Of the countries where Korea has advanced for overseas afforestation investments, Indonesia might be the most important country. As the end of 2010, nine Korean companies have been implementing afforestation projects in Indonesia, covering a total area of one hundred and fifty thousand hectares roughly. Following the Memorandum Of Understanding (MOU) on afforestation investment covering five hundred thousand hectares (A/R CDM / industrial afforestation) signed between Korea and Indonesia, the two countries concluded in 2009 an additional MOU covering two hundred thousand hectares for biomass afforestation, thus securing a total afforestation area of seven hundred thousand hectares. Further it was guaranteed that afforestation license would have validity for maximum 95 years, which laid the foundation for long-term stable investments for afforestation projects. Forest law of Indonesia consists of Presidential decree and Governmental decree as superior regulations and Minister's decree as subordinate regulations, being made up of total 17 chapters. Forestry Minister's decree was amended at end of last year, as regards license for exploitation of timber and forestry products in afforestation area. In the past, such license to develop and use timber and forestry products had been granted under Forestry Minister's decree No. P 11 / Menhut-II / 2008. After the amendment in 2010, however, the ground was shifted to Forestry Minister's decree No. P 50 / Menhut-II / 2010, trimming the procedure to obtain afforestation license into a little simplified one.

This study is aimed to analyze the economic effectiveness (direct fishing income effect) of the marine afforestation project in Gangneung region. Based on the surveyed data, the production values and costs of the marine afforestation project are estimated and compared to determine the economic validity of the marine afforestation project. Results show that the B/C ratio, as an indicator of economic evaluation, is 1.30 with an interest rate of 5.5%, indicating that the marine afforestation project in Gangneung region would be economically feasible under the current production and market conditions. However, it is expected that the economic effectiveness would be increased when considering benefits of recreational fishing and greenhouse gas reduction from the marine afforestation project.

Desertification in China, one of the source regions of yellow dust, has been worsen by industrialization and extreme land development, which increases the damage caused by yellow dust in Korea. Because the yellow dust from China affects not only their own country, but also neighboring countries, it is becoming an international problem, and China has been started afforestation projects to prevent excessive desertification with the help of the international community. However, it is only possible for identifying the results of afforestation projects to check afforestation result reports from National Bureau of Statistics of China, which makes it difficult to check out tangible results. Therefore, this study was conducted by using remote sensing technique for monitoring afforestation status of Yulin, shaanxi, China. in which an afforestation project has been carried out steadily. MODIS imagery was used as remote sensing data and it was confirmed that vegetation has been increased through vegetation indices from 2000 to 2014 and afforestation areas were estimated as same trend of ground reference data.

This study was conducted at Sitakunda coastal afforestation range, comprised of four beats- Bansbaria, Bakkhali, Baterkhil and Bogachattar, in Chittagong. Afforestation effects on soil physicochemical properties in comparison to adjacent barren land were analysed. In the study area, an area of 3277.33 ha was planted with Sonneratia apetala, Avecinnia officinalis, Excoecaria agallocha, Bruguiera sexangula, Ceriops decandra from 1968 to 2011. We found positive soil physicochemical changes in plantations in comparison to adjacent barren land. Soil bulk density of plantation was lower than the adjacent barren land. Soil pH and soil salinity were significantly higher in barren land whereas soil organic matter, organic carbon, nitrogen, phosphorus, potassium of plantations were higher in afforested land. Soil texture ranged from clay loam to sandy loam in different depth of these two types of land. However, this study concludes that there is clear evidence that afforestation has positive impacts on all soil properties in different location and soil depths in the study area.

As marine desertification and chlorosis in Korean coast have been intensified over time, Korean government is promoting marine afforestation projects. However, marine afforestation location is mainly decided by administrative convenience. Also, there is limited literature on location suitability about the marine afforestation. This study aims to assess location suitability of marine afforestation considering 3 significant criteria: ecological, submarine topographical, and human-social environment. Jeju, the study area of this study, first observed chlorosis in Korean coast at the small fishery town in Seogwipo. Jeju is currently suffering from chlorosis all around the island. Habitat Evaluation Procedure (HEP), 3D kriging, Analytic Hierarchy Process (AHP) is applied as analysis methods. Especially, 3D kriging is utilized for modeling 3D ocean space reflecting ocean environment appropriately. The result shows that Jocheon coast has better location suitability than Seogwipo Pyoseon coast. Jocheon coast has the maximum 61% suitability as the habitat of Ecklonia cava Kjellman, and is highly evaluated in other criteria. The results of this study are expected to find optimal marine afforestation location, and to contribute to the restoration of the Jeju coastal ecosystem and the revitalization of Jeju fishing village societies.

As biodiversity loss has been highlighted as a global risk, biodiversity activities are gaining attention as a part of companies' Environmental, Social, and Governance (ESG) related management. This study evaluates various biodiversity activities of corporations based on domestic and international indicators. We present the role of corporations expressly in afforestation activities and suggest additional information that should be disclosed for the accurate verification of environmental values by third parties. KT&G was selected as the subject of the evaluation. The 4th National Biodiversity Strategy was used as a domestic indicator, and GRI Standard 304 as an international indicator. Companies can play a leading role in planning, implementing, and monitoring afforestation activities and should further disclose the species composition of the forests created and the age of the seedlings to enhance the credibility of the environmental values stated in their sustainability reports.

To arrange artificial reefs for marine afforestation effectively, tidal currents were analyzed by numerical experiments, and particle tracking based on tidal currents was carried out to clarify the path of algae spores. The experiments were conducted by the Environmental Fluid Dynamics Code (EFDC), and water column was vertically divided into five layers. Tidal current patterns were showed to be affected by main currents outside of the study area, and two circle currents were observed during the analysis of residual currents. Particle tracking lasted 15 days at three installation places where artificial reefs for marine afforestation could be deployed. According to the results of the particle tracking experiment, particle movements at the No.1 and No. 3 stations were belt types along the coastal line. The No. 2 station documented an ellipse type movement 300~500m from coast line. These results suggest that artificial reefs for marine afforestation should be installed in the belt zones at of the No. 1 and No. 3 stations, and in the ellipse zone at the No. 2 station.

To arrange effectively artificial reefs for marine afforestation, tidal currents were analyzed by numerical experiments. The numerical experiments were carried out by EFDC(Environmental Fluid Dynamics Code), and water column was vertically divided 5 layers. Tidal current patterns showed to be affected by main current at outside of study area, and circle currents of two were observed from analysis of residual currents. The calculated harmonic constants of tide and tidal current agreed well with those of observations at two stations for tide and two stations for tidal current. The model successfully reproduced the tidal current around the Geomoondo marine afforestation. It suggest that artificial reefs for marine afforestation should be installed belt zone at study area.
