A clear focus makes it easier for people to understand sustainability and take action. The biosphere Eco-City provides this focus by dividing Sustainability into these specific 10 areas of interest called Themes of Sustainability.
People and organizations drive sustainability in a Biosphere Eco-City (BEC). Those most affected by problems are encouraged to work on solutions. An objective of BEC is to Involve Everyone, as explained in the Biosphere Eco-City Model.
Urban activities affect the surrounding countryside. Adjoining urban and rural areas can support each
other's sustainability, and cooperation can provide mutual benefits. Urban-Rural Cooperation is a priority in a Biosphere Eco-City.
