The role of Marxan in multi-objective Marine Spatial Planning:Building capacity to ADRIATIC+
5 th to 9 th of September, 2016 - Veli Lošinj, Croatia
MSP as a challenge for science-to-policy
Knowledge needed as:
Conceptual and methodological approaches
Knowledge of system functioning at different spatial scales and with time
Data and tools to support decisions
“MSP is a practical way to create and establish a more rational organization of the use of marine space and the interactions between its uses, to balance demands for development with the need to protect marine ecosystems, and to achieve social and economic objectives in an open and planned way.”
Proposals and recommendations for an operational cross-border MSP process
ADRIPLAN methodology
Guideline to be replicated for other MSP case studies in the AIR and Mediterranean area of study, to be adapted at different scale
Main outputs
Methodological framework
Initial Assessment for the AIR
Analysis of coexistence and compatibility among uses, cumulative impacts, socio-economic analysis for the AIR and the two Focus Areas
Strategic Plan for the Adriatic-Ionian Macroregion
Portfolio of Actions for the Focus Areas

Our focus: tools supporting MSP
Moving from data inventory, to integration within the ADRIPLAN methodology, to supporting tool for MSP planning
Use, customization, development, integration in the Portal
Types of MSP tools
Identifying spatial interactions between activities
Risk assessment of cumulative effects of human pressures
Decision support systems
Web-based vs. GIS-based tools
Designed for different users (programmer, scientist, strategic planner, case officer, public),
To address different stages of the plan
Tools4MSP
Collecting and making available MSP data in ADRIPLAN
Tool to be used by partners collaboratively for:
GeoNode plugin (python)
Direct interaction with stored data
The users can build several scenarios (called Case Studies) by choosing the analysis area, the data layers, the analysis grid cell
The output includes: geographical layers, raw data,
base statistics and graphs
The spatial outputs from each run are automatically saved and
published through the portal

Tool4MSP - Cumulative impact
Identify areas in the marine space where the environmental
components are more exposed to anthropogenic pressures
Activities and uses (e.g. Maritime transport)
Environmental components (e.g. Marine mammals)
Pressures (e.g. Underwater noise)
Sensitivities: the sensitivity of each environmental component to each pressure generated by a maritime use
firstly introduced by Halpern et al. (2008) at global
scale, then implemented in several Marine Regions
(Mediterranean by Micheli et al. (2013), Baltic Sea by
(Korpinen et al., 2013), and North Sea (Andersen et al., 2013)).

Marxan implementation to the Adriatic-Ionian Region
when, where and why we use Marxan?
PROPOSED FRAMEWORK for the Adriatic-Ionian region case study
adapted from Mazor et al., 2014. The Crowded Sea: Incorporating Multiple Marine Activities in Conservation Plans Can Significantly Alter Spatial Priorities. PLoS ONE 9, DOI: 10.1371/journal.pone.0104489
STEP 1= description of the study area in different scales and relative main issues (on the basis of Adriplan results, issues, priorities and needs), answering to the need to apply systematic approaches at various scales (Giakoumi et al., 2012)
STEP 2= definition of the aim of the analysis to be realized carrying out different case studies (on conservation protection and on major economic marine activities for the area)
STEP 3= definition of conservation features, costs, targets for each case study
STEP 4= collecting and pre-processing data layers for creating the input datasets
STEP 5= implementation of the spatial prioritization tool: running Marxan for the different case studies on different domains
STEP 6=evaluate trade-offs/development of planning scenarios to discuss with stakeholders
STEP 7= rerun with different targets
STEP 8= final portfolio of planning scenarios ready for discussion with decision-makers. The final plans will meet biodiversity targets; will achieve economic objectives, while minimize costs.
Study area
Domain 1 Adriatic-Ionian Region
Domain 2 Italian side of the AIR
Study area
Domain 3 Marine waters of Emilia Romagna Region
General aim of the analysis
On the basis of the peculiarities of the AIR (EUSAIR pillars), the following priorities, both in terms of environmental protection and socio-economy productivity, have been identified for the areas of study:
Protection of the environment: in line with MSFD (e.g. protecting at least 10% of the seabed is currently exploited by trawling) and Biodiversity Convention (increasing the 10% of marine areas);
Sustainable development of aquaculture (also focusing on the proposal for new offshore areas between 3nm and 12 nm);
Sustainable development of fisheries (both commercial and artisanal);
Sustainable development of tourism: guaranteed by the previous 3 points as well as preserving transport and sand deposits activities (specific activity for the Emilia Romagna region), as important activities of the area.
Specific aim of the analysis
Specific objectives will be achieved by developing specific case studies:
Identifying priority areas to design networks of MPAs for biodiversity conservation;
Identifying priority areas to design aquaculture farms, favouring in particular offshore sites.

Conservation features 3
Costs
Lessons we are learning on the use of Marxan
stakeholders/expert involvement for the finalization of the problem, the observation of specific data/thresholds, and in-depth literature review
consider the time required to observe and elaborate data (pre-processing phase)
importance of a tool for data collection and management (Adriplan Data Portal)
need for a clear definition of the problem and of the goals (it was useful to start from the Adriplan experience, as well as to adopt the workflow of Mazor et al., 2014)
different approach for the biodiversity conservation and aquaculture analyses
