An assessment of Mississippi's nonindustrial private forest landowners knowledge of forestry BMP's

This study examined the knowledge levels of Mississippi Non Industrial Private Forest (NIPF) landowners. Data were collected by passing out surveys to participants in Best Management Practices (BMP) educational programs held in conjunction with County Forestry Association (CFA) meetings across Mississippi. Ten CFA's participated in this study. Educational program participants were asked to fill out a survey with several demographic and BMP questions prior to the educational program. Results show that BMP program participants owned an average of 113 hectares, whereas the average Mississippi NIPF landowner owns 20 hectares. Responses to BMP related questions show that Mississippi NIPF landowners have a low level of knowledge concerning BMP's. This situation is likely similar to other states in the Southeastern United States. It can be assumed that county forestry association members are more active and informed about managing their forest land. Therefore, these results may overestimate the BMP knowledge level all landowners in Mississippi.Improved educational programs for NIPF landowners, along with better communication between foresters, loggers, and NIPF landowners are needed if BMP's are to be implemented effectively in Mississippi and across the southern region.     

How effective are River Basin Management Plans in reaching the nutrient load reduction targets?

Riverine nutrient loads are among the major causes of eutrophication of the Baltic Sea. This study applied the Soil & Water Assessment Tool (SWAT) in three catchments flowing to the Baltic Sea, namely Vantaanjoki (Finland), Fyrisån (Sweden), and Słupia (Poland), to simulate the effectiveness of nutrient control measures included in the EU’s Water Framework Directive River Basin Management Plans (RBMPs). Moreover, we identified similar, coastal, middle-sized catchments to which conclusions from this study could be applicable. The first modelling scenario based on extrapolation of the existing trends affected the modelled nutrient loads by less than 5%. In the second scenario, measures included in RBMPs showed variable effectiveness, ranging from negligible for Słupia to 28% total P load reduction in Vantaanjoki. Adding spatially targeted measures to RBMPs (third scenario) would considerably improve their effectiveness in all three catchments for both total N and P, suggesting a need to adopt targeting more widely in the Baltic Sea countries.Electronic supplementary materialThe online version of this article (10.1007/s13280-020-01393-x) contains supplementary material, which is available to authorized users.     

基于环境质量管理的城市综合环境绩效评估研究

文章以26个省会城市2004~2013年的样本数据,从环境健康、生态保护、资源与能源利用、环境治理等4个方面开展研究,构建了包括4项二级指标、12项三级指标和26项四级指标在内的城市综合环境绩效指标体系。研究发现,大部分城市的综合环境绩效历年差异明显,东、中、西部的环境绩效有明显的差异。因此,文章认为应该进一步优化环境绩效指标体系,充分体现区域差异特点,通过实施城市综合环境绩效考核来提高城市环境质量管理水平。     

人类自我科学管理是实现可持续发展的必然选择

现今人口规模的不断膨胀和物质生活水平的日益提高,对资源和环境造成的压力急剧增加。分析了世界现状和可持续发展面临的挑战之后,提出人类要实现可持续发展必须要进行自我科学管理,分别从人类自我定位、对待科技的态度、人口管理、人类消费管理4个方面进行讨论和阐述。人类首先需重新审视自己,进行自我定位;其次要正确对待科技;控制人口数量和转变不合理消费是目前人类自我管理的重要任务,对此提出一些实施对策。
