A community of practice for the sustainable management of forests surrounding the Occhito Lake in Puglia, Italy

Giovanni Santopuoli

Through an innovative and collaborative form of governance and an environmental and forestry management plan that includes nature-based solutions, the forested area surrounding the Occhito Lake will become more resilient to climate change. The new approach preserves ecosystem services of forests and valorise rural areas.

The lake of Occhito marks the border between Molise and Puglia regions for about 12 km in the South-eastern part of Italy. The lake was created along the Fortore river through a dam and built as water reservoir for multiple water uses at the end of 1950s. It is the largest artificial lake of Italy, with a capacity of about 250 million m3. In the 1970s, a large intervention of conifer reforestation was carried out in the area surrounding the lake with the aim of enhancing the hydrogeological protection of the area. Although the lake is man-made, it has has an exceptional ecological value and the area is protected under the EU Natura 2000 network (IT9110002 and IT7222248 sites).

The area suffers from agricultural land abandonment. Forest management and planning is lacking, with scattered silviculture interventions based on local needs. Moreover, forest is damaged by forest fires, that are aggravated by climate change, due to increasing summer temperature and drought events.

The PABLO project (Environmental and forest planning of Occhito Lake), aims to bring public and private business partners together to form a community of practice that works towards managing the forested area sustainably, with a combined approach that considers environmental, economic and social aspects. The project focuses on the eastern side of the lake, included in Puglia region. However, it has high potential to be an inspiration source for administrations of Molise region (western side of the lake) that are facing similar challenges. LiDAR drones together with traditional monitoring techniques were used to identify the main vulnerability elements of the area and to draft an environmental and forestry management plan. A voluntary “Forest Agreement” has been proposed as a new collaborative governance scheme to support the actual implementation of the plan. Finally, the prescribed burn technique (widely reported and discussed in literature, also as prescribed fire, controlled fire/burn) was tested in a pilot area. Its full-scale applicability to reduce fire risk in the region has been discussed and brought to the attention of local and regional administrations to fill in the existing legislation gap.

The new management system of the forested area is expected to provide many environmental, economic and social benefits. Cooperation among project partners, municipalities and associations, private landowners and local enterprises is key for delivering expected results.

Case Study Description

Challenges

Forest fires are currently one of the main causes of damage to forests in the area surrounding the Occhito lake. The increase in air temperature, the reduction in average annual precipitation and the greater frequency of extreme weather events (heat waves) are climate change drivers  that favour the spread of fires, with particular reference to forest fires. Model projections (National Climate Change Adaptation Plan, 2023) suggest that Southern Italy will face higher temperature and reduced precipitation: considering the worst scenario (RCP 8.5) temperature might increase up to 2°C and precipitation might decrease up to 20% by 2050. An increase in the number of hot and dry days and in the number of extreme drought events (duration > 3 months) is also expected.

The situation in Southern Italy is further aggravated by the presence of some forest vegetation types, , that have a high degree of flammability, such as for example the Mediterranean scrub, Mediterranean pine forests, holm oak forests and downy oak forests. In 2020, the Regional Environment Agency (ARPA Puglia, 2022), recorded 398 fires in Puglia, with a total area covered by fire of almost 3,600 ha. Over 40 percent of this area (1,474 ha) was forested. The most affected province in Puglia region is Foggia (where the Occhito forest is located), both in terms of the number of fires and the area covered, with almost 1,200 ha. Since 2013, the average annual surface of individual fire events has always been less than 10 ha (with the exception of 2017), suggesting that prevention and active forest fire management becomes to be effective in the region.

Besides climate change, the agricultural land abandonment leads to more challenges, the accumulation of unmanaged vegetation on the soil and the establishment of new urban settlements in the countryside. Both processes are increasing fire risk for people and assets located at the urban-forest interface, with increasing costs for civil protection, especially in summer.

The poor state of forested area (disruptions, landslides, fires) reduces its effectiveness for slope consolidation and for preserving the ecological state of the lake. Silviculture is practiced through scattered interventions based on local needs and without a management objective. The territory is a mosaic of state, municipal and private properties. Local administrations complain about the lack of a forest management plan and advocate for forestry interventions to maintain forest in a healthy state.  

Policy context of the adaptation measure

Case mainly developed and implemented because of other policy objectives, but with significant consideration of climate change adaptation aspects.

Objectives of the adaptation measure

The PABLO project (Environmental and forest planning of Occhito Lake) aims to promote an innovation and participated process in the forestry sector by bringing  scientific, technical, political and private business partners (community of practice) together. Through a combined approach that both considers the environmental aspects and economic production, the project aims to improve forest resilience and the protective and environmental functions of forest stands of the surrounding landscape of the Occhito lake The project is expected to preserve forest from natural disturbances and multiple challenges, including increasing drought and fire risk due to climate change. Specific objectives are :

  • Promote synergies between private and public entities to favour the sustainable management of forests
  • Introduce innovative and replicable forestry techniques
  • Implement silvicultural interventions of fire prevention and management
  • Train operators for fire prevention also beyond the project life.
Solutions

Within the PABLO Project, three types of solutions are being implemented: (i) preparation of forest management plan for the area surrounding the Occhito lake; (ii) development of a public-private partnership for implementing the management plan; (ii) implementation of a pilot project for applying the technique of prescribed burn to prevent uncontrolled wildfire.

 To ensure long-term sustainability of forest management, a forestry management plan was developed, focusing on the forest landscape surrounding to the Occhito Lake. The management plan includes the objectives, strategies and silvicultural and non-silvicultural interventions to be implemented in the next 10 years to enhance forest fire prevention and to mitigate the hydrogeological instability of the forested area, exacerbated by climate change.

The preparation of the plan was preceded by a detailed forest inventory phase to better characterize forest structure and assess health, vitality and the current management trend. The inventory was prepared by integrating traditional monitoring techniques with remote sensing techniques, in particular, Airborne Lidar Sensor. Field data, using the one-per-stratum stratified sampling scheme, were collected within a total of 85 homogenous areas (according to morphology and forest type), further subdivided in square cells (23mx23m). Among others tree density, species composition, biomass, diameter at the breast hight, carbon stored in the trees were measured in one random cell per each homogenous area.

Qualitative data were also collected to gather information about at the environmental conditions (e.g., slope, aspect, altitude, hydrogeological instability, damage to vegetation), and the governance setting in each area. Several LiDAR drone flights were carried out over the forested area which were used to provide a DTM (digital terrain model), a DSM (digital surface model) and a CHM (digital canopy height model). All data were used to identify vulnerable areas to climate change and other impacts and to inform the planning task.

To facilitate the implementation of the plan, a public-private forest management model was proposed: a voluntary “Forest Agreement” to which various entities operating and managing the area can sign up. They include for example municipalities, environmental associations, local action groups and cooperative enterprises or private citizens that own or manage some land parcels .  Several stakeholders expressed interest, both from Puglia and from Molise region, as well as from PEFC Italy (forest certification management body). The strategic objectives of the Agreement are to increase the territorial governance capability to sustainably   manage the territory and to promote the development of sustainable  supply chains. This will be done through the conservation and provision of ecosystem services, respecting biodiversity, local economy, local culture and landscapes. In the draft Forest Agreement, strategic objectives are translated into 13 concrete actions. They include projects to preserve and enhance the resilience of the forest ecosystems through nature-based solutions aimed at consolidating slopes and at preventing fire risks and pest outbreaks that are worsening due to climate change.

Finally, the applicability of prescribed burn to prevent fire risks was tested in a pilot prioject in an area of 4.84 ha. Prescribed burn is the conscious and expert application of fire on planned surfaces, through applying precise prescriptions and operational procedures. The use of fire is a nature-based solution that makes it more difficult for forest fires to spread through the canopy and reduces fuel availability. Through prescribed burn, fine and dead plant material, particularly susceptible to ignition, is removed or reduced, the vertical continuity of the fuel is interrupted and small open spaces located inside and at the edges of the forest are maintained or restored. It is also a silvicultural technique, as it can favour the selection of most desirable species and change the structure of tree populations, favoring the diametric growth and ensuring greater stability of the forest ecosystem. After identifying suitable areas and training the operators, the pilot project was implemented. Moreover, local administrations started a shared pathway to explore possibilities to fill in the current regional legislation gap (see also the sections “Policy and legal framework” and “Success and limiting factors”), since the prescribed burn technique is not still regulated by specific regional operational guidelines.

The partnership of Forest Agreement partnership will periodically monitor the interventions scheduled within the Forest Management Plan, and more generally the activities envisaged by the Forest Agreement, in terms of effectiveness: the task of coordinating this activity falls into the Managing Body of the Forest Agreement.

Additional Details

Stakeholder participation

Stakeholder participation is at the foundation of PABLO Project that makes the concept of “community of practice” its essential pillar. Communities of practices are groups of people who share common concerns, interests and goals. The PABLO community of practice is composed of public and private entities, that participate in the project with different roles and responsibilities. It includes the Capitanata Consortium (who manages the hydraulic network and reforestation interventions), the ARIA research center of Molise University, three small private agro-forestry enterprises (ATS Montemaggiore, Tecno Forest, D.R.E.Am. Italia), and the regional entity for promoting regional level cooperation (Lega Coop Puglia). Moreover ,t the Agriplan Innovation broker supports the project. Many other entities other entities, like municipalities and private owners with economic interests on the forested area are involved . Several events were organised to inform and share project results and to collect potential interested people to sign the Forest Agreement. With the community of practice approach and the Forest Agreement, people living and working in the Occhito lake territory should become the leading actors for the transition to the environmental, societal and economic sustainability of forest management.

Success and limiting factors

One of the main success factors of the project is the cooperation among different private and public entities to work with a common objective. Several municiplalities became interested in the project and participated in the project events. Together they identified opportunities to contrast land abandonment and depopulation as well as to valorise the territory, opening the opportunity for new and diversified economic activities, like eco-tourism.

Since the project received funding from the Puglia regional development programme, the project activities focussed on the Puglia side of the lake (eastern side). However, the forested area surrounding the Occhito lake also extends over the Molise region (western side of the lake). It faces problems that are very similar to those experienced in Puglia. Thus, the PABLO project made efforts to export its results to Molise. Several exchange activities, such as various meetings were organised where stakeholders from both Puglia and Molise could  participate Some municipalities located in Molise region will take further part in the Forest Agreement, so that they will contribute to and benefit from the activities envisaged by the forestry plan.

Through a bottom-up approach for vertical scaling, from subregional to regional level, the project has the potential of reaching higher levels of governance creating the conditions for similar projects in other areas and increasing knowledge transfer.

The technique of prescribed burn that was tested in the PABLO project lacks proper regulation in Puglia region, although it is envisaged by the regional legislation, has been tested and is receiving increasing attention. Therefore, its operational and full-scale application is  currently limited by a current regional legislation gap. Bringing the attention of various administrations on this issue was a first step to address this gap.   

A long preparatory work was needed to prepare the forest management plan where all information about land use constrains was collected together with data coming from previous botanical, forestry, agronomic and faunal studies. The collection and analysis of LiDAR data also required several resources and was hindered by prolonged adverse meteorological conditions between January and June 2021. Moreover, the Covid-19 pandemics, that prompted the national and regional government to establish several restrictions to field and social activities, further delayed the planned work.

Costs and benefits

The total cost of the project is 498.550,00 Euro, coming from Puglia PSR. The project includes 4 work packages (i. project management and coordination, ii. Monitoring, iii. Implementation, iv. Dissemination). The total costs are split as follow: WP1 (192500 €) 4% of the total, WP2 (10000 €) 2% of the total, WP3 (373000 €) 75% of the total and WP4 (96300 €) 19% of the total costs.

Several benefits are expected from the implementation of the project. Whenever well managed, forests represent an important source of income by provisioning several ecosystem services that can  generate economic, ecologic and societal benefits. A coordinated management of forests is expected to: (i) enhance the protective function of the forest (slope consolidation and water preservation); (ii) increasing growing forest stock; (iii) promoting biodiversity conservation while maintaining wood and non-wood production; (iii) improve forest resilience; (iv) support natural regeneration an natural processes to rewilding the forest; and ; (iv) reduce the number and the severity of fire events and plant diseases originated by pests.

The project is also expected to generate social benefits, by overcoming general scepticism about the possibility to reconcile environmental protection with economic and social aspects. The project seeks to maximise the use of short supply chains for wood products, connecting local suppliers with local consumers. This includes wood products from routine operations, such as the marketing of wood residues, with positive impact on local economies and rural development. This will also contribute to the valorisation of abandoned or marginal rural areas counteracting the rural abandonment and depopulation. Using the forest for recreational activities and eco-tourism through interventions to improve the agricultural-forestry pastoral roads and paths of the area is also promoted.

Implementation time

The PABLO project started in August 2020 and ended in August 2024. The field phase, including forest survey using LiDAR drones, was completed in autumn 2021. The prescribed burn activities were done in spring 2021. The environmental and forest management plan was completed in 2023, and it is pending for final release and implementation. The Forest Agreement is currently open for subscriptions.

Lifetime

The environmental and forest management plan for the area surrounding the Occhito Lake is designed to last for 10 years. A first revision of the plan is foreseen after five years. The first Forest Agreement, once it will be finalised, will be in place for 5 years. All actions envisaged by these management tools will have an indefinite life-time and will be effective in the long-term.
