  • Indicators of environmental conditions qualitatively and quantitatively describe the state of the environment and natural resources, and the OECD (Organization for Economic Cooperation and Development) has initiated and suggested AEIs (Agri-Environmental Indicators) to assess trends over time of the effects of agriculture on the environment and the effectiveness and efficiency of agricultural and environmental policy measures since 1990's. This study aims to develop the state indicators of water quality for agricultural water, surface and groundwater, to evaluate the environmental impacts of agricultural activities and policies by qualifying the environmental levels of a nation. Status indicators were calculated according to the agricultural water quality standards of OECD and Korea, and their trends were analyzed over time. Particularly, nitrate ($NO_3{^-}$) status indicators of ground water in 2013 were significantly lower than the ones in 2000. Overall, the water quality indicators of surface water in 2013 were higher than the ones in 2012, except for pH and DO. The groundwater quality indicators in 2013 were lower than those of previous years. The optimal management indicators were calculated to assess agricultural surface water and groundwater quality. The findings of this study indicated that the state indicators could play a significant role to establish policies and procedures for managing and conserving water resources. This study also discussed water pollution caused by agricultural and industrial effluents.

  • This study intended to compare rural development programs between China and Thailand, focused on research and extension activities. In China, Agricultural Science Administration(ASC) took charges in agricultural research, and under the ASC there were 39 agricultural organizations throughout the country. There were distinctive differences as to condition of agricultural areas, under-developed area at middle and developing area by sea and river. To improve agricultural production in China, diffusion of new agricultural technology would be important along with supplying equipment such as soil test kits, plant nutrition analysis sets and vehcles for extension educators. In Thailand, under the Ministry of Agriculture & Cooperatives, there were five departments, seven divisions and eight national enterprises. Among them, Department of Agriculture was in charge of agricultural research while the Department of Agricultural Extension for extension services. Each department had sub-division and provincial organization including personnel management and budget. However, the relationships and consistency between the Department of Agriculture and the Department of Agricultural Extension needed to be improved for better cooperation of research and extension.
