Revolution or inch-by-inch? Campaign approaches on climate change by environmental groups

Climate change is a significant environmental, social and environmental problem that has been identified by scientists in consensus internationally. The Australian Government’s response is considered by environmental non-government organisations (NGOs) to be inadequate. NGOs are ‘change agents’ of society, and in this role they are agitating to influence political decision-making on climate change response. This paper outlines the campaign strategies being used by Australian NGOs to attract public and political attention to the issue of climate change. Using seven NGOs as case studies, the archival materials of these organisations were accessed and analysed. Current academic and other literature also was used to reflect on their effectiveness. Four campaign themes and, within these, fifteen activities were identified. The results indicate that the notion of whether NGOs are undertaking an ‘revolutionary’ or ‘incremental’ approach, or any other narrow strategic approach put forward by various scholars is too simple for analysing campaigns: none of the NGOs appear to intentionally favour one type of strategy. The question raised by this finding is whether the NGOs’ current ‘multi-strategic’ approach is effective. This research contributes to filling the information gap with regard to NGO campaign strategies on environmental issues, and highlights the need for further research.

连续流好氧颗粒污泥强化策略研究进展

好氧颗粒污泥 (aerobic granular sludge,AGS) 因其具有污泥浓度高、结构致密、生物活性强、沉降性能好、同步脱氮除磷和抗负荷能力强等优势,被认为是一种极具发展潜力的新型污水生物处理技术,有望在水污染控制领域得到推广应用。与传统的序批式反应器 (sequencing batch reactor,SBR) 相比,连续流好氧颗粒污泥反应器 (continuous flow reactor- aerobic granular sludge,CFR-AGS) 具有连续处理、运行简便、设备利用率高等优点,可满足大部分污水厂的水处理需求,故更具有研究与应用价值。通过对文献的整理和归纳,调研了国内外AGS的研究现状,分析了连续流工艺下污泥颗粒化的难点和局限性,提出了在连续流工艺条件下促进污泥颗粒化的策略,并展望了CFR-AGS未来的研究方向和发展趋势。     

Evaluating efforts to build sustainable WEEE reverse logistics network design: comparison of regulatory and non-regulatory approaches

Many developing countries such as Turkey are still making an effort on building an infrastructure for waste of electrical and electronic equipment (WEEE) reverse logistic network design (RLND) processes. It is obvious that policies/laws/regulations related to WEEE management provide a sustainable framework for implementation in the RLND. The question is here: Does the implementation of WEEE directives make sense in terms of reducing the total cost of the network in the long term? This study aims to compare regulatory and non-regulatory situations of WEEE RLND in developing countries by formulating two models named as ‘regulatory’ and ‘non-regulatory’. Model 1 is considered as sustainable with economic, environmental and social goals, and the quotas imposed by the environmental directive are taken into consideration as the data of product return amount. In Model 2, only economic goal is considered, and product return amount is forecasted using Artificial Neural Network (ANN). A case study is conducted in a recycling company in order to evaluate performance of the proposed models. This study contributes to the relevant literature by (1) comparing the regulatory and non-regulatory situations RL models explicitly and (2) proposing ANN model to forecast EEE product return or WEEE quantity for non-regulatory situation.     

HIV risk and prevention in emergency-affected populations: a review

While basic guidelines on HIV prevention in emergencies have been available for several years, international agencies involved in the provision of health services have not placed sufficient priority on the prevention of the human immune deficiency virus (HIV) and other sexually transmitted infections (STIs) in complex emergencies. This paper reviews the factors that may increase the risk of HIV transmission in populations affected by complex emergencies and outlines recommendations for research and programmes. Research into the most appropriate methods of carrying out HIV surveillance and interventions in these settings is needed. In the post-emergency phase programmes need to be far more extensive than those offered under the Minimal Initial Services Package (MISP). While the potential for stigmatization represents an important constraint, there is a need to prioritize HIV/STI interventions in order to prevent HIV transmission in emergency-affected populations themselves, as well as to contribute to regional control of the epidemic.     

新藏公路(新疆段)沿线道路病害及成因初析

新藏公路新疆段横跨塔里木盆地与昆仑山两大地貌单元，沿线泥石流、滑坡、水毁、崩塌、坍塌、碎落、雪害、涎流冰、翻浆和多年冻土等道路病害类型多样，发生频繁，不时断道阻车，严重影响着新藏公路的通行。该段沿线地质构造错综复杂，新构造运动和地震活动强烈，地形起伏大，地貌类型多样，气候条件多变，冰川作用强烈，以及人为不合理的建设活动和现有道路设计标准低、承灾能力差等，促进了各类道路病害的形成和发展。随着全球气候变暖、太阳活动和地震活动的加强，道路病害将进人新的活跃期，防灾形势十分严峻。     

Modeling Opportunity Costs of Conservation in Transitional Landscapes

Abstract:  Conservation scientists recognize the urgency of incorporating opportunity costs into conservation planning. Despite this, applications to date have been limited, perhaps partly because of the difficulty in determining costs in regions with limited data on land prices and ownership. We present methods for estimating opportunity costs of land preservation in landscapes or ecoregions that are a changing mix of agriculture and natural habitat. Our approach derives from the literature on estimating land values as opportunity costs of alternate land uses and takes advantage of general availability of necessary data, even in relatively data-poor regions. The methods integrate probabilities of habitat conversion with region-wide estimates of economic benefits from agricultural land uses and estimate land values with a discount rate to convert annual values into net present values. We applied our method in a landscape undergoing agricultural conversion in Paraguay. Our model of opportunity costs predicted an independent data set of land values and was consistent with implicit discount rates of 15–25%. Model-generated land values were strongly correlated with actual land values even after correcting for the effect of property size and proportion of property that was forested. We used the model to produce a map of opportunity costs and to estimate the costs of conserving forest within two proposed corridors in the landscape. This method can be applied to conservation planning in situations where natural habitat is currently being converted to market-oriented land uses. Incorporating not only biological attributes but also socioeconomic data can help in the design of efficient networks of protected areas that represent biodiversity at minimum costs.     

我国珍稀濒危物种适应气候变化的对策探讨

基于气候变化下部分珍稀濒危物种脆弱性分析,初步提出了适应对策,探讨了部分物种适应措施。气候变化下,珍稀濒危物种脆弱性表现在物种分布范围减少、破碎化和失去原分布范围、丰富度下降、种群数量减少、物种灭绝、栖息地退化或消失等。珍稀濒危物种适应气候变化需要分析物种自然适应机制,加强就地保护,增加种群数量,开展迁地和遗传保护,减少其它干扰,保护和恢复栖息地,建立自然保护区适应对策等。每个物种需要分析目前濒危程度和气候变化下的脆弱性来提出适应对策。
