This study aims to develop a supply chain model for SAF derived from unutilized logging residues across Georgia, a prominent forestry state located in the southern region of the United States. We employed a mixed-integer linear programming (MILP) model to minimize the total discounted cost of the SAF supply chain using the Ethanol-to-Jet (ETJ) production pathway over ten years of operation. Three SAF demand scenarios were selected, i.e., meeting 20 % (high), 10 % (medium), and 5 % (low) of total SAF demand at the Hartsfield-Jackson Atlanta International Airport. Results indicate a unit production cost of US $1.92 L⁻¹, US $2.03 L⁻¹, and US $2.25 L⁻¹ for the high, medium, and low demand scenarios, respectively. Over a period of ten years, to produce 3.74, 1.87, and 0.94 billion liters of SAF in scenarios A, B, and C, respectively, 38.5, 19.2, and 9.6 million Mg of logging residues are required. The capital investment and operating cost at biorefineries accounted for an average of 77 % and 22 % of the total unit cost, respectively, across scenarios. The GHG intensity of the SAF was 767 g CO₂e L⁻¹ on average across scenarios, providing about 70 % of carbon savings relative to CAF. The supply chain model suggested 54 biomass processing units (BPUs) and 13 bio-refineries across Georgia under the high demand scenario, 27 BPUs and 7 bio-refineries under the medium scenario, and 14 BPUs and 4 bio-refineries under the low SAF demand scenario. Our study is expected to provide new insights into the emerging market of SAF in Georgia and beyond.</div></div>","PeriodicalId":12451,"journal":{"name":"Forest Policy and Economics","volume":"170 ","pages":"Article 103401"},"PeriodicalIF":4.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142889294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach emphasized three power features, namely, coercion, (dis)incentives and dominant information. After a decade of empirical validation, it is imperative to take stock of its application while reflecting on potential “missing power features” in the ACP. In this paper, we propose four “missing power features” in the ACP theoretical approach. These include <em>social cohesion</em> (the societal glue), <em>geography</em> (landscape remoteness), <em>process</em> (the switch in the roles of potentates and subordinates in the same transaction), and <em>convictions</em> (narratives that steer an us-versus-them discourse). A fifth overarching missing element is <em>time</em> – here we argue that all power features in the ACP have a temporal dimension. The paper draws from theoretical reflections in other power studies, and a systematic review of 61 empirical literature on power in forest management institutions. To verify empirical trends from the systematic reviews through a contemporary example, qualitative data generated through the interview of key informants (<em>n</em> = 51), experts (<em>n</em> = 12), and focus group discussions (<em>n</em> = 10) from two cases in Central Africa is provided. Analysis of articles selected through systematic reviews and own empirical data allows us to draw the following conclusions: Firstly, 88 % of the reviewed papers captured the four missing power features with <em>social cohesion</em> and <em>geographical remoteness</em> dominating the literature (67 %). Secondly, empirical insights from the two cases in Central Africa confirmed the recurrence of <em>social cohesion</em> linked to ties with forest-related livelihood strategies, and <em>geographical remoteness</em> which enhances insecurity. Thirdly, conservation interventions are also shaped by the power and potency of <em>process</em>, indicating a role switch between the potentate and subordinate within the same transaction, and convictions linked to people's heritage. While <em>process, social cohesion and convictions</em> presents a useful opportunity for an actor-cum-institutions theoretical framework, geography elucidates the scale dimension which should be clarified. We suggest the incorporation of these power features with time standing as an overarching power feature.</div></div>","PeriodicalId":12451,"journal":{"name":"Forest Policy and Economics","volume":"170 ","pages":"Article 103395"},"PeriodicalIF":4.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142823280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This gap may introduce biases in comparative analyses of forest management models. This paper provides new evidence to evaluate China's government regulation model from a welfare perspective. First, we construct a material deprivation index (MDI) of forestry worker families based on a new individual-level household survey data collected from 56 state forest enterprises (SFEs) across three provinces in China. Second, combined with historical enterprise-level attrition data in SFEs, we find that, during the period of China's Natural Forest Protection Program, the “only-out, no-in” staff-reduction policy alleviated the material deprivation of forestry worker families. Various identification strategies including the instrumental variable method have confirmed the above causal relationship. Third, we further divide the MDI into three subindexes: quality of life, living environment, and social relations. We find that the cumulative staff-reduction scale has negative causal effect on reducing forestry worker families' material deprivation in terms of the second subindex, but has no effect in terms of the first and third subindexes. Lastly, when the sample is divided into two groups—households living on the mountain and down the hill—the negative causal effect exists only for the latter group. These results update the empirical literature on government regulation model effectiveness and provide significant references for comparative studies on forest management model diversity.

The buffers protect the integrity of aquatic ecosystems and support resilience to rising temperatures and severe storms due to climate change. A hedonic study using 18,782 property sales was conducted to estimate the value of riverfront land and forested riparian buffers along the New and Watauga Rivers in North Carolina. Property owners place a significant value on river frontage and the associated amenities – 30 % of a riverfront property value is attributable to the river frontage, about $133,653 of a mean property value of $445,510. Owners of river-front properties value forested riparian buffers but there is a catch, they do not want all the riparian buffer on their land forested. Property sale prices increase as the percentage of the riparian buffer that is forested increases and prices are maximized at 40 % tree cover. At 40 % tree cover, 37 % property sale prices are attributable to riparian tree cover. However, with 100 % tree cover property values are reduced by about $175,000 relative to an average priced property with no riparian tree cover. The results can help government agencies and NGOs interested in riverine ecosystem resilience in the face of development and climate change to motivate revegetation of riparian buffers with limited tree cover; it is in the financial, and esthetic, interest of landowners to increase the forested portion of their riparian buffer. If extensive tree cover is desired, say greater than 50 % forested, landowner education and revegetation cost-sharing programs are unlikely to provide sufficient incentives to garner landowner participation and more sophisticated programing is required.</div></div>","PeriodicalId":12451,"journal":{"name":"Forest Policy and Economics","volume":"170 ","pages":"Article 103406"},"PeriodicalIF":4.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142889246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Respondents view the future implementation of adaptation measures as more feasible and effective than present implementation. Managers of conifer forests see more opportunities for implementing measures than managers of non-coniferous forests. This may be ascribed to the many measures currently being applied in countries with even-aged, non-site-adapted vulnerable coniferous forests. Furthermore, measures that predominantly increase resilience against bark beetle outbreaks and windthrow events are viewed more effective in coniferous forests, where these events are more frequent. Softwood processing experts generally consider implementing measures at processing facilities as less feasible and effective than hardwood processing experts. This may be due to the benefits gained by some softwood value chain segments from lower roundwood prices (which also applies to the lower-quality segments of hardwood processing), the more diversified raw material base in the softwood value chain and in secondary and tertiary processing facilities, and the hardwood industry's dominant reliance on high-quality wood, which cannot be harvested prematurely. Policy implications include prioritising measures with high effectiveness and resolving barriers to their feasibility. The findings highlight the need to invest in infrastructure and transition to mixed-species forests to create and manage climate-resilient forests effectively.

Our survey (analysis of 599 responses) was targeted on forest owners who had experienced biodiversity conservation related restrictions under involuntary conservation and who owned forest properties with significant biodiversity values. Our results suggested that owners of small forest properties under 5 ha, who are less financially dependent on forestry income and lack forestry education, as well as female forest owners, are more positive towards biodiversity conservation measures. Our results showed that most forest owners were not ready to accept substantial forestry restrictions. However, they would be ready to accept minor forestry restrictions such as no felling during bird breeding season and obligation of retention of a greater number of ecologically important trees and deadwood. Most forest owners considered the existing compensation system (annual payments) to be unfair.

Our estimates show that a 10 % increase in FDI is associated with a 0.86 % increase in patent applications, a smaller effect than in other industries. In particular, we examine how this positive effect of FDI on innovation is affected by the specific production and layout features of the forest products industry. We find that this effect is greater in regions rich in forest resources and non-coastal areas. Additionally, enterprises in this industry often focus on strategic innovations, such as product design, rather than substantial technological change, with innovation priorities differing across sub-sectors. Mechanism analyses reveal that FDI promotes innovation in forest products enterprises by increasing R&amp;D investments, optimizing the marketing environment, and alleviating financial constraints. Extended analyses indicate significant spillover effects of FDI-driven innovation across the industry, especially between the upstream and downstream segments of the supply chain.
