    A study on the ecotourism cooperation using the forest cultural heritage in South and North Korea - Focusing on the Geumgangsan Yusan-gi (Geumgang mountain travels)

    Forest restoration and ecological protection in North Korea require a variety of approaches.
    This research focuses on the Geumgangsan Yusan-gi, a shared forest cultural heritage between the two Koreas, to find ways to collaborate with ecotourism.
    Is ecotourism a novel approach to Inter-Korean forest cooperation?
    What are the advantages and prospects of working together on ecotourism projects centered on the Geumgangsan Yusan-gi?
    To achieve the study's goal, North Korean literature data were reviewed and analyzed, and value models for ecotourism cooperation were investigated using content analysis of the Geumgangsan Yusan-gi.
    Inter-Korean forest cooperation has primarily focused on planting and management to prevent forest devastation in North Korea.
    Forest cooperation needs to develop into a scalable project that connects peace and tourism.
    Ecotourism has the potential to be a new model for inter-Korean forest cooperation.
    First, ecotourism cooperation pursues reciprocity.
    Second, ecotourism is a sustainable project different from one-time support.
    Third, ecotourism can be backed by the international community and promoted readily in the face of North Korean sanctions.
    Fourth, the ecotourism cooperation project is in line with the Kim Jong-un administration's current tourism policy.
    Fifth, the inter-Korean collaboration project based on the two Koreas' shared forest cultural legacy is a unique initiative rooted in Korea's history and tradition.
    The Geumgangsan Yusan-gi can promote ecotourism cooperation, such as joint inter-Korean investigation and program development and operation.
    To become a reality rather than a pipe dream, this proposal must overcome some obstacles, including the US and international community sanctions against North Korea.
    Civil society organizations, such as forests and environmental organizations, play an important role in peace initiatives such as ecotourism and forest cooperation.

    Analyzing the occurrence trend of sediment-related disasters and post-disaster recovery cases in mountain regions in North Korea based on a literature review and satellite image observations

    This study investigated spatiotemporal trends of sediment-related disasters in North Korea from 1960 to 2019 and post-disaster recovery cases based on a literature review and satellite images. Results showed that occurrence status of sediment-related disasters was initially externally reported in 1995 (during the Kim Jongil era); their main triggering factor was heavy summer rainfall. Furthermore, forest degradation rate was positively correlated with population density (R2 = 0.4347, p = 0.02) and occurrence number of sediment-related disasters was relatively high on the west coast region, where both variables showed high values. This indicates that human activity was a major cause of forest degradation and thus, significantly affected sediment-related disasters in mountain regions. Finally, sediment- related disasters due to shallow landslides, debris flow, and slow-moving landslides were observed in undisturbed forest regions and human-impacted forest regions, including terraced fields, opencast mines, forest roads, and post-wildfire areas, via satellite image analysis. These disaster-hit areas remained mostly abandoned without any recovery works, whereas hillside erosion control work (e.g., treeplanting with terracing) or torrent erosion control work (e.g., check dam, debris flow guide bank) were implemented in certain areas. These findings can provide reference information to expand inter-Korean exchange and cooperation in forest rehabilitation and erosion control works of North Korea.

    A preliminary study on ecological features of two natural enemies against two vectors of pine wilt disease for mass rearing in Korea

    Two species of the genus Monochamus (Coleoptera: Cerambycidae), M. alternatus and M. saltuarius are well-known as vectors of the pine wilt disease and they causes economically damages in South Korea. Among various control methods to reduce the density of vectors, a method by biological control agents (natural enemies) is eco-friendly indispensable. Since 2017, we have carried out the studies on the parasitic natural enemies againt for the vector species and found two parasitoids, Spathius verustus Chao, 1977 (Braconidae) and Cyanopterus flavator (Fabricius, 1793) (Bracondiae), would be a useful agents for biological controls. For accumulation of biological data, we conducted a preliminary study on life span and parasitic rate of two parasitic wasps against for two vector species. As results, we found that S. verustus has the longest adult life span of 33.4±19.2 days (avg.) in M. alternatus (T=30°C, H=60%) and C. flavator has the longest adult life span of 25.1±10.6 days (avg.) in M. alternatus (T=25°C, H=60%). The average parasitic rate (62.5%) of S. verustus was highest in M. alternatus (T=30°C, H=60%). In addition, it is confirmed that the offsprings of S. verustus can be made by parthenogenetic reproducton. Keywords: Research ID: 3622037

    The impact of climate variability and extremes on agriculture and food security - An analysis of the evidence and case studies
    Background paper for The State of Food Security and Nutrition in the World 2018

    Also available in:

    Global climate studies show that not only temperatures are increasing and precipitation levels are becoming more varied, all projections indicate these trends will continue. It is therefore imperative that we understand changes in climate over agricultural areas and their impacts on agriculture production and food security. This study presents new analysis on the impact of changing climate on agriculture and food security, by examining the evidence on recent climate variability and extremes over agricultural areas and the impact of these on agriculture and food security. It shows that more countries are exposed to increasing climate variability and extremes and the frequency (the number of years exposed in a five-year period) and intensity (the number of types of climate extremes in a five-year period) of exposure over agricultural areas have increased. The findings of this study are compelling and bring urgency to the fact that climate variability and extremes are proliferating and intensifying and are contributing to a rise in global hunger. The world’s 2.5 billion small-scale farmers, herders, fishers, and forest-dependent people, who derive their food and income from renewable natural resources, are most at risk and affected. Actions to strengthen the resilience of livelihoods and food systems to climate variability and extremes urgently need to be scaled up and accelerated.

    Rinderpest and its eradication 2022
    Also available in:
    No results found.

    This book tells the story of rinderpest and its eradication. The focus is on the international coordination that came together after the Second World War in the confident belief that, with vaccines available, the eradication of rinderpest was a practical possibility. In both Africa and South Asia, beginning in the 1960s, there was an initial dramatic success through the coordinated vaccination of cattle across the continents. Unfortunately, follow-up measures could not prevent the return of epidemic rinderpest, albeit to a lesser extent. Chastened by failure, the international community refocused with renewed energy to achieve eradication. The vaccination programmes broadened to reflect a multidisciplinary approach to disease eradication. FAO and the OIE, together with international aid agencies, coordinated policy with the nation states and guided implementation of the era¬dication programmes until success was achieved.
