This article is the second of a two-part series describing the development of a ten-year plan for primary health care facility development in Soweto. The first article concentrated on the political problems and general methodological approach of the project. This second article describes how the technical problem of planning in the context of scanty information was overcome. The reasoning behind the various assumptions and criteria which were used to assist the planning of the location of facilities is explained, as well as the process by which they were applied. The merits and limitations of this planning approach are discussed, and it is suggested that the approach may be useful to other facility planners, particularly in the developing world.

The Golden Gate Highlands National Park (GGHNP) is well known for its impressive sandstone formations. While previous geoscience research in the park has focused on geology, palaeontology, slope forms and the prominent lichen weathering, remarkably little has been written on the diversity and possible origins of sandstone phenomena in the region. The objectives of this study were (1) to present a geomorphological map of prominent and interesting landforms for particular portions of the park and (2) to document the variety of macro- and microscale sandstone formations observed. During field work, we undertook global positioning system measurements to map landforms and, in addition, measured the dimensions of several landform types. A Schmidt hammer was used to conduct rock hardness tests at a variety of localities and lithologies for comparative purposes. We indentified and mapped 27 macro- and microscale sandstone landforms, of which 17 are described in detail. It is demonstrated that for the most part, the landforms are a likely product of surface lithological reactions to a regional climate characterised by pronounced multitemporal temperature and moisture shifts, recently and in the past. However, many of the geomorphological processes producing landforms are controlled by microclimates set up by factors such as macro- and microtopography. <p><strong>Conservation implications:</strong> The GGHNP is best known for its geological, geomorphological and palaeontological heritage. This paper highlights the diversity of sandstone geomorphological phenomena, many of them rare and ‘unique’ to the region. Not only are these landforms of aesthetic interest to tourists, but they also provide microhabitats for biota. Thus, conservation of biota requires associated conservation of geo-environments where they are established.</p><p><strong>How to cite this article:</strong> Grab, S.W., Goudie, A.S., Viles, H.A. &amp; Webb, N., 2011, ‘Sandstone geomorphology of the Golden Gate Highlands National Park, South Africa, in a global context’, <em>Koedoe</em> 53(1), Art. #985, 14 pages.

As government administrative data sets are increasingly made available for new (non-administrative) purposes, there is a need to improve access to such resources for voluntary and community organizations, social enterprises and private businesses for statistical analysis and evaluation purposes. The Justice Data Lab set up by the Ministry of Justice in the UK presents an innovative case of how administrative data can be linked to other data held by organizations delivering public services. The establishment of a unit within a secure setting holding evaluation and statistical expertise has enabled providers of programmes aimed at reducing re-offending to obtain evidence on how the impact of their interventions differs from that of a matched comparison group.
