The paper focuses on the application of system dynamics computer model in the waste generation and
its attendant challenges from the dumpsites of Ogo Oluwa Local Government Area (LGA), Nigeria.
Model equations were formulated to project the population of the study area. Pre-determined percent
organic contents of the wastes and temperature were the key variables employed in developing the
causal loops linking the population, economic status, and waste generation per capita in a STELLA flow
diagram. Simulated results show that population in the urban region increases sharply with time in the
first 25 years as against steady increase in the rural region. The community witnesses a continuous
increase in wastes, leachate and gas generation over the 100 years projection. The rate of gas
generation exceeds that of solid wastes at most given simulated times.
