When it rains in Nairobi’s informal settlements, the story isn’t just about floods, it’s about resilience being built one idea at a time. In neighborhoods like Dandora, Korogocho and Kamukunji, where broken drainage lines and unpredictable floods are part of daily life, people aren’t waiting for help. They’re experimenting. They’re adapting. They’re creating low-cost systems that keep their homes dry and their streets passable long before experts arrive. At the Cool Waters Climate Change Academy, these community stories are being turned into case studies, living lessons that show how climate adaptation in Nairobi doesn’t start with million-dollar plans but with ordinary people testing what works. One group designed raised gardens that double as drainage buffers. Another mapped out local flood points using chalk and phone cameras. Others realized that tree planting could do more than provide shade, it slowed runoff water from rain and stabilized paths that used to erode with every downpour. These are not isolated acts of survival. They are prototypes of climate adaptation Nairobi can learn from. And they’re proof that community resilience in Kenya is more than a buzzword, it’s a movement born from necessity. “We don’t have the luxury of waiting for experts,” said one trainee. “If we don’t adapt, we lose our homes.” Every session of the Cool Waters Climate Change Academy reinforces this truth: adaptation is not a concept; it’s a daily act. By blending technical knowledge with local insight, PSN is helping communities translate lived experience into models that can be scaled and replicated across the city. The next time it floods in Nairobi, the real question isn’t how much rain fell, it’s how much local wisdom rises to meet it. Watch how these local adaptation ideas evolve in real time through PSN’s platforms as the Academy continues to document new solutions from Nairobi’s frontline communities: Instagram (https://www.instagram.com/publicspacenetwork/), TikTok (https://www.tiktok.com/@publicspacenetwork0), and LinkedIn (https://www.linkedin.com/company/public-space-network/?viewAsMember=true).
