The development of Lilani Hot Springs : an analysis of socio-economic and environmental impacts.Hoole, Ross Johnathan. January 2000 (has links)
Tourism development in remote areas of South Africa is often being proposed as the solution to poor
rural communities' development needs. However, experience indicates that tourism development can
result in a negative impact on a community's culture and way of life. The issue of sustainable
development and what it means sets a base in which the research looked at tourism in rural areas. The
case study on the impact ofthe redevelopment ofLilani Hot Springs as a tourist resort focusses on both
the people and environment. The historical context ofthe hot springs, their discovery, development and
the demise ofthe old resort is investigated. This was undertaken so that lessons learnt from the past can
be taken into consideration with the future development of the resort. This study has included
investigating the viability and sustainability of such a tourist resort in the Umvoti Magisterial District
and in a rural environment. By focussing on the Lilani community, this research project explores the
key factors which have been identified as essential if long-term sustainable tourism is to be achieved
in remote rural communities. An appropriate planning approach which stresses local participation and
decision-making within the context of a holistic strategy for community development is subsequently
proposed. Tourism has the potential ofprotecting the environment while providing social and economic
benefits to the local communities. Clearly ifthe socio-economic needs ofthe local community in which
a tourism development is set are not addressed, it will not succeed but ifthe natural environment, which
is the very asset on which the tourism development is dependent upon, is not protected the resource
which is the source of attracting tourists will be destroyed. / Thesis (M.Sc.) - University of Natal, Pietermaritzburg, 2000.

A geological and hydrogeological study of the Shu Shu thermal springs, KwaZulu-Natal.Gravelet-Blondin, Kent Royson. 11 September 2014 (has links)
The Shu Shu thermal springs are located in central KwaZulu-Natal in South Africa at an altitude
of 250m above mean sea level at the bottom of the Tugela Valley. They have been investigated
in an attempt to ascertain whether or not they possibly share a common origin with fifteen other
springs which are located in a north-northwestern trending, 1000km long zone within the
eastern interior of the country. They have also been studied to establish if they potentially
represent a viable and sustainable geothermal energy resource that may be developed in the
future.
Isotope ratios confirm that the thermal springs are meteoric in origin, and are likely recharged
within a 130km long band located to the west toward the Great South African Escarpment.
These waters then descend vertically to a depth of approximately 1827m – 2153m, at which
point the fractures along which they move close due to escarpment-associated confining
pressure. It is a reduction in this self-same confining pressure along the coastal plain, which
occurs due to the continual removal of overburden, which forces the thermal water to migrate
toward the east along ever-more opening fractures. Due to a slightly elevated geothermal
gradient of 3.1°C / 100m at depth, this groundwater reaches a temperature of approximately
75°C – 85°C as it traverses toward the Shu Shu thermal springs over a time period of > 61
years (at present).
The geochemical signature of the Shu Shu thermal waters is derived through leaching
from the basement rocks through which they pass, with elevated concentrations of Na, K, Ca,
Mg, Fe, Al, Si, F, Sr and SO₄ detected. Once below the floor of the Tugela Valley, at a depth of
approximately 990m, the thermal groundwater commences its ascent, likely along the west-southwest
– east-northeast orientated thrusts and associated fractures of the Tugela Terrane of
the Natal Metamorphic Province. However, the thermal waters abut against those brittle
structures trending north-northwest – south-southeast, which are perpendicular to the axis of
least principle compressive stress, and so are ultimately forced to rise within the Shu Shu
thermal springs.
Prior to surfacing, the temperatures of these waters drop to approximately 67°C as a result of
natural, conductive cooling processes. However intermixing with shallow, cold groundwater,
which is discernible through geochemical and isotopic variations, and atmospheric impacts,
further cool the thermal waters to a surfacing temperature of approximately 50°C. Nevertheless, a binary cycle geothermal energy power plant remains a possibility. Although thermal efficiency
and volume flow rate values are favourable, heat transfer values are low and require further
investigation through exploratory drilling. Nevertheless, the establishment of a 400kW power
plant, should it occur, will typically be sufficient to service 625 rural homes. / Thesis (M.Sc.)-University of KwaZulu-Natal, Durban, 2013.
