Julia has an interdisciplinary background in environmental sciences and economics, with an emphasis on environmental valuation and qualitative and participatory approaches and a focus on water research. Graduated as Doctor in the University of Cordoba (Spain), Julia joined the Sustainability Research Insitute in July 2015, after 5 years as Senior Researcher at The James Hutton Institute in Scotland. Previously, she had worked for the Basque Centre for Climate Change (Spain) and was a guest researcher at the Institute for Environmental Studies (IVM) of the VU University in Amsterdam (The Netherlands).

Julia is Asociate Director of water@leeds, one of the largest interdisciplinary centres for water research in any university in the world, encompassing expertise from across the physical, biological, chemical, social and economic sciences and engineering as well as the arts; and to the Water, Environmental, Agricultural and Resource Economics (WEARE) research group of the University of Cordoba (Spain). Julia is member of the Steering Committee of the Scottish Government’s Centre for Expertise in Waters, the Swedish Research Council Panel on General Governance and Sustainability and the UK’s Natural Environment Research Council Peer Review College. She is Academic Editor of the journal PLOSOne.

Julia is author of 59 ISI-indexed publications and >46 other peer reviewed publications, including the first monograph on water ecosystem services, Water Ecosystem Services: A Global Perspective published by Cambridge University Press.

Julia is also member of the Editorial Board of the Spanish Journal of Agricultural and Resource Economics.

Research Interests

Julia’s research focuses on the relationships between society and water systems, and has a strong interdisciplinary and policy-relevance emphasis. Three main research lines guide Julia’s work:

  1. How to assess the impacts of changes in water systems on human welfare. Julia looks at the multiple values of water ecosystem services and how they can be assessed. This includes working with natural scientists to translate their understanding of biophysical processes and modelling results in terms of service delivery for the design of valuation research.
  2. How economic tools and principles can best be applied to attain sustainable water management. Julia looks to integrate outputs of hydrological modelling and stakeholder knowledge into the economic analysis of water management. Her work in this area has mostly taken place in the context of the European Water Framework Directive and in relation to Payments for Ecosystem Services in Latin America.
  3. How changes in the provision of ecosystem services compromise the capacity of communities to use and enjoy them and how communities adapt to these changes. This includes previous work on the economics of droughts and adaptation to climate change, and current work on ecosystem services-based approaches and community-based management of natural resources and scenario planning in Latin America and Africa.

Julia’s current and recent research projects include:

  • Capture, recycling and societal management of phosphorus in the environment (ReCAP)
  • Yorkshire Integrated Catchment Solutions Programme (iCASP) – ~ £6million funded by NERC (2017 – 2022). Julia leads the socio-economic work and impact evaluation of iCASP.
  • Securing biodiversity, functional integrity and ecosystem services in DRYing riVER networks
  • Contract solutions for delivery of agri-environmental-climate public goods by EU agriculture (CONSOLE) – €5million funded by EU (2019-2022). Julia leads the economic valuation work of the UK case study.
  • The role of Phosphorous in the Resilience and Sustainability of the UK food system – £1.51M funded by BBSRC, ESRC, NERC and the Scottish government (2018 – 2021). Julia leads the socio-economomic strand.
  • Activating change on environmental governance through performance-based methods (PerformingChange) – £15k funded by ESRC Impact Accelaration Account (2019-2020). Principal Investigator.
  • Economic benefits of peatland restoration: making the numbers count for policy in collaboration with The James Hutton Institute and the Scottish Rural Collague – funded by ESRC’s Impact Acceleration Account (2016 – 2017).
  • European Trainning and Research Network for environmental flow management (EuroFlow) ~€4M funded by the EU Marie Curie Actions for Innovative Training Networks (H2020) (2017 -2020).
  • Understanding ecosystem stocks and tipping points in UK peatlands – ~£400k funded by NERC’s Valuing Nature Programme (2016 – 2018). Julia co-leads the workpackage on socio-economic impacts.
  • Understanding people’s values and preferences of peatland restoration: a national level assessemt for Scotland in collaboration with The James Hutton Institute and the Scottish Rural Collague – funded by the Scottish Goverment (2012 – 2017).
  • Applying ecosystem services-based approaches to water resource decision making: studying the risk of nature commodification in Mexico’s last free-flowing river in colaboration with ECOSUR in Mexico- £75k funded by the British Council Newton Fund Advanced Fellowship (2016- 2018). Principal Investigator.
  • UR in Mexico- funded by the British Council Newton Fund Advanced Fellowship (2016- 2018).
  • Exploring the potential for setting up a Payments for Ecosystem Services (PES) scheme in Ethiopia in collaboration with AECOM, Kings College London and the University of Addis Ababa – funded by the Global Green Growth Institute (2016).

Teaching Interests

Julia currently manages the undergratduate Sustainability Economics module and the postgraduate Research Methods module at SRI.

She has designed and facilitated several training courses on environmental economics and water management in Spain, Peru and the Dominican Republic.

She currently supervises two PhD students: Christopher Schulz, whose thesis aims to explore new strategies to incorporate non-monetary values of water resources into policy making and water governance and focuse on the Brazilian Pantanal; and Blandine Boef who is undertaking a critical study of cost-benefit analysis in the EU water framework directive planning in France and the UK.

She is also generally interested in producing communication and pedagogic materials explaining complex concepts to broader audiences, like this 3 minutes clip explaining Payments for Ecosystem Services (A version in Spanish and in Mandarin also available):


Julia is author of 59 ISI-indexed publications and >46 other peer reviewed publications, including the multi-authored book Water Ecosystem Services: A Global Perspective by Cambridge University Press, that she has coordinated (Martin-Ortega et al. 2015). She is also author of a number of knowledge exchange outputs addressed to non-academic audiences.
