Intersections of gender and water: comparative approaches to everyday gendered negotiations of water access in underserved areas of Accra,Ghana and Cape Town,South Africa

A large and growing body of literature suggests that women and men often have differentiated relationships to water access, uses, knowledges, governance, and experiences. From a feminist political ecology perspective, these relationships can be mediated by gendered labour practices (within the household, at the community level, or within the workplace), socio-cultural expectations (e.g. related to notions of masculinity and femininity), as well as intersectional differences (e.g. race, income, and so forth). While these relationships are complex, multiple, and vary by context, it is frequently argued that due to responsibility for domestic provision or other pathways, women may be particularly affected if water quality or access is compromised. This paper reports on a statistical evaluation of a 478 household survey conducted in underserved areas of Accra, Ghana and Cape Town, South Africa in early 2012. Interrogating our survey results in the light of the ideas of gender differentiated access, uses, knowledges, governance, and experiences of water, we open up considerations related to the context of each of our study sites, and also invite possible revisions and new directions for these debates. In particular, we are interested in the instances where differences among male and female respondents were less pronounced than expected. Highlighting these unexpected results we find it helpful to draw attention to methods – in particular we argue that a binary male–female approach is not that meaningful for the analysis, and instead, gender analysis requires some attention to intersectional differences (e.g. homeownership, employment, or age). We also make the case for the importance of combining qualitative and quantitative work to understand these relationships, as well as opening up what might be learned by more adequately exploring the resonances and tensions between these approaches.

Differentiation between drug use and environmental contamination when testing for drugs in hair

The differentiation between systemic exposure and external contamination for certain drug groups has been frequently referred to as one of the limitations of in drug testing in hair. When hair samples are used, three steps are usually employed in order to minimise the possibility of external contamination causing a misinterpretation. The first consists of decontaminating hair samples by washing the hair before analysis, the second is the detection of the relevant metabolites in the hair samples and the third is the use of cut-off levels. Difficulty in the interpretation arises when metabolites are not detected either due to external contamination of the hair or low doses of the drugs used. A wash protocol needs to be practical and ideally remove any drug deposited on the external portion of the hair.     

At Boiling Point: Like Water for Chocolate and the Boundaries of Mexican Identity

Abstract — This article explores the mechanisms of Mexican identity as they are constructed in Alfonso Arau's film Como agua para chocolate (1991) (Like Water for Chocolate). In re-designing the characters of Laura Esquivel's novel, Arau produces a range of filmic stereotypes drawn from both the Hollywood and the Mexican traditions of film-making. Through the careful manipulation of filmic devices such as editing, framing and close-ups, many of the features of Mexican otherness perpetuated by Hollywood throughout the twentieth century are inscribed. I apply the metaphor of boiling, derived from the film's title, to examine certain key concepts of cinematic 'mexicanness' including the tropes of 'revolution', 'border', 'race' and 'sex'. Crucial to this argument is a consideration of the contemporary political climate in which Like Water for Chocolate was both produced and released. In Mexico, it was released halfway through the sexenio (six-year period of rule) of President Carlos Salinas de Gortari's rule and is clearly one of the most succesful cultural products (and exports) of his government's now infamous rule. In the United States, the climate of anti-immigrant attitudes in 1992 and 1993 and the corresponding political tension provokes new readings of certain stereotypical images of Mexicans and mexicanness. It is the tension that is produced by the collision between these two contexts — cultural, political and ethnic — that forms the principal focus of discussion in this article.     

地缘性介入与制度性嵌构：美国亚太区域水安全外交战略

根据地缘利益诉求(攻势/守势)与跨国流域水治理程度(工具性/制度性)两个指标,可以将"水安全外交"界定为国家以及相关行为体围绕跨境水资源安全问题展开的博弈行为。水安全外交包括冲突预防型、霸权引导型、水互动冷漠型和治理后现代型四种类型。作为霸权引导型的美国水安全外交战略,其核心是通过水的全球治理来巩固其全球霸权地位,主要表现在两个方面:一是通过大国的地缘性介入,保障其水外交的战略利益;二是通过对区域水治理体系的制度性嵌置和重构,保持其水外交的合法性和有效性。美国通过水外交的四条路径(联盟和议题联系方式、同水外交大国的协调方式、国际组织议题嵌入、网络化伙伴关系)推进水安全外交政策和安全战略的制定。在其水外交进程中,国内外的动因机制发挥了重要作用。美国通过水安全外交拓展自身在亚太的地缘利益诉求,推行美国价值观的水治理原则和规范,嵌构以美国为核心的水安全治理体系,遏制地区大国(特别是中国)的水话语权,以最终实现美国在区域水—能源—粮食纽带安全中的战略优势平衡。     

环首都区域水资源协调发展现状分析与对策

环首都水源涵养区是中国首都乃至全国的重要生态屏障,对维护首都和华北地区生态安全极为重要.由于缺乏长效保障机制,环北京周边地区生态环境严重退化,上游地区自产水量和出境水量均大幅度减少.统计分析表明,从2000到2011年,年均自产水量和出境水量分别减少了25％和64％.针对这种情况,该文分析了环首都水源涵养区水资源协调发展已具备的优势、条件以及存在的问题.在此基础上,从机构建设、专项基金建立、特殊财政支持和统一规划制定等5个方面提出了环首都水源涵养区水资源协调发展对策与建议.     

Decentralisation and Supply Efficiency: The case of Rural Water Supply in Central India

Demand for decentralisation of provision of public services is gaining ground in developing countries. Also, the policy advice to decentralise given by international agencies to the developing countries is turning into pressure. However, the benefits of decentralisation are not as obvious as the standard theory of fiscal federalism predicts. This article examines the effect of decentralisation of provision of drinking water in central India. The efficiency of water utilities under the control of the state government and those under the local governments is compared in terms of expense and asset utilisation. It is found that the decentralised provision of water supply is less efficient. The possible reasons for this counter intuitive result are analysed.     

Changing Hydropolitical Relations in the Nile Basin: A Protracted Transition

A new hydro-political order is emerging in the Nile Basin. Upstream riparian states have improved their bargaining power vis-à-vis downstream countries by adopting a common position in the negotiations over a new framework agreement to govern the utilisation of the Nile waters. Some upstream riparians have unilaterally constructed hydraulic projects that threaten Egypt’s hegemonic position in the basin, the most notable of which is the Grand Ethiopian Renaissance Dam (GERD). Whether these developments will lead to a more equitable utilisation of water resources and a more cooperative order will depend on the policies of the riparian states, especially in the Eastern Nile. Respect of the Declaration of Principles on the GERD signed between Egypt, Ethiopia and Sudan could help build trust between the three countries after years of tensions around the project. Beyond that, a basin-wide plan for the utilisation of water resources would not only maximise the benefits from the river and address the common challenges facing the basin, but also reduce the political costs of tensions on future projects.     

Citizens,consumers, workers,and activists: civil society during and after water privatization struggles

Water privatization battles and their aftermath in seven Latin American, African, and Asian countries feature diverse and often complementary forms of action by unions, popular movements, neighbourhood associations, and non-governmental organizations (NGOs). NGOs cooperate with popular movements for water rights more than the literature would suggest, and after mobilizations against privatization, activists have had some success maintaining pressure for better service to poor neighbourhoods through advocacy and local self-provision arrangements. Public employees’ unions play important roles in water policy coalitions, often practising a distinctive form of social movement unionism. These experiences argue for a more flexible understanding of categories and organizational forms in civil society.
