Ngerengere River

COMMUNITY-BASED BIOASSESSMENT OF WATER QUALITY ALONG NGERENGERE RIVER USING MACRO-INVERTEBRATES AS BIOINDICATORS

PROJECT PURPOSE AIM AND GOALS

Project Duration July – August 2018

The project has applied a citizen science, participatory approach by training community and actors along Ngerengere river and use them to sample macro-invertebrates as Bioindicators to determine water quality status along the river. This is a robust, easy to apply, sensitive, fast, cost-effective and relatively easy to interpret method for monitoring water quality. The project has communicated the results to the stakeholders of water quality management through a workshop, discuss with stakeholders on possible long-term measures to safeguard the water health of Ngerengere river and the health of its dwellers.

The project has also established a volunteering group “Friends of Ngerengere river” consisting of representatives from the community and all actors that will be involved in water quality monitoring from time to time. This will ensure water quality is maintained from time to time due to different activities as they get established along the river, it will also strengthen participation and cooperation between communities and actors towards responsible Integrated Water Resource Management in Ngerengere catchment region.

Monitoring and assessment of water quality to assess the impact of various activities are challenging in developing countries when considering the costs of equipment, time and number of physicochemical parameters to be measured to conclude about overall quality status of water. Biomonitoring using macroinvertebrates provides a cheap, simple and fast way for monitoring the quality of water for community health.

Goals of the research project were;

  • To assess the quality of water along Ngerengere river using benthic macroinvertebrates as bioindicators.
  • To Promote Citizen Science by involving community in field work to trace the source (s) of pollution.
  • Enhance Integrated bottom-up water resource management approach in identifying, understanding and laying sustainable solutions for responsible water resource management
