一种确定林业发展项目的有效工具(英文)

在云南省绿春县的有些村庄,由砍柴造成的森林破坏是造成环境退化的主要原因。在黑河流域的上游,不断加剧的水土流失和河床抬升对下游上百万的人们构成威胁。尽管人们对森林破坏和土地的可持续利用、社区可持续发展之间的关系不是不了解,但当生存压力存在的时候就会忽略由此造成的对未来的影响。对于村民来说,他们已经意识到了他们的生存状况,并讨论解决的有效途径,而不是单纯等待外界的援助和干预。问题的关键是如何将这些变化和影响以一种直观和形象的方式向村民解释,并且让包括文盲在内的所有人都能理解。从这方面考虑,图形的东西比文字和数字分析更有优势。本文采用MIGIS(移动交互式地理信息系统的英文缩写,它包括两部分的内容,即PLA-参与式学习和行动和GIS-地理信息系统)在云南省绿春县哈尼族村寨来协助进行村民自发的造林规划。图6表1参16。

MIGIS-an effective tool to negotiate development interventions re-lating to forestry

Deforestation caused by the felling of trees for firewood is a major cause of environmental degradation in some vil-lages in Luchun County, Yunnan Province. This is of particular concern in the headwaters of major rivers such as the Black River where increased runoff, erosion, and sediment yield impact on the millions of persons living downstream. While the links be-tween forest clearance, the ability of the land to sustain production, and the sustainability of communities are understood, the pressures of having to survive today often outweigh consideration of the consequences for tomorrow. The real challenge for these communities is that they recognise their situation and negotiate a practical solution rather than wait the intervention and support. It is essential therefore that the changes which have taken place are documented and their future impact illustrated. This information must then be portrayed in a manner that makes it accessible and comprehensible to all, even to those who are illiterate. For this reason the use of graphics offers considerable merit over textual and numerical analyses. This paper explores the use of MIGIS (an acronym for community based planning which integrates the techniques of PLA and GIS) to facilitate a negotiated, bottom-up approach to afforestation with the Hani farmers of Luchun County, Yunnan in southwest China.
