Holocene environmental changes derived from a montane pollen sequence in the KwaZulu-Natal midlands, South Africa.
(2013)There is a limited understanding of the climatic history of summer rainfall regions of South Africa, especially the east coast, even though palaeo-research has become a popular technique used in southern Africa to determine ... -
Husbandry practices and mitigation of human-carnivore conflicts : a case of the Maasai Steppe, Tanzania.
(2010)Biodiversity losses are often influenced by humans due to increased demand over natural resources and retaliatory killing of wildlife as a result of human–wildlife conflicts. Large carnivores are in decline globally due ... -
The impact of a change in climate on small-scale farmers: case studies of the Khokhwane, Sizanenjana and Richmond communities in KwaZulu-Natal, South Africa.
(2016)A large percentage of land use in South Africa is used for agricultural purposes, as this sector serves as the economic backbone of the country. A change in climate is likely to result in an increase in the frequency and ... -
The impact of tourism on agriculture in the Okavango Delta, Botswana.
(2003)In recent years the use of tourism as a development strategy by third world governments has increased, resulting in the intersection of international tourism and local agricultural strategies. The aim of this thesis is to ... -
The impacts of tourist and residential development on the KwaZulu-Natal north coast : Umhlanga Rocks to Salt Rock.
(2005)The multiple uses of coastal space, the implications of coastal processes on society and the fragility of the marine - terrestrial interface requires integrated and sustainable coastal management strategies - one where ... -
The influence of bioclimatic and topographic variables on fire occurrence and frequency within the Ethekwini Municipal Area.
(2021)Fires have been used for decades as a land management tool. Environments such as grasslands and fynbos depend on fire to maintain their ecological integrity. Fires can also become a disturbance in some ecological zones. ... -
Informal communities and their influence on water quality : the case of Umlazi.
(2003)Water is the most important resource which is essential for sustaining all life forms, since without it, life cannot exist and industry cannot operate. However, increasing concern is being expressed at the rate of degradation ... -
Informing reforestation practices : quantifying live forest above ground biomass of a randomly mixed natural forest plantation using GIS and remote sensing models.
(2017)Restoration of natural forests is viewed as one of the effective and viable approaches for mitigating and adapting to climate change. However, maximising the carbon capture and storage of naturally mixed forest plantations ... -
Integrated conservation-development : a geographical analysis of policy and practice in northern Maputaland.
(2001)The thesis examines the genesis and implementation of integrated conservation development and associated projects in northern Maputaland during the 1980s and 1990s. The premise upon which this study is based is that there ... -
Integrated local governance and development planning : a case study of the greater Louis Trichardt transitional local council.
(2000)With apartheid having left an imprint of spatial fragmentation in the South African urban and rural landscape, there is a major challenge in most places in South Africa to create integrated systems of local governance. ... -
Integrating remote sensing and geostatistics in mapping Seriphium plumosum (bankrupt bush) invasion.
(2016)The impacts of plant species invasion in natural ecosystems have attracted geo-scientific studies globally. Several studies have demonstrated that the effects of invasive species can permanently alter an ecosystem structure ... -
Inter-relationships of poverty and environmental degradation in South African black communities.
(1994)Abstract available in PDF. -
Intergrating environmental variables with worldview-2 data to model the probability of occurence of invasive chromolena odata in forest canopy gaps : Dukuduku forest in KwaZulu-Natal, South Africa.
(2013)Several alien plants are invading subtropical forest ecosystems through canopy gaps, resulting in the loss of native species biodiversity. The loss of native species in such habitats may result in reduced ecosystem ... -
Intertidal salt-marsh foraminifera as sea-level indicators : lessons from the South African coastline.
(2016)Microfossils of the group foraminifera are widely used as robust, high-precision sea-level proxy indicators associated with salt marshes. These microfossils exhibit vertical zones related to elevation across the intertidal ... -
Investigating livestock dynamics in relation to livestock water productivity in smallholder mixed crop-livestock systems : a case study of Ntshiqo in the Eastern Cape.
(2016)Livestock provide net benefits such as food production (milk, meat), raw materials (wool), draught, manure, cultural practices, income and investment, and can improve the resilience of smallholder mixed crop-livestock ... -
Investigating the contribution of the biodiversity stewardship programme in achieving grassland biome conservation in KZN, South Africa.
(2014)Research into biodiversity stewardship and its potential as a mechanism for conservation implementation in South Africa is limited. Conservation implementation tools aimed at achieving conservation targets are espoused ... -
Investigating the utility of SPOT 5 imagery and artificial neural networks, in the identification and mapping of Acacia mearnsii within environments of varying complexity
(2009)The impacts of invasive species on the environment, human health, and the economy continue to gain interest from public and private agencies, scientists, and the media. This study aimed to investigate the utility of SPOT ... -
An investigation into estimating productivity, above ground biomass and leaf area index of Eucalyptus grandis using remotely sensed data and a process-based model.
(2007)South Africa depends largely on afforestation programs for its timber supplies due to the great demands for fiber and wood products. This has brought discomfort to other water users who have advocated that the effects of ... -
An investigation into land capability classification in Eritrea : the case study of Asmara city environs.
(2004)The problems of land resources degradation as a result of misuse of arable land for non agricultural development and lack of appropriate methods and guidelines for land resources assessment are currently evident in Eritrea. ... -
An investigation into residential desegregation : a case study in the Durban Functional region.
(1996)A number of mechanisms were used in the past to racially divide South Africa's population, among them, the most notable being the Group Areas Act. Apartheid was more than just the physical separation of race groups. It ...
