项目摘要

The Groundwater Futures in Sub-Saharan Africa (GroFutures) project will assemble an inter-disciplinary team of highly experienced physical and social scientists from Africa and Europe to generate new scientific evidence and methods to enable groundwater to be used sustainably and equitably tom improve the lives of poor people in Sub-Saharan Africa (SSA) by way of improved access to safe water for drinking and domestic purposes as well as water for agricultural production. As SSA is a region of small-scale farmers, sustainable year-round access to water for agriculture is a core component of poverty alleviation strategies in this region. GroFutures also recognises the importance of protecting the quantity and quality of groundwater discharges that sustain rivers, lakes and wetlands and the benefits (e.g. fish, hydropower) derived from these.Under a one-year catalyst grant, the GroFutures Team will work with government water ministries in Ethiopia, Ghana and Tanzania to conduct a series of pilot studies characterising and quantifying seasonal changes in groundwater demand under a range of potential development options including increased use of groundwater for irrigation as well as urban and rural water supplies in selected basins. Indicative changes in groundwater supply by way of rain-fed groundwater replenishment (recharge) will also be evaluated under this pilot research by examining relationships between climate and groundwater recharge in semi-arid (central Tanzania) and seasonally humid (northern Uganda) environments where long-term observational records exist. The evaluation will focus on observed recharge responses to changes in the intensity of rainfall that is projected to increase in a warmer world, under these contrasting climate regimes.A significant innovation of the research conducted under this catalyst grant is the development and trial of a new metric of water availability that, for the first time, explicitly considers groundwater resources. Water availability will be redefined in terms of water storage requirements, be it natural (e.g. groundwater) or constructed (e.g. surface reservoirs), that are required to address imbalances between water supply and demand. As such, the metric will directly inform water management including sustainable allocations of groundwater. Because access to groundwater often disfavours poor water users, GroFutures will investigate pathways to enhance the governance and management of groundwater that recognise and support access of the poor to groundwater.The interdisciplinary GroFutures Team is uniquely qualified to undertake the proposed research. It has conducted pioneering research evaluating factors that influence groundwater demand and supply and, as such, possesses invaluable long-term and detailed datasets as well as an acute understanding of the national development plans required to develop robust projections and scenarios of the future with which to determine the sustainability of groundwater resources in different settings. Having enjoyed long-term collaborations with government ministries who are project partners, the team is also able to review critical questions of groundwater governance and management.Another key attribute of the GroFutures proposal is the holding of a pan-African workshop which will enable a rare opportunity for scientists in Anglophone and Francophone Africa to share their experiences and expertise. Scientists and government stakeholders in the GroFutures project will run the workshop jointly with a Francophone network of researchers, PICASS'EAU, from Benin, Burkina Faso, Cameroon, Chad, Côte d'Ivoire, Niger, and Nigeria as well as potentially other UPGro Consortia and several invited international scientists who will examine the wider applicability of GroFutures pilot-study results to SSA and inform research to be proposed under a subsequent large, inter-disciplinary consortium proposal to the UPGro programme.

撒哈拉以南非洲（Grofutures）项目的地下水未来将组成一个由非洲和欧洲的经验丰富的物理和社会科学家组成的跨学科团队，以产生新的科学证据和方法，以使地下水能够可持续地使用，并同样可以通过饮用水和饮用水来供水，从而改善了萨哈兰非洲地区（SSA）的穷人生活。由于SSA是小型农民的一个地区，因此全年可持续获得农业水是该地区贫困策略的核心组成部分。绒毛还认识到保护河流，湖泊和湿地的地下水排放的数量和质量的重要性选项包括增加地下水灌溉以及所选基地中的城市和粗糙水供应。在这项试点研究中，还将评估地下水供应（补给）的指示性变化（补给），通过检查攀岩和季节性潮湿（乌干达北部）环境的攀岩和地下水补给之间的关系，在存在长期观察记录的情况下。评估将集中于观察到的补给反应，对降雨强度的变化，预计在这些对比的气候制度下，预计将增加降雨量，这将在较温暖的世界中增加。根据该催化剂赠款进行的研究的重大创新是对新的水量可用性的开发和试验，这是首次明确考虑地面层面的水。水的储能需求将被重新定义，无论是自然的（例如地下水）还是构造的（例如地面储备），这是解决水供应和需求之间不平衡所必需的。因此，该指标将直接告知水管理，包括可持续的地下水分配。由于进入地下水经常会使贫穷的用水使用者脱颖而出，因此Grofutures将调查途径，以增强地下水的治理和管理，这些途径和管理认识和支持穷人进入地下水。它已经进行了开创性的研究评估因素，这些因素影响地下水需求和供应，因此拥有宝贵的长期和详细的数据集，以及对开发强大的未来项目和场景所需的国家发展计划的敏锐理解，以确定不同环境中地下水资源的可持续性。该团队享受了与项目合作伙伴的政府部门的长期合作之后，还能够回顾地下水治理和管理的关键问题。毛lofutures提案的另一个关键属性是举办泛非研讨会，这将使科学家在Anglophone和Francophone非洲分享他们的经验和专业知识。 Glofutures项目中的科学家和政府利益相关者将与贝宁，伯基纳法索，喀麦隆，喀麦隆，乍得，科特迪瓦，尼日尔，尼日尔和尼日利亚和尼日利亚以及一些邀请的国际科学家和纽约市的其他景点的杂物相关的研究人员和尼日利亚的应用程序，从研究将根据随后向UPGRO计划提出的大型大型跨学科联盟提案提出。
