The regions of south Madagascar have the country’s lowest water supply coverage and is highly vulnerable to chronic drought. Access to potable drinking water is a major challenge for the local population and many of the 11.7 million people in southern Madagascar have no access to safe water. Response consists of providing drinking water through the drilling of boreholes, but faces multiple constraints due to the scarcity and poor quality of groundwater. Tracking groundwater fluctuations are important to foreseen the risk of declining water levels and quality, and allow conservation practices to be triggered. Currently, there is no national monitoring system in Madagascar to estimate risks of groundwater depletion and provide information to water actors and humanitarians for a better planning of water resources exploitation. Therefore, there is an urgent need to develop a strategy and partnership with all stakeholders for the continuous monitoring of aquifer water levels including the variation of rainfall.
The objective of this consultancy is to put in place a groundwater early warning system (GEWS) to monitor the resource availability and quality in 8 drought-prone districts of southern Madagascar (Betioky, Ampanihy, Bekily, Beloha, Tsihombe, Ambovombe, Amboasary and Taolognaro). Measuring groundwater levels and precipitation is critically important for identifying long-term trends including declining water levels and saltwater intrusion, seasonal variations, aquifer recharge and level status of drinking water. The proposed GEWS concerns the monitoring of aquifers water levels, small and medium scale systems available in the study regions, and it will be implemented at three levels:
– Level 2: Manual GEWS – Piezometric probes/EC meters will be installed on specific small and medium systems to monitor groundwater fluctuations.
– Level 3: Community-based GEWS – local population monitor the functioning of handpumps in community and provide qualitative information on water availability and quality to a contractor.
The monitoring of the groundwater levels will be associated with rainfall measurement through meteorological stations. The number and localization of these meteorological stations will depend on the heterogeneity of the study area. Additionally, the Consultant will oversee the installation of all data loggers and meteorological stations including all related equipment.
1. Develop a strategy and partnership with all stakeholders (National/international NGOs, Universities and Government) for the continuous monitoring of aquifer water levels and the variation of rainfall;
2. Oversee the installation of all data loggers/piezometric probes/meteorological stations and all related equipment, and collect the required data over the 8 districts of the study area;
3. Processing and analysis of all data to produce relevant information on the depletion of aquifers level and variation of rainfall;
4. Establish a database for the monitoring aquifers and climatic conditions;
5. Coordinate activities with partners such as WFP to discuss and develop a strategy to integrate the data collected into the food early warning systems;
6. Collaborate with universities for the training of the national team to facilitate data collection at all study sites, and to establish a strategy for the sustainability of aquifer levels/rainfall monitoring in the south of Madagascar.
1. Technical proposition on the development of the GEWS including the methodology, type of equipment, analysis of data and a plan for local capacity building;
2. Hydrogeological report to summarize the geological/hydrogeological context of the study area and identify the homogenous zones were data loggers and meteorological stations will be installed for a better monitoring of the aquifers water levels and variations of rainfalls.;
3. Monthly progress report on the development and implementation of the GEWS;
4. Report on training and capacity building of Universities/local partners;
5. Monthly alert bulletin on the variation of aquifers water levels of and precipitations for diffusion to all partners of the water sector;
6. Final report on the entire project including future perspectives.
The hired consultant will report to the Chief of WASH and will work in close collaboration with the WASH Specialist for guidance and general supervision.
2. A minimum of five (5) years of progressively responsible professional work experience, at the national and international levels, in WASH water resource management, hydro-meteorology, hydrogeological studies and groundwater monitoring with an international organization, national institution or NGOs.
3. Strong field experience and knowledge of the hydrogeological context of southern regions of Madagascar is required.
4. Experience of hydrogeological studies and supervision of drilling projects for the supply of drinking water in rural areas is an asset
5. Experience of piezometric monitoring of boreholes and other water points is an asset
6. Fluency in French and English is required. Knowledge of a local language is an asset
