This study is aiming at identifying the foreward and backward lingkage effects of the farm land base development project. Korean Government has continuously carried out farmland base development projets including the integrated agricultural development projects. large and medium scale irrigation projects and the comprehensive development of the four big river basin including tidal land reclamation and estuary dam construction for the all weather farming since 1962. the starting year of the five year economic development plans. Consequently the irrigation rate of paddy fields in Korea reached to 75% in 1998 and to escalate the irrigation rate, the Government had procured heavy investment fund from IBRD. IMF and OECF etc. To cope with the agricultural problems like trade liberalization in accordance with WTO policy, the government has tried to solve such problems as new farmland base development policy, preservation of the farmland and expansion of farmland to meet self-sufficiency of foods in the future. Especially, farmland base development projects have been challanged to environmental and ecological problems in evaluating economic benefits and costs where the value of non-market goods have not been included in those. Up to data, in evaluating benefits and costs of the projects, farmland base development projects have been confined to direct incremental value of farm products and it's related costs. Therefore the projects'efficiency as a decision making criteria has shown the low level of economic efficiencies. In estimating economic efficiencies including Leontiefs input-output analysis of the projects could not be founded in Korea at present. Accordingly this study is aimed at achieving and identifying the following objectives. (1) To identify the problems related to the financial supports of the Government in implementing the proposed projects. (2) To estimated backward and foreward linkage effects of the proposed project from the view point of national economy as a whole. To achieve the objectives, Hwangrak benefited area with reservoir which is located in Seosan-haemi Disticts, Chungnam Province were selected as a case study. The main results of the study are summarized as follows : a. The present value of investment and O & M cost were amounted to 3,510million won and the present value of the value added in related industries was estimated at 5.913million won for the period of economic life of 70 years. b. The total discounted value of farm products in the concerned industries derived by the project was estimated at 10,495million won and the foreward and backward linkage effects of the project were amounted to 6,760 and 5,126million won respectively. c. The total number of employment opportunities derived from the related industries for the period of project life were 3,136 man/year. d. Farmland base development projects were showed that the backward linkage effects estimated by index of the sensitivity dispersion were larger than the forward linkage effect estimated by index of the power of dispersion. On the other hand, the forward linkage effect of rice production value during project life was larger than the backward linkage effect e. The rate of creation of new job opportunity by means of implementing civil engineering works were shown high in itself rather than any other fields. and the linkage effects of production of the project investment were mainly derived from the metal and non-metal fields. f. According to the industrial linkage effect analysis, farmland base development projects were identified economically feasible from the view point of national economy as a whole even though the economic efficiencies of the project was outstandingly decreased owing to delaying construction period and increasing project costs.

Rice is not only main food but also key farm income source of Korean farmers. In spite of the above facts, rice productivity was decreased on account of drought in every 2 or 3 years interval owing to the vulnerability of irrigation facilities throughout Korea in the past decades. As an context of the first five year economic development plan, all weather farming programme including 4 big river basin comprehensive development projects and large and medium sized irrigation water development projects were carried out successfully. Therefore the area of irrigated paddy were increased from 58% in 1970 to 76.2% in 1999. In the past decades, the Government had invested heavy financial funds to develop irrigation water but as an factor share analysis, the contribution rates of irrigation water and investment for farmland base development project have not been identified yet in national agricultural economic level. It is very scarce to find out the papers concerned to macro-economic factor share analysis or contribution rates of water and investment cost to rice production value in Korea considering the production function of the quantity of irrigation water and investment cost as independent variables. Accordingly this paper covered and aimed at identifying (1) derivation of rice production function with the time serial data from 1965 to 1999 and the contribution rates of irrigation water and total investment cost for farmland base development project. The analytical model of the contribution rates was adapted the famous Cobb-Douglass production function. According to the model analysis, the contribution rate of irrigation water to rice production in Korea was shown 37.8% which was equivalent to 0.28 of the production elasticity of water. The contribution rate of farmland base development project cost was revealed 22% and direct production cost of rice was contributed 60% in the growth of rice production and farm mechanization costs contributed to 18% of it respectively. The two contribution rates comparing with the direct production cost were small but without irrigation water and farmland base development, application of high-pay off inputs and farm mechanization might be impossible. Considering the food security and to cope with the frequent drought, rice farming and investment for the irrigation water development should be continued even in WTO system.

급격한 토지이용의 변화가 진행되고 있는 수도권 인근의 고양시, 남양주시, 용인시를 대상으로 고해상도 영상과 수치지도를 활용하여 논, 밭, 시설재배지, 과수원의 면적과 형상, 이용 현황을 파악하기 위한 농경지 지도를 작성하여 기존 수치지도와 비교한 결과 기존 수치지도에 비해 농경지의 이용 현황을 보다 세부적으로 정확하게 분류할 수 있었다. 또한, 농경지 지도와 수치 지적도의 농경지 부분을 중첩하여 '07년 토지이용도로 갱신하고 '99년에 작성된 토지이용도와 비교한 결과 3개 시 모두 조사기간 동안 논 면적이 3,000~5,000 ha 정도 크게 감소한 것으로 나타났으며, 밭과 과수원도 논과 함께 주거지로 전용되면서 감소하는 추세였다. 그러나 집약적인 재배가 가능하여 고소득이 기대되고 다른 지목으로 변경이 용이한 시설재배지의 경우에는 면적이 비슷하거나 증가한 경향을 보였다. 향후 고해상도 영상을 활용한 농경지 지도의 확대 구축과 이를 활용한 토지이용도 제작은 토양 조사 등 각종 조사 사업의 최신 자료로 활용 될 수 있을 뿐 아니라, 정확한 경지면적 산출을 통해 농업통계 및 농업정책 자료로써 효율적인 경지관리에 활용될 수 있을 것으로 판단된다.

본 연구에서는 농어촌지역 발전을 위해 공공사업을 수행하고 있는 한국농어촌공사의 사회적 가치 증진 방안을 모색하였다. 이를 위해 본 연구에서는 한국농어촌공사 사업의 최종 수요자인 외부 이해관계자 중에서 농업인들을 대상으로 KRC 사업 참여 실태 및 사회적 가치 인지 여부 등을 살펴보았다. 그리고 네트워크 분석을 통해 외부이해관계자들이 참여하고 있는 한국농어촌공사 사업의 주요 특징과 중요 사업을 도출하였다. 네트워크 분석을 한 결과, KRC 사업 중에서 대부분 지역에서 농어촌용수관리사업이 가장 중요한 사업으로 나타났다(농어촌용수관리사업 0.805, 농업생산기반정비사업 0.758, 농지은행사업 0.762, 지역개발사업 0.643). 반면 제주도의 경우에는 지역 특성상 농업생산기반정비사업과 지역개발사업이 중요한 사업으로 분석되었다. 이러한 분석결과, 한국농어촌공사 사업은 지역별로 각 사업간 연결 중앙성(degree centrality) 값이 다르므로, 지역 여건에 맞는 한국농어촌공사 사회적 가치 증진 노력이 필요하다. 이를 위해 "사회적 가치 플랫폼"을 구축해 대내외 모든 이해관계자들이 자유롭게 한국농어촌공사 사업에 참여하는 방안을 모색하는 것도 한 방안이 될 수 있을 것이다. 이를 통해 한국농어촌공사의 사회적 가치도 증진될 것이다.
