Climate change has effects that manifest via changes in temperature, rainfall pattern, and its predictability. These changes have deleterious effects on farmers via yield reduction. To this end, several approaches have been employed to overcome problems with climate change. Adoption of climate-smart agriculture (CSA) is one of the most resilient solutions. It is among the most promising solutions to climate change problems. This study evaluates the factors that influence farmers’ adoption of CSA and the consequent impact of adoption on farm production. The multinomial logit model and the Heckman two-step model were used to identify CSA adoption determinants and to evaluate CSA adoption effect on yield, respectively, using 150 farms. Access to extension service, cooperative membership, and land size per family member are the major drivers of CSA adoption. Land size and credit facility source are the major factors affecting farm crop yield. The inverse mills ratio while positive, was not statistically significant, but suggests that adoption of CSA by farmers did not influence farm output.

Pork is a popular meat consumed in Korea. However, the consumption pattern has typically focused on preferred parts, like pork belly, which is usually broiled. This consumption pattern has increased both stocks of low fat parts and medical costs, and has thereby disturbed pork industry growth and the national health welfare. Changing the consumption patterns of preferred parts and encouraging consumption of low fat parts will improve consumers’ quality of life and also increase their benefits. Thus, this study estimated WTP (Willingness To Pay) for health funds among consumers who eat pork meat, considering the health benefits gained by consuming low fat parts and changes in preferred part consumption. The results of this study show that WTP is higher when consumers have a smaller family and a higher income; these consumers plan to increase intake of pork meat in the future and think that the promotion of low fat pork meat consumption is more important. The WTP for health funds is estimated to be 49won to 287won through Logit Model. The health benefits of low fat consumption were estimated to be 92 billion won to 539 billion won per year. Therefore, reforming low fat pork consumption not only changes the traditional consumption pattern focused on preferred parts but also leads to a variety of benefits for consumers, including health benefits.

The purpose of this research is to estimate the conservation values of Jeju groundwater by using the double bounded contingent valuation (DBCV) method, which is one of main methodologies to tackle non-use values of public goods. Jeju groundwater has been at the center of dispute over its development and conservation in recent years. The Samdasoo company, which extracts groundwater from Jeju Island and which occupies over 40% market share of the domestic water market, has a plan to expand the amount of groundwater extraction, while the conservation side continuously points out that the conservation value of Jeju groundwater is also as important as its market value now. With respect to this issue, the Dong-seo Research Group conducted a face-to-face survey (DBCV questionnaire) of 600 Jeju residents from July 13 to August 5, 2010. The result of the one-off conservation fund payment mechanism applied here found that the amount of additional WTP is ₩11,023 on average per household. The expanded total conservation benefit to all 219,771 households in Jeju is about ₩2.4billion. The result shows that ₩11,023 of WTP is at the equivalent level to its use value, the monthly tap water cost of ₩12,530 per household in 2008, and that the benefit of conserving groundwater in Jeju is no less than the present market value.
