About the Project

Our hypothesis is that the hazards posed by contaminated lands/soils are worsening due to climate change. Extreme precipitation events (both, intensity and frequency) are causing moisture regime change in hydrological catchments, which is rendering pollutants in contaminated soils to become (physically, chemically and biologically) mobile with rising bioavailability in various land-types and -uses such as agricultural/farm lands. This increased mobility may even generate new contaminated sites e.g. via floods and rising water levels. This climate change induced escalating mobility can lead to additional problems for human health and the environment – comprising hydrosphere, lithosphere atmosphere and the biosphere.

 Specifically, there is a substantial lack of knowledge on how moisture regime changes (i.e. varying saturation levels) in various soil types can influence mobility and bioavailability of pollutants (particularly metal(oid)s) in contaminated catchments. Based on Climate Change projections (e.g. from IPCC – Intergovernmental Panel for Climate Change), the proposed PhD will focus on this multi-faceted knowledge gap by imitating such conditions in laboratory- and field-based experiments. Metal contaminated farmlands in north-east region of England would be employed as real-world case-studies and empirical surveys (including both quantitative and qualitative, questionnaire and semi-structured interviews) with landowners, and experts in contaminated land/soil risk assessment and climate change. In addition, a key outcome of the research will be to frame a protocol/system of how such climate change induced additional risks can be and should be measured and mitigated, so that the environment as a whole can be rendered more resilient via adapting around the climate change impacts.

 The proposed PhD, being multi- and inter-disciplinary by virtue of its nature, offers research training on a wide range of methodologies. The PhD links to a number of NERC programmes: UK Climate Resilience; Flooding from Intense Rainfall; Emerging Risks of Chemicals in the Environment; Earth System Modelling Strategy (ESM); and Building Resilience to Environmental Hazards (both Natural and Anthropogenic).

The PhD candidate will be involved in lively networks both within and beyond NERC, within and beyond UK, thereby inducing internationalisation to the research.


Funding Notes

This project is part of the NERC ONE Planet DTP. Each of our studentship awards include 3.5 years of fees (Home/EU), an annual living allowance (£15,650) and a Research Training Support Grant (for travel, consumables, etc).
Home and International applicants (inc. EU) are welcome to apply. Following the UKRI announcement regarding their new 30% UKRI international recruitment policy (to take effect from September 2021) both Newcastle University, and Northumbria University, have agreed to pay the international fee difference for all International applicants (inc. EU) who are awarded a DTP studentship. Interviews will take place in February 2022.
