Recreational and conservative valuation of Bien Ho landscape

Abstract

Bien Ho is one of the volcanic landscapes showing lava eruptions that occurred millions of years ago. It is a symbol of the volcanic landscapes in the Tay Nguyen, Vietnam, which keeps a lot of values. This article aimed to quantify recreational and conservative values. The travel cost and contingent valuation method were used to estimate the recreational and conservative value (existence, bequest, and option value) of Bien Ho, respectively. The results indicated that the recreational and conservative value of Bien Ho volcanic landscape was 1,436.9 billion VND and 38.6 billion VND, respectively. The average willingness to pay in the contingent valuation method was 39,388 VND and depended only on ethnicity and age. The study used different populations to define survey samples according to each estimating method to improve the confident accuracy of the results.

Determination of Recreation and Tourism Use Value of Bozcaada by Travel Cost Analysis Methods

“…TCM and CVM are commonly used to estimate the recreational value of forest areas and national parks [30] and evaluate the value of non-market products or services through people's travel consumption behaviors [31]. TCM was used to determine the direct and indirect values as the recreational value of an island [32], of a lake [33,34], of beaches [35], of urban space [36], the value of fishing spot [37] and ecosystem of national parks [38,39]. With TCM, users of the park are questioned "how far they have traveled to visit the park", assuming that the economic value of the experience is the same for all users and the user traveling the longest distance to reach.…”

Efficiency of Using Tuned Mass Damper to Reduce Damage after Strong Earthquakes

“…It has been established that it is necessary to take damping into account when selecting the MD parameters [4,5]. At the beginning, the MD was applied in high-rise construction to reduce wind loads [6,7]. However, a number of high-rise buildings with the MD, for example, in Guangzhou and Taiwan, were erected in the earthquake prone areas to reduce both wind and seismic loads.…”
