Objectives: We used participatory mapping as a tool for empowerment training for promoting health and safety of farmers. We would like to introduce the application of participatory mapping method and report our experiences in a rural community in Korea. Methods: A one-day workshop was offered in six rural villages which were designated as 'safe farm zones'. Each workshop started with an orientation session, followed by a village rounding, presentations of best cases, a group exercise to draw and present a healthy village map. Participants were requested to express their ideas and experiences about healthy and safe residential and working environments on their map. Results: A total of 206 farmers(100 male, 106 female) participated in the workshops. In each workshop, an average of 34.3 farmers participated, and their mean age was 59 years. In the six workshops, the participants proposed a total of 137 action plans. The action plans included improvement of co-working condition, building facilities for recreation, improving traffic safety measures, and improving residential environment. Conclusions: Participatory mapping was successfully developed and applied as a tool for empowering Korean farmers. The participants were able to express their ideas and thoughts about healthy and safe village and action plans on the map. Moreover, some of the actions in the action plans were carried out immediately after workshop.

In order to investigate the offshore wind resources, the "QuikSCAT Level 3" data by the QuikSCAT satellite was analyzed from Jan 2000 to Dec 2008. QuikSCAT satellite is a specialized device for a microwave scatterometer that measures near-surface wind speed and direction under all weather and cloud conditions. Wind speed measured at 10 m above from the sea surface as extrapolated to the hub height by using the power law model. It has been found that the high wind energy prevailing in the south sea and the east sea of the Korean peninsula. From the limitation of seawater depth for piling the tower and archipelagic environment around the south sea, the west and the south-west sea are favorable to construct the large scale wind farm. Wind map and monthly variation of wind speed are investigate at the positions.

The purpose of this paper is to present the environment change of Cheju Island as land development process using GSIS(Geo-Spatial Information System) technique. We implemented the process based on the maps of soil color, underground water pollution points, land use, land development planning and land sight seeing supported by Cheju Province Office. To use the maps for GSIS data, first we transformed the picture data of the office into raster structured picture data using scanner. Second, the coordinate system was added to raster data using 1/50000 geographic map. Third, we estimated land planning process using GSIS technique(overlay and reclass technique). The results showed that land development effected the natural environment(forest, green field, farm land). However, the chemical pollution and land sight seeing was not so much effected by the land development that was found.

Unmanned aerial vehicle (UAV) and sensor technologies are rapidly developing and being usefully utilized for spatial information-based agricultural management and smart agriculture. Until now, there have been many difficulties in obtaining production information in a timely manner for large-scale agriculture on reclaimed land. However, smart agriculture that utilizes sensors, information technology, and UAV technology and can efficiently manage a large amount of farmland with a small number of people is expected to become more common in the near future. In this study, we evaluated the productivity of forage maize grown on reclaimed land using UAV and sensor-based technologies. This study compared the plant height, vegetation cover ratio, fresh biomass, and dry biomass of maize grown on general farmland and reclaimed land in South Korea. A biomass model was constructed based on plant height, cover ratio, and volume-based biomass using UAV-based images and Farm-Map, and related estimates were obtained. The fresh biomass was estimated with a very precise model (R² =0.97, root mean square error [RMSE]=3.18 t/ha, normalized RMSE [nRMSE]=8.08%). The estimated dry biomass had a coefficient of determination of 0.86, an RMSE of 1.51 t/ha, and an nRMSE of 12.61%. The average plant height distribution for each field lot was about 0.91 m for reclaimed land and about 1.89 m for general farmland, which was analyzed to be a difference of about 48%. The average proportion of the maize fraction in each field lot was approximately 65% in reclaimed land and 94% in general farmland, showing a difference of about 29%. The average fresh biomass of each reclaimed land field lot was 10 t/ha, which was about 36% lower than that of general farmland (28.1 t/ha). The average dry biomass in each field lot was about 4.22 t/ha in reclaimed land and about 8 t/ha in general farmland, with the reclaimed land having approximately 53% of the dry biomass of the general farmland. Based on these results, UAV and sensor-based images confirmed that it is possible to accurately analyze agricultural information and crop growth conditions in a large area. It is expected that the technology and methods used in this study will be useful for implementing field-smart agriculture in large reclaimed areas.

급속한 도시화는 환경 생태적 훼손과 난개발, 사회 경제적 문제를 야기시키고 있다. 도시화에 따른 문제 해결과 친환경적이고 효율적인 국토개발을 위해서는 도시성장 현황과 특성을 파악하고, 이를 반영하여 정책을 수립하는 것이 중요하다. 본 연구는 기존의 지역단위가 아닌 우리나라 전체를 대상으로 도시성장에 대한 지난 20년간의 현황과 특성을 분석하여 도시정책을 수립함에 있어 기초자료로 활용하고자 한다. 이를 위해 환경부에서 제작한 1980년대, 2000년대 토지피복지도를 이용하여 도시지역을 추출한 후 GIS와 통계적 기법을 이용하여 행정구역 위계별 도시성장 패턴분석을 실시하였다. 그 결과, 1980년대 이후 개발지역 면적이 1980년대 이전 대비 2.5배 확대되었으며 특히, 수도권인근농촌은 21.2배가 증가하였다. 특별시와 광역시는 고도가 낮고, 간선도로와 주요 도심과 가깝고, 도로율이 높고, 환경 생태적 및 법제적 제한이 있는 지역에 개발되었으며, 산림과 초지에서 도시적 토지로 전용되었다. 반면, 대도시인근농촌, 수도권인근농촌, 지방농촌은 고도가 높고, 간선도로와 주요 도심과 멀고, 도로율이 낮으며, 환경 생태적 및 법제적 제한이 없는 지역에 개발되었으며, 농지에서 도시적 토지로 전용되었다. 즉, 대도시를 중심으로 한 도시성장이 팽창함에 따라 가용토지의 부족 및 각종 규제와 정책으로 도시 외곽지역에서 불리한 지형적 조건에도 불구하고 도시개발이 활발이 이루어졌음을 알 수 있다.
