Amazon forest on the edge of collapse in the Maranhão State,Brazil

The year 2019 in Brazil was marked by environmental setbacks, which catalyzed the increase of illegal deforestation and fire rates in the Brazilian Amazon. In the Amazon region of Maranhão state, original forest cover diminished from 25 % (24,700 km²) in 2016 to 24 % (23,967 km²) in 2019, and 6,038 km² of remaining forests were degraded by fires and/or illegal logging – processes related to high levels of violence against indigenous and rural communities. Almost half of all deforested areas in the region (36,060 km²) are considered a global restoration hotspot, however secondary vegetation remains unprotected and 8,294 km² were cleared between 2014 and 2018. Due to uncontrolled deforestation and fragmentation, Maranhão has no more forest core areas (outside protected areas) with the minimum size to ensure sustainable forest management practices for timber production. New policies at the state level must promote old-growth and secondary forest conservation and restoration. However, the trends point to the opposite direction: the Ecological-Economic Zoning (ZEE) allows the reduction of forest protection and the State Forest Policy reinforces federal legislation setbacks. The Amazon region of Maranhão state has forest aptitude, and forest and agroforestry product chains would bring social and environmental benefits, making them the best opportunity for sustainable economic development in the region. Therefore, the forest must be re-planted for the benefit of people and nature.     

Effect of conserving habitat for biodiversity on optimal management of non-industrial private forests in Florida

Healthy forests and enhanced habitat for wildlife is a growing concern among public and policy makers. These concerns have led to substantial interest in promoting various regulatory and voluntary compliance policies to further biodiversity on private forests. These policies, however, might result in additional cost to forestland owners. In this paper, we estimate the opportunity cost of adopting various biodiversity-friendly forest practices. We do this in the context of slash pine, a dominant commercial tree plantation species in Florida. Results suggest that prescribed burning, invasive species control, maintaining streamside buffer zones, and extending timber harvest beyond the optimal rotation age would significantly decrease the profitability of slash pine forestry. If the major objective of landowners is to maximize profits, results indicate that they are less likely to adopt these practices at socially desirable levels without a policy support. More specifically, results suggest that an annual payment of $38–83 per hectare is required for landowners to adopt these practices. The paper further argues that application of mere command-and-control approaches to implement these practices may result in conversion of private forests to other competitive land uses.     

Ecosystem services from community-based forestry in Nepal: Realising local and global benefits

Community-based Forestry (CBF) is now a popular approach for landscape restoration, forest management, biodiversity conservation and support for rural livelihoods worldwide. The Himalayan country Nepal has been at the forefront of CBF for over four decades, with almost 40% of the total population directly involved in protecting and managing more than 32% of the country’s forested land. However, in the past, the focus of CBF in Nepal was the provision of goods for local subsistence, and there has been limited analysis of the role of CBF in providing ecosystem services (ES) from restored forest landscapes. Based on material drawn from a literature review and a stakeholders’ workshop, this paper analyses changes in Nepalese forest policies to provide a more holistic framework for CBF that provides a wider range of ES and to potentially underpin payments for ecosystem services in Nepal. The analysis indicates that Nepal’s forest policy and practices are still dominated by a narrowly conceived notion of forest management that does not accommodate the holistic concept of ES. The study illustrates that CBF provides many ES from local to global benefits as result of forest restoration. For example, timber, firewood, food, and water have local importance, while climate regulation, flood/erosion control, and habitat improvement have global importance. Many innovative cases are emerging in the long journey of CBF in Nepal that demonstrate more diverse management strategies, new forms of tenure rights and autonomy in institutional spaces. These can potentially provide a catalytic platform for the wider adoption of the ES framework in CBF regimes, in order to focus and reward forest management more directly for the provision of services such as water, biodiversity, climate regulation and recreation. Consequently, this study discusses the issues and challenges that are impeding the implementation of the ES concept in Nepal and suggests some ways forward.

Analysing foregone costs of communities and carbon benefits in small scale community based forestry practice in Nepal

Reducing emissions from deforestation and forest degradation, conservation and sustainable management of forests and enhancement of forest carbon (REDD+) are considered to be important cost effective approaches for global climate change mitigation; therefore, such practices are evolving as the REDD+ payment mechanism in developing countries. Using six years (2006–2012) data, this paper analyses trade-offs between carbon stock gains and the costs incurred by communities in generating additional carbon in 105 REDD+ pilot community forests in Nepal. It estimates foregone benefits for communities engaged in increasing carbon stocks in various dominant vegetation types. At recent carbon and commodity prices, communities receive on average US$ 0.47/ha/year of carbon benefits with the additional cost of US$ 67.30/ha/year. One dollar’s worth of community cost resulted 0.23 Mg of carbon sequestration. Therefore, carbon payment alone may not be an attractive incentive within small-scale community forestry and should link with payments for ecosystem services. Moreover, the study found highest community sacrificed benefits in Shorea mixed broadleaf forests and lowest in Schima-Castanopsis forests, while carbon benefits were highest in Pine forests followed by Schima-Castanopsis forests and lowest in Rhododendron-Quercus forests. This indicates that costs and benefits may vary by vegetation type. A policy should consider payment for other environmental services, carbon gains, co-benefits and trade off while designing the REDD+ mechanism in community based forest land use practice with equitable community outcomes. The learning from this study will help in the formulation of an appropriate REDD+ policy for community forestry.     

Consequences of carbon offset payments for the global forest sector

Long-term effects of policies to induce carbon storage in forests were projected with the Global Forest Products Model. Offset payments for carbon sequestered in forest biomass of $15–$50/t CO₂e applied in all countries increased CO₂ sequestration in world forests by 5–14 billion tons from 2009 to 2030. Limiting implementation to developed countries exported environmental damage from North to South, as developing countries harvested more, decreasing their stored CO₂e. Substantially more CO₂e was sequestered by allocating a given budget to all countries rather than to developed countries only. As offset payments increased wood prices relatively more than they decreased production, timber revenues generally increased. In the few countries with timber revenues losses they were more than compensated by the offset payments.     

Sequester or substitute—Consequences of increased production of wood based energy on the carbon balance in Finland

Forests play an important role in mitigating climate change. Forests can sequester carbon from the atmosphere and provide biomass, which can be used to substitute for fossil fuels or energy-intensive materials. International climate policies favor the use of wood to substitute for fossil fuels rather than using forests as carbon sink. We examine the trade off between sequestering carbon in forests and substituting wood for fossil fuels in Finland. For Finland to meet its EU targets for the use of renewable energy by 2020, a considerable increase in the use of wood for energy is necessary. We compare scenarios in which the wood energy targets are fully or partially met to a reference case where policies favoring wood based energy production are removed. Three models are used to project fossil fuel substitution and changes in forest carbon sinks in the scenarios through 2035.Finnish forests are a growing carbon sink in all scenarios. However, net greenhouse gas (GHG) emissions will be higher in the medium term if Finland achieves its current wood energy targets than if the use of energy wood stagnates or decreases. The volume of GHG emissions avoided by replacing coal, peat and fossil diesel with wood is outweighed by the loss in carbon sequestered in forests due to increased biomass removals. Therefore, the current wood energy targets seem excessive and harmful to the climate. In particular, biodiesel production has a significant, negative impact on net emissions in the period considered. However, we did not consider risks such as forest fires, wind damage and diseases, which might weaken the sequestration policy. The potential albedo impacts of harvesting the forests were not considered either.     

Review - Roger A. Sedjo (2003): Economics of Forestry

Ashgate Publishing Limited, Gower House, Croft Road, Aldershot, Hants GU11 3HR, England (www.ashgate.com). 498 p. £ 100.00. ISBN 0-7546-2237-1 (hardback).Being one volume in the series of the International Library of Environmental Economics and Policy (T. Tietenberg and W. Morrison, gen. eds.), this book is a collection of some of the most significant journal essays in forest economics and forest policy. In compiling this volume, Roger Sedjo did a great service to the forest economics profession.This volume includes twenty-five essays originally published between 1849 and 1996 in a dozen journals, and one chapter from the Third Assessment Report of the International Panel on Climate Change (IPCC, 2001) which addresses the biological sequestration of carbon in terrestrial ecosystems. These are organized into four parts: the harvest rotation issue, timber supply, multiple-use and non-timber outputs, and global issues. An introduction essay to this volume, written by the editor, provides an overview of the major issues in forest resource management and discusses some the most important contributions to the forest economics literature.The eleven essays in the first part of the book provide a rather complete coverage of the most important contributions to the literature on optimal rotation age, which is a fundamental issue in forest management and forestry investment. Four of the essays (Faustmann 1849, Ohlin 1921, Bentley and Teeguarden 1965, and Samuelson 1976) address the basic formulation and interpretation of the optimal rotation model. Four essays (Löfgren 1985, Newman, Gilbert and Hyde 1985, Reed 1984, and Brazee and Mendelsohn 1988) extend the basic rotation model to examine the rotation age decision in the presence of deterministic trends and uncertainty in timber yield and price, respectively. Based on the Faustamnn rotation model, Klemperer (1976) and Chang (1982) examine the impacts of taxation on forest value and on the optimal rotation age. Koskela (1989) provides a detailed analysis of the impacts of taxation on timber harvest decisions under price uncertainty. What I feel missing in this part is a comparative statics analysis examining the impacts of changing economic parameters on the optimal rotation age.Part II includes five essays on economic analysis of long-run timber supply. Clawson (1979) reviews the historical development of forest resource and forest utilization in the United States. Vaux (1973) examines the long-run potential supply of timber from forest plantations in California. Berck (1979) investigates the difference in harvesting behavior between private forest owners and public managers. Lyon (1981) and Lyon and Sedjo (1983) examine the optimal exploitation of old-growth natural forests and the transition to steady state. While these essays all focus on the long-run timber supply in the United States, the methods developed and used in these papers could be applied for any other region. The exploitation of old-growth natural forests and the long-term availability of timber have been without doubt two major concerns in the United States. In many parts of the world, however, concerns about timber supply in the short-run have also had great influences on the development of forest policy. It would have been appreciated if a couple of essays addressing the short-run supply of timber had been included.Part III contains three essays dealing with the problem of multiple-use forest management. Gregory (1955) develops an economic framework for multiple-use management based joint production theory. Hartman (1976) examines the multiple-use rotation age decision. Swallow, Parks and Wear (1990) investigate the problem of non-convexities involved in multiple-use rotation age decisions. The merits of these essays lie in that they use rather simple models to demonstrate the importance of incorporating non-timber benefits in forestry decisions and the complexities of the multiple-use problem. In his 1976 essay, Hartman points out that in many situations management practices applied to one stand affect the value of non-timber outputs derived from the adjacent stands; such interdependence needs to be incorporated into multiple-use decision analysis. I certainly would like to find in this volume one or two essays examining the impacts of stand interdependence on the optimal decision. Another important issue in multiple-use management, which is not covered in this volume either, is the valuation of non-market priced outputs and services. Yet I believe that this omission is well motivated, for there are two separate volumes in this series devoted to non-market valuation methods (R. T. Carson, ed. Direct Environmental Valuation Methods, Volumes I and II).The seven essays in Part IV deal with a set of forest economic and policy issues related to global warming and biodiversity conservation. Parks and Hardie (1995) examine the cost-effective subsidies to convert marginal agricultural land to forests for the purpose of carbon sequestration. Hoen and Solberg (1993) analyze the potential and cost-effectiveness of increasing carbon sequestration in existing forests by changing forestry practices. van Kooten, Binkley and Delcourt (1995) examine the effect of carbon taxes and subsidies on the optimal rotation age. The chapter from the Third Assessment Report of IPCC (2001) provides a comprehensive review of the literature on the ecological, environmental, social and economic aspects of carbon sequestration in terrestrial ecosystems. While forests and forest management could play an important role in mitigating climate change, increasing level of atmospheric dioxide and climate change would inevitably affect the productivity of forest ecosystems, thereby could have significant impacts on future timber growth, harvest and inventory as well as carbon storage in forest ecosystems. Joyce et al. (1995) present a framework for analyzing the potential effects of climate change on the forest sector. The remaining two essays in this part examine the costs and benefits of biodiversity preservation, respectively. Montgomery, Brown and Adams (1994) estimate the marginal cost of preserving the northern spotted owl. Simpson, Sedjo and Reid (1996) examine the expected value of the marginal species as an input to pharmaceuticals.The editor points out in the introduction chapter that there are many other important contributions that are not included in this volume, some of these are mentioned, others not. In addition to the few omissions noted earlier, several important economic and policy issues such as uneven-aged stand management, deforestation, international trade, sustainable forestry, forest recreation, wildlife management and so on are not discussed. Moreover, none of the journal essays published since 1997 is selected. That there are many other important contributions does not mean the essays included in this volume are less important, however. While each forest economist may present a different list of the most important papers, most (if not all) of the essays in this volume would appear on anyone's list. I strongly recommend this book for research scientists and graduate students of forest economics as an essential addition to their reference library.

Analysis of individual private forestry in northern Spain according to economic factors related to management

In addition to being motivated by profit, the management decisions taken by non-industrial private forest (NIPF) owners involve other considerations beyond timber, such as non-timber goods and services, as well as factors that affect the level of timber output from the land. Ensuring and improving forest profitability to make NIPF management viable is one of the main challenges faced by this type of landowner. This study empirically explores and assesses management by NIPF owners, through analysing attributes of forest economics (investment in holdings, expenditure on planting and silviculture, public subsidies, along with timber and non-timber incomes). With the aim of predicting outcomes, a multiple regression model was also constructed to investigate and quantify the relationship between socioeconomic and holding factors, and the planting activities carried out by NIPF owners. For this, 103 resident forest landowners in a forest region in northern Spain were interviewed in person, during March 2004, about their commitment to and involvement in land management during the period 1999–2003. The results mainly revealed that attractive forest returns and favourable market conditions for timber production are significant factors for investment in and development of forestry, with personal and family conditions also being important factors in explaining the type of land management carried out. In particular, the multiple linear regression model for forest planting activity correctly explained 84.5% of the variability observed in the study population, indicating that both the investments in and the incomes from forestry play an important role in the activity, as does the size of the holding. The findings may be of interest in promoting public measures related to timber markets and economic incentives for forest management, which will allow landowners to develop economically viable practices, as well as enabling fulfilment of social and environmental demands for sustainable forestry and rural development.     

Forest conservation programs and the landowners who prefer them: Profiling family forest owners in the New York City watershed

Voluntary forest conservation programs offer family forest owners (FFO) financial incentives in exchange for legally-binding land use restrictions and/or management obligations. Protecting family forests in the Catskill Mountains region of New York is an important policy objective, as these watersheds provide clean drinking water to New York City. Multiple methods were used to elicit preferences for forest conservation program attributes and to identify potential barriers to participation. Respondents to a mailed survey were grouped according to the program attribute that most influenced their likely participation into forest conservation programs. Respondents were identified as time-sensitive, payment value-sensitive, rights-sensitive, payment mode-sensitive, or harvest-sensitive. Comparing groups revealed significant differences in age, attitudes towards harvesting trees, income, and importance of timber production. Supplemental qualitative data was collected during three focus groups of survey respondents and analyzed for general themes. Focus group discussions revealed a lack of knowledge about conservation easement programs, reluctance to burden landowners’ children with encumbered land inheritances, concerns for resale values and tax assessment, and a simmering animosity towards New York City’s watershed management efforts. We offer strategies to address these concerns and to design programs that will foster greater participation among FFOs in the region.     

Optimizing joint production of timber and carbon sequestration of afforestation projects

Optimizing harvesting decisions has been a matter of concern in the forestry literature for centuries. However, in some tropical countries, growth models for fast-growing tree species have been developed only recently. Additionally, environmental services of forests gain importance and should be integrated in forest management decisions. We determine the impact of a joint production of timber and carbon sequestration on the optimal rotation of a fast-growing species in north-western Ecuador, comparing different optimization approaches and taking the latest developments of the Kyoto Protocol into account. We find that payments for carbon sequestration have substantial impact on the rotation length: in contrast to an optimum of 15 years when focusing on timber production only, joint production leads to a doubling of the rotation length, which means that timber harvest should be postponed until the end of the carbon project.     

Designating tree crops as forest: Land competition and livelihood effects mediate tree crops impact on natural forest cover in south China

The Chinese government applies the term ‘tree crops’ (jingjilin) to a bundle of tree species with uses other than timber production, defining this category as a component of national forest statistics. Tree crops may displace either farmland or forestland, and can be a promising livelihood option for smallholders. The overall impact of this particular policy on natural forest growth remained unanswered. In the general expansion trend of tree cover in southern China, tree crops could compete for land with natural forests, their cultivation may pose environmental trade-offs with natural forest cover. However, in a context of large labor flows from countryside to cities, tree crops could provide promising opportunities for dealing with on-farm labor shortages and generating income for disadvantaged populations remaining in rural communities, then promoting remaining natural forest quality through alternative livelihoods process. There is a knowledge gap to thoroughly investigate tree crops’ impact on natural forest change both conceptually and empirically, especially a mechanism verification of the alternative livelihood hypothesis. Thus, we construct a framework assessing land use competition and alternative livelihood effects together to assess overall impacts of tree crop cultivation on natural forests. Our dataset combines forest resource inventory data and provincial social-economic factors for a panel analysis of contributions to change in natural forest cover, density, and stock in China’s biodiversity-rich southern provinces. Results show tree crop cover is negatively associated with natural forest extent, but positive associated with change in natural forest density, while the relationship with change in natural forest stock is insignificant. Further tests of mechanisms support the hypothesis that tree crops benefit disadvantaged rural populations, providing an alternative livelihood. Defining tree crops as forest in China obscures important patterns, particularly a trade-off between tree crops and natural forest cover and a possible synergy with natural forest density mediated by alternative livelihood processes. Policy makers should enact specific policies to incentivize natural forest recovery in the southern collective forest zone and reconsider the appropriateness of defining tree crops as forest. Concentration and intensification of tree crop production on suitable lands may have the potential to benefit both forests and impoverished populations.     

Supply potential and annual availability of timber and forest biomass resources for energy considering inter-prefectural trade in Japan

This study estimates the supply potential and annual availability of timber and forest biomass resources under profitable forest management in Japan. It focuses on four prefectures, namely, Fukushima, Ibaraki, Tochigi, and Gunma, and considers the trade between these prefectures. Production forests were extracted as subcompartments where the expected revenues surpassed all costs, from planting to final harvest. To estimate harvesting costs, appropriate harvesting systems were determined according to each prefecture’s topographical features. The log markets and woody biomass power generation plants were assumed to be the destinations for timber and forest biomass resources. Annual availability from the Cut-To-Length (CTL) system, consisting of the use of harvesters and forwarders, accounted for 58 % of the total availability, even though the supply potential from CTL was only 15 %; this is because CTL is the most productive and least expensive harvesting system. Then, the effects of subsidies on availability are examined. Availability under an additional regeneration subsidy meets almost the entire current demand in this region. Furthermore, availability with a thinning subsidy can meet the forecasted future demand in this region, while availability with both thinning and additional regeneration subsidies can meet future demand in all prefectures analyzed in the present study. Thus, subsidies play an important role in the profitability of forestry operations as well as the supply of timber and forest biomass resources in Japan.     

The disappearing chain of responsibility: Legitimacy challenges in the political governance of Finnish Forest and Park Service

This article analyses the consequences of institutional and organisational arrangements for the legitimacy of the governance of Finnish public forests. It focuses on normative legitimacy, which comprises input legitimacy (accountability), throughput legitimacy (power relationships, transparency and inclusiveness) and output legitimacy (problem-solving capacity). These components, and the challenges involved in them, are analysed in relation to the governance of the Finnish Forest and Park Service. It is a hybrid agency which combines business economic tasks with broader societal duties related to public forests. The article draws on the relevant laws, parliamentary reports and comments, policy and planning documents, as well as interviews with MPs, government officials and agency staff. The discrepancy between written regulations and policies on the one hand, and the actual governance practices and rationalities that guide informants’ interpretations and implementation of the regulations on the other, constitutes (in addition to the regulatory vagueness) the key challenge to the system's legitimacy. The Finnish case shows that assigning to Parliament a central formal role in the governance of public forests may serve more as window-dressing than providing genuine legitimacy to the decisions being made, as its actual role is dependent on how – and by whom – such decisions are prepared. The results highlight the importance of inclusiveness and transparency in the governance process; and of concrete, measurable criteria and indicators for each policy goal, against which performance may be assessed on a regular basis.     

Assessing the financial contribution and carbon emission pattern of provisioning ecosystem services in Siwalik forests in Nepal: Valuation from the perspectives of disaggregated users

Provisioning Ecosystem Services (PS) from the forests contribute much to peoples’ livelihoods as well as to the national economy. Previous studies have been constrained by their primary focus on biophysical quantification of PS through modelling and mapping or aggregated monetary valuation, while little attention has been paid to the issues of the distribution of financial benefits among the different forest subgroups. Using market price and substitute good price methods, this paper assesses how local users exploit financial benefits and emit carbon from the use of PS in two dominant community-based forest management systems (community forestry—CF and collaborative forestry—CFM) based on proximity (nearby vs. distant users) and socio-economic class (rich vs. poor users) in the Siwalik region, Nepal. Results indicated that the wealth level of the users plays a key role in the amount of financial benefits generated from the use of PS: (1) users living near forests receive the highest economic benefits compared to those living long distances from the forest area. However the distribution of benefits differs according to management modality and socioeconomic status; (2) CF users, on average, receive higher economic benefits than CFM users; and (3) compared to poor households, rich households receive higher benefits. On average, a rich household adjacent to CF receives USD 1214/year while a poor household living in the same area receives almost half of that (USD 630/year). Similarly, a poor household living far from a forest area generates USD 189/year, slightly higher than that of a rich household in the same area (USD 109/year); and (4) an average CF user emits more carbon (7.4 tCO₂/HH/year) from the consumption of PS than an average CFM user (5 tCO₂/HH/year). Finally, we discuss the reasons behind these differences and draw policy implications for developing and refining constitutions and operational plans of forest user groups.

A review of recent developments and applications of partial equilibrium models of the forest sector

Recent history has seen an increase in the utilization of partial equilibrium based forest sector models to identify potential impacts of various policies or timber market shocks. These models are particularly useful in that they employ economic theory to capture the interaction of supply and demand in a framework where commodity prices are endogenous to the policy or shock simulated. We present recent developments and linkages between models and review applications of these models to forest policy questions over the previous decade. We conclude with a discussion of potential future directions for such research.     

Adapting to the gender order: Voluntary conservation by forest owners in Finland

In this article we explore the hidden gender order of the biodiversity policy and, in particular, the social and societal positions offered to male and female forest owners in voluntary conservation. Two studies were conducted in the region where the National Biodiversity Program for Southern Finland (“METSO”) has been implemented. Study 1 focused on forest owners’ discursive practices that construct different actor positions to female and male forest owners; 27 interviews with forest owners were analyzed. Three discourses – “conservation threatens forestry,” “forestry threatens conservation,” and “good forestry is conservation” – were identified. Forest owners typically described themselves as “loggers” who were explicitly described as masculine. This was paired with the feminine position of “bystander.” The other two positions found, “protectors” and “political agents”, by contrast, were discussed as non-gendered positions. In Study 2 we examined quantitatively how individual forest owners’ nature conservation preferences and willingness to conserve forests is mediated by gender. The responses of 965 owners were analyzed with structural equation modeling. The endorsement of nature conservation preferences was found to increase willingness to conserve forests only among male owners. The results illustrate how individual forest owners adapt their nature conservation preferences to forestry's masculine socio-cultural context.
