Green and Low Carbon Development Performance in Farmland Use Regulation: A Case Study of Liyang City, China
Summary
Researchers used system dynamics modeling to simulate the impacts of farmland use regulation scenarios on green and low-carbon development performance across 10 towns in Liyang City, China, finding that scenarios allowing construction land to encroach on farmland produced the lowest comprehensive green development index at 0.23. The study identified spatial heterogeneity in development performance and categorized villages into four types to guide differentiated farmland regulation policies.
Farmland use regulation strictly regulates the conversion of agricultural land for other agricultural purposes and the construction of agricultural facilities, thereby optimizing the land use pattern in rural areas. However, different measures and intensities of farmland use regulation can affect the overall performance of green and low-carbon development in rural areas. This study utilizes system dynamics modeling and simulation to conduct a case study based on current land use data from 10 towns in Liyang City, China. The empirical results indicate the following: (1) Based on comprehensive measurements of green and low carbon development performance, Liyang City exhibits a pattern of higher indices in the south and lower indices in the north. Towns such as Tianmu Lake, Daibu, and Shezhu show relatively high average comprehensive indices of 0.31, 0.30, and 0.28, significantly higher than other towns. (2) Simulation of farmland use regulation’s impact on green and low carbon development performance reveals that Scenario One, involving additional construction land occupying farmland, achieves a comprehensive index of only 0.23, significantly lower than the other scenarios. (3) Based on calculations and field surveys, Liyang City’s villages are categorized into four types, with the largest number being industry-integrated villages (94 villages). Accordingly, policies for farmland use regulation are designed for different village types. Therefore, future farmland use regulation should be tailored with differentiated institutional designs according to the development needs of different villages. This study’s findings provide insights into green and low-carbon development in rural areas.

Analysis of the spatio-temporal evolution of sustainable land use in China under the carbon emission trading scheme: A measurement idea based on the DID model
Researchers applied a difference-in-differences estimation model to assess the effect of China's carbon emission trading scheme on sustainable land use across provinces from a spatio-temporal perspective. The scheme improved sustainable land use in pilot areas from both economic and environmental dimensions, with effects concentrated in eastern regions and urban agglomerations including the Pearl River Delta.

Researchers used a difference-in-differences model on 30 Chinese provincial-level regions from 2005 to 2020 to evaluate which forestry carbon sink mechanism (FCSM) policies most effectively generated socioeconomic value, finding that China's forest carbon policies have underutilized potential for meeting carbon neutrality goals.
Spatiotemporal Evolution of the Coupled and Coordinated Development of the Low-carbon Economy, Green Finance, and Ecological Environmental Quality: Evidence from China
Despite its title referencing low-carbon economy and ecological quality, this paper studies the coordinated development of green finance, carbon reduction, and environmental quality indicators across Chinese provinces — not microplastic pollution. It examines regional economic and environmental policy dynamics using statistical modelling, and is not relevant to microplastics or human health.
