Spatial Representation of future scenarios serves as a valuable input for further analysis such as ecosystem services mapping and valuation. There are four ways to generate a scenario map:
- Collective mapping asks stakeholders to draw future scenarios or components on a map, then combines the results to generate a consensus scenario map.
- Simulations predict the future based on the land/marine use system, which can be described by a variety of models, such as economic, environmental and agent-based models.
- Rule-based allocation allocates changes spatially based on user-defined transition rules. The rules can come from empirical data (trend-based models), expert judgments or stakeholder perceptions.
- Optimization models can select locations and types of intervention to achieve specific goals and related outcomes. The "ideal" land/marine use plan suggested by optimization modeling can also serve as a scenario.
Based on your project goal, data availability, and budget, you can select one or more approaches to create a scenario map.
