This Scientific Bibliography of the “Far Northern Drakensberg” is a continuation by the Afromontane Research Unit of the University of the Free State (ARU) to document published and other similar works on the mountains of the summer rainfall area of South Africa. It follows “A Scientific Bibliography of the Drakensberg, Maloti and Adjacent Lowlands” which was published in 2020 (Moffett 2020), and which covered the area between the North-Eastern Cape and the North-Eastern Free State. The current work extends this northward by including articles and publications dating back to 1875 (E.Cohen, on the Lydenburg goldfields) reaching as far as the Wolkberg and Woodbush near Tzaneen in Limpopo Province. Figure 1 shows the boundary of the area covered, and although referred to as the Far Northern Drakensberg in this work, it is identical to that described as the LMEE, Limpopo, Mpumalanga & Eswatini Escarpment by Clarke et al (2022). Although slightly separate from the “lower” escarpment, the mountainous Barberton and adjacent Eswatini area, as well as the Leolo Mountains in eastern Sekhukhuneland are also included. Details on how the boundary in figure 1 was determined are given in Clark et al (2022). Bibliographies on two further ranges in the summer rainfall area, viz. the Magaliesberg in Gauteng province and the Soutpansberg in Limpopo province are to be the subject of future compilations.

Communities increasingly find that the water quality, water levels, or some other resource indicator in their river basins do not meet their expectations. This discrepancy between the desired and actual state of the resource leads to efforts in river basin restoration. River basins are complex systems, and too often, restoration efforts are ineffective due to a lack of understanding of the purpose of the system, defined by the system structure and function. The river basin structure includes stocks (e.g., water level or quality), inflows (e.g., precipitation or fertilization), outflows (e.g., evaporation or runoff), and positive and negative feedback loops with delays in responsiveness, all of which function to change or stabilize the state of the system (e.g., the stock of interest, such as water level or quality). External drivers on this structure, together with goals and rules, contribute to how a river basin functions. This book reviews several new research projects to identify and rank the twelve most effective leverage points to address discrepancies between the desired and actual state of the river basin system. This book demonstrates that river basin restoration is most likely to succeed when we change paradigms rather than try to change the system elements, as the paradigm will establish the system goals, structure, rules, delays, and parameters.

Drylands cover more than half sub-Saharan Africa and are home to nearly 50 percent of the region's people. This review documents resilience to climatic variability of fish resources in the sub-Saharan drylands. It also examines the potential for increasing their supply through improved use of available bodies of water, especially small reservoirs.
