Beyond Reaping the First Harvest: Management Objectives for Timber Production in the Brazilian Amazon

CONSERVATION BIOLOGY, Issue 4 2007
DANIEL J. ZARIN
manejo de bosques; producción sostenida; sustentabilidad; tala de impacto reducido Abstract:,Millions of hectares of future timber concessions are slated to be implemented within large public forests under the forest law passed in 2006 by the Brazilian Congress. Additional millions of hectares of large, privately owned forests and smaller areas of community forests are certified as well managed by the Forest Stewardship Council, based on certification standards that will be reviewed in 2007. Forest size and ownership are two key factors that influence management objectives and the capacity of forest managers to achieve them. Current best ecological practices for timber production from Brazil's native Amazon forests are limited to reduced-impact logging (RIL) systems that minimize the environmental impacts of harvest operations and that obey legal restrictions regarding minimum diameters, rare species, retention of seed trees, maximum logging intensity, preservation of riparian buffers, fire protection, and wildlife conservation. Compared with conventional, predatory harvesting that constitutes >90% of the region's timber production, RIL dramatically reduces logging damage and helps maintain forest cover and the presence of rare tree species, but current RIL guidelines do not assure that the volume of timber removed can be sustained in future harvests. We believe it is counterproductive to expect smallholders to subscribe to additional harvest limitations beyond RIL, that larger private forested landholdings managed for timber production should be sustainable with respect to the total volume of timber harvested per unit area per cutting cycle, and that large public forests should sustain volume production of individual harvested species. These additional requirements would improve the ecological sustainability of forest management and help create a stable forest-based sector of the region's economy, but would involve costs associated with lengthened cutting cycles, reduced harvest intensities, and/or postharvest silviculture to promote adequate growth and regeneration. Resumen:,Bajo la nueva ley forestal aprobada en 2006 por el Congreso Brasileño, millones de hectáreas de bosques públicos están destinadas a constituir futuras concesiones madereras. Millones de hectáreas adicionales de extensos bosques privados y áreas reducidas de bosques comunitarios están certificadas por el Forest Stewardship Council por su buen manejo, con base en estándares de certificación que serán revisados en 2007. La extensión y tenencia del bosque son dos factores clave que influyen en los objetivos de manejo y en la capacidad de los manejadores para alcanzarlos. Las mejores prácticas ecológicas actuales para la producción de madera en los bosques de la Amazonía Brasileña están limitadas a sistemas de tala de impacto reducido (TIR) que minimizan los impactos ambientales de las operaciones de cosecha y que obedecen restricciones legales en relación con los diámetros mínimos, las especies raras, la retención de árboles semilla, la máxima intensidad de tala, la preservación de amortiguamientos ribereños, la protección del fuego y la conservación de vida silvestre. En comparación con la cosecha convencional, depredadora, mediante la cual se obtiene >90% de la producción de madera en la región, la TIR dramáticamente reduce el daño y ayuda a mantener la cobertura del bosque y la presencia de especies de árboles raras, pero los actuales lineamientos de TIR no aseguran que el volumen de madera removida pueda ser sostenido en futuras cosechas. Consideramos que es contraproducente esperar que los pequeños propietarios suscriban límites a la cosecha más allá de la TIR; que los bosques privados manejados para la producción de madera debieran ser sustentables respecto al volumen total de madera cosechada por unidad de área por ciclo de corte; y que los bosques públicos deberían sustentar el volumen de producción de especies individuales. Estos requerimientos adicionales mejorarían la sustentabilidad ecológica del manejo de bosques y ayudaría a crear un sector forestal estable en la economía regional, pero implicarían costos asociados con la prolongación de los ciclos de corte, la reducción de las intensidades de cosecha y/o la silvicultura postcosecha para promover el crecimiento adecuado y la regeneración.

Should we measure corporate social responsibility?

CORPORATE SOCIAL RESPONSIBILITY AND ENVIRONMENTAL MANAGEMENT, Issue 1 2003
Dr Jouni Korhonen
This paper is critical towards efforts that try and measure corporate social responsibility (CSR). A critical approach can be important for the development of the theory of the emerging field of corporate social responsibility. A critical and provocative approach can generate discussion and debate. Three main points of critique are presented toward the current efforts in the literature to measure corporate contributions to economic, social and ecological sustainability. First, the use of the concepts of eco-efficiency and eco-efficacy in measuring corporate contributions to sustainability are criticized from the viewpoint of the complementarity relation of human-manufactured capital, natural capital and social sustaining functions. Second, the use of measures that focus on an individual process or an individual company are reconsidered with an approach to industrial and firm networks. Third, the use of the monetary value is reconsidered, e.g. by suggesting an approach based on physical material and energy flows and on a new paradigmatic foundation for social responsibility. The social and ecological indicators illustrating the social and environmental impacts of economic activity and of firms can be combined with economic indicators, but not expressed in monetary terms.

Politics, Plurality and Problemsheds: A Strategic Approach for Reform of Agricultural Water Resources Management

DEVELOPMENT POLICY REVIEW, Issue 6 2007
Peter P. Mollinga
Starting from the assessment that past efforts at reform in agricultural water management in developing countries have achieved very little, this article argues that a fundamental change is required in the approach to policy and institutional transformation if the present deadlock in the internalisation of ecological sustainability, human development/poverty alleviation and democratic governance into the ,core business' of water bureaucracies is to be overcome. ,Social engineering' approaches need to be replaced by ,strategic action' approaches that acknowledge the inherently political character and the plurality of actors, institutions and objectives of water management , a perspective operationalised here around the notions of ,problemshed' and ,issue network'.

The Illusion of Equity: An Examination of Community Based Natural Resource Management and Inequality in Africa

GEOGRAPHY COMPASS (ELECTRONIC), Issue 9 2010
Cerian Gibbes
This article examines the dual goals of community based natural resource management (CBNRM) as a way to protect the environment (specifically wildlife) and enhance the socio-economic equity of communities. As described in the literature, CBNRM should integrate ecological sustainability, economic efficiency and social equity (Pagdee et al. 2006). Although occasionally successful at the first two ideal objectives, the enhancement of social equity is often wanting due to a priori assumptions about communities and resource management devolution. This article based largely on published literature, and addresses the constraints and opportunities for successful CBNRM in Africa, largely focusing on southern Africa as that part of the world has been one of the early testing grounds for these environmental management ideas.

Recovery of bird populations after clearfelling of tall open eucalypt forest in Western Australia

JOURNAL OF APPLIED ECOLOGY, Issue 5 2001
M.R. Williams
Summary 1Increasing concern over the sustainable management of forested landscapes and the extent of forest clearance world-wide has led to a growing interest in the impacts of logging and associated habitat disturbance on biodiversity. 2We conducted an experimental study of the impact of clearfelling on birds of the karri Eucalyptus diversicolor forest in south-west Western Australia over a 17-year period, and a retrospective study of both clearfelled and naturally regenerated karri stands aged from 0 to 146 years. 3One-third of species still had significantly reduced abundance 14 years after disturbance ceased, although all affected species made limited use of regenerating forest. 4Multivariate analysis of changes in bird community structure showed that the effects of disturbance were still evident 14 years after clearfelling. Clearfelling may also have produced some temporary changes in community structure in adjacent unlogged forest. 5Species richness and total abundance of birds declined by 58% and 96%, respectively, in the first year after clearfelling, and 14 years after logging were still 17% and 55% below levels in adjacent undisturbed forest. During this early successional phase both measures increased as a simple function of stand age. Species richness of regrowth reached that of old-growth at 30,50 years and total abundance of all bird species in regrowth was similar to that of old-growth after approximately 70 years. 6Several bird species offer potential as indicators of the ecological sustainability of karri forest management. These species nest in large hollows in standing live trees (two cockatoo species) or have been slow to recolonize immature regrowth karri forests (six species). 7Post-hoc power analysis showed that even the long-term and intensive sampling employed in this study failed to detect declines in abundance of less than 80,90% for most bird species. For many uncommon species, trying to estimate changes in abundance is problematic and likely to require replication which is difficult to achieve in field situations where logged and unlogged forests are compared. Despite this, the present study identified some key impacts of forest clearfelling on bird communities, with implications both for the consequences of clearfelling of forests and the criteria for sustainable forest management.

Modern Interpretations of Sustainable Development

JOURNAL OF LAW AND SOCIETY, Issue 1 2009
Andrea Ross
Early interpretations of sustainable development based on weak sustainability address neither the limits to the earth's resilience nor our failure to curb consumption. Given the challenges facing the earth today, especially climate change, a much more meaningful instrument is required and a new ethic based on the ecological carrying capacity of the Earth. The article examines the impact of those early interpretations before exploring the importance of ecological sustainability as the moral and (potentially fundamental) legal principle underpinning the concept of sustainable development. It examines the influence of the climate change agenda before examining the mechanisms available to make this ethic operational. Sustainable development has the capacity to set meaningful objectives, duties and rules, and provide boundaries for decision making, as reflected in recent legislation. Enhancing ecological sustainability through improving supply and impact is relatively easy for governments, businesses, and individuals; reducing consumption is much harder, and will require strong leadership.

Contrasting Institutional and Performance Accounts of Environmental Management Systems: Three Case Studies in the UK Water & Sewerage Industry*

JOURNAL OF MANAGEMENT STUDIES, Issue 4 2007
Anja Schaefer
abstract This paper presents results from a longitudinal, qualitative study into the adoption of environmental management systems (EMS) in three companies in the UK water & sewerage industry. Based on institutional theory and the literature on EMS, four factors related to the adoption of EMS are identified: external and internal institutional forces, environmental performance issues, and economic performance issues. While previous literature has often assumed a balance of performance and institutional factors or a preponderance of performance factors, the results of this study indicate that institutional forces are the predominant drivers. The results further indicate that environmental performance issues become less important over time, whereas institutional drivers and economic performance rationales increase in importance over time. While conforming to institutional pressures can result in improved economic performance of a company, adoption of environmental management systems mostly on the basis of institutional and economic factors has wider repercussions for the state of corporate environmental management and progress towards greater ecological sustainability of business.

MCDM methods in strategic planning of forestry on state-owned lands in Finland: applications and experiences

JOURNAL OF MULTI CRITERIA DECISION ANALYSIS, Issue 5 2001
Jyrki Kangas
Abstract The forests in Finland have been under intensive planning for decades. Currently, mathematical programming is widely used in planning of wood production. Today's multi-functional forestry, however, calls for more flexible decision support methods. MCDM tools have been used in responding to fresh planning challenges. For example, the Finnish Forest and Park Service, entrusted with the care of the vast majority of state-owned natural resources in Finland, endeavours to produce large-scale natural resource plans satisfying the needs of both economic, social, and ecological sustainability. Participatory approach is applied in the process. Several forestry applications of MCDM methods, particularly those making use of the AHP or the HIPRE program, have been presented. Also, the outranking methods ELECTRE and PROMETHEE have been tested. Due to the nature of forestry applications, statistical techniques for analysing uncertainties in pairwise comparisons and for utilizing interval judgement data have been developed to improve the usability of the AHP. Recently, a hybrid method called A'WOT, making use of the AHP and SWOT, was also introduced into strategic forest planning. This paper summarizes the experiences gained in applying a MAVT and two outranking methods in connection with a participatory natural resource planning process in Finland. In addition, some results of the method development work related to application needs are briefly presented. The details of the planning cases reviewed here have previously been presented in forestry journals. The purpose of this paper is not only to show how MCDM methods have been applied in forestry, but also to discuss the usability and usefulness of MCDM methods from the viewpoint of supporting forestry decision making,and how they might further be improved. Also, some perspectives for the future development work of MCDM applications in the field of natural resource management are focused on. As a conclusion, the use of more than just one MCDM method in a single planning process is seen usually recommendable. In addition, developing hybrid MCDM methods is regarded as a potential direction for future research. Also, closer co-operation between method developers and appliers is called for to produce more useful applications. Copyright © 2002 John Wiley & Sons, Ltd. [source]

Corporate engagement in processes for planetary sustainability: understanding corporate capacity in the non-renewable resource extractive sector, Australia

BUSINESS STRATEGY AND THE ENVIRONMENT, Issue 8 2007
Neil Harris
Abstract In recent years corporations have come under increasing pressure from governments, consumers, investors, competitors, business partners and communities to balance their pursuit of economic gain with environmental and social concerns. Non-renewable resource extractive corporations in particular, due to their profile, visibility and activities, have come under mounting pressure to embed the concept of ecological sustainability into strategic decision-making processes and operations. In this regard, there is a growing base of evidence that describes efforts, successes and failures in the sector to meet mounting societal expectations. However, to date there has been limited explanatory research into corporate capacity to engage in processes for ecological sustainability. This paper presents an emergent explanation of the internal factors mediating corporate engagement in ecological sustainability in non-renewable resource extractive corporations in Australia. It identifies the five factors of leadership, resources, structures, culture and understanding and conceptualizes these internal factors as capacity for engagement. While all of the factors are seen as interdependent and essential, leadership is identified as the most critical. Copyright © 2005 John Wiley & Sons, Ltd and ERP Environment. [source]
