“…Higher estimates (over a fourfold increase of current consumption) are conceived when advanced bioenergy technology availability is considered, allowing the conversion of readily accessible cheaper lignocellulosic biomass into liquid fuels and the deployment of BECCS to potentially allow for carbon dioxide removal in the power generation sector. However, the sourcing of primary biomass especially from the domestic forestry resource base must be carefully managed to achieve a net negative impact on global warming potential [66] The projections for future EU bioenergy demand range between 5 and 11 EJyr -1 in 2030 and 5-19 EJyr -1 in 2050. With regards to the sustainability aspects incorporated into the resource-focussed (supply) estimates, only the very strictest sustainability constraints under conditions in which bioenergy is not afforded the possibility of expansion into surplus land interfere with demand developments as envisaged within the EU roadmaps decarbonisation pathways.…”

Bioenergy is the EU's leading renewable energy source at present. Understanding bioenergy's contribution to the future EU energy mix is strategically relevant for mid to long term climate targets. This review consolidates recent projections of both supply and demand dynamics for EU bioenergy to 2050, drawing from resourcefocused, demand-driven and integrated assessment approaches. Projections are synthesised to identify absolute ranges, determine cohesion with policy and draw insights on the implications for the scale of development, trade and energy security. Supply side studies have undergone methodological harmonisation efforts in recent years. Despite this, due to assumptions on key uncertainties such as feedstock yields, technical potential estimates range from 9 to 25 EJyr-1 of EU domestically available biomass for energy in 2050. Demand side projections range between 5 and 19 EJyr-1 by 2050. This range is primarily due to variations in study assumptions on key influential developments such as economic competitivity of bioenergy, EU energy efficiency gains within the power sector, flexibility for meeting mitigation targets and technological portfolios. Upper bound technical supply estimates are able meet future demand wholly from the domestic resource base, holding the potential to reduce total EU primary energy import dependency 22% points from the current EU roadmap trajectory. However, due to part of this domestic resource base being deemed economically inaccessible or of insufficient quality, interregional imports are projected to increase from current 4% to 13-76%. Emergence of non-energy applications are projected to compete for at least 10% of the biomass needed to fulfil bioenergy demand in 2050.

“…Gough and Vaughan (2015) estimate it would require 500 Mha of land globally to grow the biomass needed to lock-up the required amounts of carbon. Furthermore, it is not entirely clear if all projects would deliver a net-negative carbon balance (e.g., Fajardy and Mac Dowell, 2017;Withey et al, 2019). In addition, the water footprint of energy crops is substantial when compared to other sources of energy (Gerbens-Leenes et al, 2009).…”

Recognizing that there are multiple environmental limits within which humanity can safely operate, it is essential that potential negative outcomes of seemingly positive actions are accounted for. This alertness to unintended consequences underscores the importance of so called “nexus” research, which recognizes the integrated and interactive nature of water, energy and food systems, and aims to understand the broader implications of developments in any one of these systems. This article presents a novel framework for categorizing such detrimental unintended consequences, based upon how much is known about the system in question and the scope for avoiding any such unintended consequences. The framework comprises four categories (Knowable and Avoidable; Knowable and Unavoidable; Unknowable and Avoidable, and Unknowable and Unavoidable). The categories are explored with reference to examples in both the water-energy-food nexus and planetary boundary frameworks. The examples highlight the potential for the unexpected to happen and explore dynamic nature of the situations that give rise to the unexpected. The article concludes with guidance on how the framework can be used to increase confidence that best efforts have been made to navigate our way toward secure and sustainable water, energy and food systems, avoiding and/or managing unintended consequences along the way.

“…In the context of renewable energy, wood biomass can be used for charcoal bioenergy production (Kongprasert et al 2019). The use of bioenergy from forest biomass shows a positive contribution to climate change mitigation (Withey et al 2019). Biomass production can also be used as an indicator to assess forest productivity (Zhang et al 2017).…”

Abstract. Tohirin, Suryanto P, Sadono R. 2021. Vegetation structure, aboveground biomass, and carbon storage of wono¸ local forest management in Gunungkidul, Yogyakarta, Indonesia, across three geomorphological zones. Biodiversitas 22: 3207-3218. Wono is local community-based forest management in Gunungkidul District, Yogyakarta. This land use has the potential to reduce carbon dioxide emissions through their carbon sequestration capacity as well as to produce renewable energy sources through wood biomass for charcoal and wood pellet. Since Gunungkidul is unique in terms of geomorphological characteristics, study on the vegetation structure, biomass estimation, and carbon storage of wono across geomorphological zones are important. Therefore, this study describes the vegetation structure of wono in three geomorphological zones of Gunungkidul District, as well as estimates the aboveground living biomass (AGB) and aboveground living carbon storage (AGC). The quadratic sampling technique was used to collect data for vegetation analysis with the size of the plots were 20 m x 20 m, 10 m x 10 m, 5 m x 5 m, and 2 m x 2 m for trees, poles, saplings, and seedlings, respectively. A total of 32 plots were established, consisting of 18 plots in Nglanggeran Village, 12 plots in Dengok Village, and six plots in Girisekar Village, each village representing geomorphological zones of Batur Agung, Ledok Wonosari, and Pegunungan Seribu, respectively. The AGB was performed non-destructively and estimated using referenced allometric equations. Furthermore, the AGC was calculated using a conversion factor of 0.47 from the obtained AGB. The results showed that the identified species at wono in Batur Agung, Ledok Wonosari, and Pegunungan Seribu zones were 13, 7, and 8, respectively. Swietenia macrophylla had the highest important value index (IVI) of 185.22% in the Batur Agung zone, while Tectona grandis was the most important species in both the Ledok Wonosari and Pegunungan Seribu zones with IVI= 238.27% and 178.60%, respectively. The biodiversity in these three zones was very low in terms of species diversity (H' < 2) and species richness (R1 < 3.4). The estimated AGB and calculated AGC in the Batur Agung, Ledok Wonosari, and Pegunungan Seribu zones were 210.96 ton ha-1 and 99.15 ton C ha-1, 73.58 ton ha-1 and 34.58 ton C ha-1, and 57.92 ton ha-1 and 27.22 ton C ha-1, respectively.
