Biosphere reserves contribute to sustainable development by being model areas in support of Agenda 2030. In a biosphere reserve, new methods are tested and new knowledge is sought to provide examples of how we can preserve a natural area while people live there. The biosphere program is based on local commitment to sustainable development with the motto "local solutions on global challenges". There are just over 700 biosphere reserves around the world. In Sweden there are currently seven biosphere's and Vombsjösänkan is running for becoming the eighth.
