基于政策工具的中国生物质发电补贴政策评估

生物质发电兼具环境效益与社会效益,对支撑中国推进能源消费革命和乡村振兴,实现碳达峰、碳中和目标具有重要意义。对截至2020年12月31日国家层面出台的生物质发电补贴相关政策进行梳理,运用政策工具理论与方法,从环境、供给、需求3个角度,研发、投资推广、原料资源、生产并网、消费5个环节评估生物质发电补贴政策的实施情况和存在问题,提出生物质发电补贴政策的优化建议。结果表明,现阶段生物质发电产业在研发、原料供应、基础设施领域补贴不足,财政补贴有逐步退坡并向市场机制转变趋势,但相应政策工具及制度创新尚存在欠缺。中国生物质发电补贴政策应在更多关注技术研发、充分涉及中间链条、完善激励机制等方面不断改进,并大力强化市场培育,在配套措施保障下引入市场机制,以促进产业长期可持续发展。     

A review on submarine oil and gas leakage in near field: droplets and plume

The 2010 Deepwater Horizon spill remains the largest catastrophic release of oil and gas into the deep sea. The irrupted oil and gas substantially impact a marine ecosystem, cause human injury, and have high societal opinions. Therefore, understanding the transport and dispersion of subsurface hydrocarbon provides an imperative substratum for the practical assessment and response of marine oil spill accidents. In this review, we summarize the major advances since the Deepwater Horizon accident, with emphasis on the observation and modeling of the droplet and the formation and dynamics of the plume. Additional complexity including more than the investigation of gas-saturated oil at high-pressure and the effect of Earth’s rotation on near field plume is also outlined. We end with a few outlooks on key priorities for more precisely estimations on future oil spills.

Awareness of environmental legislation as a deterrent for wildlife crime: A case with Masaai pastoralists,poison use and the Kenya Wildlife Act

Illegal wildlife crime is a global phenomenon, accelerating the ongoing biodiversity crisis. In the Old World, and particularly in Africa, illegal use of poisons to eliminate carnivores is the main driver of the continental vulture crisis. Knowledge about the underlying source and drivers of this threat is lacking for most areas, including Kenya, a global vulture and biodiversity hotspot. An extensive questionnaire survey of over 1300 respondents was run, using a specialized questioning technique and quantitative analytical approaches. Results show that, while pastoralists have a positive attitude towards vultures, over 20% of them use poisons to eliminate predators. Poisoning was largely driven by livestock losses to predators, and by negative attitude towards predators. Poisoning was less prevalent among respondents aware of the Kenya Wildlife Act. Overall, we suggest that a combination of top-down, e.g. legislation, and bottom-up (such as corrals or compensation) along with awareness campaigns may help reduce poisoning on the ground.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01695-8.
