ABSTRACT The signing of Colombia’s peace agreement in 2016 signaled the end of a decades-long war between the government and the FARC (Las Fuerzas Armadas Revolucionarias de Colombia), but also an emerging assault against the country’s forests. This article aims to understand the interactions between forests and peace. In doing so, it traces landscape transformations of deforestation and possibilities for making landscapes livable in the midst of disturbance. Drawing on field research, including interviews and participant observation carried out in Colombia from 2016 to 2018, it reveals how deforestation is driven by ongoing colonization and land grabbing, mostly dedicated to extensive cattle ranching, coca cultivation, and campesinos’ transition to ‘licit’ agricultural alternatives. The article also shows how emerging coordination among farmers and forests following forest disturbance contributes to an interpretation of peace in which forests are integral. The article concludes with a call to incorporate forests in the construction of peace. 相似文献

污水土地处理水旱轮作条件下碳素在土层中迁移特征的模拟实验 总被引:5,自引:0,他引:5
为了解污水土地处理过程 中不同土壤类型土壤溶液P含量和迁移特征,在一种特殊2的大型人工模拟土层和地下水实验装置中进行试验。研究结果表明:水田条件下1.5m~0.5m土壤溶液P含量极低(≤0.02mg/L),但在旱地条件下,P含量上升至0.045mg/L~0.628mg/L,P素随入渗污水向下迁移距离可达1.1m。在低水力负荷率和较长停留时间的运行条件下,1.3m以下土壤溶液和地下水的P含量处于安全 相似文献

SUMMARY Xishuangbanna in southwest China is a tropical and subtropical region with extraordinary traditional cultures and attractive landscapes. Rubber cultivation is a key production source undergoing rapid growth. It contributes substantially to improvement of the local economic situation and partially replaces traditional slash-and-burn agriculture in the uplands, but it also results in biodiversity loss and environmental degradation and disturbs the peaceful life of the indigenous people. We discuss the traditional ecological knowledge (TEK) preserved in daily practices and the present types of rubber plantations and suggest the application of TEK, in particular, the indigenous land-use experience to rubber cultivation, in order to promote sustainability in local economic development and ecological well-being. 相似文献

In this study, we investigate whether traditional swidden agriculture on nutrient-poor tropical soils can sustainably support
a growing indigenous population within Manu National Park, Peru. Based on interviews with 50 Matsigenka farmers, as well as
GPS mapping and field visits, we established the location and size of all 124 swidden gardens cultivated in 2000 and 2001.
Using a GIS-based soil map of Manu Park, we identify the total extent of potential arable land (1) throughout the park zones
currently available for Matsigenka habitation, and (2) within the vicinity of the two study communities. Taking into account
current per capita garden size, cultivation and fallow practices, we calculate the maximum human carrying capacity of swidden
agriculture for (1) all available park zones and (2) the immediate vicinity of the two current communities. Even given the
second, highly limited scenario, the sustainable human carrying capacity is estimated to be 2,138 individuals, which is far
higher than the current population of about 420 people. Thus, arable land does not appear to be a limiting factor for the
growth of the indigenous population in Manu Park at the current time. Other possible limiting factors for population growth
are identified and discussed. We conclude that a conservation policy of population stabilization around the current settlements
is viable in that it will not result in reduced resource availability over the next few decades, and that the challenge is
to identify and mitigate the forces causing population fissioning and spread.

昆明市规模化畜禽养殖场污染现状及控制对策 总被引:1,自引:0,他引:1
对昆明市畜禽养殖污染现状调查显示,2002年规模化畜禽养殖场产生粪尿207290t,大部分被作为农家肥处理掉,平均使用率为85%,但几乎未经过无害化处理,对周围区域水体及湖泊造成严重污染.政府应对畜禽养殖业进行宏观监挖,加大环境管理力度,加强畜禽污水监测排放,并进行减量化治理,无害化处理,综合利用,循环发展,实现生态养殖. 相似文献
