This study aims to identify feasible policy direction of the 6th industrialization in agriculture based on the current agricultural and rural environment in Korea. To do so, this study employes a heckman selection model to correct a probable selection bias, utilizing the Korean agricultural census in 2010 and the agricultural statistics of farm enterprises in 2011. This study focuses on the differences of the farm and off-farm income determinants, according to conjoint types of the 6th industrialization such as Type 1 (primary+secondary+tertiary) vs. Type 2 (primary+secondary or primary+tertiary). The empirical results show Type 2 has much higher possibilities to earn farm and off-farm income in Korea, especially for farm enterprises. This study concludes with providing some policy implications reflecting rural and agricultural environment in Korea.

The public value of agriculture and rural areas is closely associated with the concept of multifunctionality of agriculture and rural areas, which in turn signifies economic values other than the production function of agriculture and rural areas. Based on the survey results, virtual scenarios were set up and the contingent valuation method (CVM) was used to estimate the amount consumers are willing to pay (WTP) for the public functions of agriculture and rural areas. This study selected five domains of the public value (environment conservation, maintenance of landscape and cultural tradition, enhancement of national prestige, local community maintenance and socio-economic functions, and food security) and 21 value items as components of the public value. An economic assessment of the public value of agriculture and rural areas was conducted using a binomial logistic regression model. The estimation results showed that the public value consumers are willing to pay ranges from a minimum of 6,346.8 billion won to a maximum of 9,327.2 billion won.

Agriculture is not only sources, but also sinks of GHGs through removal or sequestration of carbon and methane. Therehave been many efforts around the world to improve agriculture’s ability to sequester GHGs and to seek ways for economicbenefits through the emissions reduction project. Specially, animal waste management system and biogas plants have beenuseful to environmental policies in agriculture sector. The objectives of this study were to analyze the CDM project currentsituation in agriculture sector and draw a implications from its analysis. As a result of the investigation, strategies andprocedures are suggested to link agricultural policies to the CDM projects to create economics opportunities for the koreanagriculture. So it will be useful, a strategy to raise the economic feasibility of a rural area’s animal waste managementsystem and biogas plant project should consider to develop domestic technologies of biogas digester.
