AERU AGRICULTURE & ENVIRONMENT RESEARCH UNIT
 

Development of new environmental assessment techniques

There is always potential to improve how we assess the effects and impacts that arise from agricultural practices and land use. As our knowledge and technology has grown, so has our capability to assess environmental effects and impacts. Over two decades AERU have developed and pioneered numerous novel techniques to enhance environmental assessments in the agricultural and land use sector, both at the farm and policy levels.

Skills and services encompass the following:

  • Development of indicators and metrics
  • Development of aggregation and synthesise techniques
  • Development of tools and techniques to aid communication and knowledge transfer
