Submitted by Luat Do on
EfD Authors:

Coral reefs in Nha Trang City have been threatened by human activities such as use of dynamite, illegal harvesting, shipping, and pollution from the nearby port development project. How much recreational benefit from coral reefs is lost if these activities are not held in check? Using travel cost method, this study estimated the recreational value of coral reefs in Nha Trang to be VND 259.8 billion (USD18.3 million) annually, of which Hon Mun’s consumer surplus was estimated to be VND 45.4 billion (USD3.2 million).

AbstractThe ocean, which regulates climate and supports vital ecosystem services, is crucial to our Earth system and livelihoods. Yet, it is threatened by anthropogenic pressures and climate change. A healthy ocean that supports a sustainable ocean economy requires adequate financing vehicles that generate, invest, align, and account for financial capital to achieve sustained ocean health and governance.

Estimating discount rates for environmental goods: Are People’s responses inadequate to frequency of payments?

Submitted by Cristóbal Vásquez on

Most stated preference studies estimate discount rates using a split-sample approach. Each sample faces a different payment frequency (for instance, 1, 5, 10) together with a randomly assigned bid vector; both the frequency of payments and the bid are fixed for a specific individual. This paper evaluates whether allowing respondents to choose their preferred payment frequency affects the estimated discount rate.

Fisheries benefits of a marine protected area with endogenous fishing efforts – A bioeconomic analysis

Submitted by Tali Hoffman on
EfD Authors:

The study assesses the conservation and fisheries benefits of the Blue Bay Marine Park in Mauritius. It addresses the question - are the higher catch rates near the Park a result of population spillovers or of reduced fishing effort in those waters due to site-specific attributes? There is no data on catches and fishing effort prior to the reserve's establishment; a bioeconomic model is used to separate the effects of spillover and effort redistribution on catch rates in waters next to the Marine Park.

EFFECTS OF FISH ATTRIBUTES ON LANDING PRICE IN SELECTED DISTRICTS ALONG LAKE VICTORIA, TANZANIA

Submitted by Salvatory Macha on
EfD Authors:

 Studies around Lake Victoria documented various challenges hindering higher landing prices among artisanal fishers associated with varying attributes of fish. However, determination of the effects of fish attributes on landing price, which is potential to the wellbeing of fishermen, remains undisclosed during the landing of the fish harvest to the landing sites. This paper employed cross-section data from 300 fishermen to examine the effects of fish attributes on fish prices of the selected fish species.
