PILOT MARINE SPATIAL ASSESSMENT TOOL 4 1 Introduction and Background PILOT MARINE SPATIAL ASSESSMENT TOOL 5 1.1. Need 1.2. Objectives Tasmanian coastal waters are highly valued, offering significant The main aim of this project was to develop and trial a spatial It is hoped that the decision support tool will offer valuable social, economic and environmental benefits to society. The assessment decision support tool that allows for identification of insight for decision makers and stakeholders in the early stages way in which the coast is valued and used is dynamic, changing potential competing resource uses which may pose challenges of marine development planning processes by highlighting over time and space. It is realised that there is a need to balance under different development scenarios within the marine any competing use and resource challenges associated with the values of different marine users to ensure social, economic environment in support of the objectives of the RMPS. potential future developments. In this context the tool will be and environmental sustainability for future generations and to The decision support tool will help to: a starting point to help guide decision makers and proponents meet the objectives of the Tasmanian Resource Management on where to focus the more detailed and rigorous aspects • identify the types of uses and values present within and Planning System (RMPS), as enshrined in Tasmania’s resource of planning processes (i.e. more detailed data collection, the marine environment based on existing knowledge management legislation (for example, the Living Marine environmental impact studies and community engagement) and understanding; Resources Management Act (1995) and the Marine Farming needed to inform good decisions. It is hoped that the tool Planning Act (1995)). This project was initiated to address this • provide a starting point for identifying areas which may be will help to initiate and support ‘good neighbour’ practices by need with the specific purpose of developing and trialling most appropriate for given marine uses based on marine use identifying some of the wide variety of coastal and marine users, a spatial assessment decision support tool to assist in the suitability and the least number of conflicts with other uses. encouraging fair consideration of those uses, and therefore assessment of future planning for fisheries and aquaculture and maximise the benefits and minimise the risks associated with • identify relevant information gaps to assist in the related industries within the marine environment. potential developments. development of marine spatial assessment tools To do this a wide variety of spatial data needed to be identified and processes. The project was not designed as a participatory planning and incorporated within a platform that enabled improved As such the tool offers the potential to address specific process or to generate a spatial plan per se. It has considered understanding of the values which exist and their distribution considerations relating to planning developments. a range of scenarios and it is anticipated that project outputs throughout the region.
