Check out the efforts of some like-minded (global) citizens. Their project is called Hariyo Chowk, which means "Green Square" or "Green Commons" in Nepali. The group started transforming a small plot of land in Kathmandu into a community space last spring and have already built a bamboo structure for vertical gardening, a mudbrick oven for cooking, a sunken pit for fires, and a stage for gatherings and film screenings (bicycle powered too!). They've also started planting native and edible plants, and hosting work days and workshops. Impressive!
