This study provides empirical estimation results concerning the degree of production coupling for the fixed and variable direct payment program designed for stabilizing rice farmers’ income. Based on a set of producer’s expectation formulations, we analyzed the impacts of direct payments on the rice cultivation area, using a panel data estimation technique. To consider the risk preference of farmers, we used an expected utility maximization model under the expected utility hypothesis. Also, we explicitly included a variable capturing truncated variance of rice price related to variable direct payments. Our estimation results indicate that both fixed and variable direct payments tend to have production coupling effects. Specifically, we found that the production coupling effect of variable direct payments was higher than that of fixed direct payments. We also discovered that the rice cultivation area has been affected by these direct payments via the insurance effects (variable direct payments) and wealth effects (fixed direct payments). 차례 1. 서론 2. 선행연구 검토 3. 분석모형 및 자료 4. 분석 결과 5. 요약 및 결론 * 이 연구는 한국농촌경제연구원의 수탁연구 내용 일부를 논문화한 것이며 논문작성에 도움을 주신 김종진 박사님께 감사의 말씀 을 드립니다. ** 경남연구원 연구위원 *** 서울대학교 농경제사회학부 교수, 교신저자. e-mail: kimk@snu.ac.kr
本研究提供了稳定稻农收入的固定和可变直接支付方案的生产耦合程度的实证估计结果。基于一套生产者期望公式,采用面板数据估计技术,分析了直接补贴对水稻种植面积的影响。为了考虑农民的风险偏好,我们采用了期望效用假设下的期望效用最大化模型。此外,我们明确地包括了一个变量,捕获了与可变直接支付相关的大米价格的截断方差。我们的估计结果表明,固定和可变直接支付都倾向于产生生产耦合效应。具体而言,我们发现可变直接支付的生产耦合效应高于固定直接支付。我们还发现,水稻种植面积通过保险效应(可变直接支付)和财富效应(固定直接支付)受到这些直接支付的影响。1.使用实例2。【翻译】[au:][au:]요약및결론*이연구는한국농촌경제연구원의수탁연구내용일부를논문화한것이며논문작성에도움을주신김종진박사님께감사의말씀을드립니다。*** *** *** *** *** *** *** *** *电子邮件:kimk@snu.ac.kr

Integrated Pest Management techniques (IPM) have been promoted last decade throughout a large Urban and Periurban Horticulture project (UPH) for a sustainable vegetable production in Congolese cities. However, the drivers of adoption of IPM techniques have not been either studied or identified. Data collected between April and June 2016 throughout field survey from 246 vegetable farmers were analyzed using a logistic regression model to determine the factors influencing the adoption of IPM techniques among vegetable farmers. Results showed that there were no significant differences between gender and the willingness to use IPM (p>0.05). However, a high portion of female (46.6%) reported that they would like to test new IPM techniques without any hesitation. Membership to a farmer’s group (Association) and previous agricultural training influenced positively and significantly the IPM adoption (p= 0.000) and increased highly the probability of adopting IPM respectively 4.2 and 7.7 times. Further, results also highlighted that farmers who previously perceived negative effects of pesticides were likely 5.2 times predisposed (p<0.05) to adopt alternative methods of pest control. Findings will allow an increased understanding of the process of IPM adoption and will help provide policy guidance to promote IPM diffusion with a purpose of reducing pesticide issues among farmers.
在过去十年中,在一个大型城市和城郊园艺项目(UPH)中推广了害虫综合治理技术,以促进刚果城市的可持续蔬菜生产。然而,采用IPM技术的驱动因素尚未得到研究或确定。采用logistic回归模型对2016年4月至6月对246名菜农进行实地调查收集的数据进行分析,确定影响菜农采用IPM技术的因素。结果显示,性别与IPM使用意愿无显著差异(p < 0.05)。然而,很大一部分女性(46.6%)报告说,她们愿意毫不犹豫地测试新的IPM技术。农民团体(协会)成员资格和以前的农业培训对采用IPM有显著的正向影响(p= 0.000),并使采用IPM的概率分别提高4.2倍和7.7倍。此外,研究结果还强调,以前认为农药有负面影响的农民可能更倾向于采用其他虫害防治方法(p<0.05)。研究结果将有助于进一步了解采用IPM的过程,并将有助于提供政策指导,促进IPM的推广,以减少农民中的农药问题。

Adaptation to Climate Change among Farmers in Bulacan, Philippines 菲律宾布拉干农民对气候变化的适应

The vulnerability of the Philippines to climate change and variability has been highlighted by its exposure to severe weather-related conditions. Farmers are particularly vulnerable to such adverse effects given their limited adaptive capacity. In this regard, this study examines the local adaptation experiences and practices of farmers in a second-class farming municipality. It is then based on the assumption that a lay understanding of how farmers perceive and adapt to climate change can be used to provide implications for enhancing their adaptive capacity. Using a combination of qualitative data from key informant interviews and focus group discussion and secondary data from government agencies, this paper reveals that farmers perceive serious health and livelihood risks despite having limited knowledge of how climate change occurs. They recognize that changes in climate conditions have caused considerable effects to temperature and rainfall which, in turn, have posed serious challenge to water supply. Their farming activities are also at risk from interrelated impacts such as damage to crops, pest infestation, and decrease in rice yield. Hence, they consistently employ common adaptation measures as direct responses to climate variability such as the planting of new crop varieties, use of chemical fertilizers and pesticides, use of technology in farming, and diversification of household income. However, the lack of financial resources hinders them from utilizing new adaptation techniques and technologies, which they perceive to be more appropriate and beneficial. These results suggest a more conscious effort of transforming coping strategies to short-term climate variability into adaptation measures to long-term climate changes.

菲律宾易受气候变化和多变性的影响,其暴露于与恶劣天气有关的条件下。由于农民的适应能力有限,他们特别容易受到这种不利影响。在这方面,本研究考察了一个二级农业直辖市农民的地方适应经验和做法。然后,它基于这样的假设:对农民如何感知和适应气候变化的外行理解可以用来为提高他们的适应能力提供启示。本文结合了来自关键信息者访谈和焦点小组讨论的定性数据以及来自政府机构的二手数据,揭示了农民尽管对气候变化如何发生的了解有限,但仍感知到严重的健康和生计风险。他们认识到气候条件的变化对温度和降雨造成相当大的影响,进而对供水构成严重挑战。他们的农业活动也受到相关影响的威胁,如作物受损、虫害和水稻减产。因此,他们一贯采用共同的适应措施,如种植新作物品种、使用化肥和农药、在农业中使用技术以及家庭收入多样化等,作为对气候变化的直接反应。然而,缺乏财政资源阻碍了他们利用新的适应技术和技术,他们认为这些技术和技术更适当和有益。这些结果表明,需要更加有意识地将应对短期气候变率的策略转变为适应长期气候变化的措施。关键词:气候变化;适应;农民;农业;菲律宾---------------------------------------------------------适应气候变化与气候变化的关系与气候变化的关系与气候变化的关系与气候变化的关系与气候变化的关系与气候变化的关系与极端气象条件的关系。农民特别容易受到不利影响,完全没有适应能力的限制。另一方面,我们的研究人员研究了“适应农业的经验”和“地方农业的经验”,以及“城市农业的经验”。将“套间”定义为“假设”、“理解”、“非初始化”、“农民感知”、“气候变化”、“适应”、“利用”、“改善”、“适应能力”、“后果”。l 'aide d何谓combinaison数据定性问题d 'entretiens用des informateurs cl, de groupe et de讨论数据secondaires d 'organismes gouvernementaux, le当前文档revele, les agriculteurs percoivent de坟墓个倒他们健康和他们的办法生存,在一个connaissance depit limitee de la方式不le换向机构的避暑se产品。本文结合了农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,农业发展的质量问题,气候变化的质量问题。将对气候条件的变化进行勘测,并对相当大的气温和降水的影响进行勘测,因此,在审批过程中会产生严重的问题。人类的活动、农业活动和社会平等威胁着人类的生存,对相互依赖的物种造成了严重的影响,对文化造成了严重的破坏,对掠夺者造成了严重的侵害,对农业生产造成了严重的减少。因此,利用系统化、措施化、适应化、社区化、响应化、气候变化化、种植化、新文化多样性、技术和农药的利用、农业技术的利用、收入和管理的多样化。除此之外,“资源融资模式”为“新技术的利用者”和“适应技术”提供了“新技术的利用者”、“新技术的利用者”和“新技术的利用者”提供了“新技术”。这些结果表明,不努力加上自觉的转变,将形成适应战略和气候变化战略,并形成长期的适应措施和气候变化措施。气候变化;适应;les agriculteurs;农业;菲律宾

Cassava plays a major role in households’ food and income security in Democratic Republic of Congo (DRC). Despite multiple efforts to overcome the problem of low productivity in cassava production through the introduction of improved technologies, the level of adoption of such technologies by farmers has remained low in eastern DRC. This study, therefore, aimed at identifying determinants of adoption and farmers' preferences for cassava varieties in Kabare Territory, eastern DRC. A participatory approach was used to collect data on 250 cassava smallholder farmers in five different zones called “groupements” including Cirunga, Kagabi, Bugorhe, Katana, and Mumosho. Results showed that improved cassava varieties are adopted by 28.8% of smallholder farmers. Membership in an agricultural cooperative, access to planting material as a credit, education level, gender, and cropping system had a positive influence on improved varieties’ adoption. In contrary, field-to-house distance, location and total farm size had a negative effect on adoption decision. This study demonstrated that introduced varieties possess most of traditional desirable traits (yield potential, taste, high disease resistance and early maturity) but are lacking local (regional) farmers’ preferences such as leaf production, in-soil storage, bitterness, tuber color which had limited adoption by farmers who continue relying on local landraces (88%) for those traits. Therefore, in addition to addressing negative factors that prevent adoption, specific attention should be given by cassava breeders to local specific preferences if the objective is to increase adoption of improved varieties by farmers in eastern DRC.
在刚果民主共和国,木薯在家庭粮食和收入安全方面发挥着重要作用。尽管多方努力通过引进改良技术来克服木薯生产生产率低的问题,但在刚果民主共和国东部,农民采用这类技术的水平仍然很低。因此,本研究旨在确定刚果民主共和国东部Kabare地区采用木薯品种的决定因素和农民对木薯品种的偏好。采用参与式方法收集了来自Cirunga、Kagabi、Bugorhe、Katana和Mumosho五个不同区域的250名木薯小农的数据,这些区域被称为“小组”。结果表明,28.8%的小农采用改良木薯品种。农业合作社的成员资格、获得种植材料的信贷、教育水平、性别和种植制度对改良品种的采用有积极影响。相反,田间到家庭的距离、地点和农场总规模对收养决定有负面影响。该研究表明,引进品种具有大多数传统的理想性状(产量潜力、味道、高抗病性和早熟),但缺乏当地(区域)农民的偏好,如叶片产量、土壤储存、苦味、块茎颜色,这些性状被继续依赖当地地方品种的农民所采用(88%)。因此,除了解决阻碍采用的负面因素外,如果要提高刚果民主共和国东部农民对改良品种的采用,木薯育种者还应特别关注当地的特定偏好。

Despite multiple efforts to overcome the problem of low productivity in cassava production through the introduction of improved technologies, the level of adoption of such technologies by farmers has remained low in eastern DRC. This study, therefore, aimed at identifying determinants of adoption and farmers' preferences for cassava varieties in Kabare Territory, eastern DRC. A participatory approach was used to collect data on 250 cassava smallholder farmers in five different zones called “groupements” including Cirunga, Kagabi, Bugorhe, Katana, and Mumosho. Results showed that improved cassava varieties are adopted by 28.8% of smallholder farmers. Membership in an agricultural cooperative, access to planting material as a credit, education level, gender, and cropping system had a positive influence on improved varieties’ adoption. In contrary, field-to-house distance, location and total farm size had a negative effect on adoption decision. This study demonstrated that introduced varieties possess most of traditional desirable traits (yield potential, taste, high disease resistance and early maturity) but are lacking local (regional) farmers’ preferences such as leaf production, in-soil storage, bitterness, tuber color which had limited adoption by farmers who continue relying on local landraces (88%) for those traits. Therefore, in addition to addressing negative factors that prevent adoption, specific attention should be given by cassava breeders to local specific preferences if the objective is to increase adoption of improved varieties by farmers in eastern DRC.","PeriodicalId":45379,"journal":{"name":"Journal of Rural and Community Development","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2019-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85940605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the economic impact of grain storage structures and storage duration on the income of rural farmers in Kogi State, north-central, Nigeria. The study utilised the questionnaire method, supported by on-site observation and interactions with key players along the grain supply chain. Multistage sampling was used to select three hundred (300) rice and maize farmers spread across fifty (50) communities in the State that participated in the research. The results show that the storage systems and length of storage of the farm produce (maize and rice) has a significant impact on the annual income of the farmers, and only 1 per cent of the grain farmers’ population earned above the 2017 world’s poverty benchmark. We found out that access to technology for agricultural purposes was zero. The major challenges reported by the farmers are; poor processing/storage facilities (43.4 %), poor sales after harvest (30.3 %) and lack of agricultural credits (23.3 %). The existing storage structures encourages post-harvest waste and losses, affecting the quality of stored grains and invariably its market value and farmers’ income; the grain market is erratic with middlemen dictating the price of grains. None of the farmers surveyed had accessed agricultural credit at any time. The study recommends shared or communal storage centres for each of the communities, where farmers can either have their grains sold at Guaranteed Minimum Price or with an option to store the grains in anticipation of better prices in the future. Bank Accounts would be opened for the farmers, and a Grain Card would be issued to help keep and build the farmers’ “Activity Ratings” for economic purpose like credit assessment to determine eligibility for agricultural credit. Private firms should manage the shared or communal centre in each community in a public-private partnership with the government, but the farmers should be shareholders by default. The shared or communal centres should also be a reliable intermediary between the farmers and other key stakeholders, strengthening the rural economic institution, and serving as a training centre for the rural farmers. A theoretical shared or communal storage model was designed.
本研究考察了粮食储存结构和储存时间对尼日利亚中北部科吉州农村农民收入的经济影响。该研究采用问卷调查法,并辅以现场观察和与粮食供应链上的关键参与者的互动。采用多阶段抽样方法,选择了分布在该州50个社区的300名种植水稻和玉米的农民参与了这项研究。结果表明,农产品(玉米和大米)的储存系统和储存时间对农民的年收入有重大影响,只有1%的粮食农民的收入超过2017年世界贫困基准。我们发现获得农业技术的机会为零。农民报告的主要挑战是;加工/储存设施差(43.4%),收获后销售不佳(30.3%),缺乏农业信贷(23.3%)。现有的储存结构助长了收获后的浪费和损失,影响了储存谷物的质量,并始终影响其市场价值和农民的收入;粮食市场不稳定,中间商决定粮食价格。接受调查的农民中没有一个在任何时候获得过农业信贷。该研究建议为每个社区建立共享或公共储存中心,在那里农民可以以保证最低价格出售他们的谷物,也可以选择储存谷物以预期未来更好的价格。将为农民开设银行账户,并发放粮食卡,以帮助保持和建立农民的“活动评级”,用于信用评估等经济目的,以确定农业信贷的资格。私人公司应该与政府以公私合作的方式管理每个社区的共享或公共中心,但农民应该默认为股东。共享或社区中心还应成为农民和其他关键利益相关者之间的可靠中介,加强农村经济机构,并作为农村农民的培训中心。设计了一个理论上的共享或公共存储模型。
