Special IWRM Study: Bilharzia / Schistosomiasis – vector snail prevalence and control in Lake Muhazi


To assess the opportunities for reduction of health issues caused by Schistosomiasis (Bilharzia) in the human populations around Lake Muhazi, by reduction of vector snails prevalence in Lake Muhazi and nearby water bodies, through ecosystem interventions.


International short term Bilharzia expert / aquatic ecologist


The specialist to be hired for this study is required to hold a Master’s level academic degree in aquatic ecology, hydrobiology, or comparable, preferably in vector biology of schistosomiasis, with knowledge of vector snail populations in the region, and have relevant experience in the fields of this ToR. Experience will comprise freshwater snails, their habitats and ecosystem relationships, and ecosystem interventions.

Input:                                            max 25 working days

Mission planning:

First mission October 2016 (ca. 10 days), second mission to be determined.

Relevant Background

The IWRM Programme, funded by the Government of The Netherlands through the Royal Netherlands’ Embassy in Kigali, supports the Rwanda Natural Resources Authority (RNRA) of the Ministry of Natural Resources in order to enhance capacities at national, catchment, and local (District) level with regard to catchment management and IWRM. The IWRM programme is supported by the IWRM Support Unit (ISU), a consortium of consultants working with the IWRM Department on a daily basis. In the framework of the programme, several studies will be implemented, to support the IWRM Department in particular, and the Government of Rwanda at large, in managing specific IWRM issues, or to support the development of catchment plans for the demonstration catchments of the programme.

Scope of Work

The main activities to be undertaken within the framework of this special IWRM study are as follows:

  1. Development of concise inception report;
  2. Baseline study on vector snails including ecological quick scan of the lake (including field visit) and selected surrounding water bodies, and tests in a laboratory if required.
  3. Assessment of the available documentation from University of Rwanda, RNRA, MINISANTE and the predator fish test from MINAGRI (PAIGELAC project; coordinator tel. nr. 0788306364);
  4. Study of other available documentation, such as the paper on Control of Schistosomiasis in Rwanda and relevant scientific publications;
  5. Discuss with relevant stakeholders (e.g. government and knowledge institutes) and with the epidemiologist of the schistosomiasis epidemiological team);
  6. Develop a long list of potential measures in close cooperation with the UoR team and the study team leader from W4GR (in the first mission);
  7. Assess (in the first mission) the preliminary expected effectiveness and viability of the most promising (short listed) measures, based on literature and discussions with ISU and IWRMD staff and other relevant stakeholders, taking into account the preliminary findings and results of a separate study into the long term water management options for Lake Muhazi ;
  8. Develop conclusions and recommendations on potential interventions and plan the contents of the second mission under guidance of the study team leader;
  9. Provide (in the second mission) a conceptual approach and detailed programme of measures for the reduction or eradication of schistosomiasis around Lake Muhazi, or minimally the local eradication of vector snails at sites where many people are in contact with water, including (if deemed feasible), a reduction of endemic schistosoma intermediate hosts in and around Lake Muhazi, taking into account the possibility of future changes in the management of Lake Muhazi (e.g. if the lake is turned into a multi-purpose reservoir with actively controlled water level fluctuations).
