Global food security (GFS) is challenged by increasing food demand due to population growth and climate change. International trade and globalization have underpinned GFS until the most recent public health, geopolitical and economic crises, when virtually overnight, the focus of governments has shifted towards domestically and locally produced foods. However, the agri-food sector has limited flexibility, and relatively long periods are needed for fundamental/sustainable changes. One of the crucial factors enabling GFS is the efficient water management, but the required knowledge and capabilities are often lacking regionally/locally. We propose the Centers for Optimizing Water Management in Agroecosystems as a long-term solution. The Centers would be the specialized hubs for promotion of research, innovation and technology transfer, raising the knowledge of stakeholders (farmers, extension and government officials, scholars, students, policymakers and other professionals) and their capacities in water management. These Centers would operate as research/education/technology demonstration entities tailored to the specifics of a particular country/region, aiming to address the most important and pertinent goals and outcomes with a high-spatial-resolution outreach. Finally, the Centers will improve farmers’ livelihoods, contribute to sustainable and efficient use of agro-environmental resources, and increase productivity and food quality, ultimately supporting GFS.

This study investigates local food producers’ economic sustainability by examining the impact of six variables: external and internal barriers, the number of economic operators, the imbalance of power, the number of distribution options, and waste.The investigation uses mixed methods of questionnaires and interviews. The data was collected using a self-completed questionnaire, which was answered by 57 local food producers across Norway, and four semi-structured interviews with professionals in the food industry. The quantitative data was analyzed with the use of partial least squares structural equation modeling (PLS-SEM), and the qualitative data was analyzed using a thematic analysis.The study has statistically confirmed three out of eight hypotheses. The three hypotheses show that when the number of economic operators in the supply chain increases and also imbalances in the sales channels increase. Additionally, the imbalance of power in the sales channels has a negative effect on economic sustainability, and external barriers have a negative effect on the imbalance of power in the sales channels. The interviews supported seven of the hypotheses, although four of them were not supported.The empirical evidence presented in this study indicates that the lack of balance within the supply chain exerts a substantial influence on the economic sustainability of local food producers. By adopting a comprehensive approach, this research demonstrates that a more holistic perspective leads to enhanced economic sustainability. Additionally, it elucidates the diverse ways in which various factors impact the economic sustainability of local food produce.

We need landscape-scale approaches to design and manage agro-ecosystems that can sustain both agricultural production and biodiversity conservation. In this study, yield figures provided by 299 farmers served to quantify the energy-equivalents of food production across different crops in 49 1-km2 landscapes. Our results show that the relationship between bird diversity and food energy production depends on the proportion of farmland within the landscape, with a negative correlation observed in agriculture dominated landscapes (≥ 64–74% farmland). In contrast, neither typical farmland birds nor butterflies showed any significant relationship with total food energy production. We conclude that in European temperate regions consisting of small-scale, mixed farming systems (arable and livestock production), productivity and biodiversity conservation may not be purely antagonistic, particularly when (semi-)natural habitats make up a large fraction of the landscape (≥ 20%).

There exists a noticeable gap between consumers' willingness to purchase green food and their actual purchase behavior. However, the awareness of green development is a crucial factor influencing this purchase behavior and acts as an internal driving force promoting green consumption. Consumers' green development awareness is shaped by various psychological motivations, including environmental concern, health consciousness, knowledge, norms, and price considerations. The existing literature often focuses on specific regions or groups, lacking comprehensive cross-regional and multivariate evaluations, and frequently overlooks the potential impact of moderating variables such as economic development level, product type, and behavior type.To clarify the overall effect of each motivational factor on green food purchase behavior, this study conducted a meta-analysis. We selected eight causal variables and three moderating variables that significantly influence consumers' green food purchase behavior. The analysis included 132 independent effect values from 45 research papers.The meta-analysis revealed that: Consumers' green food purchase behavior is significantly positively correlated with eight motivational factors: environmental awareness, health awareness, green attitude, green knowledge, subjective norms, price awareness, perceived behavior control, and perceived usefulness. Economic development level, product type, and behavior type significantly affect consumers' green food purchase behavior. The impact of motivational factors on actual purchase behavior is weaker than on purchase intention, suggesting that interventions should focus on converting purchase intentions into actual purchase behavior. The findings indicate that environmental responsibility, government policies, and marketing strategies can influence consumers' psychological motives, guiding them toward more responsible consumption choices.Enhancing consumers' environmental and health awareness is essential, and policy support and marketing strategies can effectively promote green food consumption. These insights underscore the importance of targeted interventions to bridge the gap between green purchase intention and behavior.

Agriculture is crucial for the economy and individuals, and there is a pressing need to improve its quality, efficiency, and competitiveness in emerging countries. This study uses data from Chinese-listed companies to investigate the effect of trade credit on agricultural firms’ total factor productivity. The results demonstrate that trade credit access and provision can increase agribusinesses’ total factor productivity. Heterogeneity analysis reveals that access to business credit has a higher contribution to total factor productivity for agribusinesses in the primary sector, for firms in the versus maturity stage, and with low or medium supplier concentration. The provision of trade credit has a more pronounced positive impact on agribusinesses in the maturing stage and enterprises with low or medium customer concentration. This paper further validates the channels of action through which trade credit affects a firm’s high-quality development. This research makes a valuable contribution to enhancing the quality and productivity of China’s agricultural sector.

There is an ongoing debate regarding the role of international trade on food security and food sovereignty. While food security is a concept with a recognized definition and methodologies to assess it, food sovereignty has multiple definitions, and it is not clear how to measure it. Our purpose is to analyze the evolution of cherry and avocado domestic purchases as an illustrative example of the role of international trade on food security and food sovereignty.Using a descriptive analysis, we analyse export data at country level and household data representative of urban centers.We found that cherry and avocado exports have increased over the last decades. We found that domestic cherry and avocado purchases have been stable, while the overall fruit and vegetable purchases have been decreasing. Besides, the cherry seasons are showing some signs of expansion. In terms of disparities, households from quintiles 1 and 2, the two lowest income quintiles, increased cherry purchases. Moreover, households from quintiles 4 and 5, the two highest income quintiles, decreased cherry purchases.International trade can also help to increase domestic purchases and decrease purchases disparities, which can be linked to food access and food security. However, the increased of off-season imports of avocado can be linked to a decreased food sovereignty. We expect to contribute to illustrate how international trade, food security and food sovereignty are linked, while the concept of food sovereignty keeps developing.

Efficient allocation of agricultural scientific and technological talents (ASTTs) is crucial for agricultural innovation and economic development. This study aims to systematically evaluate ASTTs’ allocation efficiency in provincial agricultural research institutions in China, aiding decision-making for local governments and research bodies. Utilizing data from 2009 to 2019 across 31 provinces, an output-oriented data envelopment analysis model measures ASTTs’ allocation efficiency and analyzes its trends, regional differences, and spatial characteristics. Results show: (1) Provincial ASTTs’ mean comprehensive technical efficiency (CTE) in China was 0.786, with room for improvement. (2) Enhanced CTE was driven by scale efficiency improvements, while pure technical efficiency declined, indicating a need for better management systems and technology applications. (3) Disparities in ASTTs’ allocation efficiency among provinces decreased, with higher efficiencies in the East and Central-Southern China regions. At the provincial level, areas like Jiangsu, Shandong, Henan, and Sichuan demonstrated relatively high ASTTs allocation efficiencies. (4) Spatial agglomeration of ASTTs’ allocation efficiency was localized in a few major agricultural provinces without a significant overall effect. These findings advocate for further optimization of ASTTs’ regional layout and management mechanisms in China.

There is a strong link between consumer behavior and healthy food consumption. However, how to narrow the gap between consumption intentions and actual healthy food consumption is still under discussion.This study takes Chinese families as the research object, based on the family participation in long-term care insurance (LTCI) policy, and constructs an analytical framework including healthy eating behavior, food consumption, and insurance system to discuss how to narrow the gap between consumption intention and actual healthy food consumption. In addition, the intermediary role played by the risk prevention mechanism is also analyzed. Based on data from the China Health and Nutrition Survey (CHNS), this study uses a difference-in-differences analysis framework to empirically examine the impact of changes in consumption behavior on healthy food consumption after households participate in the LTCI pilot.The research results show that implementing LTCI can increase the frequency of healthy meal preparation methods by 0.045 units and the frequency of not including processed foods in the meals of households participating in the policy by 0.033 units compared with households that do not participate. The daily meal quantity is increased by 0.198 (converted to 1.219 grams), and 0.198 units increase the healthy food consumption structure. This conclusion holds under a series of robustness tests. Mechanism test shows that LTCI affects healthy food consumption through risk prevention mechanisms. The impact of the LTCI policy will also not be affected by similar competitive policies. The heterogeneity test further proves that LTCI policies are more likely to increase healthy food consumption among urban households, larger households, and households employed in private enterprises. Based on these findings, it is recommended that families participate in LTCI to reduce the financial stress faced by families due to illness and care needs while increasing the demand for and consumption of healthy foods. The findings also provide a valuable reference for current policy formulation on improving family dietary quality in China.
{"title":"Consumer behavior and healthy food consumption: quasi-natural experimental evidence from Chinese household participation in long-term care insurance","authors":"Wenting Chen, Guangcheng Ma, Zhe Jia","doi":"10.3389/fsufs.2024.1364749","DOIUrl":"https://doi.org/10.3389/fsufs.2024.1364749","url":null,"abstract":"There is a strong link between consumer behavior and healthy food consumption. However, how to narrow the gap between consumption intentions and actual healthy food consumption is still under discussion.This study takes Chinese families as the research object, based on the family participation in long-term care insurance (LTCI) policy, and constructs an analytical framework including healthy eating behavior, food consumption, and insurance system to discuss how to narrow the gap between consumption intention and actual healthy food consumption. In addition, the intermediary role played by the risk prevention mechanism is also analyzed. Based on data from the China Health and Nutrition Survey (CHNS), this study uses a difference-in-differences analysis framework to empirically examine the impact of changes in consumption behavior on healthy food consumption after households participate in the LTCI pilot.The research results show that implementing LTCI can increase the frequency of healthy meal preparation methods by 0.045 units and the frequency of not including processed foods in the meals of households participating in the policy by 0.033 units compared with households that do not participate. The daily meal quantity is increased by 0.198 (converted to 1.219 grams), and 0.198 units increase the healthy food consumption structure. This conclusion holds under a series of robustness tests. Mechanism test shows that LTCI affects healthy food consumption through risk prevention mechanisms. The impact of the LTCI policy will also not be affected by similar competitive policies. The heterogeneity test further proves that LTCI policies are more likely to increase healthy food consumption among urban households, larger households, and households employed in private enterprises. Based on these findings, it is recommended that families participate in LTCI to reduce the financial stress faced by families due to illness and care needs while increasing the demand for and consumption of healthy foods. The findings also provide a valuable reference for current policy formulation on improving family dietary quality in China.","PeriodicalId":504481,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"18 S2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141383562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aimed to extract polyphenolic compounds from lucuma (Pouteria lucuma) seeds using natural deep eutectic solvents (NADES) as a green, efficient, and environmentally friendly extraction. This was optimized by using the Response Surface Method (RSM) and comparing its predictive capacity with Artificial Neural Networks (ANN) and Convolutional Neural Networks (CNN). Four NADES were prepared by mixing lactic acid (LA) with each of the following reagents: sodium acetate (SA), urea (U), glucose (G), and ammonium acetate (AA), separately. The yield of total phenolic compounds (TPC) obtained from lucuma seeds with each NADES was measured as an optimization criterion with the Box-Benhken design. The following factors were evaluated: time, temperature, and the lucuma seed flour (LSF): NADES ratio. The response variables were TPC and antioxidant activity. The LA-AA extract was selected because it exhibited the highest TPC value and was analyzed by UHPLC–MS (Ultra-performance Liquid Chromatography-Mass Spectrometry). From the RSM, the optimal extraction parameters were 80 min, 52°C, and LSF: NADES ratio of 8:100 (w/v), obtaining a TPC value of 3601.51 ± 0.51 mg GAE/100 g LFS. UHPLC–MS analysis evidenced the formation of epigallocatechin isomers from epigallocatechin gallate. The predictive ability of ANNs compared to RSM was demonstrated.
