In some countries basic infrastructure is lacking. Elsewhere, the infrastructure is inadequate because of age, state of disrepair, or incompetant management.
[Developing countries] Developing countries frequently lack adequate physical and social infrastructure of all kinds and their substantial improvement is essential for rapid economic development. In these countries, except in a few cities and towns, most areas are not served by modern transport and communications, and electric power is non-existent. Water supplies for domestic, agricultural and industrial use is limited. Sanitation facilities are non-existent for most people. Health and medical services are lacking. The educational infrastructure in developing countries is weakest in the sciences and technologies, resulting in a lack of technological expertise to bring to bear on agricultural and other key areas of production.
