These conditions restrict growth. Strategies for promoting the demand for labour in informal sectors, therefore, should not be limited to the mere integration of the informal and formal economies. Harris stresses the importance of other requirements for improved productivity. The provision of credit, training and land. Reducing urban poverty depends on general access to infrastructure, as well as an increased demand for labour.

The IBRD reports that past donor urbanization initiatives have focused on low-cost investment projects in shelter, water supply, sanitation and urban transport. Performance audits of many such initiatives, however, revealed that the intended widespread replication did not take place. The World Bank's Rabat and Second Urban Development Project serves as a good case in point of such a failure. Adherence to IBRD's suggested criteria would appear integral for effective reassessments and priority settings of urban development projects. Effective solutions to urbanization issues are becoming increasingly critical.
