"Against a backdrop of advancing neoliberalism and globalisation, this timely book examines nine prominent Australians from diverse backgrounds - ʻglobal citizensʾ who have each enhanced public life through promoting universal values and human rights. The book charts over 50 years of campaigning, and espouses perennial causes such as peace, social justice, ecological sustainability and gender and racial equality. Ultimately, this inspiring volume sends a message of hope for Australian society and provides a benchmark for all proponents of change."--Publisher description.

This paper will explore connections between the concepts of community development and ecology. Initially the tendency was to think there should be a total melding of the principles and practices of community development with those of an ecological understanding but on reflection this has not and indeed is not necessarily the case. The relative epistemological positioning of two different groups, one strongly associating with social justice and the need for people to be at the centre of our economic, environmental and social understanding; and the other clearly seeing the plant and ecology/environment being paramount. While there are a myriad of connections the focus of much community development has been around human welfare based on principles of social, political and economic justice. This has at times been to the detriment of ecological sustainability. Conversely ecology and particularly aspects of deep ecology have focussed on the 'other than human' aspects of the planet and at times seemed almost 'anti 'human and overlooking the need to work with the social almost entirely. This paper briefly outlines the historical separation of the social from the ecological then goes on to explore alternative understandings that bring together principles of community development and ecology. Three examples are used to highlight the principles and practices that are being used across diverse contexts but all informed by common norms and values that are consistent with both community development and ecology. Concepts such as subsidiarity, participation and empowerment that form the basis of community development praxis are critical to the development of local sustainability. The combination of these aspects is evidenced in the three examples. Each is very clearly located in the local context and is built on sound ecological and community development understandings but each is also well aware that the need for a broader perspective is imperative to achieving global goals.

This report examines the flowering ecology (flowering patterns and the production of floral resources, i.e. nectar and pollen) of important Australian melliferous (honey-producing) flora. Aspects of flowering ecology that can have a negative impact on invertebrates, including honeybees, were also investigated. The research was based on information sourced by highly experienced, commercial beekeepers and, so, provides a valuable written record of long-term observations relating to flowering ecology which otherwise may be lost following the death of beekeepers. Results of this study are of far-reaching importance, not only to the beekeeping industry, but to land managers, the general public and the future of Australian flora and fauna.

An understanding of flowering ecology is vital for many reasons, including implementing appropriate management practices which ensure the sustainability and growth of natural resources and industries like the beekeeping industry. Despite the importance of such studies, very little research has considered flowering ecology in Australian flora. Furthermore, research often was based on short-term data; long-term data are widely acknowledged as being necessary in such research in order to determine ‘real’ flowering patterns. Thus, studies of flowering ecology which use long-term data are vital.

The papers consider such questions as how to build community resilience in the context of profound environmental threat, how to ensure sustainability through community processes and how to assess community progress in responding to threats to the ecosystem.
