ACDI draws together a network of researchers at UCT and beyond to engage with ACDI in various ways, from teaching and student project supervision, to research and knowledge influencing. 

ACDI’s offers both institutional and individual membership. The aim is to be inclusive, in the spirit of collaboration and community-building, rather than exclusive. Institutional membership involves both recognised research groupings, academic departments and other university entities whose area of work intersects strongly with ACDI, and who have a history of active membership of ACDI.

ACDI’s core team acts as a hub, which aims to provide the services that enable the network to be more than the sum of its parts. The team comprises the Director, administrative support staff, and communications team. Additionally, the HQ includes a number of students, Postdoctoral researchers, and project managers who work on ACDI-led projects in collaboration with the ACDI network, as well as the ACDI Masters Convener, who coordinates all aspects of the flagship ACDI Masters in Climate Change and Sustainable Development.


Individual members are known as Associates, and are people at UCT who actively engage with ACDI through research, teaching, student supervision or other activities. Associates may or may not be jointly-affiliated to an institutional member. Associates will have research and teaching interests that overlap substantially with the ACDI intellectual domains.

  • Res Altwegg, Centre for Statistics in Ecology, Environment and Conservation (SEEC)

    Designation: Associate Professor, Department of Statistical Sciences
    Expertise: Statistical ecology; wildlife demography

    Associate Professor Res Altwegg

    Res Altwegg is an associate professor at UCT's Department of Statistical Sciences.

    "Decision making in conservation often depends on observational data sets where key processes cannot be observed directly. We are estimating wildlife demography from capture-mark-recapture data using models that explicitly account for the observation process," Res explains about his work at SEEC. Current projects focus on the declining African penguin and the rare but increasing peregrine falcon, among many other species. 

    Res has been studying the connection between life-history evolution and population/community ecology. Conceptually, he strives to combine field observations with controlled experiments and theoretical concepts, and aims to directly connect theory and data through statistical methods, and often uses the Akaike Information Criterion (AIC) to evaluate how well his data support different models corresponding to different biological hypotheses.

    One of the main projects Res has worked on, aims to understand the range dynamics of Southern African birds. Many of these birds are presently expanding their range, while others are losing ground. He has been examining the demography of these species to learn what may drive their local population dynamics, and developing methods to quantify range changes more reliably. This work is in collaboration with Dr Birgit Erni at the Department of Statistical Science (UCT) and his colleagues in the Global Change Research Group at SANBI, Dr Guy Midgley and Dr Phoebe Barnard.

    For his PhD, Res investigated predator-induced plasticity in the life history of water frogs (Rana lessonae / esculenta). Using artificial ponds and terrestrial outdoor enclosures, he was able to manipulate the growth environment and examine the reaction of these animals during two different stages in their complex life cycle. For his Diploma (MSc), he investigated dispersal between local populations within a metapopulation of House Sparrows (Passer domesticus), and examined how the decision to disperse depended on an individual's age, sex, and morphological characteristics.

  • Lindsay Gilson, Plant Conservation Unit (PCU)

    Designation: Associate Professor and Deputy Director: Plant Conservation Unit
    Expertise: Applied palaeoecology, conservation and ecosystem management; theoretical ecology: resilience, thresholds, heterogeneity, variability, complexity and non-equilibrium; linking ecological and social systems

    Associate Professor Lindsey GillsonLindsey Gillson is Associate Professor and Deputy Director at the Plant Conservation Unit, Department of Biological Sciences, University of Cape Town. Her interests include landscape ecology, conservation biology and applied palaeoecology. Her research focusses on long-term ecosystem dynamics, and the implications for conservation, sustainability and ecosystem services. She has a focus on African ecosystems, especially savannas, and is interested in multidisciplinary studies of these complex socio-ecological systems. She is author of “Biodiversity Conservation and Environmental Change: Using palaeoecology to manage dynamic landscapes in the Anthropocene.

    Understanding landscape change over time is essential in predicting and managing ecosystem services sustainably in the future. Climate change interacts with multiple other drivers, including land-use, fire and herbivory, and palaeoecological studies can help in unravelling these complexities. It is especially important to understand how, when and why ecosystems reach tipping points, when sudden changes can have dramatic impacts on biodiversity and socio-ecological systems.

    As part of the ACDI-funded project “Benchmarks for the Future” students James MacPherson, Cherie Forbes, and Abraham Dabengwa undertook palaeoecological studies near biome boundaries, enabling their resilience (or otherwise) to be studied over long-time periods. This project complements ongoing work by Professor Timm Hoffman and his team, who use repeat photography to investigate landscape changes in southern Africa over the past century. Further projects involve the “main-streaming” of palaeoecological data into long-term studies of sustainability and ecosystem management. As well as this research, Lindsey Gillson contributes to ACDI masters teaching through through introductory core lectures on biodiversity and climate change. She also runs an optional, two week module on biodiversity and climate change, and is a member of the ACDI Steering Committee. Read more.

  • Piotr Wolski, Climate System Analysis Group (CSAG)

    Designation: Research Officer, Climate Systems Analysis Group
    Expertise: Climate change and hydrology

    Piotr Wolski

    In principle, Piotr is a hydrologist, but in terms of his recent research and activities, he seem to be sitting on a fence, between water and climate. So, he can define himself as a hydro-climatologist. Since joining CSAG formally in 2012, Piotr has been using climate model outputs for hydrological analyses in the context of climate change impact assessment, attribution and seasonal forecasting. He has also been running attribution experiments. Piotr also works on various aspects of visualization and presentation of climate data, that include articulation of uncertainties, developing visualizations such as "plume plots", and analytical tools such as "SOM-space trajectories", and doing all sorts of analyses that often include bootstrapping. It thus seems that in broader context, he revels in figuring out how the uncertainties and errors propagate through the various processing steps that are involved in translating climate data into (hopefully) useful information. Read more.
