This paper describes the development and rationale of a holistic and transparent approach for evaluating the ecological, social and economic trade-offs in water allocation in order to set the ecological Reserve (freshwater allocation) to aquatic ecosystems.
This paper uses empirical data on the crustacean and linefish fisheries to estimate the potential impacts of changes in freshwater flows on the industry, using a modelling approach.
The paper provides and tests empirically a conditional resource curse theory, postulating that the relative effectiveness of the contenders plays a crucial role in determining whether resources are a curse or a blessing.
The paper shows that unstructured lending from international credit markets can create incentives to loot the country; and an enhanced likelihood of looting causes greater political instability, and diminishes growth.
The paper gives guidance on the ways of reducing pollution in a township settlement.
The authors studied the potential trade-off between countries’ investments in mitigation versus adaptation to climate change. Mitigating greenhouse gases may be a public good, but adaptation to climate change is a private good, benefiting only the country or individual.
Climate change mitigation presents us with a social dilemma: while mitigation benefits everyone, individuals lack the incentive to alter their behaviour, since they can reap its benefits while failing to reduce their own emissions.
This paper explores whether any investment products or strategies in South Africa take environmental sustainability into account. By looking at how environmental, social, and governance (ESG) criteria are used in investment decision making, we found that most socially responsible investment products and responsible investment strategies largely focus on infrastructure, development, and black economic empowerment.
Wetlands are commonly understood to have the capacity to reduce the loads of excess nutrients, pathogens, sediments, and other contaminants generated by various activities in their catchment areas. However, quantifying these “services” is difficult and most research in this field has concentrated on artificial treatment wetlands. Understanding the value of their water treatment characteristics, as well as the other services they provide, is increasingly recognized as essential to achieving a balance between conservation and activities that degrade or replace wetlands.
This paper investigates the use of charges and standards in dealing with a common externality, plastic litter from shopping bags in Botswana. The country passed a plastic bag tax (effective 2007) to curb the plastic bag demand. Interestingly, the legislation did not force retailers to charge for plastic bags, which they did voluntarily at different prices.
Tourism development provides an important opportunity for reducing pressures on the delta’s natural resources as well as reducing people’s dependence on the these resources for their livelihoods.
Wetlands play a significant role in removal of organic agricultural pollutants from rivers. A study conducted in the Western Cape, South Africa, shows that small wetlands can play a significant cumulative role in the amelioration of the quality of water emanating from their catchment areas, and that the value of this service is high enough to warrant their protection.
This paper uses data spanning different pricing regimes to estimate the aggregate agricultural supply response to price and non-price factors in Zimbabwe.
This paper uses a bioeconomic modelling approach to show that for some optimal allocation of the mopane forest stock, the restrictive harvest period policy advocated by community leaders may not lead to sustainable harvesting of the worm.
Tanzania recognises the potential of international tourism in accelerating socio-economic development, particularly as a supplier of foreign exchange, investment and employment. This paper investigates the factors affecting international tourism demand for Tanzania.

This paper investigates the factors affecting international tourism demand for Tanzania.
The authors studied the potential tradeoff between countries’ investments in mitigation versus adaptation to climate change. Mitigating greenhouse gases may be a public good, but adaptation to climate change is a private good, benefiting only the country or individual.
Studies have shown differences in cooperative behavior across countries and in the use of (and reaction to) a norm enforcement mechanism in cross-cultural studies.
This paper analyses the development and economic functioning of the car guards industry with the understanding that the market exhibits quasipublic good characteristics.
This paper investigates whether South African households and small businesses can take advantage of the country's substantial wind resources to produce their own power from small- scale wind turbines in a viable way.
This paper deals with bioprospecting defined as the purposeful search for natural compounds undertaken by pharmaceutical or biotechnology firms to find leads necessary for the development of new drugs.
The paper develops a dynamic discrete choice model of a self-interested and unchecked ruler making decisions regarding the development of a resource rich country.
This chapter provides a case study of the use of choice modelling method in irrigation water supply policy and management in Portugal.
One of the most pressing problems faced by the Tunisian farmers and authorities is the inexorable decline of the water table over the past twenty years due to the over-exploitation of the groundwater. This study is an attempt to find how this issue can be resolved through collective action.
This paper analyses differences in the choice of health care facility by ill individuals in HIV/AIDS-affected households in the Free State province of South Africa.
The aim of this working paper is to investigate the optimal regulatory routes from a competition and public interest point of view for the South African water industry.
This thesis consists of six papers, related to artifactual field experiments, conducted in South Africa. The main focus of the thesis is the effect of different forms of heterogeneity on cooperation and punishment within groups.
By making use of national historical data and statistical analysis, this paper argues that community-based wildlife conservation is a feasible hedge asset for agricultural production in rural Zimbabwe.
While many factors might affect biodiversity conservation, the use of economic incentives is argued to be potentially one of the most effective mechanisms for mainstreaming biodiversityconservation in bioregions. Institutions are singled out as one important class of socio-economic arrangements directly associated with economic incentives.
The efficient governance of information-production is analysed in the context of the bio-technology industry. Here primary R&D generates pure abstract information on the nature of biological solution concepts, while secondary R&D generates commercial products marketable to consumers.
The Economics of Climate Change: Putting a Price on Carbon
Using South Africa’s hake and rock lobster fisheries, the authors argue the need for satellite accounts of South Africa’s commercial fisheries.
This publication provides advice on how to approach wetland valuation studies in terms of methodological rigour, breadth and depth of the analsys, according to their application, and provides detailed guidelines for valuation methods used for different types of value.
This publication is a compilation of five wetland valuation case studies carried out on different provisioning, regulating and cultural services and at different scales in South Africa in Lesotho.
This publication provides an explanation of the social benefits provided by wetlands in rural and urban areas, and a logical and straightforward way in which to quantify and compare the importance of individual wetlands in terms of their livelihood contribution.
This publication provides a comprehensive review of the nature of the services provided by wetlands, how they are measured and valued, giving case study examples from around the world.
If communities living adjacent to the elephant see it as a burden, then they cannot be its stewards. To assess their valuation of it, a contingent valuation method study was conducted for one CAMPFIRE district in Zimbabwe.
This paper uses the autoregressive distributed lag (ARDL) approach to cointegration to estimate the coefficients of the determinants of international tourism demand for Zimbabwe for the period 1998 to 2005. The results show that taste formation, transport costs, changes in global income and certain specific events have a significant impact on international tourism demand.
This paper evaluates the impact of credit availability on communal and commercial sector maize output in Zimbabwe. This is important given the increased use of concessionary credit for agriculture as a policy strategy to increase agricultural output and food security, in response to the disruption caused by controversial land reform.
This paper uses relatively recent time series techniques on data spanning over different pricing regimes to estimate the aggregate agricultural supply response to price and non-price factors in Zimbabwe. The ARDL approach to cointegration employed here gives consistent estimates of supply response in the presence of regressor endogeneity and also permits the estimation of distinct estimates of both long-run and short-run elasticities when variables are not integrated of the same order.
The effects of stake size on cooperation and punishment are investigated using a public goods experiment.
Imbrasia Belina also known as the mopane worm, like other edible insects and caterpillars, is a vital source of protein to Southern African countries. The worms live and graze on mopane trees, which occupy agricultural land. With increasing commercialization of the worm, the management of the worm, which was hitherto organized as a common property resource, has degraded to a near open access.
The value of genetic resources for R&D is placed within the framework of discussions concerning sustainability. We assess the extent to which society is able to invest now in order to prepare for future risks and uncertainties in the arrival of biological problems.
This study focuses on a movement in methods of structuring that has been around for the past twenty years: socially responsible investing. The study focuses on France between 2001 and 2005 and a particular category of actors: asset managers who sell financial products presented as socially responsible on the French market.
This paper analyses the impact of income inequality on public good provision in an experimental setting. A sample of secondary school students were recruited to participate in a simple linear public goods game where income heterogeneity was introduced by providing participants with unequal token endowments.
In May 2003 South Africa introduced legislation intended to decrease plastic bag litter. It combined standards and price-based economic tools in an attempt to reduce the public's demand for plastic bags. This paper analyses the short term effects of the legislation on bag demand.
