“…The optimum management strategy for these bioenergy plantations needs to be identified through empirical data from field trials for aspects such as harvesting cycle and method, proportion of residue removal, irrigation system, chemical inputs (amount and frequency), and other ancillary human activities such as grazing and logging. Field trials have started in North America and Europe for bioenergy plantations (e.g., SRC) (Bouget et al, 2012;Langeveld et al, 2012;Lattimore et al, 2013), but few have been conducted in Australia. Moreover, management strategies for bioenergy crop production on 'underutilised agricultural land' are not well known, but are expected to require higher resource inputs than productive agricultural land.…”

Land use change effects have emerged as an important area of global bioenergy sustainability policy and research. 'Underutilised agricultural land' has been previously proposed as a potential option for future bioenergy feedstock production that may minimise the environmental and social challenges of land use change. However, this has not been well tested to date. Our research aims to evaluate whether conversion of these lands to selected bioenergy crops can lead to favourable environmental outcomes for eight indicators related to water quantity and quality, and terrestrial biodiversity. A spatially explicit evaluation framework based on GIS was developed to quantify the environmental effects of land use change. The land use change scenarios, established in a case study region in subtropical Queensland, Australia, were for the production of Pongamia and two native eucalypt species (Spotted gum and Chinchilla white gum) on (i) existing 'underutilised' open grazing areas, (ii) existing 'underutilised' forested grazing areas, and (iii) all available 'underutilised agricultural land' in the case study catchment, under both low and high management intensity. We found that environmental benefits can be gained in scenarios where (i) open grazing areas (e.g., pastures) were used; (ii) native woody perennial bioenergy crops were planted; and (iii) the new plantations were under low management intensity. Other scenarios resulted in reduced environmental outcomes. The results flagged the importance of careful planning and management strategies, and the need for future bioenergy policy to provide more detailed prescriptions concerning land use planning and management if 'underutilised agricultural lands' are used for future bioenergy crop production.

“…While a direct comparison of these products was not the intent of this article, our findings demonstrate pellets' dependence on this assumption by acting as a small-C (case 1) or large-C source (case 2) with or without this assumption. As countries begin claiming the climate reductions of HWPs (UNFCCC 2003), certification of forest practices in MPB stands will be required in meeting a sustainable certification standard (Masters et al 2010), as well as meeting climate mitigation objectives (Lattimore et al 2013). With a potentially diminished growth rate of timber stocks, as seen in the worst-case scenario in Metsaranta et al (2011), C-neutral forestry may in fact not be met at the landscape scale (Holtsmark 2012).…”

“…These challenges include the setting of certification standards (Masters et al 2010) and climate mitigation objectives (Lattimore et al 2013) for MPB forests. The challenges in managing harvested wood products include the depth (i.e., material versus product approach) and breadth (i.e., short-versus long-term) of C modeling.…”

British Columbia (BC)' s forests and wood products industry face tremendous adversity in the face of the mountain pine beetle (MPB; Dendroctonus ponderosae) epidemic. The death and decay of one of BC' s leading merchantable tree species (lodgepole pine; Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) threatens both the sustainability and climate mitigation opportunities in BC forests. Our study investigates the potential for carbon (C) storage in wood products in the post-epidemic phase of the MPB outbreak. In particular, we contrast the C-balance implications of converting MPB timber into long-lived wood products (i.e., lumber) (scenario 1) versus softwood pellets for bioenergy (scenario 2). Our findings highlight the importance of the C-cycle neutral assumption in determining the net C-balance of lumber versus pellets. Timber harvests for lumber resulted in a net C storage with this assumption (case 1), and net C emissions without this assumption (case 2). With uncertainty surrounding the future C-balance of BC forests, the current assumption of biomass-derived emissions being completely C-neutral may need to be re-evaluated.Keywords: mountain pine beetle, carbon, harvested wood products, carbon-neutral, lumber, pellets, life cycle assessment résumé Les forêts et l'industrie des produits forestiers de la Colombie-Britannique ont à surmonter le déchaînement incomparable de l' épidémie du dendroctone du pin (Dendroctonus ponderosae). La mort et la décomposition de l'une des espèces commerciales les plus importantes de la C.-B. (le pin lodgepole, Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) menacent autant la durabilité des forêts de la province que les possibilités d'atténuation des changements climatiques. Notre étude s' est penchée sur le potentiel de stockage du carbone (C) au cours de la phase post-épidémie de l'infestation du dendroctone du pin. Nous comparons plus particulièrement les conséquences de la neutralité du C par la conversion du bois décimé par le dendroctone sous forme de produits forestiers de longue durée (par ex., bois de sciage) (scénario 1) par rapport à des granules de résineux pour la production de bioénergie (scénario 2). Nos résultats soulignent l'importance de l'hypothèse du cycle neutre du C pour déterminer le solde net du C du bois de sciage comparativement aux granules. Les récoltes de bois de sciage ont entraîné un stockage net de C que ce soit selon (cas 1) ou sans (cas 2) cette hypothèse, tandis que les allocations de récolte pour des granules ont entraîné des émissions de C dans les cas 1 et 2. En tenant compte de l'incertitude entourant la neutralité future du C dans les forêts de la C.-B., l'hypothèse actuelle de neutralité complète du C issu des émissions en provenance de la biomasse pourrait devoir être réévaluée.Mots clés : dendroctone du pin, carbone, produits forestiers récoltés, neutralité du carbone, bois de sciage, granules, évalua-tion du cycle de vie

“…Dendromass input (white acacia) represents 1.73% of the whole dendromass in the forests of Slovakia (for year 2010), which represents an area of 33,308.91 hectares. Important feature of dendromass is its moisture (Lattimore et al 2013). When fuel wood is properly dried, its net calorific value is increased (Singh et al 2014).…”

Jobbágy J., Krištof K., Andacký M. (2016): The effectiveness of heating of housing unit by renewable energy source. Res. Agr. Eng., 62 (Special Issue): S34-S43.The paper is aimed at pointing out possibilities of using of dendromass for heating. The object of interest was heating of housing units with 75.27 m 2 of total area. The average value of dendromass moisture was 17.71%. The inserted fireplace Nordica Focolare 70 with a nominal output of 9 kW was used as a heat source. For temperature measurement, a non-contact infrared thermometer GM 900 was used. The total heat loss transferred through walls of housing unit (heat loss through thermal bridges and ventilation losses) were calculated at the value of 176.26 W/K. Based on the results of samples moisture the net calorific value of one kilogram of burned fuel wood was determined (14.791 MJ kg). The amount of thermal energy which is necessary to supply by the heating system for the whole heating period was 14,199.18 kWh. The weight of raw fuel wood was 5,450.97 kg (at moisture of 30%), dried at 17.71% (4,636.87 kg). Price of raw fuel wood of acacia for the year under evaluation was 64.80 €/m 3 (the required amount of raw fuel wood for heating period was 10 m 3 ). Total costs for the heating season was thus 648 €. The price of heat transmitted by the fireplace inset Nordica Focolare 70 inserted into heating system using fuel wood (white acacia) with 17.71% of absolute moisture was 0.045636 €/kWh.
