Assessing benefit transfer for the valuation of ecosystem services

Journal Articles & Books
Diciembre, 2009

The valuation of ecosystem services can play an important role in conservation planning and ecosystem‐based management. Unfortunately, gathering primary, site‐specific data is costly. As a result, a popular alternate method is to conduct a “benefit transfer” (applying economic value estimates from one location to a similar site in another location). Among the potential pitfalls of such an approach, the correspondence (or lack thereof) between the locations is probably the most important for evaluating the probable validity of the benefit transfer.

Mapping potential carbon and timber losses from hurricanes using a decision tree and ecosystem services driver model

Journal Articles & Books
Diciembre, 2013

Information on the effect of direct drivers such as hurricanes on ecosystem services is relevant to landowners and policy makers due to predicted effects from climate change. We identified forest damage risk zones due to hurricanes and estimated the potential loss of 2 key ecosystem services: aboveground carbon storage and timber volume.

[Investigation of natural grasslands in Latvia]

Conference Papers & Reports
Diciembre, 2005
Letonia

Investigations of grasslands in Latvia started at the beginning of the 20ty century. One of the main goals was investigation of vegetation classification. In Latvia typology of natural grasslands in several investigation periods is based on different criterions: (1) economic typology, (2) grasslands vegetation physionomic classification according to dominant method, (3) classification of flora according to Braun-Blanquet method.

effect of urban heat island on Izmir’s city ecosystem and climate

Journal Articles & Books
Diciembre, 2015

Depending on the researches done on urban landscapes, it is found that the heat island intensity caused by the activities in any city has some impact on the ecosystem of the region and on the regional climate. Urban areas located in arid and semiarid lands somehow represent heat increase when it is compared with the heat in the surrounding rural areas. Thus, cities located amid forested and temperate climate regions show moderate temperatures. The impervious surfaces let the rainfall leave the city lands faster than undeveloped areas.

Re-evaluation of the role of the grey partridge Perdix perdix as a disperser of arable weed seeds

Polonia

The endozoochorous dispersal of weed seeds, mediated by birds and without any adaptation to frugivory, has been studied very rarely. We studied the endozoochorous dispersal of viable seeds by the grey partridge Perdix perdix in agricultural landscape. We assessed the content of intact seeds in 609 grey partridge droppings coming from 21 sampling sites in Poland that included three land-cover types (winter cereals, winter oil-seed rape and stubble fields). We found 159 intact seeds of 13 plant species. Most of them are classified as plants without any evolved adaptations to dispersal.

Hydrological benefits in the context of Brazilian environmental services program

Journal Articles & Books
Diciembre, 2013

The Brazilian program of payment for environmental services (PES) is based on ranges of potential erosion decrease (ED) from soil and water conservation proposals estimated from the Universal Soil Loss Equation. Changes in land use and land cover (LULC) result in many alterations of the basin water balance. Therefore, to contribute to the methodological development of Brazilian PES, this paper proposes a quantification of hydrological benefits based on conservation measures.

Morphological analysis of green infrastructure in the Seoul metropolitan area, South Korea

Journal Articles & Books
Diciembre, 2015
República de Corea

The purpose of this study is to understand changes in green infrastructure (GI) in the Seoul metropolitan area, South Korea, focusing on the critical GI components of hubs and links. We applied a morphological analysis tool, morphological spatial pattern analysis (MSPA), to explore GI in the Seoul metropolitan area. For input data to run MSPA, we used 30-m pixel-sized land cover data of 2000 and 2009 provided by the Ministry of Environment of Korea. Land cover data are used as foundational information for GI network mapping.

Numerical simulation of the impact of land cover change on regional climate in China

Journal Articles & Books
Diciembre, 2014
China

Land use and land cover change (LUCC) can modify the physical and thermodynamic characteristics of the land surface, including surface roughness, albedo, and vegetation fraction, among others. These direct changes can result in a series of impacts on regional climate. In this paper, the simulated results over China under the scenario of LUCC using weather research and forecasting model are presented. The period for the simulation is from December 2006 to December 2011. Two experiments are initialized by the LUCC datasets derived from the MODIS data of 2001 and 2008, respectively.

Modern influences on chironomid distribution in western Ireland: potential for palaeoenvironmental reconstruction

Journal Articles & Books
Diciembre, 2014
Irlanda

Ireland provides a unique setting for the study of past climates, as its climate is dominated by westerly airflow from the North Atlantic and readily responsive to changes in North Atlantic circulation patterns. Although there has been substantial research on Ireland’s past environments, quantitative palaeolimnological research, especially chironomid-based research, has been lacking. In order to further develop chironomid-based palaeolimnological investigations, a calibration set was constructed to determine the dominant environmental controls on modern chironomids in western Ireland.

Mapping and Identification of Homegardens as a Component of the Trees Outside Forests Using Remote Sensing and Geographic Information System

Journal Articles & Books
Diciembre, 2014
India

The homegardens represent an important component of the trees outside forests (TOF) in the rural ecosystem which fulfill a range of subsistence and economic needs besides providing many environmental services. The present work was focused on the identification and mapping of rural homegardens as a component of the trees outside forests in the larger landscape of the three districts—Cachar, Hailakandi and Karimganj, of Barak Valley, Assam, northeast India.

evolution of two great Mediterranean Deltas: Remote sensing to visualize the evolution of habitats and land use in the Gediz and Rhone Deltas

Land cover and land cover change, both in time and space, were analyzed in the Gediz Delta (Turkey) and the Rhone Delta (Camargue, France) to determine the evolution of two great deltas in the Mediterranean basin. Geographical Information Systems and remote sensing were used to estimate the impact of land use changes on habitats over a 35 year period from 1975 to 2010.
