The study characterizes and analyzes the existing farming system and identifies the production and marketing constraints of Cheliya and Ilu Gelan districts with cross-sectional data of 105 sample households.  The farming system of the study areas is characterized as mixed farming systems with 59.1 and 27.44% contribution of crop and livestock, respectively for livelihood activities. From the survey results, disease (96.19%), shortage of grazing land (73.33%), feed shortage (48.57%), shortage of veterinary medicine (20.95%), shortage of water (18.10%) and lack of improved breeds (14.29%) were identified as major important constraints in livestock production. High transaction cost (71.43%), lack of capital (35.24%), lack of market information (23.81%), price and demand fluctuation (21.90%), lack of market linkage (14.29%) and unorganized marketing system (12.38%) were reported as major constraints in livestock marketing. Pests, high cost of inputs, shortage of land, weed infestation, shortage of inputs, low yield, poor quality of seed and poor soil fertility were identified as important crop production constraints. High transaction cost, low price output, lack of market information and lack of market linkage were summarized as major crop marketing constraints. Besides, soil erosion, soil fertility decline, water logging, soil acidity and termite were reported as important constraints in natural resources. Improving livestock productivity through improved breed, forage, control disease and control illegal livestock trade needs attention. Additionally, improving crop productivity through Integrated Pest Management (IPM), improved varieties, minimizing transaction cost, focusing on high value crop, expanding soil and water conservation, strengthening market information and linkage needs urgent concentration for interventions. Key words: Crop, farming system, livestock, natural resource.
本研究利用105个样本户的横截面数据,对切里亚和伊鲁戈兰地区的现有耕作制度进行了特征分析,并确定了生产和销售的制约因素。研究区农作系统为混合农作系统,种植业和畜牧业对生计活动的贡献率分别为59.1%和27.44%。从调查结果来看,疾病(96.19%)、牧场短缺(73.33%)、饲料短缺(48.57%)、兽药短缺(20.95%)、水资源短缺(18.10%)和缺乏良种(14.29%)是制约畜牧生产的主要因素。交易成本高(71.43%)、缺乏资金(35.24%)、缺乏市场信息(23.81%)、价格和需求波动(21.90%)、缺乏市场联动(14.29%)和营销体系无组织(12.38%)是制约畜牧市场经营的主要因素。害虫、投入成本高、土地短缺、杂草丛生、投入短缺、产量低、种子质量差和土壤肥力差被认为是作物生产的重要制约因素。交易成本高、价格产出低、缺乏市场信息和缺乏市场联系是制约作物销售的主要因素。此外,土壤侵蚀、土壤肥力下降、涝渍、土壤酸度和白蚁是自然资源的重要制约因素。需要重视通过改良品种、饲料、控制疾病和控制非法牲畜贸易来提高牲畜生产力。此外,通过病虫害综合治理(IPM)、改良品种、降低交易成本、注重高价值作物、扩大水土保持、加强市场信息和联系等措施提高作物生产力,是迫切需要重点干预的领域。关键词:作物,耕作制度,牲畜,自然资源

Mining and cocoa production are important livelihoods for people in Ghana, particularly in rural communities like Upper Denkyira West District. However, mining activities can have negative impacts on cocoa production and access to basic necessities for the sustenance of the people. This study sought to investigate cocoa farmers’ perception of the impact of mining on socio- economic activities in Upper Denkyira West District and the determinants of their choice of alternative livelihoods. A structured questionnaire was used to collect primary data from 211 respondents who were selected via a multi-stage sampling method for the study. The study found that cocoa farming households agree that mining has negative impacts on socio-economic activities in the district. It was also revealed that about two-thirds of the cocoa farming households were engaged in farm-based and nonfarm-based alternative livelihoods, in addition to cocoa farming. Results from the empirical multinomial logistic regression model showed that sex, years of formal education, farm income, technical skills, extension services, and perception that mining have reduced farm sizes, and farm outputs significantly influence cocoa farming households’ choice of alternative livelihood. The study recommends the need for policies aimed at promoting skills acquisition and facilitating access to markets for products of alternative livelihoods. Key words: Mining, cocoa, alternative livelihoods, multinomial logistic regression, Upper Denkyira West District, Ghana.
采矿和可可生产是加纳人民的重要生计,特别是在上登基拉西区等农村社区。然而,采矿活动可能会对可可生产和人们获得维持生计的基本必需品产生负面影响。本研究旨在调查上登基拉西区可可农民对采矿对社会经济活动影响的看法,以及他们选择替代生计的决定因素。采用多阶段抽样法对211名被调查者进行调查,采用结构化问卷收集原始数据。研究发现,种植可可的农户一致认为,采矿对该地区的社会经济活动有负面影响。调查还显示,除了可可种植外,大约三分之二的可可农户从事农场和非农场的替代生计。实证多项逻辑回归模型的结果显示,性别、受正规教育年限、农场收入、技术技能、推广服务,以及对采矿减少农场规模和农场产出的认知,显著影响可可农户对替代生计的选择。该研究建议,需要制定旨在促进技能获取和便利替代生计产品进入市场的政策。关键词:采矿,可可,替代生计,多项逻辑回归,上登基拉西区,加纳

The periphery of Mbam and Djerem National Park in Cameroon harbors valuable forest resources including key non-timber forest products (NTFPs) that contribute to sustain livelihood of many people in terms of consumption and income generation. However, poor studies have been carried out to assess the socio-economic importance of the value chain of key NTFPs, threats on resources and implication for trade development. We used the value chain analysis approach to map and assess the socio-economic importance of the value chain of three key NTFPs such as Xylopia aethiopica, Beilschmiedia anacardioides and Beilschmiedia jacques-felixii, from forest to market place. The results of the study showed that interesting parts of the plants are the fruits that are harvested and processed for sale or local consumption. Annual profit margins for 17 producers of B. anacardioides and B. jacques-felixiiare was estimated at 1,196,188 FCFA (2023.45 USD) representing 68%, and for 52 producers of X. aethiopica was estimated at 31,280,000 FCFA (52912.57 USD) accounting for 85%. This constitutes an important contribution to the total income of producers of these NTFPs across the region. Profit margins of wholesalers are more important than that of producers and can be classified as follows: 11 wholesaler’s of B. anacardioides and B.  jacques-felixii, 1,908,937 FCFA (3229.12 USD) representing 75% (t-test, df= 26; p= 0.0004); and 20 wholesalers of X. aethiopica, 51,888,000 FCFA (87772.61 USD) representing 94% (t-test, df= 70; p=0.0009). The exploitation of X. aethiopica is practiced by felling the trees and the species recorded a high vulnerable index (VI = 2.61). This practice jeopardizes the natural regeneration of the species in the undergrowth and alters the structure and floristic composition of the plant communities. In the north-eastern part of the park, local people manage the existing species through enrichment plantings. Key words: Values, plant species, products, park, Cameroon.
喀麦隆姆巴姆和杰雷姆国家公园周边蕴藏着宝贵的森林资源,包括关键的非木材森林产品,这些产品有助于维持许多人的消费和创收生计。然而,在评估关键非关税产品价值链的社会经济重要性、对资源的威胁以及对贸易发展的影响方面,进行的研究并不充分。我们使用价值链分析方法绘制和评估了从森林到市场的三个关键NTFP的价值链的社会经济重要性,这些NTFP包括木霉、anacardioides Beilschmiedia和jacques felixii。研究结果表明,这些植物有趣的部分是为出售或当地消费而收获和加工的水果。17家anacardioides和B.jacques felixiire生产商的年利润率估计为1196188 FCFA(2023.45美元),占68%,52家A.ethiopica生产商的年度利润率预计为31280000 FCFA(52912.57美元),约占85%。这对该地区这些非关税产品生产者的总收入构成了重要贡献。批发商的利润率比生产商的利润率更重要,可分为以下几类:11家anacardioides和B.jacques felixii批发商,1908937 FCFA(3229.12美元),占75%(t检验,df=26;p=0.0004);和20个X.aethiopica批发商,51888000 FCFA(87772.61美元),占94%(t检验,df=70;p=0.00009)。通过砍伐树木来开发异食草,该物种记录了高脆弱指数(VI=2.61)。这种做法危及该物种在灌木丛中的自然再生,并改变了植物群落的结构和区系组成。在公园的东北部,当地人通过丰富的种植来管理现有物种。关键词:价值观,植物种类,产品,公园,喀麦隆。

Zimbabwe’s economic progress is hinged on the performance of the agricultural sector, which supports the majority of the population. Bank credit empowers farmers to adopt inputs and technologies that are key for enhancing productivity and income. This study sought to establish the bank credit access trends among farmers in the Hurungwe District of Mashonaland West Province in Zimbabwe, comparing the current (2019-2015) and past (2014-2000) periods. A questionnaire was administered on a sample of 354 farmers. SPSS was used for data analysis. Credit access was significantly (p<0.05) influenced by the type of farmers, farmers’ education, age, farm size and alternative employment. Credit access was higher (p < 0.05) among Model A2 than Model A1 farmers, farmers with higher educational qualifications, aged between 46-55 years, with more than 35 hectares of farmland, and with alternative occupation. Failure to access bank loans by Model A1 farmers was ascribed to their lack of collateral assets, human capital and weather resilience infrastructure. Government should invest in irrigation infrastructure and create a conducive investment climate to stimulate financial capital inflows. Farmers should invest in physical and human capital to enhance their access to bank credit. Banks should devise collateral substitution models to avoid segregating poor farmers with productivity potential. Key words:  Bank credit, capital formation, credit access, Model A1 farmer, Model A2 farmer.
津巴布韦的经济进步取决于农业部门的表现,农业部门为大多数人口提供支持。银行信贷使农民能够采用对提高生产力和收入至关重要的投入物和技术。本研究旨在通过比较当前(2019-2015年)和过去(2014-2000年)时期,确定津巴布韦西部马绍纳兰省胡恩韦地区农民获得银行信贷的趋势。对354名农民进行了问卷调查。采用SPSS软件进行数据分析。农户类型、农户受教育程度、农户年龄、农户规模和替代性就业对信贷获取有显著影响(p<0.05)。A2型农户、学历较高、年龄在46 ~ 55岁之间、耕地面积大于35公顷、从事替代性职业的农户的信贷获得度高于A1型农户(p < 0.05)。A1模式农民无法获得银行贷款的原因是他们缺乏抵押品资产、人力资本和抗灾基础设施。政府应投资灌溉基础设施,创造有利的投资环境,以刺激金融资本流入。农民应投资于物质和人力资本,以增加获得银行信贷的机会。银行应设计抵押品替代模型,以避免将具有生产潜力的贫困农民隔离开来。关键词:银行信贷,资本形成,信贷渠道,A1型农民,A2型农民。

The on-farm diversity of maize cultivars and landraces in the Lacandon region of Chiapas, Mexico 墨西哥恰帕斯州拉坎顿地区玉米品种和地方品种的农场多样性
Pub Date : 2020-07-31 DOI: 10.5897/jdae2020.1170

The loss of maize landraces is of major global concern. Landraces provide the genetic building blocks for the development of high yielding pest- and drought-tolerant maize varieties, and their loss reduces the capacity to adapt to changing environmental conditions. The extinction of maize landraces is an incidental effect of the planting decisions of farmers. Although maize landraces are important both as a staple food and the source of traditional specialty foods required in particular cultural events and ceremonies, they are frequently displaced by high-yielding cultivars. The study considers the factors influencing on-farm maize diversity in the Lacandon tropical forest in the Mexican state of Chiapas. Using a censored regression model fitted with cross-sectional household farmer data, the factors behind crop choices was investigated, paying particular attention to the relation between crop diversity, wealth, and income transfers. It was found that maize diversity bears a non-monotonic relation to wealth, but is positively associated with both agricultural subsidies and poverty support. Key words: Crop choice, crop diversity, Lacandon forest, maize diversity, poverty, on-farm conservation, Mexico, censored regression.
玉米地方品种的丧失是全球关注的主要问题。地方品种为开发高产的抗虫害和抗旱玉米品种提供了遗传基础,它们的丧失降低了适应不断变化的环境条件的能力。玉米地方品种的灭绝是农民种植决定的附带影响。尽管玉米地方品种作为主食和特定文化活动和仪式所需的传统特色食品的来源都很重要,但它们经常被高产品种所取代。该研究考虑了影响墨西哥恰帕斯州拉坎东热带森林农场玉米多样性的因素。本文采用截尾回归模型拟合农户横截面数据,研究了作物选择背后的因素,特别关注作物多样性、财富和收入转移之间的关系。玉米多样性与财富呈非单调关系,但与农业补贴和贫困支持均呈正相关。关键词:作物选择,作物多样性,拉坎东森林,玉米多样性,贫困,农场保护,墨西哥,删节回归。

Strategic networks of agricultural suppliers for the creation of value added are an interesting field of research in the developing countries. Indeed, various scientific works were interested with social networks as well as on their members’ relationship and on their management. However, social networks as strategic suppliers are able to solve SME’s supply credit problems; the need to analyze networks with a view to creating added value for members of these networks remains less examined in literature. To understand the place of the networks in SMEs, a method of content analysis was used to analyze the data collected which included five focus groups of 8 people and twelve interviews. Most participants are producers / suppliers of cassava and shea nuts. The results show that supplier networks allow members to increase their revenues and also improve their skill level. Key words: Supplier networks, added-value, income, welfare.
在发展中国家,创造附加值的农业供应商战略网络是一个有趣的研究领域。事实上,各种科学著作都对社会网络及其成员的关系和管理感兴趣。而社交网络作为战略供应商能够解决中小企业的供应信用问题;为了给这些网络的成员创造附加价值而分析网络的必要性在文献中仍然很少被研究。为了了解网络在中小企业中的地位,采用内容分析的方法对收集的数据进行分析,其中包括5个8人的焦点小组和12个访谈。大多数参与者是木薯和乳木果的生产商/供应商。结果表明,供应商网络使成员增加了收入,也提高了他们的技能水平。关键词:供应商网络,附加值,收益,福利。

This study used Cobb-Douglas Stochastic Profit Frontier to analyze economic efficiency of sorghum farmers in Tharaka Nithi County, Kenya. Using a multi-stage stratified sample of 259 farmers, results depicted a wide range of profit efficiency between the best (0.96) and the worst (0.12) farmer with a mean of 0.17. The actual and potential profit was USD 164.88 ha-1 and USD 969.87 ha-1 respectively. This indicates that, sampled farmers incurred profit-loss of approximately USD 804.99 ha-1. Family labour and fixed capital base were the major contributing factors to sorghum profitability. Drivers of profit efficiency pointed out that, farmers who had more experience in sorghum farming, accessed agricultural credit, attended trainings, lived closer to the market and agro-dealers were likely to be more efficient. To increase profit efficiency, this study therefore advocates for policy strategies targeting these factors. Further, policy move targeting increase in uptake and correct application of fertilizer and other inputs should be reinforced. Key words: Improved sorghum varieties, economic efficiency, Cobb-Douglas stochastic profit frontier, Kenya.
本研究采用Cobb-Douglas随机利润边界法对肯尼亚Tharaka Nithi县高粱农民的经济效率进行了分析。对259名农民进行了多阶段分层抽样,结果显示,最佳(0.96)和最差(0.12)农民之间的利润效率差异很大,平均为0.17。实际利润164.88 ha-1美元,潜在利润969.87 ha-1美元。这表明,抽样农民的损益约为804.99公顷-1美元。家庭劳动力和固定资本基础是高粱盈利的主要因素。利润效率的驱动因素指出,在高粱种植方面有更多经验、获得农业信贷、参加培训、住得离市场和农产品经销商更近的农民可能效率更高。因此,为了提高利润效率,本研究主张针对这些因素制定政策策略。此外,应加强旨在增加肥料和其他投入物的吸收和正确施用的政策措施。关键词:高粱良种,经济效益,科布-道格拉斯随机利润前沿,肯尼亚

Adoption of artificial insemination (AI) in Ethiopia is low and there is paucity of information in documentation. Therefore, the aim of this study is to identify the determinants of smallholder farmers’ adoption of AI technology in Laelay-Maichew district. Multi-stage random sampling technique was employed to select 155 sample respondents for the study. The primary data were collected through individual interviews using semi-structured interview and check list. Descriptive, inferential statistics and binary logistic model were employed to describe the study results and identify the determinants of farmers to adopt improved breeding method of AI. The farmers’ adoption of AI was influenced by access to credit facilities and mobile phone, social participation, formal training, frequency of extension contact, knowledge about AI practice and perception of AI profit positively and  participating in off-farm activities negatively. In conclusion, ownership of information and communication technology (ICT), access to extension services (training and extension visit), knowledge of AI practices and perception of profit determined farmers’ AI adoption. There is a need to improve the effectiveness of extension service through strengthening the training, frequent home visit, making credit service accessible, and educating farmers regarding the knowledge and importance of AI technology for its effective dissemination. Key words: Adoption, artificial insemination (AI), crossbreeding cattle, binary logit econometric model.
埃塞俄比亚人工授精的采用率很低,文件中的信息也很少。因此,本研究的目的是确定Laelay Maichew区小农户采用人工智能技术的决定因素。采用多阶段随机抽样技术,选取155名被调查者进行研究。主要数据是通过使用半结构化访谈和检查表的个人访谈收集的。采用描述性、推断统计学和二元逻辑模型描述研究结果,并确定农民采用改良人工智能育种方法的决定因素,对人工智能实践的了解和对人工智能利润的感知是积极的,对参与场外活动是消极的。总之,信息和通信技术的所有权、获得推广服务(培训和推广访问)、对人工智能实践的了解和对利润的感知决定了农民对人工智能的采用。有必要通过加强培训、经常家访、提供信贷服务以及教育农民人工智能技术的知识和重要性来提高推广服务的有效性。关键词:收养,人工授精,杂交牛,二元logit计量模型。

Despite global efforts to increase food availability and curb high incidence of malnutrition in Africa, there are concerns with regard to high post-harvest losses in Africa. Lesotho like most countries in sub-Saharan Africa faces documented challenges with food insecurity and nutrition. Food availability could be increased by reduction of post-harvest losses without further exploitation of resources. Mitigation of post-harvest losses is seen as a possible antidote for increasing food availability and nutritional status in countries experiencing high food losses. This study investigated the extent of integration of post-harvest management in agricultural policy in Lesotho and strategies to minimise post-harvest losses. Purposive sampling was utilised in order to select a sample of twenty-five respondents on which interviews were conducted. Thematic analysis was used to identify a set of overarching themes that can be used to describe the policy environment and strategies to reduce post-harvest losses. The analysis suggests that there is absence of a direct policy to guide post-harvest management activities in Lesotho, it is only referred to indirectly in other policies with the exception of dairy products sector which has a direct post harvest management policy. Strategies to curb post-harvest losses were also identified. The study concludes that there is need for a direct policy to address post-harvest management in Lesotho. Key words: Lesotho, post harvest management, natural resources, food policy, agricultural development.
尽管全球努力增加粮食供应并遏制非洲营养不良的高发,但非洲收获后损失严重令人关切。像撒哈拉以南非洲的大多数国家一样,莱索托面临着粮食不安全和营养方面的挑战。可以通过减少收获后损失而不进一步开发资源来增加粮食供应。在粮食损失严重的国家,减轻收获后损失被视为增加粮食供应和改善营养状况的可能解决办法。本研究调查了莱索托农业政策中收获后管理的整合程度以及尽量减少收获后损失的战略。有目的的抽样是为了选择25个受访者的样本进行访谈。专题分析用于确定一套可用于描述减少收获后损失的政策环境和战略的总体主题。分析表明,莱索托缺乏指导收获后管理活动的直接政策,除了乳制品部门有直接的收获后管理政策外,其他政策中只间接提到这一点。还确定了遏制收获后损失的战略。该研究的结论是,有必要制定一项直接的政策来解决莱索托的收获后管理问题。关键词:莱索托,收获后管理,自然资源,粮食政策,农业发展

Performance analysis of Nigerian agricultural credit guarantee scheme: Bounds test approach to cointegration 尼日利亚农业信贷担保计划绩效分析:协整的边界检验方法
Pub Date : 2020-05-31 DOI: 10.5897/JDAE2017.0856

This study examined the performance of the Agricultural Credit Guarantee Scheme (ACGS) which is the major credit policy of the Federal Government of Nigeria. It was established in 1977 but started operation in 1978. Time series data from 1978-2014, extracted from the 2014 bulletin of the National Bureau Statistics were used for the study. Total volume and number of loans given were used to proxy the strength of the scheme, while the contribution of agriculture to GDP was used to proxy agricultural productivity. ARDL (Bounds) test approach to cointegration was employed to investigate both long and short run dynamics of ACGS and agricultural growth. The estimated results revealed that there is a long relationship among the total volume of loans, total number of loans and agricultural productivity. The long run elasticity showed that total volume of loan will not significantly influence productivity in the long run while the total numbers of loans have a significant long run relationship with the productivity. In the short run elasticity, total volume of loans was not significant with productivity in the current year while it was significant in the past four years. The total number of loan beneficiaries had a negative but significant relationship with productivity in the past 2 and 3 years while the relationship in the past year was also negative but insignificant. However, there was a positive and significant relationship between total number of loans issued and productivity in the current year. The speed of adjustment, ECT(-1) value of -0.1991 shows that the model will return to long run equilibrium at the speed of 19.91% from short run disequilibrium. Key words: Agricultural credit, Agricultural Credit Guarantee Scheme (ACGS), ARDL, loan volume.
本研究考察了作为尼日利亚联邦政府主要信贷政策的农业信贷担保计划(ACGS)的绩效。它成立于1977年,但于1978年开始运营。该研究使用了从国家统计局2014年公报中提取的1978年至2014年的时间序列数据。提供的贷款总量和数量被用来代表该计划的实力,而农业对GDP的贡献被用来代表农业生产力。采用协整的ARDL(Bounds)检验方法研究了ACGS与农业增长的长期和短期动态。估算结果表明,贷款总量、贷款总量与农业生产率之间存在长期关系。长期弹性表明,从长远来看,贷款总量不会对生产率产生显著影响,而贷款总量与生产率有显著的长期关系。在短期弹性中,贷款总量与当年生产率的关系并不显著,而在过去四年中是显著的。在过去的2年和3年中,贷款受益人的总数与生产力呈负但显著的关系,而在过去的一年中,这种关系也呈负但不显著。然而,本年度发放的贷款总额与生产率之间存在着积极而显著的关系。调整速度,ECT(-1)值-0.1991表明,该模型将以19.91%的速度从短期不平衡回归长期均衡。关键词:农业信贷,农业信贷担保计划,ARDL,贷款量。
