Many protected areas are not successfully conserving biodiversity, often despite adequate management within their borders. Changes in land use outside protected areas can alter ecological function inside protected areas and result in biodiversity loss given that protected areas are almost always parts of larger ecosystems. Economic incentives are seen as one of the most promising avenues to influence conservation goals.

This paper analyzes the interaction between North (technology rich and gene poor) and South (gene rich but technology poor) in relation to bioprospecting in the life sciences industries. This sector is modeled as a vertical industry with a sequential R and D process where both contributions from North and South are necessary to develop new drugs.

To the extent that diversifying income portfolio is used as a strategy for shielding against production risk, both individual risk aversion and weather uncertainty could affect crop diversification decisions. This paper is concerned with empirically assessing the effects of risk aversion and rainfall variability on farm level diversity.

Community-based natural resource management is frequently proposed as a solution to poverty in rural Africa. The extent of Namibia's CBNRM programme's success in terms of joint ventures between the private sector and communities has not been comprehensively analysed.

The restitution of parkland to the Khomani San “bushmen” and Mier “agricultural” communities in May 2002 marked a significant shift in conservation in the Kgalagadi Transfrontier Park and environs in South Africa. Biodiversity conservation will benefit from this land restitution only if the Khomani San, who interact with nature more than do other groups, are good environmental stewards.

Namibian hake is the most important fish resource in Namibia. This monograph is a compilation of all the hake data, historic and recent, that has been used to inform stock assessment and management since the late 1970s.

Many rural areas of Africa are characterised by high levels of unemployment, poverty and increasing population densities. Arid climates and erratic rainfall also make many of these areas marginal for agriculture and offer few alternative employment opportunities. Ecotourism in these areas can offer a sustainable land use option that promotes biodiversity conservation, can assist in poverty reduction and promote local socio-economic development. Receipt of benefits from ecotourism is also claimed to improve community attitudes towards conservation.

Increasing populations, together with the impact of climate change, are resulting in greater competition for land and a necessity for sustainable land use. Tourism can provide a flow of benefits from conservation to rural communities to reduce poverty and promote biodiversity conservation. Three key mechanisms of sustainable tourism to reduce poverty are discussed:  employment, value chains and equity. These are based on primary data and a thorough literature review.

In an attempt to control the environmental problems posed by plastic shopping bags, the South Africa government combined elements of regulation with a levy per bag, similar to that applied by the Irish.

Charging for bags commenced in May 2003 with a fixed nominal price of 46 rand cents for 24-l bags across all retailers, which was subsequently lowered. The levy charged had only short run success. Over time, the effectiveness of the levy has continued declining despite its comprehensive application at checkout points.
