Identify and value ecosystem services found on the land belonging to the Khomani San – inside and outside the Kgalagadi Transfrontier Park. Our study aims to estimate the economic value (benefits) of protecting a dryland ecosystem in the park.
The overall objective of the study is to provide the value of time estimates for automobile users on a congested road using a stated preference survey. The purpose of this study is to obtain the public preferences for time savings on a congested road, which we believe could provide important policy inputs for ongoing congestion pricing discussions in Beijing.
Open access post-harvest grazing is widespread in mixed crop-livestock systems. This discourages conservation agriculture, which depends on keeping the soil surface covered with crop residues. One way to reduce open access grazing is through restricting communal grazing access to allow rights of exclusion, while simultaneously improving the production of livestock feeds.
Ocean acidification (OA) is one of the largest emerging and significant environmental threats for the aquaculture industry, jeopardizing its role as an alternative for supporting food security. Moreover, market conditions, characterized by price volatility and low value-added products, could exacerbate the industry’s vulnerability to OA.
Good Solid Waste Management (SWM) practices are indispensable for maintaining quality environment and the health of urban dwellers in most developing countries, like Ethiopia. However, for successful implementation of adequate SWM options, households’ preferences and their Willingness to Pay (WTP) should be taken in to consideration. The main aim of this study was to analyse the preferences of households’ and estimate the WTP for improved SWM service attributes in the form of money income and labor effort using choice experiment approach.
Do Environmental Protection Agency (EPA) bureaucrats represent the general public or are they more in line with an interest group? We study preferences for environmental policy using a choice experiment (CE) on three populations; the general public, Swedish EPA bureaucrats, and recreational anglers. We also test for existence of multiple preference orderings: Half of the respondents were asked to choose the alternatives that best corresponded with their opinion, and the other half was asked to take the role of a policy-maker and make recommendations for environmental policy. The SEPA bureaucrats have the highest marginal willingness to pay (MWTP) to improve environmental quality. Differences in MWTP are robust and not due to differences in socio-economic characteristics across the populations. We only found weak evidence of multiple preference orderings.
Ecosystem-based fisheries management (EBFM) is an important complement to existing fisheries management approaches to maintain ecosystem health and function; to translate goals and aspirations for sustainability into operational objectives, the preferences of the fishing communities should be considered for successful implementation of EBFM. This study analysed the preferences of the fishing community for alternative EBFM developments for Lake Naivasha, Kenya, and estimated the willingness to pay, using a choice experiment approach.
With considerable focus on ecotourism's potential to contribute to conservation, it is increasingly important to understand the implications of ecological information in triggering sustainability-relevant attitudes and actions. This study assesses whether people who have ecological information regarding the negative impact of their recreational behavior on penguins’ stress will choose to remain farther away from the penguins to avoid that impact although this option will reduce the personal benefits of their tourism experience.
Biodiversity plays a key role in sustaining the functioning of ecosystems and thus in the provision of ecosystem services. A great deal of biodiversity is to be found in private forests, thus the way in which these forests are managed has major implications for biodiversity.
When designing choice experiments for nonmarket valuation the role of the price attribute is of major importance. In the energy sector the uncertainty of future direction of changes in prices makes it difficult to include an adequate price vector in the design.
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.
Because the effectiveness of payment for ecosystem services (PES) programs depends on landowners’ engagement, understanding the relationship between the type of payment and participation is a key issue. This paper reports on a choice experiment that quantifies landowners’ preferences for cash and educational in-kind payment. The main results indicate a positive correlation between participation in a PES contract and the magnitude of the cash payment, while participation seems uncorrelated with the magnitude of the educational in-kind payment.
In the contingent valuation method, both the goods being valued and the payment vehicles used to value them are mostly hypothetical. However, although numerous studies have examined the impact of experience with the good on the willingness to pay, less attention has been given to experience with the payment vehicles.
