REPUBLIQUE DU NIGER - ETUDE DE FAISABILITE DES FORAGES MANUELS - IDENTIFICATION DES ZONES POTENTIELLEMENT FAVORABLES

Dans le cadre de son Programme de coopération avec les Gouvernements pour améliorer l’accès à l’eau potable dans les pays africains, et avec l’objectif de faciliter la dissémination des technologies à faible coût (notamment les techniques de forage manuel), l’UNICEF est en train de développer une activité orientée à l’analyse des informations existantes et à la réalisation de la cartographie pour identifier les zones favorables aux forages manuels.

L’objectif de la présente étude est d’évaluer l’aptitude des zones potentielles du Niger pour la réalisation des forages manuels destinés à l’alimentation en eau potable des zones rurales du pays. Il s’agit d’une première approche, d’un outil pour définir une stratégie d’intervention (en termes de zones prioritaires, des techniques à utiliser, etc..) dans les zones favorables. | »

Groundwater’s Contribution to Water Security in Africa UPGro Working Paper

This paper has been prepared by researchers within the UPGro (Unlocking the Potential of Groundwater for the Poor) Programme, along with colleagues from the International Association of Hydrogeologists, Africa Groundwater Network, and GRIPP. It is intended as a working paper, presenting a summary of our current understanding of groundwater in Africa along four themes: (1) urban water security, (2) socially inclusive and sustainable rural water services, (3) groundwater for agricultural growth and transformation, and (4) groundwater resources and renewability. | »

Manual Drilling Compendium 2015 RWSN Publication 2015-2

Manual drilling refers to several drilling methods that rely on human energy to construct a borehole and complete a water supply. The various techniques can be used in areas where formations are quite soft and groundwater is relatively shallow.

Manual drilling can provide safe drinking water. The equipment can easily be transported to remote, or difficult to serve populations which would otherwise be left behind. The lower costs compared to machine drilling are appreciated by households, businesses and governments. Manual drilling also provides local employment.

Manual drilling methods are being used to provide water for drinking and other domestic needs at least 36 countries around the world. In some places, manual drilling methods are well established.

The compendium provides a useful overview for those wishing to further examine the impacts and challenges of manual drilling, and, more importantly, improve practices on the ground. It is hoped that the document will spur others to undertake fur-ther studies as well as research to document stories and analyse the promotion, uptake and use of manually drilled boreholes. In addition, the compendium should also enable those promoting manual drilling to realise that they are certainly not alone in their endeavours! | »

Handpump Standardisation in Sub-Saharan Africa: Seeking a Champion RWSN Publication 2015-1

Handpump standardisation is the formal or informal mechanism that governs the varieties of community handpumps used within a particular country. In a handful of countries this also includes stand-ard handpump designs. With over a million handpumps in sub-Saharan Africa and new installations every day, handpump standardisation is still vital for the policy and practices of governments and implementing organisations. While rural water practitioners are polarised about the future of formal standardisation, the extent of informal standardisation is of significant importance to the sustain-ability of handpumps across the continent. Of the thirty-five countries in sub-Saharan using handpumps, formal standardisation has emerged in fifteen through regulations (nine countries), and endorsements (six countries). However in the remaining countries, informal standardisation determines what handpumps are installed where, either through recommendations (fourteen countries), or de facto standardisation (six countries). | »
