The main goal of this study is to investigate the characteristics and determinants of rural non-agricultural activities using country representative household survey. This study is based on 14,616 sampled households which was collected from the four main regions of Ethiopia, namely Tigray, Amhara, Oromia and SNNPR which represent more than 90% of the population of Ethiopia. Descriptive statistics and probit model were implemented for the analysis of the study. The study revealed that non-agricultural participation ranges from 17 to 37% in Amhara and SNNPR regions, respectively. The main non-agricultural activities of Ethiopia covers major economic sectors were manufacturing (brewing traditional alcohols and grain milling among others), trade activities (whole sale and retail trade) and service activities (transport, carpentry, repair service and small restaurants among others). The determinants of rural non-agricultural activities include lack of access to agricultural land, low/volatile earnings and social/economic independence. Majorly, lack of market opportunities, limited access to credit, poor access to road and lack of education were most prominent. It was recommended that rural infrastructure development is critically relevant for facilitating the promotion of rural non-agricultural activity of Ethiopia. Key words: Non-agricultural activity, determinants, households, Ethiopia, Probit model.
本研究的主要目的是利用具有国家代表性的家庭调查来调查农村非农业活动的特征和决定因素。本研究基于埃塞俄比亚四个主要地区的14616个抽样家庭,即提格雷、阿姆哈拉、奥罗米亚和SNNPR,这些地区占埃塞俄比亚人口的90%以上。采用描述性统计和概率概率模型对研究进行分析。研究显示,阿姆哈拉和SNNPR地区的非农业参与率分别为17%至37%。埃塞俄比亚的主要非农业活动涵盖主要经济部门,包括制造业(酿造传统酒精和谷物加工等)、贸易活动(整体销售和零售贸易)和服务活动(运输、木工、维修服务和小餐馆等)。农村非农业活动的决定因素包括无法获得农业用地、收入低/不稳定以及社会/经济独立。主要是缺乏市场机会、获得信贷的机会有限、道路交通不便和缺乏教育。有人建议,农村基础设施的发展对于促进埃塞俄比亚农村非农业活动至关重要。关键词:非农业活动,决定因素,家庭,埃塞俄比亚,Probit模型。

As the independent Benin's first export crop, oil palm continues to play an important role in the Beninese economy and society despite the decline in its production that has begun since the 1970s. It is present in most cropping systems throughout southern Benin. The objective of this article is, on the one hand, to assess the level of technical efficiency of oil palm fruit processing units in South-East Benin and, on the other hand, to analyze the determinants of this technical efficiency. The so-called "two-step" method was used, which consists of using a Data Envelopment Analysis (DEA) model for the analysis of technical efficiency scores followed by a Tobit regression model to analyze the determinants of technical efficiency. The data used were collected in 2018 within the Adja-Ouere municipality. The results obtained show that the average technical efficiency score of the processing units is 0.891, which means that it is still possible to improve the production. The analysis of the determinants of technical efficiency showed that variables such as membership to an agricultural producer organization and the number of direct relatives involved in the processing activity improve the technical efficiency of oil palm fruit processing units. Key words: Oil palm fruit processing, the so-called "two-step" method, data envelopment analysis, Tobit model, Benin.
作为贝宁独立后的第一种出口作物,尽管自20世纪70年代开始产量下降,但油棕仍在贝宁经济和社会中发挥着重要作用。它存在于整个贝宁南部的大多数种植系统中。本文的目的一方面是评估贝宁东南部油棕果加工单位的技术效率水平,另一方面是分析这种技术效率的决定因素。采用“两步法”,即采用数据包络分析(DEA)模型对技术效率得分进行分析,采用Tobit回归模型对技术效率的影响因素进行分析。使用的数据是2018年在阿贾维雷市收集的。结果表明,各加工单元的平均技术效率得分为0.891,表明仍有提高生产的可能。对技术效率决定因素的分析表明,诸如农业生产者组织的成员资格和参与加工活动的直系亲属数量等变量提高了油棕果加工单位的技术效率。关键词:油棕果加工,所谓的“两步法”,数据包络分析,Tobit模型,贝宁

An agroforestry land use system aimed at improving the productivity of smallholder dairy farms using Calliandra calothyrsus and Sesbania sesban shrubs as feed supplements was introduced to semi-commercial SDFs in Meru, Kenya, as part of a field trial. The objective of this study was to assess the impact of using the C. calothyrsus and S. sesban on family income and livelihoods during the 16-month trial period. Eighty farmers randomly allocated to four groups (nutrition, reproduction, combined nutrition and reproduction, and a comparison group) were enrolled in this study. The nutrition intervention included nutritional management advice and provision of 150 C. calothyrsus seedlings and 150 S. sesban seedlings to each farm. Farms were visited every 1-2 months during the trial to collect data on milk production and feeding practices during the previous day. Seventy of these farms completed the trial and were interviewed post-intervention. Partial budget analysis of their farms was done by comparing changes in average monthly profits (from milk) and feeding costs/cow for the first 6 months and last 6 months of the intervention. Focus group discussions were used to collect qualitative information on livelihood effects from the trial. There was a KES 2,380.3 (USD 23.5) increase in average monthly profit/cow in the nutrition group comparing the first and last 6 months of the trial, representing a 68.8% improvement (p = 0.02). Average feeding costs significantly decreased across all groups over the trial period. Knowledge on dairy cow nutrition, level of confidence on calf management, and feeling of empowerment to raise calves/heifers to achieve first calving by 27 months were higher among farmers in the nutrition and combined groups than farmers in the other groups. There were positive direct and indirect impacts on the income and livelihoods of farmers in the two groups receiving nutritional interventions. Agroforestry, using C. calothyrsus and S. sesban shrubs can improve household livelihoods if adopted by SDFs in Kenya. Key words: Smallholder dairy, agroforestry, partial budget analysis, leguminous shrubs.
作为田间试验的一部分,在肯尼亚Meru的半商业化sdf中引入了一种农林复合土地利用系统,目的是提高使用Calliandra calothyrsus和Sesbania sesban灌木作为饲料补充的小农奶牛场的生产力。本研究的目的是在16个月的试验期内,评估使用卡罗茜草和山楂对家庭收入和生计的影响。80名农民随机分为营养组、繁殖组、营养与繁殖联合组和对照组。营养干预措施包括提供营养管理建议,并向每个农场提供150株卡罗思树幼苗和150株山菜幼苗。在试验期间,每1-2个月访问一次农场,收集前一天的产奶量和饲养方法数据。其中70个农场完成了试验,并在干预后接受了采访。通过比较干预的前6个月和最后6个月平均月利润(来自牛奶)和饲养成本/奶牛的变化,对他们的农场进行了部分预算分析。通过焦点小组讨论收集试验对生计影响的定性信息。与试验的前6个月和后6个月相比,营养组每头奶牛的月平均利润增加了2380.3 KES(23.5美元),提高了68.8% (p = 0.02)。试验期间各组的平均饲养成本显著降低。与其他组相比,营养组和联合组的农民对奶牛营养的了解程度、对小牛管理的信心水平以及对在27个月前饲养小牛/小母牛以实现首产犊的授权感更高。接受营养干预的两组农民的收入和生计都受到了直接和间接的积极影响。农林业,如果肯尼亚的sdf采用,可以利用卡罗thyrsus和ssesban灌木改善家庭生计。关键词:小农奶牛场,农林复合,部分预算分析,豆科灌木

Microfinance is proposed to be an efficient and viable means to poverty alleviation in the developing world, but there has been little empirical study on the impacts of microfinance banks. This study examines the impact of Rima Microfinance Bank on beneficiaries’ income and poverty in Goronyo Local Government Area of Sokoto State, Nigeria. A multistage-sampling technique was used to draw the sample and a structured questionnaire was used for data collection. The data was analysed using descriptive statistics (means, frequency, and percentages) and Foster, Greer and Thorbecke (FGT) poverty index. The result revealed that the beneficiaries had a mean per capita income of N47,489.19 before and N115,678 after using the Rima Microfinance credit facility. The result of the FGT poverty incidence reduces by 6%. This is reflected by the reduction in poverty depth and severity significantly after the Rima microfinance intervention in the form of agricultural input credit facilities. The study recommends a microfinance policy that will ease more access to credit as well as ensuring efficient utilization of acquired inputs through effective monitoring for better productivity, income and poverty reduction among rural dwellers. Key words: Rima-Microfinace, impact, income, poverty, beneficiaries.
小额信贷被认为是发展中国家有效和可行的扶贫手段,但对小额信贷银行影响的实证研究很少。本研究考察了Rima小额信贷银行对尼日利亚索科托州Goronyo地方政府地区受益人收入和贫困的影响。采用多阶段抽样技术抽取样本,采用结构化问卷进行数据收集。使用描述性统计(均值、频率和百分比)和福斯特、格里尔和托贝克(FGT)贫困指数对数据进行分析。结果显示,受益人在使用Rima小额信贷工具之前的人均收入为47,489.19奈拉,在使用Rima小额信贷工具之后的人均收入为115,678奈拉。FGT的结果是贫困发生率降低了6%。这反映在Rima以农业投入信贷设施的形式进行小额信贷干预后,贫困的深度和严重程度显著降低。该研究建议制定一项小额信贷政策,通过有效监测提高农村居民的生产力、收入和减贫,使更多的人能够获得信贷,并确保有效利用获得的投入。关键词:rima - microfinance,影响,收入,贫困,受益人

Impact of soil and water conservation technology adoption on smallholder farms in South-Western Uganda 水土保持技术对乌干达西南部小农农场的影响
Pub Date : 2019-09-30 DOI: 10.5897/jdae2018.0918

For countries where the agricultural sector supports a majority of the population as in Uganda, the link between poverty and land degradation is of great significance. Soil and water conservation technologies are a recommended means of reducing degradation rates. However, ex-ante and ex-post analyses of the impact of these technologies remain few. Using survey data collected from 338 randomly selected households in the Kabale district of South-Western Uganda, this study used a Tradeoff Analysis for Multi-Dimensional Impact Assessment (TOA-MD) model to analyze the impact of adoption on household agricultural income and poverty levels. In the survey, households in the district either had or had not adopted the soil and water conservation technologies that had been disseminated. Results indicate that the simulated range of adoption rates is between 55 and 85%, with a potential to increase to about 90% amongst households with higher non-farm income.  Households are also anticipated to benefit from adoption of soil and water conservation technologies through higher income from farming and poverty reduction; adoption is positively correlated with household non-farm income. Increased access to inputs, credit and improvement in infrastructure are recommended, especially for low income households. Dissemination of soil and water conservation technologies needs to be combined with other income generating measures in order to have a bigger impact on household welfare. Key words: Trade-off analysis, tradeoff analysis for multi-dimensional impact assessment (TOA-MD), soil and water conservation, Uganda, adoption impact, household welfare, smallholder farms.
对于像乌干达这样农业部门支持大多数人口的国家来说,贫困与土地退化之间的联系具有重要意义。水土保持技术是降低退化率的一种推荐方法。然而,对这些技术影响的事前和事后分析仍然很少。本研究使用从乌干达西南部卡巴莱区338个随机选择的家庭收集的调查数据,使用多维影响评估的权衡分析(TOA-MD)模型来分析收养对家庭农业收入和贫困水平的影响。在调查中,该地区的家庭要么采用了已经传播的水土保持技术,要么没有采用。结果表明,模拟的收养率范围在55%至85%之间,在非农收入较高的家庭中,收养率有可能提高到90%左右。通过提高农业收入和减贫,预计家庭也将受益于水土保持技术的采用;收养与家庭非农收入呈正相关。建议增加获得投入、信贷和改善基础设施的机会,特别是对低收入家庭而言。水土保持技术的传播需要与其他创收措施相结合,以便对家庭福利产生更大的影响。关键词:权衡分析,多维影响评估的权衡分析(TOA-MD),水土保持,乌干达,收养影响,家庭福利,小农户。

Following institutionalisation of certified organic agriculture in Uganda in 2002, more farmers have adopted organic pineapple farming to boost their economic livelihoods. However, farmers have continued to engage in the less profitable conventional market due to organic market’s limited capacity to absorb all their produce. This study seeks to examine organic pineapple farmers’ market choices, improve the empirical understanding of factors determining these choices and how they relate to the success of organic pineapple marketing in Uganda. Data was obtained from a random sample of 116 organic pineapple farmers from central region and three pineapple export companies, in cross-sectional household and key informant surveys. Descriptive statistics revealed that 68% of the farmers sold organic pineapples via both organic and conventional market channels at the same time. The study employed a conditional logit model to explain the factors influencing organic farmers’ market channel choice which established that organic and conventional market price differences in peak and lean seasons, pineapple harvests and losses significantly influenced farmers’ market choice. Farmers’ organic market share can be increased by policy makers’ promotion of local and regional organic market outlets and value addition at farmer and company levels. Key words: Organic pineapple, market choice, Uganda.
2002年,乌干达认证有机农业制度化后,越来越多的农民采用有机菠萝种植来提高他们的经济生计。然而,由于有机市场吸收所有农产品的能力有限,农民继续参与利润较低的传统市场。本研究旨在检验有机菠萝农民的市场选择,提高对决定这些选择的因素的实证理解,以及它们与乌干达有机菠萝营销成功的关系。数据是从来自中部地区的116名有机菠萝农民和三家菠萝出口公司的随机样本中获得的,在横断面家庭和关键信息人调查中。描述性统计显示,68%的农民同时通过有机和传统市场渠道销售有机菠萝。本研究采用条件logit模型解释了影响有机农户市场渠道选择的因素,结果表明,丰、淡季节的有机和常规市场价格差异、菠萝的收成和损失显著影响了农户的市场选择。政策制定者可以通过促进地方和区域有机市场渠道以及农民和公司层面的增值来提高农民的有机市场份额。关键词:有机菠萝,市场选择,乌干达。

The objective was to characterize the farming systems of AGP-II districts and identify production constraints. We investigate how historical trends have influenced the farming system, using data from desk review surveys, semi-structured interviews, focus-group discussions; key informant discussions and observations; by investigating two sample districts of AGP II; these were Ambo and Girar Jarso of Oromia regional state of Ethiopia. From each district two PAs were selected randomly applying stratified sampling techniques for AGP II districts. Findings indicate a high disparity in the characterization of wealth and status; that requires intervention to minimize gaps with agricultural technologies; the micro finance institutions have a long way to go to support the input service thought it has increased from 5% in 2012 to 8%in 2017 credit supply. Farmer training centers 65% of them aren’t  functional in Ambo district. Average yield per hectare in kg were found 3,700, 3,101, 2,800, 2,100 were for maize, sorghum, wheat and barley respectively; while the average market price per kg was 7 Ethiopian Birr which was 0.31 USD (June/2017 average exchange rate 22.91 Birr/1 USD). While tef, chickpea and lentil was 1,801, 2,300 and 1,800 respectively, with average market price per kg was 20, 24, and 21 Ethiopian Birr which was 0.9, 1.1 and 0.9 USD. So; intervention of technologies has to consider profitability and other necessary parameters. Key words: Farming system, wealth status, Agricultural Growth Program-II (AGP-II), food security, agricultural technologies.
本文介绍了农业增长计划II中的农业系统动力学,并应用了PRA模型。目的是描述AGP-II地区的农业系统,并确定生产限制。我们使用案头审查调查、半结构化访谈和焦点小组讨论的数据,调查历史趋势如何影响农业系统;关键线人的讨论和意见;通过调查AGP II的两个样本区;他们是埃塞俄比亚奥罗米亚州的Ambo和Girar Jarso。从每个地区随机选择两个PA,采用AGP II地区的分层抽样技术。调查结果表明,在财富和地位特征方面存在很大差异;这就需要采取干预措施,最大限度地缩小与农业技术之间的差距;小额金融机构在支持投入服务方面还有很长的路要走,认为投入服务已经从2012年的5%增加到2017年的8%。其中65%的农民培训中心在安博区没有运作。玉米、高粱、小麦和大麦的平均每公顷产量分别为3700、3101、2800和2100公斤;而每公斤的平均市场价格为7埃塞俄比亚比尔,即0.31美元(2017年6月的平均汇率为22.91比尔/1美元)。而四氟、鹰嘴豆和扁豆分别为1801、2300和1800,每公斤的平均市场价格分别为20、24和21埃塞俄比亚比尔,分别为0.9、1.1和0.9美元。所以技术干预必须考虑盈利能力和其他必要的参数。关键词:农业制度,财富状况,农业增长计划II(AGP-II),粮食安全,农业技术。

The purpose of this study is to evaluate rural household’s food and income diversification decisions in face of climate change adaptation strategies using advances in choice-based experiment. Several studies have focused on general and specific food values using the balanced incomplete block design; but fewer studies have been devoted to study rural household food and income diversification decisions via the lens of balanced incomplete Latin square design (BILSD). The BILSD was used to design questionnaire served in data collection. For each question, respondents were asked to choose his best and worst coping strategies. Mixed logit model was used to data. Results reveal that agricultural production, livestock products and remaining stock from previous harvest were the most important sources of food; while the sale of agricultural product followed by the sale of garden product, picking and the sale wild fruits and leafy vegetables, small business, crafting, project transfer, the sale of firewood and straw and the sale of livestock product were the most important sources of income. Results suggest that agricultural production, livestock production and stock from previous harvest and as well as the sale of agricultural product, the sale of garden product, picking and the sale wild fruits and leafy vegetables, small business, crafting, project transfer, the sale of firewood and straw and the sale livestock product are the optimal combination food and income diversification decisions to enhance rural household resilience building capacity. Results finally suggest that collective decision made about food and income diversification decisions is more welfare enhancing that individual decision. Key words: Food and income diversification decisions, rural household, choice experiment, climate change adaptation strategies.
本研究的目的是利用基于选择的实验进展,评估面对气候变化适应策略的农村家庭的粮食和收入多样化决策。一些研究使用平衡不完全块设计来关注一般和特定的食物价值;但很少有研究专门通过平衡不完全拉丁方设计(BILSD)的视角来研究农村家庭的食物和收入多样化决策。BILSD用于设计用于数据收集的问卷。对于每个问题,受访者都被要求选择最佳和最差的应对策略。数据采用混合logit模型。结果表明,农业生产、畜产品和以前收获的剩余牲畜是最重要的粮食来源;农产品销售,其次是花园产品销售、野生水果和叶菜的采摘和销售、小企业、手工制作、项目转让、木柴和稻草的销售以及畜产品的销售是最重要的收入来源。结果表明,农业生产、畜牧业生产和前一次收获的库存以及农产品销售、花园产品销售、野生水果和叶菜采摘和销售、小企业、手工制作、项目转让、,销售木柴和秸秆以及销售畜产品是粮食和收入多样化的最佳组合决策,可以增强农村家庭的抗灾能力建设。结果最后表明,关于食物和收入多样化的集体决策比个人决策更能提高福利。关键词:粮食和收入多样化决策,农村家庭,选择实验,气候变化适应战略。

This study aims to analyse the factors that influence the selection of governance structures by rice producers and processors in Benin. Unlike previous studies, the factors that influence the selection of governance structures are identified simultaneously for both producers and processors of paddy. Data were collected in Benin from about 300 producers and 140 processors of paddy randomly selected. The results indicate that 78% of producers and 92% of the processors use spot market for paddy transaction. Around a quarter of producers use at least two governance structures to sell paddy. Producers and processors belonging to an innovation platform are more likely to use formal contracts in their transactions. Also, producers and processors are more likely to use credit payment mechanism with formal contract. The findings suggest that innovation platforms can be used to facilitate contractual relationships between paddy producers and processors. Key words: Multivariate probit, market dynamics, African rice value chains, governance mechanisms.
本研究旨在分析影响贝宁大米生产商和加工商选择治理结构的因素。与以往的研究不同,影响治理结构选择的因素是水稻生产者和加工者同时确定的。数据是从贝宁随机选择的大约300个水稻生产者和140个水稻加工商那里收集的。结果表明,78%的生产者和92%的加工商使用现货市场进行水稻交易。大约四分之一的生产者至少使用两种治理结构来销售水稻。属于创新平台的生产商和加工商更有可能在交易中使用正式合同。此外,生产商和加工商更有可能使用具有正式合同的信用支付机制。研究结果表明,创新平台可以用来促进水稻生产商和加工商之间的合同关系。关键词:多元概率、市场动态、非洲大米价值链、治理机制。

This study was to examine factors affecting adoption of improved Jalenea potato variety in the study area in the year 2017. Primary data for the study were collected from respondents using structured interview schedule. Focus group discussions were conducted with farmer and stakeholders. The data were analyzed using mean, percentage, frequency, chi-square test, and T-test. Binary logistic regression analysis was employed to identify factors affecting adoption of the variety. Age of the household negatively and significantly affected adoption whereas sex of the household head positively and significantly affected the adoption. Non-farm activity and farm income had positive and significant effect on adoption. Advisory service from extension agents, attending training and field day, and membership of seed multiplication cooperative had also positively and significantly affected adoption of improved Jalenea potato variety. The finding highlighted the importance of institutional support in the area of extension; training and farmers’ cooperatives. Therefore, policy and development interventions should give emphasis to improving institutional support system. Key words: potato, binary loggit, determinants, odds ratio, management practices.
本研究旨在探讨2017年影响研究区马铃薯改良品种采用的因素。本研究的主要数据是使用结构化访谈时间表从受访者中收集的。与农民和持份者进行焦点小组讨论。采用均数、百分比、频率、卡方检验和t检验对数据进行分析。采用二元logistic回归分析确定影响品种采收的因素。家庭年龄负向显著影响收养行为,户主性别正向显著影响收养行为。非农活动和农业收入对采用率有显著的正向影响。推广代理商的咨询服务、参加培训和田间日以及种子繁殖合作社的成员资格也对马铃薯改良品种的采用产生了积极而显著的影响。调查结果突出了在推广领域提供机构支助的重要性;培训和农民合作社。因此,政策和发展干预应注重完善体制支持体系。关键词:马铃薯,二进制对数,决定因素,优势比,管理实践。
