PurposeThis pragmatic investigation examines the dynamic nexus between crude oil prices and food inflation from South and Southeast Asian perspectives.Design/methodology/approachThis study investigates the asymmetric effects of global crude oil prices on food inflation using a nonlinear autoregressive distributed lag (ARDL) model with monthly data covering the period from May 2012 to April 2022.FindingsThe empirical evidence reveals that international crude oil has a substantial impact on food prices in the majority of countries. Additionally, the relevant outcome documents that the asymmetric effect of global crude oil on food inflation applies to Sri Lanka and Vietnam, while in the other countries, it is symmetric.Research limitations/implicationsConsidering the optimistic outcomes, this empirical investigation is certain to have important shortcomings. Initially, the conclusions drawn from the above findings were based only on detailed assessments of the aforementioned variables' data over a 10-year period. The current scholarly analysis investigates the existence of an asymmetric impact of crude oil on food inflation, limited to six Asian countries. On the other hand, considering a greater number of Asian economies could enhance the analysis’s robustness and precision.Originality/valueThe current research aims to contribute to the existing literature on food inflation and global oil prices in the following ways: First, this study investigates the nexus between global crude oil and food inflation in a novel way, considering the nonlinear relationship between the variables. To figure out the nonlinear relationship or uneven effect of the global oil shock on food prices, we use the nonlinear ARDL model. Secondly, as food inflation is one of the major issues for the South and Southeast Asian economies, this empirical investigation broadens the analysis by incorporating a perspective from South and Southeast Asia, an area largely overlooked by previous researchers. Finally, we are very optimistic about the phenomenal contribution of current analysis to comprehending the conception of oil and food price dynamics from a broader perspective to achieve the Sustainable Development Goal (SDG), which aims for a sustainable resolution to end hunger in all its forms by 2030 and to accomplish food security, especially in emerging economies.
本研究采用非线性自回归分布滞后模型(ARDL),利用 2012 年 5 月至 2022 年 4 月期间的月度数据,研究了全球原油价格对食品通胀的非对称影响。此外,相关结果表明,全球原油对粮食通胀的非对称影响适用于斯里兰卡和越南,而在其他国家则是对称的。最初,从上述研究结果中得出的结论仅基于对上述变量 10 年间数据的详细评估。目前的学术分析调查了原油对食品通胀的非对称影响,仅限于六个亚洲国家。另一方面,考虑更多的亚洲经济体可以提高分析的稳健性和精确性。 原创性/价值 本研究旨在从以下几个方面为现有的有关粮食通胀和全球油价的文献做出贡献:首先,本研究以一种新颖的方式研究了全球原油和粮食通胀之间的关系,考虑了变量之间的非线性关系。为了弄清全球石油冲击对食品价格的非线性关系或不均衡影响,我们使用了非线性 ARDL 模型。其次,由于粮食通胀是南亚和东南亚经济体的主要问题之一,这项实证调查通过纳入南亚和东南亚的视角拓宽了分析范围,而这一领域在很大程度上被以往的研究者所忽视。最后,我们非常看好当前分析对从更广阔的视角理解石油和粮食价格动态概念的巨大贡献,以实现可持续发展目标(SDG),该目标旨在可持续地解决到 2030 年消除一切形式饥饿的问题,并实现粮食安全,尤其是在新兴经济体。

PurposeWith increasing wine consumption in Armenia, both residents and inbound tourists have become attractive target groups for wine sales, which are stimulated by wine tourism activities. The objective of this explorative study is to shed light on the potential of wine tourism for rural development in Armenia.Design/methodology/approachThe paper starts with a structured and interdisciplinary literature review. Based on qualitative surveys among local tour operators and wine producers, and complemented by three expert interviews, the offer of wine tourism activities in Armenia will then be analyzed.FindingsEach of the surveyed wine producers offers wine tourism activities. Foreign tourists know little about the Armenian wine industry, however, and are interested in cultural experiences and Armenia’s breathtaking nature. Armenian wine producers need to understand the expectations of their target groups to develop or adapt their offers successfully.Research limitations/implicationsDue to the explorative nature of this study, the sample size of the surveyed wineries and tour operators is small and hence not representative. In addition, only local tour operators were surveyed. The sample should be extended to include foreign tour operators and more wineries in future research projects.Originality/valueWhereas first studies on the structure and competitiveness of the Armenian wine sector exist, there is no survey on the general wine tourism in Armenia and its potential to foster rural development.
目的随着亚美尼亚葡萄酒消费量的增长,居民和入境游客已成为葡萄酒销售的吸引目标群体,而葡萄酒旅游活动则刺激了这一目标群体的增长。本探索性研究旨在揭示葡萄酒旅游对亚美尼亚农村发展的潜力。在对当地旅行社和葡萄酒生产商进行定性调查的基础上,辅以三次专家访谈,对亚美尼亚葡萄酒旅游活动的提供情况进行分析。然而,外国游客对亚美尼亚葡萄酒业知之甚少,他们感兴趣的是文化体验和亚美尼亚令人惊叹的自然风光。亚美尼亚葡萄酒生产商需要了解其目标群体的期望,以便成功开发或调整其产品。研究局限性/影响由于本研究具有探索性,受访酒庄和旅游经营者的样本量较小,因此不具有代表性。此外,只调查了本地旅游经营者。原创性/价值虽然已有关于亚美尼亚葡萄酒行业结构和竞争力的初步研究,但还没有关于亚美尼亚葡萄酒旅游业及其促进农村发展潜力的调查。

PurposeWe study five exogenous shocks: climate, violence, price hikes, spoilage and the COVID-19 lockdown. We analyze the association between these shocks and trader characteristics, reflecting trader vulnerability.Design/methodology/approachUsing primary survey data on 1,100 Nigerian maize traders for 2021 (controlling for shocks in 2017), we use probit models to estimate the probabilities of experiencing climate, violence, disease and cost shocks associated with trader characteristics (gender, size and region) and to estimate the probability of vulnerability (experiencing severe impacts).FindingsTraders are prone to experiencing more than one shock, which increases the intensity of the shocks. Price shocks are often accompanied by violence, climate and COVID-19 shocks. The poorer northern region is disproportionately affected by shocks. Northern traders experience more price shocks while Southern traders are more affected by violence shocks given their dependence on long supply chains from the north for their maize. Female traders are more likely to experience violent events than men who tend to be more exposed to climate shocks.Research limitations/implicationsThe data only permit analysis of the general degree of impact of a shock rather than quantifying lost income.Originality/valueThis paper is the first to analyze the incidence of multiple shocks on grain traders and the unequal distribution of negative impacts. It is the first such in Africa based on a large sample of grain traders from a primary survey.
目的我们研究了五种外来冲击:气候、暴力、价格上涨、变质和 COVID-19 封锁。我们分析了这些冲击与贸易商特征之间的关联,反映了贸易商的脆弱性。设计/方法/途径利用 2021 年 1100 名尼日利亚玉米贸易商的原始调查数据(控制了 2017 年的冲击),我们使用概率模型估算了与贸易商特征(性别、规模和地区)相关的经历气候、暴力、疾病和成本冲击的概率,并估算了脆弱性(经历严重冲击)的概率。研究结果贸易商容易经历不止一次冲击,这增加了冲击的强度。价格冲击往往伴随着暴力、气候和 COVID-19 冲击。北部贫困地区受冲击的影响尤为严重。北部贸易商受到的价格冲击更大,而南部贸易商则更多地受到暴力冲击的影响,因为他们的玉米依赖于来自北部的漫长供应链。女性贸易商比男性贸易商更容易受到暴力事件的影响,而男性贸易商往往更容易受到气候冲击的影响。研究局限性/意义本文首次分析了多种冲击对粮食贸易商的影响以及负面影响的不平等分布。这也是非洲第一份基于初级调查的大样本谷物贸易商的报告。

PurposeThis study explores the integration of smallholder farmers into the export market in Vietnam, an emerging economy. By introducing a prospective framework, we seek to provide insight into factors that influence this integration process.Design/methodology/approachThis study examines the expected growth and entry of Vietnamese smallholder farmers into high-value export markets. We collected information from 200 independent farmers as well as from five local extension workers, who provided information on 50 farmers.FindingsThe study reveals that the adoption of new business models is more influential than the variables traditionally included in models of export-market integration in predicting expected growth and entry into high-value export markets. In addition, the results highlight divergent views between farmers and extension workers regarding the role of collectors, with farmers perceiving collectors as potential partners, while extension workers see them as impediments to growth.Research limitations/implicationsThe prospective model presented in this study highlights the importance of policy interventions aimed at promoting new business models and addressing infrastructure and capital constraints for the sustainable transformation of agricultural sectors in emerging markets.Originality/valueThis is one of the first articles to apply a prospective approach to export-market integration and demonstrate its efficacy through an empirical study. The suggested prospective approach could facilitate the design of policies aimed at export-market integration within the context of dynamic, emerging markets.
目的本研究探讨了新兴经济体越南小农融入出口市场的情况。通过引入一个前瞻性框架,我们试图深入了解影响这一整合过程的因素。本研究探讨了越南小农的预期增长和进入高价值出口市场的情况。我们收集了 200 名独立农民以及 5 名当地推广人员的信息,他们提供了 50 名农民的信息。研究结果研究表明,在预测预期增长和进入高价值出口市场方面,采用新的商业模式比传统出口市场一体化模型中的变量更具影响力。此外,研究结果还突显了农民和推广人员对收货人作用的不同看法,农民认为收货人是潜在的合作伙伴,而推广人员则认为收货人是增长的障碍。研究局限性/意义本研究提出的前瞻性模型突显了政策干预的重要性,这些政策干预旨在促进新的商业模式,解决基础设施和资本制约因素,从而实现新兴市场农业部门的可持续转型。所建议的前瞻性方法有助于在充满活力的新兴市场背景下制定出口市场一体化政策。

PurposeThe purpose of this paper is to critically examine the multinational oil companies’ (MOCs) corporate social responsibility (CSR) initiatives in Nigeria. Its special focus is to investigate the impact of the global memorandum of understanding (GMoU) on mainstreaming gender sensitivity in cash crop market supply chains in the Niger Delta region of Nigeria.Design/methodology/approachThis paper adopts an explanatory research design with a mixed method to answer the research questions and test the hypotheses. A total of 1,200 rural women respondents were sampled across the Niger Delta region.FindingsResults from the use of a combined logit model and propensity score matching indicate a significant relationship between the GMoU model and mainstreaming gender sensitivity in cash crop market supply chains in the Niger Delta.Research limitations/implicationsThis study implies that MOCs’ CSR interventions that improve women’s access to land and encourage better integration of food markets through improved roads and increased mobile networks would enable women to engage in cash crop production.Social implicationsThis implies that improving access to credit through GMoU cluster farming targeted at female farmers would improve access to finance and extension services for women in cash crop production in the Niger Delta.Originality/valueThis research contributes to the gender debate in the agricultural value chain from a CSR perspective in developing countries and is rational for demands for social projects by host communities. It concludes that businesses have an obligation to help solve problems of public concern.
本文旨在批判性地研究跨国石油公司(MOCs)在尼日利亚的企业社会责任(CSR)举措。本文特别关注全球谅解备忘录(GMoU)对尼日利亚尼日尔三角洲地区经济作物市场供应链中性别敏感性主流化的影响。在尼日尔三角洲地区共抽取了 1,200 名农村妇女作为受访者。研究结果采用组合 logit 模型和倾向得分匹配法得出的结果表明,GMoU 模型与尼日尔三角洲经济作物市场供应链中性别敏感性主流化之间存在显著关系。研究局限性/影响本研究表明,通过改善道路和增加移动网络,改善妇女获得土地的机会并鼓励更好地整合粮食市场,从而使妇女能够从事经济作物生产的移动运营公司企业社会责任干预措施。社会影响这意味着,通过以女性农民为目标的 GMoU 集群农业来改善获得信贷的机会,将改善尼日尔三角洲地区从事经济作物生产的妇女获得融资和推广服务的机会。研究认为,企业有义务帮助解决公众关心的问题。

PurposeThis study analyzes the impact of COVID-19 on agricultural production in South India by evaluating the influence of market channels and socioeconomic conditions on the production decisions of farmers during two key cropping seasons. We base our analysis on primary data from 200 marginal, small and medium farmers, primarily focusing on the key seasonal crops, namely paddy and black gram.Design/methodology/approachWe studied the downstream supply chains of paddy and black gram crops in the district of Villupuram, situated in the South Indian state of Tamil Nadu. Using a Bi-Probit model, we analyzed the production decisions of marginal, small and medium farmers engaged in paddy and black gram cultivation. Various factors are considered, including farmers’ socioeconomic characteristics, gender, market channels accessed and the coping strategies employed.FindingsAfter the easing of lockdown measures in June 2020, our research revealed substantial disruptions in agricultural production during the critical Kharif and Rabi seasons. Most farmers refrained from returning to their fields during the Kharif season; those who did produced millet as the main crop. Factors such as choice of market channels in previous seasons, economic status, access to all-weather roads, labor availability, gender and coping strategies played an important role in the return to production in the subsequent Kharif and Rabi seasons.Research limitations/implicationsOur data revealed several interesting threads related to price volatility, irrigation and access to markets and their impact on food security. The role of intermediaries and market channels in providing liquidity emerges as an important aspect of farmers' choice of markets. The pandemic impacted all these factors, but a detailed analysis was beyond the scope of this study.Social implicationsWe also find that resilience to economic shocks varies not only by economic status but also by gender and social groups. Farmers with female members are more likely to be resilient, and marginal and small farmers primarily belong to social groups that are economically less developed.Originality/valueThis study contributes to the literature on factors influencing farmer choice and decision-making and provides nuances to discussions by analyzing crop-specific supply chains, highlighting the critical role of socioeconomic factors. It also highlights the role of demographics and infrastructural factors like access to all-weather roads and access to markets that influence farmers’ production decisions.
目的本研究通过评估市场渠道和社会经济条件对农民在两个关键种植季节的生产决策的影响,分析 COVID-19 对南印度农业生产的影响。我们的分析基于 200 名边缘、小型和中型农户的原始数据,主要侧重于主要季节性作物,即水稻和黑禾。我们使用 Bi-Probit 模型分析了从事水稻和黑糯米种植的边缘、小型和中型农户的生产决策。研究考虑了各种因素,包括农民的社会经济特征、性别、进入市场的渠道以及所采用的应对策略。研究结果在 2020 年 6 月放松封锁措施后,我们的研究显示,在关键的 Kharif 和 Rabi 季节,农业生产受到了严重干扰。在 Kharif 季节,大多数农民没有返回田地;返回田地的农民主要种植小米。前几季市场渠道的选择、经济状况、全天候道路的使用、劳动力的可用性、性别和应对策略等因素在随后的 Kharif 和 Rabi 季节恢复生产中发挥了重要作用。中间商和市场渠道在提供流动性方面的作用是农民选择市场的一个重要方面。大流行病对所有这些因素都产生了影响,但详细分析超出了本研究的范围。社会影响我们还发现,抵御经济冲击的能力不仅因经济状况而异,而且因性别和社会群体而异。有女性成员的农户更有可能具有抵御能力,而边缘农户和小农户主要属于经济欠发达的社会群体。原创性/价值本研究为有关影响农户选择和决策的因素的文献做出了贡献,并通过分析特定作物供应链为讨论提供了细微差别,突出了社会经济因素的关键作用。本研究还强调了影响农民生产决策的人口统计和基础设施因素的作用,如全天候道路和市场准入。

PurposeCollaboration in agricultural value chains (AVCs) has the potential to increase smallholders’ participation in international value chains and increase their benefits from participation. This scoping review explores existing collaboration models among stakeholders of AVCs in developing countries, examines enablers and constraints of collaboration and identifies policy gaps.Design/methodology/approachWe systematically searched three databases, CAB Abstracts, Econlit (EBSCO) and Agricola, for studies published between 2005 and 2023 and included 59 relevant studies on AVC collaboration.FindingsThe primary motivations for collaboration are to enhance market access and improve product quality. Key outcomes of collaboration include improvements in farmers’ welfare, market participation and increased production; only a few studies consider improved risk management as an important outcome. Robust support from government and non-governmental entities is a primary enabler of collaboration. Conversely, conflicts of interest among stakeholders and resource limitations constrain collaboration possibilities. Collaboration involving high-value crops prioritizes income increases, whereas collaboration involving staple crops focuses on improving household food security.Research limitations/implicationsThis study may have publication bias as unsuccessful instances of collaboration are less likely to be published.Originality/valueThis study is unique in highlighting collaboration models’ characteristics and identifying AVC policy and programmatic areas where private firms, farmers’ groups, local governments and donor agencies can contribute.
目的 农业价值链(AVCs)中的合作有可能提高小农对国际价值链的参与度,并增加他们从参与中获得的收益。我们系统地检索了 CAB Abstracts、Econlit (EBSCO) 和 Agricola 三个数据库中 2005 年至 2023 年间发表的研究报告,共收录了 59 项关于农业价值链合作的相关研究。研究结果合作的主要动机是加强市场准入和提高产品质量。合作的主要成果包括改善农民福利、提高市场参与度和增加产量;只有少数研究认为改善风险管理是一项重要成果。政府和非政府实体的大力支持是促进合作的主要因素。相反,利益相关者之间的利益冲突和资源限制制约了合作的可能性。涉及高价值作物的合作优先考虑增加收入,而涉及主食作物的合作则侧重于改善家庭粮食安全。研究局限性/影响本研究可能存在发表偏差,因为不成功的合作案例较少发表。

PurposeThe purpose of the study is to estimate the willingness to pay (WTP) for major chemical fertilizers and revisit the fertilizer subsidy policy in Nepal.Design/methodology/approachWe surveyed 619 households from six districts and assessed farmers’ WTP for urea, diammonium phosphate (DAP) and muriate of potash (MOP) during the fertilizer crisis. Our study elicited the WTP for fertilizers when fertilizers were not available on the market. A modified payment card approach was used to elicit farmers’ WTP.FindingsThe study found that farmers who buy fertilizer from agrodealers, buy from gray markets, have bank accounts, are willing to take a risk, have strong or medium economic conditions and incur higher travel costs have a higher WTP for fertilizers. Farmers in sampled areas, on average, are willing to pay 31 percent more for urea, 13 percent more for DAP and 19 percent more for MOP than the government recommended fertilizer price.Research limitations/implicationsThe design of the payment card and the estimation techniques used to fit the valuation function are likely to influence WTP.Originality/valueOverall, literature on households’ WTP for fertilizers in developing countries is scarce. Our study contributes to the knowledge of WTP for fertilizers.
本研究旨在估算尼泊尔主要化肥的支付意愿(WTP),并重新审视化肥补贴政策。我们调查了六个县的 619 个家庭,评估了化肥危机期间农民对尿素、磷酸二铵(DAP)和钾肥的支付意愿。我们的研究调查了在市场上买不到化肥时农民对化肥的购买意愿。研究发现,从农资经销商处购买化肥、从灰色市场购买化肥、拥有银行账户、愿意承担风险、经济条件较好或中等、旅行成本较高的农民对化肥的购买意愿较高。抽样地区的农民平均愿意为尿素多支付 31%的价格,为磷酸二铵多支付 13%的价格,为澳门葡京娱乐平台多支付 19%的价格。研究局限性/意义支付卡的设计和用于拟合估值函数的估算技术可能会影响 WTP。我们的研究有助于加深人们对肥料购买意愿的了解。

PurposeThis study assesses the extent to which integrated extension services contribute to the adoption of climate-smart agriculture (CSA) innovations within the cotton value chain in Burkina Faso.Design/methodology/approachTo address the research question, a probit multivariate econometric model with sample selection is utilized. The model is applied to a random sample of farmers (n = 510), and the endogeneity is addressed through a control function approach.FindingsThe study highlights the central role of value chains, particularly in the cotton sector, in overcoming resource scarcity through integrated extension services. Findings show that smallholder farmers who benefit from sound extension services are more willing to adopt and diversify CSA technologies. These include improved seeds, conservation techniques, adapted planting dates and mechanization. This study confirms the synergistic nature of these technologies and emphasizes that effective climate risk mitigation depends on the combined adoption of CSA technologies.Research limitations/implicationsThe use of cross-sectional data limits the analysis of long-term farmer behavior, and due to data limitations, the focus was primarily on the contributions of cotton companies and farmers to climate risk mitigation. Future research using panel data across the value chain could provide a more robust insights for policy decision-making.Originality/valueThe study contributes to the existing body of knowledge by emphasizing the crucial role of integrated extension services within the cotton value chain in developing countries. This highlights the critical benefits for farmers and emphasizes the need to diversify modern technologies to effectively combat climate change and its variability in agriculture.
目的 本研究评估了综合推广服务在多大程度上促进了布基纳法索棉花价值链中气候智能型农业(CSA)创新的采用。该模型适用于随机抽样的农民(n = 510),并通过控制函数方法解决了内生性问题。研究结果该研究强调了价值链在通过综合推广服务克服资源稀缺方面的核心作用,尤其是在棉花行业。研究结果表明,受益于良好推广服务的小农更愿意采用 CSA 技术并使其多样化。这些技术包括改良种子、保护技术、调整种植日期和机械化。这项研究证实了这些技术的协同作用,并强调有效的气候风险缓解取决于综合采用 CSA 技术。研究局限性/意义横截面数据的使用限制了对农民长期行为的分析,而且由于数据的局限性,研究重点主要放在棉花公司和农民对气候风险缓解的贡献上。该研究强调了综合推广服务在发展中国家棉花价值链中的关键作用,为现有知识体系做出了贡献。这突出了农民的重要利益,强调了现代技术多样化的必要性,以有效应对气候变化及其在农业中的多变性。
