Abstract
In few years the production and consumption of renewable energy sources is strongly increased at international level and this is related to the policies to fight climate changes and promote fossil fuels substitution. Biomass is the primary source of renewable energy in Europe, and the second one in Italy. Most expectations to agro-forestry biomass as energy sources are connected to their environmental benefits and the potential positive impact in the local social-economic development. In order to promote a rationale use of locally available biomass, there is a strong need to promote studies and researches about specific areas taking into account their physical and socioeconomic characteristics. The aim of this study is to identify and assess the agro-forestry resources of the Regional Natural Park of Bracciano-Martignano territory. The study and its reasults have an important implication on the Natural Park goals by indirectly helping the promotion of the economic and social development of the Park, compatibly with the conservation of the territory (LR n. 36 of 11.25.1999).
Therefore, this study would like to provide a clear assessment of the biomass potential from the agro-forestry sectors that can be exploited to produce energy. In particular, it has been paid attention to the biomass which currently do not have any other technically and economically more convenient use: residues from woodland and agricultural residues (pruning, straw). The AIGR-ENEA methodology, reviewed and updated, has been used to estimate local gross and net biomass potential. To improve results reliability local surveys and inspections on site have been carried out with the aim to define local parameters for residues calculation. Globally in the park area we estimated that, on an average year, we could exploit about 17 kilotons of biomass (dry matter) and that a local thermal use seems to be the best option.
This study could help to raise the awareness of the public opinion and decision makers about the possibilities offered by the agro-forestry sector as a source of biomass for energy use and provide a better knowledge of biomass availability to support local policies to enhance local development. Furthermore, in this study it was performed a preliminary analysis on total forest biomass and the carbon stocks. Indeed, it was possible to make a first step towards the quantification of biomass in the chestnut forest of the park by using a module implemented within the project KEI-EXTENSION, based on model 3-PG. The first stage of the biomass estimation, introduced in this study provide important information on the basis of which it could be possible to evaluate current and future carbon stocks and better evaluate the exploitation level of local forests for energy uses that do not compromise the carbon stock.
