Abstract:
Abstract The Karoo region of South Africa is an ideal laboratory to use ambient seismic signals to map the shallow subsurface, as it is a quiet and pristine environment with a geology that is relatively well known. Ambient seismic signals were continuously recorded for a ten week period between August and October 2015. The ambient seismic noise network consisted of two groups of 17 temporary, stand-alone seismic stations each. These were installed in the southeastern Cape Karoo region, near the town of Jansenville. Here we present data on the retrieval and coherency of Rayleigh surface waves e

Abstract:
ABSTRACTThe position of the Falkland Islands adjacent to the South American continental margin belies the close association of their geology with that of South Africa. A Mesoproterozoic basement is unconformably overlain by a Silurian to Devonian succession of fluvial to neritic and shallow marine, siliciclastic strata. This is disconformably succeeded by a largely Permian succession that, near its base, includes a glacigenic diamictite and, thence, passes upwards into a succession of deltaic and lacustrine strata. The lithological succession and the character of its deformation bear striking

This study reviews the oversight roles played by municipal councillors in Alfred Nzo District Municipality, Eastern Cape Province, South Africa. The objective is to determine the appropriate strategies that can be recommended for improving effectiveness of leadership, i.e., council structures. This is against the backdrop of the Auditor-General’s audit report for three financial years (2008–2011), which revealed the weakness of the systems of the municipal councils, including internal controls and inadequate leadership. These audit findings had been highlighted as the basis for irregular, frui

Abstract Fossil wood is described from the Late Permian Middleton Formation, Adelaide Subgroup, Beaufort Group of the Karoo Supergroup in the Easter Cape Province, South Africa. The wood consists of in situ tree trunks up to 9 m long, partially enclosed in fine-grained sandstone surrounded by argillaceous mudstone and siltstone. The strata are poorly exposed due to the eroded and denuded land surface. All are lying horizontally and none are in upright growth positions.

This article considers the prevalence of sustained agricultural practices (particularly large scale gardens of the homestead) and questions current public debate that permaculture strategy is foreign to South Africa. The paper speaks on recent ethnographic work by the author in rural parts of the Eastern Cape, or the former Transkei. The article makes comparisons to some of the founding principles of permaculture theory and practice to suggest that current agricultural practices and homestead (umzi, plural imizi) settlement patterns follow closely to “permaculture ideals” in theory and practic

At the centre of the water law reform process initiated by the first democratic government of the Republic of South Africa (RSA) lay the challenge of transforming away from apartheid water injustices. Reform culminated in the promulgation of new legislation, regarded internationally as ambitious and forward-thinking legislation reflective of the broad aims of integrated water resource management (IWRM). However, implementation of this legislation has been challenging. This paper analyses institutional dysfunction in water management in the Sundays River Valley Municipality (Eastern Cape Provin

Hydrogeologists have faced serious challenges worldwide in the characterization of fractured rock aquifers due to the heterogeneous nature of the imbedded geology. The bulk flow parameters in the Karoo strata in South Africa are specifically uncertain since most models are based on homogenous block systems.

Smallholder agriculture is faced with so many challenges despite all the policies and programmes that have been channelled towards ensuring improvement in this sector. Improving smallholder agricultural productivity requires that smallholder farmers gain access to reliable and adequate farmer support services such as physical infrastructures like good road network, functional irrigation facilities, extension services, finance and efficient marketing system. However, these support services are lacking in a vast majority of the rural communities in which the smallholder farmers live and work. Th
