The increasing slums in African cities, is due to the rising number of people moving from rural centres to the urban centre, Dr. Calvin Atewamba, Research Fellow, United Nations University said on Wednesday in Accra.
…Dr. Atewamba said over 20 years after the Rio Conference in 1992, the world is still facing many sustainable development issues, adding that, of particular concern were climate change, depletion of natural resources and degradation of biodiversity and the ecosystem services that underpin all life on earth, making sustainable development more difficult to achieve.
