Impacts of a saline water control project on aquaculture livelihoods in the Vietnamese Mekong Delta

PurposeDrought and salinity intrusion aggravated by climate change threaten agricultural livelihoods in Viet Nan's Mekong Delta. In response, authorities have built water management infrastructure for irrigation and salinity protection. This study assessed the impact of one such project, the Ba Lai dam in Ben Tre province, on the livelihoods of aquaculture farmers.Design/methodology/approachThis study uses the Sustainable Livelihoods Framework to assess the impact of the Ba Lai dam on the livelihood capitals of 18 farming households in four communes, located both upstream and downstream of the dam.FindingsThe authors find that, apart from some positive effects, the dam has also brought negative environmental consequences, such as increased water pollution. The authors also find that farmers have responded to the changes by adapting their livelihood practices.Research limitations/implicationsThe samples were relatively small, encompassing four communes in Ben Tre province. On the other hand, this case study is instructive to the many ongoing infrastructure projects in the Vietnamese Mekong Delta.Social implicationsThe project have caused an increase in water-related social conflict.Originality/valueThe case of the Ba Lai dam provides a cautionary example for infrastructure-based water management plans, both in Viet Nam and more broadly. The study suggests the need to strengthen community participation and prioritize impacts of farmers' capital assets when constructing water management infrastructure for climate change adaptation.

Sustainability assessment of crops' production in India: empirical evidence from ARDL-ECM approach

PurposeThe study aims to evaluate the long- vs short-run relationships between crops' production (output) and crops' significant inputs such as land use, agricultural water use (AWU) and gross irrigated area in India during the period 1981–2018.Design/methodology/approachThe study applied the autoregressive distributed lag (ARDL) bounds testing approach to estimate the co-integration among the variables. The study uses the error correction model (ECM), which integrates the short-run dynamics with the long-run equilibrium.FindingsThe ARDL bounds test of co-integration confirms the strong evidence of the long-run relationship among the variables. Empirical results show the positive and significant relationship of crops' production with land use and gross irrigated area. The statistically significant error correction term (ECT) validates the speed of adjustment of the empirical models in the long-run.Research limitations/implicationsThe study suggests that the decision-makers must understand potential trade-offs between human needs and environmental impacts to ensure food for the growing population in India.Originality/valueFor a clear insight into the impact of climate change on crops' production, the current study incorporates the climate variables such as annual rainfall, maximum temperature and minimum temperature. Further, the study considered agro-chemicals, i.e. fertilizers and pesticides, concerning their negative impacts on increased agricultural production and the environment.

Impact of the COVID-19 lockdown on the economic situation and food security of rural households in India

PurposeThe purpose of the study is to understand what impact the first COVID-19 lockdown in 2020 had on the income and food security of rural households in India and whether it differed across socioeconomic factors. Moreover, the study assesses the needs of rural households and determines whether they had received adequate support services during the lockdown.Design/methodology/approachThe study adopted a repeated-measures quantitative survey design with 1,319 rural women from 16 states of India and conducted a telephonic survey.FindingsThe lockdown had directly impacted rural households' employment status and income but the impact differed depending on the type of employment. For example, working in a salaried job or on one's farm led to a lower likelihood of a complete decline in income in states other than Kerala as the lockdown continued. The study also revealed a change in the pattern of food consumption, with higher consumption of subsidized staple foods. It also became evident that the aid announced by the government reached the rural population with some delay.Research limitations/implicationsA limitation of the study was that many respondents refused to participate in phase 2, which reduced the sample size when comparing the two phases because the women did not own mobile phones. Instead, they were using their husbands' phones.Originality/valueThe study's findings can help better understand the needs of rural populations during crises, such as the COVID-19 pandemic. This can help to plan better and build preventive actions for such populations once their needs are understood. In addition, this can aid disadvantaged people for a minimal level of preparedness and security during such a crisis in the future.

Which food prices were more vulnerable to the COVID-19 blockade regulations in China? Comparison between perishable and storable vegetables

PurposeThis paper aims to investigate how differently the COVID-19 blockade regulations influence the prices of perishable and storable foods. The authors focus on the cases of the 2020 blockade at Hubei province and the 2021 blockade at Shijiazhuang city in China, and the authors examine how the blockade influenced the prices of Chinese cabbages (perishable) and potatoes (storable) within and around the blockade area.Design/methodology/approachThe paper employs the fixed effects model, the panel VAR (PVAR) model, and the spatial dynamic panel (SPD) model to estimate the impacts of the blockade on the food prices. It constructs the unique data set of 3-day average prices of Chinese cabbages and potatoes at main wholesale markets in China during the two urban blockade periods from January 1 to April 8 in 2020 and from January 1 to March 1 in 2021.FindingsThe results from the SPD models indicate that the price of Chinese cabbages was more vulnerable and increased by 7.1–9.8% due to the two blockades while the price of potatoes increased by 1.2–6.1%. The blockades also significantly influenced the prices in the areas adjacent to the blockade area. The SPD results demonstrate that the impacts of the blockades would be overestimated if the spatial dependence is not controlled for in the fixed effects model and the PVAR model.Research limitations/implicationsBecause the research focuses on the cases in China, the results may lack generalizability. Further research for other countries is encouraged.Originality/valueThis paper demonstrates the importance of considering food types and spatial dependence in examining the impact of the COVID-19 blockades on food prices.

Telephone farmers and an emerging ecosystem are unlocking the hidden middle of agricultural value chains in Kenya through innovation

PurposeThis article explores the potential of an emerging group of farmers in Kenya, namely the growing segment of urban-based medium-size farmers, often called “telephone farmers”. To what extent do they benefit from an emerging ecosystem to support them in operating their farms, and what does that mean for the Hidden middle of agricultural value chains, the actors between the farmers and consumers? Unlocking the potential production of telephone farmers will require more services from collectors, traders, transport firms, the storage facilities, wholesalers and processing units and retailers. Ultimately, optimized telephone farm production benefits the business of Hidden middle value chain actors, increases incomes and jobs and improves food security.Design/methodology/approachBased on a survey and in-depth interviews a profile of the telephone farmers is given and their role as innovators is analyzed. The Latia Resource Centre (LRC) provides assistance to medium-size farmers, like the telephone farmers, helping them to prepare business plans and use modern technology and contributing to an emerging ecosystem providing support to all farmers.FindingsThe article analyzes the medium-size telephone farmers. It documents the contributions of this new agricultural actor to developing value chains and a dynamic ecosystem. The paper profiles the telephone farmers first and then identifies what they need and the support they receive. The emerging innovative ecosystem impacts agricultural productivity and production and hence the development of value chains. Small farmers gain access to opportunities offered by telephone farmers, working for them as outgrower or farm worker.Research limitations/implicationsThe authors used a small sample of 51 farmers and covered only a two-year period.Social implicationsSmall farmers are being helped through the emerging eco-system and farm labor acquire skills, which they can also you on another or their own farm.Originality/valueBased on the analysis an even more effective ecosystem is suggested and policy recommendations are formulated before the conclusion is drawn that these medium-size farmers contribute to innovation diffusion, inclusive value chain development and food security and are becoming part of this expanding, innovative ecosystem. Following the debate on food security the results suggest to pay more attention to the development of telephone farmers given their role in developing agricultural value chains and innovative ecosystems.

Relational contracts and value chain governance: exporter approaches to overcoming transaction costs in Rwanda's coffee sector

Purpose In developing countries, local buyers often rely on relational contracting based on reciprocity and trust. This paper analyzes relational contracting and global value chain (GVC) governance by focusing on how domestic and foreign coffee exporters in Rwanda confront challenges.Design/methodology/approach Semi-structured interviews were conducted with 25 representatives of Rwandan private, Rwandan cooperative-owned and foreign exporters, and four coffee sector stakeholders.Findings Foreign firms export most Rwandan coffee, and local exporters express concerns about their ability to compete. Rwandan exporters face challenges accessing capital, competing with foreign firms and managing high transaction costs. They use relational contracts to reduce transaction costs, and they benefit from a monopsony zoning regulation that reduces competition. Foreign exporters face regulatory challenges: a government-set coffee price and the zoning regulation. They vertically integrate to reduce costs and lock in suppliers through prefinancing.Research limitations/implications Future research should analyze differences between local and foreign exporters in other contexts to advance understanding of the different challenges faced and contracting approaches used.Originality/value Few GVC governance studies address the role of relational contracts in contexts where enforcement is costly. Considering relational contracts within GVCs can improve value chain analysis, specifically in the developing countries where many GVCs start.

Accessing value-added market through cooperatives: a case study of Sitajakhala Dugdha Utpadak Samabai Samiti Ltd., India

PurposeMember-owned business organizations, such as cooperatives, are engaged in various economic activities that touch our everyday lives. Sitajakhala Dugdha Utpadak Samabai Samiti Limited (Sitajakhala Dairy Producers Cooperative Society Limited) is a successful cooperative society in the northeastern region of India. The purpose of this case study is to illustrate how the cooperative manages its production and supply chain of milk and milk products and highlights several issues that the cooperative encountered in the recent past and how those issues were managed. This case also illustrates how an agribusiness cooperative has been growing over the years, including expansion of business and the creation of a brand image, as well as benefiting its members and their communities.Design/methodology/approachThe authors used a case study approach where they went for in-person interviews of Sitajakhala's executive members and office staff; in addition, the authors were given access to Sitajakhala's marketing and financial records as well as its annual reports and vision documents.FindingsSitajakhala Co-op provides a platform where individual dairy farmers (most of who are small farmers and many of them are illiterate) can unite to bargain for higher prices for their milk. Due to its member-oriented business strategy, Sitajakhala Co-op has been growing well with active support of its members. Consistent quality control and marked improvements in labeling, bottling and packaging of milk and milk products has helped the cooperative to establish itself as a leader in dairy products supplier in Assam among bulk buyers as well as individual consumers. Sitajakhala cooperative also provides dairy farming related services to its members for free of charge to improve milk production and quality. One of the shortcomings of the cooperative is underutilization of its modern milk processing plant which needs to be addressed by the management in earnest.Research limitations/implicationsThis case study is based on information from one dairy cooperative in Assam, India; thus, the findings of this case may not translate into other dairy cooperatives in India or elsewhere. Nonetheless, cooperative practitioners may find the findings useful from a management perspective.Social implicationsSitajakhala Co-op management was keenly aware of the non-dairy related needs of the community it serves. Some of such services include free medical ambulance service for its members, supporting secondary education through providing merit and need-based scholarships and funding physical improvements to a local high school and a local college. In addition, the cooperative regularly provides funding to local sports and cultural events and local social institutions which have positive impact on the larger community. Sitajakhala cooperative has been providing employment to the local youth in the Morigaon area and plans on continuing to do so.Originality/valueTo the best of our knowledge, this is the first case study focusing on the management and operations of a dairy cooperative in the northeastern part of India. Knowledge gained from such study is expected to benefit not only Sitajakhala cooperative but also other dairy cooperatives in a similar situation. This case study will also benefit senior undergraduate and/or graduate students specializing in agricultural economics/agribusiness and can also be used for executive training for the management of academic institutions and food companies.

Financial feasibility assessment of adopting active controlled atmosphere containers for exporting highly perishable fruits during COVID-19: case of Taiwanese atemoya

PurposeThis study deals with attenuating the risk of relying on a single export market, which was heightened by the outbreak of the COVID-19 pandemic. It focuses on Taiwanese atemoya (a fruit with short storage life) and the adoption of active controlled atmosphere (CA) containers, a new technology which lengthens storage time for other export markets. This study looks at the financial feasibility of the technology's first ever use in atemoya exports.Design/methodology/approachApart from the standard financial assessment tools—like net present value (NPV), internal rate of return (IRR), benefit-cost ratio (BCR) and payback period (PBP)—this study calibrated five different scenarios based on data gathered from relevant market agents including suppliers, exporters, customs brokers and technology developer.FindingsDue to the high profit margin and low investment cost, the use of active CA containers for long-haul exports of this highly perishable fruit is found both technically and financially feasible, despite the generally higher operational cost during the pandemic.Research limitations/implicationsThis study looked at three specific export markets: Malaysia, Dubai and Canada. Results here may lack generalizability in other markets, although it is believed that slight deviations would not invalidate the conclusions of this research because short, medium and long distances were all covered therein.Originality/valueThis paper studies the first time that active CA is used for export of atemoyas to expand existing markets.

Artificial intelligence in agricultural value chain: review and future directions

PurposeThis paper is a literature review on use of artificial intelligence (AI) among agricultural value chain (AVC) actors, and it brings out gaps in research in this area and provides directions for future research.Design/methodology/approachThe authors systematically collected literature from several databases covering 25 years (1994–2020). They classified literature based on AVC actors present in different stages of AVC. The literature was analysed using Nvivo 12 (qualitative software) for descriptive and content analysis.FindingsFifty percent of the reviewed studies were empirical, and 35% were conceptual. The review showed that AI adoption in AVC could increase agriculture income, enhance competitiveness and reduce cost. Among the AVC stages, AI research related to agricultural processing and consumer sector was very low compared to input, production and quality testing. Most AVC actors widely used deep learning algorithm of artificial neural networks in various aspects such as water resource management, yield prediction, price/demand forecasting, energy efficiency, optimalization of fertilizer/pesticide usage, crop planning, personalized advisement and predicting consumer behaviour.Research limitations/implicationsThe authors have considered only AI in the AVC, AI use in any other sector and not related to value chain actors were not included in the study.Originality/valueEarlier studies focussed on AI use in specific areas and actors in the AVC such as inputs, farming, processing, distribution and so on. There were no studies focussed on the entire AVC and the use of AI. This review has filled that literature gap.

COVID-19 and agri-food value chain: a systematic review and bibliometric mapping

PurposeThe COVID-19 has had a diversified and dynamic impact on the food and agricultural sector, particularly in the agri-food value chain. Although a good number of articles were published in various countries and continents covering various aspects of the impact of COVID-19 on the agri-food value chain, no significant studies were found related to the mapping of published literature to know about the scenario and current trend research. The study aims to perform a systematic review and bibliographic mapping in the agri-food value chain to provide insights into the same.Design/methodology/approachArticles included in the Scopus database from January 1, 2020 to July 10, 2021 are considered. After initial screening and inclusion criteria, 41 articles have been selected to perform a systematic review which is published in the agri-food value chain. In addition to this, by considering the growth of the online food market, systematic mapping with the application of bibliometric analysis is performed to know the trend of the publications. Co-occurrence analysis with VOS viewer software version 1.6.16 is used for making network maps and supports the visualization of these maps.FindingsThe synthesis of the findings reveals that four broad themes recur in the articles: namely, food security and crisis during the pandemic, food price fluctuations, the impact of COVID-19 and disruption in the agri-food value chain and resilience strategies to strengthen the value chain. Alongside, the synthesis of the findings, this study describes the geographical coverage, methodologies used, sector/industry-specific context of the articles and scope of future research. In co-occurrence analysis with keywords, four clusters are identified related to the online food market and are categorized as “COVID-19 and Online food delivery services,” “Consumer satisfaction to online food delivery services,” “Food delivery system” and “Demographic impact on online food market.”Research limitations/implicationsThe study considers only the article from the Scopus database and article published between January 1, 2020 and July 10, 2021. Future studies are encouraged related to impact analysis studies of resilient strategies suggested by various authors by considering multiple databases.Originality/valueThis study will be beneficial for scholars and policymakers to know what is trending in the agri-food value chain and policymakers can implement various resilience strategies as discussed to mitigate the impact. The future research scope highlighted in this paper will encourage scholars and academicians to explore this area and will provide in-depth understanding.
