Purpose: This article's purpose is to examine the effect of a Classification-Based Forest Management (CFM) program on farmers' income and determine whether its effect varies with the degree of farmers' concurrent occupations. Design/methodology/approach: The authors use representative panel survey data from Longquan to explore the welfare effects of CFM on farmers. The analysis uses differences-in-differences with propensity score matching (PSM-DID) estimation techniques to deal with endogeneity problems when farmers make the decision to participate in CFM. Findings: The results show that CFM has a positive effect on part-time forestry households (where forestry income accounts for between 5 and 50% of total income). In contrast, it has a negative impact on full-time forestry households (forestry income accounts for more than 50%), and no clear effect on nonforestry households whose forestry income is less than 5%. This research also shows that the positive effect of CFM on farmers' total income is mainly due to increase of off-farm income driven by CFM, while the negative effects consist of CFM's reduction of forestry income. Originality/value: The extent of CFM's economic benefits to farmers is uncertain and largely unexplored. This paper analyzes the impact of CFM on income structure to explore the mechanisms explaining its effects on farmers' income. There are still challenges in ensuring the reliability and accuracy of CFM assessment. This paper collected natural experimental data and used the estimation technology of PSM-DID to solve the possible endogeneity problems. [ABSTRACT FROM AUTHOR]

Highlights • Forest resource Metabolism Network model isdeveloped for ecological and economic analysis. • Exploitation index is developed to reveal the weaker sectors in the ecological relations. • A case study of Guangdong province, China isconducted to illustrate the potential benefits. • Scientific Basis are provided to allocate forestresources and stabilize industrial structure. Abstract Integrating forest resources into the socio-economic system correctly and reasonably is of vital importance to tackle the increasingly scarce forest resources. In this paper, forest resource input-output model and forest resource metabolism network model are established to provide new insights into the relationships among the systems, industries and sectors related to forest resources. A promising indicator named exploitation index is developed to reveal the weaker sectors in the ecological relations, which will further help to provide better corrective actions and integrated strategic measures. Guangdong is taken as an example to verify the availability of the model and solve the problem. The results show that the primary manufacturing consumes more direct timber, while advanced manufacturing and the service sector utilize timber indirectly. In addition, Guangdong forest metabolism system shows a negative correlation and the whole network does not achieve the mutualism state, leading to competition relationships between pairwise sectors that should not appear, such as Forestry sector and Papermaking and Paper Products sector. These results provide the corresponding reference for helping the decision makers to allocate forest resources and coordinate ecological and economic development. [ABSTRACT FROM AUTHOR]

FOREST management ,FOREST protection ,ENVIRONMENTAL protection ,SUSTAINABLE development - Abstract
The management and protection of forest resources has become one of the major issues of environmental protection globally. As the largest developing country in the world, China has determined that the construction of an ecological civilization is an important piece of a millennium plan for China's sustainable development. The ecological capital theory, which adheres to the idea of a harmonious coexistence between man and nature, provides an opportunity to open up a new chapter for the construction of ecological civilization. Based on the fact China is a country endowed with unique resources, this paper aims to provide a theoretical reference on how to maximize the value of forest ecological resources and promote the sustainable development of global forest resources. To gain clear insights, this paper uses the theory of ecological capital to discuss how to demarcate the concept of the capitalization of forest ecological resources. The internal motivation of the capitalization of forest ecological resources was analysed from two perspectives: how to keep the balance between ecological protection and resource development, and how people have changed the way of using forest resources. This paper has expounded how forest ecological resources are transformed to forest ecological assets and then forest ecological capital, indicating the realization path of the capitalization of forest ecological resources, that is, a direct utilisation of forest resources and indirect new ways of forestry management. It aims to provide theoretical references for maximizing the value of forest ecological resources and achieving the sustainable development of global forest resources. [ABSTRACT FROM AUTHOR]

As skilled talent is the core element in optimizing the industrial structure, clarifying the factors that influence the lack of skilled talent in the agricultural industry is essential. The lack of skilled talent in the agricultural industry is a complex problem. The author based this study on the push–pull theory and used the fuzzy-set qualitative comparative analysis (FSQCA) research method to explore the "joint effect" of the factors that affect the lack of skilled talents in the agricultural industry in 14 cities of Hunan Province. This paper found that indicators such as the rural industry status, rural medical level, agricultural and forestry financial investment, urbanization construction, regional economic development level, and local government officials were all presented under sufficient conditions. These influencing factors have a "combined effect" on the agricultural industry's lack of skilled talent. The rural industry status indicator was the core condition, appearing in all the configurations. This article's main marginal contribution is that it defined three conditional configurations for the lack of "present" agricultural skilled talents, and dependent configurations are consistent. Among the three conditional configurations, the "rural industry + economic construction and financial investment" configuration is the most powerful way to retain skilled agricultural talents. In addition, the causal relationship between the lack of "present" agricultural industry skilled talents and the lack of "absent" agricultural industry skilled talents are asymmetric. The primary task is to develop rural industries to solve the problem of the shortage of skilled talent in the agricultural industry. Additionally, then implement the 'industry+' combination policy. So the government must create related policies in the following areas: the supply of essential public services in rural areas, the economic construction of prefectures, the development of county urbanization, and the financial investment in agriculture, forestry, and water conservancy.

Forests and the dynamic changes play decisive roles in soil erosion prevention, biodiversity conservation and climate warming mitigation, and are crucial for China to achieve carbon neutrality because of the ability for carbon uptake. China's forests experienced a substantial change over the past century, primarily since the forest conservation and restoration programs were implemented. In this paper, the progress of China's forest change and the similarities and differences of the spatio-temporal patterns from multi-dimension coupling with ground surveys and satellite observations were reviewed comprehensively, and the drivers of forest change were discussed. Our review reported that: 1) China's forests experienced an extensive forest gain/restoration in vegetation greenness, forest cover, and aboveground biomass since the 1970s. 2) Changes in various forest parameters suggested distinctive spatiotemporal patterns in China. Consistent hotspots of forest gain clustered in the Loess Plateau and the southwestern China from most studies, while controversial conclusions about forest loss/degradation were found in the spatial distribution. 3) The geographic discrepancy of forest changes may be related to climate change, human activities, and forest disturbances. Variations in forest dynamics are prerequisites to exploring the effects of natural conditions and forestry policies on forest cover, and strengthening understanding of the carbon cycle. These findings can provide valuable insights for various ecological services in further studies and a scientific basis for forest management and policy-making in China. [ABSTRACT FROM AUTHOR]

Over the past twenty years, historians and political scientists have explored extensively how structures, institutions, coalitions and recently also information have affected China's environmental governance. Much less is known about how time consciousness has informed political action. This paper draws on theories of historical times to analyse key party and government documents on forest management published between 1949 and 2021. Two research questions are tackled. How has time been negotiated in programmatic ideas of forest development? How has time-consciousness connected to forest policymaking in different historical periods? The findings demonstrate that environmental policies in China were not only informed by ideological struggles over programmatic ideas and how (i.e., by which governance mode and instruments) to best manage natural resources. The policies were also affected by ideological struggles over temporalities and time horizons. The findings draw attention to an under-researched factor in political processes in China and across societies and political systems. [ABSTRACT FROM AUTHOR]

Recent research shows that China is experiencing significant greening, with afforestation initiatives being the main cause. Quantitative calculation of vegetation change influencing factors and evaluation of the contribution of afforestation to vegetation greening in China are critical to coping with climate change and improving the implementation and efficacy of forestry projects. We investigated the temporal and spatial dynamics of the Normalized Difference Vegetation Index (NDVI) from 1982 to 2020, and quantified the contribution of afforestation initiatives, a typical human activity, to the dynamic changes of vegetation. The results showed that NDVI in China has primarily increased in the last 39 years. 57% of the pixels increased, 27% were stable and unchanged, and 16% decreased. Climate change was responsible for 72.34% of vegetation restoration, while human activities were responsible for 27.36% of vegetation restoration, according to residual analysis. In the future, only 14% of the regions showed continuous growth of the NDVI, while the remaining regions showed obvious antipersistence (59% will go from increasing to decreasing, and 22% will go from decreasing to increasing). The contribution of climate factors to vegetation change will decrease in the future, and human activities will become more complex. Except for Huaihe River and Taihu Lake (SPHRTL), other forestry projects showed an increasing trend of NDVI after the implementation of ecological engineering. However, due to differences in climate conditions and ecological engineering implementation, there are differences in the benefits of forestry projects. Some forestry project areas still have obvious vegetation degradation, and appropriate forestry management is necessary. This work provides a quantitative analysis of vegetation change and its driving factors in China, which will help to cope with future climate change and provide a reference for the implementation and management of ecological projects.

Carbon emissions pose a significant challenge to sustainable development, particularly for China, which is the world's largest emerging economy and is under pressure to achieve carbon neutrality and reduce emissions amid escalating human activities. The variation in economic development levels and carbon sequestration capacities among its provinces poses a significant hurdle. However, previous research has not adequately examined this dual discrepancy from the perspective of spatial heterogeneity, resulting in a lack of differentiated management of forest carbon sinks across diverse regions. Therefore, to mitigate this discrepancy, this study presents an assessment methodology that analyzes over 100 types of natural and plantation forests using forest age and biomass expansion factors. This study presents a model that can significantly support the efforts of both China and the whole world to achieve carbon neutrality through the improved management of forest carbon sinks. This approach facilitates the assessment of carbon offsets required to meet reduction targets, the development of a provincial framework for carbon intensity and sequestration, and the exploration of their potential for trading markets. Analysis is conducted using MATLAB. Key achievements of this study include the following: (1) The collection of a comprehensive carbon stock dataset for 50 natural and 57 plantation forest types in 31 provinces from 2009 to 2018, highlighting the significant role of new forests in carbon sequestration. (2) The development of a provincial carbon status scoring system that categorizes provinces as carbon-negative, carbon-balancing, or carbon-positive based on local forest sink data and carbon credit demand. (3) The formulation of the carbon intensity–carbon sink assessment (CISA) model, which suggests that provinces with middle- to upper-middle-level economies may have a prolonged need for carbon sink credits during their peak carbon phase. Furthermore, the results show that carbon trading may benefit Guangxi and Yunnan, but may also bring opportunities and risks to Hunan and Hubei. To address regional imbalances, this study advocates tailored policies: carbon-negative and carbon-balancing provinces should enhance carbon sink management, while carbon-positive provinces must focus on energy structure transformation to achieve sustainable development goals.

Carbon leakage can be a problem when seeking to reduce carbon emissions through forest policy. International market leakage is mainly caused by supply and demand imbalances in the timber market. This paper selects China, which is implementing forestry policy changes, as the research object. We begin by offering a brief analysis of China's forestry policy changes, such as the logging quota and Six Key Forestry Programs to determine whether those policies affect timber supply. Second, through the use of three shock variables, carbon leakage is simulated under different scenarios by the Global Trade Analysis Project (GTAP) model. The results reveal that the magnitude of leakage caused by implementing China's forestry policies is between 79.7% and 88.8% with carbon leakage mainly displaced to Russia, Southeast Asia, and the EU. Two effective scenarios for reducing market leakage are presented: forest tenure reform and fast growing forest projects to improve domestic timber production, and raising tariffs on timber imports to reduce imports.

The Chinese government has recently been attaching increasing importance to the application of effective legal tools to tackle land degradation (LD) issues. Based on the concept of sustainable development, China began developing and reaping the benefits of environmental and natural resources legislation including LD control regulations in the 1990s. In the past three years, some central-western provinces in China have been implementing a “ People's Republic of China/Global Environment Facility (PRC/GEF ) Partnership on LD Control of Dryland Ecosystems”, which is based on an integrated ecosystem management (IEM) approach. IEM is designed to achieve a balanced, scientific and participatory approach to natural resources management, which creates the potential to improve the quality of Chinese environmental law and policy procedures. The paper studies the existing Chinese national laws and regulations pertinent to LD control within 9 areas covering land, desertification, soil erosion, grassland, forest, water, agriculture, wild animals and plants, and environment protection in detail, against IEM principles and basic legal elements. The main objective is to identify problems and provide feasible solutions and recommendations for the improvement of the existing laws and regulations. The authors conclude that the development of an improved national legislative framework is essential if LD control is to be successfully achieved. The paper is partly based on Component 1 — Improving Policies, Laws and Regulations for Land Degradation Control under PRC/GEF Partnership on Land Degradation in Dryland Ecosystems (TA 4357).

As one of the most important renewable and sustainable energy sources, the forest biomass energy resource has always been the focus of attention of scholars and policy makers. However, its potential is still uncertain in China, especially with respect to its spatial distribution. In this paper, the quantity and distribution of Chinese forest biomass energy resources are explored based mainly on forestry statistics data rather than forest resource inventory data used by most previous studies. The results show that the forest biomass energy resource in China was 169 million tons in 2010, of which wood felling and bucking residue (WFBR),wood processing residue (WPR), bamboo processing residue, fuel wood and firewood used by farmers accounted for 38%, 37%, 6%, 4% and 15%, respectively. The highest resource was located in East China, accounting for nearly 39.0% of the national amount, followed by the Southwest and South China regions, which accounted for 17.4% and 16.3%, respectively. At the provincial scale, Shandong has the highest distribution, accounting for 11.9% of total resources, followed by Guangxi and Fujian accounting for 10.3% and 10.2%, respectively. The actual wood-processing residue (AWPR) estimated from the actual production of different wood products (considering the wood transferred between regions) showed apparent differences from the local wood processing residue (LWPR), which assumes that no wood has been transferredbetween regions. Due to the large contribution of WPR to total forestry bioenergy resources, the estimation of AWPR will provide a more accurate evaluation of the total amount and the spatial distribution of forest biomass energy resources in China.

This paper aims to demonstrate the advantages of adopting an ethnographic, actor interface approach to understanding the ongoing dynamics of rural development and policy intervention processes. It does so through the discussion of an EU-funded project orientated to introducing village-level forest-management practices in north-west China. The case highlights the ongoing everyday struggles over livelihoods and resources and focuses on the negotiations that take place between the various social actors involved. The case analysis is preceded by a broadsweep overview of the rise of new ruralities and a discussion of the key elements of an actor interface analysis. The article concludes with a call for more cross-country and cross-regional studies of this kind. [ABSTRACT FROM AUTHOR]

The relationship between forests and streamflows has long been an important research interest in China. The purpose of this paper is to summarize progress and lessons learned from the forest-streamflow studies over the past four decades in China. To better measure the research gaps between China and other parts of the world, a brief global review on the findings from paired watershed studies over the past 100 years was also provided. In China, forest management shifted in the later 1990s from timber harvesting to forest restoration. Forest-streamflow research was accordingly changed from assessing harvesting impacts to evaluating both harvesting and forestation effects. Over the past four decades, Chinese forest hydrology research has grown substantially. Significant progress has been made on measuring individual processes, but little solid, long-term data were available to assess the relationship between forest changes and streamflows because of an absence of standard paired watersheds. In addition, misuse of statistical analyses was often found in the literature. A unique opportunity exists in China to study the forestation effects on streamflow as several large-scale forestation programs are being implemented. Such an opportunity should include a robust paired watershed design under an integrated watershed ecosystem framework to avoid repeating the lessons already learned. Recommendations on future forest-streamflow research directions in China are provided. [ABSTRACT FROM AUTHOR]

Bamboo forests, due to their special characteristics and ecological functions, play an important role in sustainable forest management and rural development in China. Over the past two decades, China has successfully established millions of hectares of bamboo forest, which has restored fragile ecosystems, provided benefits to local communities, alleviated rural poverty and eased timber shortages. However, there is potential for further improvements to the bamboo forest estate. This paper analyses the current state of bamboo forest resources and management, and the roles of the bamboo forest industry in social development, economic growth and ecosystem protection in China. We examine the main issues related to governance systems, local economic development and traditional management practices. Finally, we suggest some directions for future development.

On the island of Hainan, China, the provincial government has recently committed itself to sustainable development, which requires the integration of social, environmental, and economic factors in decision making. However, while Hainan’s recent Eco-province designation establishes environmental and economic factors as the basis of policy development, it overlooks the equally important social component of sustainability, in which social needs and values are key considerations. This paper presents the results of a study on Hainan in 2002, with government officials, forestry workers, and the Li, an indigenous minority group, and places the province’s situation within the context of both the larger changes underway in China, and the theory and practice of sustainable forestry. The research results show that the government of Hainan has not yet been able to manage both social welfare and environmental and economic issues, demonstrating the difficulty of implementing sustainable forestry and of balancing short- with long-term goals. The inclusion of Li communities in forestry-related decision making could reduce tensions between local communities and forestry management and also improve the sustainability of the government’s forestry practices.

Forest age is one of the most important ecosystem characters for accurately estimating the magnitude and potential of carbon sink in forest ecosystems. During the past 40 years, national ecological restoration projects have led to the near doubling of the forest cover area in China, which has also substantially affected the dynamics of forest age. Therefore, there is an urgent need to generate long‐term forest age maps for China. This study reconstructed China forest age datasets (CFAD) from 1980 to 2015 at five year intervals at a 1 km spatial resolution by merging a satellite‐based forest age map in 2010 and forest cover dynamic maps from 1980 to 2015. The random forest method was used to reconstruct the forest age where forest age could not be inferred from the forest age base map in 2010 directly. CFAD showed a good agreement with the province‐level mean forest age derived from the several national forest inventories (R2 ranged from 0.66 to 0.86). In general, the younger forests are mainly distributed in southern and eastern China. The older forests are mainly distributed in the mountain areas of northeast, northwest and southwest China. The average age of China's forests increased from 18.2 to 44.0 years old from 1980 to 2015. Based on the current forest age and future afforestation planning, the average forest age in China is predicted to reach 71.6 years old in 2060. The CFAD provides an alternative data set to obtain improved estimates of local and national forest carbon sinks in China. Plain Language Summary: Planting trees and protecting trees from timber harvest will help China to achieve the goal of carbon neutrality by 2060. The large scale national ecological restoration projects from the 1980s have substantially changed the structure of forest age in China. However, accurate long‐term forest age datasets for China are still unavailable. Therefore, we produced a new forest age data set for China from 1980 to 2015 by combining a reliable satellite‐based forest age base map in 2010 and high quality forest cover dynamic maps from 1980 to 2015. Using the latest four national forest inventories data set as independent observations, we found the new forest age map data set had a high validation accuracy. High quality and long‐term forest age maps are essential to better estimate the carbon dioxide absorption potential of trees and design of optimal forest management policies. Key Points: We reconstructed long‐term China forest age datasets by combining forest inventories, satellite‐based forest age and forest cover datasetsThe 1 km resolution forest age maps showed a good agreement with the provincial mean forest age derived from the national forest inventoryThe spatial and temporal patterns of changes in China's forest age are illustrated [ABSTRACT FROM AUTHOR]

Considering the globalization of forest land use and the influence of China's socio-economic process on forest resources, this paper provides a comprehensive overview of China's forest land use change in the globalized world economy during 2000–2011, by means of embodiment accounting based on EXIOBASE3 database. External demand, primarily from USA, EU, Japan and rest of Asia-Pacific, accounts for 20−45% of China's direct forest land use, meanwhile, increasing forest land use (50−60%) is displaced abroad, mainly to Russia (20−30%), America, Africa and rest of Asia-Pacific. Overall, China is a net importer of virtual forest land use due to large imports through forest products (e.g., wood, paper and pulp), while highly-processed non-forest products also contribute a dominant and increasing share in total exports. Consequently, in the trade with USA, Japan and many European countries, China is the net exporter of virtual forest land use, though it is the net importer of forest products as revealed by conventional monetary trade accounting, highlighting the necessity of the inclusive embodiment accounting to trace land use to actual final products. Regarding final consumption, virtual forest land use of rural households only reaches 65–75% that of urban households, due to large disparities in the consumption of non-forest products. Per capita virtual forest land use of the rural and urban poorest groups are only 1/5 and 1/6 of the nation's richest group, respectively. Therefore, transnational cooperation is required to promote sustainable forest management worldwide. China should also prepare for growing demand for forest land and reduce associated environmental inequality in the process of urbanization and poverty alleviation. ga1 • China is a net importer of virtual forest land use. • Growing forest land use is displaced abroad (50–60%), mainly to Russia. • External demand, mainly from US & EU, makes up 20–45% of domestic forest land use. • Urban-rural forest land use disparity exists, shaped by non-forest products. • China's urbanization and poverty alleviation are likely to push up forest land use.

High conservation value forest (HCVF) theory has aroused wide concerns among related forestry sectors in China, but the zoning and identification of HCVF only have been implemented in a few forest management units (FMUs). As there is no quantitative indicator for identifying and zoning HCVF in China, most FMUs are unable to have an exact zoning result This paper introduced the concepts of HCVF and ecological forest, and compared their similarities and differences in terms of identification criteria, zoning methods and application scope. With four Chinese FMUs as case studies, some suggestions were proposed for establishing a zoning scheme of HCVF so as to promote the development of HCVF in China. [ABSTRACT FROM AUTHOR]

The world's forests have historically been managed as systems in which environmental health is compromised for the sake of economic efficiency and growth. China's forest policy framework has generally followed this paradigm as large-scale deforestation over the 20th century led to landscapes that, while economically productive, were made vulnerable to natural disturbances. However, in recent decades China has experienced substantial forest reforms that aim to protect important forested lands while simultaneously increasing timber outputs from plantations. Multiple green growth oriented programs have been in place to attain these objectives with the anticipation that rural poverty can be alleviated and the vulnerability towards natural disasters can be avoided. A growing body of research demonstrates the success of these reforms for improving the lives of landowners while also increasing the country's forest cover. However, these reforms have brought upon substantial change to the relationship within and between social, economic and ecological properties of the nation's forest system, and consequentially its ability to respond and adapt to change in the future. The objective of this paper is to describe the relationship between forest policy and environmental change in China during the last century using a complex adaptive systems framework. This approach demonstrates the coupled nature of policies and forest dynamics that need to be considered in future policy development. China's green growth directed policies and practices must embrace a perspective of constant change and the inevitability of perturbations and disturbances. In this way, China can begin to consider how to build resilience into its policies and management strategies so that the overall system maintains a level of flexibility that allows it to adapt to unforeseen economic and ecological change.

Local ecological knowledge informs how natural resource patches are identified and valued across a landscape by communities that rely on them. However, local knowledge is not always considered in quantitative models evaluating resource access and quality. Based on ethnographic fieldwork in southwest China, I integrate ecological, economic, and cultural factors to model non-timber forest product distribution and resource access in a community-based forest governance system. Observations over four mushroom harvesting seasons suggest that the distribution of harvesters relative to available resources follows the expected distribution under an ideal free distribution (IFD). An emergent ideal free distribution is significant as it may offer evidence of sustainable and equitable resource management. Moreover, this case offers an extension of the IFD by basing model parameters on locally-determined forest values and knowledge rather than predominantly environmental variables. Finally, results reaffirm that local forest management systems with adaptive property rights and redistributive norms offer multiple benefits for addressing resource governance challenges.

• We propose a new forest prediction model and use actual deforestation data for optimization and verification. • Use the XGBoost method to reconstruct deforestation intensity data. • Deforestation hotspots in China are mainly concentrated in the southern and southeastern regions. • Our model provides certain reference information for forest disaster prevention and forest management. Forests are important for the global carbon cycle, hydrothermal balance, and climate change. Human activities can exert a significant impact on forest ecosystems, thereby having the potential to alter their physical and chemical properties and thus affecting carbon, water, and heat budgets, and climate change. The historical reconstruction of the disturbance of global forests can help us understand the processes and patterns of human activities and global change. In this paper, we construct a deforestation prediction model using a Spearman correlation coefficient and implement the XGBoost method, using Python 3.6, for the reconstruction of deforestation intensity data from 2000 to 2019. Secondly, the selection of the driver indicators is done by using extreme difference regularization to unify the magnitude, and the potential deforestation area risk index is calculated in the form of equal weights. Finally, the actual deforestation data were used for optimization and validation. The model shows that the deforestation hotspots are mainly concentrated in the southern and southeastern regions of China and that there are large differences in deforestation in different provinces. In the future, the fine spatial and temporal patterns of deforestation in China during the historical period can be quantitatively reconstructed, which can provide some reference information for forest disaster prevention and forest management in China.

Abstract: This paper develops three scenarios for the management of an existing, low productivity, collective forest plot in Southwest China: continuation of the status quo, transition to sustainable forest management (SFM), and conversion to a short rotation species for producing biomass for electricity generation. We examine how economic incentives vary across the three scenarios and how payments for CO2 sequestration and offsets affect incentives. We find that SFM is risky for forest managers and is highly sensitive to revenues from initial thinning; that carbon revenues can lower some of the risks and improve the economics of SFM; but that carbon revenues are effective in incentivizing management changes only if yield response to thinning is moderately high. Energy production from stem wood is too low value to compete with timber, even with revenues from CO2 offsets. However, conversion of existing forests into short rotation species for timber rather than energy is more profitable than any scenario considered here, highlighting the need for regulatory innovations to balance incentives for timber production with conservation goals. The results underscore the importance of improved public sector regulatory, planning, extension, and analysis capacity, as an enabling force for effective climate policies in China’s forestry sector.

Abstract: Competing uses of land mean that regulations aimed at environmental conservation often conflict with the land-use rights of rural households. Several reports suggest that this has occurred with the introduction of the Natural Forest Protection Programme (NFPP) in China, one of the world''s largest logging ban programmes. This paper investigates whether households should be compensated for infringements on property rights, drawing on institutional economics literature on regulation. We distinguish between cases where regulation solves local collective action problems and increases the welfare of those affected, and those where regulation involves a redistribution of rights from one group to another. We apply this to the NFPP by estimating the net welfare impacts, using household level stated preference data with econometric techniques that explicitly account for zero and negative values of the dependent variable. We find that the ban on logging does not affect the net welfare of the affected forest communities. This indicates that the losses resulting from the restrictions on property rights are offset by the benefits from restrictions on other local households. We also find evidence that a partial reduction in logging would be welfare increasing, indicating that the NFPP is to some extent addressing local collective action problems in forest areas. Broader implications for the question of compensating for infringement of property rights as the result of regulatory interventions in contexts of institutional imperfections are also drawn.

Using the latest forest inventory, this article provides a detailed analysis of China's changing forest sector by focusing on new forest trends, forest policy changes, and challenges to achieving a sustainable forest management. The authors analyze the dynamics of forest resources and provide an impact assessment of forest policies on China's forestry development during the past decades. Moreover, the analysis of the forest market highlights substantial disequilibria marked by a limited domestic supply potential and a growing demand for forest products satisfied by increasing imports. Internal and external solutions are explored, and their implications for China and supplying countries are assessed. [ABSTRACT FROM AUTHOR]

Summary: Via computable general equilibrium modeling we find that as a result of economic growth, Yuan appreciation, and logging restrictions in China, China’s imports and exports of forest products would dramatically increase, and China’s imports would have displacement effects as timber-exporting countries would increase their exports to China while reducing their shipments to other countries. Such displacement effects would make pressure on forests in supplying countries less than they otherwise might be. Global economic growth is a dominant driving force for China’s imports. Russia, Southeast Asia, and Africa would remain major foreign suppliers of logs to China, while supply sources for Chinese imported lumber and paper products would be relatively diverse.

This research investigates regional variations of forestland changes in China's coastal areas and potential drivers during 1996–2015. GIS-based spatial analyses including Local Moran's I and GWR are employed in this study. The overall forestland has increased before 2009 but declined since then. The forestland changes have varied over both space and time, which can be seen as a response to the fast urbanization and government policies in recent years. Factors such as arable-land changes and forestland at the beginning of a period were found significantly associated with the forestland changes. Coastal forests play a critical role in the defence of natural disasters like typhoons and tsunamis. The deforestation and forest degradation due to rapid urbanization has presented great challenges (e.g. debris flows and floods) to China's coastal areas. Using a unique national land-use survey dataset and geographical information system (GIS)-based spatial analytics, including local Moran's I and geographically weighted regression (GWR), this paper investigates the regional variations and associated driving forces of forestland changes in China's coastal areas across three periods: 1996−2000, 2000–2008 and 2009–2015. The results suggest that the forestland has generally increased until 2008 and has decreased since 2009. Particularly, some counties in the south coast have higher degree of forestland loss during 1996–2008 and the growth of forestland after 2009 was only found in a few counties in the north and east coast. Also, the results indicate that the initial proportion of forestland in each period and the changes of arable-land have significant positive associations with the forestland changes across all the three periods, where the former mainly affects the northern coast while the latter has a primary influence in the southern coast. The findings suggest that government policies for increasing forestland such as the "Grain for Green" project were highly effective in China's coastal areas before 2008 but have shown less impact ever since. This research provides insights into the dynamics of forestland in China's coastal areas and can assist with future decision-making regarding forest resources protection and management.

Aim: China's Grain for Green Program (GFGP) is the largest reforestation programme in the world and has been operating since 1999. The GFGP has promoted the establishment of tree plantations over the restoration of diverse native forests. In a previous study, we showed that native forests support a higher species richness and abundance of birds and bees than do GFGP plantations and that mixed‐species GFGP plantations support a higher level of bird (but not bee) diversity than do any individual GFGP monocultures (although still below that of native forests). Here, we use metabarcoding of arthropod diversity to test the generality of these results. Location: Sichuan, China. Methods: We sampled arthropod communities using pan traps in the land cover types concerned under the GFGP. These land use types include croplands (the land cover being reforested under the GFGP), native forests (the reference ecosystem as the benchmark for the GFGP's biodiversity effects) and the dominant GFGP reforestation outcomes: monoculture and mixed‐species plantations. We used COI‐amplicon sequencing ("metabarcoding") of the arthropod samples to quantify and assess the arthropod community profiles associated with each land cover type. Results: Native forests support the highest overall levels of arthropod species diversity, followed by mixed‐species plantations, followed by bamboo and other monocultures. Also, the arthropod community in native forests shares more species with mixed‐species plantations than it does with any of the monocultures. Together, these results broadly corroborate our previous conclusions on birds and bees but show a higher arthropod biodiversity value of mixed‐species plantations than previously indicated by bees alone. Main conclusion: In our previous study, we recommended that GFGP should prioritize the conservation and restoration of native forests. Also, where plantations are to be used, we recommended that the GFGP should promote mixed‐species arrangements over monocultures. Both these recommendations should result in more effective protection of terrestrial biodiversity, which is an important objective of China's land‐sustainability spending. The results of this study strengthen these recommendations because our policy prescriptions are now also based on a dataset that includes over 500 species‐resolution taxa, ranging across the Arthropoda.

Financial returns of forest plantations are an important concern around the world. In this research, we focused on South China's timber investments, collected data from the Pingxiang, Guangxi Province, China, which is the demonstration zone of Fast-growing and High-yielding Timber Plantation Base Construction Program and National Timber Strategic Storage and Production Bases Construction Program, and used capital budgeting analysis method and sensitivity analysis to compare different scenarios of planted forest management. The results showed that excluding land costs, (1) the financial returns of Eucalyptus forest managed by small business were excellent, having an IRR of 28% per year and a LEV of $7555 per ha, but it had a high risk with fluctuations of cost, timber price and timber yield; (2) the results for the Experimental Center of Tropical Forests indicate that the Eucalyptus forest and Castanopsis hystrix forest returns were greater than those for Cunninghamia lanceolata forest and Pinus massoniana forest, with having IRRs of 24%, 21%, 13% and 10% per year respectively. The mixed planted forest of Castanopsis hystrix × Eucalyptus and Castanopsis hystrix × Pinus massoniana had the features of high profits and low risks; (3) the forest farmers had lower levels of returns for Eucalyptus forest management in South China, but were still in the middle rank of global comparisons. This study gave a view of China's timber investment and provided more options of improving the economic returns of planted forest management to both small businesses and forest farmers in South China.

This case study analyzed the performance of a start-up cable yarding crew in southern China through operational monitoring by consecutive time studies, long-term log book recordings and efficiency evaluation by stochastic frontier analysis (SFA). The crew, which used a KOLLER K30³ H mobile tower yarder, was monitored for two years. During this period, detailed data recordings of 687 yarding cycles of 12 yarding corridors as well as log book recordings of an additional 1122 scheduled system hours (SSH, including all delays) were generated. Mean extraction productivity of the system ranged between 5.23 and 6.40 m³ per productive system hour (PSH0, excluding all delays), mostly depending on slope yarding distance and lateral distance. Corresponding gross-productivity ranged from 1.91 to 2.24m³/SSH, with an overall mean machine utilization rate of 31%. Unproductive yarding times and delays associated with the relative low utilization rate were mainly caused by lengthy rigging processes, as well as organizational deficiencies and not yet fully developed skill sets of the operating crew. The latter was reflected in a mean efficiency effect frontier value of 0.62 based on evaluation of data sets of individual yarding cycles recorded during detailed assessments, suggesting a mean improvement potential of 38% based on the SFA, translating in a potentially achievable gross-productivity of 2.64 to 3.09 m³/SSH. We conclude that current local operating conditions including insufficient planning, implementation and logistics and in particular, frequent discontinuations of system operations of up to three months all resulting in generally low operation hours per shift and per year, inhibit efficient operations and rapid skill development. These circumstances also inhibit an economic utilization of the equipment. Nevertheless, from a technical perspective, yarding systems have a promising potential in southern China.

Identifying the main sources of conflict and understanding the relationships between protected areas and local communities are critical to conflict resolution related to protected area management. We surveyed and assessed the perceptions of local people related to forest values of the Bulong Nature Reserve (BNR), Yunnan, China, and their attitudes toward forest management of the recently-established nature reserve. Factors influencing the differences in perceptions and attitudes were investigated. Our results indicated local residents preferred the economic value of forests, and they perceived more forest values after reserve establishment than before, especially for ecological services. Interviewees believed the value of the forests have increased, and predicted that the forest will have increased importance to their livelihoods and health in the future. Nonetheless, the majority of interviewees were dissatisfied with current reserve management. Variation in these perceptions and attitudes were related to several social variables: age, gender, education, and distance from the reserve. Embedding the findings of the present study, specifically the perceptions and attitudes of local people, into management guidelines for mitigation of potential conflicts is proposed and should help managers to achieve biodiversity-related goals. This study offers new insights related to the identification of the underlying sources of conflict in forest management and provides a better understanding of the relationship between local people and protected areas. The study also contributes to the literature on forest values of indigenous populations by examining those of remote, rural populations in China. [ABSTRACT FROM AUTHOR]

Recognition of the importance of forests for local livelihoods, biodiversity and the climate system has spurred a growing interest in understanding the factors that drive forest-cover change. Forest transitions, the change from net deforestation to net reforestation, may follow different pathways depending on a complex interplay of driving forces. However, most studies on forest transitions focus on the national level rather than the local level. Here, case studies from 10 villages in Yunnan, China, are used to clarify the complex interactions among various pathways of forest transitions, derive insights on the underlying drivers that shaped the forest transitions, and determine the importance of changes in drivers over time. The results demonstrate that China's recent forest transition was caused by a range of interrelated pathways that were mediated by local circumstances. The degradation of forest ecosystem services caused by rampant deforestation and forest degradation created a scarcity of forest products and triggered state-initiated afforestation efforts, particularly in the 1990s, which continue to be important. More recently, economic development concomitant with smallholder intensification spurred reforestation, while the importance of state forest policy declined. The complexity of local land-use changes demonstrates the difficulty of identifying distinct transition pathways and calls for a more diverse approach that recognizes the interdependence of local processes.

The effective prevention and control of forest disasters is important for forest resources and the well-being of those living in forested areas. This study evaluates the impact of a policy that employs a rural impoverished population as ecological forest rangers (EFRs) for the incidence of forest disasters. We estimate a generalized difference in differences (DID) model using nationwide provincial-level forest disaster data combined with regional data in all policy pilot areas. There are three primary findings. (1) The implementation of the EFR policy failed to effectively reduce the incidence of forest fires, forest pests, forest diseases, forest rodents and other forest disasters, which shows that the EFR policy has not achieved the goal of "forest protection". (2) The effect of the EFR policy on forest disaster control is not significantly different among provinces with different forest resource endowments and different levels of social and economic development. This shows that there is no significant difference in the implementation of EFR policies between different forest resource endowments and different socioeconomic development areas. (3) The EFR policy failed to achieve the effective coordination of the dual goals of "poverty reduction" and "ecological protection"; this is the main reason for the failure to reduce the incidence of forest disasters while reducing poverty. The pressure of this policy neglected the "forest management and protection" function of the policy and the corresponding assessment requirements. At the same time, the central government also neglected the assessment of the prevention and control of "forest disasters" by local governments when implementing this policy. Ultimately, the opportunism of local governments and ecological rangers was strengthened. Therefore, the goals of environmental service payment items and the corresponding evaluation index settings need to be matched to truly achieve the established goals. [ABSTRACT FROM AUTHOR]

As part of its efforts to curb greenhouse gas emissions, China has committed to expanding the country's forest area by 40 million hectares and stocking volume by 1.3 billion m³ from 2006 to 2020. Our analysis suggests that it is very likely that China will realize its goal of forest area expansion; but the target of volume increase represents only a modest gain, which may absorb about 2% of its cumulative carbon emissions. However, China's forests can be a much more significant carbon sequester and ecosystem services provider if its forest growth rate and stocking level are boosted by improving forest quality and productivity. To that end, however, the silvicultural practices and governance structure must be transformed. [ABSTRACT FROM AUTHOR]

The increase of coverage of forest/vegetation is imperative to improve the environment in dry-land areas of China, especially for protecting soil against serious erosion and sandstorms. However, inherent severe water shortages, drought stresses, and increasing water use competition greatly restrict the reforestation. Notably, the water-yield reduction after afforestation generates intense debate about the correct approach to afforestation and forest management in dry-land areas. However, most studies on water-yield reduction of forests have been at catchment scales, and there are few studies of the response of total evapotranspiration (ET) and its partitioning to vegetation structure change. This motivates us to learn the linkage between hydrological processes and vegetation structure in slope ecosystems. Therefore, an ecohydrological study was carried out by measuring the individual items of water balance on sloping plots covered by different vegetation types in the semiarid Liupan Mountains of northwest China. The ratio of precipitation consumed as ET was about 60% for grassland, 93% for shrubs, and >95% for forestland. Thus, the water yield was very low, site-specific, and sensitive to vegetation change. Conversion of grassland to forest decreased the annual water yield from slope by 50-100 mm. In certain periods, the plantations at lower slopes even consumed the runon from upper slopes. Reducing the density of forests and shrubs by thinning was not an efficient approach to minimize water use. Leaf area index was a better indicator than plant density to relate ET to vegetation structure and to evaluate the soil water carrying capacity for vegetation (i.e., the maximum amount of vegetation that can be supported by the available soil water for an extended time). Selecting proper vegetation types and plant species, based on site soil water condition, may be more effective than the forest density regulation to minimize water-yield reduction by vegetation coverage increase and notably by reforestation. Finally, the focuses in future research to improve the forest-water relations in dry-land areas are recommended as follows: vegetation growth dynamics driven by environment especially water conditions, coupling of ecological and hydrological processes, further development of distributed ecohydrological models, quantitative relation of eco-water quota of ecosystems with vegetation structures, multi-scaled evaluation of soil water carrying capacity for vegetation, and the development of widely applicable decision support tools.
