The objective of this study is to determine factors affecting the technical efficiency of the inshore fisheries in Kuala Terengganu. Data for the study was collected from a survey conducted between June and August 2007 where 100 fishermen in 14 villages were chosen by stratified sampling. Data envelopment analysis (DEA) and Tobit analysis were employed to determine the technical efficiency level and factors influencing technical efficiency among the fishermen. Results of the study show that, most fishing units exhibit a low degree of technical efficiency. This implies that either fishing inputs were used inefficiently or insufficient inputs were used in fishing activities. The mean technical efficiency for the sample was estimated to be 55% for the peak season and 40% for the non peak season. About 37% and 62% of the fishermen had less than 40% level of technical efficiency in peak season and non peak season respectively. Management variables (planning, staffing and controlling) and demographic variables (size of horsepower, size of family and formal education) exert positive effects on technical efficiency of inshore fisheries in Kuala Terengganu. These findings suggest that there is much room for improvement in efficiency among a large segment of the inshore fishermen. With appropriate training and using more advanced technologies, fishermen’ level of technical efficiency can be raised.
本研究的目的是确定影响瓜拉丁加奴近岸渔业技术效率的因素。本研究的数据收集于2007年6月至8月期间进行的一项调查,该调查采用分层抽样的方法选择了14个村庄的100名渔民。采用数据包络分析(DEA)和Tobit分析确定渔民的技术效率水平和影响技术效率的因素。研究结果表明,大多数捕鱼单位的技术效率程度较低。这意味着捕鱼投入要么使用效率低下,要么在捕鱼活动中使用的投入不足。样本的平均技术效率在旺季估计为55%,在非旺季估计为40%。在淡季和非淡季,分别有37%和62%的渔民技术效率低于40%。管理变量(规划、人员配备和控制)和人口变量(马力大小、家庭规模和正规教育)对瓜拉丁加奴近岸渔业的技术效率有正向影响。这些发现表明,在很大一部分近岸渔民中,效率还有很大的提高空间。通过适当的培训和使用更先进的技术,渔民的技术效率水平可以提高。

Study of Effective Factors on Income Inequality Decrease in Rural Areas of Iran 伊朗农村收入差距缩小的影响因素研究
Pub Date : 2012-03-01 DOI: 10.22004/AG.ECON.147582

According to the Ahlowalia hypothesis (1995), the growth of total factor productivity (TFP) beside infrastructure investments of government lead to income inequality decrease in rural areas of countries. The main objective of this study is to investigate the effects of public investments such as agricultural R&E, road, education and irrigation on income inequality in rural areas of Iran. In order to get results, we used ARDL method and time series data of 1980 to 2008. However, this research attempts to survey the direction of causality between the income inequality and total factor productivity (TFP) in Iran. Empirical results show there is a negative relation between income inequality and agricultural TFP in rural areas of Iran. Hence, additional investments on rural education and agricultural R&E have significance and different impacts on income inequality. Findings showed Ahlowalia hypothesis developed for the relation among income inequality, TFP and investment in electricity is not rejected in case of Iran`s rural areas.
根据Ahlowalia假说(1995),除了政府的基础设施投资外,全要素生产率(TFP)的增长会导致国家农村地区收入不平等的减少。本研究的主要目的是调查公共投资(如农业R&E、道路、教育和灌溉)对伊朗农村地区收入不平等的影响。为了得到结果,我们使用了ARDL方法和1980 - 2008年的时间序列数据。然而,本研究试图调查伊朗收入不平等与全要素生产率(TFP)之间的因果关系方向。实证结果表明,伊朗农村地区收入不平等与农业全要素生产率呈负相关。因此,农村教育和农业r&d的额外投资对收入不平等具有显著性和不同的影响。研究结果表明,对于伊朗农村地区,Ahlowalia提出的收入不平等、全要素生产率和电力投资之间关系的假设并不被否定。

Rural households in Nigeria are vulnerable to shock because of their limited capacity to make informed decision on secured coping strategies which is further aggravated by some households’ specific socio-economic characteristics. Attempts were made to identify shocks being faced by households’ heads and coping strategies. Multistage sampling technique was used to select 80 respondents and well structured questionnaire was used to collect data through in-depth interview. Data were analysed using descriptive statistics to describe households’ socio- economic variables; Probit analysis was also used to determine the relationship between personal socio-economic characteristics of the respondents, shocks and choice of coping actions. The results revealed that a large share of households experience multidimensional shocks, which are mainly associated to ecological but also suffer from other economic, demographic and social factors. Majority of households undertake coping actions in response to shocks; coping strategies employed but not limited to include borrowing, distress sales of assets, remittances, adjustment in food intake, drawing on savings. Educational status, household size, per capita income, shocks type, coping strategies, among others are found to significantly affect the choice of coping actions and are likely to have implications for households’ future welfare status.
尼日利亚的农村家庭很容易受到冲击,因为他们对有保障的应对策略做出知情决定的能力有限,而一些家庭的特定社会经济特征进一步加剧了这种情况。我们试图找出户主所面临的冲击和应对策略。采用多阶段抽样技术,选取80名受访者,采用结构合理的问卷,通过深度访谈收集数据。数据分析采用描述性统计描述家庭的社会经济变量;Probit分析还用于确定受访者的个人社会经济特征、冲击和应对行动选择之间的关系。结果表明,很大一部分家庭经历了多维冲击,这些冲击主要与生态有关,但也受到其他经济、人口和社会因素的影响。大多数家庭采取应对行动应对冲击;所采用的应对策略包括但不限于借款、变卖资产、汇款、调整食物摄入量、动用储蓄。研究发现,教育程度、家庭规模、人均收入、冲击类型、应对策略等因素显著影响应对行动的选择,并可能对家庭未来的福利状况产生影响。

The Farmers of the Future (FoF) initiative implemented a programme of integrating natural resources management in the basic education curriculum. The purpose of the study was to document activities and determine the effects of FoF programme on primary school learners’ perceptions towards natural resources management by comparing learners involved in the FoF programme and those not involved. Further, comparison of perceptions by gender among learners involved in the FoF was done. The study employed an ex-post-facto design. The location of the study was the western region of Kenya. The sample was composed of 120 learners and 6 teachers, making a total of 126 respondents. This was in accordance with recommendations by Kathuri and Pals (1993). The data were collected using questionnaires and analysed using t-test at alpha = 0.05. The instruments were validated by two experts in the Department of Agricultural Education and Extension at Egerton University and one expert from ICRAF. Reliability was tested through pilot testing and indicated a reliability coefficient of 0.72 The findings indicated that the FoF programme had a significant influence on learners’ positive perceptions towards natural resources management thus the programme forms an integral part in sustainable agriculture.

Globalization is integration of national economies in global economy and infers on increasing the flow of goods and services. In this study the consequences of globalization were studied through the analysis of Level of International Trade index (LIT) in the caviar export equation. The required data were gathered from Statistical Yearbook of Foreign Trade, Statistical Yearbook of fisheries, Statistical Yearbook of the International Monetary Fund, United Nations Food and Agriculture Organization and different issues of Central Bank of Iran over 1974-2007. The results showed that domestic production of caviar have significant and positive effects on its export. In addition, sign of level of international trade variable in the estimated model is positive and indicates trade restrictions remove lead to increase in caviar export.
全球化是各国经济在全球经济中的一体化,是指商品和服务流动的增加。本研究通过分析鱼子酱出口方程中的国际贸易水平指数(LIT)来研究全球化的后果。所需数据收集自1974-2007年《对外贸易统计年鉴》、《渔业统计年鉴》、《国际货币基金组织统计年鉴》、《联合国粮食及农业组织统计年鉴》以及伊朗中央银行的不同刊物。结果表明,国内生产鱼子酱对出口有显著的积极影响。此外,估计模型中国际贸易变量水平的符号为正,表明贸易限制的取消导致了鱼子酱出口的增加。

The study sought to determine whether pastoralists have resorted to sale of livestock as a form of insurance against commercialization of cattle rustling in which well structured and managed cartels have organised more intense and frequent cattle raids on pastoralist, and how their decisions have affected their herd size. The study was conducted among the pastoral Baringo community of Kenya. A sample size of 110 households was selected using multi-stage sampling procedures and interviewed using a questionnaire. Binary Probit Model and Ordinary Least Squares were used in the analysis. Results indicated that cattle rustling, particularly in its predatory state significantly contributes to spontaneous sale of livestock even under very low prices that in themselves could be described as raiding. The results further indicated that the number of livestock lost through cattle rustling dominated livestock sale and hence reduced herd size and the numbers of livestock available for sale. The insecurity generated by cattle rustling, coupled with the poor marketing infrastructure make market inaccessible by both buyers and sellers, resulting to increased poverty and dependency amongst the pastoralists. Consequently, pastoralism has become a source of misery rather than source of livelihood.
该研究试图确定牧民是否将牲畜出售作为一种保险形式,以防止盗牛商业化,在这种情况下,结构良好和管理良好的卡特尔组织对牧民进行更激烈和频繁的牛袭击,以及他们的决定如何影响他们的牛群规模。这项研究是在肯尼亚的巴林戈牧民社区进行的。采用多阶段抽样方法,选取110户家庭为样本,采用问卷调查方式进行访谈。采用二元概率模型和普通最小二乘法进行分析。结果表明,盗牛行为,特别是在其掠食性状态下,显著地促进了牲畜的自发销售,即使在非常低的价格下,这本身可以被描述为突袭。结果进一步表明,因偷牛而损失的牲畜数量主导了牲畜销售,从而减少了畜群规模和可供销售的牲畜数量。偷牛造成的不安全,加上糟糕的销售基础设施,使得买卖双方都无法进入市场,导致牧民更加贫困和依赖。因此,畜牧业已成为痛苦之源,而不是生计之源。

In this study, the situation of Iran, U.S and Turkey's Pistachio export is investigated. to this purpose, Revealed Comparative Advantage (RCA) Index is calculated based on Agricultural and total economy export, separately, then forecasted by using Auto- Regressive Integrated Moving Average (ARIMA) approached, for 2008-2013. The results show that considering both commodity baskets, Turkey and Iran had comparative advantage in Pistachio export in 1982-2007, but U.S did not. Also, forecasting RCA index, based on both commodity baskets, show the improvement of U.S Pistachio export situation, unlike the values of RCA index forecasting for Iran and Turkey is falling. Therefore, it is recommended that Iran and Turkey attempt to identify new consumer markets in order to retain their market shares in pistachio export. Following the U.S imposed policies during last six years which improved its pistachio export, Iran and Turkey can increase their market shares.
本研究以伊朗、美国和土耳其的开心果出口情况为研究对象。为此,本文分别计算了2008-2013年农业和经济总量出口的显示比较优势指数(RCA),并采用自回归综合移动平均(ARIMA)方法进行了预测。结果表明,考虑到两种商品篮子,土耳其和伊朗在1982-2007年开心果出口上具有比较优势,而美国没有。此外,基于两种商品篮子的RCA指数预测显示,美国开心果出口情况有所改善,而伊朗和土耳其的RCA指数预测值则有所下降。因此,建议伊朗和土耳其尝试寻找新的消费市场,以保持其在开心果出口中的市场份额。随着美国在过去六年中实施的政策改善了其开心果的出口,伊朗和土耳其可以增加其市场份额。

The Nigerian rice sector has made remarkable improvement in the last decade as production has increased significantly thereby reducing the gap between domestic supply and demand. In the last three decades, rice imports make up greater proportion of Nigerian imports as rice forms a structural component of the Nigerian diet. Past government inconsistent policies were not successful in securing good market share for domestic rice producers, hence producers suffered great losses. The recent resurgence of interest by the present administration to intensify domestic rice production has yielded positive results. The objective of this study is to analyze and assess the costs and benefits of intensification of rice production systems in southeastern Nigeria using a policy analysis matrix approach. Multi Stage sampling technique was employed in selecting 75 upland and 75 lowland rice farmers who were interviewed with structured and validated questionnaire. Data were analyzed using Policy Analysis Matrix (PAM). The result shows that upland; lowland and double rice cropping systems in southeastern Nigeria are profitable based on the policy analysis matrix (PAM) model, and rice production under various systems and technologies is socially profitable and financially competitive. While there exist comparative advantage in the various production systems, with lowland and double cropping being highest, substantial tax was imposed on rice imports in Nigeria and government investment in intensifying rice production had a positive impact on the output of local rice production. The study concludes with strategies for the development of rice sub sector in Nigeria.
尼日利亚稻米部门在过去十年中取得了显著的进步,产量大幅增加,从而缩小了国内供需之间的差距。在过去三十年中,大米进口占尼日利亚进口的较大比例,因为大米是尼日利亚饮食的结构性组成部分。过去政府不一致的政策未能成功地为国内大米生产商确保良好的市场份额,因此生产商遭受了巨大的损失。本届政府最近对加强国内稻米生产的兴趣重新抬头,产生了积极的结果。本研究的目的是利用政策分析矩阵方法分析和评估尼日利亚东南部水稻生产系统集约化的成本和效益。采用多阶段抽样方法,选取75名旱地稻农和75名低地稻农,采用结构化的有效问卷进行访谈。采用策略分析矩阵(PAM)对数据进行分析。结果表明:高地;根据政策分析矩阵(PAM)模型,尼日利亚东南部的低地和双作水稻制度是有利可图的,各种制度和技术下的水稻生产具有社会效益和财政竞争力。虽然在各种生产系统中存在着比较优势,其中低地和双季种植是最高的,但尼日利亚对大米进口征收了大量税收,政府在加强大米生产方面的投资对当地大米生产的产量产生了积极影响。该研究总结了尼日利亚水稻分部门的发展战略。

In the last three decades, rice imports make up greater proportion of Nigerian imports as rice forms a structural component of the Nigerian diet. Past government inconsistent policies were not successful in securing good market share for domestic rice producers, hence producers suffered great losses. The recent resurgence of interest by the present administration to intensify domestic rice production has yielded positive results. The objective of this study is to analyze and assess the costs and benefits of intensification of rice production systems in southeastern Nigeria using a policy analysis matrix approach. Multi Stage sampling technique was employed in selecting 75 upland and 75 lowland rice farmers who were interviewed with structured and validated questionnaire. Data were analyzed using Policy Analysis Matrix (PAM). The result shows that upland; lowland and double rice cropping systems in southeastern Nigeria are profitable based on the policy analysis matrix (PAM) model, and rice production under various systems and technologies is socially profitable and financially competitive. While there exist comparative advantage in the various production systems, with lowland and double cropping being highest, substantial tax was imposed on rice imports in Nigeria and government investment in intensifying rice production had a positive impact on the output of local rice production. The study concludes with strategies for the development of rice sub sector in Nigeria.","PeriodicalId":13735,"journal":{"name":"International Journal of Agricultural Management and Development","volume":"1 1","pages":"89-100"},"PeriodicalIF":0.0,"publicationDate":"2011-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68514109","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}

The purpose of this research was identifying socio-economic characteristics affected on respondents’ participation in contract farming. The survey was conducted using structured questionnaire in populous states namely Kedah, Kelantan, Terengganu, Pahang, Perak, Selangor and Johor in Peninsular Malaysia. A total of one-hundred and sixty seven FFV farmers were randomly selected and personally interviewed. Logit analysis was carried out to identify determinants that influenced fresh fruits and vegetables (FFV) farmers participating in contract farming. The findings in the paper show that, based on the output from logistic regression, ownership, land size, education background, perceived benefit, complicated process, lacking in opportunities and price risk are dominant variables influencing FFV farmers’ willingness to participate in contract farming. Land ownership, land size, education and perceived benefit are dominant variables that positively influenced FFV farmers to participate in contract farming. Complicated process, lack of opportunities and price risk negatively influenced FFV farmers’ participation in contract farming.
本研究的目的是确定影响受访者参与承包农业的社会经济特征。这项调查是在马来西亚半岛的吉打州、吉兰丹州、登嘉楼州、彭亨州、霹雳州、雪兰莪州和柔佛等人口众多的州进行的。随机选取167名FFV农户进行个人访谈。进行了Logit分析,以确定影响新鲜水果和蔬菜(FFV)农民参与合同农业的决定因素。本文的研究结果表明,从logistic回归的结果来看,所有权、土地规模、教育程度、感知利益、过程复杂、缺乏机会和价格风险是影响FFV农户参与合同农业意愿的主导变量。土地所有权、土地规模、教育程度和感知利益是影响FFV农户参与合同农业的主要变量。流程复杂、缺乏机会和价格风险对FFV农户参与合同农业产生了负面影响。

In the present study Iran's rice imports trend is forecasted, using artificial neural networks and econometric methods, during 2009 to 2013, and their results are compared. The results showed that feet forward neural network leading with less forecast error and had better performance in comparison to econometric techniques and also, other methods of neural networks, such as Recurrent networks and Multilayer perceptron networks. Moreover, the results showed that the amount of rice import has ascending growth rate in 2009-2013 and maximum growth occurs in 2009-2010 years, which was equal to 25.72 percent. Increasing rice import caused a lot of exchange to exit out of the country and also, irreparable damage in domestic production, both in terms of price and quantity. Considering mentioned conditions, economic policy makers should seek ways to reduce increasing trend of rice import; and more investment and planning for domestic rice producers.
本文运用人工神经网络和计量经济学方法对2009 - 2013年伊朗大米进口趋势进行了预测,并对预测结果进行了比较。结果表明,与计量经济学技术和其他神经网络方法(如循环网络和多层感知器网络)相比,脚前神经网络具有更小的预测误差和更好的性能。结果表明:2009-2013年,我国大米进口量呈上升趋势,其中2009-2010年增幅最大,为25.72%;大米进口的增加导致大量外汇流出该国,也对国内生产造成了不可弥补的损害,无论是在价格上还是在数量上。考虑到这些情况,经济政策制定者应该寻求减少大米进口增加趋势的方法;对国内大米生产商进行更多的投资和规划。
