In the framework of the programme for the achievement of MDG (MIllenium Development Goals) for water supply, UNICEF is promoting manual drilling throughout Africa; with different activities: advocacy, mapping of suitable zones, technical training and institutional support.Manual drilling refers to those techniques of drilling boreholes for groundwater exploitation using human or animal power (not mechanized equipment). These techniques are well known in countries with large alluvial deposits (India, Nepal, Bangladesh, etc). They are cheaper than mechanized boreholes, easy to implement as the equipment is locally done, able to provide clean water if correctly applied.But manual drilling is feasible only where suitable hydrogeological conditions are (shallow layers not to hard and groundwater not deeper than 25 m). Therefore a preliminary identification of suitable areas is necessary. The method for the identification of suitable zones at country levelalready aplied in 15 countries is based on the analysis of existing hydrogeological data. But an improved approach to have more reliable interpretation and more detailed analysis of the hydrogeological contex is required.The proposed research aims:- to contribute to define an improved methodology for the characterization of shallow geological conditions integrating other sources of indirect data- to produce more detailed suitability maps in the selected area, with the goal of supporting the implementation of manual drilling construction program.The research involves the collaboration of research centres and institutional partners in Italy, Senegal and Guinea. In particular these entities will participate:Univeristy of Milano Bicocca (Italy)University CHeick Anta Diop in Dakar (Senegal)UNICEF Senegal country officeUNICEF GUinea country officeSNAPE (National Water Authority) GuineaSchool of MInes Boke' - Guinea)

在实现供水千年发展目标方案框架内，儿童基金会正在整个非洲推广人工钻井，开展不同的活动：宣传、绘制适当区域图、技术培训和机构支助，人工钻井是指利用人力或畜力（而不是机械化设备）钻井开采地下水的技术。这些技术在拥有大量冲积矿床的国家（印度、尼泊尔、孟加拉国等）是众所周知的。与机械化钻孔相比，人工钻孔成本更低，易于实施，因为设备是在当地完成的，如果正确使用，能够提供清洁的水。但人工钻孔仅适用于水文地质条件合适的地方（浅层不太硬，地下水不超过25 m）。因此，有必要初步确定合适的区域。已在15个国家采用的在国家一级确定适宜区域的方法是以分析现有水文地质数据为基础的。但需要一种改进的方法来对水文地质背景进行更可靠的解释和更详细的分析。拟议的研究目标：-有助于定义一种改进的方法，用于表征浅层地质条件，整合其他间接数据来源-在选定区域制作更详细的适用性地图，目标是支持人工钻探施工计划的实施。该研究涉及意大利、塞内加尔和几内亚的研究中心和机构合作伙伴的合作。特别是这些实体将参加：米兰比可卡大学（意大利）达喀尔的Heick Anta Diop大学（塞内加尔）儿童基金会塞内加尔国家办事处儿童基金会几内亚国家办事处几内亚国家水务局几内亚博凯矿业学校
