An Innovative Restoration Mode “Macrophytes–Fishes–Benthons–Birds” Implemented In Aesthetic Plateau Wetlands, Junxing Yang, Xiaoai Wang, Xiaofu Pan, Yuanwe Zhang, Heqi Wu, Anli Wu

Bulletin of Chinese Academy of Sciences (Chinese Version)

Affected by both increasing human activities and climate change, Yunnan Plateau lakes were faced with threats such as water level decreasing, water-body reducing, and severe pollution. Many indigenous species were endangered or even disappeared. The ecological restorations implemented since 1980s almost all used alien species. As an inevitable result, severe negative impacts from alien species were observed on the Plateau wetland ecosystem and indigenous species. To solve these problems, with the support of relevant projects, an innovative restoration mode mainly with indigenous flag-species “macrophytes – fishes – benthons – birds” was proposed. This innovative mode was implemented respectively in Dianchi …

Atmospheric 14Co2 Observation: A Novel Method To Evaluate Carbon Emissions, Zhenchuan Niu, Peng Wang, Shugang Wu, Weijian Zhou

Bulletin of Chinese Academy of Sciences (Chinese Version)

As an important carbon emitter, China faces the stress of carbon peaking and carbon neutrality goals and international carbon reduction duty. The accurate data of carbon emissions are important to evaluate the carbon peaking and carbon neutrality goals and fulfill the international duty of carbon reduction.

Bulletin of Chinese Academy of Sciences (Chinese Version)

Tall wheatgrass (Elytrigia elongata) is a perennial cool-season bunchgrass with high productivity and tolerance to salt and alkali, waterlogging, and drought. Since first introduced into China in 1950s, tall wheatgrass has long been used as a wild parent for distant hybridization with wheat (Triticum aestivum). During 1980s─1990s, a few tall wheatgrass varieties were introduced to China as forage grass, nonetheless, currently they are still not widely cultivated and no variety was certificated. In 2020, Zhensheng Li put forward a proposal to construct “Coastal Grass Belt” on saline and alkaline soils in the Circum-Bohai sea region, which provides an opportunity for …

Using Satellites To Map The Urban Heat Island Effect And Using Products To Generate Public Action In Harrisonburg, Trevor Brooks, Timothy A. Kreps

ASPIRE 2023

The Urban Heat Island effect (UHI) is a phenomenon where urban centers are hotter than their surrounding rural counterparts. Ever since it was first discovered there have been a variety of methods of mapping this effect from using terrestrial sensors to satellites. This study attempts to evaluate different mapping methods, specifically two different satellite methods (ECOSTRESS and MODIS). As well as a community driven mapping method that involved terrestrial sensors attached to cars. This study then discusses remedies to the UHI and documents efforts to remedy it through a partnership between researchers, the community, and the city of Harrisonburg as …

Carbon Farming: A Preliminary Economic Analysis Of Carbon Credits For No-Till And Cover Crops, Drew Havens, Richard K. Perrin, Lilyan E. Fulginiti

Cornhusker Economics

Summary Based on experimental data about the amount of carbon sequestered and estimated implementation costs, our preliminary results show that the average cost of sequestering carbon via no-till (about $22 per ton of CO₂e) appears to be much lower than the $51 per ton social value of sequestering that ton. In contrast, our preliminary results show that the average costs of sequestration via adoption of cover crops is much higher, about $60 per ton. Depending on how accurate soil carbon models are in predicting sequestration on individual fields to qualify them for enrollment, reimbursement costs for planting cover …

Bulletin of Chinese Academy of Sciences (Chinese Version)

The blue carbon function and carbon sequestration potential of coastal ecosystems, such as salt marshes, mangroves and seagrass beds, have emerged as one of the long-term solutions to mitigate global climate change. However, the blue carbon sequestration technology has been neglected in most ecological protection and restoration projects of coastal ecosystems. Besides, in the process of project implementation and management, the dynamic monitoring and systematic evaluation of carbon sink are imperfect. This study proposes the concept of enhancement of coastal blue carbon, focusing on four key technologies of soil carbon emission reduction technology, plant carbon sequestration technology, soil microbial carbon …
