**General Objectives (GOs)** & **General Lines of Action (GLAs)** & **Actions/Measures/Narrative** \\ \hline \hline GO2. Defragmenting landscape and protecting biodiversity & Green roads; green roofs; cycle paths; riparian vegetation; buffer strips; forest belts; hedges; green bridges as corridors for wildlife; conservative farming practices; conservation of autochthonous vegetation. Note that the effectiveness of green roofs as stepping stones depends on context and target species. \\ \hline GLAS. Improving the quality of the urban, peri-urban, and rural landscape & Enhancement of historic green zones; urban green areas for recreational services; design of new green areas; gardens; green roofs, re-naturalized areas. \\ \hline GLA6. Preservation of agricultural systems & Conversion of arable land to permanent lawns; implementation of conservative agricultural practices; hedges; rows of trees; fair management of forest systems; promotion of remediation actions in forestry areas; conservation of natural elements; buffer strips; grassy slopes. \\ \hline GLA7. Reduction of greenhouse emissions & Implementation of multifunctional wooded areas; planting of forest belts; fast-growing forestry areas; promotion of fire prevention policies and management. \\ \hline GO3. Implementing measures to address climate change & GLA8. Increase of carbon sequestration & Forestry maintenance; choice of vegetable species (according to longevity, management, fast-growing nature, and other issues); protection of soil. \\ \hline GLA9. Implementation of adaptation measures against hydrogeological risk & Green roofs, green roads, and grassy strips (to ease the drainage of rainwater); slopes protected with vegetation; conservation of riparian species in waterways; implementation of infiltration basins; enhancement of wetlands; reforestation. \\ \hline GLA10. Strengthening of governance processes concerning environmental components & Involvement of municipal administrations, according to a participative planning approach. The GIs planning processes must be trans-and-multidisciplinary, and include several types of actors (professionals, citizens, local authorities, and other stakeholders). \\ \hline GLA11. Improving the sharing and dissemination of information & The stakeholders should be involved through meetings, online surveys, thematic meeting, etc. \\ \hline GO4. Improving the governance & SEA procedure can ease the inclusion of GIs in plans and programs. Such an approach has potential to promote the consideration of environmental issues and definition of adaptation to climate change measures. The GIs should be explicitly addressed in the plan or program. The planning of green urban areas should include approaches based on ecological networks or networks of GIs. \\ \hline \hline \end{tabular}

Table 7: _Cont._and successful implementation. In the design process of a GI network, consideration of various planning tools is needed. The practical tools include such provisions as interventions of habitat creation, protection, valorization, and re-naturalization. A proper planning and design of a GI network needs to refer to policies, strategies and plans defined at European, national, and regional scales. As a reference framework able to support and steer the decisional process, planners and decision-makers should consider: Directive 92/43/EEC 'Habitats Directive', Directive 2009/147/CE, national laws, regional norms, and provisions of plans and programs adopted at different hierarchical levels (from national to local scales).
