Introduction Until the late 1980s, the mountainous regions of northern Thailand and northern Vietnam were largely cut off from the rapid economic develop- ment in the urban centers such as Bangkok, Chiang Mai and Hanoi, and from the dynamics of the ‘gree…  相似文献

This study examines the degree to which knowledge of traditional plant medicine is gendered among communities settled near Chapada Diamantina National Park in eastern Bahia state, northeast Brazil. Employing a quantitative analysis of a sample plant pharmacopoeia, I focus on the relationship between gender, age and the socioeconomic impacts of globalization in this tropical region. Results indicate that women are more familiar with both the field identities and the medicinal values of the local flora than are men. This division is pronounced among older participants (30–80 years) who represent a reservoir of medicinal plant knowledge that is in danger of disappearing. I suggest that this heightened understanding among women is due to historical gender divisions of space and labour; the inherently high potential for medicinal plant identification and collection in anthropogenic habitats; and the role of women as primary healthcare givers for the family.  相似文献

Small-scale farmers' experimental innovations have not generally been considered for on-farm research trials as those in the traditional sector have been perceived as recipients, rather than originators, of technical knowledge and sustainable and viable practices. Yet there is abundant evidence throughout the tropics that small-scale farmers are adaptive and experimental problem solvers, and experts at devising innovative survival strategies. While literature on the topic is rich with accounts from Africa, Asia and Latin America, there is a general dearth of examples from the Caribbean. This paper highlights some examples of farm- and village-level problem solving and survival practices among small-scale domestic food producers in the challenging agroecological environment of Jamaica.  相似文献

This paper introduces into the literature the concept of tactile space. In tactile space, forms of representational and non-representational knowledge are exchanged, resulting in the decentering of the subject/objective dichotomy as well as the senses. In doing this, tactile space helps to instill within individuals a greater sense of relationality with others and the environment, which leads to long lasting attitudinal and behavioral changes (versus the superficial changes provided by, say, financial dis/incentives). To help clarify the concept, two different cases are examined. The first example looks briefly at the Sunnyside Environmental School, located in Portland, Oregon (US). The purpose of this first case is to provide some real world flesh to the concept of tactile space. A more detailed conceptual discussion of tactile space takes place in the following section. Here, attention focuses on an in depth study of two cases of community supported agriculture in Iowa (US). The paper concludes by reflecting upon the challenges and opportunities that lie ahead as we further develop our understanding of tactile space and the relations, sensations, and non-representational knowledges it helps to bring forth.  相似文献

对城市水环境实行“红黄绿”分区整治规划,目的在于综合考虑各水层水质水量开采现状、污染程度、工业布局、农业灌溉城市发展规划及水源地保护目标等因素,突出主要矛盾,分期分区整治,使之既符合经济技术约束原则,又强化了目标管理。该方法现代化城市的水环境保护与治理具有较强的可操作性和实际意义。  相似文献

1 The Concept: About Knowledge EconomyIn general terms, all kinds of productions have knowledge with them, either western or eastern, past or present. In production process, people use knowledge to choose suitable materials, to develop processing technologies, fashion and styles to meet the needs of customers and, after all, to make profits (or sometimes to make for "public good"). In order to cut the cost to the possibly lowest level, people also use knowledge to choose suitable places and,…  相似文献

水库多目标供水调度规则研究   总被引:7,自引:0,他引:7       下载免费PDF全文
已有的水库供水调度规则研究偏重于单一目标供水,对于有着不同优先级和保证率的多个供水目标的研究不足.设计了一种水库多目标供水的调度规则,该规则能分别处理不同的供水目标,保证各项用水不发生深度破坏,在此基础上寻求累积缺水最小的调度目标.一种混合模拟和遗传算法的模型被用来对该规则的参数进行优化,在搜索规则最优参数组合的过程中遗传算法显示出很好的优化性能.实例研究检验了提出的供水调度规则的合理性.  相似文献
