Assessing the Effectiveness of Environmental Protection and Management Systems on Environmental Sustainability: A Case Study of Kigali City
Abstract
This study assessed the effectiveness of environmental protection and management systems in promoting environmental sustainability in Kigali City, Rwanda. A mixed-methods research design was employed to examine the contribution of environmental policies, institutions, implementation mechanisms, and stakeholder participation to sustainable environmental outcomes. Quantitative data were collected from 400 household respondents selected through stratified random sampling across the districts of Gasabo, Kicukiro, and Nyarugenge, while qualitative data were obtained from purposively selected key informants, site observations, and document review. The sample size was determined using Yamane’s formula. Quantitative data were analysed using descriptive statistics, specifically frequencies and percentages, and presented through tables and figures, while qualitative data were analysed using thematic content analysis to identify key patterns and perspectives. The findings revealed that Rwanda has established comprehensive environmental policies, regulations, and institutional frameworks that have significantly contributed to environmental sustainability in Kigali City. Environmental protection and management systems have improved environmental outcomes through effective waste management, green urban planning, environmental impact assessments, wetland restoration, biodiversity conservation, and community participation. These interventions have enhanced environmental conservation and supported sustainable urban development. However, the study identified several challenges limiting effectiveness, including inadequate funding, weak enforcement of environmental regulations, limited technical and institutional capacity, insufficient community participation in decision-making, and coordination gaps among stakeholders. The study concludes that environmental protection and management systems have made substantial contributions to environmental sustainability in Kigali City, although implementation and governance challenges continue to constrain their full effectiveness. It recommends strengthening environmental law enforcement, enhancing institutional coordination, increasing financial and technical support, and promoting participatory and sustainable urban planning practices to improve long-term environmental sustainability.
