- Background: The dynamics of phosphorus (P) in the environment is important for regulating nutrient cycles in natural and managed ecosystems and an integral part in assessing biological resilience against environmental change. Organic P (P-o) compounds play key roles in biological and ecosystems function in the terrestrial environment being critical to cell function, growth and reproduction.Scope: We asked a group of experts to consider the global issues associated with P-o in the terrestrial environment, methodological strengths and weaknesses, benefits to be gained from understanding the P-o cycle, and to set priorities for P-o research.Conclusions: We identified seven key opportunities for P-o research including: the need for integrated, quality controlled and functionally based methodologies; assessment of stoichiometry with other elements in organic matter; understanding the dynamics of P-o in natural and managed systems; the role of microorganisms in controlling P-o cycles; the implications of nanoparticles in the environment and the need for better modelling and communication of the research. Each priority is discussed and a statement of intent for the P-o research community is made that highlights there are key contributions to be made toward understanding biogeochemical cycles, dynamics and function of natural ecosystems and the management of agricultural systems.

- Healthy urban ecosystems are increasingly recognised as important for resilient cities and need to be considered as part of GPR. Urban nature-based solutions (NBS) comprising green (vegetation) and blue (water) infrastructure need to be considered at multiple scales from the bioregions, through to catchments, neighbourhoods/precincts, blocks, streets, and buildings, including linkages through and in GPR areas. This chapter describes how climate change—particularly extreme urban heat—is expected to affect Australian cities, and how green and blue infrastructure can help GPR to be incorporated into urban adaptation and mitigation solutions. Topics covered include water-sensitive urban design, nature-based solutions, and urban cooling. The chapter outlines how nature-based solutions can be incorporated into higher-density regenerative urban redevelopment through new technologies and supported by planning models, many of which can be best designed and managed at precinct scale. The ‘additionality’ of green and blue nature-based solutions can offer residents of GPR areas increased liveability and enhanced resilience in both normal and extreme weather.

Integrating Transition Processes for Regenerating the Greyfields

Bokkapitel (refereegranskat)abstract
- This book has introduced two new (linked) models for greyfield precinct regeneration—place-activated and transit-activated GPR—with a new set of processes to enable them. The need for new design, planning, and engagement tools that must be integrated into all urban development is also seen as key to unlocking greyfield regeneration. Designs for such precincts have proliferated, but planning systems are still hindering their implementation, especially those systems related to land-assembly issues in the established, occupied middle greyfield suburbs. Planning must change, and a potential way ahead involves the planning processes demonstrated in this book. A first step involves district greenlining, which enables identification of strategic planning challenges and priorities for action at a district scale along a transit corridor (transit-activated GPR) or in precinct-scale areas in typical middle suburbs with high redevelopment potential (place-activated GPR). Their key attributes are gleaned from the previous chapters and summarised in this chapter. A final plea is made here for partnerships to be created from the engagement of all stakeholders: government, community and civil society, innovators, and developers. Greyfield Precinct Redevelopment Authorities established within state governments as part of a federal Better Cities 2.0 program could guide this transition.

Planning, Design, Assessment, and Engagement Processes for Greyfield Precinct Regeneration
- 2021
-

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter expands on the required set of innovations in urban planning, precinct design, performance assessment, and engagement processes outlined in Chap. 1 that are core to the delivery of greyfield precinct regeneration (GPR). The sections that follow dive deeper into the key transitioning processes and provide case-study illustrations for place-activated GPR drawn from the City of Maroondah’s Greening the Greyfields project.

The Global Greyfields Transition : Why Urban Redevelopment in Low-Density, Car-Based Middle Suburbs Needs a New Model
- 2021

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter provides the framework and rationale for Greening the Greyfields and its two new models for greyfield precinct regeneration (GPR): place-activated and transit-activated GPR. They provide a basis for regenerative urban redevelopment in the middle-ring greyfield suburbs of fast-growing, low-density cities. Place-activated GPR advances a new development model for the ‘missing middle’ in cities: new medium-density housing at precinct scale. Transit-activated GPR extends new sustainable modes of mobility into car-dependent suburbs. Both processes are required for retrofitting suburbia to fix the shortcomings of mid- to late-twentieth-century urban planning and development.
