How does a community adapt to challenging times? A tiny home built to withstand floods. Ancient floating gardens bringing a canal back to life. Giant fishing nets and the people working to protect a threatened tradition. Across Bangladesh, Mexico and Thailand, communities are finding practical ways to protect their homes, food systems, waterways and livelihoods. In Bangladesh, families are building simple, flood-resistant homes designed to keep people and food supplies safe during intense monsoon seasons. In Mexico City, farmers in Xochimilco are restoring ancient floating gardens to support cleaner waterways, local food production and habitat for the endangered axolotl. In Thailand, fishers and researchers are mapping their lake and creating fish shelters as they work to protect a distinctive giant lift-net fishing tradition affected by pollution.These are the stories in Hands On: Stories That Build Change, a Mongabay video series exploring community-led environmental action in a changing world.
