When we talk about nature-based solutions (NbS)—that is protecting, managing, restoring or creating ecosystems for the benefit of the people and biodiversity—we almost always think of wilderness or rural areas. We think of famous forests like the Sundarbans, large wetlands like Hakaluki Haor or Chalan Beel, or impressive plantations of the Bangladesh Forest Department, NGOs, and villagers throughout the country. But what about our cities and towns? Can we have any NbS for them? Of course we can.
