The purpose of this study is to evaluate opportunities of the region of Su?la Lake located in Turkey for community-based ecotourism development that enable sustainable landscape and natural resource management as well as livelihood diversification. A participatory research approach was applied by participation of a diverse number of stakeholders (e.g. local communities, local and central governmental bodies and researchers). A set of participatory research tools (e.g. interviews and field surveys), SWOT analysis and the method of Ecotourism Opportunity Spectrum (ECOS) were used to collect and evaluate relevant data. The study consists of four sections. The first section focuses on SWOT analysis by which the advantages and disadvantages of the study area for ecotourism development were examined. In the second section, the most suitable villages for ecotourism development were examined by adapting the method of ECOS based on the 18 parameters by using 1–4 score system. Accordingly, the most suitable five villages for ecotourism development were determined. Major natural and cultural ecotourism resources (e.g. diversity of landforms, spectacular landscapes and traditional lifestyle) of the study area were examined in the third section. In the fourth section, the ecotourism-based livelihood and relevant core capitals were evaluated according to 1–4 score system for the five villages. We hope that the outcomes of this study can draw attention of planners and policymakers to the role of ecotourism for sustainable landscape and natural resource management as well as livelihood diversification in the region and elsewhere. 相似文献

A method has been developed for indirect determination of cyanide in environmental waters based on cloud point extraction (CPE), preconcentration and determination by flame atomic absorption spectrometry (FAAS). The method was based on reduction of Cu(II) to Cu(I) in the presence of cyanide and complexation of the produced Cu(I)(CN)2? with gallocyanin (GC+) as an ion-pairing reagent at pH 4.0, followed by its extraction into polyethyleneglycol mono-p-nonylphenylether (Ponpe 7.5). Selectivity was improved with the use of suitable masking agents. Various factors influencing separation and preconcentration of cyanide have been investigated, and conditions were optimized, allowing determination of cyanide in the range of up to 1.2 mg L?1 with a detection limit of 0.00045 mg L?1. The method has been applied to the determination of cyanide in environmental waters, the results being in agreement with those obtained by a reference method. 相似文献

Coastal erosion may be caused by natural causes as well as human factors. Karasu town of the city of Sakarya in Turkey which is a touristic region on the Black Sea coast has been experienced a drastic coastal erosion. In recent years, this erosion reached the threatening dimensions for the structures in the settlement. According to the temporal analyses of Landsat satellite images, the maximum erosion on the coastline was detected 100 m between 1987–2013. The results of the study show that the harbour construct on the Karasu coast has the major impact on this event. The secondary factor is that the amount of the sediment carried by the Sakarya River was decreased in time due to different reasons. To prevent the coastal erosion, a series of offshore breakwaters were planned after the failed application of groins on the coastline. In this study, temporal changes of the coastline are investigated by the Landsat satellite data and land surveys, possible reasons of the erosion are discussed and the solutions are proposed regarding the coastal structures. 相似文献

The aim of this study was to investigate the relationship between organizational climate and driver behaviours of professional drivers. The sample consisted of 230 male professional drivers. The participants completed a questionnaire including the Driver Behaviour Questionnaire (DBQ), Hofstede’s Organizational Culture Scale, and a background information form. Results of the factor analysis of Hofstede’s Organizational Culture Scale yielded two dimensions, which were named as “work orientation” and “employee consideration”. Analyses of Covariance (ANCOVA) revealed significant main and interaction effects of organizational climate on errors, and violations after controlling for the statistical effects of age, annual mileage and the organization types. Drivers with low scores of work orientation reported significantly higher frequencies of errors and violations than drivers with high scores of work orientation. It was also found that drivers with low scores of employee consideration reported higher frequencies of errors and violations than drivers with high scores of employee consideration. The effect of interaction between work orientation and employee consideration dimensions was only found on the frequencies of violations. 相似文献

The Mechanistic Indicators of Childhood Asthma (MICA) study in Detroit, Michigan introduced a participant-based approach to reduce the resource burden associated with collection of indoor and outdoor residential air sampling data. A subset of participants designated as MICA-Air conducted indoor and outdoor residential sampling of nitrogen dioxide (NO2), volatile organic compounds (VOCs), and polycyclic aromatic hydrocarbons (PAHs). This participant-based methodology was subsequently adapted for use in the Vanguard phase of the U.S. National Children’s Study. The current paper examines residential indoor and outdoor concentrations of these pollutant species among health study participants in Detroit, Michigan.Pollutants measured under MICA-Air agreed well with other studies and continuous monitoring data collected in Detroit. For example, NO2 and BTEX concentrations reported for other Detroit area monitoring were generally within 10–15% of indoor and outdoor concentrations measured in MICA-Air households. Outdoor NO2 concentrations were typically higher than indoor NO2 concentration among MICA-Air homes, with a median indoor/outdoor (I/O) ratio of 0.6 in homes that were not impacted by environmental tobacco smoke (ETS) during air sampling. Indoor concentrations generally exceeded outdoor concentrations for VOC and PAH species measured among non-ETS homes in the study. I/O ratios for BTEX species (benzene, toluene, ethylbenzene, and m/p- and o-xylene) ranged from 1.2 for benzene to 3.1 for toluene. Outdoor NO2 concentrations were approximately 4.5 ppb higher on weekdays versus weekends. As expected, I/O ratios pollutants were generally higher for homes impacted by ETS.These findings suggest that participant-based air sampling can provide a cost-effective alternative to technician-based approaches for assessing indoor and outdoor residential air pollution in community health studies. We also introduced a technique for estimating daily concentrations at each home by weighting 2- and 7-day integrated concentrations using continuous measurements from regulatory monitoring sites. This approach may be applied to estimate short-term daily or hourly pollutant concentrations in future health studies. 相似文献
