2.1. Development of bioeconomy in EU countries
The renewed bioeconomy strategy in all EU was launched in 2018. The adoption of this strategy is different in each EU country. With growing knowledge and awareness of the finite nature of fossil resources, and the growing climate, environmental, socio-economic and geopolitical impacts of their exploitation and use, along with their associated risks, the EU and many individual European and other countries have or are currently developing bioeconomy strategies. Until 2020 less than half of all EU countries (Spain, France, Germany, Italy, Latvia, United Kingdom, Austria, Finland, Ireland, the Netherland) have adopted a bioeconomy strategy at the national level. In the residual EU countries, this strategy is under development, or countries have developed other bioeconomy related initiatives.
The EU Bioeconomy Strategy emphasizes that the major opportunity and challenge is sustainable bioeconomy that requires various ecosystem and technological solutions, strategic policies, investments and policies that reward stakeholder innovation, including social entrepreneurship. The European Commission (2019) actively supported and promoted all types of innovations and practices for forestry and bio-based production, sustainable food and farming systems, through a systemic and cross-cutting approach linking actors, territories and value chains. The recent unprecedented COVID-19 crisis has brought to the surface a much wider role that the bioeconomy can have in diversifying supplies for food, feed, and raw materials, contributing to circularity and climate neutrality, whilst at the same time, creating employment and fostering rural development. New perspectives are needed to foster resilience and smooth the transition to a circular post-COVID-19 economy within the framework of the European Green Deal and the European Recovery Plan, in line with the EU Bioeconomy Strategy objectives. This implies embracing a transformative logic focused on turning the current challenges for local economic resilience into opportunities for diversification through deploying the bioeconomy widely.
Therefore, the successful implementation of sustainable bioeconomy strategy concerns all EU countries. Authors analyzing how countries implement bioeconomy strategy and the potential of bioeconomy development instead one country encompassed all EU countries. A large number of authors explored socioeconomic indicators, such as: output and employment multipliers of the bioeconomy sector, competitiveness effects and the differences among EU countries (Ronzon and M’Barek, 2018; Philippidis and Sanjuán-López, 2019; Fuenter-Saguar, 2017; Asada and Stern, 2018). Other authors (see: Hamelin et al., 2019; Withcchel et al., 2019; Mola-Yudego et al., 2019) encompassing all EU countries analyzed the residual biomass potential or potential of agricultural residues and wood biomass potentials for energy. Schipfer et al (2017) revealed the biomaterials scenarios for EU-28 countries up to 2050 and respective biomass demand. Scarlat et al (2018a.b) and Banja et al (2019) analyzed the biogas development and potential form manure in separate EU countries. Banja et al (2019) explored the biomass, Bórawski et al (2019) - biofuels supply for the energy sector in separate EU countries. Liobikiene at al. (2020) showed that the level of land footprint, biocapacity and possibilities of bioeconomy development vary across the EU countries. However, to the best of our knowledge, none of research analyzed the tendencies of sustainable bioeconomy implementation in all EU countries, considering the changes in biomass extraction and the main determinant in applying the IPAT approach.
2.2. Efficiency of bioresource and the IPAT approach
Biomass renewable sources are not “freely” available (as opposed to wind and water) and have a long supply chain from planting, growing, harvesting, pre-treatment, and conversion (Rural Biomass Energy Book, 2020). Authors have acknowledged that the implementation of sustainable bioeconomy requires improvements in the productivity (or efficiency) of the bioresources (Koukios et al., 2017; Scheiterle et al., 2017; Bell et al., 2018), in almost all national bioeconomy strategies. In the literature, authors analyzed only the level of productivity. Brizga et al (2019) revealed that in Baltic Sea Region countries from 2011 to 2015, the productivity of bioresource changed differently. In Poland, productivity levels increased by 20 %. Meanwhile, in Finland, only by 0.3 % (Brizga et al., 2020). Liobikienė et al (2020) showed that considering bioeconomy sector, the land footprint productivity in EU countries differed as well. Therefore, the big challenge remains for policymakers in how to enhance the productivity level. However, it is not only enough to enhance the level of bioresource productivity. The evaluation on how productivity levels contribute to the changes in bioresource extraction is necessary to analyze as well. To the best of our knowledge, this aspect was not analyzed by previous researchers. In order to reveal how productivity level contribute changes in bioresource extraction, the IPAT approach is suggested.
The IPAT analysis was proposed in the 1970s by Ehrich and widely used to analyze the drivers for energy use, environmental pollution, resource consumption and efficiency (Steinberger and Krausmann, 2011; Schandl and West, 2012; West and Schandl, 2013; Fishman et al., 2015; Tian et al., 2017; Dong et al., 2017; Chiu et al., 2017; Roman-Collado et al., 2018). Therefore, this method is suitable to analyze the drivers of bioresource extraction as well. IPAT decomposition analysis reveals the contribution of changes in population (P), affluence (A) and technology (T) (or intensity level) to the changes in bioresource extraction. Tian et al (2017) stated that IPAT decomposition analysis encompasses two aspects of Environmental Kuznets Curve: scale (the population and economic growth) and technique effects, in our case – the reduction of bioresource intensity. Therefore, IPAT analysis shows whether the technologies or efficient enhancement offset the main driving forces of biomass extraction as population and economic growth (Fishman et al., 2015). Furthermore, this analysis is suitable for comparison analysis among countries and could contribute to a basis to spur mutual communication and cooperation among EU countries on the governance of sustainable bioresource extraction and improve the efficiency level (Baninla et al., 2020).
