Research is primarily focused in two areas:

1) the impact of climate change and rapid development on freshwater resources with a specific focus on groundwater and other natural stores of freshwater; and

2) the role of groundwater in improving access to safe water and food security.

1. climate change and groundwater (and other natural freshwater stores)

Current research is focused on the impact of elena_glacier_melt.jpgclimate variability and change on freshwater resources and water scarcity at basin scales. Improving the analysis of climate-related impacts on natural freshwater stores including principally groundwater but also soil moisture and ice, is a key component of on-going research. Although the use of models (analytical, statistical, numerical) plays a critical role in this research, a central aspect of this research is the use of observations, both ground-based and GRACE satellite measurements, as observations enable the development and testing of our conceptual understanding of the relationship between climate variability and change and terrestrial freshwater stores. This research contributes directly to international scientific programmes including UNESCO-GRAPHIC (Expert Advisory Panel) and IAH Commission on Groundwater and Climate Change (Co-Chair). Participation in these fora has led to the drafting of a cross-disciplinary policy brief for COP21 and establishment of The Chronicles Consortium to collate and analyse multi-decadal records of groundwater levels in Africa. Recently completed research includes: Groundwater resilience to climate change in Africa, policy brief - The Makutapora Record, QUEST-GSI: Global-scale impacts of climate change, Hydrological and climatological impacts of deglaciation in the Rwenzori Mountains of East Africa and projected changes in water resources in Uganda (e.g. Climate and Water in Uganda, Impact of climate change on the terrestrial hydrology of a humid, equatorial catchment in Uganda). Outcomes have been reported in Nature and The New York Times.

2. groundwater - food security & access to safe water

My research is also focused on the role of apachosp.jpggroundwater in enabling communities in low-income communities to adapt to the pressures of rapid development and climate variability. To date, research has focused primarily on the hydrogeology of weathered crystalline rock (saprolite-saprock) aquifer systems that underlie much of the tropics including 40% of sub-Saharan Africa and the entire Great Lakes Region of Africa (GLRA). More recently, research has been extended to include shallow alluvial aquifers in the Bengal Basin, the largest of the Asian Mega-Deltas. Research is both pragmatic - seeking to resolve the capacity of both aquifer systems to sustain groundwater abstraction for irrigation and urban water supplies - and fundamental (evolutionary hydrogeology) - seeking to understand how the long-term geomorphological evolution of aquifers in both environments determines their characteristics and interactions between groundwater and surface water:
Groundwater resilience to climate change in South Asia
GroFutures: Groundwater Futures in Sub-Saharan Africa
Shallow groundwater dynamics in the Bengal Basin and their implications for arsenic mobilisation and sustainable irrigation
Groundwater/surface water interactions on deeply weathered surfaces of low relief in the Upper Nile Basin of Uganda)
- ESPA: Enhancing Water for Food: poverty reduction through improved management of ecosystem services for sustainable food production in sub-Saharan Africa

Research Impact

My research addresses practical problems of securing and sustaining water supplies for domestic and agricultural needs in Sub-Saharan Africa and South Asia. Through direct engagement with stakeholders and decision makers together with long-term collaborations with research institutions, our research is designed to have an immediate and direct impact. Two areas where the impact of this research have been most pronounced are:

1) use of groundwater to adapt to climate variability and change as well as increased freshwater demand

Throughout Sub-Saharan Africa, groundwater now features centrally in national water development strategies, national irrigation plans, and regional initiatives to improve access to drinking water and food production through irrigation and thereby contribute to the UN Sustainable Development Goals. In addition, groundwater in Sub-Saharan Africa is currently the focus of a new £12-million research programme (UPGro) funded by the UK government to resolve the scientific basis for groundwater-based adaptations to climate variability and change as well as increased freshwater demand. The rationale for these plans and initiatives is rooted, in part, in collaborative research (e.g. Taylor and Howard, 1996; 2000; Taylor et al., 2009; 2010; 2013; Owor et al., 2009) and dissemination activities (e.g. Groundwater & Climate in Africa 2008 conference, IAH Commission on Groundwater & Climate Change) that I have led or been a collaborator (e.g. MacDonald et al., 2012). Our paper, "Quantitative maps of groundwater resources in Africa" is one of the most downloaded papers (>85,000 downloads) yet published by Environmental Research Letters, the leading open-access journal in environmental sciences. Featured on Al-Jazeera, this research has set a widely adopted benchmark for the quantification of groundwater resources in Africa. Recent collaborative research with the Ministry of Water in Tanzania (Taylor et al., 2013) directly informs the management of the Makutapora Wellfield which supplies freshwater to the national capital city, Dodoma. A summary of research outcomes related specifically to this collaborative research is available in both English and Kiswahili.

2) impact of global warming on alpine glaciers in East Africa

The relationship between global warming and the retreat of alpine glaciers in the Rwenzori Mountains of East Africa, first established by collaborative research that I led with the Ministry of Water and Environment (Uganda) and Makerere University (Taylor et al., 2006a; 2006b), is now a commonly cited illustration of the impact of climate change in East Africa. This research together with studies of the impact of glacial recession on alpine river flow (Taylor et al., 2009) informs not only Uganda's National Adaptation Plans of Action (NAPA) to combat climate change but also the management of both the Rwenzori Mountains National Park and local hydro-electric power generation stations. A summary of key research outcomes for stakeholders, policy makers, and decision makers is available in both English and LuKhonzo.
