Climate change threatens the distribution of major woody species and ecosystem services provision in southern Africa
<p>Species occurrence points used in this study to investigate the effect of climate change on the distribution of eight tree species in 18 countries in southern Africa, covering 36% of the continent. We proposed a loser/winner ranking of the species based on the changes in climatic suitability within their historical distributions as well as future gains and losses of suitable areas. We interpreted these findings in terms of changes in the provision of key ES (timber, food, energy, and medicine), and identified hotspots of ES provision decline. We used species presence data from the Global Biodiversity Information Facility, climatic data from the AfriClim dataset, and the MaXent algorithm to project the changes in species' land suitability. </p>
Future Food Security in Africa under Climate Change
<p>This excel file contains data tables (S2-S3) also found in the supplementary materials of the publication titled "Future Food Security in Africa under Climate Change". The tables included here include a regional breakdown of African countries (Table S2), available calories for direct or indirect human consumption under diverse food loss and waste pathways (Table S3), and data on national caloric deficits under different scenarios (Table S4). </p>
Data_The impact of derivatives use on systemic risk of Africa's banking system

CS3 Land-based abalone IMTA - bioeconomic model South Africa 2022
<p>Data set containing bio-economic modelling results from the estimated growth of land-based abalone fed with IMTA produced macroalgae in South Africa. The dataset contains calculations and modelling of a baseline scenario and four alternative scenarios according to the geographical location of the abalone farm and the feed strategy with or without IMTA macroalgae. Sensitivity analysis for productivity and feed price/FCR is provided.</p>
