摘要

整个美国西部中山区的许多土地管理者都会定期疏伐木质生物量,以降低林分密度,从而减少发生严重野火的风险。将生物质废料(如间伐后的木屑)热解成生物炭有助于固碳,从而减缓气候变化并改善土壤健康。然而,在整个山间西部,没有足够的生物炭设施来处理从疏伐中获得的大量木质生物质。通过介绍新墨西哥州的案例,本研究提供了一个空间明确的框架,该框架根据变量的空间维度解释变量之间的关系,利用生物质可用性、野火风险、市场、土壤条件和道路网络等各种因素来确定新生物炭生产设施的最佳位置。目前已确定了几个适合建设生物炭生产设施的地点,但所需数量取决于设施容量和原料运输距离。这项研究的结果有助于在该地区建立几个中型或单一的集中式生物炭生产设施。此外,生物炭生产设施的建立还能激励林业承包商和土地所有者加快新墨西哥州过密森林的疏伐作业。最后,新墨西哥州还可以作为一个典范,供西部中山区的其他地区使用,以促进生物炭设施和生产规模的扩大。

Identifying optimal locations for biochar production facilities to reduce wildfire risk and bolster rural economies: A New Mexico case study

Many land managers throughout the Intermountain West practice periodic thinning of woody biomass to reduce forest stand density and thereby reduce the risk of high severity wildfire. Pyrolyzing biomass wastes, such as slash from thinning, into biochar can help sequester carbon to mitigate climate change and improve soil health. However, there are insufficient biochar facilities to process the amount of woody biomass available from thinning throughout the Intermountain West. By presenting a case of New Mexico, this study provides a spatially explicit framework, which explains relationships among variables based on their spatial dimension, to utilize a variety of factors such as biomass availability, wildfire risks, markets, soil conditions, and road networks to identify optimal location(s) for new biochar production facilities. Several locations suitable for biochar production facilities have been identified, but the number needed depends on facility capacity and feedstock hauling distances. Findings from this study can help establish several medium-size or a single centralized biochar production facility(ies) in the region. Furthermore, establishment of biochar production facilities can incentivize forestry contractors and landowners to expedite thinning operations in densely overstocked forests of New Mexico. Finally, it can serve as a model that other regions in the Intermountain West can use to facilitate scaling of biochar facilities and production.

期刊介绍: Forest Policy and Economics is a leading scientific journal that publishes peer-reviewed policy and economics research relating to forests, forested landscapes, forest-related industries, and other forest-relevant land uses. It also welcomes contributions from other social sciences and humanities perspectives that make clear theoretical, conceptual and methodological contributions to the existing state-of-the-art literature on forests and related land use systems. These disciplines include, but are not limited to, sociology, anthropology, human geography, history, jurisprudence, planning, development studies, and psychology research on forests. Forest Policy and Economics is global in scope and publishes multiple article types of high scientific standard. Acceptance for publication is subject to a double-blind peer-review process.
