(Extract from the Executive Summary) Appropriate water resource development is an important component in ensuring sustainable livelihoods in Mandera District. In order to support planning activities within the water sector, Oxfam Quebec commissioned Rural Focus Ltd. to undertake a water source assessment and mapping assignment in Mandera District. The main objective of the assignment was to establish a GIS based database of water sources and related socio-economic data for Mandera District. A subsequent phase of the exercise was to use the GIS to develop a strategic plan for rehabilitation and management of existing water sources. A team consisting of members of the Pastoral Resource Team (PRT) of Mandera District and Oxfam Quebec assisted m the identification of the types of sources and information required. Data capture forms were developed and two teams covered Mandera District visiting in total 769 water sources. Relevant data for each source, covering the geo-referenced position, capacity, operational status, management system, demand etc. were obtained and entered into a Geographical Information System - (GIS)
