Book excerpt: The purpose of the United Nations challenge badges is to raise awareness, educate and, most of all, motivate young people to change their behavior and be active agents of change in their local communities. Challenge badges are appropriate for use with school classes and youth groups, and are endorsed by WAGGGS and WOSM. They include a wide range of activities and ideas that can easily be adapted by teachers or leaders. Additional badges are available or are being developed on a number of other topics, including: Agriculture, Biodiversity, Climate Change, Energy, Forests, Hunger, Nutrition, the Ocean and Soils. The Water Challenge Badge is designed to show the crucial role water plays for life on our planet as well as for human wellbeing. The badge looks at how our water supplies are affected by human pressures, considers solutions for how water can be used more efficiently and motivates young people to save water and engage in efforts to increase equitable access to clean water.
