Under the carbon emission pattern of “peak carbon and carbon neutrality”, the policy of crop rotation and fallow system (CRFS) is regarded as an important initiative to promote the green, low-carbon, and high-quality development of agriculture. Focusing on balanced panel data from 30 provinces in China from 2010 to 2021, this paper empirically examines the impact of CRFS on agricultural carbon emissions (ACEI) and its internal mechanism using a multi-temporal difference-in-differences model. The benchmark regression results show that CRFS can significantly reduce ACEI, and the results remain robust after validation by multiple methods. Mechanism results show that CRFS is able to reduce ACEI by reducing factor mismatch and promoting the level of agricultural services. Heterogeneity analysis results show that the arable land fallow rotation system is more conducive to promoting the reduction in agricultural carbon emission intensity in the main grain producing areas, main grain marketing areas, high land transfer areas, and plantation areas than in the grain production and marketing balanced areas, low land transfer, and animal husbandry areas. This study demonstrates the effectiveness of the CRFS policy implementation, provides a doctrinal basis for expanding the scope of CRFS implementation, and provides policy recommendations for relevant departments to improve the CRFS policy.

“…In small scale crops in the urban environment, owners often inadvertently apply excessive doses of pesticides, leaving residues that constitute a threat to the area (Meftaul et al, 2020). Eijsackers and Maboeta (2023) reported that the heavy metal-containing fungicide copper oxychloride, applied under field conditions, can damage soil life.…”

The growth in urbanization and industrialization is causing an increase in environmental pollution in cities and their surrounding areas. Additionally, the growing urban population requires a greater volume of fresh vegetables. In nature, heavy metals (HM) are widely distributed; when they gradually enter the soil-plant-consumer continuum, they are difficult to remove from the system and accumulate at toxic levels. To gain an overview of this situation, the information in the ScienceDirect database was used in accordance with the PRISMA guide. For this, the keywords “vegetable”, “contamination” and “urban” were used in a first step and, in a second step, the keywords “vegetable” and “heavy metal” were used. The most toxic HM for consumers are Cd, Pb, Hg, Cr and As, as well as essential MP for the plant (Zn, Cu, Ni, Fe, Mo). At excessive concentrations these cause neurological and kidney damage, cancer and other forms of damage to health. Crop contamination can come from the atmosphere, irrigation water, and/or the soil itself, proximity to busy roads, industry, polluted rivers, and excessive use of pesticides and fertilizers that contain HM. Plant poisoning by HM causes a decrease in root growth and biomass of the plant, foliar chlorosis, and other physiological alterations. Leafy vegetables (including aromatic herbs) and solanaceous vegetables accumulate the most HM, while cucurbits and legumes are the least affected. Plants that develop for a longer time accumulate a greater amount of HM. In general, to increase the food safety of urban horticulture, more studies are needed on HM contamination, soil aptitude, risk assessment for ingesting intoxicated vegetables, as well as appropriate instructions for the clean handling of these crops in cities and surrounding areas.

Microorganisms, though invisible, they play a pivotal role in influencing both the global economy and societal progress., and job market. This discussion highlights their significant impact on various sectors like food, pharmaceuticals, and chemicals. These versatile microorganisms act as efficient cell factories, producing chemicals from renewable sources and aiding in waste degradation. The historical development of microbial cell factories has relied on a trial-and-error approach, following a cyclic process of design, construction, testing, and refinement. The essay delves into the critical role of microorganisms in sustainable development, highlighting their capacity for sustainable chemical production and waste degradation. The incorporation of microbial technology presents significant opportunities for advancing the United Nations’ Sustainable Development Goals. Microorganisms contribute significantly to sustainable development by influencing the economy, creating jobs, improving food and pharmaceutical production, and advancing chemical manufacturing. Their utilization brings advantages like cleaner production methods, renewable resource utilization, and healthcare contributions. Overall, microorganisms are essential players in sustainable development, offering solutions for a more environmentally friendly and economically viable future.
