Assessing the impact of land-cover changes on ecosystem services: A first step toward integrative planning in Bordeaux, France

Abstract

International audienceThe quantification and integration of ecosystem services (ES) into urban planning decisions is becoming increasingly important. However, studies that quantify and analyze the impacts in terms of ES changes are still scarce. We analyzed multiple ES provided by the landscape of the Urban Community of Bordeaux (CUB), in France, between 1990 and 2006 as a result of land use and cover change (LUCC) with Corine Land Cover and other open data. These ES were selected with the help of local stakeholders and were calculated using a spatially explicit modeling approach with InVEST and own-produced models. It was found that all ES, except erosion regulation, have decreased as a consequence of LUCC. Results also suggest that LUCC change decisions which do not consider policy measures for ES protection tend to generate land use patterns providing lower levels of ES. This spatial explicit approach to ES modeling enables an informed discussion with stakeholders and may be used to effectively implement, monitor, and communicate future planning policies

Ecosystem services and biodiversity trends in Mozambique as a consequence of land cover change

“…Therefore, and considering the data availability, the selected ES indicators for modeling included water yield, water quality, sediment retention, carbon storage, and biodiversity. These indicators have been used successfully in other studies (Bhagabati et al 2012;Bai et al 2013;Leh et al 2013;Cabral et al 2016). Table 2 shows the ES and respective ES indicators (units) used in the current study.…”

“…InVEST is a free and open model, has low data requirements, and has demonstrated its usefulness in different study areas (Nelson et al 2009;Goldstein et al 2012;Delphin et al 2013;Geneletti 2013;Leh et al 2013;Cabral et al 2016;Jiang et al 2016;Posner et al 2016). Thus, the main goal of this study is to assess the impact of LCC on multiple ES and biodiversity of this country.…”

Relationships Between Ecosystem Services: Comparing Methods for Assessing Tradeoffs and Synergies

“…InVEST consists of a suite of spatially-explicit models that use LULC maps, biophysical and economic data to quantify and map various ES provided by landscape in biophysical or economic terms (Cabral et al, 2016;Levrel et al, 2017;Nelson et al, 2009;Tallis and Polasky, 2009) For static spatial correlations, we calculated the Pearson correlation coefficients between pairs of ES (sub-watershed level) at the four dates. For the temporal correlations, we calculated the variations of each ES between two consecutive dates (1986-1996, 1996-2001, 2001-2008) and between the start and end of the whole period studied We graphically represented the production possibility set of each pair of ES by plotting ES values in all landscape configurations (four observed and 32 simulated) against one another.…”

Urban Sprawl Detection Using Remotely Sensed Data: A Case of Chennai, Tamilnadu

“…The expansion of cities causes urban sprawl, characterized by the extension of settlements with the decrease of agriculture, water bodies, and forest land. Studies on urban sprawl are necessary as they support different fields of science such as transport planning, landscape architecture studies, urban planning, land-use planning, economics, and ecosystem services [4].…”

“…The uncontrolled urban sprawl in Chennai city is having negative consequences regarding air pollution, housing, overcrowding, encroachment, slums, disposal of waste, increasing settlements, water availability, water pollution, and sewage [11]. The uncontrolled urban sprawl also leads to various environmental impacts, such as higher energy utilization, disturbance of species diversity, flood risk, and ecosystem fragmentation [4]. Predicting urban growth and associated impacts on ecosystem services will contribute to better urban planning with the design of eco-friendly cities that avoid the major negative consequences of urban sprawl [1,12].…”
