My research focuses on human-environment relationships, particularly:
I take an interdisciplinary approach, grounded in systems thinking, using theories and both qualitative and quantitative methods from the natural and social sciences. A systems focus helps my work to develop solutions to specific problems while recognising the complexity of the world's sustainable development challenges and the trade-offs and opportunities created by change. My research projects commonly involve big interdisciplinary teams that bring together researchers from around the world, from disciplines such as geography, ecology, biology, economics development studies, politics, business and management, international relations, agricultural sciences and engineering. My work is published in a range of world-
leading journals across multiple fields (see Google Scholar profile for details)
Despite the different development contexts around the world, many of the challenges and the underlying root causes of change are similar across continents.
Most of my field work is in the Global South. I have worked and travelled in Africa, Asia-Pacific, Europe and the Americas, visiting more than 120 countries and collecting their flags along the way. My work is anchored in strong partnerships with in-country researchers at local universities, international institutions and NGOs. I involve MSc and PhD students from my study areas as research assistants and translators, helping to build their capacity and skills. I also participated in the inaugural Homeward Bound Project women in science leadership programme which took me to Antarctica in December 2016.
In 2017, I won a Wolfson Merit Award from the Royal Society, and in 2013, was awarded a Philip Leverhulme Prize for my work on environmental change and sustainable development in drylands. In 2015 I was presented with a Women of Achievement Award while working at the University of Leeds.
I am motivated by making a difference through my work, and to do this I build strong
relationships with research users across levels, from the local to the international. At an international level, my research has informed policy interventions through e.g. the United Nations Convention to Combat Desertification (UNCCD). I was a Coordinating Lead Author for the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) Regional Assessment for Africa (2018), as well as Lead Author for the IPBES Land Degradation and Restoration Assessment (2018), and a member of the IPBES Expert Group on Policy Support Tools and Methodologies. I was a Lead Author on the Intergovernmental Panel on Climate Change (IPCC) special report on Climate Change and Land (2019) and for the IPCC's 6th Assessment Report, where I was responsible for sections of chapter 8 on Poverty, Livelihoods and Sustainable Development, and co-led Cross-Chapter Paper 3 on Deserts, Desertification and Semi-arid Areas.
I am a member of the Economics of Land Degradation (ELD) Initiative Working Group and have led capacity building activities on the costs and benefits of different land management options in locations including Botswana, India, Kenya, Rwanda and Somalia. I chaired the Independent Task Force of the CGIAR’s Research Programme on Dryland Systems, which was commissioned to develop a “global research in development programme” to achieve sustainable livelihoods for dryland populations that depend on agriculture, as well as co- chairing the T7 task force on Climate and Environment. T7 was established by the G7 and in 2022 was mandated by the G7 chair (Germany) to bring together leading research institutes and think tanks across the G7 countries to develop research-based policy proposals to inform discussions in the Germany G7 summit (June 2022).
I currently sit on the International Scientific Advisory Board of the Centre for Dryland
Agriculture at Bayero University Kano, Nigeria, one of the Africa Centres of Excellence
supported by the World Bank, as well as being on the International Advisory Board for Centro de Estudos do Ambiente e do Mar (Centre for Environmental and Marine Sciences), Universidade de Aveiro, Portugal. I am also on the Advisory Board on Climate Change for the University of Graz, Austria.
I hold a BSc in Physical Geography (2000), an MSc in Environmental Monitoring and
Assessment in Drylands (2001), and a PhD in Geography (2005), all from the University of Sheffield, UK. I completed a teaching award qualification (2009) and am a Fellow of the Higher Education Academy.
I previously worked at the University of Leeds (2007-2020) where I was co-Director and then Director of the Sustainability Research Institute from 2011-2014. Prior to my post at Leeds, I worked at the University of Manchester at what was then the Institute for Development Policy and Management, and the University of Sheffield in the Department of Geography.
I have supervised 35 PhD students to successful completion and mentored 28
postdocs/fellows. I was a Senior Scientific Mentor on the GIZ Young Professionals
Programme on Soils and Sustainable Land Management (2015-2017), and mentored an IPBES Young Fellow via the IPBES Africa Regional Assessment, as well as being a mentor for early career researchers for the Association of Commonwealth Universities Climate Change Cohort in the lead up to COP26.
Memberships
I sit on grant selection panels for several UK research funders and am an international peer reviewer for funders in Europe, North America, Australasia and Africa, including the UK research councils, Royal Society, Wellcome Trust, US National Science Foundation, European Research Council, Swiss National Science Foundation, International Foundation for Science (Sweden), Marsden Fund, New Zealand Ministry for Science and Innovation, Georgia National Science Foundation, Swedish Environmental Protection Agency, National Geographic, Slovenian Research Council and others. I was reviewer for the ESRC-AHRC international benchmark review of British Human Geography (2012) and have sat on external appointment committees for several Universities in the UK, Switzerland, Sweden and Ireland.
I am a reviewer for 50 ISI listed journals, and in the past, held journal editorial board
positions for Resources (MDPI), Food Security and Land Degradation and Development. I am currently an editorial board member for the Royal Society’s journal Philosophical Transactions of the Royal Society.
I have undertaken various media and outreach activities, e.g. interviews as a scientific expert for BBC TV, Carbon Brief, ITV, Kent Messenger, BBC Radio, Japan Times, Canada Mail and Guardian, Reuters and Scidev.net.
I regularly co-organise sessions at major scientific meetings e.g. the EGU (2025, 2014), Resilience Conference (2014) and Ecosystem Services Partnership Africa conference (2019); policy events e.g. UNCCD Scientific Conferences (2013, 2015, 2024), UNCCD Science Day (2019); and have given invited seminars in both the UK and overseas, as well as keynotes at prestigious meetings, e.g. Royal Society Theo Murphy meeting (2019); FAO Global Soil Erosion symposium (2019).
I have externally examined 26 PhD theses in both the UK and overseas, one DSc thesis, and examined taught MSc programmes at University of Reading, and BA/BSc programmes at University of East Anglia.
At the University of York, I am the Director of the York Environmental Sustainability Institute, and Associate Director of the Leverhulme Centre for Anthropocene Biodiversity (LCAB), and a member of the Interdisciplinary Global Development Centre (IGDC). I also sit on the Environmental Sustainability At York (ESAY) leadership team and the Sustainability Steering Group.
