The paper first describes the interactions between population growth,
land use, and environment in Rwanda, a small, densely populated landlo
cked nation in the East-African Great Lakes region. These interactions
are modelled using a conceptual framework applied to the neighboring
Kivu region in Zaire, but adapted to the Rwandan case study. Second, t
he paper contends that the emphasis put on increasing agricultural pro
duction, mostly through the use of marginal land, as well as the lack
of a timely implementation of a family planning program and a national
population policy, have led to a worsening of the interactions betwee
n population growth, land use, and environment. In an attempt to demon
strate this hypothesis, demography-driven projection scenarios are app
lied to the agricultural colonization and intensification processes.
