Summary: Using a crop growth model and life cycle assessment (LCA), we examined the global warming intensity and greenhouse gas mitigation potential of biofuel systems based on switchgrass grown on marginal land in Michigan, USA. The results showed that switchgrass grown on marginal lands in Michigan can annually produce over 0.57 hm3 of liquid biofuel, mitigating 1.2-1.5 Tg of CO2 emissions. The majority of these biofuels meet the Renewable Fuel Standard and are carbon-negative, but carbon intensities could increase on certain lands with high soil organic carbon levels.

Summary: This study utilizes a methodology to conduct cost analyses on a spatial basis and relates them with environmental factors in Eskisehir province, Turkiye in order to encourage cost-effective switchgrass cultivation. The findings show that switchgrass agriculture on suitable lands does not guarantee a fixed profitability rate or dry product sales price, leading to the determination of different sales prices based on profitability ratios. The method highlights the importance of integrating cost-affecting parameters into spatial analysis for site selection.

Summary: In 2017, the United States produced over 66.2 billion Liters of biofuel, mainly corn ethanol (61 billion Liters) and soybean biodiesel (6 billion Liters), for the transportation industry. This study utilized a model framework and high-resolution input datasets to evaluate the sustainability of corn ethanol and soybean biodiesel in most counties of the United States. The results showed that these biofuels produced a total greenhouse gas emission volume of 99.5 million Mg CO2-eq in 2017, with a combined carbon intensity of 65.3 gCO2-eq/MJ. However, the production of these biofuels incurred additional economic costs and had unfavorable impacts on water, land, and nitrogen intensity compared to petroleum-based fuels.

Summary: India is committed to increasing the use of renewable energy and aims to install 450 GW of renewable energy by 2030. Bioenergy can help balance the seasonal and hourly power demands, but sustainable production and consumption are vital for achieving targets. Modeling future bioenergy pathways in India reveals concerns over water availability, greenhouse gas emissions, air pollution, and land use change. Higher demand for bioenergy crops increases water demand and competition for land, raising concerns for food security. However, improving water use efficiency and establishing supply chains can minimize impacts and alleviate potential negative effects.

Summary: With the increasing global carbon dioxide emissions, China has proposed the goals of carbon peak and carbon neutrality (double carbon) and formulated an action plan to enhance the carbon sink capacity of the ecosystem. However, there is a lack of research on carbon sources and sinks in the Chinese grassland ecosystem (CGE), thus it is urgent to integrate and analyze them on a national scale. This study estimated the net ecosystem productivity (NEP) of the CGE and found a high differentiation in the northwest and low in the southeast of China. The results showed that precipitation positively correlated with NEP while temperature negatively correlated with it.

Summary: This study analyzes the fluctuation trends and stability of carbon sink in forest ecological space and grassland ecological space, and investigates the impact of precipitation and temperature on the fluctuation process of carbon sink. The results show that precipitation is the dominant influencing factor, with a positive effect on carbon sink. In regions with variable climate, precipitation and temperature have relatively little impact on carbon sink, and their fluctuations depend more on the ecosystem's regulation ability and response to changes in atmospheric CO2 concentration.
