ENVIRONMENTAL
Environmental causes of migration include natural disasters, such as flooding.
It must be noted that some people are forced to migrate, e.g., those who move
due to war or famine, such as refugees or individuals seeking asylum. A refugee
is someone who has left his home and seeks somewhere to settle in comfort and
freedom from fear.
TERMS USED TO EXPLAIN MOVEMENTS OF THE POPULATION
Push factors: These are the reasons people leave an area which include a lack
of services, lack of safety, high crime, crop failure, drought, flooding, poverty,
war and so on.
Pull factors: Reasons people move to a particular area, including higher
employment rate, more wealth, better services, good climate, safer environment,
less crime, political stability, more fertile land, lower risk from natural hazards,
and so on.
Migration usually happens as a result of a combination of these push and pull
factors.
RURAL AND URBAN MIGRATION
One noticeable issue in the society today is the rate at which people migrate
from the rural to the urban areas. One of the factors responsible for rural-to-
urban migration is the lack of or inadequate social amenities and facilities in the
rural areas. These include piped water, electricity, good roads, hospitals,
schools, recreational centres, and so on. Inadequate and varied jobs in the rural
areas also cause many youths to migrate to the urban areas, in the hope of
finding better opportunities for themselves.
Rural-to-urban migration has negative consequences. It leads to overpopulation
of the urban areas, thus encouraging crime in the society. Rural-to-urban
migration also slows down the rate of development of the rural areas.
