Journal articleImpacts of the national forest rehabilitation plan and human-induced environmental changes on the carbon and nitrogen balances of the South Korean forests
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The carbon (C) balance is a key to the climate regulation role of forests, and the nitrogen (N) balance affects forest productivity, ground and surface water quality, and the emission of N2O. Humans have impacted the C and N balances, but quantification of the responses of forests to human activities is limited. This study aimed to quantify the impacts of the long-term national forest rehabilitation plan and the contribution of the increase in air temperature, CO2 concentration, and N deposition on the C and N balance of the South Korean forests during 1973–2020 by using a biogeochemical model. The C and N balance increased from 0.20 to 4.30 Mg C ha–1 year–1 and from 0.20 to 17.4 kg N ha-1 year-1, respectively. This led to the whole South Korean forests to newly store 825 Tg C and 3.04 Tg N after the national forest rehabilitation plan. The increase in air temperature, CO2 concentration, and N deposition contributed –11.5, 17.4, and 177 Tg C for the newly stored C stock, respectively, and –25.4, 8.90, and 1,807 Mg N for the newly stored N stock, respectively. This study would provide references on the benefits of forest rehabilitation for the C and N balance and for future forest rehabilitation efforts. Moreover, our findings improve the understanding of the impacts of human activities on the C and N balance.

Journal articleNTFPs as a source of livelihood and climate change mitigation & adaptation: a case study from Jharkhand, India
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.There is an inextricable link between forest resources and livelihood of rural people .The rural people including tribals – Oraon, Munda, Ho, Savar, Santhal, Birhor, Bhumij etc. living around forest area use these non-timber forest produce (NTFP) as their primary source of income, food, nutrition, and medicine. NTFPs may be used for subsistence or for sale, providing cash income and function as an economic buffer in times of hardships. The paper summarizes activities of livelihood based on NTFPs in Jharkhand .They get employment in activities related to NTFPs like plucking of Tendu leaves (Diospyros sps.), rearing of Silk- (Antheraea mylitta Drury) and cultivation of Lac- (Kerria lacca Kerr), making of fancy items from bamboo and cottage industry based on bamboo. Of these NTFPs, Lac and Silk occupy an important place in rural economy. Lac, which is a natural resin secreted by an insect, Kerria lacca (Kerr.), cultivated on host trees like Palas [Butea monosperma (Lam.) Taub] and Kusum [Schleichera oleosa (Lour.) Oken] .In Jharkhand mostly Tassar Silk is reared which is produced by a wild silkworm of Antheraea mylitta Drury which feeds primarily on host trees like Asan [Terminalia tomentosa (DC) Wt. &Arn].The paper depicts activities of crafts based on bamboo, embroidery on silk cloth and manufacture of decorative items of Lac and other facets of these NTFPs and their contribution in improving earnings of rural people. The paper also critically examines how NTFPs can be effective tool in climate change mitigation and adaptation especially in REDD+. Hence NTFPs are of importance for food security, livelihood option, poverty eradication and for their role in climate change mitigation and adaption. Government policy in India and Jharkhand related to Join Forest Management, enactment of Forest Right Act 2006, and implementing Forest Working plan Code 2014 by, has brought about radical changes in approach towards management of NTFPs.

Journal articleTransboundary forest management strategies are needed to adapt to climate change in East Asian temperate forests
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Cli mate impacts traverse administrative borders, so paradigms that address forest preservation and adaptation strategies across international borders are needed. Here, we measure climate change exposure for forests of the East Asian Temperate Broadleaf and Mixed Forest Biome, which occupies 3,092,381 km2 and covers 18 ecoregions. This Biome includes parts of China, North and South Korea, Japan, and the Russian Federation. We quantify future climate change exposure as the change per pixel in climate conditions relative to the baseline (1960-1990) climate conditions occupied by each forest type and project future climate change exposure levels to each forest type within and among the ecoregions. We use the entire biome and its ecoregions as units within which to quantify climate change exposure. We then examine the resulting spatial patterns of climate change exposure relative to provincial and international boundaries to identify several levels at which governments will need transboundary coordination in order to develop forest preservation and climate adaptation strategies. By 2070, using the RCP8.5 emission scenario, 24.5-65.7% of these forests enter non-analog or the most marginal 1 % of baseline climate conditions. These results reveal the need for extensive transboundary governmental coordination, including forest preservation actions among 51 of 54 provinces that will retain some forest locations in climatically stable or low-risk conditions. Furthermore, among 96 provinces with forests that will be highly exposed, 90 will require transboundary climate change adaptation strategies because these forests span their borders, including the border areas of China, the Russian Federation, and North Korea. The analytical approach of this study could serve as a template for supporting transboundary institutional coordination to address climate change.
