The targets of limiting global warming levels below 2°C or even 1.5°C set by Paris Agreement heavily rely on bioenergy with carbon capture and storage (BECCS), which can remove carbon dioxide in the atmosphere and achieve net zero greenhouse gas (GHG) emission. Biomass and coal co‐firing with CCS is one of BECCS technologies, as well as a pathway to achieve low carbon transformation and upgrading through retrofitting coal power plants. However, few studies have considered co‐firing ratio of biomass to coal based on each specific coal power plant's characteristic information such as location, installed capacity, resources allocation, and logistic transportation. Therefore, there is a need to understand whether it is worth retrofitting any individual coal power plant for the benefit of GHG emission reduction. It is also important to understand which power plant is suitable for retrofit and the associated co‐firing ratio. In order to fulfill this gap, this paper develops a framework to solve these questions, which mainly include three steps. First, biomass resources are assessed at 1 km spatial resolution with the help of the Geography Information Science method. Second, by setting biomass collection points and linear program model, resource allocation and supply chain for each power plants are complete. Third, is by assessing the life‐cycle emission for each power plant. In this study, Hubei Province in China is taken as the research area and study case. The main conclusions are as follows: (a) biomass co‐firing ratio for each CCS coal power plant to achieve carbon neutral is between 40% and 50%; (b) lower co‐firing ratio sometimes may obtain better carbon emission reduction benefits; (c) even the same installed capacity power plants should consider differentiated retrofit strategy according to their own characteristic. Based on the results and analysis above, retrofit suggestions for each power plant are made in the discussion. [ABSTRACT FROM AUTHOR]

The relationship between rural labour transfer and cultivated land use has always been a hot topic in academic field and government management. Here, by using the large‐scale survey data of 1,868 farmers from 37 villages in Jianghan Plain and the low‐hill areas in southeastern Hubei province, we investigated the relationship between rural labour force transfer and decision‐making in cultivated land use from the perspective of terrain heterogeneity. The findings indicate that under different terrain conditions, there are significant differences in the decision‐making of farmers concerning cultivated land use, leading to different land use efficiencies in different areas. Specifically, rural labour force transfer enhances land use efficiency in plain areas; however, it does not affect that in the low‐hill areas. In addition, we found that in the plain areas, improving the quality of rural household labour can increase the cultivated land use efficiency, while in low‐hill areas, enhancement of geographical accessibility is the key to improving land use efficiency.

The article focuses on the blight on the leaves of garlic observed in Dangyang County in Hubei Province, China from autumn 2004 to spring 2007. The plant disease initially manifested small and white lesions which eventually progressed to apical necrosis that lasted until the leaves withered. Using potato sugar agar (PSA), isolations were made. Pieces of autoclaved filter paper were placed on the agar to induce sporulation. The fungus was identified as Stemphylium solani based on Elli. Sequences in GenBank were compared based on the genomic data extracted from three isolates which showed 99% similarity with S. solani. Pathogenicity tests indicate that the leaf blights were caused by S. botryosum, S. vesicarium (Boiteux et al, 1994) or Cladosporuim echinulatum (Pal and Basuchaudry, 1976).
