This paper describes a role playing planning exercise that has been used for training agriculturists, engineers and agricultural economists for more than ten years. It sets out the objectives and key features of the exercise and the experience that has been gained in its use. The exercise has been found to successfully test and integrate subject matter expertise acquired from formal teaching. It also highlights the multiple and often conflicting objectives of irrigation planning, and the need for full evaluation of alternatives and sound technical judgements under conditions of inadequate data and time pressure. The exercise is also successful in developing professional personal skills such as group working, interviewing and presentation, and is recommended as an effective training aid.  相似文献

The reed forests that are the subject of this study are scattered over five thanas of the Sunamganj and Sylhet Districts of the Sylhet Division of Bangladesh. Their total area is 23,590 ha and they have great ecological, economic, commercial and socio-economic importance due to the diversified resources they supply. However, the forests are commonly encroached on by local people who are perceived to be seriously depleting the resource. This paper deals with the socio-economic status of the people residing near these reed forests, and examines their dependency on the resources provided by the reed forests. A socio-economic survey, participatory rural appraisal and interviews were used to obtain baseline data of the reed forest resource and the local communities. The study reveals that the communities in the study region have higher income than other areas of Bangladesh. Most survey respondents have other occupations in addition to farming. The literacy rate is 28.8%. Among the illiterate, 68% engage in collecting reeds. Although the Forest Department has a management plan for sustainable use of the reed forests, encroachers receive backing from political leaders and local elites, so their eviction is difficult. In order to achieve long-term productivity and sustainability from the reed forests, this study recommends a strategy of developing an integrated joint management plan between the Forest Department and the local people.  相似文献

为探索气候变化感知在适应决策过程中的作用机理,本研究以深度访谈数据为基础,基于“感知-适应”分析框架,采用二元Probit模型和泊松回归模型,分析胶州湾地区居民气候变化适应决策和适应选择的影响因素。研究表明,胶州湾地区绝大多数居民已经感知到气候变化,半数以上居民采取了一定的适应措施,大多数居民对适应措施效果的感到满意。居民采取适应措施介于0-4项,平均为1.07项,适应措施的普及率和多样化仍有提升空间。影响胶州湾地区居民气候变化适应决策与适应选择的主要因素存在一定差异性,但“居民对气候变化的感知”不论是对适应决策还是对适应选择的影响都较大,其中又以“对降水变化的感知”和“对气象灾害损失的感知”最为显著。  相似文献

‘Angelys’ is a new brand of pear cultivar, produced and marketed under the trademark license model called “Club variety.” The main aim of this article was to evaluate factors triggering a potential interest in Italian large-scale retail regarding the marketing of ‘Angelys’ and how large-scale retailers would exploit it to enhance their market potential. An explorative analysis approach was applied via in-depth, semi-structured qualitative interviews with major Italian large-scale retail fruit purchase managers. The results show that although sensory properties, handling features, and Italian origin are highly appreciated by professional customers, the need to sell at a premium price might limit the interest of retailers for this new variety. Finally, implications and recommendations for academics and operators are discussed.  相似文献

为客观揭示青崖寨自然保护区村级景观格局动态变化特征,为保护区村域科学管护提供参考案例,本文以保护区实验区内的大会庄村为例,在Agisoft PhotoScan Professional和Fragstats软件支持下,基于三维电子沙盘,通过参与式访谈的方法,研究村民视角下记忆中的1995、2006、2016年大会庄村历史景观格局变化。结果表明:(1)通过对大会庄村3个时期景观类型面积的计算,在1995—2016年期间林地、建筑用地、水域景观类型分别增加8.00、1.79、1.95 hm2;耕地、草地、未利用地景观类型分别减少9.81、0.37、1.56 hm2。(2)在景观水平上,大会庄村景观连接度下降,但整体内部结构连接紧密,破碎化程度逐渐降低,单一性降低,景观多样性得到恢复。(3)驱动因素中自然因素并不是影响研究区景观格局变化的唯一条件,社会经济水平和政策均发挥着重要作用。该研究证明基于三维电子沙盘的参与式访谈对村域历史景观格局的复原有指导作用,可有效解决与村民直接沟通中存在的障碍。  相似文献
