This conference on "Sustainability and Urban Growth in Developing Countries" (DIMSUD Conference 2004) plans to highlight urbanization in the rapidly growing cities of the developing world. World-wide urbanization is one of the most powerful forces influencing global sustainability prospects today. The convergence of population growth and urban expansion offers great potential as well as great challenges for achieving metropolitan sustainability. Perhaps nowhere are these factors more dominant than in the developing countries. This conference will address the challenges of urbanization for African, Latin American and Asian agglomerations and discuss alternatives that could lead to sustainable urban development.
