"Around one in seven of the world's populations live in informal settlements in urban areas. City economies would collapse without their labour and the goods and services from informal enterprises - yet city governments often ignore them or see them only as a problem ... The Asian Coalition for Community Action (ACCA) sees these people, and the grassroots organizations they form, as the basis for urban development. Since 2009, ACCA has developed a working finance system in which urban poor organizations have the power to choose what they will undertake." (Quoted from article)
