Purpose The choice of a sales channel for fresh vegetables is an important decision a farmer can make. Typically, the farmers rely on their personal experience in directing the produce to a sales channel. This study examines how sales forecasting of fresh vegetables along multiple channels enables marginal and small-scale farmers to maximize their revenue by proportionately allocating the produce considering their short shelf life. Design/methodology/approach Machine learning models, namely long short-term memory (LSTM), convolution neural network (CNN) and traditional methods such as autoregressive integrated moving average (ARIMA) and weighted moving average (WMA) are developed and tested for demand forecasting of vegetables through three different channels, namely direct (Jaivasree), regulated (World market) and cooperative (Horticorp). Findings The results show that machine learning methods (LSTM/CNN) provide better forecasts for regulated (World market) and cooperative (Horticorp) channels, while traditional moving average yields a better result for direct (Jaivasree) channel where the sales volume is less as compared to the remaining two channels. Research limitations/implications The price of vegetables is not considered as the government sets the base price for the vegetables. Originality/value The existing literature lacks models and approaches to predict the sales of fresh vegetables for marginal and small-scale farmers of developing economies like India. In this research, the authors forecast the sales of commonly used fresh vegetables for small-scale farmers of Kerala in India based on a set of 130 weekly time series data obtained from the Kerala Horticorp.
生鲜蔬菜销售渠道的选择是农民可以做出的重要决策。通常情况下,农民依靠他们的个人经验来引导农产品进入销售渠道。本研究考察了沿多个渠道的新鲜蔬菜销售预测如何使边际和小规模农民通过考虑其短保质期的产品按比例分配来最大化其收入。设计/方法/方法机器学习模型,即长短期记忆(LSTM),卷积神经网络(CNN)和传统方法,如自回归综合移动平均(ARIMA)和加权移动平均(WMA)通过三个不同的渠道开发和测试蔬菜需求预测,即直接(Jaivasree),调节(世界市场)和合作(Horticorp)。结果表明,机器学习方法(LSTM/CNN)为监管(World market)和合作(Horticorp)渠道提供了更好的预测,而传统的移动平均线对直接(Jaivasree)渠道产生了更好的结果,因为与其他两个渠道相比,直接(Jaivasree)渠道的销量较少。研究限制/启示由于政府设定了蔬菜的基本价格,因此不考虑蔬菜的价格。现有文献缺乏模型和方法来预测像印度这样的发展中经济体的边缘和小规模农民的新鲜蔬菜销售。在这项研究中,作者根据从喀拉拉邦园艺公司获得的一组130周的时间序列数据,预测了印度喀拉拉邦小农常用新鲜蔬菜的销售。

Purpose This paper aims to analyze relative contribution of intensive margin (IM) and extensive margin (EM) to growth in India's agricultural exports for the period 2001 to 2020. It also analyses the determinants of IM and EMs through a standard gravity model. Design/methodology/approach The study uses export data from United Nations Comtrade, which is accessed through World Integrated Trade Solution (WITS) software. Data for the period 2001 to 2020 were compiled for analysis using the Harmonized System (HS) of commodity classification system at the six-digit level. This study decomposed the contribution of IM and EM in the growth of Indian agricultural trade by using Hummels and Klenow's approach. After performing the export decomposition analysis, the authors analyze the factors influencing IM and EM by using the Tobit regression model and Poisson pseudo-maximum-likelihood (PPML) method of estimation. Findings The EM grew at 1.24% per annum, while the intensive margin (IM) increased by 0.23%. The contribution of growth at the EM increased from 58.8% in 2001 to 70.2% in 2020. Export growth along the IM was relatively high for animal products and agricultural raw materials, while growth at the EM was an important contributor to the export growth of horticultural and processed agricultural products. There was a positive and significant effect of the free trade agreement (FTA) on export margins. Research limitations/implications More disaggregated commodity-specific studies on value chain analysis would provide valuable insights into the issues hindering exports and realizing the untapped export potential. Originality/value There is a scarcity of holistic and recent studies illustrating the role of IM and EMs in agricultural trade growth, covering a large number of commodities and geographies associated with Indian agricultural trade. The study would be helpful to the stakeholders in facilitating informed policy decisions.
本文旨在分析2001年至2020年期间印度农业出口增长的集约边际(IM)和广泛边际(EM)的相对贡献。本文还通过一个标准的引力模型分析了电磁干扰和电磁干扰的决定因素。设计/方法/方法本研究使用联合国商品贸易统计的出口数据,可通过世界综合贸易解决方案(WITS)软件获取。2001年至2020年的数据是以六位数的商品分类协调制度(Harmonized System)进行分析。本研究采用Hummels和Klenow的方法分解了进出口贸易和新兴市场对印度农业贸易增长的贡献。在进行出口分解分析的基础上,采用Tobit回归模型和泊松伪极大似然(PPML)估计方法,分析了进出口贸易和出口贸易的影响因素。EM以每年1.24%的速度增长,而IM以每年0.23%的速度增长。新兴市场对经济增长的贡献由2001年的58.8%上升至2020年的70.2%。动物产品和农业原材料的出口增长相对较高,而新兴市场的增长对园艺和加工农产品的出口增长作出了重要贡献。自由贸易协定(FTA)对出口利润率有显著的正向影响。研究局限/影响对价值链分析进行更多的具体商品分类研究将对阻碍出口和实现未开发出口潜力的问题提供有价值的见解。缺乏整体的和最近的研究来说明新兴市场和新兴市场在农业贸易增长中的作用,这些研究涵盖了与印度农业贸易相关的大量商品和地区。这项研究将有助于利益相关者促进知情的政策决定。

Purpose This study investigates the supply chain efficiency of selected companies in the Indian food processing sector. Additionally, it explores the relationship between supply chain efficiency and firm performance. Design/methodology/approach To determine the supply chain efficiency, the study uses supply chain efficiency measures, such as supply chain length, inefficiency ratio and working capital productivity. Secondary data were collected from the Center for Monitoring Indian Economy (CMIE) Prowess database for the years 2011–2017. Various return measures, such as Return on Net Worth (RONW), Return on Total Assets (ROTA) and Return on Capital Employed (ROCE), were used to measure firm performance. Collected data were analyzed to investigate the relationship between supply chain efficiency and firm performance. Findings Findings of the study reveal the prevalence of inefficient supply chains in the context of the selected companies. There is a significant negative correlation between supply chain efficiency and firm performance. RONW has a significant negative correlation with the length of supply chain as well as supply chain inefficiency. Research limitations/implications This study expands the limited existing research perspective; the study helps to understand the supply chain efficiency and firm performance. Originality/value This is an original piece of work and provides valuable insight into the relationship between supply chain efficiency and firm performance.
本研究调查了印度食品加工部门选定公司的供应链效率。此外,它探讨了供应链效率和企业绩效之间的关系。为了确定供应链效率,本研究使用供应链效率措施,如供应链长度、低效率比和营运资本生产率。二级数据收集自2011-2017年印度经济监测中心(CMIE)实力数据库。各种回报措施,如净资产回报率(RONW),总资产回报率(ROTA)和资本使用回报率(ROCE),被用来衡量企业绩效。对收集的数据进行分析,以调查供应链效率与企业绩效之间的关系。研究结果揭示了所选公司背景下低效供应链的普遍存在。供应链效率与企业绩效呈显著负相关。RONW与供应链长度、供应链效率低下呈显著负相关。本研究拓展了有限的现有研究视角;该研究有助于理解供应链效率与企业绩效之间的关系。这是一篇原创的作品,为供应链效率和企业绩效之间的关系提供了有价值的见解。

Purpose This paper aims to assess the determinants of food certificate adoption and analyse the impacts of food certificates on e-commerce income among small online agri-food sellers in Indonesia. Design/methodology/approach The authors used data from an online survey of 228 small-online agri-food sellers in East Java, Indonesia. This study aims to focus on two food certificates: a mandatory Halal (Islamic dietary law) certificate and the P-IRT certificate, a food safety certificate for home-based businesses. A maximum simulated likelihood (MSL) estimator was employed to account for selection bias and endogeneity. Findings The study highlights the continued importance of certification in agri-food markets, including e-commerce and the need to consider the degree of substitutability and resource allocation between multiple food certificates. It finds that online agri-food sellers adopting the Halal certificate earn two to three times higher compared to non-adopters. Conversely, the gross income per month from e-commerce sales is 78% lower among those adopting the P-IRT certificate. Moreover, access to regulatory information sources motivates the likelihood of adopting food certificates. In contrast, the business size, marketing channels, contractual relationship and management capabilities are insignificant factors for the adoption of any of the Halal and P-IRT certificate combinations. Research limitations/implications Results from this research might be specific to the context of the focus study area, thereby reducing their generalisability. In addition to gathering representative samples, future research should also capture more complex dimensions of food certificates. These include the cost of acquiring food certificates, online sellers' perceptions of food certificate adoption, and emerging topics such as group certification and the use of technology. Originality/value To the authors' knowledge, this research is one of the first studies investigating the adoption of food certificates within the e-commerce setting. This study also contributes to the small number of studies looking at multiple certificate adoption and food certificate issues from the retailers' perspectives
本文旨在评估食品证书采用的决定因素,并分析食品证书对印度尼西亚小型在线农业食品销售商电子商务收入的影响。设计/方法/方法作者使用了对印度尼西亚东爪哇228个小型在线农业食品销售商的在线调查数据。本研究的重点是两种食品证书:强制性的Halal(伊斯兰饮食法)证书和P-IRT证书,即家庭企业的食品安全证书。使用最大模拟似然(MSL)估计器来解释选择偏差和内生性。该研究强调了认证在农产品市场(包括电子商务)中的持续重要性,以及考虑多种食品证书之间的可替代性和资源分配程度的必要性。研究发现,采用清真认证的在线农产品卖家的收入是不采用清真认证的卖家的两到三倍。相反,采用P-IRT证书的人每月电子商务销售总收入低78%。此外,获取监管信息来源可以提高采用食品证书的可能性。相比之下,企业规模、营销渠道、合同关系和管理能力是采用任何清真和P-IRT证书组合的无关紧要的因素。研究局限性/启示本研究的结果可能特定于重点研究领域的背景,从而降低了其普遍性。除了收集有代表性的样本外,未来的研究还应该捕捉食品证书更复杂的维度。其中包括获得食品证书的成本、在线卖家对食品证书采用的看法,以及团体认证和技术使用等新兴话题。原创性/价值据作者所知,这项研究是首批调查电子商务环境中食品证书采用情况的研究之一。本研究也有助于从零售商的角度看待多重证书采用和食品证书问题的少数研究

PurposeMaize and rice constitute the two major staple crops in Ghana. The demand for maize and rice outstrips production levels in Ghana, creating deficits for farmers to capitalize on to increase yield. Farmers procure certified seeds from different supply outlets to improve crop yield. This study assessed the effectiveness of supply outlets of certified maize and rice seeds. This study also examined factors that influence smallholder farmers' decisions in sourcing seed from the identified supply outlets.Design/methodology/approachMulti-stage sampling was used to collect data from smallholder farmers. A total of 360 farmers were interviewed for the analysis. The multivariate probit model was used to estimate the main drivers of the supply outlets of certified seeds.FindingsThe findings revealed that farmers' decisions to use certified seeds from a particular supply outlet are contingent on household size, years of farming, extension contacts, distance to the nearest market, distance to the district capital, access to credit and farm size.Research limitations/implicationsSourcing certified seeds from National Seed Traders Association of Ghana, Research Institutions and Ministry of Food and Agriculture is more effective than input dealers, open market and family and friends.Originality/valueThis study is one of its kind that looked at how effective are the supply outlets of certified seed purchasing outlets.
目的玉米和水稻是加纳的两大主要作物。加纳对玉米和水稻的需求超过了生产水平,为农民增加产量创造了赤字。农民从不同的供应渠道采购经过认证的种子,以提高作物产量。这项研究评估了经认证的玉米和水稻种子供应渠道的有效性。这项研究还考察了影响小农户从确定的供应渠道采购种子的因素。设计/方法/方法多阶段抽样用于收集小农户的数据。共采访了360名农民进行分析。多元probit模型用于估计认证种子供应渠道的主要驱动因素。调查结果显示,农民使用特定供应渠道认证种子的决定取决于家庭规模、耕种年限、推广联系、与最近市场的距离、与地区首府的距离、获得信贷的机会和农场规模。研究限制/影响从加纳国家种子贸易商协会、研究机构和食品和农业部采购认证种子比投入经销商、公开市场和家人朋友更有效。原创性/价值这项研究是同类研究中的一项,着眼于认证种子采购网点的供应网点的有效性。

PurposeThis study evaluated the use of Internet-mediated platforms for food supply chain among Ukrainian farmers due to the war.Design/methodology/approachThe study was an online survey involving 325 Ukrainian farmers. The instrument for data collection was a structured questionnaire.FindingsThe result of the study revealed the main effect of Internet-powered media such as social media, mobile applications and dedicated websites on food supply, F(1,308) 5.745, p = 0.004, p2 = 0.036. The result also revealed the interacting effect of supply intention (p = 0.001) and destination of supply (p = 0.001). Further analysis revealed that farmers with profit and charity intentions are likely to use dedicated websites, while those with trade-by-batter intentions are likely to use mobile applications. Also, the supply destination significantly interacted with the use of Internet-powered technologies (p = 0.001). A breakdown of the result showed that supply destinations in Ukraine are likely to be coordinated through dedicated websites, while those for neighbouring countries are likely to be coordinated through social media. Finally, variables from the unified theory of technology acceptance and use of technology, such as effort expectancy (ß = 0.412), performance expectancy (ß = 0.655) and social influence (ß = 0.182), collectively and individually predict the use of Internet-powered communication technologies for food supply among Ukrainian farmers, F(3,308)16.801, p = 0.001, R2 = 0.142.Research limitations/implicationsThis study explains how Internet-based media have contributed to the sustenance of agribusiness and food supply chain in challenging times like war.Originality/valueInformation from this study could be useful in understanding the contributing role of digital media in agribusiness and food supply during uncertainties.
目的:本研究评估了乌克兰农民因战争而使用互联网为媒介的食品供应链平台。设计/方法/方法该研究是一项涉及325名乌克兰农民的在线调查。数据收集的工具是一份结构化的问卷。研究结果显示,社交媒体、移动应用程序和专用网站等互联网媒体对食品供应的主要影响为F(1,308) 5.745, p = 0.004, p2 = 0.036。供给意向(p = 0.001)与供给目的地(p = 0.001)之间存在交互作用。进一步的分析显示,以盈利和慈善为目的的农民可能会使用专门的网站,而那些以贸易为目的的农民可能会使用移动应用程序。此外,供应目的地与互联网技术的使用显著相互作用(p = 0.001)。对结果的分析显示,乌克兰的供应目的地可能通过专门的网站进行协调,而邻国的供应目的地可能通过社交媒体进行协调。最后,来自技术接受和技术使用统一理论的变量,如努力预期(ß = 0.412)、绩效预期(ß = 0.655)和社会影响(ß = 0.182),共同和单独预测了乌克兰农民在粮食供应中使用互联网通信技术的情况,F(3,308)16.801, p = 0.001, R2 = 0.142。本研究解释了基于互联网的媒体如何在战争等具有挑战性的时期为农业综合企业和食品供应链的维持做出贡献。原创性/价值本研究的信息有助于理解数字媒体在不确定时期对农业综合企业和食品供应的贡献作用。

PurposeThe agricultural extension system in Indonesia has experienced its ups and downs in line with the sociopolitical dynamics of the country. This study examines the impact of access to agricultural extension on the adoption of technology and farm income of smallholder farmers in Banten, Indonesia.Design/methodology/approachThis study uses a quasi-experimental research design to estimate the impact outcomes at the farm level, with methods that form part of the counterfactual framework.FindingsEstimation results show that farming experience, off-farm income, irrigation, group membership, mobile phones and livestock ownership significantly affect extension access. The results of this main study show the important role of extension access to technology adoption and agricultural income. These studies found consistently positive and statistically significant effects of access to extension services on technology adoption and farm income.Research limitations/implicationsThe consistent positive and significant effect of extension access implies that public investment by the government in agricultural extension can optimize the potential impact on technology adoption and agricultural income, which also affects the distribution of the welfare of rural smallholder farmers.Originality/valueAgricultural extension as a key to increasing technology adoption. However, the impact of access to agricultural extension in Indonesia has received less attention in terms of adoption and farm income.
目的印尼的农业推广系统经历了与该国社会政治动态相一致的起伏。本研究考察了获得农业推广对印度尼西亚万丹小农户采用技术和农业收入的影响。设计/方法论/方法本研究使用准实验研究设计来估计农场层面的影响结果,方法构成反事实框架的一部分。FindingsEstimation结果显示,农业经验、非农收入、灌溉、团体会员、手机和牲畜所有权显著影响推广准入。这项主要研究的结果表明,推广获取技术对技术采用和农业收入的重要作用。这些研究发现,获得推广服务对技术采用和农业收入的影响始终是积极的,具有统计学意义。研究局限性/含义推广准入的持续积极和显著影响意味着政府对农业推广的公共投资可以优化对技术采用和农业收入的潜在影响,这也会影响农村小农户的福利分配。独创性/价值农业推广是提高技术采用率的关键。然而,在收养和农业收入方面,印度尼西亚获得农业推广的影响较少受到关注。

PurposeDue to the recent disruptions caused by COVID-19, global supply chains are stress tested. The affected supply chains have interfered with market tonnage prices for the yield of perishable products like mangoes that are highly dependent on their quality. This research, through empirical findings, thus determines and comprehends the factors influencing mango quality (size).Design/methodology/approachA framework is developed for finding the potential factors of quality building on the previous literature and studies on the available topic. The data collection included face-to-face interviews comprising 240 farmers, hired managers and preharvest contractors in India's Jangaon, Rangareddy and Yadadri Bhuvanagiri districts of Telangana state. The data analysis is done using multiple regression, and the outcomes form the basis of the design of the experiments model.FindingsThe empirical insights support that the quality of mango is affected by factors such as the number of picking cycles, the cost of fertilizer, the variety of fertilizers used, the variety of pesticides used and pesticide application frequency. The direct implications are the benefit to farmers in improving mango quality and maximizing profit per yield cycle.Research limitations/implicationsTo the best of the authors’ knowledge, the first research that has specifically focused on holistically improving the quality(size) of mangoes.Originality/valueThe findings contribute to the perishable supply chain literature, specifically to the mango study, to comprehensively showcase the factors impacting the quality of mangoes and provide guidance to farmers regarding orchard practices.
目的由于最近新冠肺炎造成的中断,全球供应链面临压力测试。受影响的供应链干扰了芒果等易腐产品的市场吨位价格,这些产品的产量高度依赖于其质量。本研究通过实证研究,从而确定和理解影响芒果质量(大小)的因素。设计/方法论/方法在现有文献和研究的基础上,开发了一个框架来寻找潜在的质量因素。数据收集包括面对面采访,采访对象包括印度特伦甘纳州詹冈、兰加雷迪和亚达德里-布瓦纳吉里地区的240名农民、雇佣的经理和采前承包商。数据分析使用多元回归进行,结果形成了实验模型设计的基础。研究结果实证结果表明,芒果的品质受采摘周期数、肥料成本、使用的肥料种类、使用的农药种类和农药施用频率等因素的影响。直接影响是农民在提高芒果质量和每个产量周期利润最大化方面的利益。研究局限性/含义据作者所知,这是第一项专门致力于全面提高芒果质量(大小)的研究。原创性/价值这些发现有助于易腐供应链文献,特别是芒果研究,全面展示影响芒果质量的因素,并为农民提供果园实践方面的指导。

PurposeThis paper finds the returns from soil conservation practices and examines whether the welfare implications of adopting the conservation practices are heterogeneous across the farming groups in Indian agriculture.Design/methodology/approachThe study uses an endogenous switching regression (ESR) method on the data collected from the 77th round of National Sample Survey (2019–21) to quantify the returns from adopting soil conservation practices.FindingsIt finds that farmers adopting soil health conservation practices would have reduced their crop yield by 13% if they did not implement them. Similarly, smallholders who have not adopted soil health management practices would have increased crop yield by 16% if they had adopted the practices. The authors also observed that the returns from adopting soil health management practices vary across farming groups, where marginal and large farms tend to gain higher yields. Finally, the authors find that regardless of farm size, smallholders who did not adopt soil health management practices would benefit from adopting these with increased crop yields of 29%–31%.Research limitations/implicationsMore data could have been better for drawing policy implications, since the number of soil card users are relatively less.Originality/valueThis research work uses nationally representative data, which is first in nature on this very aspect.
目的本文发现了土壤保护实践的回报,并考察了在印度农业中,采用土壤保护实践对福利的影响是否是异质的。设计/方法/方法该研究对第77轮全国抽样调查(2019-21)收集的数据使用内生切换回归(ESR)方法来量化采用土壤保持措施的回报。研究发现,如果农民不实施土壤健康保护措施,他们的作物产量将减少13%。同样,如果没有采用土壤健康管理做法的小农户采用了这些做法,他们的作物产量将增加16%。作者还观察到,采用土壤健康管理做法的回报因农业群体而异,边缘和大型农场往往获得更高的产量。最后,作者发现,无论农场规模如何,不采用土壤健康管理方法的小农户都将从中受益,作物产量将提高29%-31%。研究局限性/含义更多的数据本可以更好地绘制政策含义,因为土壤卡用户的数量相对较少。独创性/价值这项研究工作使用了具有全国代表性的数据,这在这方面是第一次。

PurposePoor post-harvest handling practices by seaweed farmers are a key issue in seaweed value chains, contributing to low-quality seaweed being supplied to processors. To address this, a range of advanced drying technologies and methods have been developed, yet uptake by farmers remains low. This study examines factors affecting drying technology uptake by seaweed farmers to identify opportunities to incentivise improved drying practices.Design/methodology/approachThis study draws on a quantitative survey of 273 seaweed farmers in two villages in South Sulawesi, 16 months of ethnographic fieldwork and 166 semi-structured interviews.FindingsFarmers engage in limited adoption of improved drying technologies and practices as they don't receive higher prices for higher quality products, instead aiming to meet only the minimum acceptable standards to avoid a price discount or rejection of their product. Technologies and techniques that have been adopted are often used in ways that differ from their original purpose, such as to reduce drying times and labour input, rather than to produce products of low moisture and dirt contents. Similarly, local traders mix high- and low-quality seaweed in order to supply warehouses with seaweed which on average meets minimum quality standards.Originality/valueThis study reveals that improved drying practices are unlikely to be adopted unless incentivised by more targeted price-grade differentials.
目的海藻养殖户收割后处理不当是海藻价值链中的一个关键问题,导致向加工商供应低质量海藻。为了解决这一问题,已经开发了一系列先进的干燥技术和方法,但农民的接受率仍然很低。这项研究考察了影响海藻养殖户采用干燥技术的因素,以确定激励改进干燥做法的机会。设计/方法/方法本研究采用了对南苏拉威西两个村庄273名海藻养殖户的定量调查、16个月的民族志实地调查和166次半结构化访谈。发现农民有限地采用改进的干燥技术和做法,因为他们的产品质量更高,价格不会更高,而是只达到最低可接受的标准,以避免价格折扣或拒绝他们的产品。所采用的技术和技术往往以不同于其最初目的的方式使用,例如减少干燥时间和劳动力投入,而不是生产低水分和低污垢含量的产品。同样,当地贸易商将高质量和低质量的海藻混合在一起,为仓库供应平均符合最低质量标准的海藻。独创性/价值这项研究表明,除非受到更有针对性的价格等级差异的激励,否则不太可能采用改进的干燥方法。
