Abstract Rwanda’s “Crop Intensification Program (CIP)” is primarily a land consolidation program aimed at improving agricultural productivity and food security. The program, which began in 2007, focuses on monocropping and commercialization of six priority crops: maize, wheat, rice, white potato, beans, and cassava. CIP has facilitated easy access to improved seed stocks, fertilizer, extension services, and postharvest handling and storage services. Although studies have documented the impact of CIP on changes in farm yield, incomes, and productivity, less is known about its impact on food prices. In this study, we examine the crop-food price differences in intensive monocropped CIP and non-intensive monocropped CIP zones in Rwanda. Specifically, the study evaluates price variations of beans and maize along with complementary food crops in intensive and non-intensive monocropped zones before and after the introduction of the CIP policy. We find that the CIP policy is not associated with differences in CIP crop prices between the intensive and non-intensive monocropped zones. Over time, prices increased for CIP crops but generally, the crop prices in the two zones were cointegrated. Prices for non-CIP crops in the two different zones did show price differentials prior to the implementation of CIP, with the prices in intensive monocropped zones being greater than in the non-intensive monocropped zones. Moreover, the prices in intensive areas are cointegrated with prices in non-intensive areas for maize and beans and these prices are converging. This indicates that farmers who intensively produced one CIP crop were able to go to the market and purchase other food crops and that price differences between zones have decreased over time, potentially making the CIP intensive farmers better off.
卢旺达的“作物集约化计划(CIP)”主要是一项旨在提高农业生产力和粮食安全的土地整理计划。该项目始于2007年,重点关注玉米、小麦、水稻、白马铃薯、豆类和木薯等六种重点作物的单作和商业化。CIP使人们更容易获得改良的种子库存、肥料、推广服务以及采后处理和储存服务。虽然研究已经记录了CIP对农业产量、收入和生产力变化的影响,但对其对食品价格的影响知之甚少。在本研究中,我们研究了卢旺达集约化单作CIP区和非集约化单作CIP区作物-粮食价格差异。具体而言,该研究评估了在实施CIP政策前后集约化和非集约化单作区豆类和玉米以及辅助性粮食作物的价格变化。我们发现CIP政策与集约化和非集约化单作区之间CIP作物价格的差异无关。随着时间的推移,CIP作物的价格上涨,但总的来说,两个区域的作物价格是协整的。在实施CIP之前,两个不同区域的非CIP作物价格确实存在价格差异,集约化单作区的价格高于非集约化单作区的价格。此外,集约地区的玉米和豆类价格与非集约地区的价格是协整的,而且这些价格正在趋同。这表明集约化生产一种CIP作物的农民能够去市场购买其他粮食作物,区域之间的价格差异随着时间的推移而减少,可能使集约化CIP的农民变得更好。

Abstract Rwanda has experienced exceptional economic growth since 2000 despite more than 60% of the predominately-agrarian population living on less than $1.25 a day. Approximately 76% of the country’s working population are engaged in agricultural production, which makes up about one-third of the national economy. Agriculture is also an important source of foreign exchange, making up about 63% of the value of Rwanda’s exports. An important component of household diets – food produced on subsistence agriculture parcels averaging 0.6 ha – faces the challenge by government and private sector development to replace subsistence farming with a value-creating market-oriented food sector. A complex set of relationships across public incentives and programs encourages participation in markets. Designed to promote wealth, the Crop Intensification Program (CIP) has increased access to land, inputs, extension services, markets, supply chains, etc. Wealth and access to land are the dominant predictors of the ability to participate in markets and the extent of participation. For example, smallholders producing a diversity of crops are more likely to sell in markets. Within the confluence of competing policy objectives and market forces, further research is necessary to understand the household-level tradeoffs of both producers and consumers along the food value chain.
自2000年以来,卢旺达经历了非凡的经济增长,尽管超过60%的以农业为主的人口每天的生活费不到1.25美元。全国约76%的劳动人口从事农业生产,约占国民经济的三分之一。农业也是一个重要的外汇来源,约占卢旺达出口价值的63%。家庭饮食的一个重要组成部分——平均0.6公顷的自给农业生产的粮食——面临着政府和私营部门发展的挑战,即以创造价值的市场导向的粮食部门取代自给农业。公共激励和项目之间的一系列复杂关系鼓励人们参与市场。旨在促进财富的作物集约化计划(CIP)增加了获得土地、投入、推广服务、市场、供应链等的机会。财富和获得土地是参与市场能力和参与程度的主要预测因素。例如,生产多种作物的小农更有可能在市场上销售。在相互竞争的政策目标和市场力量的汇合中,有必要进行进一步的研究,以了解食品价值链上生产者和消费者在家庭一级的权衡。

Abstract The global policy community has largely converged on climate-smart agriculture as a solution to various problems driven by climate change, but mass adoption of the crucial innovations presents challenges – particularly in the developing world. Widespread, meaningful, and rapid adoption of climate-smart agriculture will require an appropriate enabling environment. This study uses the political will and public will approach to identify the obstacles and opportunities for upscaling of climate-smart agriculture innovations. In 2015 and 2018, two rounds of semi-structured stakeholder and expert interviews conducted by researchers in Uganda identified four relevant obstacle categories: agricultural extension; communication infrastructure; basic and agricultural infrastructure; and other incentives and disincentives. These categories are related to the five definitional components of public will to reveal pathways for enabling social change. Importantly, both infrastructure and appropriate incentives are necessary for diffusion and then continued use of climate-smart agriculture innovations, often in interrelated ways. The study concludes with a detailed discussion of the implications for industry, government, and donors.
摘要全球政策界在很大程度上已经将气候智能农业作为气候变化引发的各种问题的解决方案,但关键创新的大规模采用带来了挑战,尤其是在发展中国家。广泛、有意义和快速采用气候智能农业将需要一个适当的有利环境。这项研究使用政治意愿和公众意愿的方法来确定气候智能农业创新升级的障碍和机会。2015年和2018年,乌干达研究人员进行了两轮半结构化的利益相关者和专家访谈,确定了四类相关障碍:农业推广;通信基础设施;基础设施和农业基础设施;以及其他激励和抑制措施。这些类别与揭示实现社会变革途径的公共意愿的五个定义组成部分有关。重要的是,基础设施和适当的激励措施对于推广和继续使用气候智能型农业创新是必要的,通常是以相互关联的方式。该研究最后详细讨论了对行业、政府和捐助者的影响。

Distributional Weights in Benefit-Cost Analysis: Examples from Rwanda and Uganda 效益成本分析中的分配权重:以卢旺达和乌干达为例

Abstract The question of how to allocate scarce agricultural research and development dollars is significant for developing countries. Historically, benefit/cost analysis has been the standard for comparing the relative benefits of alternative investments. We examine the potential of shifting the implicit equal weights approach to benefit/cost analysis, as well as how a systematic variation in welfare weights may affect different groups important to policy makers. For example, in the case of Rwandan coffee, a shift in the welfare weights that would favor small coffee producers in Rwanda over foreign consumers of Rwandan coffee would increase the support for investments in small producer coffee projects. Generally, changes in welfare weights alter the ordering for selecting investments across alternative projects.
摘要如何分配稀缺的农业研发资金对发展中国家来说意义重大。从历史上看,效益/成本分析一直是比较替代投资相对效益的标准。我们研究了将隐性等权重方法转变为收益/成本分析的潜力,以及福利权重的系统变化如何影响对决策者重要的不同群体。例如,就卢旺达咖啡而言,福利权重的转变将有利于卢旺达的小型咖啡生产商,而不是卢旺达咖啡的外国消费者,这将增加对小型生产商咖啡项目投资的支持。一般来说,福利权重的变化会改变选择替代项目投资的顺序。

Abstract Private agricultural research and development can foster the growth of agricultural productivity in the diverse farming systems of the developing world comparable to the public sector. We examine the extent to which technologies developed by private entities reach smallholder and resource-poor farmers, and the impact they have on poverty reduction. We critically review cases of successfully deployed improved agricultural technologies delivered by the private sector in both large and small developing countries for instructive lessons for policy makers around the world.
与公共部门相比,私营农业研究和发展可以促进发展中国家多样化农业系统中农业生产力的增长。我们研究了私营实体开发的技术在多大程度上惠及小农户和资源匮乏的农民,以及它们对减贫的影响。我们认真审查了私营部门在大发展中国家和小发展中国家成功部署改进农业技术的案例,为世界各地的决策者提供了有益的教训。

Abstract The carbon and land footprint of 26 certified food products – geographical indications and organic products and their conventional references are assessed. This assessment goes beyond existing literature by (1) designing a calculation method fit for the comparison between certified food and conventional production, (2) using the same calculation method and parameters for 52 products – 26 Food Quality Schemes and their reference products – to allow for a meaningful comparison, (3) transparently documenting this calculation method and opening access to the detailed results and the underlying data, and (4) providing the first assessment of the carbon and land footprint of geographical indications. The method used is Life Cycle Assessment, largely relying on the Cool Farm Tool for the impact assessment. The most common indicator of climate impact, the carbon footprint expressed per ton of product, is not significantly different between certified foods and their reference products. The only exception to this pattern are vegetal organic products, whose carbon footprint is 16% lower. This is because the decrease in greenhouse gas emissions from the absence of mineral fertilizers is never fully offset by the associated lower yield. The climate impact of certified food per hectare is however 26% than their reference and their land footprint is logically 24% higher. Technical specifications directly or indirectly inducing a lower use of mineral fertilizers are a key driver of this pattern. So is yield, which depends both on terroir and farming practices. Overall, this assessment reinforces the quality policy of the European Union: promoting certified food is not inconsistent with mitigating climate change.
摘要对26种经认证的食品——地理标志和有机产品及其常规参考——的碳足迹和土地足迹进行了评估。该评估超越了现有文献,(1)设计了一种适用于认证食品和传统生产之间比较的计算方法,(2)对52种产品——26种食品质量计划及其参考产品——使用相同的计算方法和参数,以进行有意义的比较,(3)透明地记录这种计算方法,并开放对详细结果和基础数据的访问,以及(4)提供对地理标志的碳足迹和土地足迹的首次评估。使用的方法是生命周期评估,主要依靠Cool Farm Tool进行影响评估。气候影响最常见的指标,即每吨产品的碳足迹,在认证食品及其参考产品之间没有显著差异。这种模式的唯一例外是植物有机产品,其碳足迹低16%。这是因为缺乏矿物肥料造成的温室气体排放量的减少从未被相关的较低产量完全抵消。然而,每公顷认证食品对气候的影响比其参考值高26%,其土地足迹从逻辑上讲高出24%。直接或间接减少矿物肥料使用的技术规范是这种模式的关键驱动因素。产量也是如此,这取决于风土和农业实践。总的来说,这一评估强化了欧盟的质量政策:推广认证食品与缓解气候变化并不矛盾。

Abstract The purpose of this paper is to assess the effect of experienced quality attributes, credence quality attributes and demographic factors affecting green-skin avocado consumption. Data for the present study came from a consumer online survey to 355 avocado consumers. Consumer preferences were modeled by an ordered logit model. Results indicate that experienced quality attributes are the main drivers for green-skin avocado followed by origin and health credence attributes, respectively. Demographic factors other than ethnicity do not play a significant role for green-skin avocado consumption. Among other things, the findings indicate that consumers place a higher valuation on higher fat content compared to low calorie content, implying that the latter attribute should not be touted at the expense of the former. To the extent possible, the industry should focus on cultivars with higher fat content and develop promotional activities to target non-Hispanic consumers. The present study constitutes an effort to contribute to the existing literature as it explores the role of health credence attributes, a topic that has not received much attention.
摘要本文的目的是评估体验质量属性、信任质量属性和人口统计学因素对绿皮鳄梨消费的影响。本研究的数据来自对355名鳄梨消费者的在线调查。消费者偏好采用有序logit模型进行建模。结果表明,体验质量属性是绿皮鳄梨的主要驱动因素,其次分别是原产地和健康信用属性。种族以外的人口因素对绿皮鳄梨的消费没有显著影响。除其他外,研究结果表明,与低热量含量相比,消费者对高脂肪含量的评价更高,这意味着不应以牺牲前者为代价来吹捧后者。该行业应尽可能关注脂肪含量较高的品种,并针对非西班牙裔消费者开展促销活动。本研究旨在为现有文献做出贡献,因为它探讨了健康信任属性的作用,而这一主题并未受到太多关注。

Abstract The research aims of this study are bi-fold: to study factors influencing the uptake of contract farming (CF) and to compare the predicting power of the artificial neural network model (ANN) and the Multinomial Logit Model (MNL) on predicting CF participation in the Mekong Delta, Vietnam. ANN and MNL were employed to analyze on the basis of the transaction cost theory. To validate the ANN, a 10-fold cross-validation procedure was applied to avoid model overfitting. The sensitivity analysis of ANN was used to elicit the magnitude of the correlation between predictors. Multicollinearity was examined with all VIFs lower than two. Among predictors, the most influential roles of the cooperatives and the extension agents/services in supporting CF participation are reported. Also, farmers who conduct frequent access to the market incline to participate in CF. Risk perceptions and preferences are dissimilar across domains, which are also mainly interpreted that risk-averse farmers tend to opt for CF as an effective solution to risks perceived. Thus, heterogeneous approaches should be tailored to promote CF. The findings suggest that MNL outperforms ANN in terms of accuracy percentage and mean absolute error (MAE). However, this result should not be generalized base on the constraint of the data threshold as articulated in the study. The sensitivity analysis of ANN and the estimation results of the MNL relatively agreed on the importance of model predictors. This study is the first to investigate the impacts of the domain-specific risk perceptions and attitudes on CF and also contribute to the debate over the performance between the conventional econometric models versus machine learning techniques.
摘要本研究的研究目的是双重的:研究影响越南湄公河三角洲地区承包农业(CF)吸收的因素,并比较人工神经网络模型(ANN)和多项Logit模型(MNL)对越南湄公河三角洲地区承包农业参与的预测能力。在交易成本理论的基础上,采用人工神经网络和MNL进行分析。为了验证人工神经网络,采用了10倍交叉验证程序来避免模型过拟合。使用人工神经网络的敏感性分析来得出预测因子之间的相关性程度。所有vif均小于2时,检验多重共线性。报告指出,在预测因素中,合作社和推广机构/服务机构在支持CF参与方面发挥了最具影响力的作用。此外,频繁进入市场的农民倾向于参与CF。不同领域的风险感知和偏好不同,这也主要解释为风险厌恶的农民倾向于选择CF作为感知风险的有效解决方案。因此,应该定制异构方法来促进CF。研究结果表明,MNL在准确率和平均绝对误差(MAE)方面优于ANN。然而,这一结果不应该基于研究中所阐述的数据阈值的约束而一般化。人工神经网络的敏感性分析与MNL的估计结果在模型预测因子的重要性上比较一致。这项研究首次调查了特定领域的风险感知和态度对CF的影响,也有助于传统计量经济模型与机器学习技术之间的性能争论。

Abstract Food quality schemes (FQS: organic and geographical indication products) are often supposed to be more sustainable by their political advocates. We explore the social sustainability advantage of FQS through the lens of supply chains’ bargaining power (BP) distribution. We propose an indicator synthesizing different sources underlying BP (competition-based, transactional, institutional) and counting two dimensions (fair BP distribution and adaptation capacity), that we apply to 18 FQS supply chains and corresponding reference. FQS perform better than their reference products on both dimensions. This better performance is due to a combination of sources.
摘要食品质量计划(FQS:有机和地理标志产品)通常被其政治倡导者认为更具可持续性。我们从供应链议价能力(BP)分布的角度探讨了FQS的社会可持续性优势。我们提出了一个指标,综合了BP的不同来源(基于竞争的、交易的、机构的),并计算了两个维度(公平的BP分配和适应能力),我们将其应用于18个FQS供应链并提供相应的参考。FQS在两个维度上都优于其参考产品。这种更好的性能是由于多种来源的结合。

Abstract This article addresses the issue of the profitability of Food Quality Scheme (FQS) products as compared to reference products, which are defined as analogous products without quality label. We approach this question by taking into account the level of the value chain (upstream, processing, and downstream), the sector (vegetal, animal, seafood) and the type of FQS (PGI, PDO, Organic). We collected original data for several products produced in selected European countries, as well as in Thailand and Vietnam. Comparisons depending on value chain level, sector and FQS are possible by using two comparable indicators: price premium and net price premium (including cost differential). The following principal conclusions were reached: 1) Price is higher for FQS products than for the reference products, regardless of the production level, the type of FQS or the sector; 2) Price premiums generated by FQS do not differ along the value chain, nor between sectors (vegetal, animal or seafood/fish); 3) Price premium for organic products is significantly higher than for PGI products, and this conclusion holds at upstream and processing levels, taking into account the costs directly related to production; 4) All organic products and almost all PDO and PGI products analysed benefit from a positive quality rent; 5) At upstream level and processing level, the relative weight of intermediate consumption in the cost structure is lower for organic products than for reference products.
摘要本文讨论了食品质量计划(FQS)产品与参考产品相比的盈利能力问题,参考产品被定义为没有质量标签的类似产品。我们通过考虑价值链的水平(上游、加工和下游)、行业(植物、动物、海鲜)和FQS的类型(PGI、PDO、有机)来处理这个问题。我们收集了在选定的欧洲国家以及泰国和越南生产的几种产品的原始数据。通过使用两个可比指标:价格溢价和净价格溢价(包括成本差异),可以根据价值链水平、行业和FQS进行比较。得出以下主要结论:1)无论生产水平、FQS类型或行业如何,FQS产品的价格都高于参考产品;2) FQS产生的价格溢价在价值链上没有差异,在不同行业(植物、动物或海鲜/鱼类)之间也没有差异;3) 有机产品的价格溢价明显高于PGI产品,考虑到与生产直接相关的成本,这一结论在上游和加工层面成立;4) 所有有机产品以及几乎所有分析的PDO和PGI产品都受益于正的质量租金;5) 在上游层面和加工层面,有机产品的中间消费在成本结构中的相对权重低于参考产品。
