Sustainable land management enhances the environment while maintaining the economic profitabilityof businesses and social wellbeing of communities. This unit investigates the biophysical, economic and social components of land management systems, particularly agriculture, and the key issues, across a range of scales from the individual land holder or manager to the catchment or region, and finally to national and global level. Several detailed case studies, focusing on different land uses and contexts in Australia, will provide applied knowledge and understanding of key sustainability issues and current on-ground best-management practices and strategies.
