Project 6 - The economics of chemical pollution risk management in UK Rivers (Paul Hudson, University of York)

About the project

About the Project This PhD project will pioneer a novel metric for river pollutants laying the groundwork for an economic framework that guides high-impact, cost-effective, risk management investments. Are you passionate about solving complex environmental challenges? Interested in creating non-toxic environments that benefit society and nature alike? This innovative and exciting PhD project, co-designed with non-academic partners, is part of the NERC-funded ECOSOLUTIONS Doctoral Focal Award, and offers the opportunity to address real world challenges with key opinion-formers to help support sustainable chemical development and create non-toxic urban & rural landscapes. Project details: Managing chemical pollution in river catchments requires knowing not just where exposure occurs, but where finite resources can deliver the greatest socio-economic impact. While existing models can identify intervention options to reduce chemical mixture risk and exposure, decision-makers lack a practical way to monetarily quantify these benefits under uncertainty. This PhD project addresses that challenge by developing a framework that helps to reduce the complexity of undertaking environmental decisions and identifying socially optimal interventions under uncertainty. We will do this by focusing the PhD on these three (indicative) overarching questions: 1) How can a standardized 'chemical mixture risk metric' be formulated with an acceptable degree of uncertainty? 2) How can this representative metric be operationalised within a Robust Decision-Making framework to quantify the value of interventions? 3) How can the above value-metric can be integrated within spatial models to determine a socially cost-effective portfolio of interventions? We will study this using the ECOMIX data (a high-resolution exposure model and dashboard) as a case-study for developing the metric through literature synthesis, modelling, and stakeholder-engagement as supported by decision-support methods (e.g., multi-criteria analysis). This PhD project will pioneer a novel metric for river pollutants laying the groundwork for an economic framework that guides high-impact, cost-effective, risk management investments. The ECOSOLUTIONS DFA Led by the Universities of Sheffield and York and the UK Centre for Ecology & Hydrology, ECOSOLUTIONS is a cutting-edge, transdisciplinary initiative. This innovative programme combines science, policy, and societal engagement to transform chemicals policy and management, enabling a safe, sustainable chemicals sector and non-toxic environments. This project is one of 19 projects that are available for the third ECOSOLUTIONS and final cohort who will work together to begin to understand and solve the problems of sustainable chemical design and use, as well tackling the problems that pollution causes in urban environments, rural landscapes and food systems. What You will Gain As an ECOSOLUTIONS PhD student, you will work with world-leading experts across diverse fields such as ecology, data science, digital solutions, chemistry, geography, psychology, environmental engineering, policy, and law. You will learn to tackle the risks posed by chemicals while enabling their societal benefits, adopting a whole-systems and solutions-focused approach. You will receive 3 years and 9 months of funding and take part in a dynamic training and development programme, including: Induction course: Connect with fellow students, supervisors, and the ECOSOLUTIONS team while exploring the programme’s mission. Primer course: Gain foundational knowledge on the environmental risks that chemicals pose, policy landscapes, and sustainable chemical innovation. Transferable skills workshops: Master data management, big data methods, research practices, communication, stakeholder engagement and more. Systems-solutions workshops: Collaborate across disciplines to explore sustainable chemical design and development, address pollution in urban & rural landscapes, and develop actionable solutions. Three-month secondment:UKWIR International conferences: Share your findings and network with global experts. The skills you will need To do this project you will need the following essential skills: Data analysis and/or modelling Social science methodologies (or willingness to learn) Ecotoxicology (or willingness to learn) Eligibility : To be considered for the ECOSOLUTIONS DFA, you will need at least an upper 2nd class honours degree or equivalent in a relevant discipline. As a collaboration of international research-led universities, we welcome students from all walks of life and from across the world. Within our programme, we are dedicated to diversifying our community. As part of our ongoing work to improve Equality, Diversity and Inclusion we strongly encourage applications from UK/Home candidates from identified underrepresented groups: Black, Asian and minority ethnic communities, those from a disadvantaged socio-economic background, and disabled people. Start Your Research Career with ECOSOLUTIONS: This PhD is part of the ECOSOLUTIONS Doctoral Focal Award (DFA), a prestigious NERC-funded program dedicated to training the next generation of environmental practitioners.
