This paper aims to form a hypothesis about factors that affect the dietary lives in mother-to-child households by qualitatively analyzing information obtained from face-to-face interviews about the current daily lives in these households and the dietary lives experienced by the mothers in their childhood. We conducted semi-structured interviews ranging from one and a half to two and a half hours long with eight mothers from mother-to-child households living in the Hanshin region, all of whom were either introduced directly by NPO organizations or by other interviewed mothers. Although all participants were experiencing economic hardships in their daily lives, their educational attainment was high and their childhood dietary life was good. Since they were trying to provide their children with well-balanced meals at regular times, their children generally enjoyed a favorable dietary life. However, almost all of the participants who had to work to support their families in addition to undertaking various domestic duties on their own suffered from mental instability and chronic fatigue as a result of objectively limited time, along with negative experiences-such as divorce and harassment from ex-husbands-and anxiety about the future. In addition, they felt strongly that their time is limited subjectively due to mental instability, poor physical conditions, insufficient family support, and/or objectively limited time. In the case of mental instability and/or poor physical conditions, it can be difficult for individuals to perform domestic duties, such as cooking and shopping, which can temporarily aggravate the dietary intake of mothers themselves as well as their children. Therefore, emergency support measures, such as social safety nets for mother-to-child households, should be strengthened to counteract these negative effects of mental instability and/or poor physical conditions in daily life.

This study aims to clarify the characteristics of dietary awareness and eating behavior peculiar to children and mothers in mother-to-child households. We conducted quantitative analyses using individual data from several large sample surveys. The major findings of the statistical analyses are as follows: (1) Junior high school students from mother-to-child households are more likely to skip breakfast than their counterparts from two-parent households. In addition, mothers from mother-to-child households are more likely to skip meals and less likely to have a nutritionally balanced diet, pay attention to food safety, and spend time on housework, compared with mothers from two-parent households. This may be attributed to the fact that such mothers tend to work longer hours to support their families and must do many things on their own. (2) Adults who have grown up in mother-to-child households are more likely to skip breakfast in their adulthood, given their childhood habit of skipping breakfast.

This study aims to investigate the food security situation, and to identify the determinants of household food security in the rain-fed lowland rice farms in the rural areas of Lao PDR. We interviewed 88 households using a semi-structured questionnaire in two rural areas of Pathoumphone district, Champasak province. We used a daily calorie intake as an indicator of food security, and a logistic regression model to examine the factors influencing household food security. The result of this study showed that the average calorie intake per capita was 1,815 kcal per day, in which 88% derived from rice. On the other hand, other food such as meat, eggs, oils and fat are eaten in small portion. As a result, about 55% of the respondents were food insecure. The empirical model showed that dependency ratio, rice yield, number of relatives, and rice-farming experience were significantly correlated to food security. Thus, policy interventions should consider on social network and per-hectare yield to improve food security in the rural rain-fed lowland rice areas.

Customer satisfaction is the most important element for developing and sustaining organizational priorities and practices. Thus, we examined farmers' overall satisfaction with agricultural extension services and its determinants using data collected from 150 beneficiary farmers in North West Ethiopia. The findings show that about 55 percentage of the interviewees were satisfied whereas 45 percentage of them were dissatisfied with the extension services, implying that the program still has a lot of room for improvement. The empirical result based on ordered logit model revealed that perceived economic return, regular extension contact, family size and off-farm income were driving factors for farmers' satisfaction. On the other hand, limited technology choices, high price of inputs, inconvenient loan system and undefined boundary between the extension services and the local politics were among the reasons given by dissatisfied farmers. Thus, from a policy perspective, the findings suggest a need to develop demand-driven extension service instead of the existing supply-driven one. Such service should be aiming to enhance the rewards from farming in order to maintain participation and farmers satisfaction, which influence the sustainability of the extension program.

Salt production is a major driving force behind the loss of mangrove in Guinea. As the traditional salt production causes increasing deforestation, the intensive exploitation of mangrove resources has now reached a critical threshold. Therefore, improved techniques using sunlight as the source of energy has been introduced as an alternative to the traditional salt production techniques which consumes a significant amount of mangrove wood. Therefore, it's of interest to examine the efficiency of the new salt production technique, in this an attempt is made to determine the technical efficiency of salt producers adopting the improved techniques by using the stochastic frontier analysis method. The study used primary data collected through a survey. A sample of 100 salt producers was interviewed during March-April 2013. However, this study considers only 65 producers using the improved salt production techniques along the Guinean coast in Koba, particularly in Balessourou district. The results revealed that labor cost and dimension of the basins contribute to enhance the performance of salt production in terms of revenue earned. Inefficiency model indicated that membership in salt producer organizations, producers' participation in activities organized by local and/or international institutions family size and land rent significantly influenced technical inefficiency. Results also highlighted the fact that even the best producers were inefficient. The mean level of their technical efficiencies was estimated at 27%, while the efficiency ranged from 0.0 to 92%. In addition, the estimation of the loss due to the inefficiency occurring seasonally was significant and valued at 601,024 Guinean francs per basin. In order to improve the efficiency of salt production, this study advocates some strategies such as coating basins for minimizing the loss of salt during extraction, encouraging producers' participation in activities organized by the government and its partners and strengthening producers' organizations to enhance producer participation in salt production. © 2014 Science Publication.

Teff (Eragrostistef) is a major staple food crop in Ethiopia, but smallholder teff production is characterized by persistently low average yield. A major government effort aimed at raising the productivity and competitiveness of smallholder agriculture in Ethiopia involved reforming and implementing agricultural extension service known as Participatory Demonstration and Training Extension System (PADETES). Therefore, this study investigates the effect of agricultural extension service and other factors on the Technical Efficiency (TE) of teff producers in northern Ethiopia. Using cross sectional data we compare TE level of teff producers who are participants and non-participants of Agricultural Extension (AE) program. We address self-selection in to AE program participation using propensity score matching method. Translog stochastic frontier production function is used for TE analysis. The empirical results reveal that, AE program participants' and non-participants' farms have an average TE of 72 and 71% respectively. Both groups of farms have considerable overall technical inefficiencies, suggesting the existence of immense potentials for enhancing production through more efficient use of available technology and resources. Determinants of TE are explained significantly by livestock ownership, credit and improved seed. Based on the results, we derive policy recommendations to improve farmers' teff production performance. These policy measures include the provision of extension services related to technical skill and farm management capacity of the farmers, demand driven livestock extension service, greater access to credit and increasing the availability, quality and adoption of improved seed. © 2014 Science Publication.

本稿では,第4次インドネシア家族生活調査の個票データを用いて,ジャワ島における既婚女性の主観的自立性と世帯の食料消費支出額との関係を明らかにすることを目的とした。家計支出に関する意思決定力を自律性の代理変数として分位点回帰を用いて分析した結果,低中位支出階層―とくに最貧層―では,家計支出に関する既婚女性の意思決定力が野菜類・果物類・魚類・肉類・乳製品類の1人当たり消費支出額にプラスの影響を及ぼすことが明らかとなった。また中位支出階層では,既婚女性と夫が協力して意思決定をしている世帯は,既婚女性のみが意思決定をしている世帯よりもさらに食料支出額は高くなる傾向が認められた。こうした分析結果から,低中位階層―とくに最貧層―のフードセキュリティを改善するうえで,家庭内における女性の自律性や意思決定力を高める施策が効果的であると考えられる。さらに中位階層については,家計支出の決定に妻とともに夫も関与するように促す啓発活動を推進していくことでより効率的な政策効果が期待される。

This article clarifies factors affecting the level of household food security, measured on a subjective basis, in a mountainous area of central Java. Results of our analysis clearly indicate that economic shock affects negatively household food security, and relation networks, size of cultivated area, number of off-farm workers outside the village, numbers of clove trees and the varieties of crops create a positive influence. In addition, regardless of the cultivated area, there is a positive relation between household food security and the numbers of trees and varieties of crops. The findings indicate that agroforestry systems combining cash tree crops and annual food crops can improve household food security in mountainous areas.

The economy of Pakistan is predominantly agrarian, and optimum utilization of water resources is of paramount importance. Poor production and inefficiency of the farmers are among the main causes of food problem. Searching for appropriate ways to increase productivity and efficiency are important for individual household welfare as well as for country economy. Therefore, this study aimed to compare the productive performance of the improved irrigation channels made from cement concrete as well as stones and traditional channels made from mud and stones of irrigation systems using a stochastic frontier production (SFP) technique involving a model for technical inefficiency effects. A total of 77 farmers were selected by using systematic random technique from two villages, Sultanabad and Parri, from the Gilgit district of Pakistan. Household heads were interviewed through semi-structured questionnaire to collect overall data on farming systems. SFP function was used to estimate the effect of different variables on the crops technical efficiency (TE). Results show significantly positive effect of improved irrigation system ([IS) for wheat and vegetable crops on the TE of the crop producing farms. A high degree of technical inefficiency in wheat and vegetables farming for the traditional irrigation system (TIS) has been reported, which is clue to factors under farms control. It has been argued that wheat and vegetables cultivating farms in the TIS can increase production by 28% and 18%, respectively, via upgrading the TIS to the IIS with irrigation development. However, farmers operating under IIS are more efficient as compared to TIS. Hence, improving productivity requires introduction of a new technology.

The overriding objective of this paper is to clarify changes in household food consumption expenditure after the 1997/98 Asian Economic Crisis, with special reference to Peninsular Malaysia (West Malaysia). We estimated Engel's expenditure elasticities for food items using aggregated cross-sectional data from the 1993/94, 1998/99 and 2004/05 Household Expenditure Surveys. The estimated results clearly indicate that the expenditure elasticities of away-from-home food for upper and middle classes increased after the Asian Economic Crisis. In addition, we found that elasticities of at-home expenditures for meat, fruits and vegetables, milk and dairy products are relatively high, those of rice is low. These findings suggest that the food expenditure structure in Peninsular Malaysia has diversified.

いくつかの途上国では、経済発展に伴う所得向上によって鶏肉消費が急速に拡大しており、養鶏経営の大規模化や垂直統合が進みつつある。しかし管見の限りでは、途上国における大規模養鶏経営の収益性や持続性については十分に実態調査が行われていない。そこで本稿では、鶏肉生産が急拡大しているネパール・チットワン郡の平野部を調査地として養鶏業者の経営データを詳細に検討することによって、大規模養鶏経営の収益性と持続性を明らかにすることを主たる目的とした。年間96,000羽(2カ月聞に16,000羽×年6回飼育)のブロイラーを飼育している大規模養鶏業者の経営分析を行ったところ、次のような結果を得た。調査対象の大規模養鶏業者によると、資材供給会社は一部後払いで鶏雛や養鶏用飼料を供給してくれると同時に、成鶏の出荷先も確保してくれるとのことであった。この事実から、ネパールの調査地における養鶏業においても、ある程度の垂直統合が進んでいると推察される。貸借対照表を作成した結果、資産額と負債額は各々459.9万ルピー(1ルピー=1.5 円~1.6円)と122.5万ルピーであり、純資産額は337.4万ルピーであることが明らかとなった。また養鶏の損益計算から、年間収益は100万ルピー程度であると推定できる。これに加えて、財務比率、流動性比率、ソルベンシー比率、投資の収益率等の各評価値も概ね良好であった。さらに、内部収益率が市場利子率と要求収益率(required rate of return)を上回っていること、損益比率が1を上回っていること、投入資材の価格上昇などの悪条件に対して脆弱でないという感度分析の結果なども勘案すると、ネパールの調査地における大規模養鶏経営は収益性が高くかつ持続性があると考察できる。

This article clarifies the factors determining the differences in efforts toward fresh fish branding among fisheries cooperative associations in Nagasaki Prefecture. Our analysis, based on questionnaire survey data of 44 fisheries cooperative associations, clearly suggests that the more volume of high quality fresh fish are available in a certain quantity, the fisheries cooperative associations are more likely to engage in fresh fish branding.

The underpin issues of the study are to examine the farm level inorganic fertilizers (urea, TSP and MP known as primary plant nutrients) use, their determinants and suggest policy remark(s) at new circumstances of policy reform in inorganic fertilizers market in Bangladesh. The findings of the study reveal that the farmers were using excessive urea and comparatively fewer amounts of TSP and MP and those farmers were using comparatively more TSP and MP, in contrast they were using less amount of urea. The estimated results of determinant functions indicate that the use of TSP and MP at the farm level could be increased by reducing their prices and increasing the urea price at the farm level, simultaneously. Side by side, massive extension program regarding the balance fertilizers use could also increase the use of these two fertilizers at farm level and the use of better combination of TSP and MP alone with urea might reduce the tendency of using more urea. The mean of reducing prices of TSP and MP at farm level is to provide price subsidy in the country. To overcome the budgetary constrain, government of Bangladesh could increase the urea price and earn extra revenue. And this extra revenue earned from urea sale could be provided as price subsidy for TSP and MP in the country. © 2007 Academic Journals.

Management reforms are considered one of the best alternatives in increasing efficiency of the irrigation systems. Transfer of day-to-day operation and maintenance to farmers is not a new concept. However due to lags, even now it is a hot issue in developing countries and Nepal is not an exception. In this context of growing argument about the transfer of management of public irrigation systems to the Water Users' Group, this paper examines the comparative performance of farmer-managed and agency-managed irrigation systems. Khageri Irrigation System in the Chitwan district of Nepal was taken as the study site where complete management transfer has been done in 1996. The situations before and after complete transfer were compared. Intensive case studies of the selected farmers showed that equity in distribution of water and leakage had significantly improved after management transfer. Logit analysis revealed that age and education level of the household head, distance from main canal, leakage of the canal and equity in distribution are significantly related to the satisfaction level of the beneficiary farmers from FMIS compared to AMIS. However, landholding size of the respondent farmer has no significant effect. Similarly results from t-test revealed that rice productivity and overall profits from agriculture has also increased significantly due to irrigation management transfer. © Springer Science+Business Media, Inc. 2005.

In rapidly developing Asian countries, food consumption has drastically expanded and diversified. Trends in Malaysian food consumption are typical of those of developing countries. The overriding objective of this article, therefore, was to explore the structural changes in food consumption expenditure in West Malaysia after the early 1970s when its food consumption diversified under rapid economic growth and urbanization. We have estimated Engel’s expenditure elasticities for food items using aggregated cross-sectional data from the Household Expenditure Survey. Our estimated results clearly indicate that while the expenditure elasticities of away-from-home food, and the elasticities of at-home expenditures for meat, fruits and vegetables, milk and dairy products are relatively high, those of rice and sugar are low. This suggests that the food expenditure structure in West Malaysia has diversified, adding meat, fruits and vegetables, milk and dairy products to the most dominant food item, rice. Moreover, it is likely that the share of food away from home will increase with income enhancement and urbanization due mainly to economic growth.

アジア経済危機下にあって,輸出用農産物を生産している大規模農園(通称エステート)部門が東南アジア経済の不調を緩和したと指摘されている。しかし,こうしたエステート部門のマクロ経済への貢献にもかかわらず,アジア経済危機が個別のエステート経営に及ぼした影響について,具体的な経営データに基づいた議論はほとんど行われていない。そこで本報告では,パーム油などの主要輸出国であるマレーシアを取り上げ,同国のエステート経営を行う企業の会計決算報告に依拠しつつ,アジア経済危機がエステート企業の経営に及ぼした影響を具体的に解明することを主な目的とした。エステート企業の多くは,1980年代半ば以降非エステート事業に参入することによって,経営の多角化を積極的に推進してきた。このことを考慮して,エステート事業と非エステート事業を各々どの程度拡大したかを基準にエステート企業の経営展開を類型化し,経営類型ごとにアジア経済危機の影響を検討した。 得られた知見を要約すると,次のとおりである。 (1)ドル高・リンギ安に伴って,先進国からの輸入依存度が高い投入財の国内価格(リンギ建て)は急騰した。しかし,最大の費用項目であると同時に人手不足によって上昇基調にあった農業労働者賃金は,経済危機による景気低迷もあって安定的に推移した。結果的には,生産コストの上昇よりもリンギ換算した生産物価格のそれが上回ったことから,エステート事業からの利益は大幅に増加した。 (2)エステート経営を行う企業の多くは,1980年代半ば以降,不動産開発などの非エステート事業に参入することによって,経営の多角化を積極的に推進してきた。しかし皮肉にも,企業の思惑とは反対に,アジア経済危機による景気後退の影響を最も被ったのは,経営多角化のために推進された非エステート事業であった。研究対象としたエステート企業の会計決算報告からも,非エステート事業の営業利益が大幅に減少した,あるいは最悪の場合には黒字から赤字に転じたことが確認された。こうした状況下にあって,経済危機下に営業利益の大幅純増を達成したエステート事業が非エステート事業の業績悪化を相殺することによって,景気後退による企業全体の業績悪化を緩和あるいは回避したといえる。

This article explores various factors resulting in temporary migrant workers' decisions to extend their stay in host countries by means of a case study of Bangladeshi factory workers in Malaysia. The employment mediation and passage fees paid to brokers and agents by Bangladeshi workers are very large compared with general living standards in Bangladesh. These large sums are increasing steadily as the number of persons desiring to work overseas increases. Malpractice by brokers and agents causes Bangladeshi workers to overestimate the amount of remittances they can send home, and hence they pay higher mediation and passage fees to brokers or agents. From a humanitarian point of view, the Government should strictly regulate the activities of agents and brokers and provide accurate information to those who plan to work in Malaysia. Statistical analysis suggests that the lower real remittances fall below the expected amounts, and the lower real wages are, compared with passage and mediation fees, the more will Bangladeshi workers wish to extend their stay. These facts imply that if future Bangladeshi migrant workers to Malaysia have the correct information about income levels and living expenses in Malaysia, and hence mediation and passage fees become cheaper, the likelihood of their intending to extend their stays will be much lower.

This article aims to clarify whether social capital has a positive effect on utilization of medical service among poverty stricken slum dwellers in Bangladesh. The statistical analysis, based on the household data obtained from intensive structured survey conducted by the International Food Policy Research Institute and CARE-Bangladesh, clearly suggests that the higher the social capital levels are, the more slum dwellers are likely to get needed medical attention.

It is observed that education has negative impact on agriculture income. For non-farm income, however, it has significantly positive effect. It means that education is relevant with non-farm work in the country. It is cleared from this study that education is necessary for farmers to raise total income. Extension service is also essential for raising farm income.

本研究では,中高生の食行動を規定する要因を解明することを目的とした。主な結論は以下のとおりである。 1)性別や学年などの「個人属性」,「生活習慣・自立性」,「食卓環境・雰囲気」,「家族関係(親との関係)」,「居住地」が中高生の欠食・偏食頻度に影響を及ぼしている。また学年進行に伴って,欠食頻度は増加する一方で偏食傾向は是正される。 2)女子高校生の食行動の乱れを助長している背景要因として,生活習慣の乱れ,友人関係の不安定性,親子関係の不安定性,食卓の雰囲気の悪さが指摘できる。これら4要因の中でも,とくに生活習慣の乱れと友人関係の不安定性が女子高校生の食行動に及ぼす負の影響は大きい。

最近,人的資本や物的資本では把握できない社会的要因として注目を集めている「ソーシャル・キャピタル」(社会関係資本)の概念を援用して,低所得層のフードセキュリティの水準を規定する諸要因を解明することを主たる目的とした。国際食料政策研究所(IFPRI)や世界銀行が実施した大規模標本調査の個票データを用いて計量分析を行った結果,ソーシャル・キャピタルの水準が高い貧困世帯ほど,栄養・食料摂取状況が概して良好であることを指摘した。
:農業経営存続基盤が危機的状況における新たな再生システムについて,その地域の物的人的地域資源の存在とその連携による機能化について地域経営・経済論的分析,ソーシャル・キャピタルの定性定量分析,金融論的分析,歴史的分析により,農業経営の存続のためにその経営効率化とともに林業漁業をはじめ地域他産業との連携システム構築の必要性を指摘した.そのシステムについて地域農業経営体の組織化による集落営農組織および経営外部組織による経営支援サービス組織の提供,地域内の物的人的地域資源利用と機能化に基づいた地域内資源ネットワークシステムの構築について提起した.
わが国農村部に居住する有権者の政治行動を解明するために、調査データの信憑性に定評のある「日本版General Social Surveys 2003年(JGSS-2003)」の個票データを用いて定量分析を行った。地域別に有権者の政党支持について集計した結果、有権者に占める自民党支持者の比率は、農山漁村地域が44%(全国平均は32%)と最も高かった。このことから現在でも、農山漁村地域が自民党の重要な支持基盤であることが確認できる。しかし同地域においても、特定の政党を支持しないあるいは政治に無関心な有権者の比率は41%(全国平均は48%)の水準に達している。またロジットモデルを用いた計量分析の結果、世帯所得が少なく、政治関心度の低い若年・中年男性に無党派層が多いことが明らかとなった。とくに20歳代から40歳代に限ると、これら無党派層は量的に自民党支持者を凌駕している。よって今後、自民党の支持基盤である農山漁村地域においても、無党派層が選挙結果に大きな影響を及ぼす可能性が指摘できる。 つぎに、マレーシア稲作地域における農村調査データを用いて、政権与党による農村政治の支配体制および農村政治における有力者の特徴について分析した。その結果、政府補助金をパトロネージとするポークバレル型の政治支配構造が形成されており、村落開発治安委員会(JKKK)や地域農民組合(PPK、わが国の農協に相当する農業団体)などの農民利益団体が政権与党の支持基盤となっていることを指摘した。また調査対象の6村においては、JKKKの委員長とPPKの組合長の全員が、政権与党の地方支部長であると同時に、農村政治に影響力のあるイスラム寺院(モスク)や簡易礼拝所(スラウ)の責任者をも兼任していた。このような農村政治における有力者は、教育水準が平均的な年配者と、年齢が若いものの高学歴の者に大別できた。今後は、都市部で高等教育を受けた後者のタイプが農村政治の有力者として台頭していくと考えられる。
