  • It is to show the problems of the existing techniques to estimate agricultural water demand and to suggest the new methods considering the water demand for non-irrigated area and decrease of water loss in canal. It is to suggest the methods to improve the techniques for estimating agricultural water demand and to analyze the water demand and supply according to the facilities capacity. Until now, the concept of per the unit used to estimate agriculture water demand is useful to estimate demand, but is insufficient to cope with the variations of conditions in future. And the paddy area of government is not realistic against a trend of decrease. Water demand decrease is caused by constructions of irrigation facilities as constructing of irrigation canal, but application loss ratio is fixed. Increase of the water demand owing to the increase of the yield per the unit area is also the actual condition which is not considered. The guide-line must contain these contents for a demand estimate.

  • Uiryung Watershed area, located at the confluence of Nam River and Nagdong River has 9000 ha of agricultural land area and 3024 ha of paddy rice field have been reclaimed and managed by Korean Agricultural and Rural Infrastructure Corporation(KARICO) in the riparian area since 1954. In spite of irrigation and drainage improvement projects in last 3 decades since 1970, there are severe drought and innundation problems in the area. To improve the difficulties and efficient usage of irrigation water not only for agriculture but also for environmental conservation and cultural ceremony, Automatic Water management system has been installed supported by Ministry of Agriculture and Fishery in Korean Government. The control office in Uiryung Branch Office of KARICO, receive all the water management records from Remote Terminal Units in 7 reservoirs and 26 Pump stations to operate the decision supporting system of irrigation and drainage facility during cropping period. Since the completion of the water management system at the end of 2003, the electric cost decrease in 80 % than average years. In spite of decrease of two technical assistants since 2004, complains from farmers for the water management are very rare. The technological experience from the automatic water management system would contribute not only for the efficient water management of Uiryang area but also for the modernization of water management of other watershed areas in the future.

  • This study provides a physical indicator of landscape that can be guidelines so as to evaluate landscape agricultural region for visual landscape planning, finds out the guideline for visual landscape planning lastly through examining importance of indicators and the preference of each indicator of landscape. The physical landscape indicators were derived from document study and questionnaire survey to evaluate visual landscape on landscape agricultural region. In addition, field study was conducted to examine and inspect the physical landscape indicator, managers' interview and photograph was took for evaluating the landscape simulation. Moreover, the important elements for visual landscape planning of landscape agricultural region, the importance of physical landscape indicator and the preferences of each indicator were derived by conducting questionnaire to experts and general publics. The physical landscape indicator guideline was established from the following procedures. In case of the land, flat area had higher preference than steep region. So, planning an agricultural area at a flat region with open space will be better than establishing an agricultural area on a steep region. In case of the kind of landscape crops, For the background of landscape agricultural region, the seashore type had the highest preference and mountain type and non-background type was followed in order. According to the study, facilities built with natural elements such as straw-roofed pavilion received high preference. Therefore, look-out shed and straw-roofed pavilion should be introduced in the landscape agriculture planning to select materials and colors to keep harmony with the nature. The result of this study could be used as a best choice for improving visual landscape of landscape agricultural region on selecting suitable land, facilities and so on. Moreover, the results of manager interview could be used as a useful tool in the management and formation of visual landscape. The landscape point evaluating visual landscape of landscape agricultural region could be used as a reference for establishing relative guideline for the direct payment program for rural landscape conservation and landscape agreement. In addition, it could be a useful reference to improve the general landscape and revitalize the rural area.

  • Along with global warming, ever intensifying weather events have increased damages to agricultural farms and facilities. The objective of this study was to investigate the spatial distribution and regional characteristics of agricultural damages by extreme weather events. Agricultural disaster statistics provided by the National Emergency Management Agency were summed over for a 13-year period from 1998 to 2010 and used for the spatial analysis. Two indices of damage area ration and property damage per unit area were introduced to quantify regional agricultural damages. As the results, farm inundation accounted for the largest area primarily damaged by typhoons with heavy rainfalls. Most property damages to farm lands originated from farm erosion in the alpine regions by localized guerrilla rains. The two major causes of damages to greenhouse and livestock facilities were typhoon with strong wind and winter blizzards. Gangwon was the province of the largest property loss mostly from farm land erosion losses, followed by Gyeongnam, Jeonnam, and Chungnam where losses to greenhouse and livestock facilities were relatively greater. Property loss per unit area was also the greatest for the Gangwon province (4.91 M\/ha), followed by Gyongnam and Chungnam of 2.20 and 1.50 M\/ha, respectively. Unit loss for greenhouse and livestock facilities was 13.3 M\/ha, approximately 13 times greater than that for farm land (1.06 M\/ha). The study findings indicated the importance of reducing highland farm erosion and reinforcing farming facilities structures for agricultural disaster management.

  • This study was conducted to estimate the water quality of agricultural groundwater well located in Buan-gun, Jinan-gun, Sunchang-gun, and Jangsu-gun of Jeollabuk-do. The groundwater samples were collected at 328 sites (Buan-gun: 158, Jansu-gun: 45, Sunchang-gun: 32, Jinan-gun: 93, respectively). We measured 4 kinds of general contaminants (pH, $NO_3-N$, $Cl^-$, and COD) and 10 kinds of specific contaminants (Cd, As, $CN^-$, Hg, phenol, Pb, $Cr^{+6}$, organophosphorus, trichloroethylene, and tetrachloroethylene). Generally, the level of general contaminants and specific contaminants in the agricultural groundwater was suitable for water quality standard in all sites for agricultural irrigation water. Exceptionally, chloride concentrations were exceeded water quality standard of agricultural groundwater at some sites in western coast area of Jeollabuk-do. Although water quality standards in agricultural groundwater have been suitable, the water contaminants of agricultural groundwater in western coast area were gradually increased than eastern mountain area.

  • To strengthen the competitiveness of agricultural sector of the Korea, the direction of market trends on agriculture of the Malaysia was reviewed. The most dominating agricultural area in value is palm oil products, and forest products, sea products poultry products and rubber products is in order. The cultivated area of highest two top plants, oil palm and rubber, was about 4.4 million hectares in 2005, but it is decreasing year by year. Comparatively, rice field, pine apple and fruits tree cultivating area is increasing in tendency by the year. Among all the agricultural products, those items such as pork meat, poultry, egg were self-sufficient, rice, fruits, vegetables and sea products were about 70 to 80% self-sufficient, and beef meat, goat meat and milk were below 20% self-sufficient. Most of the grains, such as wheat, rice, barley, corn etc. and their processed food were imported. Also, temperate fruits such as apple, pear, and water cultivated as well as sprouting vegetables are imported. Ornamental products as cutting flowers and orchids are exported to mainly to the Singapore, but high quality temperate fruits and vegetables are imported from Australia. Oil palm exportation covers the balance of the other items imported and obtaining the foreign money as well in Malaysia.

  • The purpose of this paper is to find out and discuss methods of development applicable in rural agricultural area. It is expected that rural economy will decrease in the future because of the structural problems of agricultural economy itself. The demands of rural communities for an improvement in the living standards should continue to increase but the present living environments remain poor and are at a relatively low level. This investigation focuses on the analysis of development types in rural areas in Japan. Various methods of development must be used considering specific features of each rural village. The village people's participation must be needed for success of certain methods of development. An example is the type of greentourism and type of exchange between the urban and the rural areas. Other types of development require enormous expense for construction of facilities. Various strategies and methods of development are needed in rural agricutural area in Korea. The simple method of development that is widely used currently is not really helpful to the development of rural agricultural economy.
