Special Issue Information

Dear Colleagues,

At present, global agricultural systems are facing unprecedented challenges, particularly climate change, increased disasters, soil degradation, and shortages of agricultural resources, which have all led to a lack of diversity and low productivity in agricultural systems, thereby hindering the achievement of sustainable development goals. Moreover, the global population could reach 9.73 billion by 2050. The agricultural sector faces the challenge of producing enough agricultural products with lower environmental impacts. The sustainable development of agricultural systems is crucial for ensuring global food security. To address these challenges, this Special Issue aims to explore the impact of Agroecology Sustainable Development and Agriculture Environmental Impact Assessment and Measurement for achieving sustainable development.

The purpose of this Special Issue is to provide a platform for researchers to showcase their original research and reviews related to the impact of sustainable agricultural on agriculture, ecosystem sustainability, agriculture environmental impact, and ecological security. The goal is to contribute to the advancement of knowledge in this field and identify effective strategies for addressing the challenges posed by sustainable agricultural.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Impacts on greenhouse gas reduction after sustainable agroecology development.
  • Impacts on soil organic carbon stability after sustainable agroecology development.
  • Assessment and measurement of the impact of sustainable agriculture on the agri-environment.
  • Bio-organic fertilizer replacement of chemical fertilizers to improve sustainable agricultural quality and efficiency technology.
  • Beneficial microorganisms, bio-organic fertilizer development and impacts on agro-ecosystem sustainability potentials.
  • Policy formulation for the sustainable management of regional/global sustainable agricultural in response to serious environmental impacts in agricultural systems, etc.

We look forward to receiving your contributions.

The reduction in agricultural carbon emissions (ACEs) in Shandong Province is essential to China’s carbon peak and carbon neutrality objectives. In this regard, we constructed an ACE inventory for Shandong Province at a resolution of 1 km × 1 km, integrating the emission factor method with geographic information system (GIS) technology. Building upon this, we explored the dynamic evolution patterns of ACEs using kernel density estimation and conditional probability density estimation. Additionally, long short-term memory networks were trained to predict ACEs under various scenarios. The results showed that: (1) ACEs in Shandong Province exhibited two stages of change, i.e., “rise and decline”. Notably, 64.39% of emissions originated from the planting industry. The distribution of emissions was closely correlated with regional agricultural production modes. Specifically, CO2 emissions were predominantly distributed in crop cultivation areas, while CH4 and N2O emissions were primarily distributed in livestock breeding areas. The uncertainty of the emission inventory ranged from −12.04% to 10.74%, mainly caused by emission factors. (2) The ACE intensity of various cities in Shandong Province is decreasing, indicating a decoupling between ACEs and agricultural economic growth. Furthermore, the emission disparities among different cities are diminishing, although significant spatial non-equilibrium still persists. (3) From 2022 to 2030, the ACEs in Shandong Province will show a continuous downward trend. By 2030, the projected values under the baseline scenario, low-carbon scenario I, and low-carbon scenario II will be 6301.74 × 104 tons, 5980.67 × 104 tons, and 5850.56 × 104 tons. The low-carbon scenario reveals greater potential for ACE reduction while achieving efficient rural economic development and urbanization simultaneously. This study not only advances the methodology of the ACE inventory but also provides quantitative references and scientific bases for promoting low-carbon, efficient, and sustainable regional agriculture.

This study was aimed at problems associated with low fertilizer using efficiency, excessive nitrate content of vegetables, and soil degradation in greenhouse vegetable production. A pot experiment was conducted to assess the effects of applying biochar-coated nitrogen fertilizer (BCNF) on the yield, quality, and nitrate content of bok choy (Brassica rapa subsp. Chinensis) as well as on soil nutrients in greenhouses. Four treatments were set up as follows: no nitrogen fertilizer application (BA), chemical nitrogen fertilizer application (CK), biochar-coated nitrogen fertilizer application (BCNF, the amount of nitrogen was equal to that of chemical fertilizer), and reduced biochar-coated nitrogen fertilizer application (D-BCNF, the amount of fertilizer was 80% of BCNF). Compared with the other treatments, BCNF treatment increased chlorophyll content, plant height, maximum leaf length, maximum leaf width, and other biological characters of bok choy. Compared with CK treatment, BCNF treatment increased the fresh weight of bok choy by 14.02%, while reducing the root–shoot ratio and nitrate content by 19.1% and 46%, respectively. It was further found that the application of BCNF could effectively increase the content of soil organic matter; reduce the leaching loss of nitrate nitrogen, exchangeable calcium and magnesium; and effectively improve nitrogen use efficiency. Therefore, the application of BCNF can not only reduce the loss of fertilizer nutrients, promote plant growth, and improve fertilizer utilization, but it can also improve soil nutrients, fix carbon, and reduce emissions. It is a new type of environmental protection fertilizer with application prospects. Full article
