OUR RESEARCH FOCUS
Climate Variability and Hydroclimatic Research
Water Resources Research and Environmental Sustainability
Climate Variability and Hydroclimatic Research
Africa is home to some of the world's most extensive semi-arid and climate-vulnerable regions, where increasing climate variability poses significant challenges to water security, ecosystem resilience, food production, and sustainable development. Recognizing these challenges, the African Institute of Excellent Research (AIER) is committed to advancing evidence-based climate research through the continuous analysis of long-term hydroclimatic datasets. By integrating meteorological observations, isotope hydrology, and geospatial technologies, we generate robust scientific evidence that supports climate adaptation, sustainable water resource management, and informed policy development across African ecosystems.
Our research aligns with the United Nations Sustainable Development Goals (SDGs), particularly SDG 6 (Clean Water and Sanitation), SDG 13 (Climate Action), SDG 15 (Life on Land), and SDG 17 (Partnerships for the Goals). Through interdisciplinary collaboration and scientific innovation, we develop data-driven strategies that strengthen the resilience of communities, safeguard natural ecosystems, and promote sustainable environmental management in the face of a changing climate.

UNESCO International Year of Quantum Science and Technology 2025: A review
The United Nations Educational, Scientific and Cultural Organization (UNESCO) designated 2025 as the International Year of Quantum Science and Technology (IYQ 2025) to commemorate the centenary of the development of quantum mechanics. This global initiative celebrated a century of scientific discovery while promoting international collaboration, education, and innovation in quantum science and its applications for sustainable development.
Quantum science investigates the behaviour of matter and energy at the atomic and subatomic scales. Building on these principles, quantum technologies including quantum computing, quantum sensing, and quantum communication offer unprecedented computational capabilities that have the potential to transform research across numerous disciplines. Unlike classical computers, which process information using binary bits, quantum computers use quantum bits (qubits), enabling them to solve certain complex problems far more efficiently than conventional computing systems.
The application of quantum technologies presents significant opportunities for advancing water resources research and management. Quantum computing and quantum sensing can enhance the analysis of large and complex datasets generated from remote sensing platforms, environmental sensors, and satellite observations, leading to more accurate assessments of water quality, groundwater systems, and hydrological processes. These advancements directly support Sustainable Development Goal (SDG) 6, which seeks to ensure the availability and sustainable management of water and sanitation for all.
Recent studies have demonstrated the potential of quantum-enhanced machine learning techniques, including quantum support vector machines and quantum neural networks, for predicting water quality. For example, research conducted in the Umgeni Catchment in Durban, South Africa, applied these methods to evaluate water quality based on physicochemical and microbial parameters. The findings indicated improved predictive performance, particularly when polynomial and radial basis function kernels were employed, demonstrating the ability of quantum-inspired algorithms to address complex environmental datasets.
Beyond quantum computing, Geographic Information Systems (GIS) remain indispensable for environmental and hydrogeological investigations. Open-source platforms such as QGIS provide flexible and customizable tools for integrating geospatial data, supporting environmental modelling, and informing evidence-based decision-making. Although QGIS itself is not a quantum technology, it complements quantum-enabled analytical approaches by providing a robust framework for spatial data visualization and interpretation.
In support of the objectives of the International Year of Quantum Science and Technology, the African Institute of Excellent Research (AIER) intends to integrate advanced geospatial and computational technologies, using Quantum into hydrogeological investigations in the Volta Region of Ghana, subject to funding support from MISA Energy. The proposed research will assess the potential influence of fuel stations on groundwater quality through advanced subsurface investigations and environmental modelling. The outcomes are expected to contribute to the development of a comprehensive geological model that will strengthen evidence-based groundwater management and support sustainable environmental policy and decision-making across Africa.

Comparative Study of DRASTIC-LU and Radioactive Isotope Approaches for Assessing Groundwater Vulnerability to Pollution: A Case Study of Abuja, North-Central Nigeria
As urbanization continues to accelerate across Nigeria's capital city, protecting groundwater resources has become increasingly critical. A study led by Dr. Mary Etuk, Lead Researcher and Co-founder of the African Institute of Excellent Research (AIER), provides new insights into how groundwater vulnerability can be assessed more effectively to support sustainable water resource management.
Groundwater in Abuja is increasingly threatened by pollution arising from rapid urban expansion and other human activities. Although several methods are available for assessing groundwater vulnerability, selecting the most appropriate approach for a particular hydrogeological setting remains a major challenge. Recognizing this, the study compared two internationally recognized assessment methods, the DRASTIC-LU model and the tritium radioactive isotope tracer technique, to evaluate their performance within the Abuja aquifer system.
The DRASTIC-LU assessment identified the southwestern and northeastern parts of Abuja as areas of high to very high groundwater vulnerability (Figure 1). To validate these findings, the researchers compared the vulnerability map with groundwater quality data. The results showed that 33% of sampled wells exceeded the recommended nitrate limits for drinking water, while 87% of these contaminated wells were located within areas classified as highly to very highly vulnerable, demonstrating the model's strong predictive capability.
The tritium radioactive isotope approach complemented these findings by providing valuable information on groundwater recharge history across the aquifer. The technique distinguished between recent recharge (post-nuclear era) and older recharge (pre-nuclear era), enabling the identification of areas dominated by preferential flow, which are more susceptible to contamination, and diffuse flow, which generally exhibit lower vulnerability.
Using the Origin–Pathway–Target (OPT) conceptual framework, the study systematically evaluated the strengths and limitations of both approaches. While the DRASTIC-LU model effectively maps spatial vulnerability based on hydrogeological
characteristics, the isotope tracer approach provides direct evidence of groundwater movement and recharge processes that influence contamination risk.
The study concludes that combining the DRASTIC-LU model with radioactive isotope techniques provides a more comprehensive and reliable framework for groundwater vulnerability assessment than either method alone. This integrated approach offers a stronger scientific basis for groundwater protection, particularly in rapidly urbanizing regions where water resources are under increasing pressure.
Why This Research Matters
Reliable groundwater vulnerability assessments are fundamental to protecting drinking water supplies, guiding land-use planning, and preventing groundwater contamination before it occurs. By demonstrating the value of integrating conventional hydrogeological models with isotope hydrology, this research provides policymakers, water resource managers, and environmental regulators with a more robust framework for evidence-based decision-making. The findings underscore the importance of adopting multidisciplinary approaches to ensure the long-term sustainability and resilience of groundwater resources in Nigeria and across Africa.
