项目摘要

The 'CONNECT4 water resilience' project brings together a multidisciplinary team of hydrologists and sociologists from academia, policy and practice in the UK, Botswana, South Africa, Zimbabwe and Mozambique to investigate the physical and societal factors affecting vulnerability and resilience to drought and floods in 4 countries of the Limpopo River Basin (LRB). The research will provide a better understanding of the connectivity within and between physical and social aspects of vulnerability to improve societal preparedness and resilience to flood and drought hazards in arid Sub-Saharan regions. The LRB is an arid, water-stressed basin, yet with high susceptibility to floods. It encompasses a large diversity of physical and socio-economical characteristics spread across four countries (Botswana, South Africa, Zimbabwe and Mozambique). Floods and droughts have been shown to exacerbate water availability and quality problems and are predicted to increase in frequency and magnitude.We will focus on the challenges and opportunities during floods following droughts in the LRB, when aquifers and communities are already under stress, and when appropriate flood management could improve short term coping mechanisms and long-term resilience for future dry seasons. We will explore to what extent geographical differences between sub-regions influence how water resources respond to, and how people cope with floods and droughts in order to inform appropriate water management strategies at various scales (local to transnational).The research will articulate around three integrated workpackages (WP). WP1 will assess basin-scale hydrological connectivity, i.e. how droughts and floods propagate in space and time under varying physical conditions (hydrometeorology, physiography, geology, groundwater-surface water interactions), with a focus on how the hydrological response of a specific sub-region influences or is influenced by other regions. This will be achieved though implementation of a basin-scale groundwater-surface water modelling approach and based on existing datasets, in part collected by the project team. Outputs will aid to improve transnational flood and drought monitoring networks and update susceptibility mapping.WP2 will assess the basin-scale social connectivity, i.e. how drought-flood cycles are understood, anticipated and worked with by local communities and how these communities interact with governance institutions. This will be achieved by carrying out interviews with diverse community groups and with key community-government intermediaries such as extension officers and catchment management fora. Outputs will contribute to understanding how drought/flood risk is perceived by communities and to develop better communication.WP3 will integrate WP1 and WP2 and will work on the connectivity between social and hydrological systems. It will connect our understanding of multiscale hydrological processes underlying alternating droughts and floods with water resource and risk management, and societal preparedness pathways. This aims to co-create management solutions to reduce impacts and increase benefits of drought-flood cycles throughout the LRB. It will use an iterative, co-production process to strengthen crucial bridges between scientists and water management stakeholders on the appropriate scale(s).Research outputs will impact (1) people in the LRB and arid regions through enhanced awareness and preparedness to flood and droughts, leading to increased resilience; (2) local and regional authorities via improved hydrological monitoring networks and a strengthened connection from local to transnational levels of governance; (3) general public through public engagement activities; (4) international academics via publications and socio-hydrological datasets on public databases, training of African under- and postgraduate students and development of early career researchers.

“CONNECT4水恢复力”项目汇集了来自英国、博茨瓦纳、南非、津巴布韦和莫桑比克的学术界、政策和实践领域的水文学家和社会学家组成的多学科团队，以调查影响干旱和洪水脆弱性和恢复力的自然和社会因素。林波波河流域 (LRB) 的 4 个国家。该研究将更好地了解脆弱性的物理和社会方面内部和之间的联系，以提高撒哈拉以南干旱地区洪水和干旱灾害的社会准备和抵御能力。 LRB 是一个干旱、缺水的盆地，但很容易遭受洪水侵袭。它涵盖了四个国家（博茨瓦纳、南非、津巴布韦和莫桑比克）的自然和社会经济特征的多样性。洪水和干旱已被证明会加剧水的供应和质量问题，并且预计其频率和程度都会增加。我们将重点关注 LRB 干旱后洪水期间的挑战和机遇，此时含水层和社区已经面临压力，而当适当的洪水管理可以改善短期应对机制和未来旱季的长期抵御能力。我们将探讨次区域之间的地理差异在多大程度上影响水资源的反应以及人们如何应对洪水和干旱，以便为不同规模（地方到跨国）的适当水资源管理战略提供信息。该研究将围绕三个方面进行阐述集成工作包 (WP)。 WP1将评估流域尺度的水文连通性，即干旱和洪水在不同的物理条件（水文气象、地理学、地质、地下水与地表水相互作用）下如何在空间和时间上传播，重点关注特定子系统的水文响应如何。区域影响其他区域或受其他区域影响。这将通过实施流域规模的地下水-地表水建模方法并基于现有数据集（部分由项目团队收集）来实现。产出将有助于改善跨国洪水和干旱监测网络并更新敏感性测绘。WP2 将评估流域规模的社会连通性，即当地社区如何理解、预测和处理旱涝循环，以及这些社区如何与治理机构互动。这将通过与不同社区团体和主要社区政府中介机构（例如推广官员和流域管理论坛）进行访谈来实现。产出将有助于了解社区如何看待干旱/洪水风险，并促进更好的沟通。WP3 将整合 WP1 和 WP2，并将致力于社会和水文系统之间的连通性。它将我们对干旱和洪水交替背后的多尺度水文过程的理解与水资源和风险管理以及社会准备途径联系起来。其目的是共同创建管理解决方案，以减少整个LRB旱涝循环的影响并增加其效益。它将采用迭代、联合生产流程，以适当的规模加强科学家和水管理利益相关者之间的重要桥梁。研究成果将通过提高对洪水和干旱的认识和准备，影响 (1) LRB 和干旱地区的人们。干旱，提高抵御能力； (2) 地方和区域当局通过改进水文监测网络和加强地方与跨国治理层面的联系； (3) 通过公众参与活动向公众开放； (4) 国际学者通过公共数据库上的出版物和社会水文数据集、非洲本科生和研究生的培训以及早期职业研究人员的发展。
