In the mountain villages of Nepal, the need for safer, higher-quality housing remains a pressing challenge. This spring, engineering students Kajsa Lilja and Kalle Edström from Chalmers University of Technology joined Build Up Nepal as part of their Master's thesis.

In the heart of Tanzania, where the dry season tests the limits of self-sufficiency, the two Swedish engineering students Yasmine Jakobsson and Johanna Löf are exploring how to reuse greywater. By using local resources and adapting their methods, their study proves that sustainable change doesn't always require high-tech machinery.
