Abstract. High-accuracy atmospheric (carbon dioxide) CO2 concentration data are critical in understanding the global carbon cycle, but there is still a lack of high-resolution product with long-term and seamless coverage. In this study, continuous 8-day XCO2 (column-averaged dry air mole fraction) (GCXCO2) was reconstructed at spatial resolution 0.05° from 2000 to 2020, based on OCO-2 satellite data. An ensemble machine learning stacking regression model, which combines light gradient boosting (LGBM), extreme (XGB), extremely randomized trees (ETR), (GBR), random forest (RF), utilized model relationships between auxiliary satellite, simulation data, meteorological A dynamic normalization strategy developed handle great temporal variation issue ensure expansion prediction model. Multiple validation methods were applied comprehensively evaluate generalization ability product. The 10-fold cross-validation shows an overall satisfactory result scale, R2 = 0.974 root-mean-square error (RMSE) 0.551 ppm (parts per million). Further extension experiments also proved that dependable results could be obtained regions time periods without valid observations (R2 0.958 0.886, respectively). Compared Total Carbon Column Observing Network (TCCON) ground station observations, GCXCO2 performs better than demonstrating accuracy higher resolution. Based product, upward annual trend approximately 2.09 ppm/year can found for significant differences Northern Southern hemispheres different seasons. This may well first remote sensing-based high-precision dataset, will help advance climate change balance. dataset freely https://doi.org/10.5281/zenodo.10083102 (Guan Sun, 2023).

Climate change is one of the most significant challenges worldwide. There strong evidence from research that climate will impact several food chain-related elements such as agricultural output, incomes, prices, access, quality, and safety. This scoping review seeks to outline state knowledge supply chain's vulnerability identify existing literature may guide future research, policy, decision-making aimed at enhancing resilience chain. A total 1526 publications were identified using SCOPUS database, which 67 selected for present study. The assessment methods well adaptation measures have been employed alleviate in chain discussed. results revealed a growing number providing weakening due extreme weather events. Our demonstrated need broaden into entire various forms climatic variability because studies concentrated on relationships between fluctuations (especially rainfall, temperatures, drought) production. lack about effects underlying socio-economic consequences could result underperformance or failure

Climate change significantly impacts small-scale agriculture, with limited adaptation capabilities due to lack of access advanced science and technology. Traditional methods are ideal, but modern adaptations require significant financial investment, affecting the smallholder under-resourced agricultural sector's economic activities. The study analyzed climate drivers among vegetable farmers, using a representative sample 244 farmers from four villages through face-to-face interviews semi-structured questionnaires. Using Logistic regression model, results showed resources (extension services), institutional (association membership) societal influence (farm produce theft, animal trespassing in farming plots) be associated use measures area. recommends expanding extension services, strengthening community policing, creating grazing guidelines, training on causes, social cohesion, mitigation strategies address farm theft trespassing. contributes new knowledge discourse by providing empirical evidence pointing out need consider critical non-climate factors for when making interventions sector.
