Abstract
This paper demonstrates the ability of visualization and simulation techniques to aid, and simulate current and future directions in coastal planning. Two communities examined are the coastal city of Hobsons Bay on Port Phillip Bay within the Melbourne metropolitan region and the coastal rural town of Apollo Bay, in Australia, are interrogated through a progression of projections and simulated forecasts from 2014 to 2050. The purpose is to comprehend their growth risks as it relates to their coastal edges and land use planning mechanisms in addressing these changes. The analysis uses Geographic Information Systems (GIS) associated with planning application software, and the paper offers recommendations in progressing this inquiry.
Highlights
Coastal cities around the world over the past few decades have grown at an incredible rate.Integral with this growth have come major challenges relating to land use planning, social relationships, economic development, bio-diversity and the degradation of the ecological footprint
The research undertaken for this paper relating to the Apollo Bay has generated six discussion points which are listed below that can be summarized as: Population increases generating more emissions and greater impacts of climate change; Increased consumption of energy and water resources; Open space allowances decrease for new developments and General overall open space decreases per head of population; Urban density increases; New residential and or commercial development will add greater stress on existing physical and or natural infrastructure and, More mixed commercial / residential developments in the metropolitan and regional centers
The research undertaken for this paper relating to the Hobsons Bay has generated eight discussion points which are listed below that can be summarized as: Population increases generating more emissions and greater impacts of climate change; Increased consumption of energy and water resources; Open space allowances decrease for new developments and General overall open space decreases per head of population; Urban density increases; For metropolitan areas (i.e. Hobsons Bay the scale of development) will increase; New residential and or commercial development will add greater stress on existing physical and or natural infrastructure; The exodus of more jobs
Summary
Coastal cities around the world over the past few decades have grown at an incredible rate. These forces include: population growth (i.e. the type and quantity of human demand for land); the existing and future properties of the land (i.e. current land status or changes due to nature and human activities); and, technical changes of a land use planning system (i.e. zoning or the influence of other external factors) As this development growth continues one question that arises is ‘is this continued growth or development sustainable?’ Ciegis (2009) described the problems of trying to identify the essential features of sustainable development that offer models of management of ‘sustainable development’. Demographic and planning scenarios Community Vizsoftware performs four functions including: the estimation, amount and location of new development allowed in an area according to current or proposed zoning regulations; the suitability of the new development to an area; the allocation of where growth is most likely to occur over a specific time span and the development of a series of environmental indicators showing the impact of the new development on the landscape. Through the impact function in Community Viz, 15 indicators were developed showing the impact of development over time on the urban landscape (fig. 1)
