Slum Upgrading in developing countries
The slum question is at the very heart to urban planning and social development. The urban growth takes place primarily in developing countries. Around one billion of people (with a perspective of 2 billion in 2030), the third of the world’s total urban population, live in such conditions of precariousness. Confronted with this demographic and spatial revolution, urban decision-makers are often helpless. The aim of this communication is to: 1) actualize the analysis of the phenomenon; 2) outline through a number of urban case studies in several emerging and developing countries, some relevant conditions that should be gathered to improve the human and built situation with a view to urban sustainable development.
