El resultado es un deterioro profundo de los ciclos de nutrientes y energía, disminución en la diversidad de especies y aumento de especies tolerantes a la contaminación (Ramírez et al, 2002;Cvetkovic & Chow-Fraser, 2011); lo que afecta principalmente servicios ecosistémicos asociados al ciclo hidrológico y recreativos (Barbosa & Villagra, 2015).…”

RESUMENLa urbanización en Concepción metropolitano (36°S) en las últimas décadas ha impactado áreas de valor ecológico, tales como humedales y lagunas. Aquí analizamos la perturbación de parámetros de biodiversidad en seis humedales urbanos, mediante la exploración y uso de indicadores. Se proponen tres indicadores: naturalidad y riqueza de macrolepidópteros y plantas, los que se evalúan mediante modelos de regresión múltiple. Los resultados indican que los humedales con menor grado de perturbación antrópica se encuentran ubicados dentro de una reserva protegida y rodeados de una matriz de paisaje seminatural; mientras que los más perturbados están más próximos a la urbanización. Además, la riqueza de macrolepidópteros se ve más afectada por la distancia a carreteras, en cambio la riqueza de plantas por la densidad de viviendas. Se genera una herramienta para la evaluación de efectos de la urbanización en humedales urbanos.Palabras clave: Humedales, Urbanización, Biodiversidad, Naturalidad ABSTRACTUrbanization of the Metropolitan region of Concepción (36°S) in the last decades has impacted on the ecological value of areas such as wetlands and lagoons. Here, we analyse the disturbance to biodiversity indicators in six urban wetlands. Three measures are proposed: a naturalness indicator and two Macrolepidoptera plant indicators of species richness. Multiple regression models were developed for the assessment of indicators. Results show that the wetlands with the lowest degree of human interference are located in a protected area and surrounded by a matrix of semi-natural landscapes, whereas the more disturbed wetlands are those closer to areas of urbanization. Results indicate that macrolepidopterans richness is more affected by the distance to roads, in contrast with the richness of plants, which is affected by housing density. We generated a tool for the assessment of urbanization effects in urban wetlands.

“…It is, therefore, important to recover the damaged ecosystem, such as wetlands, estuaries, sand dunes, and landscapes, which have high values for sustainable coastal tourism. Especially, coastal wetland ecosystems have been suffering from serious degradation, alteration or loss due to intense anthropogenic activities (i.e., pollution and drainage) [34][35][36] and, thus, coastal wetlands are listed amongst the most heavily damaged of natural ecosystems worldwide [37]. Habitat management is particularly important to the coastal zones of Taiwan to protect natural habitats from the threat of erosion [38].…”

Performance Indicator Framework for Evaluation of Sustainable Tourism in the Taiwan Coastal Zone

et al. 2016

Abstract:Surrounded by the ocean, Taiwan has been increasingly developing coastal tourism projects. Concerns that negative impacts might be brought about by prosperous tourism have resulted in a recent focus on sustainable tourism. Sustainable tourism involves policies that acknowledge the interdependences among the environment, the community, and the economy. The goal of sustainable tourism is to enhance and protect the environment while satisfying basic human requirements, as well as those of the contemporary and future tourism industries to improve quality of life. On the other hand, unsustainable coastal tourism might undermine the natural environment and society, resulting in air, water, and soil pollution, wildlife habitat disruption, and changes of local community cultural characteristics. Therefore, performance evaluation of coastal tourism, using an indicator framework to facilitate sustainable development and enhance the effectiveness of coastal resources exploitation, is critical. Through a literature review and expert surveys using the methods of the fuzzy Delphi method (FDM) and the fuzzy analytic hierarchy process (FAHP), this study builds a performance indicator framework and identifies the key factors affecting the sustainable development of coastal tourism in Taiwan. The results can serve as a reference for the public sector to be used for the sustainable planning and development of coastal tourism.

“…This area is unique due to the low levels of agriculture and urban development that have allowed these wetlands to maintain the highest proportions of disturbance-intolerant fish and plant taxa within the Great Lakes coastal system [9,[13][14][15]. Although much of the shoreline was logged prior to the 1900s, easier access to inland logging sites and slow successional growth have prevented continuous logging along the shoreline in the past century.…”

“…Lack of information along the shore and in the surrounding islands of eastern Georgian Bay is a serious concern because this region holds some of the most pristine coastal marshes in the entire Great Lakes basin [9,13]. This area is unique due to the low levels of agriculture and urban development that have allowed these wetlands to maintain the highest proportions of disturbance-intolerant fish and plant taxa within the Great Lakes coastal system [9,[13][14][15].…”

“…These marshes provide many important ecosystem services including water purification, nutrient sequestration, and shoreline buffering [1,3], as well as important feeding and nursery habitat for a wide variety of organisms including fish, birds, invertebrates, mammals, and reptiles [5][6][7]. In Ontario, majority of these wetlands have been lost or degraded as a result of human disturbance [8], except in the eastern and northern shore of Georgian Bay, where they are mostly in relatively pristine condition [9].…”

Coastal wetlands of eastern Georgian Bay provide critical habitat for a variety of wildlife, especially spawning and nursery habitat for Great Lakes fishes. Although the eastern shoreline has been designated a World Biosphere Reserve by UNESCO, a complete inventory is lacking. Prior effort by the Great Lakes Coastal Wetland Consortium (GLCWC) was unable to fully identify coastal wetland habitat in eastern Georgian Bay due to limited data coverage. Here we outline the methodology, analyses, and applications of the McMaster Coastal Wetland Inventory (MCWI) created from a comprehensive collection of satellite imagery from 2002–2008. Wetlands were manually delineated in a GIS as two broad habitat types: coastal marsh and upstream wetland. Coastal marsh was further subdivided into low marsh (LM; permanently inundated) and high marsh (HM; seasonally inundated) habitat. Within the coastal zone of eastern and northern Georgian Bay there are 12629 distinct wetland units comprised of 5376 ha of LM, 3298 ha of HM and 8676 ha of upstream habitat. The MCWI identifies greater total wetland area within the coastal zone than does the GLCWC inventory (17350 ha versus 3659 ha resp.). The MCWI provides the most current and comprehensive inventory of coastal wetlands in eastern Georgian Bay.
