Public acceptance potential for reuse applications in Turkey

The water reuse applications are becoming increasingly important in Turkey due to fresh water scarcity problems. However, the success of reuse practices depends on the public's acceptance. Therefore, this study was designed to determine the public awareness, and the potential for acceptance, of reuse applications in Turkey by way of a survey carried out for this purpose. 500 questionnaires were sent to different regions of Turkey and 375 of them were returned. The study indicated that both women and men have concerns about usage of wastewater, especially regarding the use of treated wastewater as drinking water. Results also showed that the area of greatest concern among the public is the health risks associated with recycled water. Respondents of both genders felt that treated wastewater reuse for applications not involving close personal contact was acceptable, due to reduced health risk concerns. On the other hand, the cost of reclamation is another major public concern.     

怀洪新河浮游动物群落特征与水环境因子的关系研究

为研究怀洪新河太湖新银鱼国家级水产种质资源保护区(以下简称保护区)水域浮游动物的群落结构及其与水环境因子的关系,于2014年6月(夏季)在怀洪新河进行采样分析,并对调查区域内的浮游动物及主要环境因子进行了主成分分析(PCA)和典范对应分析(CCA)。结果表明,保护区河段属中营养型河流;保护区浮游动物有4门24属33种,其中轮虫类最多,为11种(占33.33%),其次为原生动物和桡足类,均为8种(占24.24%),最少的为枝角类6种(占18.18%);保护区浮游动物细胞密度平均为1.82×10~4ind./L,生物量平均为2.45mg/L;水温和氨氮是影响水体环境的关键因子;水温、总氮、浊度、氨氮、高锰酸盐指数(COD_(Mn))和pH是影响浮游动物群落结构的主要驱动因子。     

“限塑令”政策有效性评估的实例分析

通过对上海市杨浦区3个居民小区"限塑令"实施前后塑料袋消费情况的调研.发现"限塑令"在一定程度上起到了塑料袋减量化的作用,但效果并不明显.其瓶颈在于我国当前对商品流通领域的控制能力非常薄弱,对非正规零售商约束力度不够、监管缺位,导致他们无视"限塑令"的规定,继续提供免费塑料袋,从而严重架空了"限塑令"的减量化效果.文章中提出了通过加强监管和处罚力度、培育社会参与机制,以及加大公众宣传活动等措施,消除"限塑令"的政策死角,以真正实现塑料购物袋消费减量化的目标.     

Considering agro-ecosystems as ecological funds for collective design: New perspectives for environmental policy

Enhancing agro-ecosystem sustainability raises difficult challenges for environmental policy: it requires both increasing knowledge on these complex systems to design effective solutions and coordinating stakeholders with diverging interests. However, most existing environmental policies consider ecosystems’ desirable properties as given, leading ecosystem managers to favor “turnkey” solutions. How could public policy better support local collective initiatives aiming at reconciling agriculture and the environment? This paper presents an empirical case study from western France, in which a partnership between an agricultural cooperative and an ecological research center resulted in a collective design initiative. We conceptually model this initiative drawing upon recent design theories and Georgescu-Roegen’s ‘fund-flow’ model, defining ‘ecological funds’ as the starting point of a collective design process. The results highlight the importance of developing policy instruments that can better support local innovation processes through greater democratization. Adopting a design approach to sustainable agricultural landscape management could be particularly fruitful in situations where collective action is necessary but where there is no common good recognized as such, and no existing community identified.

Projected impacts to the production of outdoor recreation opportunities across US state park systems due to the adoption of a domestic climate change mitigation policy

Numerous empirical and simulation-based studies have documented or estimated variable impacts to the economic growth of nation states due to the adoption of domestic climate change mitigation policies. However, few studies have been able to empirically link projected changes in economic growth to the provision of public goods and services. In this research, we couple projected changes in economic growth to US states brought about by the adoption of a domestic climate change mitigation policy with a longitudinal panel dataset detailing the production of outdoor recreation opportunities on lands managed in the public interest. Joining empirical data and simulation-based estimates allow us to better understand how the adoption of a domestic climate change mitigation policy would affect the provision of public goods in the future. We first employ a technical efficiency model and metrics to provide decision makers with evidence of specific areas where operational efficiencies within the nation's state park systems can be improved. We then augment the empirical analysis with simulation-based changes in gross state product (GSP) to estimate changes to the states’ ability to provide outdoor recreation opportunities from 2014 to 2020; the results reveal substantial variability across states. Finally, we explore two potential solutions (increasing GSP or increasing technical efficiency) for addressing the negative impacts on the states’ park systems operating budgets brought about by the adoption of a domestic climate change mitigation policy; the analyses suggest increasing technical efficiency would be the most viable solution if/when the US adopts a greenhouse gas reduction policy.
