“…Todavia, essa utilização ainda é negligenciada em diversas partes do mundo (Kalt et al, 2019) ou altamente dependente do incentivo à descarbonização da matriz elétrica, como em alguns países europeus (Mesfun et al, 2018). Dentre as múltiplas áreas, alguns trabalhos apresentaram integração com as análises ambientais (AA+EF+PD), Aruga, Murakami, Nakahata, Yamaguchi & Yoshioka (2011) destacaram que o uso da bioeletricidade florestal em pequenos sistemas de combustão direta ou de gaseificação apresentam redução significativa nas emissões comparadas aos combustíveis fósseis. Steubing et al (2014) também apontaram que plantas de até 140 MW apresentam redução significativa nas emissões de CO2 e CHF, sendo a conversão, o processo de maior emissão de poluentes, seguido do custo de transporte de insumos e de colheita.…”

Este artigo analisou as evidências da análise espacial na bioenergia florestal para geração de eletricidade, no período de 1980 a 2019. Realizou-se uma análise bibliométrica e revisão sistemática de literatura utilizando os bancos de dados da ISI Web of Knowledge e Scopus. Os resultados mostraram que no período estudado houveram 28 publicações distribuídas em artigos científicos (92,85%) e em artigos de revisão (7,14%). Na análise de conteúdo, destacaram três áreas principais presentes na literatura, foram elas: ambiental, econômico-financeira, e disponibilidade de biomassa. O primeiro estudo foi publicado em 1989, tratando do uso energético biomassa florestal na Zâmbia; todavia observou-se aumento significativo das publicações durante a década de 2010, sendo os Estados Unidos o país com maior contribuição (11 trabalhos). Observou que as análises espaciais podem contribuir como ferramenta de apoio para tomadores de decisão, fornecendo orientação explícita sobre custos, eficiência e localizações ideais para o uso da bioeletricidade florestal.

“…Thinning is performed for economic reasons (e.g. Aruga et al, 2013) or to promote stand health (e.g. Ronnberg et al, 2013) and would reduce tree density while leaving the average stem biomass initially unaffected, resulting in a shift to the right for affected stands in Fig.…”

A stand-alone tree demography and landscape structure module for Earth system models: integration with inventory data from temperate and boreal forests

Abstract. Poorly constrained rates of biomass turnover are a key limitation of Earth system models (ESMs). In light of this, we recently proposed a new approach encoded in a model called Populations-Order-Physiology (POP), for the simulation of woody ecosystem stand dynamics, demography and disturbance-mediated heterogeneity. POP is suitable for continental to global applications and designed for coupling to the terrestrial ecosystem component of any ESM. POP bridges the gap between first-generation dynamic vegetation models (DVMs) with simple large-area parameterisations of woody biomass (typically used in current ESMs) and complex second-generation DVMs that explicitly simulate demographic processes and landscape heterogeneity of forests. The key simplification in the POP approach, compared with second-generation DVMs, is to compute physiological processes such as assimilation at grid-scale (with CABLE (Community Atmosphere Biosphere Land Exchange) or a similar land surface model), but to partition the grid-scale biomass increment among age classes defined at sub-grid-scale, each subject to its own dynamics. POP was successfully demonstrated along a savanna transect in northern Australia, replicating the effects of strong rainfall and fire disturbance gradients on observed stand productivity and structure. Here, we extend the application of POP to wide-ranging temporal and boreal forests, employing paired observations of stem biomass and density from forest inventory data to calibrate model parameters governing stand demography and biomass evolution. The calibrated POP model is then coupled to the CABLE land surface model, and the combined model (CABLE-POP) is evaluated against leaf–stem allometry observations from forest stands ranging in age from 3 to 200 year. Results indicate that simulated biomass pools conform well with observed allometry. We conclude that POP represents an ecologically plausible and efficient alternative to large-area parameterisations of woody biomass turnover, typically used in current ESMs.

“…Because forests are almost 45 to 55 years old, many thinning operations were conducted and very few final felling operations were conducted (Figure 3) because of the low profitability of such operations with regeneration expenses on the current Japanese forestry situation (Aruga et al, 2013b). Given delays in thinning operations -a serious problem for man-made forests in Japan -in …”

“…This study first examined the system to aggregate neighboring subcompatments and compared the supply potential and availability of logging residue from profitable stands with those for subcompartments in Nasushiobara city in Tochigi Prefecture, where an agrarian organization was willing to conduct thinning operations and extract thinned wood for biomass power generation in cooperation with the Forest Owners' Co-operative (Aruga et al, 2013b). This supply potential and availability were estimated using forest management records for several fiscal years between 2005 and 2010 to examine the trends, particularly, with a new tax -Tochigi no genkina moridukuri kenmin zei-to make forests healthy, along with subsidies for thinning operations, that started in April 2008 (Tochigi Prefectural Government, 2010a).…”

Abstract:Using forest management records from 2005 to 2010, this study compared supply potentials and available logging residue amounts from profitable aggregated stands in Nasushiobara city in Tochigi prefecture with those from profitable subcompartments. Supply potentials from precommercial, commercial thinning, and final felling operations were 39,584 tons, 10,376 tons, and 3,385 tons, respectively. Available amounts at 3,000, 6,000, and 10,000 yen/ton were estimated to be 2,920 tons, 3,495 tons, and 13,334 tons from profitable subcompartments and 2,628 tons, 5,143 tons, and 29,940 tons from profitable aggregated stands, respectively. The available logging residue amounts were increased according to logging residue prices and for aggregated stands. Considering the subsidy, available amounts at 3,000, 6,000, and 10,000 yen/ton were increased to 20,526 tons, 34,981 tons, and 45,175 tons, respectively. The annual available logging residue amounts with a 3,000-yen/ton logging residue price were 3,421 tons/year over the expected demand of logging residues of 2,000 tons/year. Furthermore, the annual available logging residue amounts with a 6,000-yen/ton and a 10,000-yen/ton logging residue price were 5,830 tons/year and 7,529 tons/year over the expected demand for woody biomass of 5,000 tons/year. The supply potential and availability of logging residues, particularly from precommercial thinning operations, were significantly increased from 2009 because of the new tax that started in April 2008.
