Samenvatting

In coastal and low-lying vulnerable delta cities, such as the Rotterdam Metropolitan region and Metropolitan Manila, there has been an increase in vulnerability of urban flooding and water quality problems. New approaches address the current and future effects of climate change and increase urban quality, reduce vulnerability and increase water quality. New arrangements for international cooperation are set up in order to address these problems in the project ‘IWASTO’ (‘to correct and to prevent’) where several organisations from the Philippines and The Netherlands join forces to rehabilitate rivers and introduce new innovations for water quality monitoring and waste collection using the ‘Research Design and Manufacaturing (RDM)’ approach. One of the concrete results from this RDM approach in 2016 is the development and implementation of the ‘Longganisa’, a waste collection tool that was designed by a Dutch-Philippine team. In addition, the waterquality was measured and mapped with innovating methods using apps in order to locate and prioritize highly polluted areas. In the near future measures will be implemented to rehabilitate the rivers in Manila and a knowledge exchange forum will be set up to share the best management practices on international scale in countries as Indonesia, India and China.
