This Medium-Term Plan (MTP) sets out the WorldFish Center response for harnessing fisheries and aquaculture to help address the global issue of food shortage and poverty by addressing two key development challenges: i) expanding sustainable aquaculture, and ii) ensuring productive and resilient small-scale fisheries. The MTP is developed around six major areas: 1. Global drivers of change 2. Markets and trade 3. Multi-level and multi sectoral governance 4. Improving sustainable aquaculture technologies 5. Aquaculture and the environment 6. Resilience in practice for small-scale fisheries.
