This pattern slowed due to the 1975 Land Reform program instituted by the government, which provided incentives for people to stay in rural areas. As people moved from rural areas to the cities, there were fewer people to grow food for the population. The Land Reform Act was meant to increase agriculture since food production was not keeping up with population growth over the period of 1970–1983. This program encouraged the formation of peasant associations, large villages based on agriculture. The legislation did lead to an increase in food production, although there is debate over the cause; it may be related to weather conditions more than the reform. Urban populations have continued to grow with an 8.1% increase from 1975 to 2000.
