Abstract:
The quality of the environment in the city of Kampala is deteriorating. The city needs a novel waste management approach to improve the environmental quality in its heterogeneous settlement patterns. Earlier, an integrated urban waste flow model (IUWFM) was applied to project the future waste flows and their impacts on the environment of Kampala using four waste management scenarios. These scenarios were ‘business-as-usual’, ‘more enforcement’, ‘more collection’ and ‘proper management’. The robustness of the scenario results was determined by using a multi-criteria decision analysis. Twenty-four criteria were identified and grouped as environmental, economic, social, technological and general. Equal weights were assigned to these five sets of criteria. The four scenarios were evaluated against all criteria, and a sensitivity analysis was performed on the role of the equal weights on the choice of the scenarios. The results showed that ‘proper management’ scenario, which integrates diverse technologies and management programs matching with the local context, is the optimal approach to improve Kampala’s environmental quality. Scenarios that emphasized more waste collection, but less resource recovery were ranked in the middle. The scenario of maintaining the status quo performed worst. Application of a mix of diverse technologies and management programs matching the local conditions is the most optimal solution to improve Kampala’s environmental quality.
