Resilient Peri-Urban Transformations and Sustainable Land Governance: Current Discourses, Dynamics and Governance to Cope with Drastic Socio-Spatial Transformation
Dortmund, 16 – 17 November 2026
Peri-urbanization, a global phenomenon driven by rapid urban growth, weak governance, and unaffordable housing, creates transitional hotspots of land transformation. These areas feature mixed land uses, competing claims, institutional fragmentation, and social marginalization. Environmental consequences include farmland loss, habitat fragmentation, flood risk, and water stress. Yet peri-urban regions also foster innovation through hybrid governance.
Overlapping formal and informal institutions produce legal ambiguities—e.g., conflicting urban and rural zoning—leading to insecure tenure, informal settlements, and harm to marginalized groups. Peri-urban areas are vital for resilience, providing “edible green infrastructure” such as food production, flood regulation, and biodiversity corridors.
A resilient framework must balance urban growth, rural livelihoods, ecosystems, and equity. This requires moving beyond static zoning toward adaptive, polycentric governance. Key elements include participatory land rights mapping, flexible tools for peri-urban agriculture, cross-sectoral coordination, and recognizing informal actors as legitimate stakeholders. The framework should capture dynamic transformations and complex actor interactions.
Consequently, the conference invites participants to attend and discusses keynote speeches and presentations under three thematic tracks:
Track I - Peri-urban / peri-urbanisation - a theoretical perspective to contextualise and localise peri-urban and peri-urbanisation in territorial governance.
Track II - Dynamics of peri-urbanization - Analysis of the underlying drivers of peri-urban growth patterns of land use change, demographic shifts, infrastructure and evolution of peri-urban economies including case studies or comparative analysis of impact on livelihood and natural ecosystems in different regions.
Track III - Governance frameworks for resilient peri-urban development – exploration of land governance and, in particular, land management frameworks for sustainable peri-urban development. Key discussion topics include planning instruments and mechanisms to anticipate, address and govern for climate impact mitigation and adaptation, as well as the roles of various actors - local governments, the private sector, civil society, and communities - in the planning and managing peri-urban transformation.

Prof. Dr. Manja Hoppe Andreasen

Department of Geosciences and Natural Resource Management, Section for Geography – Land, Environment and Society, University of Copenhagen, Denmark
Manja Hoppe Andreasen is an Associate Professor of human geography at the Department of Geosciences and Natural Resource Management at University of Copenhagen. Her research is concerned with the drivers and dynamics of urban expansion in rapidly urbanizing low- and middle-income countries. Her research examines the motivations and logics of the diverse actors involved in land transactions, investments and property development in urbanizing peripheries and how urban governance arrangements shape the dynamics of peri-urban transformation. Her research offers insights with implications for urban policymakers and planners seeking to foster inclusive, resilient and sustainable cities and engages with key urban policy agendas, including land formalization, settlement upgrading, infrastructure expansion, sustainable transport systems and climate change resilience. She has conducted extensive fieldwork in Tanzanian and Ghanaian cities. While strongly bent towards qualitative methodologies, she has an aptitude for integrating insights from qualitative, quantitative and spatial methodologies.

Prof. Dr. Rita Lambert

University Collage of London (ULC), London, United Kingdome
Rita Lambert is an urban development planner and architect originally from Ethiopia. She has over twenty-five years of experience in academia, research, and professional practice across Latin America, Africa, and Southeast Asia. Her work is grounded in feminist political ecology, socio-environmental justice, and systems thinking, and seeks to make visible the historical legacies and contemporary processes that keep people and ecosystems in conditions of vulnerability, while identifying pathways towards more equitable and sustainable urban futures. She examines a range of life-sustaining issues, including water, energy, housing, food, and ecological systems, and explores how policies and everyday practices interact. Urban land has been a central lens in her work, and she has made significant contributions to debates on peripheral urbanisation, land governance, informality, and urban and environmental planning. Through her research, she has examined the violence embedded in planning and land management systems, as well as the mechanisms through which informal and illegal forms of land acquisition become legitimised. She also investigates the reproducion of environmental injustice across cities and regions, exposing low-income communities and ecosystems to heightened vulnerability, risk, and dispossession. Rita has extensive experience leading multidisciplinary research teams as Principal Investigator and Co-Investigator and working in close partnership with civil society organisations, NGOs, community groups, and public authorities. She consistently bridges research, policy, and practice to support socially just and environmentally sustainable urban development.
