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.
This paper investigates and ranks a set of policy and technological interventions intended to reduce such health costs in the high population density areas of South Africa. The paper’s policy messages are that interventions should begin with households and that further industry controls are not yet justifiable in their present forms as these relate to the health care costs of such interventions.
If local communities living adjacent to the elephant see it as a burden, then they cannot be trusted to be its stewards. To assess their valuation of it, a CVM study was conducted for one CAMPFIRE district in Zimbabwe.
This report forms just one part of an integrated research effort on the BCLME fisheries being carried out by “The Consortium”. It is anticipated that, as the rest of the BCLME projects advance, new information relevant to this study will come to light. This is particularly true for project LMR/SE/03/03, for example. The Consortium wishes to reserve the right to update this marketing report if and when the relevant information becomes available.
This paper analyses participatory development through the lens of public goods theory. South Africa's Community Water Supply & Sanitation Programme is discussed as a case study.
We explore the effect of income inequality and peer punishment on voluntary provision of public goods in an experimental context. Our sample draws from nine fishing communities in South-Africa where high levels of inequality prevail.
A fishery run as a perfect monopoly seeking to maximize its profits over time, and secure in
its monopoly rights, will try to maximize the present value of its economic rents or profits over
time. To do this it will have to exploit the resource sustainably, keeping up the level of the
resource so as to keep up its catch per unit effort, and keep down its costs.
This paper formulates a bioeconomic model to analyze community incentives for wildlife management under benefit-sharing programs like the Communal Areas Management Programme for Indigenous Resources (CAMPFIRE) in Zimbabwe.
Natural environments in and around the South African coastal city of Durban provide goods and services to the national economy that amount to an estimated US$ 350 million (R 4.2 billion) each year.
Small-scale, community-managed hydro power schemes in remote rural Kenya function well if they are run by strong leaders, and have firm rules for how the scheme should be managed. When members of the mini-grid system know they will be disconnected from the grid for breaking those rules, they tend to cooperate more willingly.
For the average rural Kenyan, having a fully charged mobile phone isn't just a luxury that allows them to make phone calls. It’s a complete office for running their small businesses. So when people have access to an electricity source that allows them to keep their phone batteries charged, it means the entire local economy benefits.
The mountainous countryside in Kenya is ideally suited for small-scale hydro power plants, particularly for communities that are too far from the national electrical grid, or where the infrastructure and connection costs are too high. But the government of this East African country has not exploited its hydro power opportunities, something which environmental economist Mary Karumba hopes to change as she returns to government service after completing her doctoral studies in South Africa.
Having competitions between staff, appointing water-saving ‘champions’ in your office block, or recognising people for their efforts to use energy more sparingly: these are small but powerful ways that cities can encourage people to cut their water and electricity use. Now, behavioural economists at the University of Cape Town’s Environmental Policy Research Unit (EPRU) are about to embark on a three-year collaboration with Cape Town’s utility managers, to see how they can implement these ideas across the city, and get them written into municipal policy.
There are many ways for city utility departments to get people to voluntarily reduce their water use during a time of drought and water shortages. Some are positive, ‘carrot’ approaches; others might be ‘stick’ approaches to enforce certain behaviours. Now, the City of Cape Town is working with behavioural economists to find an evidence-based answer to which methods are most effective.
A team of behavioural economists has an important message for City of Cape Town’s water managers, who are currently implementing tight water restrictions after three years of drought in the region: if the city publicly praises individuals and households for their water saving efforts, this will get people to voluntarily contribute to even greater water-wise behaviour.
The people of Cape Town are being given a chance to tell city managers just how much they value the natural green spaces, manicured parks, sports fields, and street trees in their neighbourhoods. And what they say may help park authorities decide how to prioritise their spending, at a time when there is growing pressure to develop open green spaces for housing or business opportunities.
CAPE TOWN: The single most effective thing that South Africans can do to reduce their energy use related to heating water in their homes, is to switch off hot water cylinders half an hour before they are most likely to bath or shower. Those people who do switch their cylinders on and off during the day, as an energy saving measure, tend to turn them off after the geysers have refilled and reheated, which is wasteful of energy.
The South African node of the EfD network, the Environmental Economics Policy Research Unit at the University of Cape Town is working towards influencing South African policy in four key areas: climate change, biodiversity conservation, marine fisheries, and energy. One of the recent studies identified mixed farming as a crucial strategy to adapt to climate change, particularly for small farmers.
Development-focused eco-tourism partnerships between local communities and private enterprises are more likely to succeed if the communities living on the edge of protected areas are able to make direct links between the conservation of an area, and their own tangible benefits, the IUCN’s World Parks Congress heard recently.
On Wednesday 23 October, EPRU hosted the EfD Policy day at Commodore Hotel, Cape Town, South Africa. The policy day brought together policy makers from various governmental levels, practitioners, NGOs, international and national researchers.
In a brief interview with UNU-Wider Wisdom Akpalu, Associate Professor of Economics at SUNY-Farmingdale, NY, shares his view on the effectiveness of development knowledge aid and the impact of the “Gothenburg mafia” on Africa. A maybe misleading expression which relates to Wisdom himself and his former PhD colleagues who studied at the Environmental Economics Unit of the Economics Department at Gothenburg University.
Within the unique wetland area Mpumalanga Lake District lies the site of a proposed, and controversial, opencast coal mine, the Lusthof colliery. It will require a preliminary ‘set-aside’ of about 70 million South African rands.
Martine Visser and Jane Turpie advised the Legal Resource Centre and AWARD (NGOs working on behalf of the public and especially poor stakeholders such as farm workers)
ESKOM (national Energy Service Provider) has contracted Martine Visser, Grant Smith (masters student) and Steven Davies to do research on consumer understanding of billing practices.
In 1994 the Khomani San “bushmen” community successfully reclaimed land inside and outside the Kgalagadi Transfrontier Park. Yet despite ownership of a portion of land still part of the Kgalagadi Transfrontier Park, the Khomani San community has never directly benefited from tourism revenues from entrance fees.
Reporting to people about their own and the average consumption of electricity caused all kinds of households in suburbs of Cape Town to significantly reduce their electricity consumption. This is the conclusion of initial research results from EfD South Africa. Households in the middle income suburbs were the most responsive, followed by lower income suburbs. The upper income suburbs responded the least.
South Africa´s anchovy catch is predominantly used for fishmeal, despite the fact that a redirection of the resource towards human consumption could provide nutrition for the rural poor, create employment in coastal regions, and develop new opportunities in the fisheries industry. EfD researchers are sought out by the Marine and Coastal Management, Department of Environmental Affairs, to participate in an inter-disciplinary investigation of the feasibility of utilizing a resource portion of anchovy landings for direct human consumption.
