Lima-Callao Metropolitan Area, capital of Peru, is facing recurrent climate disasters providing lessons on water-related climate-proof governance reconfiguration. The first lesson is that when disasters affect poor and rich populations, dominant actors prioritise the integral city's resilience and development and coordinate and collaborate within a concertation framework across institutional levels and geographical scales , even having different ideas, discourses, and power, recognising that no single actor has enough power. Second, water-related climate-change scenarios require comprehensive, transverse, multi-sectoral, multi- scalar, multiple types of actor knowledge   and transparent information to manage the tensions and even conflicts when some knowledge is not shared or restricted, particularly when lower risk perception and higher risk tolerance are present. Finally, a concertative  strategy to localise climate-changed-related action shows quicker, more effective and more transparent results (medium confidence, robust evidence,
