CSAG has been contracted to provide a comprehensive report detailing climate change projections for the city of Johannesburg with a particular focus on storm water management, a critical issue for a city vulnerable to urban flooding. The report will be based on station scale, statistically downscaled, projections of future climate change. The statistical downscaling will be performed by CSAG using in house methodology. Translation of the downscaled projections to relevant statistics, visualizations and summary descriptions will form the bulk of the report with substantial engagement with representatives from the city in order to refine the form and relevance of the resultant information.
