<p>The purpose of this study was to clarify the current and future status of farmland consolidation for rice paddy field farms, using the case of "canyon-type hilly and mountainous areas." In the study area, small-sized paddy fields expand across long and narrow areas along mountain streams and straddle many water systems, given the expanded scale of farming. Because of the farmers' increasing burdens for water management and weeding on the ridges between paddy fields, there is a limit to the scale expansion by debt. On the other hand, if the farmers specialize in the consignment of machine operation, an operation on a scale of 20–30 ha is possible, and high income can be expected. It is desired to organize residents who can weed on the ridge and manage water by utilizing subsidies so that core farmers can specialize in machine operation.</p>

わが国の柑橘作は，1970年代半ば以降，供給過剰によるみかん価格の暴落や産地間競争の激化などを背景に，縮小期に入ったといわれている。さらに平成以降は，「みかん農業縮小の第2プロセス」と表現されるように，担い手の高齢化・後継者不足が進行し，柑橘作をリタイア・縮小する農家が増え，産地の崩壊が懸念されている。このような状況の中で，産地を維持するためには，離農もしくは経営を縮小する農家が手放す樹園地を，適切な担い手に流動化できるかが鍵になるといえる。

わが国の柑橘作では，商品性(外観，品質)を高める観点から，化学合成農薬を多用することによって，病虫害を抑える方法が採られており，慣行栽培では一般に，年間10回前後におよぶ化学合成農薬の散布が行われている。一方で，「食の安全・安心」に対する消費者ニーズの高まりや，行政による諸制度の整備を背景として，近年，柑橘作においても，環境保全型栽培に取り組む生産者が増えつつある。しかしながら，柑橘作は病虫害の種類が多く，環境保全型栽培を実施する場合，病虫害対策に多くの困難が伴うと考えられる。本稿の課題は，経済的・技術的な視点から，環境保全型柑橘作における無農薬栽培の成立可能性を明らかにすることである。

Irrigation plays a significant role in the path of agriculture development with its consequent effect on the progress and livelihood of agrarian-based society like Nepal. Majority of the irrigated areas are served under Farmer Managed Irrigation System (FMIS). This study is carried out to determine the socio-economic, demographic factors influencing satisfaction of the users in the Kumroj Farmer Managed Irrigation System (KFMIS) regarding water availability in plain area of Nepal, using the farm household survey data collected from 100 beneficiaries. Variation is apparent among the water users regarding several socio-economic and demographic characteristics. The logit model is used to analyze the relationship between dichotomous relations of satisfaction level (satisfied/dissatisfied) with the irrigation system by the help of certain independent variables. The result shows that the variables such as water availability on time, location of farm, land size, education in terms of schooling years and rice productivity significantly influenced the satisfaction of the system beneficiaries in the study area. It is further suggested that water distribution system should be upgraded in view of the water availability, farm location and size of the farm to improve users' satisfaction for the effective management of FMIS in the long run.

The purpose of this paper is to grasp the level of satisfaction by inhabitants for the agricultural water use facilities, and clarify the direction of improvement. To approach the above subject, the authors sent questionnaires to inhabitants in Minamiumemoto, Takai and Nakano district in Dogo plain, Ehime prefecture during December, 2004 and performed CS portfolio analysis as an evaluation technique. The items of research are the satisfaction for agricultural water use facilities, "Natural environment", "Scene", "Management", "Sense of closeness", "Water quality", "General satisfaction", and the concern for agricultural water use facilities. The results of this study are as follows: (1) As a result of having researched concern and satisfaction by inhabitants for the agricultural water use facilities, the level of concern in Minamiumemoto district is low in comparison with other two districts, and the level of satisfaction in Nakano district is low. On the other hand, in Takai district where environmental maintenance of the waterside is performed positively, the level of both two items is high in comparison with other two districts. (2) As a result of CS portfolio analysis, it is clarified that "Water quality" shows the improvement point in three districts. But the background of this is different in every district, and different methods are necessary for the measures. (3) Satisfactory structure is different for the other four items in every district. In Minamiumemoto district, items except "Water quality" is evaluated in some degree, particularly "Sense of closeness" shows the superiority point. In Takai district, "Sense of closeness" shows the precaution point, "Natural environment" and "Scene" shows the improvement point, for the consciousness for environment is high in comparison with other districts. In Nakano district, "Management" shows the precaution point, and this reflects dissatisfaction for the present conditions of the management system of agricultural water use facilities.

This study was carried out to analyze the cost efficiency of maize production in the Chitwan district, Nepal with a view to predict economic efficiencies using stochastic frontier cost function. The primary data were collected from 180 maize farmers representing 12 village development committees (VDCs) including one municipality of the district during May-June 2005 for the cropping year 2004-2005. Among various factors, use of manure accounted the highest share in the production cost followed by labour and tractor costs. The maximum-likelihood (ML) estimates of the parameters revealed that estimated coefficients of cost of tractor, animal power, labour, fertilizer, manure, seed and maize output gave positive coefficients and were significant at 5% level. Further, quantitative estimates obtained from the cost function shows the mean cost efficiency of 1.634 indicating that an average maize farms from the study incurred about 63% costs above the frontier cost-an indication of inefficiency. Also, the significant years of schooling of the household head and maize area in the inefficiency model indicated the positive effect of these factors on cost efficiency of the farms. From the analysis of scale effect among maize farms, it was revealed that the maize farms experienced an increasing return to scale, that is, the output increased more proportionately than the total production cost.

This study was carried out during April-May, 2005 to explore the management and operation of the Kumroj FMIS, one of the Farmer Managed Irrigation Systems operating (FMIS) in three village development committees (VDCs) of the eastern Chitwan district, Nepal. The Kumroj FMIS committee is responsible for the operational and managerial affairs of the system while the East Rapti Water Users Association is the apex body that provides major/external financial help for this system including all the FMISs in that area. This system delivers service to the beneficiaries on an unbiased and transparent manner. The rights, rules, and duties related to operation and management are entirely under the control of the water users themselves. In this system, water in each branch canal is allocated depending upon the area and type of land to be irrigated as well as the season. The irregular water supply resulting from the unlined canals is the major constraint encountered in the effective service delivery of this system. Further, the tail users receive less of the irrigation water as compared to the head users. The practice of labor mobilization based on households utilizes little technology. Proper repair and maintenance as well as canal improvement work is of utmost important to reduce the conveyance loss. The administrative work, especially communication, is heavily dependent on Panipale (water guards), hindering the smooth operation of system. Therefore, restructuring the administrative framework as well as improving the canals is of utmost importance for the sustainable and effective functioning of Kumroj FMIS.

Irrigation has played a contributing role in enhancing agricultural production and productivity in Nepal. Farmer-Managed Irrigation Systems (FMIS) have been operating for more than 25years using local capacities. A survey was accomplished during April-May, 2005 to evaluate the changes that have been brought about by the introduction of FMIS at Kumroj in Chitwan district. The changes in crop species, cropping area, irrigated area, crop production, productivity and cropping intensity after the introduction of FMIS were explored. Comparisons were made in between farmers participating and not participating in FMIS. There was a total increase of about 47% in irrigated land since the introduction of FMIS. This has helped increase crop production as crops can be grown more than once a year and as a result cropping intensity has been tremendously improved to more than 256 percent. Further, the cropping areas as well as the crop productivity have been greatly influence with the inception of FMIS. The change in the cropping pattern from cash crop oriented to food crop production to combat food insufficiency in Nepal. Considering the successes of FMIS, development of small-scale farmers managed irrigation system to improve agricultural production in Nepal should be emphasized.

The purpose of this paper is to clarify the formation processes of grassland in dairy farming in post-war cultivated high-land dynamically, paying attention to decision-making by the leader of farmers, based on the case study in 0 village, Seiyo city Ehime prefecture. To achieve above-mentioned purpose, firstly, I grasped social and economic trend in 0 village before the war, and clarified the factors which affect the formation of grassland after the war. Secondly, I divided the formation processes of grassland after the war into four periods;(1)the period of trial crops (1946 -58),(2) the early years of introduction of dairy farming (1959-69), (3) the period of enlargement of grassland (1970-82), (4) the period of completion of grassland infrastructure(after 1983),and clarified the characteristic of grassland utilization in each period. Now, in 0 village ,high rate of self-sufficiency in fodder is realized by many-sided utilization of the three types of grasslands ( grassland owned by individual farmer, grassland owned by village, grassland cultivated by government). And the stable grassland infrastructure in 0 village have been formed by the geographical and historical conditions peculiar to high-land, the various political supports after the war, and the ability of leaders who accept the political supports positively and enlighten farmers.
