ArticleThe change in forest productivity and stand-dynamics under climate change in East Asian temperate forests: A case study from South Korean forests
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The velocity and impact of climate change on forest appear to be site, environment, and tree species-specific.The primary objective of this research is to assess the changes in productivity of major temperate tree species in South Korea using terrestrial inventory and satellite remote sensing data. The area covered by each tree species was further categorized into either lowland forest (LLF) or high mountain forest (HMF) and investigated. We used the repeated Korean national forest inventory (NFI) data to calculate a stand-level annual increment (SAI). We then compared the SAI, a ground-based productivity measure, to MODIS net primary productivity (NPP) as a measure of productivity based on satellite imagery. In addition, the growth index of each increment core, which eliminated the effect of tree age on radial growth, was derived as an indicator of the variation of productivity by tree species over the past four decades. Based on these steps, we understand the species- and elevation-dependent dynamics. The secondary objective is to predict the forest dynamics under climate change using the Perfect Plasticity Approximation with Simple Biogeochemistry (PPA- SiBGC) model. The PPA-SiBGC is an analytically tractable model of forest dynamics, defined in terms of parameters for individual trees, including allometry, growth, and mortality. We estimated these parameters for the major species by using NFI and increment core data. We predicted forest dynamics using the following time-series metrics: Net ecosystem exchange, aboveground biomass, belowground biomass, C, soil respiration, and relative abundance. We then focus on comparing the impact of climate change on LLF and HMF. The results of our study can be used to develop climate-smart forest management strategies to ensure that both LLF and HMF continue to be resilient and continue to provide a wide range of ecosystem services in the Eastern Asian region.

ArticleIntegrating adaptive management strategies for coping with climate change impacts on farming households in forest communities of Nigeria
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Most Nigerians depend on natural ecosystems such as forests, for extensive rain-fed farming and short fallow periods. Forest communities interact with their ecosystems for income, food, nutritional security and livelihood sustenance. It is important to determine the response of these communities to climate change vulnerability through modified livelihood activities. A multi-stage sampling procedure was used to assess the perceived impact of climate variability on farming communities in major ecosystems (rainforest, savannah and mangrove) of Nigeria. Using focus group discussions, we identified perceived impacts, traditional adaptive measures and new technologies that communities were adopting to cope with climate change. Over the last 30 years, there were perceived shifts in the rainfall patterns, durations and intensities with negative effects on rain-fed agriculture. Planting operations and cropping calendars had been altered, especially in the savanna, which had the highest incidence of drought and flooding. Climate variability negatively affected food production and available land for farming. Livelihoods most impacted were farming, hunting, fishing, timber and non-timber forest products’ collection. High temperatures, illegal logging and charcoal production were the most important environmental drivers of climate change. While poor governance, poverty and unemployment were the key political and economic elements. Local adaptation strategies included crop rotation, mixed cropping, diversification of trade, water conservation and adjustment of planting calendars based on traditional weather forecast. Sustainable adaptation strategies required included provision of credit facilities, affordable insurance policy; increased supply of drought and disease resistant crops; road networks, favourable forestry regulation; and improved climate information systems. Farmers were struggling with adaptive strategies and required external assistance to cope with climate change.

DocumentReview of methodology on climate change impact and vulnerability assessment for application to the forest sector in Republic of Korea: The first step for mainstreaming adaptation in forest sector
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.As the two laws, The Framework Act on Agriculture and Fisheries, Rural Community and Food Industry and The Creation and Management of Forest Resources Act, were revised in 2015 and 2019, respectively, the Korean government made it mandatory for Korea Forest Service to report the results of climate change impact and vulnerability assessment on forest sector. For implementing the above duty, the National Institute of Forest Science (NIFoS) has categorized the forest sector to eighteen detailed sectors and established monitoring framework to assess the climate change impacts since 2015.
This study aims to develop appropriate methodology and framework for assessment of climate change impact and vulnerability on forest sector in Korea by reviewing what the NIFoS has conducted in comparison with the previous cases in the USA, Canada and the UK. To achieve this, this study first clarifies the ultimate goals of assessment and categorizes assessment areas for each detailed sector. Then, by reviewing the major factors on vulnerability assessment used in the Adaptation Partners Frameworks (USA), the Climate Change Response Framework (USA), the Canadian Council of Forest Ministers Framework (Canada), and the Climate Change Risk Assessment (UK), this study draws the possible stepwise check list with the hope of producing appropriate results on climate change impact and vulnerability which can be utilized in the stage of mainstreaming adaptation in forest sector. The tentative framework drawn from this study contains the considerations about where we need to go and how to go for achieving adaptation.
This study is expected to contribute to establish the essential basis for supporting decision making for finding actual tools to conserve and enhance forest ecosystem services and sustain life of human being under climate change pressure.
