Valerie Nelson is Professor of Sustainability and Political Ecology and leads the Centre for Society, Environment and Development. Her work is grounded in decolonial, relational and more‑than‑human approaches to sustainability, challenging extractivist, technocratic and growth‑centric paradigms. She works with political ecology as a practice of critique and care, centring questions of power, justice, land, responsibility and the conditions for collective flourishing across human and more‑than‑human worlds.
She holds a first degree in Social Anthropology (University of Cambridge), an MSc in Rural Resources and Environmental Policy (Wye College, University of London), and a PhD entitled Global Supply Chain Sustainability Initiatives: Impacts, Governance, Systemic Constraints and Regenerative Alternatives (University of Greenwich). She currently co‑leads the Political Ecology, Culture and Arts Research Group at NRI. The group’s work is explicitly committed to pluriversal futures and explores relationality and the more‑than‑human; Indigenous and local ontologies; socionatures and biodiversity; land, territory and ecojustice; the politics and meanings of food and farming; transformative change and social movements; post‑growth economies, commoning and repair; environmental intersectionalities; and ethics of care that exceed the human.
Valerie’s research has long worked with participatory methods, developing participatory, creative methods such as participatory video and farmer-to-farmer learning in the 1990s and has continued with a series of farmer, community-based and multi-actor social learning processes. She increasingly engages arts‑based methods and collaborations as decolonial practices of inquiry to explore justice and futures. These approaches aim to unsettle dominant narratives, open space for marginalised and Indigenous ways of knowing, and support collective imagination of otherwise worlds. Current research centres upon more-than-human and relational approaches, and trans-hegemonic approaches to transformative change.
She has worked in international development and environmental research since 1992. Her early work in Belize focused on community engagement in forest planning and management, undertaking long‑term, situated research with Mayan and migrant communities. This was followed by research at an agricultural research institute of the University of the State of Mexico, working with Mazahua Indigenous Peoples in the central highlands to understand agrarian lifeways, territorial relations and knowledge systems embedded in land and practice.
Following a period supporting transnational partnerships between protected areas in Europe, Latin America and Asia, she joined Oxfam GB’s Policy Department, contributing to the South–South Environment Learning Programme. Since joining NRI in 1996, Valerie has developed a sustained body of critical, interpretive, participatory and transdisciplinary research spanning food politics and governance, agroecology, land rights, climate change adaptation, rural development, and latterly biodiversity, human-nature relations and sustainability transformations. Her work brings together political ecology, critical geography, anthropology and Indigenous‑informed epistemologies, and is grounded in collaboration with diverse social and other-than human communities and social movements in Latin America, Sub‑Saharan Africa, Asia and the UK.
She has led major research and action‑learning programmes (EU Horizon, FCDO, ESRC funded), including on diverse topics including: participatory rural development; socio‑ecological approaches to livelihoods and food systems; gendered and intersectional climate adaptation; smallholder agricultural resilience; land rights and territorial governance; agroecology and alternative food networks; and critical analyses of fair trade, sustainability standards and global value chains. She has explored post‑growth, regenerative and commons‑based economies, and transformative change from Indigenous, feminist and more‑than‑human perspectives.
Valerie is an expert contributor to the Intergovernmental Science–Policy Platform on Biodiversity and Ecosystem Services (IPBES). She was a contributing author to the Values Assessment (2022), a Scoping expert in the Business and Biodiversity Scoping Study (2022) and was a Lead Author for the Transformative Change Assessment (2024), in which she addressed colonial modernity, relational, More-than-Human and Indigenous ontologies. She actively supports IPBES Indigenous and Local Knowledge dialogues. She was a Lead Author for the UNEP Global Environment Outlook GEO‑7 State of the Environment Report (2025) and served on the GEO‑7 Indigenous and Local Knowledge Taskforce. She is a Coordinating Lead Author for the Options for Action chapter of the ongoing IPBES Second Global Biodiversity Assessment.
Her policy‑engaged work includes serving on the Scottish Government’s Environment Strategy Advisory Panel on international impacts (2023) and leading research on transformative change which has informed the first ever Strategy (2026). She is a member of Natural England’s Nature Futures Advisory Group and is engaging with Natural England and other nature agencies on transformative change. She is also part of the Friends of the International Land Coalition, aligning with global struggles for land justice and Indigenous territorial rights. Previously, she served for six years on the UK and Ireland Development Studies Association Council, co‑leading the Climate and Development Study Group and convening critical political ecology panels. Valerie is also an experienced evaluation and learning specialist, leading complex, multi‑country evaluations grounded in reflexivity, participation and power awareness. She has undertaken high‑level consultancies for organisations including the International Land Coalition, UNDP, the European Commission, Irish Aid, FCDO, the Dutch Government, ISEAL, ILO, Defra, BEIS, CGIAR, Oxfam, Fairtrade International, the Fairtrade Foundation, Rainforest Alliance and others.
She is a Section Editor for PLOS: Sustainability and Transformation and a co‑editor of Global Social Challenges.
Valerie has contributed to the establishment of new research fields, most notably gender and climate change beginning in the early 1990s and subsequently, and the impact, governance and power relations in agro-food systems, including critical analysis of hybrid governance and its limitations and governmentality, such as reform-oriented approaches (e.g. corporate codes, sustainability standards, due diligence, sector transformation). She has explored alternative food networks and agroecology movements and practices and developed new participatory, action research and transdisciplinary methodologies, e.g. pioneering participatory video in Malawi (1996-98), farmer and stakeholder climate future learning journeys in Tanzania (2010s), farmer field school evaluation in Malawi and transdisciplinary multi-stakeholder and civic engagement in learning cycles.
Valerie currently leads the Political Ecology, Culture and Arts (PEAC) Research Group at the NRI (ADD URL), which has the following research themes:
- Relationality and sustainability
- The more-than-human, socionatures and biodiversity
- Politics and meanings of food and farming
- Ecojustice, power and land
- Transformative change, social movements and sustainability futures.
- Post-growth economies and communing.
- Environmental intersectionalities and ethics of care.
Her current work focuses upon the following: relational philosophies and sustainability; critical analysis and action research on imaginaries, socionatures and human-nature relations; colonial modernities, pluriversal conviviality and transformative change; biodiversity and equity in telecoupled agrofood system contexts; Indigenous land rights and futures; arts-based methods and speculative futuring.
Transformative Change in telecoupled agrofood systems for biodiversity and equity (EU Horizon, 2023-26)
Partnering with Wageningen University, Netherlands, University of the Andes, Colombia, University of Dschang, Cameroon, the University of Kabianga, Kenya, IDDRI and CIRAD, France, and Hanken University, Finland. The project explores transformative pathways in agro-food systems, moving beyond reform-oriented market-based mechanisms to explore more radical regenerative alternatives. Includes research on rural imaginaries, the more-than-human, emotional ecologies, and issues of biodiversity, equity and justice, within landscapes linked to EU consumption and biodiversity, analysis of transformative change pathways, leverage points and levers e.g. rights of nature, social movements, collective action and commoning for transformative change, as well as facilitating social learning cycles at landscape, national, EU and global scales.

Social learning for people-centred land governance
Social learning for LandCollaborative, a Global Community of Practice involving social learning cycles and co-production of learning outputs for the LandCollaborative (International Land Coalition, Mekong Delta Rural Land Governance Programme and WeltHunger Hilfe (WHH) LandforLife programme). The project involved working with 27 organisations in 13 national civil society platforms working on land rights and governance.
Critical analysis and assessment of fair trade and sustainability market-based mechanisms and responsible business approaches.
Multiple studies on fair and ethical trade schemes, sustainability standards and certification impacts, social impacts of corporate codes of practice, sector transformation and sustainable landscape approaches, responsible business and ethical trade schemes, trade and global value chains social and economic upgrading innovations, and sustainable finance for diverse donors and research councils (FCDO, ILO, Fairtrade International, Fairtrade Foundation, Max Havelaar, ISEAL, Better Cotton Initiative, Rainforest Alliance, Dutch government). This work led the way asking questions about the effectiveness, impact, politics and governance of private standards and alternative, solidarity trade schemes and initiatives. It generated extensive evidence on impacts, research on the politics and ethics of value chain sustainability governance, and highlighted the inherent limitations and problems associated with market-based mechanisms for sustainability and transformative change. Recent studies on human rights, environmental due diligence and rights of nature.
Politics and governance implications of private standards initiatives in Kenyan agri-food chains (2008-2011)
With the Universities of Leeds and Nairobi (ESRC-DFID). This research explored actor struggles over value chain sustainability governance and the emerging role of private actors in shaping narratives and practices. Looking beyond the vertical, the research explored the embedded nature of global value chains and the power inequalities infused in such agrofood chains, the contingent nature of smallholder and worker agency and participation, and the governmentality of sustainability standards and codes. The control-oriented nature of ethical governance was identified as well as areas of resistance and alternative economy narratives.
Transdisciplinarity and participatory learning approaches in sustainable agriculture and agroecology
Over several decades including pioneering work on participatory video to support community enquiry, communication and advocacy on livelihoods and the environment in Malawi (1996-98, DFID funded), Farms of the Future project involving facilitation of farmer and agriculture stakeholder learning journeys on climate adaptation in Ghana, Burkina Faso and Tanzania (CCAFS, 2011-13), National Learning Alliances using multi-stakeholder social learning cycles on sustainable agriculture in Tanzania, Malawi, Zambia, Ghana and Ethiopia (DFID SAIRLA programme), and participatory farming learning including video documentation in evaluative learning on FAO Strengthening Climate Resilience Programme (EC Global Climate Change Alliance, Malawi, 2015-19). Recent study for Agrinatura on Agroecology and Value Chains with FIBL.

Social learning for LandCollaborative, a Global Community of Practice involving social learning cycles and co-production of learning outputs for the LandCollaborative (International Land Coalition, Mekong Delta Rural Land Governance Programme and WeltHunger Hilfe (WHH) LandforLife programme). The project involved working with 27 organisations in 13 national civil society platforms working on land rights and governance.
Critical analysis and assessment of fair trade and sustainability market-based mechanisms and responsible business approaches.
Multiple studies on fair and ethical trade schemes, sustainability standards and certification impacts, social impacts of corporate codes of practice, sector transformation and sustainable landscape approaches, responsible business and ethical trade schemes, trade and global value chains social and economic upgrading innovations, and sustainable finance for diverse donors and research councils (FCDO, ILO, Fairtrade International, Fairtrade Foundation, Max Havelaar, ISEAL, Better Cotton Initiative, Rainforest Alliance, Dutch government). This work led the way asking questions about the effectiveness, impact, politics and governance of private standards and alternative, solidarity trade schemes and initiatives. It generated extensive evidence on impacts, research on the politics and ethics of value chain sustainability governance, and highlighted the inherent limitations and problems associated with market-based mechanisms for sustainability and transformative change. Recent studies on human rights, environmental due diligence and rights of nature.
Politics and governance implications of private standards initiatives in Kenyan agri-food chains (2008-2011)
With the Universities of Leeds and Nairobi (ESRC-DFID). This research explored actor struggles over value chain sustainability governance and the emerging role of private actors in shaping narratives and practices. Looking beyond the vertical, the research explored the embedded nature of global value chains and the power inequalities infused in such agrofood chains, the contingent nature of smallholder and worker agency and participation, and the governmentality of sustainability standards and codes. The control-oriented nature of ethical governance was identified as well as areas of resistance and alternative economy narratives.
Transdisciplinarity and participatory learning approaches in sustainable agriculture and agroecology
Over several decades including pioneering work on participatory video to support community enquiry, communication and advocacy on livelihoods and the environment in Malawi (1996-98, DFID funded), Farms of the Future project involving facilitation of farmer and agriculture stakeholder learning journeys on climate adaptation in Ghana, Burkina Faso and Tanzania (CCAFS, 2011-13), National Learning Alliances using multi-stakeholder social learning cycles on sustainable agriculture in Tanzania, Malawi, Zambia, Ghana and Ethiopia (DFID SAIRLA programme), and participatory farming learning including video documentation in evaluative learning on FAO Strengthening Climate Resilience Programme (EC Global Climate Change Alliance, Malawi, 2015-19). Recent study for Agrinatura on Agroecology and Value Chains with FIBL.
