The objectives of this study were to assess implementation on tariff quotas and tariff cuts committed in the WTO as result of Uruguay Round(UR) negotiations and to examine impacts of reductions in agricultural protection agreed in the UR on major non-timber forest products markets. The implementation of WTO Agreement on Agriculture was analysed based on the relevant data and statistics. The impacts of implementation on tariff cuts and tariff quotas on non-timber forest products markets were estimated by using supply and demand elasticities from previous studies and data on production, consumption and trade after UR. The quantities of Chestnut, Pine nut and Jujube imported by the system of tariff quota did not exceed the committed quotas over the five years from 1995 to 1999. The current level of applied rates on imports of non-timber products is much lower than that of bound rates, which will be maintained until the year 2004. It is estimated that increase in imports after UR reduced prices and that reduction in prices led to decrease in expenditure and to increase in consumer surplus. It is estimated, however, that production level significantly decreased due to rise in imports and that the negative effects on production exceeded positive effects on consumption. Exports of most non-timber forest products decreased after UR even though non-timber forest products could gain access to the export markets at the lower tariffs as a result of UR.

This study applied the portfolio approach as a means to provide decision-making information for the establishment of the optimal production plan for non-timber products. The target items of non-timber forest product were Chestnut, Jujube, Walnut and Astringent Persimmon. The data used in this study were the annual report of forestry production cost survey which contains the annual production, annual gross income, and annual product cost from 2008 to 2013. These data were used to calculate the expected return of non-timber forest product. The objective function in the portfolio models was to minimize the expected return volatility, called risk and the constrain was to achieve the minimum expected return rate. Results indicated that the production ratio of the nuts and fruits in 2013 was 7% for Chestnut, 20% for Jujube, 5% for Walnut and 68% for Astringent Persimmon. Furthermore, portfolio presented that the production ratio was 10% for Chestnut, 9% for Jujube, 3% for Walnut and 78% for Astringent Persimmon in the near future. The cause was analyzed due to maintain stable production and income of Astringent Persimmon and Chestnut. Meanwhile, the revenue of Walnuts and Jujube was in great variation with relatively higher revenues.

Wood store carbon that the forest absorbed until burned or decomposed over a long period. Such materials are most used in houses except in paper and pulp, and the use of wood in houses play an important role in reducing green-house gases. Therefore, we estimated the amount of carbon stocks in Korean houses, and analyzed how much contribution such stocks offers to green-house gas reduction. As the result, the carbon stocks amount of the wood products in Korean houses was 28.4 million tCO2, which is 4.6% of the total annual green-house gas emission in Korea (620 million tCO2 e), and 77.4% of forest sinks (LULUCF). Even though few wooden houses which use most wood in housing exist in Korea, the carbon stocks of wood products in houses in 2010 increased to 4.1 times that in 1975 (21.4 million tCO2) because the carbon stocks increased due to apartment construction, which hit its stride from the last 1980`s.

2006 IPCC 가이드라인에서 제안한 HWP 탄소계정 방법을 이용하여 HWP 내 탄소 저장량을 추정하였고 우리나라 국가 온실가스 인벤토리와 산림 부문에 미칠 영향을 분석하였다. 사용 중에 있는 제재목, 목질보드류, 기타산업용 목재, 종이 및 판지를 대상으로 하여 목제품 내 탄소저장량의 변화량을 추정하였다 1970년부터 2008년 동안 사용 중에 있는 목제풍 내 이산화탄소 저장량의 연간 변화량은 접근법에 따라 -9.023Gg CO2/yr에서 4,052Gg CO2/yr으로 추정되었다. 우리나라는 목제품의 순수입국이기 때문에 탄소 축적 변화 접근법이 가장 유리한 결과를 보였다. 그러나 각 접근법이 목체품의 벌채량 및 교역량. 바이오에너지로의 목재 이용과 재활용에 미치는 영향은 상이하게 나타나고 있다. 따라서 계정 방법에 대한 우리나라 입장을 결정할 때 국가 온실가스 인벤토 리에 대한 영향뿐 아니라 미래에 추진할 산림정책 방향도 고려하여 야기될 수 있는 부정적인 영향을 최소화하는 방법을 선택해야 한다. This study estimated the amount of carbon stocks in harvest d wood products (HWP) using accounting approaches suggested by 2006 wee guidelines and analyzed the impacts of different approaches on national greenhouse gas inventory and the forest sector in Korea. The change in carbon stocks was calculated at the level of semi-finish d wood products, which cover sawnwood, wood-based panels, other industrial wood, paper and paperboard. An estimation of the changes in carbon stocks in HWP in use for the period 1970-2008 varied between -9,073Gg CO2/yr and 4052Gg CO2/yr depending on the accounting approach used. The stock-change approach provided the most favorable results because Korea was a net importer of wood products. However, each approach generates different impacts on harvest, trade, the use of wood for energy production and recycling. When deciding its position on accounting approach, thus the Government should consider future direction of national forest policies as well as the effect on national greenhouse gas inventory for the minimization of negative impacts resulting from its selection.
