Keywords: Bio-economy Forest management Mediterranean Wildfire

Wildfires represent a threat to forests and society and the risk of wildfires is expected to increase with global change. How should wildfires be tackled in the future? A paradigm shift is needed from the current focus on fire suppression to the management of forests, accompanied by the improved understanding that forests are a valuable resource and provide many benefits to society. Through the development of high value-added products, materials, fuels and chemicals, a forest-based bio-economy could provide the necessary investments and incentives to ensure sustainable, integrated forest and fire management strategies and thereby reduce fuel loads and fuel continuity, while at the same time revealing that forests are a valuable resource and provide many benefits to society.

1. Introduction

2. Wildfire prevention through forest management

Wildfires are a natural phenomenon in many forest ecosystems around the globe. Catastrophic wildfires, however, represent a threat to forest resources and society and cause significant economic damage and loss of human lives (Doerr and Santín, 2016; San-Miguel-Ayanz et al., 2013), as seen this summer in central Portugal and southern Spain. The Mediterranean basin is a global wildfire hotspot and wildfires in just five Mediterranean countries (France, Greece, Italy, Portugal and Spain) currently affect approximately 450 thousand ha year− 1, representing 85% of the total burnt area in the whole European Union and an annual economic damage of about 1.5 billion euros (San-MiguelAyanz and Camia, 2010). However, such a figure is an underestimation, as the full value of the numerous ecosystem services provided by forests and affected by wildfires is not taken into account. These five countries have been estimated to invest 2.5 billion euro annually on prevention and mostly suppression (Birot, 2009). Despite a decline in the number and area affected by wildfires in Europe and globally (Andela et al., 2017; Doerr and Santín, 2016), the damage from wildfires - expressed in the volume of wood that is lost - has increased during the 20th century. Moreover, this trend is expected to continue in the next decades due to climate change (Seidl et al., 2014), which requires rethinking how to effectively tackle wildfires in the future (Moritz et al., 2014).

In a context of climatic conditions which favor wildfires, the changing forest resource - in terms of area, growing stock and structure - has been a key factor in the increased frequency and impact of wildfires in the European Mediterranean region (Seidl et al., 2011). Driven to large extent by largely by changing socio-economic conditions (Moreira et al., 2011; Mourão and Martinho, 2014), forest resources in this region have expanded greatly due to active afforestation (especially in Portugal and Spain) and to natural vegetation encroachment after abandonment of agricultural lands (Kuemmerle et al., 2016). Mediterranean forests are generally characterized by low active forest management with wood extraction representing low shares of the increment (Levers et al., 2014). Consequently, the young, expanding and largely unmanaged forests contain high fuel loads and favorable conditions (fuel continuity over large areas) for rapid and large spread of wildfires, which at the same time can result in large CO2 emissions. Basic forest management practices (e.g. tree species selection, thinnings, harvesting systems), as well as other land management practices, can contribute to reducing wildfire risk through the reduction of fuel loads and altering fuel continuity at the landscape level (Birot, 2009; Corona et al., 2015; Fernandes, 2013; Moreira et al., 2011; SanMiguel-Ayanz and Camia, 2010). Such practices should adapt and spatially diversify the structure of the forests to make them less prone to the risk of wildfires (Lauer et al., 2017). This would lead to more resilient forests as they would be better able to withstand the

slowly emerging in the region (Martínez de Arano et al., 2016). The development of new, high value-added products, materials, fuels and chemicals in the Mediterranean region needs to take place in a synergistic relationship with the enhancement of the long-term resilience of forest ecosystems and the provision of ecosystem services. Adequate policy frameworks and policy incentives are crucial to attract necessary investments and support the structural development of specific Mediterranean value chains, infrastructures (e.g., bio-refineries) (cf. Koukios et al., 2017), which will support the development and financing of integrated forest and fire management strategies. The political momentum triggered by the Paris Climate Agreement and the global Sustainable Development Goals offers a unique opportunity to address the problem of wildfires. A forest-based bio-economy will offer opportunities to tackle wildfires through private and public investments. These investments are needed to finance and develop sustainable, integrated forest and fire management activities at relevant scales that can, in turn, ensure the resilience of the Mediterranean forests - and ultimately society - to confront the problem of wildfires.

consequences of global change (Moritz et al., 2014). If carefully planned, forest and fire management could thus be integrated to jointly reduce wildfire risk and to supply (high-quality) timber or biomass, as well as other ecosystem services, in the context of global change. However, active forest management is currently absent in many parts of the region (Valente et al., 2015) due to the lack of forest value chains and markets for both products and the provision of ecosystem services. 3. Existing wildfire policy Despite the existing scientific knowledge that forest management as well as other land management practices - could help to prevent wildfire risk, existing legislation and policy generally focuses on suppressing wildfires (Fernandes, 2013; Montiel-Molina, 2013). Unfortunately, the focus on fire suppression instead of on fire prevention, in a context of already low management intensities, leads to the paradox of an increased accumulation of biomass, thereby paving the way to high intensity fires surpassing the most sophisticated suppression capacities (Collins et al., 2013; Moreira et al., 2011; San-MiguelAyanz and Camia, 2010). Thus, while wildfire suppression may be effective in reducing the burned area in the short term, a suppression strategy may not be advisable in the long-term, especially in a context of global change (Curt and Frejaville, 2017).

4. Paradigm change Human actions are the main cause of wildfires as ignition is mostly due to runaway agricultural fires, negligence and arson (Ganteaume et al., 2013). This clearly indicates a perceived low value of forests. Therefore, to effectively address the problem of wildfires change, a new paradigm is needed that is rooted in the understanding of Mediterranean landscapes as complex, fire-prone, socio-ecological systems (Tedim et al., 2016). In this new paradigm, the current focus is shifted from fire suppression to fire management at the landscape scale (Collins et al., 2013; Corona et al., 2015; Moreira et al., 2011; San-Miguel-Ayanz et al., 2013) and society values the many benefits that forests provide to society. The new paradigm builds around recognizing forests as a valuable resource that provide important renewable biological resources and other ecosystem services. A transition towards a bio-economy, as planned in many countries (e.g., Lainez et al., 2017), could offer opportunities to finance and operationalize long-term, landscape-scale management strategies.

5. Bioeconomy as a solution to tackle wildfires The bio-economy is expected to become a key growth engine in the 21st century and forests are expected to play an important role in the future bio-economy, in the Mediterranean (Koukios et al., 2017; Lainez et al., 2017), as well as Europe as a whole (Pätäri et al. 2016; Scarlat et al., 2015). Studies based on theory (Regos et al., 2016) and practice (Evans and Finkral, 2009) have already linked woody biomass extraction to reduced risk of wildfires systems, but indicate it is still difficult to develop profitable value chains with bio-energy (Evans and Finkral, 2009). However, a bio-economy offers many more opportunities than bio-energy systems only. The development of new technologies provides unprecedented possibilities in transforming biological resources into new bio-based solutions that can replace fossil-based products and non-renewable raw materials. Cellulose and lignin, which are widespread compounds found in plants, are important components from which new bio-based construction materials, textiles, chemicals and plastics can be developed (Sillanpää and Ncibi, 2017). Innovative forest-based business models already exist in the region, including a world-market leader relying on regional resources to produce and sell cork products and flooring worldwide (Hermann, 2009). Furthermore, new business models for not yet commercially explored resources, including medicinal and aromatic plants, honey, mushrooms, etc. are 2
