RURAL DEVELOPMENT IN EL HATILLO, NICARAGUA: GENDER, NEOLIBERALISM AND ENVIRONMENTAL RISK

El Hatillo is a rural community in the Sébaco valley in Nicaragua, which suffers from an eroding resource base, high levels of poverty and malnutrition, and a high susceptibility to hazards. Structural adjustment policies have been devastating for small and subsistence farmers and have increased the level of economic, social and environmental marginalisation in rural Nicaragua. This paper explores initiatives to promote sustainable development in Nicaragua in the context of structural adjustment and environmental degradation. Drawing on qualitative research conducted in El Hatillo, it outlines the ways in which women in this community are attempting to address the multiple challenges of rural poverty and environmental risk and considers the potential of these strategies for gender equality.     

博斯腾湖向塔里木河输水风险分析方法

为了拯救塔里木河下游生态环境，塔里木河流域管理局根据博斯腾湖从1999年到2003年处于丰水期，湖泊处于高水位的有利时机，从2000年5月到2003年6月实施5次向塔里木河下游生态应急输水，结束塔里木河下游300多km河道近30年的断流历史。现在的问题是“博斯腾湖向塔里木河生态输水能否持续?”，“保证可持续输水的风险有多大?”本文以解决此问题为实例，介绍一般水库调节计算和水库特征水位确定方法；主要探讨水库(湖泊)向下游输水可持续性风险分析问题，提出的方法称为“水库输水可持续性风险计算时历试算法”，简称为“试算法”(T＆E方法)；并将此方法应用于实例中，计算博斯腾湖向塔里木河下游输水的可持续风险。     

The Victorian Bushfires of 2002–03 and the Politics of Blame: a Discourse Analysis

This paper identifies contrasting environmental discourses on bushfire from the public debate that followed the Victorian fires of 2002–03. Submissions to the inquiry into the 2002–03 Victorian bushfires provide a particularly rich source of documentation. It is argued that environmental events such as bushfire only become political issues, or problems, when they are constituted as such through environmental discourse. Through the analysis, three contrasting discourses on bushfire are identified—here labelled the ‘conservationist’, ‘ruralist’ and ‘wise use’ discourses. In examining how different ‘constructions’ of bushfire have led to conflict, each discourse is shown to consist of a range of actors who draw on shared storylines. Having established a better understanding of the different attitudes, beliefs, interests and values that underpin debates about bushfire, the paper concludes with a brief discussion of the prospects for compromise among the discourses and the potential for improved land and fire management outcomes.     

Paleo-earthquake studies on the eastern section of the Kunlun fault

Introduction East Kunlun active fault is one of the largest sinistral slip fault zones in northern Tibetan Pla-teau. The fault tails primarily after the ancient eastern Kunlun suture zone, which was reactivatedby the northward subduction of the Indian plate beneath the Eurasian plate. The western end of thefault starts near the western flank of the Buxedaban peak in Qinghai Province. The fault then ex-tends eastwards through the Kusai Lake, Xidatan, Dongdatan, Alag Lake, Tuosuo Lak…

‘Committing to Place’ at the Local Scale: the potential of youth education programs for promoting community participation in regional natural resource management

Emerging approaches to environmental governance require a greater level of community participation than did previous approaches in which these responsibilities largely rested with government agencies. There is consequently a need for increased engagement with NRM among a broad community sector. This paper examines initiatives by two prominent government agencies, the Murray–Darling Basin Commission (MDBC) and the National Museum of Australia (NMA), to engage school children from regional communities using education programs that focus on place and environmental health. We focus on the MDBC's International Riverhealth Conference held in Mildura in 2003 and the associated Murray–Darling Basin TalkBack Classroom sponsored by the NMA and the Parliamentary Education Office (PEO). We explore how key themes of local scale, place-based identities, youth voice and critical engagement are developed in these programs and consider how they relate to the environmental agency of children. We then reflect on the potential for the kinds of environmental agency promoted through these programs to help build the capacity of local communities to progress larger goals of environmental restoration and sustainability in the Murray–Darling Basin. The evaluation research reported here forms part of the Committing to Place research project, an Australian Research Council Linkage grant involving the University of Tasmania, the National Museum of Australia and the Murray–Darling Basin Commission.
