Sustainable development and sustainable forestry: analogies,differences, and the role of flexibility

Various approaches have been developed to achieve sustainability in forestry, under changing social needs and, consequently, changing definitions of sustainability. This has led to the confusing situation in which various groups have different understandings of the meaning of ‘sustainability’. Likewise, the concepts utilized to achieve sustainability, often with a poorly defined objective, are sometimes not clear and/or inconsistent as a systematic overview regarding definitions and concepts is lacking. Based on a literature review, this paper discusses related terms such as sustainability, sustained yield management, sustainable forestry, sustainable forest management and sustainable development: their history, concepts and relationships, from a European perspective. Finally, flexibility is proposed as a solution to overcome the identified shortcomings at all scales, while focussing on the enterprise level. The origin of the sustainability concept in forestry was first driven by forest experts, while participatory elements have been considered since the more recent idea of sustainable development. Since then, much effort has been made to achieve intragenerational fairness by creating an improved participatory process. Concurrently, the original idea of sustainable forestry as long-term and future-oriented management, considering future generations’ needs fell behind. An increasing standing timber volume in Europe and the discussion on climate change brought new interest in how to cope with risks in the context of pervasive future uncertainties within the scope of promoting sustainable development. Although the consideration of risk has been concentrated on as a topic in forest science in recent years, studies have mainly focused on the enhancement of forest resistance against disturbances. However, precaution and risk avoidance alone are probably insufficient to achieve an improved sustainable development that focuses on intergenerational fairness, as these more defensive approaches may disregard important management opportunities involved with an uncertain future. A perhaps more promising approach, the idea of future options and the ability to respond to changing social and biophysical circumstances (i.e. flexibility) as criteria for sustainable development have only shown a shadowy existence up to now. To further develop the consistency of sustainability concepts, a shift of sustainability approaches from continuity towards flexibility options is proposed.     

Forestry Out-Grower Schemes

Abstract

The trade relationship between suppliers (e.g., growers) and processors often plays an important role in determining the nature and extent of benefits derived from commercial forestry, and the distribution of these benefits. Those interested in forestry development-whether in industrialized or non-industrialized countries-are becoming increasingly aware that positive partnerships between forest companies and growers can provide a means of encouraging forest management which is environmentally sustainable, cost-efficient and equitable. Forestry out-grower schemes describe one type of partnership emerging between growers and processing companies, as the companies with inadequate forest holdings or access to public forests seek to secure additional supplies to meet the increasing global demand for wood products. However, existing out-grower arrangements vary considerably in their ability to be mutually beneficial, achieve sustainable forest management, and meet the social, technical or economic goals of the partners. This paper reports on recent research in which the authors undertook a survey and analysis of 17 forestry out-grower schemes in 11 countries to assess the extent and location of out-grower schemes world-wide and identify key parameters for successful out-growers schemes to provide guidance to forestry developers, decision makers and participants in such schemes.     

International expectations for sustainable forestry: a view from the U.S. forest industry

Today several global forces are raising expectations that forestry must be practiced on a sustainable basis. This is true for forestry as practiced in tropical, temperate, and boreal regions, as well as in developed and developing countries. Several institutional processes are in place to develop criteria for and indicators of sustainable forestry. As customers and consumers have become more knowledgeable, they are becoming more demanding about the environmental attributes of the products they buy. Forest products companies and forest landowners who wish to maintain access to these more demanding markets will need to provide assurances of their commitment to sustainable forestry practices.Forest landowners and forest products manufacturers in Washington, Oregon, and California are currently better positioned to meet these expectations than are producers in other regions. In these western states, state forest practices laws and regulations are generally consistent with emerging international criteria and indicators of sustainable management.However, U.S. competitors in such countries as Canada and Sweden are acting rapidly to establish sustainable forestry practices, and to communicate their commitments to their stakeholders and customers. The assurance of sustainable forestry practices is now the latest means by which environmentally aware and demanding customers and consumers differentiate among forest products producers.     

The shrinking profitability of small-scale forestry in Japan and some recent policy initiatives to reverse the trend

About 80% of annual wood fiber consumption in Japan is imported. Even though most of the land surface is covered by forests in Japan, the domestic forestry and forest industry are threatened by such imports flooding the local market. Fragmented land ownership, steep terrain, rapid growth of weeds, and high labor costs have all contributed to the decline of domestic forestry. Further, the purchasing power of the Japanese Yen has become very strong in recent years, and the decreasing prices of imported timber have depressed the prices of domestic timber, eroding profitability and discouraging small-scale forestry. In spite of these difficult circumstances, there are several interesting new developments in Japanese forestry. One is the revision of the Basic Forestry Law of 1964, through which the Japanese government is steering forest policy from timber production towards environmental services. Because of this change, new ways to assist rural forestry activities will become available in the near future. Another change is the certification movement, where recent examples of Japanese companies acquiring ISO 14001 and Forest Stewardship Council (FSC) forest certifications provide hope to depressed domestic forestry activities. In particular, FSC group certification is useful in motivating small-scale forest owners to implement and maintain sustainable forestry practices. This paper is based on the presentation at IUFRO Group 3.08.00 Symposium at Joensuu, Finland 2001. The original article, ‘The economic situation of small-scale forestry in Japan’, is in Niskanen and Vayrynen (2001).     

A criteria and indicator prognosis for sustainable forest management assessments: Concepts and optional policy baskets for the high forest zone in Ghana

ABSTRACT

This article establishes principles conveyed by criteria and indicators as a useful tool for measuring progress made toward sustainable forest management (SFM). Pedagogically, the conceptual construction raises questions on the following topics: (a) the various management practices and policies that exist in the high forest zone, (b) how criteria and indicators for assessments are selected, and (c) how progress made toward SFM is measured. Performance scores are established for indicators identified within the three sectors (forest ecosystems, forest communities, and the economy) for sustainability assessment. Measuring progress toward SFM operations are quantitatively performed with estimated maximum and minimum thresholds levels at which resource-use would be sustained using the Measure of Forest Resource-Use Sustainability Scale (MoFRUSS). The outcome of the measurement operations, as depicted by MoFRUSS, reveals the actual extent to which stakeholder’s initiatives toward sustainable forest management has progressed and in which direction it is moving. It also offers optional policy baskets for resource management interventions from which the socio-eco economic bundle is recommended if the forestry sector of Ghana’s Vision 2020 (sustainable development) is to be achieved with improved societal well-being, improved environmental health and vitality, and improved economic growth and development.     

1973～2003年中国林业生态足迹的研究

生态足迹是评价可持续发展能力重要指标之一,该方法自提出以来得到广泛关注和迅速应用。首先,本文分析了中国1973-2003年木材生产、进口和出口情况,结果表明,中国在1973-1995年期间木材生产呈明显波动变化趋势,1995年后呈现连续下降趋势;木材进口在1995年后特别是天然林保护工程实施后呈增长趋势,而木材出口在1995年后呈逐年下降趋势。然后,采用改进的生态足迹方法(即森林可持续产量法与森林实际生产法)计算了中国1973-2003年间的林业生态足迹(包括进口与出口林业生态足迹),分析表明,1978-1988年期间,实际生产法计算林地真实面积小于可持续产量法计算结果,而1989-2003年正相反,上述两种方法的计算结果均大于用全球产量计算的林业生态足迹。说明中国在1978-1988年间森林资源消耗量大于生长量,林业发展是不可持续的;1989年后森林资源消耗出现长大于消的局面,林业朝着可持续的方向发展,但同林业发达国家相比仍有较大的差距。最后,讨论了林业生态足迹与国家重要政策(包括外贸、经济与森林保护政策)的关系,并提出了减少林业生态足迹与增强林业可持续发展能力的几点建议。图3表1参31。     

Barriers to Sustainable Forestry in Central America and Promising Initiatives to Overcome Them

Summary

Over the past decades, Central America has suffered some of the highest deforestation rates worldwide. Vast tracts of forest have been converted to agriculture and pasture, encouraged by ill-designed government policies and perverse incentives. Recently, however, progress has been made toward more sustainable use of forest resources by adjusting forest policies, decentralizing forest administration, and providing conducive incentives through environmental service payments and forest certification. Valuable forest management experiences have been gained by indigenous and peasant communities. Community forestry in Central America is being increasingly recognized by national governments. Examples include the community concessions in Peten, Guatemala, and community-based forest operations in Honduras and Nicaragua. Stakeholder networks have been established that strengthen horizontal and vertical alliances among wood producers and manufacturers and that help promote both community development and forest conservation. However, illegal logging, poor law enforcement, and lack of economic viability of forest management involving nontraditional species still provide barriers to the sustainable management of tropical broadleaved forests in the region. Future challenges include improved governance through decentralized forest administration, private sector involvement, and third-party certification. To improve traceability and value adding, development of integrated supply chains of forest and wood products is recommended.     

Forest Policy Evolution in Poland

Abstract

In Europe, intensive forest management has anteceded a long history of intensive exploitation. The result has been the replacement of natural forests with highly productive albeit more vulnerable forests of simplified structure. Polish forestry has followed this same pattern and the country has seen a substantial increase in forest cover over the last 50 years. The main challenge for Polish forest management comes in trying to meet growing demand for wood products while responding to increased public demand for conservation of environmental values. Poland's new Forest Act for the first time puts environmental social and productive values of the forest on an equal footing. Within the framework of the Act. the Polish Policy of Sustainable Forest Development puts special emphasis on protection of biological diversity and the promotion of environmentally safe technologies and practices. The concept of Forest Promotion Areas is the major element of the Policy. The challenge for Forest Promotion Areas and for Model Forests will be to bring together all the necessary elements: environmental, economic and social that will allow sustainable development in its broadest sense.     

Forestry indemnity: a regional case study

The role of forests in the public and private spheres is the standard against which workers in the sector must measure their activities in outlining models for the use of forest resources. The actions of legislators and public administrations are aimed at identifying the intrinsic nature of forests in and of themselves (internal limits), from which flows the identification of their optimal use in terms of society and its economic interests (external limits). Additional measures have reinforced a new set of goals, which has shown a need for a new management approach with an emphasis on environmental uses, in turn calling for an indemnification to land owners for loss of income. This forest policy approach is frequently use in Italy, especially for forest with high environmental value as the forests within protected areas or in forests included in the Natura 2000 network. The workings of law 43/1974 for the Lazio region are reconcilable with this emerging model. This analysis of its 30 years of practice shows both its intrinsic potential for improving the environment, and the seriousness of its influence when it is mistakenly used to intervene in precarious ecosystems. The conclusions will highlight the circumstances and procedures for the proper use of a forestry indemnity as evidenced by the Lazio Region, pointing out the essential characteristics of a forestry policy that efficiently supports sustainable forest management. Conclusions highlighted the circumstances and procedures for the proper use of forestry indemnity, and, according to the Regione Lazio experience, certain essential characters that should typify the forest policy in order to support efficiently the sustainable forest management.     

可持续林业建设的发展方向

全球生态意识的觉醒、环境危机感的增强、森林和林业价值观念的转变，不仅对林业调查规划(设计)部门提出了更新更高的要求，而且也要求森林经营体制与规模等做出相应的转变。单纯注重森林蓄积消长量的调查和木材的培育利用，显然满足不了时代的要求，应拓宽到森林多种环境信息资源的调查和多目标的经营利用上，为此在借鉴国外先进经验的基础上，提出了森林资源调查应完善的内容和森林可持续经营所采取的措施与手段，指出成立林业公司是森林经营的一个发展出路。     

The Costa Rican Association for the Study of Native Forestry Species (CANS)

SUMMARY

In the Gran Sabana of Venezuela and the North Rupununi Savannah of Guyana, protected areas have been established primarily for purposes of conservation. However, both Canaima National Park in Venezuela and the Iwokrama International Centre for Rainforest Conservation and Development in Guyana are multiple use areas where a variety of resource use occurs and/or is planned. Shifting cultivation by the indigenous population is currently both the most common use of the forest and the use of longest duration in both areas. Surveys were conducted of paired primary and secondary forests in order to test the hypothesis that traditional, dispersed shifting cultivation with long fallows and no post-cultivation disturbance is sustainable, resulting in the eventual re-establishment of diverse secondary forests. Interviews and observations of agricultural practices and surveys of agricultural fields were conducted to determine the contemporary forest use practices and the extent to which traditional practices have changed. Results indicate that even dispersed, long fallow shifting cultivation requires careful management and several disturbance-free decades before diversity levels in secondary forests approach those in old growth. Further, that the process of integration and cultural “development” has destabilized this traditionally sustainable system in some areas. A central assumption of the paper is that with an understanding of the impacts of shifting cultivation and of the conditions under which it is sustainable, informed decisions about protected area management can be made. The data provide valuable and hitherto missing information on the levels of forest disturbance that can be sustained in the two protected areas while still meeting conservation goals.     

Guiding Principles for Small-Scale Forestry in a Watershed of the Venezuelan Andes: Constraints and Opportunities

In the Venezuelan Andes, some small-scale forest plantations have become an important resource basis for forest management. In this paper, the forestry management progress in the Mucujún river watershed is analyzed. Constraints and opportunities for sustainable management within national policies, local regulations, environmental features and social benefits are also examined. Plantation assessment, and biophysical, legal and socioeconomics information, are used for guiding small-scale forestry practices in this watershed, with emphasis on the main principles of landscape management. These plantations have become an important part of the socio-ecological landscapes with potential for wood production—in the context of low intensity and low environmental impact environmental services and amenity—because of the two protected areas within the watershed. Current forest stand conditions, however, reflect that management requires improvement. Furthermore, the analysis suggests that improvement of local livelihoods may be achieved with a small-scale forestry approach, taking properly into account the basic criteria of social involvement and management of planted forests, while maintaining ecosystem services including biodiversity and water supply.

Mitigating Climate Change Through Small-Scale Forestry in the USA: Opportunities and Challenges

Forest management for carbon sequestration is a low-cost, low-technology, relatively easy way to help mitigate global climate change that can be adopted now while additional long-term solutions are developed. Carbon-oriented management of forests also offers forest owners an opportunity to obtain a new source of income, and commonly has environmental co-benefits. The USA is developing climate change policy that recognizes forestry as a source of offsets in carbon markets, and the emissions trading programs and standards that have developed to date offer opportunities for afforestation, reforestation, reduced emissions from deforestation and forest degradation, and improved forest management projects. Private forest owners are key players in carbon markets because they own over half of the forest land in the USA and carbon offsetting from public forest land is rare. However, a number of environmental, economic, and social constraints currently limit carbon market participation by forest owners. Key issues include: the low price of carbon and high cost of market entry; whether small landowners can gain market access; how to meet requirements such as management plans and certification; and whether managing for carbon is consistent with other forest management goals. This paper provides an overview of current and emerging opportunities for family forest owners to contribute to climate change mitigation in the USA, and explores ways of overcoming some of the challenges so that they can take advantage of these opportunities.     

对中国林业可持续发展问题的基本认识

林业是环境再生产的主导产业。林业可持续发展,关键在于规范和调整林业部门的经营、管理行为。而森林的可持续经营强调通过对森林生态系统的有效经营管理。为社会经济发展提供多种物质产品和环境服务功能。中国林业发展面临着：巨大的人口压力、经济运行体制和变革、现行林业政策体系不健全,以及土地资源相对不足、水资源总量少、生态环境形势依然严峻的现实。林业发展目标取向的现实差异,要求政府建立起活当的协调机制,在保障森林经营者、部门,乃至全体公民合法权益的基础上,实现林业可持续发展社会、经济、生态环境目标的协调。关于林业可持续发展实践,一是要明显特定区域对林业的需求结构和自然基础;二是建立相应的社会、经济、生态环境目标和森林目标;三是构筑起配套的技术体系;四是完美政策保障体系。中国自然资源结构、地理特征和社会经济发展进程中,对于林产
