Land-based carbon sequestration projects, such as tree planting, are a prominent strategy to offset carbon emissions. However, we risk reducing natural ecosystems to one metric - carbon. Emphasis on restoring ecosystems to balance ecosystem services, biodiversity conservation, and carbon sequestration is a more appropriate strategy to protect their functioning.

Understanding the molecular basis of regulated nitrogen (N) fixation is essential for engineering N-fixing bacteria that fulfill the demand of crop plants for fixed nitrogen, reducing our reliance on synthetic nitrogen fertilizers. In Azotobacter vinelandii and many other members of Proteobacteria, the two-component system comprising the anti-activator protein (NifL) and the Nif-specific transcriptional activator (NifA)controls the expression of nif genes, encoding the nitrogen fixation machinery. The NifL-NifA system evolved the ability to integrate several environmental cues, such as oxygen, nitrogen, and carbon availability.

Nanoplastics (NPs) in marine ecosystems have garnered increasing attention for their interference with the physiological processes of aquatic organisms. An in-depth examination of the toxicological responses of Nannochloropsis oceanica, a species vital to marine ecosystems, is essential due to the crucial role of lipid metabolism in carbon sequestration and energy allocation in microalgae. This study analyzed the toxicological responses of N.

Excessive use of conventional potassium chloride (KCl) fertilizer has led to soil degradation problems such as compaction and salinization. While controlled-release potassium chloride (CRK) fertilizer has the potential to enhance crop productivity and mitigate these problems, its impact on soil quality (SQ) remains unclear. In this study, four potassium (K) fertilization treatments were established: no K application (CK), conventional KCl fertilizer (CRK0), 50 % substitution with CRK (CRK0.

The growing demand for food has led to overuse of land, exacerbating the environmental sustainability of agrifood systems. Insufficient coordination and coupling within agrifood systems (soil-crop-animal-food consumption) reduce material cycle efficiency and limit the system's carbon reduction potential. Given the lack of global research on the impact of system coupling on carbon reduction, the value of regional practice cases is particularly evident.

Background: Strongly water-sensitive reservoirs with high clay content face challenges in conventional development due to clay swelling and impeded seepage. CO2 injection shows potential for enhanced oil recovery (EOR) and carbon sequestration; however, the role of clay minerals in regulating CO2-induced asphaltene deposition and sequestration remains unclear.
Methodology: We conducted experiments on clay-oil interactions, nuclear magnetic resonance (NMR), measurements of crude oil properties, and long core water flooding tests to evaluate deposition, reservoir damage, and CO2 sequestration.
