Introduction

The terrestrial module consists of 6 impact modules each quantified in terms of the mean species abundance (MSA). The impact modules are:

• impact of eradication or modification of natural habitat through land-use;
• impact of an increase in global mean temperature induced by climate change;
• impact of eutrophication induced by atmospheric nitrogen deposition;
• impact of the disturbance of natural habitat through the proximity of infrastructure;
• impact of the fragmentation of natural habitat by both land-use and infrastructure;
• impact of human encroachment, facilitated through access provided by land-use.

A combined impact effect on biodiversity is computed by multiplying the MSA values of the individual impacts. In this calculation it is assumed that the direct land-use impacts of agriculture and urban areas take precedence over all other impacts.
