ArticlePrediction of distribution changes of carpinus laxiflora and C. tschonoskii based on climate change scenarios using MaxEnt model in the Republic of Korea
XV World Forestry Congress, 2-6 May 2022

No results found.Hornbeams (Carpinus spp.), which are widely distributed in South Korea, are recognized as one of the most abundant species at climax stage in the temperate forests. Although the distribution and vegetation structure of the C. laxiflora community have been reported, little ecological information of C. tschonoskii is available. Little effort was made to examine the distribution shift of these species under the future climate conditions. This study was conducted to predict potential shifts in the distribution of C. laxiflora and C. tschonoskii in 2050s and 2090s under the two sets of climate change scenarios, RCP4.5 and RCP8.5. The MaxEnt model was used to predict the spatial distribution of two species using the occurrence data derived from the 6th National Forest Inventory data as well as climate and topography data. It was found that the main factors for the distribution of C. laxiflora were elevation, temperature seasonality, and mean annual precipitation. The distribution of C. tschonoskii, was influenced by temperature seasonality, mean annual precipitation, and mean diurnal rang. It was projected that the total habitat area of the C. laxiflora could increase by 1.05% and 1.11% under RCP 4.5 and RCP 8.5 scenarios, respectively. It was also predicted that the distributional area of C. tschonoskii could expand under the future climate conditions. These results highlighted that the climate change would have considerable impact on the spatial distribution of C. laxiflora and C. tschonoskii. These also suggested that ecological information derived from climate change impact assessment study can be used to develop proper forest management practices in response to climate change.

ArticleSustainability performance model through local community participation towards the development of sustainable community-based tourism on nature-based sites in Bicol region, Philippines
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Community-based tourism in the Philippines thrives on natural areas both protected and non-protected. In this regard, the participation of tourism stakeholders and their sustainability performance is essential to determine actions and programs to ensure environmental protection and the provision of long-term benefits. This study evaluated the extent of participation of the local tourism stakeholders in the identified community-based tourism (CBT) sites in Bicol Region, Philippines, and determine its influence on sustainability performance. The sustainability performance indicators were anchored from various international CBT indicators and employed the ASEAN Community-Based Tourism Standard as the baseline criteria. The participants of the study consist of the members of CBT organizations, the Local Government Unit, full-pledged municipal tourism officers, tourism officers-designate, barangay officials, private stakeholders, NGOs, and tourists. This study used a descriptive research method and utilized qualitative and quantitative analysis. Results showed that all factors of the extent of participation relate significantly to the overall sustainability performance but to a varying degree. The analysis of the extent of participation and sustainability performance showed significant differences among each community with moderate association to one another. The significant predictors for sustainability performance were political maturity, cultural richness, and environmental purity. Political maturity registered the highest effect on sustainability performance. It can be concluded that in the context of Bicol Region, government and political support determines success in tourism development alongside cultural and environmental dimensions of tourism sustainability. Therefore, it is recommended to adopt the Sustainability Performance Model for CBT sites in Bicol Region.

ArticleEstimation of the productivity of silvoarable systems established under Juglans regia L. with the Yield-SAFE model
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Galicia (NW Spain) is characterized because two-thirds of its area is classified as forest. In the last years, the forest land has increased gradually in this region which decreases the availability of agricultural land. These factors could favour the establishment of silvoarable systems in Galicia, in which trees are intercropped with annual or perennial crops on the same unit of land. The productivity of silvoarable systems is highly difficult to predict due to the interaction of many biophysical and management factors. One option to determine the productivity, as well as the environmental benefits of the silvoarable systems compared to the traditional agricultural and forest systems, could be the use of models like Yield-SAFE. The Yield-SAFE is a biophysical model to predict the long-term production according to light and water availability in exclusively agricultural and forest systems and also in agroforestry systems. This study aimed to estimate the productivity of silvoarable systems established with maize under Juglans regia L. in Galicia (NW Spain) with the Yield-SAFE model taking into account different scenarios of climate. The results show that the Yield-SAFE model can be used as a management tool to optimise land use productivity under an agroforestry context. Keyword: Climate change ID: 3623935
