Abstract	An overview of progress during the past 30 years in the hydrogeologic understanding of groundwater in hard-rock aquifers of tropical regions is presented. Geographically, the paper concentrates upon and contrasts Tropical Africa and Peninsular India, where very extensive areas of weathered hard-rock aquifers occur, but its conclusions are more widely applicable. This scientific understanding forms the basis for a critical discussion of key policy issues for the development and management of the water resources of these aquifers, given their major importance for economical and sustainable water-supply provision, in the context of efforts to achieve the UN Millennium Development Goals for rural drinking water and improved livelihoods.Un aperçu des progrès réalisés durant les 30 dernières années dans la compréhension de l’hydrogéologie des aquifères en roches massives en régions tropicales est présenté. Quant à la géographie, l’article focalise sur l’Afrique tropicale et la compare à la Péninsule indienne, régions où se présentent des zones très étendues d’aquifères en roches massives altérées, mais ses conclusions sont applicables de manière plus générale. Cette lecture scientifique sert de base à une discussion critique des questions de politiques clef du développement et de la gestion des ressources de ces aquifères, étant donnée leur importance majeure pour la fourniture économe et durable d’un approvisionnement en eau, dans le cadre des efforts consentis pour atteindre les Objectifs de Développement du Millénaire des Nations Unies en matière d’eau potable en zone rurale et d’amélioration des moyens d’existence.Se presenta una visión general de los progresos realizados durante los últimos 30 años en la comprensión hidrogeológica del agua subterránea en los acuíferos de roca dura de las regiones tropicales. Geográficamente, el trabajo se concentra en los contrastes de África tropical y de la India peninsular, donde se existen muy extensas áreas de acuíferos de rocas duras meteorizadas, pero estas conclusiones son aplicables ampliamente. Esta comprensión científica forma la base de una discusión crítica de los problemas claves de la política para el desarrollo y manejo de los recursos hídricos de estos acuíferos, dada su gran importancia para la provisión económica y sustentable del abastecimiento de agua, en el contexto de los esfuerzos para lograr las metas de desarrollo del milenio de las Naciones Unidas para el abastecimiento de agua rural y para el mejoramiento de los medios de subsistencia.本文对过去30年里热带地区硬岩含水层中关于地下水的水文地质认识进展进行综述。地域上,本文集中并对比了风化坚硬岩石含水层区域广泛分布的热带非洲以及印度半岛,但结论可广泛应用。在努力实现联合国农村饮用水及改善生计的千年发展目标的背景下,这种科学认识可为含水层水资源开发与管理关键政策问题的关键讨论打下基础,对经济发展和可持续供水意义重大。É apresentada uma panorâmica dos progressos na compreensão hidrogeológica das águas subterrâneas em aquíferos fraturados de regiões tropicais, durante os últimos 30 anos. Geograficamente, o artigo centra-se sobre os contrastes entre a África Tropical e a Índia Peninsular, onde ocorrem áreas muito extensas de aquíferos em rochas fraturadas alteradas, mas as suas conclusões são aplicáveis a muitas outras regiões. Essa compreensão científica forma a base para uma discussão crítica das questões políticas chave para o desenvolvimento e gestão dos recursos hídricos desses aquíferos, dada a sua grande importância para o abastecimento de água de forma económica e sustentável, no contexto dos esforços para alcançar as Metas de Desenvolvimento do Milénio da ONU para a água potável e o melhoramento dos meios de subsistência.
