Land, Water and Life
Emeritus Prof. Henry Nix AO
Visiting Fellow, Australian National University, ACT
Climate, terrain and soil are key determinants of which plants grow where and which plant assemblages are supported as well as primary constraints on human land use. A review and an update of a continental scale evaluation of potentially arable land in Australia provides a framework for assessment of future development threats to our native flora and fauna and the ecosystem processes that support them - and us.
The implications of rapidly rising global demands for food, fibre, fuel and fun and the associated accelerating rates of biodiversity loss are examined on a region by region basis.
Threatening processes include climate disruption that will impact on the climatic regimes to which our native flora and our established land uses are adapted. But the greatest threats will come from ever increasing intensification of land use to meet human demands. What will this mean for our ANPC objectives and our actions in the next 21 years?
