Urban biosphere reserve

rdf:langString Urban biosphere reserve

rdf:langString An urban biosphere reserve is an attempt to apply the biosphere reserve concept to urban areas by the MAB Programme of UNESCO. Through urban planning and ecosystem management, an urban biosphere reserve is expected to support sustainable development and conservation. Brighton and Hove is bidding to become the world's first urban biosphere reserve. The need for urban biosphere reserves has arisen as the number of people living in the world's cities has reached three billion, nearly half of the total population. By 2050 two-thirds of the total population will be living in the cities. The rapid expansion of the cities and of their populations pose a challenge for a viable global environment. Although some of the existing biosphere reserves include cities and towns, entirely urban-oriented biosphere reserves have yet to be included in the list.
