Spatial Analysis of Ecosystem Disservice via Disamenity of Mosquitoes – A Case Study in Nagoya City, Japan

Abstract

Nature provides many benefits to human society, known as ecosystem services (ESs), and also has negative impacts on human society, known as ecosystem disservices (EDSs). Mosquitoes contribute to EDSs, such as the risk of disease, the disamenity of mosquito bites. The purpose of this study was to understand the factors of EDSs caused by mosquitoes, employing a case study in Nagoya City, Japan. Mosquitoes were collected by CDC (Center for Disease Control) CO₂-baited traps. Also a questionnaire survey of Nagoya citizens was conducted to assess the disamenity level of mosquitoes. Many variables, such as land use type, were developed by geographical information system (GIS). Statistical analyses were conducted to identify the main factors of mosquito abundance and disamenity. Important factors were identified for both mosquito abundance and its disamenity. Further studies, including multi-point trap surveys and more detailed spatial studies, are required to elucidate these aspects.
