Effectiveness of participatory monitoring and evaluation on achievement of community-based water projects in Tanzania

The Government of Tanzania is struggling to implement water projects throughout the country to ensure that 90% of the population has access to clean and safe drinking water by 2025. While most of the community-based water projects fail to deliver as expected, participatory monitoring and evaluation (PM&E), critical for projects' achievement, is at an infancy stage. This article determines effectiveness of PM&E on achievement of community-based water projects' objectives. The article adopted sequential exploratory research design to collect quantitative and qualitative data. A random sample of 120 water users in the government and NGOs funded projects was involved whereby 53.3% were women. Focus group discussions (FGDs) and key informant interviews were used to collect qualitative data. SPSS was used to summarize descriptive statistics. Kruskal–Wallis H test was used to compare median differences between the projects, while qualitative data were subjected to content analysis. Overall, 51.7% of the respondents reported that community-based water projects' objectives were achieved except capacity building. The projects funded by NGOs recorded high achievement relative to the government funded projects. In addition, PM&E was effective in achieving water projects' objectives. There was a statistically significant difference in responses between low, medium and high effectiveness of PM&E (P ≤ 0.05). Majority reported high effectiveness, more so for NGOs-funded water projects. The article concludes that PM&E was effective in achieving projects' objectives except capacity building. Therefore, it recommends strengthening of capacity building for the local communities to manage community-based water projects effectively. This is a policy issue that needs serious efforts at all levels of the government.
