Abstract

New tools and forms of cooperation at the landscape level are needed in order for forestry and environmental conservation to co-exist in areas with many land owners. Awareness has existed for several years in Sweden that cooperation at the landscape level is essential for protecting areas of high environmental value. This awareness has come to expression in several projects and initiatives. One of these projects is the Östra Vätterbranterna Partnership, a successful example of the new orientation toward environmental management as formulated in the government bill Sustainable protection of nature areas: new working methods with a focus on collaboration and increased dialog by involving more actors and utilizing a greater combination of steering instruments. This development resonates with the growing trend toward deregulation and less state intervention in environmental management, implying a stronger emphasis on new governance structures and market-driven processes. This paper examines the preconditions for a development toward governance-oriented forms of steering in the area of environmental policy and law, with specific emphasis on the protection of forestry areas with high environmental value. Paralleling this development, the transformation of environmental public administration is analyzed, using a model representing three different perspectives on administration's role, values and meaning, showing state action's progressive transition from “rowing” to “steering” to “serving” and facilitating.  相似文献

ABSTRACT

Industrial production of beef, soybeans, cotton, and biofuels is expanding into the tropical latitudes of South America and may soon reach tropical Africa in the most important agricultural transition since the Green Revolution. This shift is driven by the shortage of land suitable for expansion of cultivation and grazing in the temperate zone, increased global demands for agricultural commodities, the rising price of petroleum, and technological advances. At risk are some of the world's most ecologically and culturally-rich landscapes in the world, such as the Amazon rainforest, the Cerrado woodland complex, and African savannas. A strategy for reducing the negative ecological and social impacts of this transition could harness the rising environmental and social standards imposed by many importers and purchasers of agricultural commodities, similar reforms underway among “Equator” banks, growing corporate governance, and Brazil's prominence in international diplomacy. Integrated certification of commodity sanitation, compliance with rigorous environmental standards, and sound labor practices could become the norm for participation in commodity markets. These reforms in agro-industrial behavior could be reinforced by trade agreements and strategic support from non-governmental organizations.  相似文献

ABSTRACT

Watersheds have become strategically important for the survival of cities due to the accelerated increase in both the demand and the rapid deterioration of the water intended to supply the urban populations. The present article aims to present the applicability of the “multicriteria method” to help the Government of the State of Sao Paulo, Brazil organize payment for environmental services for watershed protection using the “Delphi method” as the principal methodology. This article consists of a review of the literature and a case study of the Mina d’Água program from the State Secretary of the Environment (within the Government of São Paulo) in partnership with other municipalities (city by river basin). The article also covers the advent of pertinent climate change laws. The positive results in the use of the Delphi method represent a fruitful tool to facilitate communication between groups of experts and the public, encouraging better judgment and a more consistent decision-making process.  相似文献

Vast areas of dry subtropical evergreen forests of Olea cuspidata in the northwestern mountains of Nepal have been abandoned in recent decades. The status of this species was found to be very poor in almost all the areas of our study sites, located in Bajura district. However, the lack of past information on this species did not allow us to determine the exact number of hectares that have declined. Overgrazing, illegal cuttings, and lack of environmental awareness were found to be the major causes of Olea spp. forest degradation. Direct survey and Geographic Information System (GIS) methods were used to create a current distribution map of wild olive. Potential sites based on the sparse population and dense patches of wild olive were still found in Bajura. A large amount of wild olive fruit was found unused in these area. If properly managed, subsistence farming of this fruit can be an income supplement for the poorest and vulnerable local communities. The scope of our study was to map the vulnerable status of one of the International Union for Conservation of Nature (IUCN)-listed wild olive species from the remote far-western district of Bajura. The necessity of an immediate national policy is discussed to develop and consolidate control techniques and ecological restoration strategies based on conservation and sustainable approaches in order to prevent future decline of native plant diversity.  相似文献

Abstract

“Sustainability” is used as a catchword, with different meanings depending on the actor. This paper examines how the term “sustainability” is used by the Brazilian pulp maker Veracel Cellulose, and other major cellulose pulp producers in South America, and the cleavage between the companies and the local communities in their understanding of the term sustainability. The analysis was based on annual or sustainability reports from companies in Brazil (Aracruz, Fibria, Suzano and Veracel) and Chile (Arauco and CPMC), and Nordic Stora Enso and UPM. The main emphasis is on Veracel for 2008 and 2009, which is contrasted with a letter to the Forest Stewardship Council (FSC) from the local Bahian NGO, CEPEDES. Although the companies use “sustainability” as a catchword, in the actual reporting the wording “environmental and social responsibility” is preferred. A new reporting standard, GRI, encourages a narrower focus on selected business-related indicators, rather than a broader view in accordance with the Brundtland and Rio definitions. The cleavage between business- and a livelihood-oriented understanding of “sustainability” reflects a difference in understanding of the underlying concept of “development”. To ensure long-term sustainability of company operations, sustainable business development of the pulp and paper industry should include local livelihood perspectives to a greater extent than at present.  相似文献

Abstract

The AMISCONDE Initiative was created and promoted by Conservation International (CI). This paper analyzes the approach to biodiversity conservation of the Costa Rican portion of the Initiative in the context of CI's mission statement. Global, national and local challenges to biodiversity conservation are briefly reviewed. Then, the implementation of the AMISCONDE Initiative is examined. To provide a basis for comparison, two other well-known Costa Rican conservation programs are summarized. The Initiative differs from these other programs in its central emphasis. AMISCONDE focuses on community development, apparently prioritizing development above biodiversity protection. The paper concludes with several recommendations: that the Initiative place far greater emphasis on biodiversity through education, employment opportunities and collaboration with other organizations interested in the biota of the region; and that the program evaluate its impact on the protected area's biota. This would enable CI to determine the degree to which the impacts of the Initiative are consistent with its mission.  相似文献

Moso bamboo (Phyllostachys pubescens) is cultivated for edible bamboo shoot production in Japan. Yamagata Prefecture is located in a heavy-snowfall region at the northern limit of the cultivated area. However, snow damage to bamboo culms occurs every year and decreases bamboo shoot production. “Uradome” is a treatment that involves cutting off the upper portion of the new culms when the bamboo shoot is almost fully grown. We studied the effect of “Uradome” implementation on incidence of snow damage to bamboo culms. In addition, we investigated terrain characteristics of bamboo forest at sites where snow damage occurred. As a result, the higher the degree of “Uradome” was, the lower the damage rate was. Furthermore, the results revealed that implementation of “Uradome” prevents snow damage to culms. It is considered that snow damage may be prevented by rendering the culm shape straight as a result of “Uradome”. The results also indicated that snow damage is more likely to occur on steep slopes. Factors that influence the incidence and severity of snow damage are considered to differ between Japan and other countries. Therefore, it is desirable to adopt preventative measures against snow damage, such as the “Uradome” method, irrespective of the local climate and terrain.  相似文献

Abstract

Consumers in today's world can perceive an additional benefit associated with responsible business practices and the sustainability of purchased products. However, in Scandinavian context, there is a lack of knowledge of consumer perceptions toward environmental and social sustainability of wood products. Our data on adult Finnish consumers (private end-users) (N=227) were collected during 2004–2007 as interview exit data from home retail centers selling building materials. The perceived environmental and social sustainability of wood products was investigated using exploratory factor analysis, and the phenomenon was observed to be a two-dimensional construct consisting of “General environmental and social sustainability” and “Specific social sustainability” reflecting strong consumer need for product safety. Logistic regression analysis revealed that the “General” dimension also explains the consumer's self-declared willingness to pay for sustainable wood products. The results also indicate that the respondents may be segmented based on their perceptions on product level environmental and social sustainability: the most environmentally and socially conscious group can be profiled by gender (female), older age, and summer cottage ownership.  相似文献

With the book publication “Forest and Nature Governance — A practice based approach” (Arts et al., 2013, Eds.) the Forest and Nature Conservation Policy Group of Wageningen University, The Netherlands demonstrates its high aspirations of developing a new research approach. This article aims at discussing the methodological and conceptual contributions of the book to the field of forest and environmental policy research and proposes perspectives for further developing this methodological approach. It finds the “practice based approach” being an innovative, theoretically sound concept, which is able to produce valuable and “thick” empirical results. The approach is also found offering a plethora of possibilities to link up to analytical policy research. Yet, the approach will require further elaboration, especially on questions regarding the role of definitions, its contribution towards explaining social phenomena, and concerning the use of normative orientations in some of the empirical cases. The future challenges of the approach lie in either moulding a niche for further developing it independent from other schools, or in influencing mainstream approaches through theoretical innovations or surprising empirical results.  相似文献

Abstract

The central question for this paper is whether land managers in Panama might protect or restore forests on their lands in response to the market for the existence value of biodiversity. Conservation financing provided by non-Panamanian sources is used as a proxy for investigating the nature of the market for the existence value of biodiversity. Debt-for-nature swaps and environmental trust funds, such as the Global Environment Facility (GEF), provide examples of demand in this market. This paper examines trends and policies that could change the cost of supplying biodiversity protection and factors that could improve or undermine demand for the existence value of biodiversity. If ecological restoration receives as much support within the conservation community as protection of pristine areas has in the past, then demand in this market is likely to remain strong. The largest challenge for this market will be shifting to the provision of biodiversity conservation by private landowners rather than solely by the national government.  相似文献

Abstract

Tropical forests are very rich in biological diversity and form an important economic and ecological resource. This biodiversity is of great value for communities living in or near these forests as a ready source of subsistence and cash income, and for the world at large as a source of tropical timber and non-timber products and a repository of genetic and chemical information. However, this biological complexity is diminishing rapidly. We analyze the main human (anthropogenic) actions causing loss of tropical forest biodiversity along with the strategies of management for forest biodiversity. Not only is the biophysical component important in management for biodiversity, but the action participation and support of local people, the national government and international cooperation as a whole, arc essential for an effective and sustainable development of tropical forests. This integrated development strategy ensures that socio-economic and environmental benefits are provided for present and future generations.  相似文献
