The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
Its been a while since we published a working paper, especially a CASA one, but this has now changed with the release of a new one entitled “Agent-Based Models for Geographical Systems: A Review.” In the paper Alison Heppenstall, Nick Malleson, Ed Manl…

Continue reading »The Urban Zoo project focused on the issues of transfer of disease from animals to humans, in particular in the context of Nairobi, Kenya. This is mostly a medical study, but through the involvement of UCL Development Planning Unit (DPU), issues of urban planning and urban studies were integrated. The new paper “Participatory mapping and food‐centred … Continue reading New paper: Participatory mapping and food‐centred justice in informal settlements in Nairobi, Kenya

The session was structured in the following way: first, each person presented their issue, and then they answer questions that were presented by other panel members. The questions that we managed to … Continue reading Citizen Science 2019: Designing technology to maximize cultural diversity, uptake, and outcomes of citizen science

Jessica – there can be a disconnect between the work on the ground and how it is used in advocacy. On how to use the information to make the world a better place, and hold polluters to account. First, Michael Krochta (Bark) from … Continue reading Citizen Science 2019: Citizen Science in Action: A Tale of Four Advocates Who Would Have Lost Without You

There are 60 participants in the conference that are supported by the NSF to participate in the conference. There was a special effort … Continue reading Citizen Science 2019: Environmental Justice and Community Science: A Social Movement for Inpowerment, Compliance, and Action
