This case study presents a detailed description of how community-based environmental education can be used to increase environment awareness and knowledge among migrant children and youth. Data was collected primarily from interviews and learning activities with 454 participants aged 11 to 19 years. The results show that children and youth are aware of environmental problems in their local communities. Environmental problems identified include open defecation, pollution, poor waste management and the use of unsustainable fishing methods. They are also capable of recommending solutions to some of these problems. Solutions recommended include planting more trees, providing waste bins in schools and public places, arresting and prosecuting people who practise open defecation, and public education on the need to stop practices that degrade the environment. The most popular tools recommended for educating children and youth on proper environmental practices and behaviour were dramas and plays. Children and youth thus prefer methods of teaching and communication that are audio-visual, encourage interaction and that keep participants actively involved in the process.
