"Hovering low over the ground and shooting mangrove seeds into the water, drones may become a common sight in Myanmar by the end of the year. It's part of a reforestation project that aims to restore a natural ecosystem that is beneficial to wildlife, the environment and the local population. In the Irrawaddy Delta in the south of Myanmar, mangrove forests have been significantly depleted - often cut down so that people can use the area to plant rice, farm for prawns and collect palm oil. But mangroves have an important role to play in the ecosystem of the delta. As well as filtering the water, they also provide safe areas for fish and other marine life to live and grow, and capture large amounts of carbon from the atmosphere. And they protect coastal communities from flooding too, by naturally stabilising shorelines. It's thought that the cyclone that hit Myanmar in 2008 would have caused far less damage and loss of life if the Delta hadn't lost half of its mangrove area. People are aware that reforestation is needed, and moves have already been made to begin the process. Inhabitants of the Delta have so far planted 2.7 million mangrove trees by hand - an elaborate and time-consuming process..."
