This article reflects on the experiences and insights gained during the LDE Thesis Lab on Sustainable Urbanism in East Kalimantan. Our group, consisting of nine students from Leiden University, Delft University of Technology, and Erasmus University Rotterdam, spent two weeks in Samarinda, where we were hosted by Mulawarman University. During this intensive period, we followed a fully packed program that offered a comprehensive introduction to the region’s complex socio-economic and environmental dynamics, highlighting the many nuances and grey areas inherent in these interactions. The LDE program offered an immersive way to connect and collaborate with Mulawarman students, to provide in-depth context and meaning to our individual thesis projects. We have broken up our thesis topic into three groups, environment/biosphere, society, and economy, following the SDG wedding cake.

Within the group, two students focused their thesis specifically on environmental aspects, examining the impacts on the biosphere and exploring how urban development intersects with ecological systems. The biosphere is the foundation, and starting point of the following linked-in articles about how our theses relate to the greater LDE thesis lab topic of Sustainable Urbanism in East Kalimantan.
