Tree parameter estimation with iPhone point cloud data using multiple algorithms

ABSTRACT LiDAR technology introduced the possibility of indirectly estimating various tree parameters. In 2020, Apple incorporated LiDAR sensors into their iPhone 12 Pro. This brings an opportunity to make data collection and plot scanning incredibly convenient. The main aim is to search for a tool and software to estimate the most accurate Diameter at Breast Height (DBH) for individual trees. Therefore, this study focuses on using an iPhone 12 Pro for data collection of individual trees. The performance of three software tools (ForestScanner, rTLS, RANSAC) for the estimation of DBH with field-estimated DBH was compared. The investigation of the significance of the estimation of DBH for each tree species was performed using the three algorithms. In this context, the scanning of 123 trees comprising six species: pine, oak, beech, hornbeam, spruce, and fir was done. DBH was estimated of the scanned tree point cloud using a built-in algorithm of ForestScanner application in the iPhone 12 Pro, RANSAC (CloudCompare plugin), and rTLS (an R-based package). In this study, ForestScanner showed the best results. Therefore, ForestScanner can be used as a reliable tool for measuring DBH. Inferences confirmed by ANOVA and Tukey post-hoc tests show that species significantly influence DBH. Accurate DBH estimation is crucial, and using lightweight devices like the iPhone can revolutionize the forest inventory sector in terms of the estimation of DBH.

Soil greenhouse gas fluxes partially reduce the net gains in carbon sequestration in mangroves of the Brazilian Amazon

There is interest in assessing the potential climate mitigation benefit of coastal wetlands based on the balance between their greenhouse gas (GHG) emissions and carbon sequestration. Here we investigated soil GHG fluxes (CO2 and CH4) on mangroves of the Brazilian Amazon coast, and across common land use impacts including shrimp farms and a pasture. We found greater methane fluxes near the Amazon River mouth (1439 to 3312 μg C m−2 h−1), which on average are equivalent to 37% of mangrove C sequestration in the region. Soil CO2 fluxes were predominant in mangrove forests to the East of the Amazon Delta. Land use change shifted mangroves from C sinks (mean sequestration of 12.2 ± 1.4 Mg CO2e ha−1 yr-1) to net GHG sources (mean loss of 8.0 ± 3.3 Mg CO2e ha−1 yr−1). Our data suggests that mangrove forests in the Amazon can aid decreasing the net annual emissions in the Brazilian forest sector in 9.7 ± 0.8 Tg CO2e yr−1 through forest conservation and avoided deforestation.

Recognizing social forestry's role in bioenergy optimization through geospatial fuzzy-multicriteria analysis

Current bioenergy development has emphasized on degraded land, since the sustainability of bioenergy in the forest sector remains a subject of debate related with emissions and deforestation risk. Thus, this study aims to open new perspectives of how degraded land and social forestry can be potentially combined to significantly impact the energy transition and environmental-societal enhancement. Considering sustainability of Bali as a small island with its unique customary governance structure, a model of biomass energy optimization using geospatial fuzzy-multicriteria analysis was developed to select potential green energy source sites. Firstly, potential degraded land and social forestry were mapped to identify potential feedstock, then normalized using Euclidian Distance and Fuzzy Logic based on identified five sustainability criteria. They are availability of raw material, road, port, transmission, and demand proximities. Meanwhile, using identified three restriction criteria, i.e. protected area, slope and land-use restrictions, a restriction map was developed. The two maps were then integrated using Geospatial-based multicriteria analysis, fuzzy logic and Analytical Hierarchy Process (AHP) weighting method, to further identify potential green energy source map. The integration shown a significant increase of 60 % in land availability for bioenergy development. Results of study recognized potential 36,527 ha of degraded land; 21,671 ha of social forestry; and 40 optimal locations for bioenergy facilities, considering various spatial and temporal criteria. To conclude, the identified 120 social forestry sites in Bali involving 78,385 household provide opportunity to a community based socio-economic coupled with revitalizing environment efforts, which lead to massive net zero emissions community participation. Further, the integration of social forestry and degraded land should be highly recommended to policy maker in bioenergy development.

Strategic pathways for a bioeconomy with high value-added products: Lessons learnt from the Latvian forest sector

Climate change, the increasing global demand for food and feed and the loss of biodiversity, requires a shift towards a sustainable, innovative and knowledge-based bioeconomy. Simultaneously, the implementation of a strategic approach to the utilization of the sector and associated bioresources that aligns with the principles of sustainability represents a significant challenge. The aim of this study is therefore to develop a methodology for policy and decision makers to facilitate a knowledge-based bioeconomy policy planning framework. To map the development opportunities of the bioeconomy, a detailed analysis was conducted on the Latvian forest sector. This entailed an examination of the system's components within the sector, which involved the collection and analysis of statistical data, reports, and official information from forest sector stakeholders, with the objective of obtaining a comprehensive overview of Latvia's forest sector. Following the identification of the current enablers and constraints of the sector, a selection of niche products with high value-added for sector development was made. During group model building experts: (1) developed a SWOT matrix for the Latvian forest sector; (2) selected three wood-based high value-added products – textile from trees; particle board; natural thermal packaging; (3) elaborated SWOT/TOWS analysis to facilitate strategy development for the niche products. The developed methodology incorporates a synthesis of established scientific methods, including SWOT, TOWS, and AHP, with a bioeconomy system component analysis approach. The methodology therefore not only systematises the process of forest sector analysis, but also applies the findings to the development of sector development pathways aimed at shifting from low value-added to high value-added production. The innovation of the methodology lies not only in the combination of methods used, but also in the insights gained, which allow for a narrower product development perspective to be taken in order to understand the enablers and constraints of the sector and vice versa.

Two decades of stakeholder voices: Exploring engagement in Romania's FSC forest management certification

Stakeholders' engagement in forest management decision-making is a critical tool for enhancing the business acceptability of the forest sector, and the Forest Stewardship Certification (FSC) scheme proactively involves stakeholders in its implementation. Based on the stakeholder theory, this study examined stakeholder's engagement in the FSC forest management certification in Romania over the past two decades to identify the extent and inputs of their involvement in the process. Using in-depth content analysis and text mining techniques, we explored publicly available information from 209 public reports covering 45 forest management certificates. According to data available in 178 reports, the average number of stakeholders notified per audit was 50.7. However, response evidence was found in 128 reports, with an average of 1.2 responses per audit, suggesting a limited engagement in the process. Additional stakeholders' feedback was received as part of the on-site audits, with an average of 10.2 responses per audit. Given the inconsistencies in the reporting format between certification bodies, we set a structured framework to analyse the findings on stakeholders' engagement from different report sections. The employed analytical framework sheds light on stakeholder and legitimacy theories in forest certification. Our findings highlighted stakeholders' predominantly positive feedback tone, evenly distributed across all stakeholder types and the four analysis domains. Negative feedback accounted for only 9.4% of the findings, highlighting areas for improvement for certificate holders, companies in the timber supply chain and public authorities. This study's findings may assist FSC in refining its stakeholder engagement practices, contributing to enhanced participation and better risk mitigation of non-compliance with standard requirements.

The forest-water-nexus: A narrative construction of the (ir-)relevance of cooperation

Interlinkages between forest and water resources are changing with global warming, leading to an increased likelihood of severe disturbances such as floods and droughts. In order to develop responses to these changing interlinkages and their effects on local communities and ecosystems, scholars propose to increase interactions across the forest and water sectors. In Germany, however, the two respective sectors have been observed as institutionally and ideationally fragmented, showing very few signs of cross-sectoral cooperation. As local actors are most directly affected by global warming and struggle to adapt to its consequences, we argue that cross-sectoral cooperation is also relevant at the local scale. Against this background, it is our aim to investigate the local narrative constructions of the (ir)relevance of cooperation across the forest and water sectors. Based on semi-structured interviews and focus group discussions in six case study areas, we identify eight narratives which range from irrelevance (4), via partial relevance (2), to relevance of cooperation (2). Additionally, we elucidate a disinterest in cooperation among local water actors, compared to a narrative of urgency and fatalism among forest actors. Disinterest and urgency, however, furthermore differ regionally: Disinterest in cooperation is predominant in water abundant regions, whereas urgency is predominantly observed in regions of water scarcity. We contribute to conceptualizing disinterest as the rejection of a (common) problem possibly related to defend one's turf, and related both the urgency and fatalism narratives to the high affectedness within the forest sector.

Prospective impacts of windstorm risk on carbon sinks and the forestry sector: an integrated assessment with Monte Carlo simulations

Abstract Storms pose a significant threat to economic activities in the forest sector and introduce non-permanence risks for carbon stocks. Following escalating climate ambitions, understanding and addressing these risks becomes imperative. Uncertainties intrinsic to the storm phenomenon render this task complex. This study uses an integrated forest sector model to assess the economic and carbon impacts of storm regimes, emphasizing the importance of uncertainties through Monte Carlo simulation. From an economic perspective, we unravel complex interplays between the salvage and inventory effects of storms that lead to heterogeneous transfers of economic welfare across agents and space. Non-affected forest owners benefit from inflated prices, while affected owners’ recovery hinges on the magnitude of storm damage. From a climate perspective, storms significantly impact the forest sector’s carbon sink, with a high risk of falling short on mitigation objectives. In 25% of simulations, we observe a substantial 24% decrease in carbon sequestration. Our findings advocate for (1) conservative reliance on natural carbon sinks in national climate mitigation strategies toward net-zero, and (2) tailored risk-sharing insurance mechanisms for forest owners, providing a buffer against economic uncertainties arising from climatic disruptions.

Current expansions in the Brazilian timber market

The attractive financial returns from timberland investments in Brazil, particularly fast-growth tree plantations like pine and eucalyptus, have attracted multiple investors over the last decade. Among the countries with a competitive Pulp and Paper Industry (PPI), pulp and paper investors have expanded substantially in Brazil with new mills and planted areas. This paper presents a comprehensive investigation of the dynamics of the Brazilian pulp and paper industry forest sector in the past decade. We described the current macroeconomic and political environment in Brazil and the expansion of mills and timberland in Brazil. Brazil is, clearly, among the selective countries where a substantial expansion of the forest sector is possible. The regions like Mato Grosso do Sul have impressive scales of productivity and expansion. Other areas, like the states of Maranhão, Piaui, Tocantins and Bahia present potential to expand forest plantation, however, they are limited by weather constraints (extensive drought and fire seasons). Even well-known markets, like the South region of Brazil, have has opportunities to expansion subject to higher land prices. Brazil’s attractiveness for timberland investments is underscored by robust economic indicators and extensive natural resources. Yet, navigating the complexities of its political landscape remains a critical consideration for potential investors looking to capitalize on the country’s promising forestry sector.

Ecological and socio-economic factors influence stand biodiversity

Biodiversity is associated with functional protection, adaptation to external conditions, and ecosystem resilience. Therefore, maintaining forest ecosystems with high biodiversity is essential for improving resistance and resilience to disturbances. In addition to the ecological factors influencing forest ecosystems, various socio-economic factors associated with forests can influence the ecosystem. However, socio-economic impacts on forest biodiversity have rarely been addressed. In this study, we investigated whether tree species diversity (TSD) of forest stands varies with ownership status (national vs. private forests). In addition, selected ecological (stand characteristics, site conditions, and climate) and socio-economic (regional forest management sectors, population, forestry population, forest coverage, and forestry income) factors influencing TSD were determined using data from the National Forest Inventory in South Korea. National forests had higher TSD than private forests, reflecting differences in management objectives. Among ecological factors, stand structural diversity (SDivI) was the most influential in both national and private forests. Socio-economic factors, such as population, forest coverage, forest income, and forest management bodies, significantly influenced the TSD, although the impact was smaller compared to ecological factors. Our results suggest that securing stand growth and development is essential for increasing stand structural diversity, which leads to an increase in TSD. Furthermore, our study shows that socio-economic factors can influence forest conditions over time. To better understand the factors influencing the state of forests and manage forests sustainably in the future, collaborative research bridging ecological and sociological fields is necessary.

Food security effects of forest sector participation in rural Liberia

Forests can help rural households cope with food insecurity challenges in the face of climate change while also sequestering carbon and advancing other sustainability objectives in low- and middle-income countries (LMICs). As such, participation in the forestry sector can contribute to achieving the Sustainable Development Goals (SDGs), especially on hunger and food security (SDG 2) in forest rich, but economically poor areas of LMICs. However, analysis of the effects of forest sector participation on food security in such contexts remain limited. Here we estimate the effects of participation in forest-based activities like collection and processing of timber and non-timber forest products (NTFPs) on household food security in Liberia, the most forested country in West Africa. We applied endogenous switching poisson regression to data from 1408 households living in the proximity of forests included in Liberia’s 2019 national household forest survey to estimate the effect of forest sector participation on food security (in terms of reduction in the number of months households reportedly had insufficient food). Results show that forest-sector participation reduced the number of months households had insufficient food by 84% (about 2.7 months). Heterogeneity analyses show that NTFPs affected food security by 80% (about 2.5 months) compared to timber and wood products, which had a 66% effect size (about 2.1 months) on average. Our results provide new, national-scale evidence on the role of forests in enhancing food security in Liberia and suggest the importance of forest sector participation for food security and achieving SDG 2 more generally.

Bio-based resources: systemic & circular solutions for (agro)environmental services.

The global promotion of decarbonisation through the circular solutions and (re)use of bio-based resources (BBR), i.e. waste streams, notably from the agricultural, forest and municipal sectors has steadily increased in recent decades. Among the transformative solutions offered by BBR, biosolids (BS), biochars (BC), and bioashes (BA) specifically attract scientific attention due to their highly complex organo-mineral matrices, which present significant potential for recovery in the agro-/forest-ecosystems. These materials enhance various soil (i) chemical (pH, macro/micro nutrient concentrations, organic matter content), (ii) physical (porosity, water-air relations, compaction) or (iii) microbial (diversity, activity) properties. Furthermore, some of transformed BBR contribute to a multitude of environmental services such as the remediation of contaminated sites and wastewater treatment, employing cost-effective and eco-friendly approaches that align with circular economy/waste management principles, ultimately contributing to climate change mitigation. However, several challenges impede the widespread utilization/transformation of BBR, including technological limitations in processing and application, concerns about contamination (e.g., PAHs, PCBs, micro/nano plastics present in BS), toxicity issues (e.g., heavy metals in BA or nanoparticles in BC), and regulatory constraints (e.g., non-uniform regulations governing the reuse of BA and BS). Addressing these challenges demands an interdisciplinary and intersectoral approach to fully unlock the potential of BBR in sustainable decarbonisation efforts.

Typhoon-Induced Forest Damage Mapping in the Philippines Using Landsat and PlanetScope Images

Forests provide valuable resources for households in the Philippines, particularly in poor and upland communities. This makes forests an integral part of building resilient communities. This relationship became complex during extreme events such as typhoon occurrence as forests can be a contributor to the intensity and impact of disasters. However, little attention has been paid to forest cover losses due to typhoons during disaster assessments. In this study, forest damage caused by typhoons was measured using harmonic analysis of time series (HANTS) with Landsat-8 Operation Land Imager (OLI) images. The ΔHarmonic Vegetation Index was computed by calculating the difference between HANTS and the actual observed vegetation index value. This was used to identify damaged areas in the forest regions and create a damage map. To validate the reliability of the results, the resulting maps produced using ΔHarmonic VI were compared with the damage mapped from PlanetScope’s high-resolution pre- and post-typhoon images. The method achieved an overall accuracy of 69.20%. The accuracy of the results was comparable to the traditional remote sensing techniques used in forest damage assessment, such as ΔVI and land cover change detection. To further the understanding of the relationship between forest and typhoon occurrence, the presence of time lag in the observations was investigated. Additionally, different contributing factors in forest damage were identified. Most of the forest damage observed was in forest areas with slopes facing the typhoon direction and in vulnerable areas such as near the coast and hill tops. This study will help the government and forest management sectors preserve forests, which will ultimately result in the development of a more resilient community, by making it easier to identify forest areas that are vulnerable to typhoon damage.

Regulatory Capture by Corporations, Liberalization of Industrial Forest Sector and Deforestation in Indonesia

This study was motivated by the proliferation of forest management businesses for industrial interests. The issuance of the Industrial Plantation Forest policy has benefited pulp and paper corporations, which can be observed from both the rapidly increasing amount of production and the area used under corporate land management, which has even exceeded the amount of land used as regulated by existing regulations.There were three problems that this study seeks to address. Firstly, how had the Industrial Plantation Forest policies during the administrations of President Susilo Bambang Yudhoyono and Joko Widodo impacted P.T. Riau Andalan Pulp and Paper and local communities. Secondly, in what ways the policy had caused deforestation, especially on peatlands. Thirdly, how had the state, as the policy maker, maintained the social life of the communities to reduce conflicts that would disrupt production, particularly in Riau. This study show that the industrial plantation forest policies had benefited pulp and paper corporations, that rely on wood as raw materials, by providing various facilities and subsidies from the government. Susilo Bambang Yudhoyono's administration issued a lot more policies that benefited corporations than Joko Widodo's administration. Meanwhile, Joko Widodo in its first period administration attempted to make amendment by making a moratorium policy that temporarily suspended the issuance of new forest and land management permits. In addition, the Joko Widodo administration also introduced a social forestry policy that allowed communities to own forestry management land. However, during the second period of his administration, forestry policies, again, had benefited corporations, especially with the issuance of the Job Creation Law which gave rise to many protests from the public.Fred Block’s in his book “the Revising State theory” to the conclusion that the business community has a strong influence on the formation of state policy and that business people seek government’s assistance to support their profit-seeking activities through various policies. The policies are in the form of trade protection, subsidy programs, tax benefits, punitive treatment of strikers, contracts from the government, and so on. However, Block also believes that other than providing support to corporations to accumulate capital, the government must also maintain social stability both as a protection for business confidence and because the government wants to maintain its power. Social forestry policy, for example, is aimed at reducing social conflicts by providing access to communities with cultivated land to improve their welfare.

Climate change mitigation from increased paper recycling in Sweden: conserving forests or utilizing substitution?

Climate change mitigation by increased paper recycling can alleviate the two-sided pressure on the Swedish forest sector: supplying growing demands for wood-based products and increasing the forest carbon sink. This study assesses two scenarios for making use of a reduced demand for primary pulp resulting from an increased paper recycling rate in Sweden, from the present 72% to 78%. A Conservation scenario uses the saved primary pulp to reduce pulplog harvests so as to increase the forest carbon sink concomitant with constant overall wood product supply. In contrast, a Substitution scenario uses the saved primary pulp to produce man-made cellulosic fibers (MMCF) from dissolving pulp replacing cotton fiber, implying increased overall wood product supply. Our results suggest that utilizing efficiency gains in paper recycling to reduce pulplog harvests is better from a climate change mitigation perspective than producing additional MMCF to substitute cotton fiber. This conclusion holds even when assuming the use of by-products from dissolving pulp making and an indirect increase in MMCF availability. Hence, unless joint improvements across the value chain materialize, the best climate change mitigation option from increased paper recycling in Sweden would seemingly be to reduce fellings rather than producing additional MMCF.

The 2023 wildfire season in Québec: an overview of extreme conditions, impacts, lessons learned and considerations for the future

The 2023 wildfire season in Québec set records due to extreme warm and dry conditions, burning 4.5 million hectares and indicating persistent and escalating impacts associated with climate change. This study reviews the unusual weather conditions that led to the fires, discussing their extensive impacts on the forest sector, fire management, boreal caribou habitats, and particularly the profound effects on First Nation communities. The wildfires led to significant declines in forest productivity and timber supply, overwhelming fire management resources, and necessitating widespread evacuations. First Nation territories were dramatically altered, facing severe air quality issues and disruptions. While caribou impacts were modest across the province, the broader ecological, economical, and social repercussions were considerable. To mitigate future extreme wildfire seasons, the study suggests changes in forest management practices to increase forest resilience and resistance, adapting industrial structures to changes in wood type harvested, and enhancing fire suppression and risk management strategies. It calls for a comprehensive, unified approach to risk management that incorporates the lessons learned from the 2023 fire season and accounts for ongoing climate change. The studyunderscores the urgent need for detailed planning and proactive measures to reduce the growing risks and impacts of wildfires in a changing climate.

Legal regulation of the use of forest resources

The purpose of the study was to carry out a comprehensive analysis of the legislative framework in the field of forest resource management in Albania in the context of forest ecology, and species diversity, and to identify the main problems and prospects for sustainable development of the country’s forestry. The research methodology included the analysis of statistical data from the National Institute of Statistics of Albania on the structure of forest ecosystems and forms of their management. The results of studies conducted by international organizations such as the World Bank, Global Environment Facility, and Oikon d.o.o. were also used. The structure and composition of Albania’s forest resources, including those of natural and semi-natural origin, are analysed. The legal framework in the field of forest management in Albania is summarized. Different management structures for forestry land are characterized, with the identification of the specifics of use for different forms of ownership. The main problems of forest management are identified, including intensive exploitation of private forests, lack of subsidies and investments, as well as imperfect legislative regulation. Adaptation measures to increase the sustainability of Albania’s forests within the framework of the Albanian Forest Policy Document for the period 2019-2030 are substantiated. Strategic areas of development, such as the expansion of protected areas, the development of ecotourism and the attraction of green investments, are proposed. The study also emphasizes the importance of international cooperation for financial and technical support, which will facilitate the implementation of sustainable forest management practices and biodiversity conservation. The practical significance of the study is that these results can be used to develop strategic directions for the development of the forest sector in Albania, aimed at ensuring sustainable management and conservation of forest resources, which is a key factor for the country’s economic and environmental well-being

Environmental performance evaluation in the forest sector: An extended stochastic data envelopment analysis approach

This study addresses the global concern about undesirable outputs in the Forest Sector. We propose two innovative models, namely a directional weak disposable DEA model and an extended stochastic DEA model, to measure environmental efficiency. These models make a significant contribution to the field by specifically assessing the uncertain environmental efficiency of the forest sector. We validated our proposed models by conducting an empirical application using the United Nations Economic Commission for Europe (UNECE) forest sector dataset. The study examines important outputs such as above ground biomass stock, export unit prices of industrial roundwood, wood removals (desirable outputs), and CO2 emissions from wildfires (undesirable output). The results demonstrate that our novel stochastic weak disposability DEA model outperforms traditional approaches when the second scenario is applied. Specifically, the average technical efficiency (TE) score decreases to 0.92, and the number of efficient units reduces to 27, representing an approximate improvement of 55 %. Furthermore, the reduction rate of CO2 emissions is 4.09 % lower than the benchmark. Hence, our extended novel stochastic weak disposability DEA approach enhances the assessment of efficiency and inefficiency in decision-making units, contributing to the mitigation of risk and uncertainty. It also improves overall environmental performance in forest management.

Holistic analysis of factors influencing the adoption of agroforestry to foster forest sector based climate solutions

Improving adoption rate is vital for realizing agroforestry innovations' financial and environmental benefits including fostering climate change adaptation and resilience efforts. Adoption rate of agroforestry innovations improves through feedback-enriched interventions. Yet, the lessons that decades of adoption research generated were only partially incorporated for improving prospective development interventions. Among others, application of reductionist approaches and rarity of holistic perspectives were primary causes for poor understanding of adoption contexts and subsequent incorporation in development programs. This study shows how to undertake holistic adoption empirical analysis by constructing Bayesian Belief Network (BBN). Findings revealed that household contexts consistently, followed by innovation attributes and system level features, influenced likelihood of adopting agroforestry innovations. BBN allowed discovery of the contribution of each variable and layer of variables on optimized adoption rate. Hence results suggested which (groups of) variables to focus when aiming to improve adoption results. Further testing hypothetical policy intervention allowed comprehension of potential outcomes. The approach consolidated the view that comprehensive assessment is essential for inclusive and actual understanding of adoption influencing factors. The stratification of farmers from discretization feature of BBN allowed potential of addressing all groups of farmers (e.g., poor, medium, rich, male decision-making dominated families), evading earlier concerns of development interventions benefitting only better-off farmers. Our findings proved that holistic analysis can better foster agroforestry innovations adoption by allowing targeted interventions and hence consolidated the forest sectors climate solution opportunities for smallholder farmers.

BRAZILIAN SAWMILLS

The Brazilian Forest Sector is one of the most productive in the world with a good share of the Brazilian Gross Domestic Product. The furniture sector represents about 18% of the consumption of planted wood in Brazil and employs about 35% of the workforce in the sector. They are micro and small companies that generate a lot of jobs and fix the workforce in the countryside; however, the obsolete machinery and poorly trained workforce are responsible for the low productivity and profitability of the sector. The objective of this work was to identify the main problems and point out solutions for them. The main raw material and machinery indicators were identified, as well as corrective measures for each of them. The main conclusions were that the sector must organize itself in productive poles seeking the maximum specialization or the smallest number of products per establishment.
