Vietnam rice value: Gravity model for transitional export period 2011-2021
Full text linkThis study examined the factors affecting Vietnam’s rice export value in the transitional period of 2011–2021 using panel data of 45 importers comprising 90% of Vietnam’s rice export value. The generalized least square model was used for estimation, and the results reveal that the factors of world rice export prices, importing country’s population, membership in the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, European–Vietnam Free Trade Agreement, and multilateral or bilateral relationship positively affect export value. However, the importing country’s GDP and self-produced food output and Vietnam’s inflation negatively influence rice export turnover. Consequently, several policy recommendations are suggested
Dominant business model consolidation processes: A System Dynamics-based analysis of the Prosecco wine industry
Full text linkProsecco wine has become one of the widest diffused sparkling wine with 627 million bottles produced in 2021 compared to 140 million bottles produced in 2010. The spread of the product is due to a rapid growth in production capacity that has allowed a large amount of product to be placed on the market at very competitive prices. The growth of the sector has led to a radical change in the characteristics of supply with the emergence of companies with a business model based on trading, not integrated in wine production, focused on bottling and selling the product. The paper analyzes, using a System Dynamics approach, the process that determined the affirmation of the trading business model by identifying the critical variables and the relevant feedback loops structures. Resource dynamic analysis allowed us to evaluate the long-term sustainability of the dominant business model
Latin American beer production and import demand for regional malt and malted barley
Full text linkOver the last 25 years, the Latin American beer sector has undergone important changes. The growth in beer production, consumption, and trade has been accompanied by a greater demand for malt and barley produced and traded in the region, displacing other traditional export countries of these inputs. Based on these facts, we studied the long-term relationship between this increase in beer production and the prices of imported inputs. In addition, we estimated the elasticities of demand of imported inputs of the main Latin American brewing countries. This allows us to infer about Latin America's competitive position as a supplier of its own beer inputs.
Policies nourishing sustainability: China's path to sustainable agri-food development
Full text linkOver the past two decades, China's remarkable economic growth has brought forth opportunities and challenges, including unsustainable food systems. Policies are pivotal in driving sustainable development, facilitating a balance between food supply, consumer demands, and environmental goals, thereby promoting a more sustainable food system. This study delves into the role of national policies from 2000 to 2022 in addressing these challenges, intending to reveal policy characteristics and potential impacts on agriculture and food. The research employs heat-map analysis, neural networks analysis, and topic analysis to explore policy concepts and themes, with findings underscoring the significance of rural development and food safety within agri-food policies. The presence of policy duplication and complementarity across different ministries provides valuable insights into the intricate dynamics of policy and their implications for sustainable agri-food systems in China and global sustainability endeavors
The performance analysis of the industrial tomato sector in Algeria: On the consequences of unfair prices
Full text linkThe aim of this study is to examine the structure of Algeria's industrial tomato sector, drawing lessons and highlighting the associated challenges. The study relies on comprehensive data, encompassing a substantial number of observations (up to 9 127) from the production and processing segments of the supply chain. The main findings reveal significant concentration within the processing segment (with a concentration index of 0.87 in 2021), indicating an oligopolistic market structure with limited competitive dynamics. Furthermore, the production segment displays a concerning trend of disengagement among producers, with a significant decline in their participation in the contracting process in recent years. The study also highlights weak contractual performance in the vertical relationship between the two segments, primarily due to unfair pricing practices. These findings collectively indicate an alarming situation for the entire sector. Consequently, this study provides some implications for public policy, suggesting the need for updated measures to address the current challenges
Should My Take-Away Packaging Be Reusable? An Empirical Study Of Consumer Behaviour Towards Returnable Food Packaging In Germany
Full text linkSince the new German packaging law 'VerpackG2' came into force in January 2023, German foodservice operators selling food to-go are required to provide reusable packaging alternatives to their single-use plastic food packaging. This change in legislation has led to the emergence of various reusable consumer packaging systems in the German market. Reusable packaging systems have the potential to significantly reduce the negative environmental impact of single-use plastic packaging. However, for these systems to be successful and achieve their desired positive environmental impact, also a comprehensive understanding of consumer behaviour towards these systems is needed. This study extends the Theory of Planned Behaviour (TPB) framework to identify the factors influencing consumers' intentions to use a reusable packaging system for takeaway food in the German foodservice industry. An online survey was developed and 153 valid responses were collected from consumers in Germany. Structural equation modelling revealed that consumers' personal moral norms, attitudes, subjective norms and perceived behavioural control directly influence consumers' intentions to use the reusable packaging system in this study. The results also show that context, motivation and personal moral norms are positively related to consumers' attitudes and that context has a significant positive effect on consumers' perceived behavioural control. Furthermore, the results of the study indicate that despite the high frequency of takeaway food orders in Germany, consumers' use of reusable packaging systems for takeaway food still needs to be improved
Vulnerability to resilience for smallholder, small grain farmers in Southern Zimbabwe: The case of semi-arid regions of Southern Zimbabwe
Full text linkSmall grain production provides hope for farmers in regions affected by climate change. This study determined the levels of smallholder, small grain farmers’ vulnerability and resilience using data collected from four districts (Binga, Chiredzi, Hwange and Matobo) in Zimbabwe’s agro-ecological regions 1V and V. A mixed method approach was used to collect data from 281 respondents. A multistage sampling approach with a purposive selection of districts dominant in small grain production was conducted. For each district, two wards were selected randomly. Stata version (16) was used to analyse the data. Factor analysis and Agricultural Drought Index (ADRI) were used to quantify farmer vulnerability and resilience. Results show that 46.3% were in the medium vulnerability group while 26% were highly vulnerable. Districts on contract farming were less vulnerable than districts on non-contract farming. Farmer resilience varied with location, with Chiredzi having the highest (ADRI 4.56) and Matobo the least (ADRI 3.32). The study made three recommendations; the production of improved small grain varieties in regions IV and V, the practice of conservation agriculture as an adaptation strategy to climate change and aggressive enforcement of agricultural policies relating to the production of small grain on contract farming
Combining process efficiency with process flexibility: The promise of artificial intelligence
Full text linkArtificial intelligence may not just provide information services but could also have a major impact on the organization of planning processes, adding higher levels of flexibility to efficiency. Apart from AI’s information services, the added value of flexibility may especially support processes that are confronted with high variabilities as, e.g. processes dealing with risk management and contingency planning
Comparative multidimensional analysis of agroforestry's impact on food security: A study of households in the Awi Zone Highlands, Ethiopia
Full text linkThis study assesses the food security condition of Acacia-based agroforestry (ABA) user and non-user households in Awi Zone highlands, Ethiopia, using a composite approach. Purposive and random samplings were employed to select sample districts and households. Data were collected through questionnaires, discussions, and interviews, and analyzed quantitatively and qualitatively. Results showed that 42.2% of the households (46.9% ABA-users, 37.5% non-users) were food-secure, while 57.8% were food-insecure. ABA-users’ composite food security index was significantly higher than non-users (P<0.05), signifying ABA's contributions. Livestock and farmland size, participation in off-farm activities, irrigation access, plantation experiences, and perceived soil quality positively affected food security, while age, family size, credit access, and market distance negatively impacted it. Addressing lavish sociocultural practices, and intensifying agroforestry helps to combat food insecurity
A supply chain resilience framework for pandemic disruptions in general trading companies
Full text linkIn general trading companies, COVID-19 pandemic disruptions impacted their supply chain performance and their business. The ability to respond effectively to pandemic disruptions using supply chain resilience framework is needed. This research proposed supply chain resilience framework for pandemic disruption in the general trading companies that is used to assess the relationship between pandemic disruptions and supply chain capabilities. This research employs an empirical approach with a qualitative research method using review literature, rigorous in-depth interview with 12 informants in 5 companies are founded pandemic disruption factors and supply chain capability factors. Indonesian general trading company was used as case study to determine probability value of pandemic disruptions factors, sub-dimension, and dimension using Bayesian Network approach and assess the relationship between pandemic disruption factors and supply chain capability factor. Top three pandemic disruptions factors based on Bayesian Network analysis are (1) meeting order, (2) customer visit, and (3) mobility. The assessment results of supply chain resilience framework in case study indicated that a vital factors of supply chain capability are (1) upscaling competency in absorptive capability, (2) internal and external collaborations and (3) financial management in adaptive capability. The practitioners can be better prioritizing supply chain capabilities for pandemic disruptions using this proposed supply chain resilience framework. This study also providing valuable insight for the managerial implication to understand government direction and promote communication and collaboration (internal and external) amongst their supplier and customers
