摘要

技术性干旱是由于缺乏灌溉技术和水管理系统不完善造成的。在此,我们介绍并分析了对孟加拉国农民进行的一项大型调查的结果,旨在揭示他们对技术性干旱管理的经验、态度、因素和挑战。此外,我们还以孟加拉国北孟加拉省为例,分析了水源的影响和灌溉发展对缓解技术干旱的作用。为了探索技术干旱的性质和特点,我们使用了研究地区的定性和定量数据。我们使用主成分分析法(PCA),利用实地数据找出了技术干旱的基本维度和因子载荷。此外,我们还比较了社会人口特征、水源特征和技术干旱感知之间的关系和关联。PCA 结果表明,在技术干旱的 31 个因子中,有 7 个基本维度(挑战)与河水管理、灌溉技术、社会经济条件、土地利用以及电力和燃料供应有关。在案例研究地区,人口众多、缺乏现代灌溉技术、上游管理问题、系统效率低下、电力连接、减载以及恶劣的社会经济条件阻碍了人们获得急需的水。我们还发现,农民的社会人口特征和水源特征与技术干旱感知之间存在重要关系。尽管近年来灌溉技术的使用越来越多,水资源管理也得到了改善,但必须强调的是,如果这一趋势继续下去,未来可能会面临更多挑战。

Living with technological drought: Experience of smallholding farmers of Bangladesh

Technological drought is caused by a lack of irrigation technology and a poor water management system. Here we present and analyse the results of a large survey of farmers in Bangladesh, designed to reveal their experience of and attitudes to, as well as factors and challenges of technological drought management. Also, we analysed the impact of water sources and the role of irrigation development to mitigate the technological drought taking North Bengal of Bangladesh as a case study. To explore the nature and characteristics of technological drought, we have used both qualitative and quantitative data from the study area. We used Principal Component Analysis (PCA) to find out the underlying dimensions and factor loadings of the technological drought using the field data. Moreover, we compared the relations and associations between socio-demographic, water source characteristics and technological drought perceptions. PCA results indicated seven underlying dimensions (challenges) out of thirty-one factors of technological drought related to river water management, irrigation technology, socio-economic conditions, land use, and electricity and fuel supply. The high population, lack of modern irrigation technology, upstream management problems, inefficiencies in the system, electricity connections, load shedding, and poor socio-economic conditions prevent people from getting the water they desperately need in the case study area. We also found a significant relationship between farmers’ socio-demographic and water source characteristics with technological drought perceptions. Although there has been increasing use of irrigation technology and improved water resource management in recent years, it is essential to highlight that there will likely be more challenges in the future if this trend continues.

期刊介绍: Environmental Development provides a future oriented, pro-active, authoritative source of information and learning for researchers, postgraduate students, policymakers, and managers, and bridges the gap between fundamental research and the application in management and policy practices. It stimulates the exchange and coupling of traditional scientific knowledge on the environment, with the experiential knowledge among decision makers and other stakeholders and also connects natural sciences and social and behavioral sciences. Environmental Development includes and promotes scientific work from the non-western world, and also strengthens the collaboration between the developed and developing world. Further it links environmental research to broader issues of economic and social-cultural developments, and is intended to shorten the delays between research and publication, while ensuring thorough peer review. Environmental Development also creates a forum for transnational communication, discussion and global action. Environmental Development is open to a broad range of disciplines and authors. The journal welcomes, in particular, contributions from a younger generation of researchers, and papers expanding the frontiers of environmental sciences, pointing at new directions and innovative answers. All submissions to Environmental Development are reviewed using the general criteria of quality, originality, precision, importance of topic and insights, clarity of exposition, which are in keeping with the journal''s aims and scope.
