A valuation scenario was designed using a contingent-valuation approach and presented to decision makers in business firms in Kenya’s Lake Naivasha basin to test how applicable a water fund might be as a potential financing mechanism for a payment for water-related ecosystem services scheme. The findings indicate that measuring a firm’s willingness to invest in ecosystem services could help determine whether a firm would invest and engage with other stakeholders to pool their investments in ecosystem services.

We specify a model to analyze the participation and supply decisions of coastal producers performing with mussel seed uptake.

In this study, we measure the value of sanitary restrictions in terms of forgone profits. For this, we model the short-run trade-off between biosecurity and profits in the aquaculture industry.

The amenity value of the Kogelberg Coast of South Africa was estimated on the basis of a survey of users, property data and park visitor statistics, as well as spatial data on coastal features, development and recreational activities. In addition to the permanent population of about 13 000, visitors spend an estimated 4.3 to 5.3 million visitor days per year, of which holiday home owners, other overnight visitors and day visitors account for about 22 percent, 56 percent and 21 percent, respectively. Coastal activities contributed 71 percent to all users’ enjoyment of the area.

Recreational angling in South Africa is not well monitored, even though recreational fishing contributes to over-exploitation of line fish stocks. This is because authorities don’t have the resources or political will to patrol the entire coastline. This study shows that anglers tend to seek out fishing spots where they are likely to catch the most fish. If enforcement officials target these ‘hotspots’, they can monitor whether anglers are adhering to their permit conditions, which limit the number and size of fish that they are allowed to catch. 

We explore the effects of different enforcement mechanisms, including formal (external), informal (local), and both together, on individual compliance behavior under a system of territorial use rights in fisheries (TURFs).

Se estudia la evolución de la actividad acuícola en Chile y el impacto de los cambios regulatorios sobre las decisiones de localización de los centros de cultivo. Este estudio considera un análisis descriptivo del desarrollo espacio-temporal de los centros de cultivo. Enseguida, utilizando un panel de datos, se estimó un modelo de elección de sitios con el objetivo de explorar los factores determinantes de la elección de ubicación de los centros acuícolas. Los resultados del análisis sugieren la existencia de un claro patrón de desarrollo espacio-temporal de la acuicultura en Chile.

Using numerical simulations of the mixed common sardine and anchovy fishery of central-southern Chile, we study the effects of the distribution of administrative costs between the government and the fishing industry in an individual transferable quota system. Consistent with recent theoretical results, we find that the level and distribution of the administrative costs between the public and private sector affects the period-by-period equilibrium quota price and number of active vessels.

We study the compliance behavior of artisanal fishermen in central-southern Chile. Our empirical analysis explores the role of individual morality, perception of legitimacy, and peer effects as determinant factors in the decision to violate regulations. We control for potential simultaneity bias in the peer effects variable.

Our results find evidence that moral standing, peer effects, and legitimacy considerations are important for fishermen’s compliance decisions. Policy implications to improve compliance with regulations in artisanal fisheries are discussed.
