Tree planting in Tigray, Ethiopia: the importance of human disease and water microdams

We examine the decision to plant trees and level of tree planting for two sites, public microdam areas and household agricultural land, and two species groups in Tigray, Ethiopia. Both sites are not perfect substitutes, as they vary with respect to distance from the household and tenure security. The role of permanent pooled water irrigation microdams to tree planting is important but unknown, because water borne diseases, which may influence household income and productivity, are thought to be enhanced by the dams. We find both disease and microdams to be important predictors to tree planting. Disease seems more important in determining whether households plant at all, and less important in the level of planting for those that do plant. For example, disease increases the probability of planting both eucalyptus and other species groups on household-own land, but households suffering from malaria plant higher-cost eucalyptus trees with lower probability at both sites, while planting of other lower-cost species increases at dam sites where other villagers can monitor the trees. We also establish a connection between planting and agricultural residues, finding a strong substitution effect on own-land. Microdam access and age are also important. Households living nearer to dam sites will plant both species groups there with higher probabilities, but the decision to plant on agricultural own-land is not affected. For older dams with more developed irrigation, households are more likely to grow crops rather than plant trees on their own land, but they plant more trees at the dam sites.

“景村协同”理念下乡村规划路径初探

乡村精准扶贫背景下,"景村协同"发展模式为拥有景区资源的乡村建设提供了新思路。通过梳理我国乡村建设中"景村协同"各个发展阶段特点,明确其存在的问题:定位模糊,缺乏功能互补;基础建设落后,互动性弱;利益主体权责模糊或缺失。提出景村差异化互补发展,加强基础建设与互动,建立统筹管理机构三大措施,并以粤北地区沈家村乡村规划为例进行实证,通过景村精准定位、加强空间联系和协调利益主体关系,打破景村间的隔阂,实现景村协同,共建共荣。     

防霉中密度纤维板的研制

在湿度较大的地区和潮湿的场所,中密度纤维板(下称中纤板)因长期受潮而产生霉变,使其性能受损,更为严重的是污染了居住环境。因此,研究如何防止中纤板霉变,使其具有防霉性能应作为一项重要的课题。笔者通过对防霉剂选择、优化热压工艺参数、防霉效果测试等方面进行了试验研究,确定了适当的防霉剂及其添加量,得出了压制防霉中纤板的优化热压工艺。
