind up to 12 inches of fresh soil annually.
Residents who have lived in the Basin for a long time are used to the seasonal ebb and flow of the water and land, but it’s becoming less predictable.

Across the industry, innovation in eco‑design for buildings and renewable building materials demonstrates measurable progress in reducing embodied carbon and improving whole life carbon performance. West Fraser’s CaberShield ECO flooring system reflects how low embodied carbon materials can meet conventional durability standards while supporting environmental sustainability in construction. The move toward circular economy principles and life cycle thinking in construction is reinforced by advanced digital modelling for whole life carbon assessment, generating data that informs retrofit strategies and life cycle cost optimisation.
Professional engagement is intensifying as institutions such as the RICS advocate collaboration to deliver net zero carbon buildings and end‑of‑life reuse in construction. Despite softening market conditions and reduced housing registrations, developers are being urged to adopt sustainable building practices that ensure long‑term building lifecycle performance and minimise the carbon footprint of construction.
Sustained funding, enforcement, and material innovation are essential to decarbonising the built environment. Achieving net zero whole life carbon will depend on integrating sustainable material specification, environmental product declarations (EPDs), and circular construction strategies into every phase of design and delivery. Britain’s green construction agenda will only succeed if sustainable building design evolves from aspiration to standard practice, ensuring that each low carbon building contributes to a resilient, energy‑efficient, and resource‑efficient future.
