Elasticity of demand, price and time: lessons from South Africa's plastic-bag levy

Policy makers in many countries have perceived plastic-bag litter as a problem, and have used a variety of regulatory tools to address it. South Africas current legislation on plastic-bags came into effect on 7 May 2003. It increased the thickness of the plastic used, charged a small levy and required that bags be sold rather than distributed gratis. These regulations sharply reduced consumption of plastic bags in the short term, but unlike the Irish and Danish levies have failed to curb their use meaningfully in the long run. It is suggested that the initial sharp fall in use of bags was a result of loss aversion rooted in an endowment effect (the bags having long been a free good). Once consumers became accustomed to paying for bags, demand slowly rose to its historic levels.

The economic valuation of nature-based tourism in the South African Kgalagadi area and implications for the Khomani San ‘bushmen’ community

The economic importance of the various attributes of dryland nature-based tourism in the Kgalagadi area is generally unknown, as is the distribution of benefits from such tourism. This study seeks to value selected attributes of nature-based tourism in the Kgalagadi area by applying the choice experiment technique and then assessing the potential for nature-based tourism to contribute to the Khomani San ‘bushmen’ livelihoods through a payment for ecosystem services scheme. The values placed on the attributes by park visitors are estimated using the conditional logit and random parameter logit models. The visitors prefer more pristine recreational opportunities, increased chances of seeing predators and disapprove of granting the local Khomani San communities access to grazing opportunities inside the Kgalagadi Transfrontier Park. Notably, the marginal willingness to pay for pristine recreational opportunities across all models ranging from R76.96 (US

Given that previous studies report that the Khomani San are willing to accept reasonable compensation for relevant resource-use restrictions, there is scope for a payment for ecosystem services scheme where visitors could be charged additional park entry fees sufficient to compensate the local communities to accept a restriction of natural resource use in the Kgalagadi area.

The Environment for Development Initiative: lessons learned in research, academic capacity building and policy intervention to manage resources for sustainable growth

Sharing conservation revenue with communities surrounding parks could demonstrate the link between ecotourism and local communities’ economic development, promote a positive view of land restitution involving parks, help address skewed distribution of income in the vicinity of parks and act as an incentive for local communities to participate in conservation even more. This article estimates the visitation demand function for Kgalagadi Transfrontier Park (KTP) in order to determine the appropriate conservation fee to charge visitors to maximize park revenue. The data were generated from contingent behaviour experiments on South African residents at KTP and three other parks deemed as either substitutes or complements for visitors to KTP. Our results suggest that there is sheer underselling of the recreational opportunity at KTP, which implies that there is room for generating extra revenue to support benefit sharing arrangements with the local communities. The conservation fees at KTP can increase by as much as 115%, thereby almost doubling current revenue after accounting for the drop in visitation which will be triggered by the increase.

Analysis of the plastic-bag levy in South Africa

This article estimates the visitation demand function for Kgalagadi Transfrontier Park (KTP) in order to determine the scope for raising fees charged to international tourists in order to fund revenue-sharing schemes for local communities. International and Southern African Development Community tourists account for approximately 25% and 2% of the total number of visitors to South African national parks, with domestic visitors making up the remaining portion. Although small, the South African international tourism market is mature and accounts for a disproportionately large share (around 42%) of net revenue. To estimate visitation demand at the KTP and three other national parks, random effects Tobit Model was used. Using the estimated elasticities, the revenue-maximizing daily conservation fee was computed to be R1 131.94 (US

Sharing conservation revenue with communities surrounding parks could demonstrate the link between ecotourism and local communities’ economic development and promote a positive view of land restitution involving national parks.

The Effect of Land Restitution on Poverty Reduction among the Khomani San “Bushmen” in South Africa

This article reviews the history of the Environment for Development (EfD) initiative, its activities in capacity building and policy-oriented research, and case studies at its centres in Chile, China, Costa Rica, Ethiopia, Kenya, South Africa and Tanzania. EfD promotes research-based policies to manage natural resources as engines of development. Since 1991, the Swedish International Development Cooperation Agency (Sida) has provided funding for students from developing countries to earn a PhD at the Environmental Economics Unit (EEU) of the University of Gothenburg. Returning home, these economists face institutional and academic gaps that limit the adoption of research-based policies. In response, the first EfD centre was founded in 2004, and six more followed. Research focuses on agriculture, climate, fisheries, parks, wildlife, forestry, energy and policy design. This has yielded 200 peer-reviewed articles. Successful policy outcomes depend on relationships with policy makers, community involvement in livelihood strategies, strengthened institutional support, interdisciplinary approaches, and dissemination of research results.
