Urban forest in China: Development patterns,influencing factors and research prospects

Urban forest is a very important part of urban ecosystems and provides significant ecosystem services. It benefits urban communities environmentally, aesthetically, recreationally and economically. This article reviews the development status, development patterns and influencing factors of urban forest in China. There are four typical development patterns of urban forest in China: the forest city, garden city, ecological economics and forest greenbelt. Social, climatic, economic and other factors influence urban forest development in China. Social factors include government behaviour, laws and regulations, science and technology, education and culture, public awareness and participation, ecological planning and management. Climatic factors include rainfall, temperature and sunlight. Economic factors include urban economic level and funding for urban forest. In future, government, NGOs and the private sector should be considered more in the planning and management of urban forest. The social, climatic and economic factors should be taken into account when improving urban forest management. Research on urban forest from the academic and the management viewpoint should be strengthened. This can improve the development and management of urban forest in China and in other developing countries.     

Forest Management Patterns in the Floodplain of the Amazon Estuary

In the Amazon basin, few studies have focused on environmentally sound land-use alternatives that are linked to markets. This paper analyzes land uses carried out by traditional inhabitants ( ribeirinhos ) on three islands in the Amazon estuary. Management of the native floodplain forest is the most extensive form of land use on these islands. Such management varies in response to local economic and ecological conditions but invariably targets key nontimber forest resources destined for local markets, requires minimal input of labor and capital, and maintains a considerable stock of biotic resources. While restricted to a specific forest type, this form of land use is associated with relatively high population densities and, if supported by appropriate development policies, could provide an environmentally sound land-use alternative for hundreds of thousands of rural inhabitants of Amazonia.     

Effects of national forest‐management regimes on unprotected forests of the Himalaya

Globally, deforestation continues, and although protected areas effectively protect forests, the majority of forests are not in protected areas. Thus, how effective are different management regimes to avoid deforestation in non‐protected forests? We sought to assess the effectiveness of different national forest‐management regimes to safeguard forests outside protected areas. We compared 2000–2014 deforestation rates across the temperate forests of 5 countries in the Himalaya (Bhutan, Nepal, China, India, and Myanmar) of which 13% are protected. We reviewed the literature to characterize forest management regimes in each country and conducted a quasi‐experimental analysis to measure differences in deforestation of unprotected forests among countries and states in India. Countries varied in both overarching forest‐management goals and specific tenure arrangements and policies for unprotected forests, from policies emphasizing economic development to those focused on forest conservation. Deforestation rates differed up to 1.4% between countries, even after accounting for local determinants of deforestation, such as human population density, market access, and topography. The highest deforestation rates were associated with forest policies aimed at maximizing profits and unstable tenure regimes. Deforestation in national forest‐management regimes that emphasized conservation and community management were relatively low. In India results were consistent with the national‐level results. We interpreted our results in the context of the broader literature on decentralized, community‐based natural resource management, and our findings emphasize that the type and quality of community‐based forestry programs and the degree to which they are oriented toward sustainable use rather than economic development are important for forest protection. Our cross‐national results are consistent with results from site‐ and regional‐scale studies that show forest‐management regimes that ensure stable land tenure and integrate local‐livelihood benefits with forest conservation result in the best forest outcomes.     

What motivates farmers to participate in sustainable agriculture? Evidence and policy implications

Sustained growth in agricultural productivity has become an ideal model and a political goal of agricultural development in China. Local participation is essential for the implementation of sustainable agriculture strategy. We conducted a case study in Hailun County, an important grain production base in China, to find ways to motivate farmers to participate in sustainable agriculture. We obtained data from semi-structured interviews of 98 households using participatory rural appraisal methods. Logistic regression models were used to explore factors that underlie farmers' attitudes towards agricultural production and their environmental awareness. Results indicated that low agricultural economic efficiency could result in less enthusiasm for agriculture among local farmers. This is a potential risk for China's food security and sustainable agricultural development. The backward development of the rural economy limited improvement of farmers' environmental awareness. Moreover, poor rural labour quality implied a lack of local participation in sustainable agriculture. Suggestions for sustainable agricultural development include establishment of a reasonable market and agricultural subsidy mechanisms, basic and vocational education for young adults, effective agricultural instruction and environmental education agencies and two-way communication mechanisms.     

Site-specific and integrated adaptation to climate change in the coastal mangrove zone of Soc Trang Province, Viet Nam

The dynamic coastline of Soc Trang Province in the Mekong Delta of Viet Nam is in most parts protected from erosion, storms and flooding by a narrow belt of mangroves. However, the unsustainable use of natural resources and development in the coastal zone is threatening the protection function of this forest belt. This situation is exacerbated by the impacts of climate change, particularly by the increased intensity and frequency of storms, floods and by rising sea levels. Based on analysis of past experience of mangrove planting and historical changes in mangrove cover, an integrated and site-specific approach to adaptation to climate change has been put in place, which comprises mangrove planting and rehabilitation with emphasis on resilience to climate change, and participatory involvement of local communities in effective mangrove management and protection through co-management. To address uncertainties associated with the impacts of climate change, testing of new mangrove planting techniques has started. This includes mimicking successful natural regeneration for small-scale planting in sites with high wave energy and transformation of existing even-aged plantations into more diverse forests—both in terms of structure and species composition. The pre-requisite for mangrove rehabilitation in erosion sites has successfully been put in place: breakwaters made from bamboo have reduced erosion and stimulated sedimentation. The design and construction of the wave-breaking structures, which was based on a numerical model which simulates hydrodynamics and shoreline development, ensures that downdrift erosion can be avoided as far as possible. A comprehensive monitoring program has been established and initial results provide evidence for the effectiveness of the bamboo breakwaters. Early experience shows that co-management is an effective way of maintaining and enhancing the protection function of the mangrove forest belt and at the same time providing livelihood for local communities. Payment for ecosystem services contributes to sustainability of co-management as well as livelihood improvement.     

The Northwest Forest Plan as a Model for Broad-Scale Ecosystem Management: a Social Perspective

Abstract:  I evaluated the Northwest Forest Plan as a model for ecosystem management to achieve social and economic goals in communities located around federal forests in the U.S. Pacific Northwest. My assessment is based on the results of socioeconomic monitoring conducted to evaluate progress in achieving the plan's goals during its first 10 years. The assessment criteria I used related to economic development and social justice. The Northwest Forest Plan incorporated economic development and social justice goals in its design. Socioeconomic monitoring results indicate that plan implementation to achieve those goals met with mixed success, however. I hypothesize there are two important reasons the plan's socioeconomic goals were not fully met: some of the key assumptions underlying the implementation strategies were flawed and agency institutional capacity to achieve the goals was limited. To improve broad-scale ecosystem management in the future, decision makers should ensure that natural-resource management policies are socially acceptable; land-management agencies have the institutional capacity to achieve their management goals; and social and economic management goals (and the strategies for implementing them) are based on accurate assumptions about the relations between the resources being managed and well-being in local communities. One of the difficulties of incorporating economic development and social justice goals in conservation initiatives is finding ways to link conservation behavior and development activities. From a social perspective, the Northwest Forest Plan as a model for ecosystem management is perhaps most valuable in its attempt to link the biophysical and socioeconomic goals of forest management by creating high-quality jobs for residents of forest communities in forest stewardship and ecosystem management work, thereby contributing to conservation.     

Avoiding Re‐Inventing the Wheel in a People‐Centered Approach to REDD+

One important debate regarding Reducing Emissions from Deforestation and Forest Degradation (REDD+) in developing countries concerns the manner in which its implementation might affect local and indigenous communities. New ways to implement this mechanism without harming the interests of local communities are emerging. To inform this debate, we conducted a qualitative research synthesis to identify best practices (BPs) from people‐centered approaches to conservation and rural development, developed indicators of BPs, and invited development practitioners and researchers in the field to assess how the identified BPs are being adopted by community‐level REDD+ projects in Latin America. BPs included: local participation in all phases of the project; project supported by a decentralized forest governance framework; project objectives matching community livelihood priorities; project addressing community development needs and expectations; project enhancing stakeholder collaboration and consensus building; project applying an adaptive management approach; and project developing national and local capacities. Most of the BPs were part of the evaluated projects. However, limitations of some of the projects related to decentralized forest governance, matching project objectives with community livelihood priorities, and addressing community development needs. Adaptive management and free and prior informed consent have been largely overlooked. These limitations could be addressed by integrating conservation outcomes and alternative livelihoods into longer‐term community development goals, testing nested forest governance approaches in which national policies support local institutions for forest management, gaining a better understanding of the factors that will make REDD+ more acceptable to local communities, and applying an adaptive management approach that allows for social learning and capacity building of relevant stakeholders. Our study provides a framework of BPs and indicators that could be used by stakeholders to improve REDD+ project design, monitoring, and evaluation, which may help reconcile national initiatives and local interests without reinventing the wheel.

The progress and challenges in sustainable forestry development in China

Forestry development in China has undergone a series of reforms over the past six decades. This article examines temporal changes in forest resources and policies, the current status of forestry, and future challenges toward sustainable forest management in China. Excessive logging in the 1950s to 1980s badly damaged the nation’s forests, but the adoption of enlightened forest policies in the late 1990s has led to increases in China’s total forest area and growing stock. Forest degradation was ecologically and economically costly, and rehabilitation processes have become increasingly more expensive. The low quality and young age of forest resources, loss of natural forests, and more difficulties in afforestation and reforestation pose severe challenges for China’s sustainable forestry. It is critically important for China to enhance forest productivity through intensive management, strengthen enforcement, and educational programs for protecting and restoring natural forests, narrow the gap between domestic timber supply and rapidly expanding consumption, improve coordinating networks for management, finance, and technology transfer, and accelerate efforts to clarify and stabilize tenure arrangements for non-state forests. China’s experience and lessons in forestry may be helpful for other developing countries that are seeking to achieve the goal of sustainable forest management.

People’s dependency on forest resources and contributions of forests to the livelihoods: a case study in Chittagong Hill Tracts (CHT) of Bangladesh

The study was conducted to investigate people’s forest dependency and contributions of forests to the livelihoods in the three hill districts of Chittagong Hill Tracts (CHT), Bangladesh. The study revealed that forest resources contribute significantly to rural community’s livelihoods and economic well-being. Using generalized logistic regressions, this study has also investigated the socioeconomic factors that affect people’s dependency on forest resources of CHT. The study revealed that people’s income from forest and forest-related occupation was positively aligned with their forest dependency. However, their education level significantly reduced their dependency on forest resources. Thus, educating the forest-dependent people and supporting alternative income generation activities should be appreciated for effective forest management in CHT. This study will be helpful to forest and environmental policy makers for CHT.     

The significance of social capital in local forest management in Laos: Overcoming latent conflict between local people and local forestry officials

Forest policies that devolve forest-use rights to local people have undergone development over the past few years in Laos. As collaboration between local people and forestry officials is seen as indispensable to effective and sustainable local forest management, the objective of this study is to clarify the issues pertinent to the resolution of latent conflict between these two stakeholders. The issues are examined by presenting two case studies in terms of forest management as perceived by local people and forestry officials; the first in a rich forest area and the second in a degraded forest. Issues relating to land and borders and social capital are identified as the most important in the degraded forest area, while social capital is a very important issue in the rich forest area. Our studies show that the problems of land and border issues in the degraded forest area were caused by an inappropriate resettlement policy. This can be interpreted as the mismanagement of social capital, and for effective local forest management it is very important to overcome problems of this nature. The effective use of social capital has so far been overlooked, however, in the establishment of collaborative forest governance at the local level.     

Current situation and development of Chinese urban forestry

This paper introduces Chinese urban forestry research in terms of the concept, forest types, ecosystem services, spatial structure, planning and construction, assessment and management. Modern Chinese urban forest had a close relationship with traditional landscape architecture. Urban forest services had been quantified in some case cities, and determined by urban forest spatial patterns and internal structures. Based on landscape ecology and urban planning, urban forest spatial patterns have been analysed and planned rationally in some cities. However, studies on urban forestry generally lack long-term, continuous and systemic observations, as well as in-depth research on ecological processes and mechanisms. The development trends in urban forestry in China might include extensive application of '3S' technology, research on the relationship between urban forest landscape spatial patterns and their ecological effects, economic assessment, ecological and economic benefits and studies on the negative effects of pollutants.     

Public Timber Supply, Market Adjustments, and Local Economies: Economic Assumptions of the Northwest Forest Plan

Abstract:  The Northwest Forest Plan in the Pacific Northwest sought to stabilize local economies, including local employment and income, by stabilizing the flow of wood fiber from public forests. This is also a common forest management objective in other regions and countries. Because this economic strategy ignores basic market adjustments, it is likely to fail and to unnecessarily damage forest ecosystems. Application of basic economic principles on how markets operate significantly changes the apparent efficacy of efforts to manage local economies by managing timber supply. The emphasis on timber supply tends to ignore the dominant role that the demand for wood fiber and wood products, rather than wood-fiber supply, plays in determining levels of harvest and production. Contemporary economics indicates that markets tend to operate to offset reductions in wood-fiber supply. This significantly moderates the economic cost of reducing commercial timber harvest in the pursuit of environmental objectives. In addition, contemporary economic analysis indicates that the economic links between natural forests and local communities are much broader than simply the flow of commercially valuable logs to manufacturing facilities. At least in the United States, the flow of environmental services from natural forests has increasingly become an amenity that has drawn people and economic activity to forested areas. Attractive site-specific qualities, including those supported by natural forests, can potentially support local economic development even in the face of reduced timber harvests. These market-related adjustments partially explain the Northwest Forest Plan's overestimation of the expected regional impacts associated with reduced federal timber supply and the ineffectiveness of the plan's efforts to protect communities by stabilizing federal timber supply.     

Rural Development and Sustainable Wildlife Use in Peru

Abstract: Tropical conservation has seen a convergence between conservation projects and rural development, with both approaches promoting participation of local people in sustainable resource use. But there is a discord between rural development and sustainable use of wildlife. Implementing more sustainable use of wildlife usually means decreased economic benefits for rural people, especially over the short term. In contrast, rural-development projects are often mandated to generate income for rural people over the short term. We examined this dilemma through an integrated economic and harvest analysis of the costs associated with converting unsustainable hunting to more sustainable hunting in the Peruvian Amazon. Our analysis suggests that a change in hunting practice would have significant economic costs for rural people and would result in a 36% decrease in the economic benefits they derive from wildlife hunting. In contrast, converting unsustainable hunting to more sustainable hunting would have little effect on meat markets in the urban center of Iquitos, Peru, with markets losing only 3.6% of their economic value. There would be no economic costs for the international pelt trade. If rural-development projects absorb the short-term economic costs, they can help people convert unsustainable wildlife use to more sustainable use and assist rural people in realizing the long-term benefits of more sustainable hunting. But many rural-development projects would need to change their mandate for short-term income generation to incorporate the realities of sustainability.

农户能源利用方式的选择与农村环境的变化:某贫困山村薪炭林利用案例研究

为了深入了解农户能源利用状况与农村环境的相互作用关系,对一个贫困山村进行了为期15天的实地考察。通过问卷调查,入户访谈等方式,收集了50余份问卷和大量原始数据、图片资料,发现当地农户在利用薪材能源作为燃料直接燃烧时并不会带来对当地森林资源的破坏,但能源利用效率不高;而在用薪材能源作为香菇培养基原料时显著地提高了能源利用效率,却也严重影响了当地森林资源的可持续利用。由此可见,能源利用方式的选择与农村环境的变化息息相关。为了保证农村能源的可持续利用,人们需要同时考虑农村环境的承载能力,这就决定了改善农户能源利用状况不能单纯以提高能源利用效率为目标。在结合当地客观条件,综合当地政府、当地农户的意见的基础上,提出了当地能源利用的最佳方向应该是:在不增加农民支出前提下,鼓励农民改善薪材能源的利用方式,力图达到提高能源利用效率和森林资源可持续利用的“双赢”目的。     

Assessment of sustainability performance on the utilization of Agave (Agave salmiana ssp crassispina) in Zacatecas,Mexico

Agave is a native plant utilized for mezcal and tequila production. Since 1997, Agave exploitation has been increasing, leading to possible ecological deterioration and without social and economic benefits for the rural population. A sustainability index was developed for 1990–2001, including social, economic and ecological indicators related to Agave exploitation at Zacatecas, Mexico. Increases in the rural population have had a negative effect on Agave sustainability, directly affecting the ecological component of sustainability. Increased Agave exploitation has not improved the socio-economic components and has negatively affected the ecological indicators. All these factors resulted in a low (= 0.6) sustainability index. A lack of appropriate management may have led to the exploitation of native plants, leading to ecological deterioration of the local plant populations, without contributing to socio-economic improvement for the human population. The model using the sustainability index may also be validated for other species within this region.     

Using MCA tools for evaluating community-managed forests from a green economy perspective: lessons from Nepal

ABSTRACT

Nepal is in the process of formulating its forest policies at the provincial level . Various community-managed forests have been designed in the past by the Nepal government to decentralize the forest for its sustainable management practice. This study facilitates the process of identifying appropriate forest management options in two of the provinces, namely Provinces Three and Gandaki. Four forest management options – passive, active, scientific and multiple – were identified following the existing management practices. For the evaluation of the overall performance of the options, a framework with three criteria, 10 indicators and 28 verifiers were designed. The framework followed the green economy perspective considering the improvement of the forest conditions, economic and social well-being, and low carbon emission. The Analytical Hierarchy Process was used to prioritize the best management option and analyse trade-offs to guide future decision-making and reduce the risk of unwanted consequences. Our results show that the elicitation of preferences for the evaluation criteria varied by stakeholder groups. Their preference was largely guided by improving the forest resource condition and economic well-being. Foresters prefer scientific and active forest management, policymakers prefer multiple-use forest management and scientific management, whereas community forest user groups prefer active forest management. We argue that a scientific management approach may contribute better to economic aspects, although it may often compromise the other aspects. The multiple forest management option seems to be the best for green economy considering ecological, economic and social consequences.     

Ecological footprint and biological capacity time series assessment for a forest region in northeastern China

Anthropogenic disturbances have caused major landscape changes in the forests of northeastern China during the past 50 years. In particular, continuous over-deforestation has greatly decreased the region's forest quality. Ecological footprint analysis generates aggregated information about a population's demand on nature and the population regional biological capacity. To show the forest change and the population's ecological demand on the study area, this paper presents an ecological footprint time series for the Songling Forestry Bureau in northeastern China from 1965 to 2000. The paper shows conventional ecological footprint time series and area demand time series – under global, Chinese and local yearly yields – to study the biological productivity of Songling. In this study, biological capacity was calculated based on a conventional approach. The results demonstrate that the ecological footprint has increased slightly and continuously during the 35-year timespan, while the biological capacity has decreased dramatically. These effects have been caused mainly by the depletion of forest resources. The results also yield much information about natural changes and socioeconomic dynamics, as well as the driving factors for these changes, of which the most important is forest management policy.     

Empirical analysis on the influence of the Shaanxi fruit industry on regional food security

As part of its development policy to relieve rural poverty in west China, the Chinese government has introduced measures such as agricultural tax exemptions, agricultural subsidies, and scientific, technological and restructuring improvements to agriculture. Following these actions, farmers’ incomes have increased greatly and the economy in poor areas of west China has seen rapid improvements. However, agricultural restructuring, infrastructure construction and ecological restoration projects have reduced the area of land under arable farming, restricting opportunities for increasing total grain yield. Regional food security is therefore threatened and an imbalance between economic development and food security is created. Shaanxi is a representative province in west China where agricultural restructuring has resulted in large areas of arable land being converted into orchards that produce higher economic returns. This study randomly surveyed 1430 farm households in three counties in the apple-producing region of Shaanxi Province (Luochuan, Changwu and Baishui). The standard of living and household income of farmers in the fruit production areas were higher than in grain-producing areas, thus discouraging grain production. Land under agriculture in the counties studied comprised 59% orchards and 39% arable, with 2% under other uses. Per capita, 204.3 kg of grain was produced, 51% of that required for self-sufficiency. Other staple foods produced amounted to only 13.9% of that needed for self-sufficiency. As a result, nearly half of the grain needed by the community was purchased from outside, resulting in very poor regional food security. Clearly, fruit production in this region seriously affects regional food security. Coordination of relationships between rural economic development and regional food security is key for sustainable development of the regional agriculture and economy of west China.
