PurposeRice is an important grain in Indian scenarios, and the purpose of the research work is to identify the attributes which can be the possible barriers in the traditional rice supply chain network.Design/methodology/approachA multilevel conceptual model is developed based on the literature review, and a field study is conducted by administering a questionnaire from the experts. Fuzzy logic methodology and a ranking score method is applied to identify the rice supply chain performance and the barriers of the traditional rice supply chain network.FindingsThe rice supply chain performance index for the traditional rice supply chain network is obtained, and the performance of the existing rice supply chain is found to be “fair”. The “information flow” is the attribute that can be a critical weak attribute in the traditional rice supply chain network. A proposed model of the blockchain technology-enabled rice supply chain network is developed as a solution for the “information flow” barrier.Research limitations/implicationsThe present research work is focussed on the generalized rice supply chain model of the Indian scenario, and more detailed studies can be carried out based on the regional issues.Originality/valueThe rice supply chain plays an important role in Indian economic development, and hence the current research paper focusses on identifying the barriers and the performance of the existing rice supply chain network.
目的大米是印度情景中的一种重要谷物,研究工作的目的是确定传统大米供应链网络中可能存在的障碍。设计/方法/方法在文献综述的基础上开发了一个多层次的概念模型,并通过管理专家的问卷进行了实地研究。应用模糊逻辑方法和评分法对传统大米供应链网络的大米供应链绩效和障碍进行了识别。结果得到了传统大米供应链网络的大米供应链绩效指标,发现现有大米供应链的绩效是“公平的”。“信息流”是传统大米供应链网络中一个关键的薄弱属性。提出了一种基于区块链技术的大米供应链网络模型,作为“信息流”障碍的解决方案。研究局限性/含义目前的研究工作集中在印度情景的广义大米供应链模型上,可以基于区域问题进行更详细的研究。原创性/价值大米供应链在印度经济发展中发挥着重要作用,因此当前的研究论文侧重于识别现有大米供应链网络的障碍和性能。

PurposeThis paper analyzes the consumption of fruits and vegetables (FV) in Senegal by: (1) urban and rural areas; (2) FV types (African-indigenous vs non-indigenous); (3) sources of FV (imports, purchases and own-production).Design/methodology/approachThe authors undertake descriptive and regression analyses on consumption of FV sourced from purchases, own-production and gifts. The data come from primary surveys in 2017/2018 of 6,328 rural and urban households in Senegal.FindingsThe analysis showed that FV are important in urban and rural food consumption. A stunning 76% of rural FV consumption is from purchases, showing the importance of FV supply chains even into and among rural areas. Only 12% of national FV consumption is from imports. Most FV consumption in rural and urban areas is now of non-indigenous FV; African-indigenous FV have a minor share.Research limitations/implicationsA limitation of this paper is that it uses a cross-sectional dataset.Originality/valueThere are few national survey-based studies of FV consumption in Africa. This is the first to disaggregate FV consumption between primary versus secondary cities and rural towns, and rural areas close to and far from cities, in such detail regarding types and sources of FV as outlined in the findings. The regressions contribute by including determinants beyond income, including gender, employment, spatiality and education.
本文分析了塞内加尔水果和蔬菜(FV)的消费:(1)城市和农村地区;(2) FV类型(非洲本土vs非本土);(三)燃料来源(进口、采购和自产)。设计/方法/方法作者对来自购买、自产和礼品的FV消费进行了描述性和回归分析。这些数据来自2017/2018年对塞内加尔6328个农村和城市家庭的初步调查。研究结果分析表明,食品添加剂在城市和农村食品消费中都很重要。令人震惊的是,76%的农村燃料汽车消费来自购买,这表明燃料汽车供应链甚至进入农村地区和在农村地区之间的重要性。只有12%的国家燃料汽车消费来自进口。现在,农村和城市地区的大部分粮食消费是非土著粮食消费;非洲本土的FV只占很小的份额。研究限制/启示本文的一个限制是它使用了一个横截面数据集。原创性/价值非洲很少有基于国家调查的汽车消费研究。这是第一次对主要城市、次要城市和农村城镇以及靠近和远离城市的农村地区的FV消费进行分类,详细介绍了调查结果中概述的FV类型和来源。回归包括了收入以外的决定因素,包括性别、就业、空间和教育。

PurposeWith focus on Uganda, this study assessed the factors influencing agro-food micro, small and medium enterprises (MSME) innovations. Kampala, Wakiso, Mukono and Jinja districts were the locations of the research.Design/methodology/approachPrimary cross-sectional data was collected using structured questionnaire for a sample of 521 agro-food MSMEs in Uganda. Descriptive statistics, exploratory factor analysis and hierarchical regression analysis were used to examine the data in SPSS.FindingsThe findings indicate that MSME innovation levels were usually high, at roughly 80%. The presence of rules that encourage innovation and reward creative people would enhance innovation that is customer-focused. On the other hand, policies and principles that encourage innovation and the conduct of internal product and process improvement research would promote system-focused innovation.Research limitations/implicationsEncouraging agro-food MSMEs to develop policies that support innovation would improve the overall level of innovation, while building the capacity of agro-food MSMEs to conduct product and process improvement research would increase the level of systems-focused research.Originality/valueThis study assessed the drivers of innovation in agri-food MSMEs in a developing country. The uniqueness of this study is in assessing the effects of innovation support services on customer-focused and systems-focused innovations.
目的以乌干达为研究对象,评估影响农业食品中小微企业创新的因素。坎帕拉、瓦基索、穆科诺和金贾地区是这项研究的地点。设计/方法/方法采用结构化问卷收集了乌干达521家农业食品中小微企业样本的主要横截面数据。在SPSS中采用描述性统计、探索性因子分析和层次回归分析对数据进行检验。研究结果表明,中小微企业的创新水平通常很高,约为80%。鼓励创新和奖励有创造力的人的规则的存在将促进以客户为中心的创新。另一方面,鼓励创新和进行内部产品和过程改进研究的政策和原则将促进以系统为重点的创新。鼓励农业食品中小微企业制定支持创新的政策将提高整体创新水平,而建设农业食品中小微企业进行产品和工艺改进研究的能力将提高以系统为重点的研究水平。原创性/价值本研究评估了一个发展中国家农业食品中小微企业的创新驱动因素。本研究的独特之处在于评估创新支持服务对以客户为中心和以系统为中心的创新的影响。

Rural electrification and women's empowerment in Côte d’Ivoire Côte科特迪瓦的农村电气化和妇女赋权
IF 2.4 Q2 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2023-03-06 DOI: 10.1108/jadee-11-2021-0295

PurposeThis paper assesses the impact of this program on the rural women's employment opportunities using data from the 2015 round of the household's living standard survey (HLSS) of Côte d'Ivoire.Design/methodology/approachIn 2013, in order to improve the living conditions of the rural population, the Ivorian government launched the National Program for rural electrification (PRONER) to electrify all localities with more than 500 inhabitants.FindingsThe results show that PRONER, while reducing the time allocated to performing household chores, increases women's employment through the reallocation of time to full-time paid work in the agricultural and non-agricultural sectors. The authors also find that the allocation of men's time is not affected by this programme. A possible mechanism that would explain such a pro-women effect is the labour-saving technology introduced to home production as an effect of the reform.Research limitations/implicationsAs a limitation, it is important to note that these results were obtained in the specific context of PRONER in Côte d’Ivoire and are not necessarily applicable to rural electrification programmes in other contexts. Furthermore, the choice of other indicators to measure women's empowerment is limited by the quality of the data available. It would be interesting for future research to extend this analysis to include other aspects of women's empowerment and household welfare.Originality/valueThis paper is the first to the author’s knowledge to apply a robust econometric method by combining an inverse probability weighted regression adjustment model with Heckman sample selection method to access a robust causal effect of the PRONER in Côte d'Ivoire.
目的本文利用2015年科特迪瓦家庭生活水平调查(HLSS)的数据,评估了该计划对农村妇女就业机会的影响。设计/方法/方法2013年,为了改善农村人口的生活条件,科特迪瓦政府启动了全国农村电气化计划,为500多名居民的所有地区供电。结果表明,PRONER在减少分配给做家务的时间的同时,通过将时间重新分配给农业和非农业部门的全职带薪工作,增加了妇女的就业。作者还发现,男子的时间分配不受这一方案的影响。解释这种亲妇女效应的一个可能机制是,作为改革的一个影响,将节省劳动力的技术引入家庭生产。研究局限性/含义作为一个局限性,重要的是要注意,这些结果是在科特迪瓦PRONER的具体背景下获得的,不一定适用于其他背景下的农村电气化计划。此外,衡量妇女赋权的其他指标的选择也受到现有数据质量的限制。未来的研究将有兴趣将这一分析扩展到妇女赋权和家庭福利的其他方面。独创性/价值本文是作者所知的第一篇应用稳健计量经济学方法的论文,将逆概率加权回归调整模型与Heckman样本选择方法相结合,以获得科特迪瓦PRONER的稳健因果效应。

PurposeThe purpose of this study was to show how pro-gender public policies in the agricultural sectors can contribute to the reduction of gender inequalities in the labour market and the diversification of the Congolese economy.Design/methodology/approachComputable general equilibrium model that has been adapted to the Congolese economy from the Democratic Republic of the Congo (DRC)'s SAM.FindingsThe results reveal that policies of increasing women's land allocation and government cash transfers to rural female households contribute to the reduction of inequalities in the labour market. However, only the policy of increasing women’s land allocation improves economic diversification.Research limitations/implicationsThe implementation of the policy of government cash transfers to rural women's households comes at a cost to the government. Future studies to look at the most effective mode of financing for this policy. Moreover, the policy of increasing women's land allocation is feasible in the DRC as there is a lot of unused arable land available.Social implicationsIn Pillar 1 of the National Strategic Development Plan (PNSD) on Economic Diversification and Transformation, the policy of increasing land allocation to women could be added to the objectives related to strengthening the contribution of agriculture to economic growth and employment creation. In Pillar 3 of the PNSD on Social Development and Human Resource Development, the policy of increasing land allocation to women as well as the policy of increasing government transfers to female rural households could be added to the objectives related to the promotion of employment of youth, women and vulnerable groups.Originality/valueTo the best of the authors’ knowledge, this is the first study of its kind for the DRC, which highlights the impact of pro-gender policies on women's employment, particularly in the agricultural sectors and in the diversification of the Congolese economy. This study contributes to policy orientation in DRC. The two policies (increasing land allocation to women and cash transfers to rural women) analysed in this study were chosen in light of the DRC's National Strategic Plan, the first phase of which focuses on promoting employment for vulnerable groups and economic diversification through the development of agricultural sectors.
目的本研究的目的是显示农业部门的性别平等公共政策如何有助于减少劳动力市场中的性别不平等和刚果经济的多样化。设计/方法/方法可计算的一般均衡模型,已从刚果民主共和国(DRC)的SAM中适应刚果经济。研究结果表明,增加妇女土地分配和政府对农村女性家庭的现金转移的政策有助于减少劳动力市场的不平等。然而,只有增加妇女土地分配的政策才能促进经济多样化。研究局限/启示政府对农村妇女家庭的现金转移支付政策的实施使政府付出了代价。未来的研究将着眼于这一政策最有效的融资模式。此外,增加妇女土地分配的政策在刚果民主共和国是可行的,因为有大量未使用的可耕地。社会影响在国家战略发展计划关于经济多样化和转型的支柱1中,增加分配给妇女土地的政策可列入有关加强农业对经济增长和创造就业的贡献的目标。在《国家战略纲要》关于社会发展和人力资源开发的支柱3中,增加向妇女分配土地的政策以及增加政府向农村妇女家庭转移资金的政策可以列入与促进青年、妇女和脆弱群体就业有关的目标。原创性/价值据作者所知,这是刚果民主共和国的第一个此类研究,该研究强调了支持性别政策对妇女就业的影响,特别是在农业部门和刚果经济多样化方面。本研究有助于刚果民主共和国的政策导向。本研究分析的两项政策(增加对妇女的土地分配和向农村妇女的现金转移)是根据刚果民主共和国的国家战略计划选择的,该计划的第一阶段侧重于通过发展农业部门促进弱势群体的就业和经济多样化。

PurposeGhana's economy is largely agrarian, and the business of agriculture is dominated by smallholder farmers who are predominantly rural dwellers. As a result, efforts to lift rural farming households from poverty have been narrowed to the promotion of agricultural development to the neglect of the rural non-farm sector. However, this is fast changing in the advent of a burgeoning rural nonfarm economy and must engage the attention of policy actors. This study thus assesses the effect of non-farm participation on households' level of commercialization of agricultural crops in Ghana.Design/methodology/approachThe study applies a generalized structural equation model (GSEM) to the Ghana Living Standards Survey round 6 dataset, a stratified and nationally representative random sample of 16,772 households in 1,200 enumeration areas.FindingsThis study finds that non-farm participation increases the produce sold to output ratio. It is concluded that non-farm engagement by farmers boosts commercialization in Ghana. Thus, for the Ghanaian and similar contexts, agricultural development interventions that incorporate non-farm activities are more likely to be successful in improving livelihoods.Research limitations/implicationsThe study uses only the ratio of sales value to output value definition for commercialization and acknowledges use of multiple definitions could be superior.Originality/valueVarious empirical studies have examined the link between the farm and nonfarm sectors. This paper is original in its approach as it tackles an aspect of the subject that has been understudied, namely, an exploration of nonfarm and farm linkages from the perspective of agricultural commercialization.
加纳的经济以农业为主,农业业务主要由小农主导,他们主要是农村居民。其结果是,使农村农户摆脱贫困的努力被局限于促进农业发展,而忽视了农村非农业部门。然而,随着农村非农业经济的蓬勃发展,这种情况正在迅速改变,必须引起政策参与者的注意。因此,本研究评估了非农业参与对加纳农户农作物商业化水平的影响。本研究将广义结构方程模型(GSEM)应用于加纳生活水平调查第6轮数据集,该数据集是1200个枚举地区的16,772个家庭的分层和具有全国代表性的随机样本。本研究发现,非农业参与增加了产品的销售产出比。结论是,农民的非农业参与促进了加纳的商业化。因此,在加纳和类似的情况下,纳入非农业活动的农业发展干预措施更有可能成功地改善生计。研究局限/启示本研究仅使用销售价值与产出价值之比定义商业化,并承认使用多种定义可能会更好。各种实证研究都考察了农业和非农部门之间的联系。这篇论文的方法是原创的,因为它处理了这个问题的一个方面,这个方面一直没有得到充分的研究,即从农业商业化的角度探索非农和农场的联系。

PurposeThere is widespread belief that intermediaries in African agri-food value chains have disproportionate market power. In this paper, the authors examine this belief by uncovering the purchasing and selling prices, costs and profit margins by farmers, intermediaries and retailers in the matooke (cooking banana) value chain in Uganda, and by analysing the prevailing value chain and market structures, seasonal entry and exit dynamics and the trading relationships in the chain.Design/methodology/approachData for this study were collected along the trading routes from the main matooke producing districts in South-West Uganda (Kabarole, Bunyangabo, Bushenyi, Isingiro and Mbarara) to the main urban markets around the capital Kampala. A structured survey was administered with 383 producers, 172 collectors and wholesalers and 71 retailers. In addition, key informant interviews and focus group discussions were held.FindingsThe authors find that price mark-ups by intermediaries (selling prices minus purchasing prices) vary with the type of intermediary, season and location but generally reflect the costs of moving matooke down the value chain to the urban consumer. The authors do not find evidence for disproportionate market power among the intermediaries in the chain. Intermediaries enter and exit the market in peak and off-peak season, such that profits are kept in check. This seasonality does imply a small shift in market power in favour of farmers in off-peak season and in favour of intermediaries in the peak season.Research limitations/implicationsThe investigation concentrated on an important and relatively homogenous staple crop along its main trade route. More remote areas, where there is less of an abundance of matooke, might still be characterised by local monopsonies where intermediaries have more market power due to high search and transport costs. Similarly, (local) monopsonies might exist for products for which there is a smaller market (segment), for products with a stronger seasonal variation in supply and for more perishable products.Originality/valueWhile there is an important literature on the role of intermediaries in African agri-food value chains, the evidence on intermediary market power is scant. Beliefs on intermediary market power are largely based on anecdotal evidence from farmers or inferred from observed prices or market structures. The paper contributes in addressing this important knowledge gap by studying the matooke value chain in Uganda.
人们普遍认为,非洲农业食品价值链中的中间商拥有不成比例的市场力量。在本文中,作者通过揭示乌干达matooke(煮香蕉)价值链中农民、中间商和零售商的购买和销售价格、成本和利润率,并通过分析主流价值链和市场结构、季节性进入和退出动态以及链中的贸易关系来检验这一信念。设计/方法/方法本研究的数据是从乌干达西南部主要的matooke产区(Kabarole、Bunyangabo、Bushenyi、Isingiro和Mbarara)到首都坎帕拉周围主要城市市场的贸易路线上收集的。对383家生产商、172家收藏家和批发商以及71家零售商进行了结构化调查。此外,还举行了主要资料提供者访谈和焦点小组讨论。研究结果作者发现,中间商的价格加价(销售价格减去采购价格)因中间商的类型、季节和地点而异,但通常反映了将农产品从价值链下游转移到城市消费者手中的成本。作者没有找到证据表明在产业链中的中介机构中存在不成比例的市场力量。中介机构在旺季和淡季进入和退出市场,从而控制利润。这种季节性确实意味着市场力量在淡季有利于农民,而在旺季有利于中间商。研究局限/启示调查集中在其主要贸易路线上的一种重要且相对同质的主要作物上。更偏远的地区,没有那么多的马图克,可能仍然以当地垄断为特征,在那里,由于高昂的搜索和运输成本,中介机构拥有更大的市场力量。同样,(当地)垄断可能存在于市场(细分)较小的产品、供应季节性变化较大的产品和易腐产品。原创性/价值虽然有关于中介机构在非洲农业食品价值链中的作用的重要文献,但关于中介机构市场力量的证据很少。对中介市场力量的看法主要基于农民的轶事证据,或从观察到的价格或市场结构中推断出来。本文通过研究乌干达的马图克价值链,有助于解决这一重要的知识差距。

PurposeClimate change increases systematic risk for firms, especially those in the agricultural industry. Therefore, the need to examine the consequences of climate-related risks on agribusiness companies' financial performance across the globe and emerging markets has risen. In this context, the paper aims to investigate the effects of climate change risks on the financial performance of agriculture listed firms in Vietnam.Design/methodology/approachThe study sample includes 77 Vietnamese listed firms in the agricultural industry in the period of 2015–2019. The authors chose temperature, wind, rainfall and humidity proxies to measure climate change. The OLS regression, random regression and sub-sample analysis have been used to examine the impacts of climate risks on firms' financial performance.FindingsEmpirical results show that rain and temperature have positive impacts on financial performance of Vietnamese agriculture listed firms, while wind and humidity have insignificant impacts on financial performance.Research limitations/implicationsThe research helps researchers, businesses, practitioners and policymakers interested in the agricultural industry, especially those in developing and emerging countries, to develop a deep understanding of the impact of climate change risks on firm performance and therefrom prepare necessary measures to reduce the negative impacts.Originality/valueThis study adds to the literature stream on the impacts of climate change on financial performance. It is the first study to investigate this impact in Vietnam, a country which depends mainly on agriculture.

PurposeThis study analyzes the role of cooperative behavior in facing the risk of encouraging innovative agricultural production projects by small-scale farmers in the context of farmers in developing countries.Design/methodology/approachA within-subjects field experiment was conducted with small-scale Colombian panela cane farmers. The authors used the collected data to run the regression analyses.FindingsThe results suggest that when small farmers can follow cooperative behavior by joining a group and pooling resources to face risk, they are more willing to invest in a novel and profitable alternative, albeit riskier. However, the possibility of cooperating with a group to invest in a novel production project depends on its expected risk level.Research limitations/implicationsThese results will help develop agricultural policies for sustainable development. Establishing informal networks for small-scale farmers to deal with unpredictable risks may aid in developing innovative systems.Social implicationsAgriculture is highly vulnerable to climatic impacts, which, combined with the inherent risk of innovation, may reduce small farmers' willingness to adopt innovation. Cooperation appears to be a mechanism for pooling resources and facing risk.Originality/valueResearch has focused on experimentally testing the effect of cooperative behavior when facing risk. The authors contribute to the literature by demonstrating the impact of the ability of small-scale farmers in rural areas to collectively manage risk on investment in innovative projects.
目的本研究分析了发展中国家农民在面对鼓励小规模农民创新农业生产项目的风险时合作行为的作用。设计/方法/方法对哥伦比亚小规模种植甘蔗的农民进行了受试者内田间试验。作者使用收集的数据进行回归分析。研究结果表明,当小农户能够通过加入一个团体并集中资源来面对风险来遵循合作行为时,他们更愿意投资于一种新颖且有利可图的替代方案,尽管风险更大。然而,与一个集团合作投资一个新的生产项目的可能性取决于其预期的风险水平。研究局限性/影响这些结果将有助于制定可持续发展的农业政策。为小规模农民建立非正式网络以应对不可预测的风险可能有助于开发创新系统。社会影响农业极易受到气候影响,再加上创新的固有风险,可能会降低小农户采用创新的意愿。合作似乎是一种汇集资源和面对风险的机制。独创性/价值研究专注于通过实验测试面对风险时合作行为的效果。作者通过证明农村地区小规模农民集体管理风险的能力对创新项目投资的影响,为文献做出了贡献。

PurposeThis study aimed to understand the agri-entrepreneurial traits of undergraduate university students using machine learning (ML) algorithms.Design/methodology/approachThis study used a conceptual framework of individual-level determinants of entrepreneurship and ML. The Google Survey instrument was prepared on a 5-point scale and administered to 656 students in different sections of the same class during regular virtual classrooms in 2021. The datasets were analyzed and compared using ML.FindingsEntrepreneurial traits existed among students before attending undergraduate entrepreneurship courses. Establishing strong partnerships (0.359), learning (0.347) and people-organizing ability (0.341) were promising correlated entrepreneurial traits. Female students exhibited fewer entrepreneurial traits than male students. The random forest model exhibited 60% accuracy in trait prediction against gradient boosting (58.4%), linear regression (56.8%), ridge (56.7%) and lasso regression (56.0%). Thus, the ML model appeared to be unsuitable to predict entrepreneurial traits. Quality data are important for accurate trait predictions.Research limitations/implicationsFurther studies can validate K-nearest neighbors (KNN) and support vector machine (SVM) models against random forest to support the statement that the ML model cannot be used for entrepreneurial trait prediction.Originality/valueThis research is unique because ML models, such as random forest, gradient boosting and lasso regression, are used for entrepreneurial trait prediction by agricultural domain students.
目的利用机器学习(ML)算法了解大学生的农业创业特征。本研究使用了创业精神和ML的个人层面决定因素的概念框架。谷歌调查工具以5分制编制,并于2021年在常规虚拟教室中对同一班级不同部门的656名学生进行了管理。结果表明,大学生在参加本科创业课程前存在创业特质。建立牢固的伙伴关系(0.359)、学习能力(0.347)和组织能力(0.341)是有前景的相关创业特征。女生比男生表现出更少的创业特质。随机森林模型对梯度增强(58.4%)、线性回归(56.8%)、脊回归(56.7%)和套索回归(56.0%)的预测准确率为60%。因此,ML模型似乎不适合预测创业特征。高质量的数据对于准确的性状预测非常重要。进一步的研究可以验证k近邻(KNN)和支持向量机(SVM)模型对随机森林的影响,以支持机器学习模型不能用于创业特质预测的说法。原创性/价值本研究的独特之处在于ML模型,如随机森林、梯度提升和套索回归,被农业领域的学生用于创业特质预测。
