Abstract

Ekonomska vrijednost glavate želve (Caretta caretta (Lineaus 1758)) sastoji se od uporabne i neuporabne vrijednosti. Mjeri se novčanom vrijednosti koju su ispitanici spremni platiti kako bi sudjelovali u različitim ekoturističkim aktivnostima koje su održive i usmjerene na financiranje njihove zaštite. „Contingent valuation“ istraživanje provedeno je u Istri, Kvarneru i Primorskoj kako bi se procijenila njihova ekonomska vrijednost i potencijal za financiranje njihove zaštite. Istraživanje je također trebalo prikupiti podatke o podršci ispitanika za efikasnije provođenje mjera zaštite te smjernice za formiranje ciljanih obrazovnih programa u svrhu podizanja javne svijesti o važnosti očuvanja mora i morskih kornjača. Procjenjena neuporabna vrijednosti iznosi 2,3 milijuna € u Kvarneru i 3,4 milijuna € u Istri, dok je iznos uporabne vrijednosti bio isti u obje regije. Srednja vrijednost koju su ispitanici spremni platiti je 7,5 € za ulaznicu u centar za morske kornjače dok su za izlet promatranja morskih životinja u divljini spremni platiti 22 €. Uzorak iz Primorske regije nije bio reprezentativan te se rezultati ne smatraju valjanima. Iako je neuporabna vrijednost bila veća u Istri, Kvarner je pokazao veći potencijal za generiranje sredstava za zaštitu. U sve tri regije velika većina ispitanika (~90%) spremna je poduprijeti zaštitne mjere i formiranje zaštićenog područja u sjevernom Jadranu. Obrazovni programi trebali bi se usredotočiti na podizanje svijesti o važnosti sjevernog Jadrana kao staništa za morske kornjače, o morskim kornjačama kao indikatorskim i prioritetnim vrstama te o slučajnom ulovu i sudaru s brodovima kao uzrocima ugroženosti.

Abstract (english)

The economic value of loggerhead sea turtles (Caretta caretta (Lineaus 1758)) is made up of use and non-use values. It is measured by respondents' willingness to pay for participation in various sustainable ecotourism activities whose proceeds would be directed towards the conservation of loggerhead sea turtles. A contingent valuation survey was conducted in Istria, Kvarner and Primorska to estimate their economic value and to gauge its potential for generating funds for their conservation. The study also examines the respondents' support for the implementation of more effective measures of marine turtle protection and, consequently, what points the awareness-raising campaigns should focus on. The estimated non-use value was 2.3 million € in Kvarner and 3.4 million € in Istria, while the estimated use-value was the same in both regions. The median value of the amount of money the respondents were willing to pay was 7.5 € for an entrance ticket to a turtle center and 22 € for a ticket for a marine wildlife trip. The results derived from the Primorska region data aren't considered valid because the sample is not representative. Although in Istria loggerhead sea turtles have a higher value, the Kvarner region shows higher potential for generating funds for conservation. In all three regions, the great majority of respondents (~90%) were willing to support mitigation measures and the creation of a protected area in the North Adriatic. Educational campaigns should focus on raising awareness about the importance of northern Adriatic as a sea turtle habitat, of sea turtles as indicator and priority species, and the risks of bycatch and collision with speed boats.
