This session, organised by the IUFRO Task Force on “Forest Adaptation and Restoration under Global Change”, discussed various aspects of restoring forest ecosystems under conditions found in the Asia and Oceania regions.
In the first presentation, John Stanturf (US Forest Service) explained the potential benefits that forest landscape restoration can have on mitigating as well as adapting to climate change. These included aspects such as diverse species and structures at stand scale; age classes of tree vegetation at landscape scale and connectivity. Read more…

Studies presented in this session examined the dynamic interrelationship between forest transition and economic, social and political changes, and discussed the implications for forest policy.
As we entered the Anthropocene, human influence became increasingly stronger causing great forest decline, particularly from 1920 onwards. Direct drivers of forest decrease include, among others, population growth and agricultural expansion. Read more…
Keynote Presentation by Don Koo Lee, Seoul National University, Korea, Tuesday 25 Oct 2016
This most inspiring talk about the important roles of trees, soil and forests for human life highlighted ways of how to achieve sustainable development and showcased success stories, especially the historic achievement of reforesting Korea.
The goods and services provided by forests are manifold and indispensable for people and the environment. Forests are crucial, among other things, for stabilizing soil, providing water resources, supporting biodiversity, protecting against natural hazards, delivering timber and non-timber products, and, quite importantly, combatting climate change. In order to ensure that future generations will be able to enjoy the same benefits from forests, sustainability is indispensable in the management and use of natural resources. Read more…

The session offered insight into functional ecology, with emphasis on climatic conditions along elevation gradients showing that biodiversity decreases with increasing altitude. It also dealt with the provision of ecosystem services in relation with biodiversity. Biodiversity is essential for pest damage resistance, for example. Source dilution, chemical signals and activity of natural enemies are identified as being essential for ensuring low pest damage. With increased source dilution, pests are less likely to establish themselves in a diverse setting. With increased chemical signals associated with diverse flora, pests are less likely to find their favourite source. And with a high number of natural enemies, whose presence is correlated with high biodiversity, pests are less likely to cause damage. Hence, diversification on a stand/landscape level is needed to ensure the provision of forest ecosystem services.
Plant conservation in Southeast Asia was another topic. In Malaysia, for example, efforts to preserve plants have become a prevalent goal for scientists. Diversity is vast, and since 40 – 50 % of the preserved species are endemic, 24% of which are either endangered (EN) or critically endangered (CR), conservation is a central goal. While the pleas of scientists are being heard in some cases, legal frameworks are needed to protect these species.
A presentation on the carbon sequestration potential for complex mosaic forest landscapes in western Mexico aimed at addressing shifting cultivation, framed in the carbon emission discourse. With shifting cultivation, carbon is released to the atmosphere, adding to GHG concentrations. However, the study showed that on a landscape level, there are no net carbon dioxide emissions, as the carbon sequestration rate of forest re-growth compensates for the carbon emission from shifting cultivation.
The presentation entitled “Native forest cover increase: drivers and implications on ecosystem services”, focused on why some areas in the Piracicaba river basin were allowed to reforest. Satellite imagery helped determine deforestation and reforestation from 1990 – 2010. Having preselected variables, the results demonstrate that natural reforestation occurs when slopes exceed 30%, when water proximity is less than 100 m, when annual rainfall exceeds 1400 mm, when elevation is lower than 400 m below sea level or more than 800 m above sea level, and when vicinity to towns is more than 7 km.
The final paper focused on Chakras, forestry systems that are employed by indigenous peoples in the Amazon. Plant composition in Chakras is heterogeneous; they provide multiple sources of food, are biodiverse and function as stores of carbon. The presented study demonstrated that in Chakras, fauna is more diverse, carbon storage is higher in both biomass and necromass than in comparable Cocoa plantations.
