Duties and Responsibilities

Background Water scarcity is a significant challenge for sustainable development, as it directly affects the ability to ensure access to water and sanitation for all, while also having important implications for energy and food security, economic development, as well as urban and rural livelihoods. Water security challenges caused by water scarcity also require national and regional security considerations and transboundary water cooperation to achieve global goals. Lebanon is becoming more and more reliant on groundwater resources with some aquifers already being depleted by over pumping by private wells or being affected by seawater intrusion. Data on groundwater is either unavailable or inaccessible or greatly dispersed across several private and public entities. The Ministry of Energy and Water, the main custodian for groundwater, has a need to update its groundwater database and develop geospatial analytical capacities of staff to better monitor groundwater resources, support groundwater wells licensing and inform management of the resources. This consultancy is intended to support the Ministry of Energy and Water in Lebanon to make significant use of geospatial information system (GIS) technologies for the review, digitization, classification and analysis of maps related to groundwater resources. The purpose is to facilitate the integration and analysis of various geospatial data layers that will contribute to the elaboration of a groundwater database in Lebanon and analysis for informed decision-making.
