When undertaking a planning or zoning task, rarely does a planner have access to all the information or knowledge that they would like for the entire planning area. Whether it might be more consistent ecological data across the entire planning area or a more complete understanding of the full range of social and economic information, a planner is often faced with the following choices:
- Waiting until they have more data (with the ultimate aim of accumulating ‘perfect’ information across all the required datasets); or
- Working with the best available scientific knowledge and accepting that while it is not perfect, it is adequate provided the deficiencies of the data are understood (by the planners and the decision-makers) and clearly explained to the public and to the decision-makers. Insufficient knowledge about marine ecosystems can impede the setting of meaningful objectives or desirable outcomes when planning. David Suzuki in 2002 questioned how can we effectively plan and manage when “… to date all we have actually identified are ... about 10–20% of all living things”, and “… we have such a poor inventory of the constituents and a virtually useless blueprint of how all the components interact?’’
A good understanding of the wider context within which the MPA is situated is an important factor when planning. Due to the levels of ‘connectivity’ in the marine environment and the biological interdependency upon neighbouring communities, an MPA can only be as ‘healthy’ as the surrounding waters. Even a well-planned MPA will be difficult to manage if the surrounding waters are over-utilised, polluted or are themselves inadequately managed.
- The reality is if you wait until you have ‘perfect’ information for planning, you will never start.
- Recognise that marine areas are dynamic and are always changing; and with technological advances, the levels and patterns of use are constantly changing, as are the social, economic and political contexts, so having perfect data is realistically an impossible aim.
- In virtually all planning situations, it is better to proceed with the best available information than to wait for ‘perfect’ data. However, if new data becomes available during the planning process, then incorporate it rather than ignore it.
- Those who are frequently on the water (like fishers and tourist operators) often know as much (if not more) about the local environment than the researchers – so draw upon their knowledge and use it to augment the best available scientific data.
- When resources are limited, seeking new data should focus on providing information that will be useful for ongoing management.
