The change in the socio-political formation of Russia from a socialist planned system to a capitalist market system significantly influenced agriculture and one of its components—arable land. The loss of the sustainability of land management for arable land led to a reduction in sown areas by 38% (from 119.7 to 74.7 million ha) and a synchronous drop in gross harvests of grain and leguminous crops by 48% (from 117 to 61 million tons). The situation stabilized in 2020, with a sowing area of 80.2 million ha and gross harvests of grain and leguminous crops of 120–150 million tons. This process was not formalized legally, and the official (legal) area of arable land decreased by only 8% from 132.8 to 122.3 million ha. Legal conflict arose for 35 million ha for unused arable land, for which there was no classification of its condition categories and no monitoring of the withdrawal time of the arable land from actual agricultural use. The aim of this study was to resolve the challenges in the method of retrospective monitoring of soil–land cover, which allowed for the achievement of the aims of the investigation—to elucidate the history of land use on arable lands from 1985 to 2025 with a time step of 5 years and to obtain a detailed classification of the arable lands’ abandonment degrees. It was also established that on most of the abandoned arable land, carbon sequestration occurs in the form of secondary forests. In the course of this work, it was shown that the reasons for the formation of an array of abandoned arable land and the stabilization of agricultural production turned out to be interrelated. The abandonment of arable land occurred proportionally to changes in the soil’s natural fertility and the degree of land degradation. Economically unprofitable lands spontaneously (without centralized planning) left the sowing zone. The efficiency of land use on the remaining lands has increased and has allowed for the mass application of modern farming systems (smart, precise, landscape-adaptive, differentiated, no-till, strip-till, etc.), which has further increased the profitability of crop production. The prospect of using abandoned lands as a carbon sequestration zone in areas of forest overgrowth has arisen. Full article

Amid the urgent need to align agricultural practices with the United Nations Sustainable Development Goals (SDGs), this study examines the role of agricultural digitalization in promoting sustainable and green development in China. Specifically, it explores demand-side factors that drive improvements in agricultural green development and categorizes development models into three types: market-oriented, policy-driven, and innovation-driven. Utilizing provincial-level data from 2011 to 2021, this study employs semiparametric and spatial Durbin models to empirically assess the effects, underlying mechanisms, and regional disparities of agricultural digitalization in advancing green development. The main findings are as follows: (1) Overall, both agricultural digitalization and the level of green agricultural development have gradually increased during the study period, with agricultural digitalization significantly contributing to sustainable agricultural development. (2) The impact of agricultural digitalization on green agricultural development shows an upward trend in eastern, coastal, and non-grain-producing regions, as well as in the southeastern areas of the “Hu Huanyong Line”. In contrast, inland regions and the northwestern areas of the “Hu Huanyong Line” exhibit a U-shaped relationship, and grain-producing regions experience a clear inhibitory effect. Additionally, the promoting effect of agricultural digitalization is more pronounced in regions with higher levels of green agricultural development. (3) Agricultural digitalization generates positive spillover effects, benefiting not only the local region but also surrounding areas, with a stronger radiative effect on neighboring regions. (4) Mechanism analysis suggests that under all three development models, agricultural digitalization can effectively enhance green agricultural development by improving the alignment of supply and demand for green agricultural products, accelerating the establishment and promotion of green agricultural brands, strengthening environmental regulation, fostering new agricultural business entities, advancing agricultural mechanization, and improving the efficiency of facility agriculture.

An accurate assessment of food security and its challenges is essential for formulating effective measures and promoting sustainable socioeconomic development. This study develops an evaluation system for China’s food security, focusing on four dimensions: food supply, food access, food production stability, and food continuity. The entropy weight extended matter element model is used for quantitative processing, which ensures that the integrity of the information can be guaranteed to a greater extent while reducing the influence of subjective factors, and then, the study evaluates the food security of different functional areas in China, and finally, it diagnoses the main obstacles to food security by using the obstacle degree model. (1) From 2000 to 2020, China’s food security level fluctuated, initially declining, and then increasing. The food security level in major production and marketing areas is generally higher, while the primary marketing areas exhibit the lowest security levels. (2) The level of grain yields and the total power of machinery per unit area are the key factors affecting food security; the impact of inputs of agricultural materials (fertilizers and pesticides) on food security has decreased and is constantly stabilizing. In the main marketing area, the per capita food share is significantly lower than in the other functional areas, which has the greatest impact on food security. (3) Analysis of the obstacle factors reveals that the food supply and access security subsystems are crucial for ensuring national, production, and marketing security. From 2000 to 2020, the average obstacle degrees of food supply and food access security at the national level were 46.56% and 21.17%, respectively; for the production and marketing areas, they were 58.47% and 21.45%; and for primary marketing areas, they were 37.69% and 26.59%. In major grain-producing areas, the main obstacles lay within the food supply security and food production stability subsystems, with average obstacle degrees of 53.77% and 15.67%, respectively, from 2000 to 2020. The above results provide a scientific basis for comprehensively improving the level of food security in China, optimizing the structure of food production in each functional area, and formulating regionalized policies for stabilizing and maintaining food production and supply.

Agricultural green total factor productivity (AGTFP) is vital to sustainable agricultural development (SAD), which plays a pivotal role in achieving high-quality economic growth in China. The current research quantified China’s AGTFP from 2007 to 2019 with the Super-SBM model and the GML index. Subsequently, it examined the impact of environmental regulation (ER) on AGTFP and its heterogeneity. Finally, this study developed a mediating effect model and a panel threshold model to investigate the role of technological innovation (TI) in affecting environmental regulation (ER) on AGTFP. The findings indicate that the following: (1) The average annual growth rate of AGTFP is 7.84%, which is mostly driven by green technological innovation progress. (2) ER has a significant positive impact on AGTFP with noticeable regional differences. The eastern and central regions experience a more substantial promotion effect compared to the western region. Additionally, the prominent grain-producing areas and main grain-marketing areas have a more significant promotion effect compared to the grain-balanced areas. The promotion effect of heterogeneous ER on AGTFP varies, with the effects of command-and-control environmental regulation (ERC), market-based incentives for environmental regulation (ERM), and public participation regulation (ERP) decreasing in magnitude. (3) The mechanism analysis reveals that promoting TI is a crucial way to enhance AGTFP through ER. There exists a notable dual threshold for TI in ER, encompassing both ERC and ERM. Moreover, AGTFP becomes increasingly pronounced. This study presents a novel perspective for promoting SAD, with a focus on the rise in AGTFP and the path to achieving it. Full article

Global grain production faces severe risks and challenges, such as the complex and volatile international situation and the frequent occurrence of extreme weather events. The effectiveness of national policies intended to support grain production security is becoming increasingly important. China has implemented a range of policies to promote grain production and increase the incomes of grain farmers. This study constructed a policy quantification model using a content analysis method to quantitatively analyze the various grain production support policies issued by the Chinese government. The application of sensitivity models and the difference-in-differences model to study the spatial response of China’s grain production to these policies enabled an assessment of the future policy trends of China, with the aim of enhancing grain production security. Grain production in the main grain-producing areas (MGPAs) responded best to the policy, the grain production–marketing-balanced areas (GPMBAs) were the second most responsive, and the main grain-marketing areas (MGMAs) responded to the policy to a lesser extent. The direct grain subsidy policy significantly contributed to an increase in grain production, especially in the MGPAs. The results of the study suggest that it would be more prudent for China’s future grain policy to guide the centralization of grain production toward the MGPAs. It will also be necessary to ensure that the government’s various support policies and subsidy funds are inclined toward the MGPAs, and the compensation mechanism should be improved to serve the interests of the MGPAs in terms of resources, ecology, and economy. This will help to enhance the comprehensive production capacity and production efficiency of the MGPAs, thereby guaranteeing China’s food security. Full article

In the modern conditions of the growing consumer market for environmentally friendly industries, the issue of optimizing resource-intensive and energy-intensive technological chains is acute. One of the most expensive stages is the storage of grain—raw materials for the production of biodiesel. This is due to there being no unified temperature control system. In this paper, the authors have developed a mathematical model and a hardware–software complex that allows for the measurement of the temperature field in grain storage areas. To address this challenge, the authors employed methodologies derived from spatial distributed systems to construct a mathematical model. The development of a technical device and the implementation of a software module for processing the measured data in C++ Builder were then undertaken. Full article

Promoting the sustainable development of agriculture is the basis of reducing the poverty rate, ensuring food security, and promoting common prosperity. In order to explore the impact of industrial capital and commercial capital on the sustainable development of agriculture, this paper starts from the perspective of agriculture and conducts empirical tests based on the panel data of 30 provinces in China (except Tibet) from 2013 to 2022, using the fixed-effect model and spatial spillover effect model. The results included the following: (1) industrial capital and commercial capital can significantly promote the sustainable development of agriculture, and this conclusion was still valid after endogenous test and robustness test; (2) a heterogeneity test showed that industrial capital and commercial capital has a stronger role in promoting the sustainable development of agriculture in non-major grain producing areas, areas with high marketization level and central and western regions; (3) the test of the transmission mechanism showed that industrial capital and commercial capital can promote the sustainable development of agriculture by optimizing agricultural production conditions, improving rural environment and promoting farmers’ poverty reduction and common prosperity; (4) further research showed that industrial and commercial capital has a positive spillover effect on the sustainable development of agriculture in neighboring areas while promoting the sustainable development of agriculture in this region. Based on the above conclusions, this paper puts forward some countermeasures and suggestions, such as improving rural infrastructure construction, strengthening efforts to guide industrial and commercial capital to the countryside, and paying attention to the differentiation of industrial and commercial capital investment development.

Fertilizer carbon emissions contribute the largest proportion to agricultural carbon emissions in China, while the extension of low-carbon fertilization technologies (LCFTs) is an effective measure to address this issue. Research suggests that the relational networks surrounding farmers significantly influence their carbon reduction behavior. This study conducted a field survey of 239 large-scale grain producers in August 2022 on China’s Poyang Lake Basin, which is the nation’s largest freshwater lake and a vital agricultural production area. Using cross-sectional data, probit and ordered probit models were employed to analyze the impacts of multidimensional relational networks (market, government, and social networks) on the adoption of LCFTs by large-scale grain producers. Additionally, a mediating-effect model was used to examine the pathways through which relational networks influence LCFT adoption. The findings indicated that relational networks not only increased the likelihood of large-scale grain producers adopting LCFTs but also enhanced the intensity of adoption. However, the effects of different relational networks on low-carbon behavior varied. The market network exerted the most prominent influence on LCFT adoption, followed by the social and government networks. A mediation analysis identified information sharing, demonstration effects, and resource guarantees as the mediating pathways between multidimensional relational networks and LCFT adoption by large-scale grain producers. Furthermore, a heterogeneity analysis revealed that the effects of multidimensional relational networks on LCFT adoption differed across generations and carbon intensity levels. The impact was greater among older grain producers than the younger generation, and those in the high-carbon-intensity group exhibited a stronger incentive compared to the medium- and low-carbon-intensity groups.

Sorghum is a climate-resilient crop which has been cultivated as a staple food in the semi-arid areas of Africa and Asia for food and nutrition security. However, the current climate change is increasingly affecting sorghum performance, especially at the flowering stage when water availability is critical for grain filling, thus lowering the sorghum grain yield. The development of climate-resilient, biotic and abiotic stress-tolerant, market-preferred, and nutrient-dense sorghum varieties offers a potentially cost-effective and environmentally sustainable strategy for adapting to climate change. Some of the common technologies for sorghum improvement include mass selection, single seed descent, pure line selection, and marker-assisted selection, facilitated by backcrossing and genotyping using molecular markers. In addition, recent advancements including new machine learning algorithms, gene editing, genomic selection, rapid generation advancement, and recycling of elite material, along with high-throughput phenotyping tools such as drone- and satellite-based images and other speed-breeding techniques, have increased the precision, speed, and accuracy of new crop variety development. In addition to these modern breeding tools and technologies, enhancing genetic diversity to incorporate various climate resilience traits, including against heat and drought stress, into the current sorghum breeding pools is critical. This review covers the potential of sorghum as a staple food crop, explores the genetic diversity of sorghum, discusses the challenges facing sorghum breeding, highlights the recent advancements in technologies for sorghum breeding, and addresses the perceptions of farmers on sorghum production under the current climate change conditions.

With the aim to characterise the situation of the subsector, 25 poultry farms of the endangered native Utrerana chicken egg-laying-oriented breed (Gallus gallus Linnaeus, 1758) were surveyed in Andalusia (southern Spain) from 2021 to 2023 to investigate the structure of the farms, number of birds, health status, feeding management, and marketing of their products. It was found that the pace of foundation of Utrerana chicken farms accelerated from 2009, and most of the farms were concentrated in the province of Seville. Only 40% of the farms were legally registered. This breed is raised on small farms mainly dedicated to self-supply and raising birds for conformation and their aesthetic values, with limited marketing of eggs and meat, with facilities consisting often of one poultry house and one outdoor enclosure, and with a low number of laying hens per farm (53.5 on average). Current productivity is low, with an average of 139 eggs per hen per year, but hens have a long reproductive lifespan, averaging 4 years. The Partridge variety of the breed was the most common, followed by the Black-barred and Black varieties, while the White variety was very scarce, with only 31 specimens in total. Two-thirds of the farmers also raised other breeds of chickens, in addition to the Utrerana. The management and production system was free-range or backyard, with a certain proximity to the requirements of European Union-certified organic production with regard to stocking densities and generally with a good sanitary status, respect for welfare, and implementation of biosecurity measures on the farms. The feeding of the chickens was based on grazing in outdoor enclosures and on the provision of grains and compound feed, with 40.0% of farmers using commercial compound feed and half preparing feed themselves. Two-thirds of the farmers were affiliated with the National Association of Utrerana Chicken Breeders (“Asociación Nacional de Criadores de Gallinas Utreranas”, ANCGU, in Spanish); almost half of them took part with their birds in fairs and conformation shows, such as the Utrerana Chicken Fair held in Utrera (province of Seville) and more than a quarter of them have sold live birds of the breed at these fairs. The farmers carry out few promotional and advertising activities for their farms and products, predominantly by using social networks, and the market area reached is mainly local. In conclusion, this research has shown that the current alternative production system for Utrerana chicken is similar to that of the hens that originated the breed and consists of a few amateur farms, with a small number of birds, distributed mainly throughout the Andalusian countryside. It has been highlighted that there is a need for the livestock authorities to implement programmes for supporting farmers and promoting the breeding of this endangered avian breed, native to the Spanish zoogenetic heritage.

The capacity of agricultural cultivation for carbon sequestration and emission reduction plays a key role in advancing the green and sustainable development of agriculture and achieving both emission reduction and carbon sink objectives. This study constructs an index for agricultural carbon sequestration and emission reduction capacity using spatial autocorrelation analysis, Theil index, and kernel density estimation, to thoroughly explore spatiotemporal changes and regional differences in carbon sequestration and emission reduction capacity across China and its different grain functional areas. Major findings include: (1) From 2000 to 2020, China’s agricultural carbon sequestration and emission reduction capacity exhibited a fluctuating upward trend, consistent in grain main production areas, while production–consumption and main marketing areas showed a fluctuating decline. (2) From 2000 to 2020, positive spatial correlation in carbon sequestration and emission reduction capacity increased at both national and regional levels, particularly in the main production and production–consumption areas, while the main consumption areas demonstrated a trend toward negative correlation. (3) The Theil index of China’s agricultural carbon sequestration and emission reduction capacity showed an overall fluctuating increase, with interregional differences contributing over 54%, significantly surpassing intra-regional contributions. Moreover, the main producing regions are the main source of the overall national variance. (4) Kernel density analysis highlights that there are significant differences in the distribution and evolution of carbon sequestration and emission reduction capacity among different grain functional areas, and the overall development is unbalanced. Therefore, each region needs to formulate tailored measures to improve agricultural carbon sequestration efficiency, promote regional sustainable development, and achieve carbon reduction goals.

Efficient agricultural input is crucial for agricultural green production and sustainable development. The swift evolution of information and communication technologies has diversified the avenues through which farmers access information. However, how different information channels affect farmers’ production input remain poorly understood. Leveraging a two-way fixed-effects model and the Karlson-–Holm–Breen (KHB) method, this study delves into the mechanisms underlying the influence of both traditional and modern information channels on farmers’ inputs of seeds, chemical fertilizers, and pesticides (SCFP) based on over 15,000 sample of Chinese farmers. The findings reveal the following: (1) modern information channels significantly decrease farmers’ SCFP input, whereas traditional channels exhibit the opposite effect; (2) environmental pollution perception acts as a mediator in the influence of both traditional and modern information channels on farmers’ SCFP input; (3) traditional information channels significantly promote farmers’ SCFP input in the grain production and marketing balance areas, and modern information channels inhibit farmers’ SCFP input in major grain-producing areas; and (4) traditional and modern information channels have an impact on farmers’ SCFP input in the western region, but not in the central region. To promote sustainable agricultural development, government departments should enhance rural Internet access, diversify information sources, advocate for eco-farming, ensure regional digital equity, and enhance green agri-tech promotion.

The outbreak of Russia-Ukraine conflict casted an impact on the global food market, which was believed to be attributed to that Ukraine has suffered significant production losses due to cropland abandonment. Nevertheless, recent outbreaks of farmer protests against Ukraine’s grain exports demonstrated that the production losses might not be as severe as previous estimates. By utilizing the adaptive threshold segmentation method to extract abandoned cropland from the Sentinel-2 high-resolution imagery and calibrating the spatial production allocation model’s gridded crop production data from Ukraine’s statistical data, this study explicitly evaluated Ukraine’s crop-specific production losses and the spatial heterogeneity. The results demonstrated that the estimated area of abandoned cropland in Ukraine ranges from 2.34 to 2.40 million hectares, constituting 7.14% to 7.30% of the total cropland. In Ukrainian-controlled zones, this area spans 1.44 to 1.48 million hectares, whereas in Russian-occupied areas, it varies from 0.90 to 0.92 million hectares. Additionally, the total production losses for wheat, maize, barley, and sunflower amount to 1.92, 1.67, 0.70, and 0.99 million tons, respectively, with corresponding loss ratios of 9.10%, 7.48%, 9.54%, and 8.67%. Furthermore, production losses of wheat, barley, and sunflower emerged in both the eastern and southern states adjacent to the conflict frontlines, while maize losses were concentrated in the western states. The findings imply that Ukraine ought to streamline the food transportation channels and maintain stable agricultural activities in regions with high crop production. Full article

Mycotoxin research is facing unprecedented challenges, starting from the urgent need to cope with the consequences of climate change, the global shortage of grain due to unstable political scenarios, and the major transformation of the supply chains after the COVID-19 pandemic. In this scenario, the mycotoxin contamination of human and animal foods is still unavoidable, thus representing a major challenge to global food security. Next to this, the shift to sustainable and circular food production might be accompanied by an increase in food safety issues involving mycotoxins, e.g., when new technologies are applied to reuse side streams from the food industry, it is not known if and how mycotoxins accumulate in these by-products. MycoTWIN is an EU-funded Horizon 2020 project which fosters knowledge transfer and scientific cooperation within the Mediterranean area, involving worldwide experts, decision makers, and stakeholders in the field of mycotoxigenic fungi and mycotoxins. The MycoTWIN project hosted working group meetings, whose aim was to propose operational plans and/or scientific strategic plans to shape the future research directions to better cope with these challenges. In the working group cycle “Future proof approaches for the management of toxigenic fungi and associated mycotoxins along the food chain”, a multi-actor group was guided in co-creation exercises to elaborate on future research directions and propose relevant actions to be implemented for the present to long-term time periods. The discussion focused on three main topics relevant to the assessment and management of risks associated with mycotoxins and toxigenic fungi: (i) needs for the harmonization of molecular and chemical methods and data analysis, (ii) from lab research to marketable solutions: how to fill the gap, and (iii) gaps in data quality for risk assessment.

Agricultural service trade is closely related to the promotion of the sustainable development of China’s agriculture and is necessary for comprehensive rural revitalization. To clarify the relationship between trade in agricultural services and agricultural green total factor productivity (AGTFP) from a macroscopic perspective and then analyze the acting path and threshold effect, can provide an important reference for improving agriculture’s green level and realizing the sustainable development of agriculture. This paper uses the provincial panel data of China from 2007 to 2022 to measure agricultural green total factor productivity (AGTFP) using the SBM-GML model and explores the impact of agricultural service trade on AGTFP with the help of the fixed effect model, the mediation effect model, and the threshold model. According to this study: (1) Trade in agricultural services can significantly increase AGTFP. (2) Mechanism analysis shows that trade in agricultural services can promote AGTFP through promoting industrial agglomeration, enhancing technological innovation, and improving factor allocation. (3) Heterogeneity analysis shows that trade in agricultural services has a more obvious role in promoting AGTFP in the eastern region and the main grain marketing area. (4) The threshold effect finds that the promotion of agricultural services trade on AGTFP will gradually increase as the level of government support rises. Therefore, China should actively promote the development of agricultural service trade, implement the concept of sustainable development, improve the level of government support, and promote the improvement in agricultural total factor productivity and sustainable development.
