Groundwater

WHY DOES GROUNWATER MATTER?

  • Groundwater is a critical resource for providing drinking water, irrigation for agriculture, and supporting ecosystems. It is estimated that 2.5 billion people globally rely on groundwater for their daily needs [UNESCO, 2012]. However, groundwater resources are finite and can be depleted or rendered unsafe due to contamination, causing a threat to water security, particularly in arid and semi-arid regions. Over-extraction causes such severe impacts as land subsidence, seawater intrusion, and drying of streams, ultimately leading to environmental degradation and a loss of ecosystem services. 

  • Groundwater contamination is another major issue that threatens groundwater sustainability. Emerging contaminants such as per- and polyfluorinated substances (PFAS), legacy pollutants such as heavy metals, and natural pollutants such as fluoride and arsenic can have severe impacts on human health, ecosystems, and societies. Therefore, effective groundwater management requires monitoring, regulation, and remediation of contaminated groundwater resources. 

 

WHY A NEXUS APPROACH?

Groundwater sustainability is a complex and multi-dimensional issue that requires a holistic approach. Groundwater resources are connected to various interfaces such as soils, wetlands, and coastal waters, making it challenging to manage sustainably. To address this challenge, the UNU-FLORES Resource Nexus Analytics, Informatics, and Data (AID) Programme offers a Groundwater Sustainability module that adopts a resource nexus approach. 

A resource nexus approach combines different disciplines and sectors, such as big data, the economy, socio-economy, and social aspects, to address complex and interconnected environmental and social issues. The groundwater sustainability module aims to promote a resource nexus approach by identifying and promoting information, data, computational techniques, and analytical tools that facilitate the sustainable management of groundwater resources. 

The module focuses on three main pillars: 

  • Groundwater Data: This pillar aims to facilitate data exchange and fill the data gaps for analyzing groundwater systems. It inventories existing groundwater data and identifies the data gaps using a problem-driven approach that helps governments, societies, and businesses tackle global environmental challenges. 

  • Groundwater Informatics: This pillar aims to build and improve the capacity for computing and processing groundwater data. It develops and promotes state-of-the-art tools and best practices to store, process, analyze, and manage groundwater data in coupled human-environment systems. 

  • Groundwater Analytics: This pillar aims to facilitate the extraction of information from data and inform decision-making by inventorying, developing, and promoting state-of-the-art groundwater analytical tools and frameworks. 

By promoting a resource nexus approach, the groundwater sustainability module aims to provide unique datasets and toolkits from multiple disciplines to address the grand challenges related to sustainable groundwater management. These challenges align with the UN Sustainable Development Goals and require a multi-dimensional approach to be effectively addressed. 

AID TOOLS

These pillars provide various tools and resources to help manage groundwater resources sustainably. By promoting groundwater sustainability and using tools like those offered by the Groundwater Sustainability module, we can ensure that groundwater resources are managed effectively and efficiently to support human needs, protect ecosystems, and ensure their availability for future generations. Some of the tools and resources include:
