A contingent valuation study was conducted to estimate tourists' willingness to pay (WTP) for an environmental fee aimed at enhancing nature protection in Aruba. Stay-Over tourists (staying at least one night) and cruise tourists (visiting without staying overnight) were surveyed. A random sample was used, stratified by nationality for stay-over tourists and a random sample for cruise tourists. Surveys were conducted in person at Aruba's exit points, such as airports and ports. Binomial logistic regression models were applied to assess the likelihood that tourists will contribute to Aruba's conservation, and simple linear regression models were used to estimate WTP.A higher percentage of cruise tourists (52.7%) compared to Stay-Over tourists (47.3%) indicated that they are willing to pay for nature conservation; however, Stay-Over tourists have a higher WTP per visit. This contributes t...

Lima Metropolitana cuenta con muy pocas estaciones meteorológicas, lo cual dificulta obtener temperaturas de la superficie en forma distribuida e imposibilita la identificación de las Islas de Calor (IC). Sin embargo, mediante el uso de imágenes del satélite LANDSAT 5TM, pudimos obtener la temperatura de superficie e identificar las IC, analizando para ello seis eventos que fueron corregidos por emisividad.Los eventos analizados corresponden a los registrados a las 10:00 a.m. en las siguientes fechas: 11 de febrero del 2008, 15 de abril del 2008, 1 de mayo del 2008, 2 de abril del 2009, 31 de enero del 2010 y 7 de marzo del 2011. Asimismo, se obtuvieron datos de temperatura del aire de 6 estaciones meteorológicas para estos eventos.Se encontró islas de calor negativas durante la mañana principalmente en las zonas no urbanas. Se ubicaron 5 islas de calor urbanas, 7 islas en zonas i...

The objective study was to map cultural ecosystem services (aesthetic appreciation and recreation) in Aruba, from tourists’ point of view. The Public participation Geographical Information System was used. Aruba has two types of visitors: Stay-Over visitors (who spend at least one night in Aruba) and Cruise visitors (those who do not spend the night). Data was obtained by interviewing tourists using Public Participatory Geographic Information System in October and November 2016 and March 2017. The data was used to determine tourists’ aesthetic and recreational hot spots (areas with an abundance of events) and then to compare Cruise visitors’ hot spots with Stay-Over visitors’ hot spots. Then, tourists’ hot spots were compared with the local resident’s hot spots. The residents’ data was obtained from a previous study. Tourists and local citizens indicate that the California ...
