Quantifying and mapping multiple ecosystem services change in West Africa

摘要: Although ecosystem services have been identified to be declining over the previous decades, there is no clear methodology of evaluating impacts land use change on services. This paper presents a for quantifying and assessing changes in multiple ecosystems as result using Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model. The model was used map quantify biodiversity four Ghana Cote d’Ivoire 2000, 2005 2009 conditions: water yield, carbon storage, nutrient retention, sediment retention. study developed suite indices analyze status, spatial patterns On national scale, results show mix increases service (water N retention P Ghana, and, d’Ivoire), little (sediment yield d’Ivoire) decreases (biodiversity storage both countries) from 2000 2009. assessment illustrates that can employed by managers exploring management scenarios their implications change.
