In recent years, forest fires have been increasing in both frequency and scale due to extreme dryness, which is believed to be a result of climate change. In the Amazon, in particular, uncontrolled burning for land conversion has caused large-scale forest fires, and international discussion on how to solve this problem is progressing. Furthermore, there have been reports that forest residues left in degraded forests are contributing to larger fires. Forest fires not only release forest carbon into the atmosphere but also affect forest soils and soil moisture. The process by which disturbed forests recover and self-heal is unclear.

In the Andes, where deforestation and forest degradation are increasing, local residents have been actively planting eucalyptus trees to meet the demand for wood resources. Recently, people living in the mountainous areas have become suspicious that, in addition to the aridification resulting from climate change, eucalyptus plantations are using a considerable amount of water resources, which may be reducing the supply of water for agricultural land. To optimize the allocation of water resources to various land uses, it is necessary to estimate the amount available from the supply and demand of water resources.

To develop a forest management system model for local communities to conserve and utilize forest ecosystem services sustainably in the Andean-Amazon.

1) Identify time-series land use change by taking into account the forest carbon stock change and the degree of forest degradation.
2) Develop a technology for the quantitative assessment of deforestation and forest degradation.
3) Develop a method for the assessment of forest recovery processes after fire disturbance.
4) Develop a landscape optimization system with a water resource model.
5) Develop a forest management system model to realize better usage of ecosystem services in consideration of socioeconomic characteristics and science-based scenarios.
6) Apply a forest management system model to enhance sensible decision-making with local communities.

A system will be developed to support appropriate forest allocation and forest management to maximize co-benefits from forests through establishing a harmony between local needs, such as the use of wood and water resources by local residents, with global needs, such as the reduction of carbon emissions and the conservation of biodiversity through the control of both deforestation and forest degradation. Workshops will be held to disseminate the forest management system to various stakeholders to enable the developed forest management system to be used by the community.
