The unprecedented pace and scale of the proliferation of slums and informal settlements pose a major challenge to cities of developing countries like the Philippines and the international community. The numbers on slum dwellers are appalling and necessitate a global response. Data reveal that in 2000, there were 94 million urban poor/slum dwellers in the world’s cities (more than 20% of the world population). By the year 2020, an additional 500 million will be added to the figure making it 1.424 billion urban poor/slum dwellers. And that by 2030, urban poor or slum population will have reached the 2 billion mark.
