• Current PhD researchers

Adam Cross

Supervisors: Dr Joanna Allan, Prof Katy Jenkins and Dr Inge Boudewijn

PhD research summary: Adam’s PhD research investigates the resistance practices of women land and environmental defenders in Colombia who are affected by forced displacement. His project focuses on how displacement driven by armed conflict, dispossession and ecological destruction provokes experiences of dislocation and loss, but also creates spaces within which new relationships with community, territory, and place are generated. Adam’s research uses decolonial and feminist perspectives to analyse the diverse knowledges and resistance practices which emerge from contexts shaped by patriarchy, racism, and intersecting histories of colonialism and development.

Ana Camila Ribeiro Moreira (Visiting PhD Researcher)

Supervisors: Dr Ana Laura Zavala Guillen (Northumbria University, UK) and Dr Candice Vidal e Souza (Pontifícia Universidade Católica de Minas Gerais - PUC-MG, Brazil)

PhD working title: Transnationalisation of the Maroon communities’ struggles in Alcântara, Brazil

PhD research summary:  Since the 1980s, the Brazilian state has systematically displaced Maroon ('Quilombola') communities in Alcântara, Northeast Brazil, in order to construct and expand the Alcântara Space Centre, a rocket launch site. The remaining communities have constantly been threatened by the military. In response to years of oppression, the Maroons formally submitted their case to the Inter-American Commission on Human Rights (IACHR) in 2001. They also appealed to the International Labour Organisation (ILO) in 2008. Ultimately, in April 2023, Brazil was found guilty of violating the human rights of Alcântara’s Maroon communities by the Inter-American Court of Human Rights. Consequently, Brazil officially apologised to the ethnic groups and recognised their collective land rights. This study therefore aims to analyse the transnationalisation of the ‘Quilombolas’ struggle in Alcântara, emphasising their networks with the human rights mechanisms of the IACHR and ITO.

Aneeta Shajan

Supervisors: Prof Steve Taylor and Prof Katy Jenkins

PhD research summary: Aneeta's PhD research looks at return migration from Gulf economic region to Kerala, India. The research aims to conceptualise the impact of migration on the health outcomes of migrants in the Kerala‐Gulf corridor. The effect is analysed by examining if and how temporary international migration has brought about accelerated health vulnerabilities amongst migrants compared to non‐migrants from the same origin area. It does so by navigating how migration has led to better opportunities, income, lifestyle, and quality of life and how these factors have affected the health‐seeking behaviours of migrants in the destination country.

Angelica Ribichini

Supervisors: Dr Oliver Hensengerth, Prof Matt Baillie Smith and Dr Joanna Allan

PhD research summary: Through an intersectional feminist lens, Angelica's research explores youth vulnerability and adaptive capacity to climate change in the Vietnamese Mekong Delta - a region that is widely considered to be one of the most exposed to the impacts of climate change globally. Employing a participatory action research (PAR) methodology, the project seeks to illuminate how intersecting markers of power and inequality shape young people's experience of, and ability to cope with, changing living conditions in the delta area.

Benita Siloko 

Supervisors: Dr Oliver Hensengerth and Prof Helena Farrand Carrapico

PhD working title: Human security, livelihoods and environmental degradation in the Niger Delta Region, Nigeria

PhD research summary: Benita’s PhD research seeks to understand and address the complex connection between vulnerability, human security, and livelihoods in the context of environmental degradation, in the Niger Delta region, Nigeria. Understanding the factors that shape or contributes to social vulnerabilities of the Niger Delta or a community is important, as this will inform the needed entry points to increase resilience. The environment is humans first right, without a safe environment, we cannot exist to claim other rights – be it social, political, or economic rights. Benita’s research further brings together the concept of environmental security, justice and emancipation and the rights-based approach to human security.

Bina Limbu

Supervisors: Dr Katie Oven and Dr Sarah Hughes

PhD working title: Living with mountain hazards: Everyday experiences of rural households in Nepal

PhD research summary: Owner-driven approaches to disaster risk reduction (DRR) have been globally endorsed under the Sendai Framework 2015-2030, however, much ambiguity exists regarding how to effectively integrate community participation and local knowledge into DRR practices. The current literatures contrastingly portray disaster-affected people either as ‘suffering victims’ driven to risky locations, or as the ‘drivers of their own change’ possessing indigenous knowledge and social capital. However, in the messiness of everyday reality, householders constantly negotiate with state and non-state bodies to rebuild their lives and livelihoods, but do they end up any more resilient than before? This research aims to seek answers by carrying out ethnographic study of people living in geo-hazardous locations in Dhading district of Nepal (prone to landslides, floods and earthquakes). In doing so, this study explores what kind of socio-economic, political, and environmental factors interplay in their everyday lives and how these shape their agency and decisions-making regarding hazards.

Daniel Walsh

Supervisors: Dr Pete Howson and Dr Paul Dolan

PhD research summary: McKinsey forecasted that the space economy will be worth $1.8 trillion by 2035, highlighting the expanding commercialisation of outer space. The crux of the expanding space economy is the launch vehicle (i.e. rocket) without which the space economy could not function. Little is known about the ‘production networks’ of launch vehicles and how these are enmeshed within the economic development of specific locations. Building on an emergent body of scholarship in ‘geographies of outer space’, Daniel’s PhD research seeks to investigate how the production networks of launch vehicles influences economic development in the United States, particularly New Mexico and the ‘Gulf South’ (Texas, Louisiana, and Mississippi). Daniel’s research is situated at the intersection of economic geography, political geography, and geopolitical ecology. Ethnographic fieldwork will be undertaken in late 2025 and early 2026.

Geoffrey Bwireh

Supervisors: Dr Robert Newbery and Prof Matt Baillie Smith

PhD working title: Volunteerism, mixed embeddedness and entrepreneurial behaviour of Congolese youth refugees in Nakivale settlement in Uganda

PhD research summary: Geoffrey’s PhD analyses human capital, volunteerism, social networks, and performance of youth refugees owned micro-enterprises in Ugandan refugee settlements. Existing evidence suggests that engaging refugees in entrepreneurial activities can support their embeddedness within society; at the same time, volunteerism is increasingly being celebrated as a silver bullet strategy for enhancing aid and development in the global South. However, although the majority of the world’s refugee population is hosted in global South countries, research into refugees entrepreneurship has mainly focused on issues of mobility and individuals’ dual-embeddedness within host countries of the global North. This research thus explores human capital, volunteerism and social networks through the experiences of young refugee entrepreneurs living in Uganda refugee settlements.

Janet Clark

Supervisors: Prof Matt Baillie Smith, Prof Katy Jenkins and Dr Bianca Fadel

PhD research summary: Janet’s PhD research is in collaboration with the International Forum for Volunteering in Development (more details here). It explores the changing relationships between volunteering and development as ideas and practices have been challenged by the Covid-19 pandemic, the climate emergency, decolonisation and reduced aid budgets. The research will analyse how organisations working with volunteers are responding to these challenges and whether these responses have prompted a more socially just and equitable reimagining of volunteering.

Jos Bamborough

Supervisor: Prof Matt Baillie Smith

PhD research summary: Joseph’s research project explores concepts at the heart of contemporary thinking around humanitarian response through a lens of ‘everyday’ work within international non-governmental organisations (iNGOs).  It builds on four critical (and overlapping) bodies of literature:  population displacement, humanitarian localisation, supply chain management, and ‘geographies of the everyday’, within the context of conflict in the Middle East, to develop an understanding of how workers manage the flow of goods and services, funds, and information through their supply chains.

Lindsay Bewick

Supervisors: Prof Matt Baillie Smith and Prof Katy Jenkins

PhD research summary: Lindsay's PhD research seeks to critically explore the ways in which entrepreneurial activities enable urban women refugees to create livelihoods opportunities, focusing on three key inter-related lenses – biographies, solidarities and space. Taking the emphasis away from current policy and programming which has a narrow focus on how entrepreneurship leads to local economic contributions, the broader everyday experiences and interactions of urban women refugees will be investigated using visual and participatory methods. The research will take place in Uganda.

Robert Olet Egwea

Supervisors: Prof Matt Baillie Smith and Dr Francis Masse

PhD working title: The impact of tree protection strategies on rural livelihoods in the shea tree belt of Uganda

PhD research summary: Robert’s PhD research investigates the impact of tree protection strategies on livelihoods in Uganda's shea tree belt, a vital ecosystem supporting the livelihoods of millions of people in a region that has experienced significant deforestation in recent years, leading to soil erosion, loss of biodiversity, reduced water quality, poverty, and food insecurity. The study will contribute to knowledge on deforestation, climate change mitigation, and livelihood outcomes in the global South by providing insights into the complex interrelationships between various tree protection strategies, challenges, and livelihoods in the shea tree belt. The original contribution to knowledge in this study lies in the synthesis of the concepts of agency, theory of access and sustainable livelihoods approach to understand these relationships. While previous studies have explored the environmental benefits of tree protection strategies, this study highlights the crucial role of the strategies in supporting the livelihoods of rural communities in the global south, particularly in the shea tree belt.

Shamima Akter Shanu

Supervisors: Prof Matt Baillie Smith and Dr Katie Oven

PhD working title: Voluntary labour in the climate emergency: Exploring the experiences of youth volunteers in the context of the climate-vulnerable Bengal Delta

PhD research summary: Shamima’s PhD research explores the roles of youth volunteers in climate emergency at the Bengal delta in South Asia. This delta is repeatedly affected by disasters and ongoing climate impacts. Despite inclusion in diverse policy objectives and ambitions, young volunteers’ lived experiences, voices and practices are absent from popular, scholarly and policy thinking. Therefore, this research aims to explore the everyday life experiences of those marginal youth volunteers amongst climate vulnerable communities in Bangladesh. This research adopts participatory research approaches to collaborate with diverse stakeholders in the coastal communities in order to generate new knowledge that will contribute to both volunteer and climate change domains separately and combinedly. Shamima’s overall research interests are related to climate change adaptation, disasters risk reduction, water and sanitation, mangrove ecosystem and deltaic ecosystem.

Zohreh Fakhari

Supervisors: Prof Matt Baillie Smith, Dr Bianca Fadel and Dr Reem Refaat Talhouk

PhD working title: Voluntary labour and climate adaptation: The role of humanitarian health interventions

PhD research summary: Zohreh’s doctoral research examines how humanitarian organisations mobilise voluntary labour in response to the health impacts of climate change. Funded by the NINE DTP ESRC Studentship, her project investigates how different forms of unpaid labour shape locally-led adaptation strategies, and the implications for both communities and the volunteers themselves. The study will explore the intersection of humanitarian health interventions, climate adaptation, and voluntary action. By interrogating the humanitarian-climate nexus, Zohreh’s work highlights the overlooked yet vital contributions of community volunteers in climate-affected settings and offers new insights for policy and practice in humanitarian health and climate resilience.

• Recent PhD graduates (2024-2025)

Dr Becky Richardson

Supervisors: Prof Andrew Collins, Dr Katie Oven and Dr John Clayton

PhD title: Children’s engagement and communication with everyday hazards and risks in Nairobi’s informal settlements

PhD summary:  Becky’s research seeks to critically explore child-centred health risk communication within the field of disaster risk reduction (DRR) with children living in informal settlements in Nairobi, Kenya.  Children have the right to be heard and listened to, as stated in the United Nations Convention on the Rights of a Child (UNCRC, 1989) yet their voices rarely contribute to policy or practice despite being a marginalised group.  This research applies a child-centred approach to understand children’s perceptions of hazard and risk that impact their health and wellbeing in school and their neighbourhood. Those risks are then explored further to see how they are communicated within the child’s own networks and linked to local level innovative solutions to reduce risk and improve health and wellbeing. A participatory action research (PAR) method is applied, adopting creative and arts-based tools to enhance engagement, trust, and equality in power relationships. Methods include deep mapping, walking interviews, body mapping, model-making, storytelling, and drawing.

Dr Floor van der Hout

Supervisors: Prof Katy Jenkins and Dr Hilary Francis

PhD title: Women territory defenders’ activism in Bolivia: weaving resistance against extractivism through embodied, careful, and relational politics

PhD abstract: This thesis argues that in their resistance against extractivist projects, women territory defenders in Bolivia weave meshworks of resistance through embodied, affective, and careful politics in which different spaces, people and subjectivities are woven together as the fabric of resistance emerges from the women’s bodies-territories. In my analysis, I bring together anglophone geographies of resistance literature that considers resistance as an emergent practice, shaped by complex entanglements of dominating and resisting power, with anticolonial feminist proposals from Abya Yala that firmly locate processes of resistant becoming within the materialities of women’s bodies that are seen as ontologically inseparable from the territory/land and proposed as primary site of analysis. Conceptualising resistance as emerging relationally across time and space, I address the lack of empirical detail about women territory defenders’ embodied weaving practices in the cuerpo-territorio (body-territory) literature. I furthermore critically analyse how embodied experiences related to extractive violence can lead to the unravelling of these webs of resistance. Bolivia offers a particularly pertinent setting to explore these unravellings, given the current situation of growing authoritarianism, political polarisation, and divisions within social movements in the country. How these political processes play out at the micro-level, particularly at the scale of families and communities, remains largely overlooked in the literature. In this thesis, I aim to deepen knowledge of resistance as an embodied and prefigurative process. I draw on six months of ethnographic fieldwork in Bolivia in 2019 and 2020 across two sites of women’s anti-extractive resistance: the Tariquía Flora and Fauna National Reserve and the Indigenous Territory and National Park Isiboro Sécuré, where I traced the threads of women’s resistance in their embodied emergence through a decolonial feminist epistemological and methodological approach that I call acompañar [to accompany]. I argue that in women territory defenders’ anti-extractive resistance, their body-territories simultaneously become sites of domination and resistance, challenging past-present, individual-collective, and human-nature dichotomies. Webs of resistant relationships are slowly woven across time and space through women’s everyday affective and careful politics that enable and sustain anti-extractive action. The defensoras carefully position themselves, navigating power inequalities, as they weave alliances across difference with external actors in a quickly changing political landscape. While emotions and embodiment enable the weaving of resistance on the one hand, the defensoras’ embodied experiences can also result in the unravelling of the fabric of resistance in context of the violence and temporalities that characterise socio-environmental conflicts. I conclude that prefiguration – ways of being, seeing, and knowing otherwise that foreground care, the relational, the collective and re-existencia (re-existence) – is crucial in imagining and creating post-extractive alternatives. Together, these points illustrate how meshworks of resistance carry the potential to contest as well as reinforce intersecting colonial, patriarchal, and capitalist systems of oppression, as they are always bound up with domination.

Dr Mridula Mary Paul

Supervisor: Dr Francis Masse and Prof Andrew Collins

PhD title: The making of One Health: Emotional and cultural political ecologies of tackling zoonoses

PhD research summary: Although zoonotic diseases have significantly impacted already vulnerable forest-/wildlife-dependant and herder communities in developing countries, the thrust of the global response to zoonoses is surveillance and ‘hotspot’ mapping with the expressed goal of containing the spread “closer to their source” i.e., locations in the global South. The scientific research on zoonoses that inform policies for response are therefore political endeavours as much as scientific ones, because they implicitly confer certain spaces and groups of people with more culpability for zoonotic disease emergence. As a dominant paradigm addressing public health and zoonoses, One Health provides the ideal ground for exploring the cultural politics of the science and expertise underpinning global responses to zoonoses. The PhD project aims to merge the political ecology of human-animal relations and the political ecology of health, thereby contributing to the emerging field of political ecology of zoonoses and One Health.

Dr Robert Bowden

Supervisor: Prof Matt Baillie Smith

PhD title: Localisation and global social change: agency, intent and learning in INGO/supporter relations

PhD summary: My research focuses on the dynamics of INGO/supporter relations in what is a critical conjuncture of external and internal factors affecting many large UK-based INGOs and their role and legitimacy within international development and civil society spaces. How does a large INGO, weighed down by historicised patterns of cultural behaviour adapt to a changing ecology of activism and what does this mean for the organisation and for those who work for it? I develop new conceptual insights based on a longitudinal study of cultural transformation and resistance and consider the implications of this for learning more widely within the sector and beyond.

Dr Sophia Valle-Cornibert   

Supervisor: Prof Katy Jenkins

PhD title: Traces of dignidad. A critical exploration of women’s resistances in the context of extractivism in the Atacama Desert, Chile

PhD abstract: In this thesis, I argue that expanding our comprehension of women's resistance within extractive contexts requires moving beyond impact-driven and anti-extractive narratives. While following the traces of women mobilising in the Atacama Desert, Chile, this research aims to conceptualise women's territory-based experiences and long-standing resistances concerning everyday life with large-scale mining. Drawing on a feminist and decolonial framework, this research critically explores women's diverse and interwoven experiences, particularly explored through the relational ontology of pluriversidad and articulated through the lens of senti-pensar and cuerpo-territorio. In this analysis, I emphasise the contributions of women's emotional, embodied, and territorial experiences to build situated and contextualised conceptualisations of their territory, their positionalities, and always-evolving resistances within the context of extractivism.The thesis is based on eight months of ethnographic fieldwork with a collaborative and participatory intentionality. By focusing on women's oral histories and participatory filmmaking, the research presents three specific arguments. First, it brings attention to women’s place-based imaginaries and representations of territory and breaks with dichotomous and romantic views that align or contrast them with hegemonic extractive representations. Instead, the thesis attempts to comprehend the co-existence of ambivalent conceptualisations rising between women’s diverse ecological, cultural, and extractive territory-imaginaries of the Atacama Desert. Secondly, this analysis provides a deep comprehension of women’s positionalities concerning everyday life with extractivism, arguing the need to extend beyond an impact-driven analysis due to the potential classification, categorisation, or dismissal of their narratives. Ultimately, going beyond the growing literature focusing on women’s resistance to extractivism, this research aims to broaden the analysis based on women’s resistances within contexts of extractivism, arguing that these extend beyond anti-mining narratives. As a result, this research introduces the perspective of Dignidad, a concept arising from women’s emotional, embodied, and territorial ontologies, thus constituting a fundamental idea through which to make sense of women’s situated and contextualised lived experiences and always-evolving resistances in the Atacama Desert. Therefore, this thesis provides an analytical exploration of women’s traces of dignidad, a perspective that is not static but dynamic and continuously being shaped through the experience of resistance.
