‘Greening’ Green Infrastructure. Good Italian Practices for Enhancing Green Infrastructure through the Common Agricultural Policy
Abstract
:1. Introduction
2. General Overview
2.1. Enhancing Conditionality within the Common Agricultural Policy
2.2. From Ecological Networks to Green Infrastructure: An Attempt to Integrate Agriculture and the Environment
3. Materials and Methods
- -
- legislative references displaying an overlapping of competences and administrative sectors;
- -
- spatial constraints due to poor directions for green infrastructure implementation and weak support for accommodating agri-environmental measures within spatial planning;
- -
- structural constraints such as land-use and land-tenure fragmentation, lack of cooperation between public and private stakeholders.
- -
- They are good practices where existing programming tools have been linked to CAP funding for the implementation and management of GI;
- -
- They target contexts differing in terms of environmental, productive, social and regulatory features;
- -
- They are part of regional programming and planning (such as the Environmental Regeneration Program, Provincial Territorial Plan, Regional Landscape Plan) with a specific focus on biodiversity conservation;
- -
- They involve the agricultural sector stakeholders in the policy process development for the definition of objectives, strategies and interventions.
- -
- Study Case 1:
- -
- Consultation of 7 territorial plans and programs (Hydrological Structure Plan; Po River Basin Management Plan; Piedmont Regional Territorial Plan; Piedmont Rural Development Programme; Regional Water Protection Plan; Provincial Coordination Plan; Regional Guidelines for River/Lake Contracts) and the management plans of 2 protected areas; 1 Memorandum of Understanding for the signing of the Wetland Contract; 5 progress reports (stakeholder analysis; scientific description of the area; Wetland Contract trend and oriented scenarios; participatory process development; Wetland Contract and Action Plan);
- -
- Open ended and focused interviews to 1 manager of the Vercelli Province, and 1 manager of the Piedmont Region in charge for River/Lake/Wetland Contract coordination;
- -
- Direct and participant observation to 5 Technical Secretariat meetings and 3 Focus groups [44].
- -
- Study Case 2:
- -
- Consultation of 5 plans and programs (Regional Water Protection Plan, Lazio Rural Development Programme, Provincial Coordination Plan, Provincial Ecological Network, Environmental Restoration Program of Agro Pontino); 1 Memorandum of Understanding for the subscription of the Pact for Biodiversity;
- -
- Open ended and focused interviews to 1 manager of the Latina Province, 1 manager of the Lazio Region in charge for agri-environmental measures coordination, and 1 director of Confagricoltura association;
- -
- Direct and participant observation to 4 Technical Secretariat meetings [44].
- -
- Study Case 3:
- -
- Consultation of 2 plans and programs (Management Plan of the Torricchio Mountain Nature Reserve, Marche Rural Development Programme); 2 scientific papers on the topic; 1 Agri-Environmental Agreement, and 1 Land Stewardship Agreement;
- -
- 1 focused interview to the delegate of the director for agri-environmental policies in the Torricchio Mountain Nature Reserve.

Programming Period | Reform | Main Contents Related to Environmental Issues |
---|---|---|
2000–2004 | Agenda 2000 | CAP reforms broke the link between direct payments and production. More emphasis was placed on the environment and animal welfare.
|
2005–20092010–2013 | Fischler Reform Health Check | Rural development plays an increasing role in setting CAP strategies, aligning with the EU’s structural policy. |
2014–2020 | Europa 2020 | The CAP budget is split into two headings (Pillar I and Pillar II) Pillar I Under the direct payment scheme, the greening payment is introduced as the second most important component after the basic payment, for an amount corresponding to 30% of the national ceiling, equal for all Member States. It is paid annually per eligible hectare. Farmers should comply with the following agricultural practices beneficial for the climate and the environment:
This accounts for 28% of the CAP budget, allowing for spatial allocation of expenditure within Rural Development Programmes (RDPs). The measures common to all regional programs are:
|
Measures | Sub-Measures |
---|---|
Measure 4—Investment in physical assets | 4.3 Aid for investment in infrastructures tied to developing, modernizing, and adapting agriculture and forestry 4.4 Aid for non-productive investment in meeting agricultural, environmental, and climate targets |
Measure 7—Basic services and village renewal in rural areas | 7.3 Aid for creating, improving, and expanding basic local services for the rural population, including recreational and cultural activities, and related infrastructure 7.4 Aid for investment in recreational infrastructure for public use, tourist information, and small-scale tourist infrastructure 7.5 Aid for studies/investments tied to maintaining, reclaiming and restoring the natural and cultural heritage of villages, rural landscapes, and areas with a high natural value, including their social and economic aspects, as well as ecological awareness-raising initiatives |
Measure 10—Agri-environment and climate | 10.1 Aid for agri-environmental and climate commitments 10.2 Aid for the conservation, sustainable use, and development of genetic resources in agriculture |
Measure 12—Payments under Natura 2000 and the Water Framework Directive | 12.1 Compensation payments for agricultural areas in the Natura 2000 Network 12.2 Compensation payments for forestry areas in the Natura 2000 Network 12.3 Compensation payments for agricultural areas included in basin hydrological plans |
Measure 15—Forestry, environmental and climate services and forest conservation | 15.1 Payments for forestry, environmental, and climate commitments |
Measure 16—Cooperation | 16.2 Aid for pilot projects and developing new products, practices. processes, and technologies 16.5 Aid for joint actions performed to mitigate climate change and adapt to it, and for joint approaches to environmental projects and existing environmental practices |
Component | Description | |
---|---|---|
Core natural areas | Areas of high-quality habitats that are managed primarily for biodiversity conservation, whether or not they are protected. | |
Buffer zones | Transitional areas, located around highly natural areas where restrictions on resource use and special development measures are undertaken in order to enhance the conservation value of the protected area. | |
Ecological corridors | Linear and continuous structures in the landscape varying in shape and size, connecting highly natural areas to each other and representing the key element of ecological networks since they allow for species mobility and genetic exchange, an indispensable phenomenon for maintaining biodiversity.These corridors form the “edges” in the network, linking core nature areas and stepping stones. | |
Stepping stones | Smaller areas of quality habitats that are intended to help the movement of individuals by serving as islands of favorable habitats between larger core nature areas. These also represent “nodes” in the ecological network that, due to their strategic position or composition, may support species passing through a territory or host particular microenvironments in critical habitat situations. |
Subject of Reforms | Intergovernmental Relationships | Internal Local Government |
---|---|---|
1. Organizations | 1.1 Structural (i.e., change in number of Local Authorities, administrative boundaries) | 1.2 Organizational (i.e., changes in relations between political and administrative bodies) |
2. Decision-making | 2.1 Functional and procedural (i.e changes in the Administrations’ functions, procedures) | 2.2 Local programming (i.e, implementation/update of programming tools, plans) |
3. Financial resources | 3.1 Funding (i.e., change in EU, national, regional funding) | 3.2 Local funding (i.e., variation in fares regimes, local accounting regulations) |
Target Area/Region | Promoter/Coordinator | Productive Features | Policy Process | Target Area Extension | CAP Payments |
---|---|---|---|---|---|
Vercelli lowlands plain, Piedmont | Province of Vercelli | Submerged rise cultivation | Wetland contract | 70,736 hectares | Pillar II |
