However, migration is also prompted by push factors, such as inequitable allocation of development resources, adoption of inappropriate technologies and lack of access to available land. The alarming consequences of urbanization visible in many countries are related to its rapid pace, to which Governments have been unable to respond with their current management capacities and practices. Even in developing countries, however, there are already signs of a changing pattern of population distribution, in the sense that the trend towards concentration in a few large cities is giving way to a more widespread distribution in medium-sized urban centres. This movement is also found in some developed countries, with people indicating preference for living in smaller places. Effective population distribution policies are those that, while respecting the right of individuals to live and work in the community of their choice, take into account the effects of development strategies on population distribution.
Urbanization has profound implications for the livelihood, way of life and values of individuals.
Governments formulating population distribution policies should ensure that the objectives and goals of those policies are consistent with other development goals, policies and basic human rights. Governments, assisted by interested local, regional and intergovernmental agencies, should assess on a regular basis how the consequences of their economic and environmental policies, sectoral priorities, infrastructure investment and balance of resources among regional, central, provincial and local authorities influence population distribution and internal migration, both permanent and temporary. To create an enabling context for local development, including the provision of services, Governments should consider decentralizing their administrative systems. This also involves giving responsibility for expenditure and the right to raise revenue to regional, district and local authorities. While vast improvements to the urban infrastructure and environmental strategies are essential in many developing countries to provide a healthy environment for urban residents, similar activities should also be pursued in rural areas.
