In order to enable cities to adapt to climate change and climate-related weather extremes, urban planners and regional decision-makers need a local database for climate-resilient urban development. The project supported cities to use participative approaches, based on information and communication technologies, in order to strengthen their climate resilience. Innovative approaches to data collection and evaluation enabled city administrations and decision-makers to obtain the necessary information for developing and implementing local adaptation strategies. Findings from three pilot cities in India, Mexico and Peru with differing risk scenarios were introduced to the international discourse in cooperation with German and international partners.
