The grassland biome of the southern Drakensberg region of South Africa is characterized by a relatively rich floral biodiversity, including a high level of endemics. Land use in the area was traditionally dominated by livestock ranching based mainly on indigenous grassland that conserved biodiversity to some degree. Currently however, market demands and risk factors are shifting land use in the area to a matrix of beef, cropping, dairy and particularly, towards plantation forestry. A spreadsheet model was constructed to understand how expected land use conversion will likely influence th

The Rhodes trout fishery, located in the North Eastern Cape, is one of South Africa’s premier fly-fishing destinations. The integrity of the fishery is, however, under threat due to various land-use practices, which could weaken its appeal as a tourist attraction. The aim of this study is to estimate the amount recreational users are willing to pay for a project to improve the trout habitat of waters managed by the Wild Trout Association (WTA) in this fishery in order to improve its fish population density by 100 per cent.

Background: To address the structural food deficit and top down extension system that persisted for decades, the government of Ethiopia has introduced a new extension system, called Participatory Demonstration and Training Extension Systems, which serves more than 80% of the total population. As the program was streamlined to fit the different agro-climatic condition of the country, the extension approach practiced in the Tigray region (research area) was called Integrated Household Extension Program.

Background: In South Africa, the idea that the township economy needs to be ‘revitalised’ has begun to gain significant political traction. The Gauteng provincial government has responded to this challenge by setting out a strategy that promises to channel resources and create opportunities for micro-enterprises. The paper responds to development interventions such as this through interrogating the nature of the challenges facing micro-enterprises that need to be overcome in South African townships.

Ecosystem-based adaptation (EbA) is increasingly being promoted as a cost-effective means of adaptation to climate change. However, in spite of considerable international press, there is still little evidence to substantiate this claim. This study proposes a method through which the cost-effectiveness of EbA strategies can be evaluated against alternative adaptation options, and contributes to South African literature on the subject.

Invasive alien plants have a negative impact on ecosystem goods and services derived from ecosystems. Consequently, the aggressive spread of invasive alien plants (IAPs) in the river catchments of South Africa is a major threat to, inter alia, water security. The Olifants River catchment is one such a catchment that is under pressure because of the high demand for water from mainly industrial sources and unsustainable land-use, which includes IAPs. This study considered the cost-effectiveness of clearing IAPs and compared these with the cost of a recently constructed dam.

This study explores the influence of incidence of poverty and plot-level perception of soil degradation, on soil conservation behaviour of small subsistence farmers in the central highlands of Ethiopia. The study results confirm that poverty in assets significantly reduces the probability of soil-conservation efforts as measured by use of stone/soil bund structures in the highlands of Ethiopia.

Inadequacies in the indication of cultural ecosystem services (CES) are a hindrance in assessing their
comprehensive impacts on human wellbeing. Similarly, uncertainties about the quantity and quality of
CES, in real time and space, have hampered the ability of resource managers to precisely take responsive
management actions. The aim of the study is to demonstrate, how CES indicators can be identified and
qualified in order to link CES to human wellbeing, and to integrate them into the ‘ecosystem services cascade’
