Species Imperilment on the Global Scale: Empirical evidences of economic causes
(), Monica Campos, Lena Gustafsson and Katarina Elofsson
Abstract: Economic factors contribute to biodiversity directly
through activities such as pollution and land use, and indirectly by
affecting preferences and institutional capabilities of implementing
mitigation measures. This paper tests the explanatory power of these
different mechanisms on threats to biodiversity on a global scale.
Econometric analyses are performed with invasive species, land use,
climate, economic prosperity, corruption, and spatial autocorrelation as
explanatory variables. This is carried out for all taxonomic groups and
separately for mammals, birds, plants, amphibians, and reptiles. Different
models are tested and robust results appear for detrimental effects of
invasive species, pollution, and high average temperature. Results also
indicate that economic prosperity and institutional capacity do not act as
curbing factors in isolation, but instead together which points out the
need for sufficient levels of both prosperity and institutional capability
in order to preserve biodiversity. These impacts are significant for all
taxonomic groups but of different magnitude. Plants show the highest
relative response to several factors and mammals the lowest.
