Island ecosystems are fragile. Opening up an island to tourist travel could extract a heavy toll on the environment.
One of Banwa’s key projects for Mararison is providing fresh, clean drinking water for the island’s residents and visitors. Banwa plans to set up a water desalination plant on the island to provide clean water without further taxing the island’s freshwater resources.
At present, the islanders still need to purchase expensive fresh water from the mainland for their needs. Transport to the island is labor-intensive, costly yet necessary particularly during the summer months when supply from the rainwater catchment runs low.
