Educating for our environment: an Australian experience

This paper examines how some of the principles of environmental education have been taken up in environmental strategies and activities in Victoria, Australia. The focus is upon the efforts of the State Government-funded Victorian Environmental Education Council (VEEC) to encourage the development of environmental education in sectors and organizations outside the formal education sector and not usually associated with either the environment or education. The relative success of initiatives fostered in marginalized community sectors and in the private industry sector are discussed. Following the abolition of the VEEC (late 1993) with a change of government, questions are raised about the sustainability of environmental reform agendas in the public political domain. In view of the fragility of sympathetic political environments, it is argued, that for environmentally sustainable development a broader commitment to social justice and social change must be fundamental to environmental education principles and processes to both include all sections of the community and, also, to actually change who makes decisions and how and where they are made.Jeannie Rea lectures in environmental policy and polities at Victoria University of Technology, Victoria, Australia.

Predicting community sensitivity to ozone, using Ellenberg Indicator values

This paper develops a regression-based model for predicting changes in biomass of individual species exposed to ozone (RS(p)), based on their Ellenberg Indicator values. The equation (RS(p)=1.805-0.118Light-0.135 square root Salinity) underpredicts observed sensitivity but has the advantage of widespread applicability to almost 3000 European species. The model was applied to grassland communities to develop two further predictive tools. The first tool, percentage change in biomass (ORI%) was tested on data from a field-based ozone exposure experiment and predicted a 27% decrease in biomass over 5 years compared with an observed decrease of 23%. The second tool, an index of community sensitivity to ozone (CORI), was applied to 48 grassland communities and suggests that community sensitivity to ozone is primarily species-driven. A repeat-sampling routine showed that nine species were the minimum requirement to estimate CORI within 5%.     

The future of water in Australia: The potential effects of climate change and ozone depletion on Australian water quality,quantity and treatability

Water is a resource that is essential for all life on Earth. An exponentially growing human population, in addition to unprecedented industrial and technological development, threaten the availability and quality of this resource. Climate change and ozone depletion are two major environmental problems facing mankind today. These problems have the potential to further strain currently available freshwater resources. Recent research has shown that climate change and ozone depletion are linked phenomena and their interaction exacerbates their impact. Changes in precipitation, surface runoff, solar UV radiation, temperatures, and evaporation are some of the predicted outcomes of climate change and ozone depletion. They influence the biogeochemical cycles and aquatic ecosystems in lakes and rivers, and alter the character of natural organic matter (NOM) and, consequently, they have the potential to affect the quality, quantity and treatability of our water resources. Given these uncertainties, and the need to mitigate the consequences of climate change and ozone depletion, the issues of changing water quality, quantity and treatability cannot be ignored by Australian governments and water utilities.
