Poverty Alleviation and Environmental Restoration Using the Clean Development Mechanism: A Case Study from Humbo,Ethiopia

Poverty, hunger and demand for agricultural land have driven local communities to overexploit forest resources throughout Ethiopia. Forests surrounding the township of Humbo were largely destroyed by the late 1960s. In 2004, World Vision Australia and World Vision Ethiopia identified forestry-based carbon sequestration as a potential means to stimulate community development while engaging in environmental restoration. After two years of consultation, planning and negotiations, the Humbo Community-based Natural Regeneration Project began implementation—the Ethiopian organization’s first carbon sequestration initiative. The Humbo Project assists communities affected by environmental degradation including loss of biodiversity, soil erosion and flooding with an opportunity to benefit from carbon markets while reducing poverty and restoring the local agroecosystem. Involving the regeneration of 2,728 ha of degraded native forests, it brings social, economic and ecological benefits—facilitating adaptation to a changing climate and generating temporary certified emissions reductions (tCERs) under the Clean Development Mechanism. A key feature of the project has been facilitating communities to embrace new techniques and take responsibility for large-scale environmental change, most importantly involving Farmer Managed Natural Regeneration (FMNR). This technique is low-cost, replicable, and provides direct benefits within a short time. Communities were able to harvest fodder and firewood within a year of project initiation and wild fruits and other non-timber forest products within three years. Farmers are using agroforestry for both environmental restoration and income generation. Establishment of user rights and local cooperatives has generated community ownership and enthusiasm for this project—empowering the community to more sustainably manage their communal lands.     

Strategic environmental assessment as a tool of environmental governance: Scotland's extension of the European Union SEA Directive

The coverage of strategic environmental assessment (SEA) has been extended to all public sector policies, plans and programmes subject to Scottish jurisdiction. Evaluation of the arguments advanced by the Scottish Executive for using environmental assessment as a tool for environmental governance requires an exploration of some of the contested interpretations of the function of environmental assessment at a strategic level. The paper examines the implications of this extension of the European Union SEA Directive in the context of current arrangements to fit environmental assessment into the UK tradition of integrated policy appraisal. It considers the methodological implications of using SEA explicitly for improving public sector decision making at all levels and across all activities. This enables environmental effects to be taken into account at an early stage in the formulation of government policy, through a transparent system of assessment which encourages public participation.     

Accounting for risk and uncertainty in determining preferred strategies for adapting to future climate change

Individuals, businesses, and policymakers face the problem of selecting a preferred strategy for adapting a managed ecosystem to future climate change when there is risk and/or uncertainty about future climate change and its ecosystem impacts, and the conditional outcomes of adaptive strategies (i.e., performance of an adaptive strategy given a particular future climate change scenario occurs). Evaluation methods for this purpose are described for two cases; one in which the decision-maker can (climate risk case) and cannot (climate uncertainty case) assign probabilities to future climate change scenarios. Fuzzy sets are used to characterize uncertainty regarding both future climate change, and the conditional outcomes of adaptive strategies. The preferred conditional adaptive strategy for a future climate change scenario is determined by ordering the adaptive strategies for that scenario using a fuzzy set operation. Two methods are described for determining the adaptive strategy that is preferred across all climate change scenarios. The preferred overall adaptive strategy for the climate risk case is determined by maximizing a performance index for strategies. The preferred overall adaptive strategy for the climate uncertainty case is determined using the minimax regret criterion, which selects the strategy that minimizes the maximum loss in performance that can occur across all strategies and climate change scenarios. Ways for making the evaluation methods dynamic are considered.     

Privileged Narratives and Fictions of Consent in Environmental Discourse

In selecting six keywords from the environmental discourse the authors argue that language's 'double motivation' reveals a dialectical structure through which it simultaneously expresses both a utopian narrative and an ideologically driven myth of totality and consensus. The ambiguity of these keywords is of critical significance to all those involved in the environmental discourse, for without agreement on the meaning of commonly used concepts effective policy development is potentially disabled. The keywords we explore are 'community', 'sustainability', 'globalisation', 'diversity', 'democracy' and 'environment' itself.     

Individually variable energy management strategies in relation to energetic costs of egg production

Marked interindividual variation in metabolic rate suggests considerable complexity in energy management strategies, but attempts to further our understanding of the relationship between resting metabolic rate (RMR), daily energy expenditure (DEE), and reproductive effort have been hampered by the complexity of studying this system in the field. Here, we describe energy management strategies in a captive-breeding system, using Zebra Finches (Taeniopygia guttata), to demonstrate the high level of complexity and interindividual variability in energy expenditure, food intake, locomotor activity, and reproductive effort. In particular, we investigated whether the increase in RMR associated with egg production is additive, resulting in higher DEE and a need for elevated food intake, or whether this cost is compensated by reduced expenditure in nonreproductive components of the energy budget. We found high levels of intra-individual variation in energy expenditure associated with egg production in female Zebra Finches, e.g., comparing nonbreeding stage with the one-egg stage, change in RMR varied from 4.0% and 41.3%, and change in DEE varied from -33.3% to +46.4%. This variation was systematically related to aspects of locomotor activity and reproductive effort. Females with the largest increase in RMR during egg production decreased locomotor activity the most but still had increased DEE at the one-egg stage, and females with high DEE at the one-egg stage produced larger clutches. Our study suggests that females minimize increases in DEE during egg production through behavioral energy reallocation (reduced locomotor activity) but that individuals differ in their use of this strategy, which, in turn, is related to the absolute level of reproductive investment. This suggests a very complex, individually variable system of energy management to meet the demands of egg production.     

Calculating resource restoration for an oil discharge in Lake Barre,Louisiana, USA

Under the United States Oil Pollution Act of 1990, natural resource trustees are charged with assessing natural resource impacts due to an oil spill and determining the type and amount of natural resource restoration that will compensate the public for the impacts. Habitat equivalency analysis is a technique through which the impacts due to the spill and the benefits of restoration are quantified; both are quantified as habitat resources and associated ecological services. The goal of the analysis is to determine the amount of restoration such that the services lost are offset by services provided by restoration. In this paper, we first describe the habitat equivalency analysis framework. We then present an oil spill case from coastal Louisiana, USA, where the framework was applied to quantify resource impacts and determine the scale of restoration. In the Louisiana case, the trustees assessed impacts for oiled salt marsh and direct mortality to finfish, shellfish, and birds. The restoration project required planting salt-marsh vegetation in dredge material that was deposited on a barrier island. Using the habitat equivalency analysis framework, it was determined that 7.5 ha of the dredge platform should be planted as salt marsh. The planted hectares will benefit another 15.9 ha through vegetative spreading resulting in a total of 23.4 ha that will be enhanced or restored as compensation for the natural resource impacts.     

Corporate environmental management study shows shift from compliance to strategy

The Abt study of forty-one mostly Fortune 200 nonservice firms forms a new picture of environmental management. We present data indicating that environmental management is becoming central to corporate strategy and is being managed as an arena of competition rather than as a compliance-driven function. We look at environmental management's new role through four lenses: its relationship to strategic planning; its evolving management structures that show environment increasingly integrated into the main functions of the business; innovation in corporate environmental investments reflecting new drivers beyond compliance; and new management systems and measures of firm-wide performance that demonstrate that environment is being seen increasingly as an arena of competitive concern. We argue that much of the change is driven by three realities. First, as customers integrate environmental values into their conceptions of product quality, they are buying more products with identifiably environmental attributes. This change translates environmental management, historically a cost center, into a potential source of sales revenue, a change which cannot be underestimated. Second, recent life-threatening damage to the global ecosystem and atmosphere reframes environmental management. This moves firms toward a systemic and global approach matched to the globalization of competitive and market concerns, and it places environmental management in the strategic sphere. And third, pollution prevention in its cross-fertilization with total quality management is driving firms to focus on managing environment as an integral part of product management, and is helping them to reassess environmental performance as a contributor to productivity and innovation.
