The scientific foundation for proactive water resilience

ACADEMIC BASE

Research developed to support better decisions.

Every region is geographically and socioeconomically unique. Water vulnerability is therefore not determined by natural availability alone. A region with limited supply may remain resilient through reliable infrastructure, coordinated governance, and diversified sources. Conversely, a water-rich region can still be exposed when system losses, environmental degradation, or inadequate planning weaken the system.

ÆGIR RESILIENCE believes that, despite technological progress, history can repeat itself when physical, environmental, infrastructural, and societal vulnerabilities are not considered as part of a wider system. We therefore assess water vulnerability through the interaction of these factors.

PUBLICATIONS

Peer-reviewed and publicised research

The backbone of ÆGIR RESILIENCE is the academic research on which it is built. For our research-based approach, the "research" is not just a label, but the foundation that shapes how water vulnerability is measured, how results are interpreted, and how insights are translated into practical decision support.

SUPPORTING RESEARCH

Redefining Water Scarcity Through the Integrated Water Strategic Resilience Index Amid Climate and Conflict Pressures

This paper develops the Integrated Water Strategic Resilience Index (IWSRI) and demonstrates why water resilience must be assessed through more than physical water availability. It integrates environmental, climatic, hydrological, governance, infrastructural, socio-economic and geopolitical considerations.

PRIMARY RESEARCH

Revolutionizing Hydro-Strategic Risk Assessment: Predictive Approaches and AI-Driven Systems with Hydro Nexus Analytics (HNA)

This paper presents Hydro Nexus Analytics (HNA), the analytical system underlying ÆGIR RESILIENCE's hydro-strategic assessments. It introduces the Overall Vulnerability Index (OVI), its four component sub-indices, the macro- and micro-level assessment structure, and the three connected outputs used to move from measurement to interpretation and advisory.

RESEARCH APPLICATIONS

Using real context to examine the methodology

The following examples are research applications and illustrative assessments discussed in the scientific work. They are not commercial client engagements.

RESEARCH APPLICATION

Marche Region

The HNA research uses the Marche region in Italy as a pilot assessment. The component analysis produced an Overall Vulnerability Index of 6, placing it within the intermediate range where continued monitoring and preventive measures are warranted.

RESEARCH APPLICATION

Chennai and Cape Town

The Chennai and Cape Town case studies demonstrates how prolonged drought, flooding, urban development, infrastructure dependency and governance can combine to bring major cities close to severe water disruption. The cases illustrate the limitations of waiting until reservoirs or supply systems are already under critical pressure

OVI

RESEARCH APPLICATION

Tamil Nadu

The HNA research applies the assessment structure retrospectively to Tamil Nadu following the 2019 water crisis. The analysis produced an Overall Vulnerability Index of 6.5, indicating continued structural vulnerability despite the end of the immediate emergency.

RESEARCH APPLICATION

MENA region

The IWSRI research applies a multidimensional resilience framework across the Middle East and North Africa, examining how water availability interacts with governance, infrastructure, socio-economic capacity, environmental conditions, and conflict-related pressure.
