The GCA +20 was successfully held as a hybrid event from 22-25 September, with physical participation at the venue in Shanghai, China, and international participation via video conference. A total of 1,728 people participated in the event, of which 500 were physically present in Shanghai. A key output from the GCA +20, the Shanghai Declaration is a call to action that highlights the principles and strategic pathways to maximise the contribution of sustainable aquaculture in achieving the Sustainable Development Goals, with a special focus on “Leaving no one behind”.

Over the last five decades, over 30 million people along Java’s north coast have experienced subsidence and subsequent soil erosion. In 2015, Building with Nature Indonesia (BwNI-Demak) started a coastal protection project in 10 communities of nine coastal villages of Demak regency. The protection measures introduced included the use of permeable structures (dams) that successfully capture sediment and support natural recovery of mangroves, and aquaculture field schools, to train small-scale farmers on good aquaculture practices such as low external inputs sustainable aquaculture, associated mangrove aquaculture and multi-trophic srhimp aquaculture.

Vietnam has a vast coastline which exposes it to typhoons and flooding. Farmers are at the frontlines of experiencing climate change as their livelihoods are intrinsically linked with the natural environment. Our study collected local knowledge of aquaculture farmers living in South Central Vietnam. The purpose of the interviews was to gather firsthand knowledge on current climate change impacts experienced by farmers, as well as which climate change threats they are most concerned about, and how they are adapting to these threats.

Climate variability and change are affecting hydro-meteorological cycles and altering aquatic ecosystems, driving shifts in physical and chemical processes, ecological communities and the distribution and abundance of species. These changes have implications for fisheries management, food security and the livelihoods of more than 600 million people worldwide. The FishAdapt conference was held in Bangkok from 8 to 10 August, 2016. It provided a forum to share practical experiences in understanding the vulnerabilities associated with climate change and ocean acidification and the development of risk management and adaptation strategies.

FAO and NACA have signed an agreement to convene a global conference on aquaculture in 2020. This will be the fourth conference in a series that began at the dawn of the industry in Kyoto, 1976. Aquaculture 2020 will be held late in the year in China. Arrangements, programme and partner details will be announced via the NACA website in due course.

Improvements to fish yield in small water bodies as well as to the incomes and nutritional status of rural communities have been demonstrated. in Laos, Sri Lanka and Vietnam but culture-based fisheries practices are not yet widespread, despite having significant potential in tropical climates. A project to introduce culture-based fisheries to Cambodia is described. Participating communities reported improved catch per unit effort, an increase in the number of people engaged in fishing and lower food costs.
