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

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.

ArticleWho visited urban forests and trails more or less during the COVID-19 pandemic and why? A case study in Salt Lake City, UT, USA

No results found.While the COVID-19 pandemic caused a decrease in travel and social activities, there was an exception—travel to parks and trails. Urban residents needed refuge to relax, exercise, and socialize. Nevertheless, trips to parks and trails vary by socio-demographic characteristics, disadvantageous to those having health issues or low-income. Without appropriate community design and planning interventions, such conditions may worsen existing environmental injustice and health issues. This study explores the demographic profile of those who used urban parks and trails more or less during the COVID-19 pandemic in Salt Lake City, UT, USA. Data comes from an online and intercept survey with 4,325 responses and focus groups with 52 participants. Quantitative analyses show that park and trail use during the pandemic decreased among older adults, females, homeowners, and low- income households. Also, people living in a denser, more walkable, and more park/trail accessible neighborhood likely increased their visitations.Our qualitative analysis further examines how residents feel about their use of parks and trails during the pandemic and how they would improve them in the future. Respondents in disadvantaged neighborhoods felt safe visiting parks, highlighting the value of urban nature as a resilience infrastructure and community asset during a crisis. This study presents transformative ideas to engage communities and promote stewardship, which are relevant to cities looking into the New Normal.

ArticleAssessing the impacts of COVID-19 pandemic on the livelihoods of forest-dependent communities: A case study of communities in Oluwa forest reserve, Nigeria

No results found.Though the COVID-19 pandemic is primarily a health crisis, it has a worldwide impact on the communities and economies. This impact has resulted in global socio-economic disruptions and diminished people’s livelihoods. Meanwhile, forests provide economical and livelihood support for many people around the world. For example, one-fifth of the global population depend on forest products for livelihoods and forty per cent of the extreme poor in rural areas live in and on forests. However, restrictions on physical activities as a measure to combat the pandemic also impacted forestry activities, which has put forest-based livelihoods at risk. Quantifying the impacts of the COVID-19 pandemic on forest-based livelihoods could help to better support and economically empowered people whose lives depend on the forests. Therefore, six communities were randomly selected in and around Oluwa forest reserve, Nigeria and a structured questionnaire was used to collect primary data from respondents using purposive sampling. The data collected was analysed using descriptive and inferential statistics to understand the impacts of the COVID-19 pandemic on the livelihoods of forest-dependent communities in Oluwa forest reserve in Nigeria. The findings from this study could be a valuable resource to rebound from the impact of the crisis. Additionally, this study could potentially strengthen the response to the pandemic and improve the resilience of forest-dependent communities.
