Attempts to ensure safety and quality control in the Day-Old Chicks (DOCs) value chain in Nigeria have been perceived to involve some duplicity/multiplicity of roles and/ or responsibilities, putting undue burden on the actors. Therefore, experts’ workshop on the DOCs value chain in Oyo State was implemented by the Innovation Lab for Policy Leadership in Agriculture and Food Security (PiLAF) to provide a guide for agenda setting for building a better industry. The workshop had the dual purpose of (i) undertaking a situational analysis of the DOCs value chain in Oyo State, Nigeria, and (ii) strengthening the policy process to effectively respond to the needs of the DOCs value chain in the state through clearly defined, unambiguous regulations and regulatory processes. Twenty-four experts comprising major actors along the DOCs value chain in Oyo State participated in the workshop. Using brainstorming and consensus building process, participants identified infrastructure and markets (strengths), weak regulatory control and high operating cost (weaknesses); supply gap, and good return on investment (opportunities); including adulteration and sharp practices (threats) as the most important Strength, Weakness, Opportunities and Threats (SWOT) factors influencing or capable of affecting the DOCs industry in the state. The DOCs value chain operators identified National Institute of Animal Science (NIAS) followed by the Veterinary Council of Nigeria as the most visible operators in the DOCs value chain. However, the operators perceived the activities of the regulatory bodies as more geared toward revenue generation than actually enforcing compliance to standard practices in the industry. The value chain actors affirm there are overlaps in some aspects of policy guidelines for the DOCs value chain by the Veterinary Council of Nigeria and NIAS leading to what may be described as double taxation to the disadvantage of the actors. Specifically, registration and licensing, prohibition, and import and export domains are some of the aspects of the policy documents that need some minor modifications for clarity and separation of roles.

人们认为,尼日利亚为确保日龄雏鸡(DOCs)价值链的安全和质量控制所做的努力涉及到一些重复/多重角色和/或责任,给参与者带来了过重的负担。因此,农业和食品安全政策领导力创新实验室(PiLAF)在奥约州举办了关于雏鸡价值链的专家研讨会,为制定议程以建设更好的产业提供指导。该研讨会具有双重目的:(i) 对尼日利亚奥约州的 DOCs 价值链进行形势分析;(ii) 加强政策进程,通过明确界定、毫不含糊的法规和监管程序,有效应对该州 DOCs 价值链的需求。由奥约州 DOC 价值链主要参与者组成的 24 名专家参加了研讨会。通过集思广益和建立共识的过程,与会者确定了基础设施和市场(优势)、薄弱的监管控制和高昂的运营成本(劣势)、供应缺口和良好的投资回报(机遇),包括掺假和尖锐的做法(威胁),这些都是影响或可能影响该州 DOCs 产业的最重要的优势、劣势、机遇和威胁(SWOT)因素。DOC 价值链经营者认为,国家动物科学研究所(NIAS)和尼日利亚兽医理事会是 DOC 价值链中最引人注目的经营者。不过,经营者认为监管机构的活动更多是为了创收,而不是真正强制行业遵守标准做法。价值链参与者确认,尼日利亚兽医理事会和 NIAS 针对 DOCs 价值链的政策指导方针在某些方面存在重叠,导致双重征税,对参与者不利。具体而言,政策文件中的注册和许可、禁令以及进出口领域等方面需要稍作修改,以明确和区分角色。关键词政策 价值链 动物科学家 雏鸡 安全 家禽业 公共卫生 监管

How households make decisions, who influences decision making and how members bargain over resources and opportunities greatly affects the livelihood and wellbeing of members within a given household. This study sought to understand gender specific decisions and their influence on household technology choice, packaging and adoption of agricultural technologies. Growing Bananas with Trees and Livestock (GBTL) technology system was implemented by National Agricultural Research Organisation and Bioversity International in three districts of Central Uganda: Kiboga, Nakaseke and Ssembabule. Using Principal Component Analysis (PCA) and Cluster Analysis (CA), typologies were created in which two distinct clusters of farming households were revealed. Using a bargaining model of technology adoption, three types of households were identified; male and female only, female only and male only headed households. For technology uptake, either a single component, two components or all components of a technology was adopted. Results indicated that Household size, age, land owned, labour and gender composition of the household positively influenced the adoption of the technology. Farm households were able to take up and adopt components of the technology that were equivalent to the available household resources. Technology choice and adoption was influenced by available land, labor and household objectives (food, income and nutrition security). Households' ability to avert the loss of production and/or assets was very varied and depended on household size. For non-business home expenses, decisions followed a gendered perspective where households with both male and female, had more participants involved in household decision making, households make decision jointly when it comes to purchases and sales. Banana plantations establishment and management was for the spouse. Livestock production was initiated and managed by the household heads. Individual decisions were influenced by age of the household head, livestock owner. Joint household’s decision making was significant on purchases, sales of inputs and outputs, land ownership, and were influenced by household size and farm size. This study brings out important policy implications that in order to ensure widespread adoption of improved technologies, there should be equitable access to complementary inputs, especially land and labour for females. And technology packaging should take into consideration the gender specific decisions for sustainable agricultural development. Key words: Decision making, Technology choice, adoption, Coffee banana farming system, Gender
家庭如何做出决策、谁对决策产生影响以及家庭成员如何就资源和机会进行讨价还价,在很大程度上影响着特定家庭中成员的生计和福祉。本研究试图了解性别决策及其对家庭技术选择、包装和农业技术采用的影响。国家农业研究组织和国际生物多样性组织在乌干达中部的三个地区实施了 "用树木和牲畜种植香蕉(GBTL)"技术系统:基博加、纳卡塞克和森巴布勒。利用主成分分析法(PCA)和聚类分析法(CA)创建了类型,其中揭示了两个不同的农户聚类。利用技术采用的讨价还价模式,确定了三种类型的家庭:男女户主家庭、女性户主家庭和男性户主家庭。在技术吸收方面,采用了技术的单一组成部分、两个组成部分或所有组成部分。结果表明,家庭规模、年龄、拥有的土地、劳动力和家庭性别构成对技术的采用有积极影响。农户能够接受和采用与现有家庭资源相当的技术部分。技术选择和采用受可用土地、劳动力和家庭目标(粮食、收入和营养安全)的影响。家庭避免生产和/或资产损失的能力各不相同,取决于家庭规模。在家庭非经营性支出方面,决策遵循性别观点,即有男性和女性的家庭有更多人参与家庭决策,在涉及购买和销售时,家庭共同做出决定。香蕉种植园的建立和管理由配偶负责。家畜生产由户主发起和管理。个人决策受户主和牲畜所有者年龄的影响。共同家庭在购买、销售投入和产出、土地所有权方面的决策意义重大,并受到家庭规模和农场规模的影响。这项研究提出了重要的政策含义,即为了确保改良技术的广泛采用,应公平获得补充投入,尤其是女性的土地和劳动力。技术包装应考虑到性别差异对农业可持续发展的影响。关键词决策、技术选择、采用、咖啡香蕉种植系统、性别

Of recent, there is changing work environment for agricultural extension workers as they operate under the multi-stakeholders’ phenomenon. This increasingly poses a challenge to frontline extension workers trained on linear model (extension-researcher-farmer linkage) in extension services delivery. This is because, facilitating the multi-stakeholder processes requires competent agricultural extension workers well-versed in human relations. In recognizing the importance of human capital development for agricultural extension service delivery in Tanzania, Sokoine University of Agriculture established a mid-career agricultural extension training programme in 1998. Informed by the human capital theory, this study employed an evaluative study design to assess the impact of the Sokoine University of Agriculture (SUA) mid-career BSc. Agricultural Extension and Education training programme on human capital development. The study was conducted in five agro-ecological zones, that is, Eastern, Western, Central, Southern Highlands and Lake zones in Tanzania. The development of the sampling frame was done in collaboration with the Ministry of Agriculture (MoA), Ministry of Livestock and Fisheries (MLF) and President’s Office-Regional Administration and Local Government (PO-RALG). A total of 200 respondents-100 alumni and 100 farmers were sampled proportionately. A snowball sampling technique was used to replace the respondents who were selected randomly but could not be reached for interview. Data were collected from respondents through a questionnaire that covered a set of competences through analysis of the mid-career agricultural extension curriculum and consultations with public and private employers. In addition, literature review and observations were also used to supplement the collected information. The findings indicate that the agricultural training programme at Sokoine University of Agriculture (SUA) equipped graduates with appropriate knowledge, competencies and skills that improved their job performance and productive capacities that enabled them to interact with various stakeholders and facilitate multi-stakeholders’ processes. This is in line with the purpose of establishing the programme. Hence, this points to the need for continuous human capital building and motivations of agricultural extension workers for the improvement of their performance.

最近,农业推广人员的工作环境发生了变化,因为他们是在多方利益相关者的现象下开展工作的。这对接受过线性模式(推广-研究人员-农民联系)推广服务培训的一线推广人员日益构成挑战。这是因为,促进多方利益相关者进程需要精通人际关系的称职农业推广人员。坦桑尼亚索科因农业大学认识到人力资本开发对提供农业推广服务的重要性,于 1998 年设立了职业生涯中期农业推广培训计划。在人力资本理论的指导下,本研究采用了评估性研究设计,以评估索科因农业大学(Suoine University of Agriculture,SUA)职业生涯中期农业推广和教育理学士培训计划的影响。农业推广和教育培训计划对人力资本开发的影响。这项研究在坦桑尼亚的五个农业生态区进行,即东部、西部、中部、南部高地和湖区。抽样框架是与农业部(MoA)、畜牧和渔业部(MLF)以及地区行政和地方政府总统办公室(PO-RALG)合作制定的。共按比例抽取了 200 名受访者--100 名校友和 100 名农民。对于随机抽取但无法联系到的受访者,采用了 "滚雪球 "抽样技术进行替换。通过对职业生涯中期农业推广课程的分析以及与公共和私营雇主的磋商,以调查问卷的形式向受访者收集数据,调查问卷涵盖了一系列能力。此外,还利用文献回顾和观察来补充收集到的信息。研究结果表明,索科因农业大学(Sokoine University of Agriculture,SUA)的农业培训课程为毕业生提供了适当的知识、能力和技能,提高了他们的工作绩效和生产能力,使他们能够与各利益相关方互动,促进多方利益相关方的进程。这与设立该计划的目的是一致的。因此,这说明有必要持续进行人力资本建设,激励农业推广人员提高工作绩效。关键词职业生涯中期 农业推广人员 课程 人力资本 多方利益相关者进程

Agricultural extension debatable issues 农业推广值得商榷的问题
Q3 Social Sciences Pub Date : 2024-04-06 DOI: 10.18697/ajfand.128.24275
J. Mutimba
Extension, and extension workers in particular, drive the agricultural modernization process and the rest of those in associated professions and positions are ‘support staff.’ Whether you are a lecturer, a professor, a dean, a researcher, an extension director or a head of a non-government organization, if your mission is to develop smallholder agriculture at farmer level, you are supporting the field extension worker to achieve your/farmers’ goals. To this extent, it is no surprise that, when no perceptible improvement takes place at the farmer level, the blame lies squarely on the shoulders of extension. Despite its importance, agricultural extension is the most misunderstood of all agricultural disciplines, and the lack of understanding reveals itself in several ways. This paper discusses some of the misconceptions and debatable issues that affect the way extension is supported, the way it is structured, the way it is staffed and the way extension workers are trained and capacitated. The misconceptions also affect the kinds and levels of expectations people have of extension. The misconceptions include: unending definitions of extension, expanding extension concepts, blaming extension for perceived failures in agriculture, undermining the extension discipline, inadequacies in extension teaching and training, markets and the role of extension and structural changes in extension. The origins of some of these debatable issues can be traced to development partners who come with their conceptions of what is needed while others come from development theorists who have not done any extension work in the field. Unfortunately, there are no strong extension professional associations in many African countries that could: raise the profile of extension as a discipline, interrogate some of the agricultural development interventions before implementation and help clear some of the misconceptions. In the absence of extension platforms, extensionists operate as individuals, each struggling the best way they know how to make a difference at the farmer level. There is no way of harnessing the experiences the individuals are going through for purposes of learning, sharing and developing common positions. The purpose of this paper is to promote debate on, and scrutiny of these extension issues which are often presented as facts and absolute truths. Key words: Extension issues, debatable, agricultural discipline, misconceptions, professionals, smallholder farmers
推广工作,尤其是推广人员,推动着农业现代化进程,而其他相关职业和职位的人员则是 "辅助人员"。无论你是讲师、教授、院长、研究员、推广主任还是非政府组织的负责人,如果你的任务是在农民层面发展小农农业,那么你就是在支持实地推广人员实现你/农民的目标。因此,当农民没有得到明显改善时,将责任完全归咎于推广人员也就不足为奇了。尽管农业技术推广十分重要,但它却是所有农业学科中最容易被误解的学科,而这种误解表现在多个方面。本文讨论了一些误解和值得商榷的问题,这些问题影响了对推广工作的支持方式、结构方式、人员配备方式以及对推广人员的培训和能力提升方式。这些误解也影响了人们对推广工作的期望种类和期望水平。这些误解包括:对推广工作的无休止的定义、推广概念的扩展、将农业的失败归咎于推广工作、破坏推广纪律、推广教学和培训的不足、市场和推广工作的作用以及推广工作的结构性变化。其中一些有争议的问题可以追溯到发展合作伙伴,他们提出了自己的需求理念,而另一些问题则来自没有在实地开展过任何推广工作的发展理论家。遗憾的是,许多非洲国家没有强有力的推广专业协会,而这些协会可以:提高推广作为一门学科的地位,在实施之前对一些农业发展干预措施进行审查,并帮助澄清一些误解。在缺乏推广平台的情况下,推广人员各自为战,以他们所知道的最佳方式在农民层面发挥作用。没有办法将个人的经验用于学习、分享和发展共同立场。本文旨在促进对这些推广问题的讨论和审查,这些问题往往被当作事实和绝对真理。关键词推广问题、辩论、农业学科、误解、专业人员、小农户

Against the background of low women’s participation in farm decision making processes, Malawi’s agriculture sector adapted and up- scaled Household Approach, a gender transformative tool known for its impact in enhancing participation of women in farm decision making processes. In this study, participation in farm decision making is defined as the involvement of women, men and youth in decision making process in relation to visioning, planning, implementation, monitoring and evaluation. The objective of this study was to determine level of participation of women under Household Approach in farm decision making processes. This was a cross- sectional study. Using a semi-structured interview, a quantification of the extent of participation of various gender categories in decision making in various areas was determined. Thirty- three households were purposively selected due to their participation in Household Approach. Analysis of women participation in decision making, was done by computing women’s decision score. Decision score for men and youth was also computed so that a comparison is made to women’s level of participation. Women took joint decisions in all farm decision making processes with a higher participation score in household visioning (0.91) compared to men (0.83) and youth (0.44). When it came to implementing production activities of an enterprise (maize) which is a major source of their livelihood determining fulfilment of their visions, there were significant variations among their participation score in decision making in relation to maize enterprise production (χ2 (2) = 40.282, p = 0.000) with a mean rank participation score of 25.00, 39.94 and 8.56 in men, women and youth, respectively. This implies that much as implementation of maize production activities are jointly done with men, women still do a greater part of maize production work. When it came to monitoring, women had a lower participation score (0.68) compared to men (0.81), but higher than the youth (0.33). The lower participation score in monitoring among women was due to multiple roles the women have. This study recommends that sharing of roles be encouraged among peer households. Key words: Level, Women, participation, Household Approach, Farm, Decision making, Pragmatic, Cross- sectional
在妇女很少参与农场决策过程的背景下,马拉维农业部门调整并推广了 "家庭方法",这是一种 以提高妇女参与农场决策过程的影响力而闻名的性别变革工具。在本研究中,参与农场决策被定义为妇女、男子和青年参与与愿景、规划、实施、监测和评估有关的决策过程。本研究的目的是确定家庭法下妇女参与农场决策过程的程度。这是一项横断面研究。通过半结构式访谈,确定了不同性别类别参与各领域决策的量化程度。由于参与了 "家庭方法",研究人员有目的地选择了 33 个家庭。通过计算妇女的决策得分,对妇女参与决策的情况进行了分析。同时还计算了男性和青年的决策得分,以便与妇女的参与程度进行比较。在所有农场决策过程中,妇女都是共同决策人,在家庭远景规划中的参与度得分(0.91)高于男性(0.83)和青年(0.44)。企业(玉米)是他们生计的主要来源,也是他们实现愿景的决定性因素。在实施企业(玉米)生产活动时,他们在玉米企业生产决策方面的参与得分存在显著差异(χ2 (2) = 40.282, p = 0.000),男性、女性和青年的平均参与得分分别为 25.00、39.94 和 8.56。这意味着,尽管玉米生产活动的实施是与男性共同完成的,但女性仍然承担了更多的玉米生产工作。在监测方面,妇女的参与度得分(0.68)低于男子(0.81),但高于青年(0.33)。妇女在监督方面的参与度较低是由于她们身兼数职。本研究建议鼓励同辈家庭分担角色。关键词水平、妇女、参与、家庭方法、农场、决策、务实、横断面

When it came to monitoring, women had a lower participation score (0.68) compared to men (0.81), but higher than the youth (0.33). The lower participation score in monitoring among women was due to multiple roles the women have. This study recommends that sharing of roles be encouraged among peer households.

This survey aimed to establish nutrition-related knowledge, attitudes and practices, and to observe how gender influences household food-related decision-making processes in the Sasakawa Africa Association (SAA) intervention areas in the Oromia and Southern Nation Nationalities and People regions of Ethiopia. The findings would inform implementation of communication for nutrition social and behaviour change among small-holder farmers as part of the SAA corporate strategy on nutrition-sensitive agriculture. The study population was smallholder farmers supported by SAA from which 311 respondents were selected through multistage sampling. Data were collected via a mixed methods approach consisting of a household survey, focus group discussions (FGDs) and key informant interviews (KIIs). Quantitative data were analysed using descriptive statistics while qualitative data was analysed using a narrative and content approach. The study focused on knowledge, attitudes and practices related to production and consumption of micronutrient-rich foods. Majority (59.5%) of the respondents were male. Men were the main decision makers on staple or commercial food crop production and proportion of produced crops to be consumed at home or sold in the market. Women mainly made decisions regarding production and consumption of fruits and vegetables, intra-household food distribution, preservation and storage. There was a lack of knowledge on iron and vitamin A fortified or biofortified sources of food. Nearly three quarters (72%) of women did not meet the minimum dietary diversity for women, a proxy indicator of adequacy of micronutrient intake and diet quality. The mean dietary diversity score was 3.8 with animal source foods being the least consumed. Not having sufficient money to buy food, unavailability of different food groups and poor intra-household food distribution were among the key reasons for lack of diverse diets. Majority of the respondents were aware of the importance of production and consumption of micronutrient-rich foods. However, there was a gap in practice and awareness about biofortified and fortified foods. While most of the respondents had produced fruits and vegetables in home gardens in the three months prior to this survey, more than half (54%) of the respondents thought it was not likely that they would produce fruits and vegetables for home consumption. More targeted nutrition campaigns are required to increase the ability of small-holder farmers to adopt best practices while reducing the barriers associated with access and consumption. Promotion of fruit and vegetable production in home gardens could be considered as option for improving household dietary quality as well as empowering women to make more decisions.

这项调查旨在确定与营养有关的知识、态度和做法,并观察性别如何影响埃塞俄比亚奥罗莫地区和南方民族和人民地区笹川非洲协会(SAA)干预地区与食品有关的家庭决策过程。作为笹川非洲协会营养敏感型农业企业战略的一部分,研究结果将为在小农户中开展营养社会和行为改变交流活动提供参考。研究对象是 SAA 支持的小农户,通过多阶段抽样从中选出了 311 名受访者。数据收集采用混合方法,包括家庭调查、焦点小组讨论 (FGD) 和关键信息提供者访谈 (KII)。定量数据采用描述性统计方法进行分析,定性数据则采用叙述和内容方法进行分析。研究的重点是与富含微量营养素食品的生产和消费有关的知识、态度和做法。大多数受访者(59.5%)为男性。男性是主食或商业粮食作物生产的主要决策者,也是家庭消费或市场销售比例的主要决策者。妇女主要决定水果和蔬菜的生产和消费、家庭内部食物分配、保存和储存。妇女对铁和维生素 A 强化或生物强化食品的来源缺乏了解。近四分之三(72%)的妇女达不到妇女最低膳食多样性标准,而这是衡量微量营养素摄入量和膳食质量是否充足的替代指标。膳食多样性的平均得分为 3.8 分,其中动物源性食物的摄入量最少。没有足够的钱购买食物、无法获得不同种类的食物以及家庭内部食物分配不均是造成膳食缺乏 多样性的主要原因。大多数受访者都知道生产和消费富含微量营养素的食物的重要性。然而,在实践和对生物强化和强化食品的认识方面还存在差距。虽然大多数受访者在调查前三个月曾在家庭菜园中生产过水果和蔬菜,但超过一半(54%)的受访者认为他们不太可能生产水果和蔬菜供家庭食用。需要开展更有针对性的营养宣传活动,以提高小农户采用最佳做法的能力,同时减少与获取和消费相关的障碍。在家庭菜园中推广水果和蔬菜生产可被视为提高家庭膳食质量以及赋予妇女更多决策权的一种选择。关键词笹川非洲协会 小农户 营养 知识 实践

Gari is the most popular form in which cassava is consumed in most households in Nigeria. However, gari is deficient in most food nutrients and its excessive consumption without supplementation leads to malnutrition. Soygari (Gari fortified with soyabean) could help reduce malnutrition if positive behaviour is elicited through appropriate Communication Media (CM). However, empirical evidence on suitable CM mix to elicit positive behaviour towards Soygari nutrition is scarce. Therefore, CM mix for behavioural change in Soygari nutrition information dissemination among rural households in southwestern Nigeria was investigated. This study evaluated the effect of consistent dosage of Soygari information on rural women’s behaviour in South Western Nigeria. A quasi-experimental research design was used. Data were collected from 224 women in soybean-producing households in the region through a systematic sampling procedure. This study trained women in Soygari information for twelve weeks using podcasts (audio and video messages), and interactive (demonstrations and visual teaching methods). The study targeted change in women’s knowledge, attitude, and utilization. Empirical analyses are described in tables and percentages, while parametric tests were used to analyze a priori hypotheses. The podcast method influenced higher change in Knowledge (Δx ̅ = 2.68) and attitude (Δx ̅=5.94) of women while a higher change in utilization (Δx ̅= 7.32) was found among women exposed to the interactive method. A significant difference existed in the utilization (T = 4.018; p < 0.05) of Soygari among women exposed to the podcast and interactive methods. Both media types effectively promoted positive behavioural change towards Soygari nutrition among rural households in South western Nigeria. Audio and practical demonstration mix were most suitable. An interactive method of communication is best if the target of nutrition information is for immediate household utilization. Multiple dosages of information can be a motivation to change an already existing human behaviour even when distractions exist. Key words: Change in behaviour, Soygari, Nutrition-Specific diet, media use, Women
Gari 是尼日利亚大多数家庭食用木薯的最普遍形式。然而,Gari 缺乏大多数食物营养素,过量食用而不补充营养素会导致营养不良。如果通过适当的传播媒介(CM)激发积极的行为,大豆加里(强化大豆的加里)将有助于减少营养不良。然而,有关通过适当的传播媒介组合激发人们对 Soygari 营养的积极行为的经验证据却很少。因此,本研究调查了在尼日利亚西南部农村家庭中传播 Soygari 营养信息时改变行为的传播媒介组合。本研究评估了一致剂量的 Soygari 信息对尼日利亚西南部农村妇女行为的影响。研究采用了准实验研究设计。通过系统抽样程序从该地区 224 个生产大豆的家庭中收集了数据。这项研究利用播客(音频和视频信息)和互动(示范和直观教学方法)对妇女进行了为期 12 周的 Soygari 信息培训。研究的目标是改变妇女的知识、态度和使用情况。实证分析以表格和百分比的形式进行描述,而参数检验则用于分析先验假设。播客方法对妇女知识(Δx ̅=2.68)和态度(Δx ̅=5.94)的变化影响较大,而互动方法对妇女利用(Δx ̅=7.32)的变化影响较大。在使用播客和互动方法的妇女中,Soygari 的使用率存在明显差异(T = 4.018;p < 0.05)。两种媒体类型都有效地促进了尼日利亚西南部农村家庭对 Soygari 营养的积极行为改变。音频和实际示范的组合最合适。如果营养信息的目标是供家庭立即使用,那么互动式传播方法是最好的。即使存在干扰因素,多种剂量的信息也能促使人们改变已有的行为。关键词行为改变、大豆食品、特定营养膳食、媒体使用、妇女

Review on novel approaches for controlling aflatoxin B1: Harnessing nature's defenses against food toxins 控制黄曲霉毒素 B1 的新方法综述:利用大自然的防御系统抵御食物毒素

Aflatoxin B1 is the most harmful food toxin for humans and animals. According to the International Agency for Research on Cancer, it is ranked as one of the most carcinogenic substances in the world, directly connected to hepatocarcinoma in both humans and animals. Aflatoxin B1 is also involved in the occurrence of pathologies, and aflatoxicoses. Aflatoxin B1 can be produced by fungi from the genus Aspergillus section Flavi in a variety of foods during storage. Once aflatoxins are present, food processing cannot eradicate them. The damage and lack of complete elimination of aflatoxins from foodstuffs make them the most monitored and controlled substances in the world. Given the high-risk of Aflatoxin B1 on both animal and human health, it is important to study their worldwide distribution and existing control methods through a systematic review. Articles published from 1945 to 2022 found on several databases as Scopus, PubMed, Dimensions, Google Scholar and an extraction sieve was used to select the relevant articles. Of the two hundred and twenty-eight (228) French and English scientific articles on aflatoxins identified, forty of the most relevant original articles were selected for inclusion in this review following a rigorous selection process. Several genes are involved in the synthesis of aflatoxin B1. Moreover, certain environmental conditions, in particular oxidative stress are propitious for fungus by over-expressing aflatoxins. However, the fungi defences can be controlled by several methods. Articles showed efficiency of various of them. Good cultural practices and awareness raising are part of the preventive control. Synthetic chemicals such as insecticides and fungicides are chronically used in chemical control of fungal growth and prevent aflatoxins from being produced. Biological control is based on allelic recombination between toxic and atoxic strains. The use of microbial competition is focused on the natural predators of aflatoxic molds, most often lactic acid bacteria, and the natural control relies on the use of natural plant substances. Natural substances like aqueous or organic plant extracts that contain proteins, polyphenols, tannins, antioxidants, flavonoids, terpenes, and chelating ion as well as caffeic acid, gallic acid and ascorbic acid can be used to control fungal contamination currently. These molecules interfere with free radicals to slow down or even inhibit the production of reactive oxygen species significantly reducing the production of aflatoxins making them inactive. Implementation of the means of controlling fungal growth and producing aflatoxins will help make agriculture globally competitive and ensure food security. Key words: Natural substances, Aflatoxin B1, food poisoning, alternative control, biocontrol
黄曲霉毒素 B1 是对人类和动物危害最大的食物毒素。根据国际癌症研究机构的研究,它被列为世界上最容易致癌的物质之一,与人类和动物的肝癌直接相关。黄曲霉毒素 B1 还会导致病变和黄曲霉毒素中毒。黄曲霉毒素 B1 可由各种食品中的黄曲霉属真菌在储存过程中产生。一旦出现黄曲霉毒素,食品加工过程就无法将其消除。黄曲霉毒素对食品造成的损害和无法彻底消除,使其成为世界上最受监测和控制的物质。鉴于黄曲霉毒素 B1 对动物和人类健康的高风险,通过系统回顾研究其在全球的分布情况和现有的控制方法非常重要。从 Scopus、PubMed、Dimensions、Google Scholar 等多个数据库中查找了 1945 年至 2022 年间发表的文章,并使用提取筛筛选出相关文章。在确定的 228 篇有关黄曲霉毒素的法文和英文科学文章中,经过严格的筛选过程,选出了 40 篇最相关的原创文章纳入本综述。黄曲霉毒素 B1 的合成涉及多个基因。此外,某些环境条件,特别是氧化压力,有利于真菌过度表达黄曲霉毒素。不过,真菌的防御能力可以通过几种方法来控制。一些文章展示了各种方法的有效性。良好的文化习俗和提高认识是预防控制的一部分。杀虫剂和杀真菌剂等合成化学品长期用于真菌生长的化学防治,可防止黄曲霉毒素的产生。生物防治的基础是有毒和无毒菌株之间的等位基因重组。微生物竞争的使用主要是针对黄曲霉的天敌,最常见的是乳酸菌,而自然控制则依赖于天然植物物质的使用。含有蛋白质、多酚、单宁、抗氧化剂、类黄酮、萜烯、螯合离子以及咖啡酸、没食子酸和抗坏血酸的水性或有机植物提取物等天然物质目前可用于控制真菌污染。这些分子能干扰自由基,减缓甚至抑制活性氧的产生,从而大大减少黄曲霉毒素的产生,使其失去活性。采用控制真菌生长和黄曲霉毒素产生的方法将有助于提高农业的全球竞争力,确保粮食安全。关键词天然物质 黄曲霉毒素 B1 食物中毒 替代控制 生物控制

Let us talk about Agricultural Extension 让我们谈谈农业推广
Q3 Social Sciences Pub Date : 2024-04-06 DOI: 10.18697/ajfand.128.ed137
Ruth Oniang'o
I have always been interested in agricultural extension from the time I used to see extension workers visit my mum, then a peasant farmer in the village, working hard to make sure her family was always food secure. Even though her husband (my father) was out on a government job, she understood that she had to do her bit. His salary would be reserved for paying school fees for the children, putting up good housing, and providing some material goods that could put them at a certain level in society. Cash was highly valued, as it still is today. My mother was not farming to sell. Whatever excess she had would be shared with needy relatives and neighbors. With the support of extension workers who used to provide free seeds, teach how to make compost manure, and then guide farmers all the way to harvest and storage, we never lacked food except when there was a very serious famine. I remember feeling hunger pangs, at a time when we had porridge only for breakfast, no lunch, and then had a full meal at dinner. The memory of those hunger pangs is the reason why I am not happy when I hear of children going hungry for whatever reason.
我一直对农业技术推广很感兴趣,因为我经常看到技术推广人员去看望我的母亲,她当时是村里的一个农民,正在努力工作,以确保她的家人始终有饭吃。尽管她的丈夫(我的父亲)在外从事政府工作,但她明白自己必须尽一份力。他的工资将留作支付孩子们的学费、建造好的住房,以及提供一些能让他们在社会上处于一定地位的物质财富。现金很值钱,今天依然如此。我的母亲不务农,也不卖钱。无论她有多少余粮,都会分给有需要的亲戚和邻居。在推广人员的支持下,他们经常免费提供种子,教授如何制作堆肥,然后指导农民收割和储存,除了发生严重饥荒时,我们从未缺过粮食。我还记得,那时候我们的早餐只有稀饭,没有午餐,晚餐才吃一顿饱饭。回忆起那段饥肠辘辘的日子,每当我听到孩子们因任何原因挨饿时,我都会感到不快。

Agriculture in Africa is undergoing transformative shifts, driven by the need for sustainable food production, increased productivity, and resilience to challenges such as climate change. This paper explores the current state of agriculture extension models in Africa and their role in delivering technologies and innovations to target beneficiaries and other stakeholders in agricultural innovation systems. We delve into key challenges, promising approaches, and recommendations for enhancing the effectiveness of extension services in the dynamic agricultural landscapes of Africa. The paper showcases innovative extension models by Sasakawa Africa Association that have made a significant impact. These include Farmer Learning Platforms (FLPs) model, Private and Extension Service Provision (PESP), The Agro-Processing Enterprise Center (APEC) Model, Community-Based Seed Multiplication (CBSM) model, private and extension service provision Model (PESP), and the community savings for investment in Agribusiness (CSIA) model. The Sasakawa Africa Fund for Education (SAFE) Demand Driven Curriculum (SDDC) model is also highlighted. These examples highlight the importance of context-specific approaches and the role of extension in empowering farmers to embrace sustainable and resilient agricultural practices.

This paper explores the current state of agriculture extension models in Africa and their role in delivering technologies and innovations to target beneficiaries and other stakeholders in agricultural innovation systems. We delve into key challenges, promising approaches, and recommendations for enhancing the effectiveness of extension services in the dynamic agricultural landscapes of Africa. The paper showcases innovative extension models by Sasakawa Africa Association that have made a significant impact. These include Farmer Learning Platforms (FLPs) model, Private and Extension Service Provision (PESP), The Agro-Processing Enterprise Center (APEC) Model, Community-Based Seed Multiplication (CBSM) model, private and extension service provision Model (PESP), and the community savings for investment in Agribusiness (CSIA) model. The Sasakawa Africa Fund for Education (SAFE) Demand Driven Curriculum (SDDC) model is also highlighted. These examples highlight the importance of context-specific approaches and the role of extension in empowering farmers to embrace sustainable and resilient agricultural practices.
