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
