Deforestation, land degradation, and unsustainable land management threaten our lives and are responsible, both directly and indirectly, for many economic, social and environmental issues. In particular, countries in Northeast Asia face the growing threats of desertification, land degradation and drought (DLDD). In China, it is estimated that “more than 40 per cent of Chinese arable land is degraded” (China Daily 2014). “The annual cost of land degradation in Mongolia is estimated at 2.1 billion United States dollars (USD)” (UNCCD, 2018).

This study attempts to confirm the differences in carbon sink according to each type of land use by using the biotope map and reviewing carbon sink considering topography, and comparing those before-and-after topographic correction. The types of carbon sink were focused on Normalized Difference Vegetation Index (NDVI), Leaf Area Index (LAI) and Net Primary Productivity (NPP).

Decomposition, nutrient, and isotopic (deltasup(13)C and deltasup(15)N) dynamics during 1 year were studied for leaf and twig litters of Pinus densiflora, Castanea crenata, Erigeron annuus, and Miscanthus sinensis growing on a highly weathered soil with constrained nutrient supply using litterbags in a cool temperate region of South Korea. Decay constant (kl year) ranged from 0.58 to 1.29/year, and mass loss ranged from 22.36 to 58.43 % among litter types.

Degradation of forests can have severe negative local impacts and far-reaching consequences, including soil erosion, loss of biodiversity, greenhouse gas emissions, dust storms, diminished livelihood opportunities and reduced yields of forest products and services. Reversing the adverse conditions requires urgent and scaled-up action, through scientific and holistic landscape-level restoration approaches, balancing both socio-economic and environmental goals and the diverse needs of various sectors and stakeholders in the landscape.

There are numerous global, regional, national and even subnational targets for increasing forest area and forest restoration. In light of these global targets and emerging ambitious national commitments, it is imperative to develop low-cost strategies and techniques for landscape restoration. The most widely used restoration strategies involving planting of tree seedlings are often costly and their application for restoring vast expanses of degraded forest lands in the region may be limited.

This edition of Unasylva comes in the wake of the United Nations Conference on Sustainable Development, Rio+20,which, among other things, produced a document called The Future We Want. In it, world leaders renewed their commitment to sustainable development and stated that “the wide range of products and services that forests provide creates opportunities to address many of the most pressing sustainable development challenges”. Foresters should be pleased with these words because they indica te that forests are starting to get the recognition they deserve.

North Korea used to have abundant forest stocks but underwent substantial deforestation and degradation of forest in recent decades. This study examined morphological changes of forest cover in North Korea between the 1980s and 2000s. Land cover data based on Landsat TM imagery were obtained as images from the Republic of Korea’s Ministry of Environment. The images were processed and used for the morphological spatial pattern analysis (MSPA) and network analysis. MSPA classified the forest cover into morphological classes such as core, islet, bridge, perforation, edge, loop, and branch.
