"Adaptive forestry"
Evaluation of genetic resources for strengthening productivity and adaptability of tropical forests
2025-09-25
Background
Tropical forests are rich in diversity and have trees with a variety of excellent properties for timber. However, the harvesting of natural forest timber is not sustainable due to the uncertainty of subsequent resource regeneration, and the depletion of resources is limiting natural forest timber production and switching production to plantation timber. Therefore, there is a need to develop afforestation technologies for degraded secondary forests, abandoned cultivated lands, and other areas with high afforestation needs, in order to restore timber production capacity. Furthermore, many of the major tree species in natural forests are susceptible to the effects of climate change, and it is necessary to establish sustainable tropical forest management using diverse forest genetic resources with high environmental adaptability.
Objectives
This project aims to clarify the characteristics, functions, and adaptability to environmental changes of the indigenous genetic resources of tropical forests in Southeast Asia and other regions, and to develop silviculture technologies to enhance forestry productivity and environmental adaptability based on this information.
Research Themes
- Characterization of tropical forest genetic resources for enhanced productivity and environmental adaptability
- Development of silviculture techniques that take into account the impact of vegetation change on ecosystem functions
- Networking of indigenous genetic resource management information and sharing of utilization methods
Target Countries
Malaysia, Indonesia, Thailand
Target Beneficiaries
Government of partner countries, state forest agencies, foresters and forestry enterprises
Project Leader
ABE Hisashi (Forestry Division)

International Workshop on Environmentally Adaptive Forestry Held at Gadjah Mada University, Indonesia
On February 9–10, 2026, an international workshop titled “Environmentally Adaptive Forestry Techniques for Southeast Asian Tree Species” was held in Yogyakarta, Indonesia. The workshop summarized the achievements of the medium- and long-term plan under the grant-funded project “Environmentally Adaptive Forestry.” Launched in fiscal year 2021, this project aims to develop technologies for the restoration of forest resources in tropical forests degraded by overharvesting and to establish methods for selecting tree species and varieties with enhanced environmental adaptability.
