Status,stigma and energy practices in the home

Domestic energy practices are a topical policy issue, with implications for climate change, energy security and fuel poverty. Accordingly, a growing body of literature examines ways of promoting energy conservation and generation by individuals. However, there has been relatively little discussion of how status and stigma are implicated in these practices, and may act as facilitators or barriers to “behaviour change”. To help address this gap, this article draws both on existing literature and a new UK-based study of people who are attempting to live sustainable lives, to provide insights into how domestic energy practices may be status-enhancing or stigmatising, and how these risks and opportunities can be managed. While energy practices are often understood as “inconspicuous”, it is argued here that in some circumstances individuals may actively manage the visibility of their energy practices. The discussion considers these findings with regard to social power relations, and identifies issues warranting further exploration within the emerging research agenda on energy and equity.     

Shaped by race: why “race” still matters in the challenges facing biodiversity conservation in Africa

This article uses experiences from South Africa to argue that, despite progress made in making biodiversity conservation compatible with social, political and economic changes, progress could still be limited by reluctance of social actors to acknowledge and engage with the issue of race. The article argues that acknowledging the history of conservation in Africa, including close ties to racially charged colonialism, could be a positive impetus in the transformation of conservation to make it more socially, economically and politically justifiable.     

Monitoring and environmental modeling of earthwork impacts: A road construction case study

This study presents the contributions of materials, earth engineering machines and construction techniques to potential environmental impacts from the main items of typical road earthworks. To achieve this goal, the overall activity at a 1.9-km long French earthworks project site for a heavily trafficked highway was surveyed during its 2007–2009 construction period. Using data collected and a numerical model of road life cycle assessment (LCA), i.e. ECORCE, six indicators could be evaluated, namely: energy consumption, global warming potential, acidification, eutrophication, photochemical ozone creation, and human chronic toxicity. When available, several life cycle inventories were implemented in order to appraise indicator sensitivity with respect to the considered panel of pollutants. Results also allowed estimating from an LCA point of view: (i) the conservation of both aggregates and soil as induced by quicklime treatment and (ii) the duration necessary for projected traffic levels to offset the potential environmental impacts of the earthworks stage.

Watershed development in India. 1. Biophysical and societal impacts

This paper recommends a revision of watershed development policy in India in relation to the planning of development interventions involving agricultural intensification and rainwater harvesting following biophysical and societal impact studies carried out on two watershed development projects in Karnataka. A need for changes in policy has arisen in response to progressive catchments closure at the basin level and declining volumes of water flowing into village level reservoirs (known locally as tanks). Flow reductions have occurred largely as a result of increased agricultural intensification over the past 10–15 years. Field levelling, field bund construction, soil water conservation measures, farm ponds, the increase in areas under horticulture and forestry and the increased abstraction and use of groundwater for irrigation are all contributing factors to reduced flows. Planning methodologies and approaches, which may have been appropriate 20 years ago for planning water harvesting within watershed development projects, are no longer appropriate today. New planning approaches are required which (1) take account of these changed flow conditions and (2) are also able to take account of externalities, which occur when actions of some affect the livelihoods of others who have no control or influence over such activities and which (3) contribute to the maintenance of agreed minimum downstream flows for environmental and other purposes.

Runoff variation affected by precipitation change and human activity in Hailiutu River basin,China

For recent years, runoff generation and hydrological processes in Hailiutu River basin have been greatly changed by climate change and human activity, especially water and soil conservation construction. In this study, the trends in precipitation, evapotranspiration (ET) and river runoff as well as the effects of precipitation change and human activity on runoff variation have been studied. The results showed that during 1960–2000, annual precipitation and river runoff, monthly precipitation and ET in September and October as well as monthly runoff in all months showed a significant decrease. In addition, peak flow and base flow had a large decrease. Under the joint influence of precipitation change and human activity, the mean annual runoff decreased by 35 million m³ from the baseline period (1960–1985) to the change period (1986–2000), which accounted for 60.9% and 39.1% of the total runoff decrease, respectively. Precipitation change played a primary role in the decrease of annual runoff whereas human activity, particularly water and soil conservation construction, also had remarkable impacts on runoff variation.     

Cross-Platform Framing and Cross-Cultural Adaptation: Examining Elephant Conservation in Thailand

This case study investigates cross-platform framing process and framing alignment strategies of the world famous elephant conservation NGO. It examines how the intercultural adaptation facilitates the frame transformation against entrenched domesticated elephant traditions in Thailand. Besides web observation, this study conducted two field trips to interview the NGO staff and conservation experts, and observed human–elephant interaction. Enhancing the understanding of ecotourism, this study expands the framing theory by incorporating cross-platform and cross-cultural adaptation factors and provides insights of an effective Asian ecotourism model which transcends cultural differences and overcomes resistance by disseminating culturally sensitive and integrated framing strategies through various communication channels.     

Systematic Contradiction Between Heritage Conservation and Tourism Development: Cleaning the Temple and Cemetery of Confucius and the Kong Family Mansion in Qufu

Abstract

In recent years, with the rapid development of the tourist industry, world heritage sites become more and more popular among tourists from home and abroad. Therefore, heritage tourism has become a new hotspot. However, while world heritage sites are making obvious economic benefit from tourism, they also bring various problems and contradictions, of which the most troublesome one is the contradiction between heritage conservation and tourism development. To discuss and analyze the root and the essence of the above contradiction and find a way to bring about harmony between them is an important program faced by our national heritage management practice and academic research. Based on the case of cleaning the Temple and Cemetery of Confucius and the Kong Family Mansion in Qufu, this paper analyzes the reasons why our national world cultural heritage sites bring about the above contradiction in the process of tourism development and points out that the improper system and stakeholders' benefit imbroglio are respectively the root and the essence of the contraction. Then, it also puts forward corresponding solutions.

保护性耕作对玉米田土壤中除草剂残留的影响

保护性耕作能够显著提高土壤有机质,改善土壤质量,但是关于保护性耕作如何影响农药等污染物在土壤中残留的研究却较为匮乏,而土壤污染又与粮食安全息息相关.因此,选择7个实验地点,针对传统耕作与保护性耕作两种耕作方式下土壤中3种除草剂(乙草胺、阿特拉津和二甲四氯钠)残留特征进行了分析.结果表明,保护性耕作显著影响土壤的总有机碳含量、土壤含水率和土壤团聚体平均粒径等性质[使(2.1±0.1)%、(19.1±1.2)%和(82.2±3.0)μm分别增加至(2.9±0.3)%、(22.3±1.5)%和(97.2±4.2)μm].研究进一步发现,保护性耕作对不同除草剂在土壤中残留的影响存在差异性.例如,保护性耕作通过影响土壤总有机碳含量显著增加东丰试验田土壤中阿特拉津的含量[使(3.8±0.3)ng·g^-1增加至(17.7±3.0)ng·g^-1],通过影响土壤团聚体平均粒径显著降低德惠试验田土壤中乙草胺的含量[使(50.6±10.3)ng·g^-1降低至(9.2±2.5)ng·g^-1].然而,由于不同土壤性质对土壤中...
