case studies of successful governance models could be referred to by others in order to improve the management of the sector. This is the initial step toward compiling stories of aquaculture successes, and the editorial team is to be congratulated for its great efforts. In approaching this difficult assignment, the team benefited from the leadership of the Network of Aquaculture Centres for Asia and the Pacific (NACA), and the support of the World Fisheries Trust (WFT) as well as the Institute for International Sustainable Development (IISD) of Canada. We hope that the team will continue its endeavor in producing other aquaculture success stories, also from other regions of the world. Rome, Italy Jiansan Jia Pr eface We are moving into a turbulent and an uncertain era, particularly in respect of the future food needs. Given the push to sustainability, the rise in food prices, and the impending concerns around climate change and related complexity on providing the food needs for an increasing global population, it is time to address coping strategies. It is in this context that the issue on where will aquaculture development move in the future is taken up.

Sena S. De Silva is Director General of the Network of Aquaculture Centres in Asia-Pacific and Honorary Professor of Aquaculture and Fisheries Biology at the School Life and Environmental Sciences, Deakin University, Victoria, Australia.

F. Brian Davy is Senior Fellow at the International Institute for Sustainable Development in Canada and has over 35 years of experience in the field of aquatic resources.
