TIME: 16.00-17.30 (CET).​
ACTIVITY: CEDLA EXHIBITION & WEBINAR
VENUE: CEDLA, Binnengasthuisstraat 46, 1012 ZD Amsterdam
CEDLA is currently hosting the exhibition Resisting the Tide: Blue Justice and Collective Actions in Fishing Communities of Latin America and the Caribbean in the hallway, upstairs in Gasthuiskerk. This photographic-artistic poster series, created by a transdisciplinary team of scholars and fishing communities in Costa Rica, Mexico, Chile, and Colombia, amplifies the voices of coastal peoples as they defend their livelihoods, knowledge systems, and spiritual ties to the maritory. It highlights strategies of resistance to industrial fishing, privatization, pollution, overexploitation, and the growing militarization and criminalization of oceanic communities.
We invite everyone to attend the upcoming related events:

What is this dissertation about?
The extractive appropriation of resources continues to reshape territories worldwide, driving environmental destruction, social injustices, and political turmoil. In response, struggles for social and environmental justice arise at extraction sites, challenging the burdens of resource exploitation, corporate irresponsibility, and power abuse.
Through case studies of gas extraction in Groningen, the Netherlands, and building material mining in Quetzaltenango, Guatemala, this dissertation examines the territorial transformations and power struggles at extraction sites. It further explores how place-based resistance movements can engage in translocal learning and solidarity bridges - connecting territories and grassroots organizations - to confront shared injustices and articulate broader demands for justice.
How did the research come about?
Throughout her research, Hannah collaborated with grassroots movements, civil society organizations, academic institutions, and water authorities in both regions. She was also a fellow in the EU-funded NEWAVE network, that sought to address pressing water governance challenges around the world.

Researching displacement together: co-producing knowledge with displaced women in Colombia
SPEAKERS: Sonja Marzi, Radboud University and The London School of Economics and Political Science
DISCUSSANT: Conny Roggeband, University of Amsterdam
DATE: 12 December
TIME: 15:30
ACTIVITY: CEDLA LECTURE
VENUE: Vox-Pop, Binnengasthuisstraat 9, Amsterdam
This lecture examines the experiences of 24 displaced women in Colombia and the challenges they face while rebuilding their lives in Bogotá and Medellín. Based on co-produced knowledge, it centres the women’s own understandings and descriptions of displacement, rather than treating it as an abstract idea. The lecture explores the economic, social, and political forms of violence that drive displacement and continue to shape urban life long after resettlement. These forms of violence are closely interconnected, producing lasting insecurity. The women’s accounts blur conventional boundaries between scales and types of violence—whether political violence at national, regional, or neighbourhood levels; state violence through action or neglect; or interpersonal harm. Their experiences show how these forces intersect and reinforce one another, making displacement a complex, ongoing condition rather than a single event.
