The Problem

The most affected by plastic pollution and over fishing are the poorest communities who often live within biodiversity hotspots. Discarded fish nets are a major source of pollution and a hazard to marine life while overfishing causes loss of an entire ecosystem. How do we create a sustainable solution that empowers fishermen and allows them to overcome poverty while preserving the environment?

The Solution

Net-Works has launched programmes in 36 communities in the Philippines and Cameroon and is planning to expand.

  • Establishing a supply chain for discarded fishing nets which are recycled into nylon yarn and for seaweed extracts to provide communities with an added income

  • Community banks are put in place enabling local communities to access financial services.

  • Creating more marine protected areas to replenish fish stock
