Programme of action of the Internatíonal conference on population and development - Chapter IX: Population distribution, urbanization and internal migration - B. Population growth in large urban agglomerations

Basis for action

9.12. In many countries, the urban system is characterized by the overwhelming preponderance of a single major city or agglomeration.

The tendency towards population concentration, fostered by the concentration of public and private resources in some cities, has also contributed to the rising number and size of mega-cities. In 1992, there were 13 cities with at least 10 million inhabitants and their number is expected to double by 2010, when most mega-cities will be located in the developing countries. The continued concentration of population in primate cities, and in mega-cities in particular, poses specific economic, social and environmental challenges for Governments. Yet large agglomerations also represent the most dynamic centres of economic and cultural activity in many countries. It is therefore essential that the specific problems of large cities be analysed and addressed, infull awareness of the positive contribution that large cities make to national economic and social development. The challenges faced by cities are often exacerbated by weak management capacities at the local level to address the consequences of population concentration, socio-economic development, environmental impacts and their interrelations.

Objective

9.13. The objective is to enhance the management of urban agglomerations through more participatory and resource-conscious planning and management, review and revise the policies and mechanisms that contribute to the excessive concentration of population in large cities, and improve the security and quality of life of both rural and urban low-income residents.

Actions

9.14. Governments should increase the capacity and competence ofcity and municipal authorities to manage urban development, to safeguard the environment, to respond to the need of all citizens, including urban squatters, for personal safety, basic infrastructure and services, to eliminate health and socialproblems, including problems of drugs and criminality, and problems resulting from overcrowding and disasters, and to provide people with alternatives to living in areas prone to natural and man-made disasters.

9.15. In order to improve the plight of the urban poor, many of whom work in the informal sector of the economy, Governments are urged to promote the integration of migrants from rural areas into urban areas and to develop and improve their income-earning capability by facilitating their access to employment, credit, production, marketing opportunities, basic education, healthservices, vocational training and transportation, with special attention to the situation of women workers and women heads of households. Child-care centres and special protection and rehabilitation programmes for street children should be established.

9.16. To finance the needed infrastructure and services in a balanced manner, taking into account the interests of the poor segments of society, local and national government agencies should consider introducing equitable cost-recovery schemes and increasing revenues by appropriate measures.

9.17. Governments should strengthen the capacity for land management, including urban planning, at all levels in order to take into account demographic trends and encourage the search for innovative approaches to address the challenges facing cities, with special attention to the pressures and needs resulting from the growth of their populations.

9.18. Governments should promote the development and implementation of effective environmental management strategies for urban agglomerations, giving special attention to water, waste and air management, as well as to environmentally sound energy and transport systems.
