• 4th Scenario

For the cardoon and miscanthus the same maps of the 2nd Scenario were considered, with the exception of the "Natural and semi-natural vegetation with conservation value" map and those related to the "COS 2010", "CLC 2012" and "COS 2015" not considered at the intersection as it presents a smaller number of data, limiting the area obtained as suitable for the cultivation of this crops. In the case of paulownia, the same as the two crops occurs but with the di fference that the map of "Natural and semi-natural vegetation with conservation value" was considered.

In Table 3 all the data considered to obtain the adequate areas for the implementation of cardoon, miscanthus and paulownia in mainland Portugal are presented.

In Figure 4 the 4 scenarios created for the cardoon are shown, being visible the evolution and di fference of the area obtained in each case.

The 4 scenarios created for miscanthus are identified in Figure 5, showing the evolution and di fference of the area obtained in each case.

In Figure 6, the 4 scenarios created from paulownia are identified, showing the evolution and di fference of the area obtained in each case.

### 3.1.2. Suitable Areas/Soils for Microalgae Cultivation

• 1st Scenario

Only for the microalgae case the map designated as "Presence of physical obstacles" was considered, with mostly stony areas, which means unsuitable areas for cultures of other species besides microalgae. This map, as well as those relating to "Insolation", "Temperature" and "Land steepness" (obtained from the same source) and those of "Municipalities of mainland Portugal with CO2production in the energy and industrial sector" were considered for all scenarios.

Regarding the "COS 2010" and "CLC 2012", only those areas identified as bare rock were selected. The "COS 2015" was not included because this criterion was not considered on the map.

The protected areas were considered, since it is unknown if it is possible or not to use these zones for the development of microalgae.

• 2nd Scenario

The same maps identified in the 1st Scenario were considered, not including the protected areas, to verify in what extent this factor can affect the appropriate area for the development of microalgae.

• 3rd Scenario

The same maps identified in the 2nd Scenario were considered, without the parameter's integration of the "COS 2010" and "CLC 2012".

• 4th Scenario

The same maps identified in the 3rd Scenario were considered, without including the protected areas, to verify how the suggested area for the development of microalgae could be affected.

All considered maps and data to obtain the appropriate areas for the implementation of microalgae in mainland Portugal are shown in Table 4.

The 4 created scenarios for the microalgae culture are identified in Figure 7, showing the similarity of the area obtained in all cases.
