Abstract. The Purpose of the study was to analyse the effects of access to tractor service on technical efficiency among small-scale maize farmers following the implementation of Masibuyele Emasimini programme in Mpumalanga Province. Data collection was carried out in the districts of Mpumalanga province and these are: Ehlanzeni, Nkangala and Gert Sibande. Purposive sampling technique was used in identifying the three districts. A total of 101 small-scale maize farmers were purposively selected from the districts and used for the study. The study concluded that small-scale maize farmers do have access to tractor service rendered by the Masibuyele Emasimini programme, with 73% of farmers in Ehlanzeni and 60% in both Nkangala and Gert Sibande district that have access to the service, compared to 27% and 40% without access. Results indicate that there are socio-economic factors influencing small-scale maize farmers’ access to tractor service, for example, irrigation, inter alia. The Cobb-Douglas model found access to tractor service to be negative and insignificant in both Ehlanzeni and Nkangala district. The variable was however positive (although insignificant) in Gert Sibande. The study recommends that modern irrigation systems (preferably, sprinkler) should be provided as part of the programmes’ input list to contribute towards efficient maize production.
摘要本研究的目的是分析在姆普马兰加省实施Masibuyele Emasimini方案后,获得拖拉机服务对小规模玉米农民技术效率的影响。数据收集工作在姆普马兰加省的地区进行,这些地区是:埃伦泽尼、恩坎加拉和格特西班德。采用有目的抽样方法对三个地区进行鉴定。共有101名小规模种植玉米的农户参与了研究。研究得出的结论是,小规模种植玉米的农民确实可以获得Masibuyele Emasimini项目提供的拖拉机服务,Ehlanzeni地区73%的农民可以获得该服务,Nkangala和Gert Sibande地区60%的农民可以获得该服务,而无法获得该服务的农民分别为27%和40%。结果表明,影响玉米小农获得拖拉机服务的社会经济因素,如灌溉等。柯布-道格拉斯模型发现,在Ehlanzeni和Nkangala地区,获得拖拉机服务的机会是负面的,而且微不足道。然而,Gert Sibande的变量为正(尽管不显著)。该研究建议,应该提供现代灌溉系统(最好是洒水系统)作为项目投入清单的一部分,以促进有效的玉米生产。

Farming has been considered as main source of income for rural households in Nigeria, despite their involvement in other income generating activities. Focusing on income derivable from farming alone may be partially responsible for the ineffective poverty reduction strategies in Nigeria. Using the National Living Standard Survey data collected by the National Bureau of Statistics, this paper investigated the composition and determinants of non-farm incomes of rural households in Nigeria. The results show that the share of farm, non-farm wage (NFW)- and self-employment (NFS) incomes in total household incomes were 24.3%, 43.0% and 23.7% respectively. Households whose heads are male (0.647), had formal education (0.522), increased the likelihood of households’ participation in NFW activities, while access to credit (-0.307) and having larger farm size (-0.221) decreased it. Access to credit (0.379); community participation (0.103); larger family size (0.193) and possession of capital assets (0.069) increased the likelihood of participation in NFS-employment activities, while having larger farm size (-0.211) decreased it. The study concludes that policy targeting poverty reduction should focus on providing enabling environment for poor households’ access to non-farm activities in the study area.
农业一直被认为是尼日利亚农村家庭的主要收入来源,尽管他们也从事其他创收活动。只注重农业收入可能是尼日利亚减贫战略无效的部分原因。本文利用国家统计局收集的全国生活水平调查数据,调查了尼日利亚农村家庭非农业收入的构成和决定因素。结果表明,农业收入、非农工资收入和自营职业收入占家庭总收入的比例分别为24.3%、43.0%和23.7%。户主为男性的家庭(0.647)、受过正规教育的家庭(0.522)增加了家庭参与农村妇女活动的可能性,而获得信贷的家庭(-0.307)和农场规模较大的家庭(-0.221)则降低了家庭参与农村妇女活动的可能性。获得信贷(0.379);社区参与(0.103);较大的家庭规模(0.193)和拥有资本资产(0.069)增加了参与nfs就业活动的可能性,而较大的农场规模(-0.211)则降低了参与nfs就业活动的可能性。研究得出结论,减贫政策应侧重于为研究地区贫困家庭参与非农业活动提供有利环境。

Suboptimal land management practices (SLM) are degrading soils and undermining food security. Despite this, there is scant information regarding households’ decision towards the effect of food security on SLM technologies. This paper, therefore, measured food security status and assessed the effect of food security on SLM technologies. Structured interview schedule was used to gather data for this study. A three-stage sampling procedure was employed for this study. Two out of the four ADP zones were randomly selected in the first stage. This was followed by a proportionate selection of 30 villages from the two selected zones. Lastly, ten farming households each, were picked randomly from the chosen villages to make up a sample size of 300 farming households. The result revealed that the calculated MPCFE was ₦4218.587 and the proportion of food secure and food insecure households are 37.7% and 62.3% respectively. The findings affirmed that much opportunities exist for increasing productivity and income through increased adoption of SLM technologies among the food insecure households when compared with their food secure counterparts. The R2 value of 29.8% suggests that the explanatory variables explained about 30% of the variation in the explained variable. Furthermore, the factors influencing SLM technologies of households are food security status, family size, monthly income and plot size. This study provides useful insight into policies and actions taken by farmers and government to mitigate the effects of suboptimal use of SLM technologies for improved production and food security. Policies favoring increased plot size should be vigorously pursued.
次优土地管理做法(SLM)正在使土壤退化并破坏粮食安全。尽管如此,关于家庭对粮食安全对SLM技术影响的决定的信息很少。因此,本文测量了粮食安全状况,并评估了粮食安全对SLM技术的影响。本研究采用结构化访谈表收集数据。本研究采用三阶段抽样程序。在第一阶段,从四个ADP区中随机选择两个。随后从两个选定的地区按比例选出30个村庄。最后,从选定的村庄中随机抽取10户农户,构成300户农户的样本量。结果显示,计算的MPCFE为4218.587奈拉,粮食安全家庭和粮食不安全家庭所占比例分别为37.7%和62.3%。调查结果证实,与粮食安全家庭相比,粮食不安全家庭通过更多地采用SLM技术来提高生产力和收入的机会很大。R2值为29.8%,表明解释变量解释了被解释变量30%左右的变异。农户的粮食安全状况、家庭规模、月收入和小区面积是影响农户SLM技术的主要因素。这项研究为农民和政府采取的政策和行动提供了有用的见解,以减轻非最佳使用SLM技术对改善生产和粮食安全的影响。应该大力推行有利于增加土地面积的政策。

Artificial Insemination (AI) in poultry production is a veritable technique in solving the problem of breeding and meeting the increasing demand. This study assesses the economics of artificial insemination in broiler production among sixty randomly selected broiler farmers in Nigeria. The analytical techniques employed include descriptive statistics, gross margin analysis, and stochastic frontier.  The result discovered that most of the farmers are male and are at their prime age. Majority of the livestock farmers have some form of formal education and a minimum of 5 (five) year experience in poultry farming. The capital was mostly sourced from the bank. Majority of the farmers has a stock size of more than 25,000 birds. They have a gross margin of N341, 933,406. Only 20% of gross income was used for operating expenses with a return on capital invested of 4.3. The mean technical efficiency was 80.70%. Feed, vaccine and stock size were statistically significant in determining efficiency while education and extension visits are the statistically significant variable influencing technical inefficiency. It is therefore recommended that affordable and accessible input, as well as training should be made available to farmers to achieve self-sufficiency and improve the economy.
家禽生产中的人工授精技术是解决育种问题和满足日益增长的需求的一项名副其实的技术。本研究评估了尼日利亚60个随机选择的肉鸡养殖户在肉鸡生产中人工授精的经济性。采用的分析技术包括描述性统计、毛利率分析和随机前沿。结果发现,农民以男性居多,处于壮年期。大多数畜牧农民都受过某种形式的正规教育,至少有5年的家禽养殖经验。资金主要来自银行。大多数养殖户的养禽规模都在2.5万只以上。他们的毛利率为341,933,406奈拉。只有总收入的20%用于运营费用,资本投资回报率为4.3。平均技术效率为80.70%。饲料、疫苗和存栏量是决定效率的统计显著变量,而教育和推广访问量是影响技术效率的统计显著变量。因此,建议向农民提供负担得起和容易获得的投入以及培训,以实现自给自足和改善经济。

Trends in Quinoa Adoption in Marginal Areas, Economic Viability, and Policy Outlook 边缘地区采用藜麦的趋势、经济可行性和政策展望
Pub Date : 2020-11-08 DOI: 10.17306/j.jard.2020.01351

Global demand for quinoa has substantially grown seemingly due to the rich nutritional ingredients in quinoa grain and its resilience to unfavorable and harsh biotical stresses and environmental factors prevalent in marginal environments. Research evidence suggest that global quinoa production as well as the number of quinoa-producing countries have been substantially increased throughout the last few years. With intensive research trails and tests underway in new countries across the world, especially in the Middle East and North Africa (MENA) region, researchers and policymakers are determined to upscale its commercial production. However, little is known about its economic viability to substantiate the adoption and ultimately the sustainability of quinoa production. The economic analysis carried out in this study suggests that quinoa can be highly profitable, but its economic viability largely depends on the availability of high-yielding verities, best management practices through demand-driven extension services, and reliable market information on local demand and prices. Under the most-likely production scenario, estimated net profit can reach up to AED 6,059 ($1,651) per hectare. Given the lack of quality data, the estimated net gains are simulated to assess the level of sensitivity due to potential uncertainties and volatility in key variables and assumptions. After 10,000 iterations, the results from Monte Carlo simulation reveals that the average value of simulated net gains is about AED 8,265 per hectare with no significant chances of negative profits.
全球对藜麦的需求大幅增长,这似乎是因为藜麦谷物中含有丰富的营养成分,能够抵御不利和恶劣的生物胁迫以及边缘环境中普遍存在的环境因素。研究证据表明,全球藜麦产量以及藜麦生产国的数量在过去几年中大幅增加。随着世界各地新国家,特别是中东和北非地区正在进行密集的研究和测试,研究人员和政策制定者决心提升其商业生产。然而,人们对其经济可行性知之甚少,无法证实藜麦生产的采用和最终的可持续性。这项研究中进行的经济分析表明,藜麦可能具有很高的利润,但其经济可行性在很大程度上取决于高产率、通过需求驱动的推广服务提供的最佳管理实践,以及当地需求和价格的可靠市场信息。在最有可能的生产情况下,预计净利润可达每公顷6059迪拉姆(1651美元)。鉴于缺乏高质量的数据,对估计的净收益进行了模拟,以评估由于关键变量和假设的潜在不确定性和波动性而导致的敏感性水平。经过10000次迭代,蒙特卡洛模拟的结果表明,模拟净收益的平均值约为每公顷8265迪拉姆,没有显著的负利润机会。

Climate change has brought about irregularity in pattern and intensity of climatic variables such as rainfall and temperature that are important in crop production; making planning in agriculture difficult. The importance of cassava in the diet of Nigerian and its industrial use necessitate the need to examine the effects of climatic variability on cassava production. Secondary data obtained from Nigerian Meteorological Agency (NIMET) were used for the study. Analysis of Variance and Error Correction model were utilized.  The study showed that the rainforest zone had the highest averages of annual rainfall (1709mm) and relative humidity (82.1%) while the Sahel savannah had the highest mean annual temperature (35.3oC). The variability in annual rainfall and relative humidity was low in the rainforest zone. The study showed that the rainforest zone had the least dispersion of average annual relative humidity (2.06%) while the guinea savannah had highest dispersion (4.68%). The average cassava output from the agro-ecological zones was 49,118,871MT per year. Rainforest and guinea savannah accounted for 56.3% and 41.9% of total cassava output respectively. There were significant variations in the climatic variables (rainfall and temperature) among the agro-ecological zones but not significant among the years (p>0.05).  The annual rainfall and solar radiation were the factors that influenced cassava output in all the agro-ecological zones. The need for affordable irrigation by cassava farmers and the adoption of Climate-Smart Agriculture are recommended to boost cassava production in Sudan savannah and Sahel savannah.
气候变化导致气候变量的模式和强度不规则,如对作物生产至关重要的降雨量和温度;使得农业规划变得困难。木薯在尼日利亚人饮食中的重要性及其工业用途需要研究气候变化对木薯生产的影响。研究使用了从尼日利亚气象局(NIMET)获得的二次数据。采用方差分析和误差修正模型。研究表明,热带雨林的年平均降雨量(1709mm)和相对湿度(82.1%)最高,而萨赫勒大草原的年平均温度(35.3摄氏度)最高。热带雨林地区的年降雨量和相对湿度变化较小。研究表明,热带雨林区的年均相对湿度分布最小(2.06%),几内亚稀树草原区的年均平均相对湿度分布最高(4.68%),农业生态区的平均木薯产量为49118871MT。雨林和几内亚草原分别占木薯总产量的56.3%和41.9%。气候变量(降雨量和温度)在农业生态区之间存在显著差异,但在年份之间不显著(p>0.05)。年降雨量和太阳辐射是影响所有农业生态区木薯产量的因素。建议木薯农民需要负担得起的灌溉,并采用气候智能农业,以提高苏丹大草原和萨赫勒大草原的木薯产量。

The supply of seed yams for intensive yam production is hindered by many constraints, including diseases and pest infestations as well as the unavailability of quality planting material. The combination of tissue culture and aeroponics system is perceived to be the way towards clean and adequate supply of seed yam for enhanced yam production. However, the system is considered as expensive for any individual to implement. In order to encourage private sector to participate in this venture, the economic analysis determining the feasibility and viability of using aeroponics in seed yam production was performed. Using data from established tissue culture and aeroponics system in Ghana, the fixed cost and variable cost parameters as well as production costs were obtained. Results revealed that total cost of building aeroponics structure amounted to GH₵ 94,178.00 (USD 17,938.70). Annual cost of aeroponics structure was GH₵ 9,417.82 (USD 1,793.87). Annual total cost of production totalled GH₵ 204,391.75 (USD 38,931.61). Annual net revenue was GH₵ 75,888.00 (USD 14,454.86). Payback period was 15 months and benefit cost ratio was 1.4. Aeroponics system for seed yam production is therefore profitable since short period would be needed to recoup investment. For food security and creation of workplaces, government could partner with the private sector in the establishment of aeroponics systems to increase yam production and export.
用于集约化生产的种薯的供应受到许多限制,包括病虫害以及缺乏优质种植材料。组织培养和气培系统的结合被认为是清洁和充足供应种子的途径,以提高山药产量。然而,该系统被认为对任何个人来说都是昂贵的。为了鼓励私营部门参与这一合资企业,进行了经济分析,以确定在种薯生产中使用气培技术的可行性和可行性。利用加纳建立的组织培养和气培系统的数据,获得了固定成本和可变成本参数以及生产成本。结果显示,建造气培结构的总成本为94178.00 GH(17938.70美元)。气培结构年成本为9417.82 GH(1793.87美元)。年总生产成本为204391.75 GH(38931.61美元)。年度净收入为75888.00 GH(14454.86美元)。回收期为15个月,效益成本比为1.4。因此,用于种薯生产的气培系统是有利可图的,因为需要很短的时间来收回投资。为了粮食安全和创造工作场所,政府可以与私营部门合作,建立气培系统,以增加山药的生产和出口。

Smallholder farmers face multiple constraints in accessing input markets. This study seeks to understand the dynamics that influence input markets in northern Ghana and the opportunities that exist for smallholder farmers to increase their productivity and welfare. Using a random sample of 448 households, the study applied the probit and non-parametric methods in identifying the factors that influence farmers’ access to input markets and the key constraints faced by them. The results show that access to extension services, access to finance, distance to the nearest input market, and input source are significant factors that would be likely to influence farmers’ access to input markets. Lack of finance, poor road network, and low prices of output are the main critically ranked constraints limiting farmers’ access to input markets. Policy initiatives should be geared toward strengthening extension service delivery, farmer education on inputs, improving feeder roads, and encouraging private sector participation in input markets. Available opportunities to leverage on and improve farmers’ access to input markets include the governments’ input subsidy programmes, existing large-scale agricultural projects, private agricultural companies with contract farming models, and extensive network of input dealers and aggregators in the communities. These findings are relevant for farmers, input dealers and policy makers working to improve farmers’ access to input markets.
小农户在进入投入市场方面面临多重制约。本研究旨在了解影响加纳北部投入市场的动态,以及小农户提高生产力和福利的机会。该研究使用448户家庭的随机样本,应用概率和非参数方法来确定影响农民进入投入市场的因素以及他们面临的关键制约因素。结果表明,获得推广服务、获得资金、与最近投入市场的距离和投入来源是可能影响农民进入投入市场的重要因素。缺乏资金、糟糕的道路网络和低产出价格是限制农民进入投入市场的主要制约因素。政策举措应着眼于加强推广服务提供、农民投入教育、改善支线道路以及鼓励私营部门参与投入市场。利用和改善农民进入投入市场的现有机会包括政府的投入补贴计划、现有的大型农业项目、具有合同农业模式的私营农业公司,以及社区中广泛的投入经销商和聚合商网络。这些发现与农民、投入品经销商和致力于改善农民进入投入品市场的政策制定者有关。

Consumption is among the key determinants of milk production and profitability. The main purpose of this paper is to present the level of and changes in milk and dairy products consumption in the EU in 2004–2018. Due to changing consumer preferences, the average consumption of milk and milk products in EU countries is on an increase. In turn, Poland witnesses growth in consumption of milk for ripening and processed cheese and yogurt. In 2004–2017, per capita consumption of ice cream, cheese and powdered milk followed a downward trend. In order to examine changes in the consumption of milk and milk products, a forecast was prepared which shows that in 2018–2022, Poland will experience an increase in the average monthly consumption of milk, ice cream and cheese. On the other hand, the EU will report growth in consumption of fresh dairy products, butter, cheese, skim milk and powdered milk, and a decrease in casein consumption.
消费量是牛奶产量和盈利能力的关键决定因素之一。本文的主要目的是介绍2004-2018年欧盟牛奶和乳制品消费的水平和变化。由于消费者偏好的变化,欧盟国家牛奶和奶制品的平均消费量正在增加。反过来,波兰见证了用于成熟和加工奶酪和酸奶的牛奶消费量的增长。2004-2017年,冰淇淋、奶酪和奶粉的人均消费量呈下降趋势。为了研究牛奶和奶制品消费的变化,一项预测显示,在2018-2022年,波兰的牛奶、冰淇淋和奶酪的平均月消费量将增加。另一方面,欧盟将报告新鲜乳制品、黄油、奶酪、脱脂牛奶和奶粉的消费增长,酪蛋白消费减少。

This study was carried out to estimate the extent of food security and its determinants among rural households in Nigeria. Data for this study was obtained from 180 rural households consisting of 1260 members through the use of a structured questionnaire. Data was analyzed with a descriptive technique and a less restrictive multinomial logistic regression model. The result found most rural households to be food insecure as they measure high on the food insecurity scale. Age, gender, marital status, access to credit, dependency ratio, household size, ownership of farmland and farming experience significantly influence food security categories. The study concluded that: female-headed married households were more food secure than male-headed households; an increase in age of household heads makes it more likely to be food secure, and so does access to credit facilities; conversely, an increase in family size and in the dependency ratio makes it less likely to be food secure. The study recommends that there should be provision and proper monitoring of credit facilities to small farmers in other to increase their scale of operation and improve their food security status. Also, adequate attention should be given to policy measures that address family planning in order to reduce the household size to a level the household heads can adequately cater for.
这项研究旨在评估尼日利亚农村家庭的粮食安全程度及其决定因素。本研究的数据是通过使用结构化问卷从180个农村家庭中获得的,其中包括1260名成员。数据采用描述性技术和限制较少的多项逻辑回归模型进行分析。结果发现,大多数农村家庭粮食不安全,因为他们的粮食不安全程度很高。年龄、性别、婚姻状况、获得信贷的机会、抚养比、家庭规模、农田所有权和耕作经验对粮食安全类别有重大影响。研究得出的结论是:女性户主的已婚家庭比男性户主的家庭更有粮食保障;户主年龄的增加使其更有可能获得粮食安全,获得信贷的机会也增加了;相反,家庭规模和抚养比的增加会降低粮食安全的可能性。该研究建议,应向其他地区的小农户提供并适当监测信贷设施,以扩大其经营规模,改善其粮食安全状况。此外,应充分注意解决计划生育问题的政策措施,以便将家庭规模缩小到户主能够充分满足的水平。
