The third international Amsterdam International Water Week (AIWW) conference and ‘Aquatech’ trade show held at the RAI conference centre Amsterdam 2-6 Nov 15 attracted over 19,000 water technology professionals, academics, development professionals, regulators and policy makers. This year’s central theme was ‘Integrated Solutions for a Circular Economy and Resilient Cities’ with some 80 conference sessions under three linked ‘platforms’ over two days. On behalf of the Sustainable Fisheries Partnership, Dr Francis Murray gave a presentation titled ‘Zonal Aquaculture Improvement Projects with Aquaculture Industries in China, Indonesia and Vietnam’ in a session on ‘Water Efficient Food Production’. The talk highlighted environmental sustainability limitations of individual farm-based certification systems and the corresponding need for coordinated wider industry and regulatory agency support to enable producer organisations to manage water quality and disease risk in shared water resources. SFP pilot ‘Aquaculture Improvement Project (AIP)’ case studies in SE Asia were used to demonstrate progress and challenges in implementation of such zonal or ‘area based management (ABM)’ schemes in water basins where production remains dominated by large numbers of small-scale farms.
