Achieving sustainability in agriculture: lessons from Australia

Abstract

The scientific evidence for environmental degradation is overwhelming however, it is sometimes difficult to translate this evidence into government and policy action and even more problematic to use it to generate behavioural change. The dynamics of scientific knowledge and the way it interacts with personal beliefs and social norms are complex and regard must always be had for the sometimes competing forces at work. Presently there are two crises enveloping the globe, one financial and the other environmental, which are forcing us to recognise the relationships between past and present human activities and future lives and landscapes. Humanity is presently facing relatively well-documented threats of climate change, land use conflict, desertification, extinctions, food, water and financial (in)security however we are still lacking some basic information about a critical part of the global system: ourselves. It is this gap which this study addressed, by inquiring into the environmental attitudes and behaviours of Australian farmers. In Australia the impacts of environmental change will be severe as it is already the driest inhabited continent on Earth and its high and unique biodiversity is especially susceptible to even minor perturbations in conditions. Impacts on food production will also be severe as approximately 60% of Australia's land surface is under agriculture and Australia exports two-thirds of what it produces.
