报告人简介：
Dr. Peter Clinton, is a internationally-recognised forest ecologist. with more than 35 years of experience in delivering excellent science with impact for New Zealand’s forestry sector through his leadership of successful government-funded research programmes. His research interests cover Carbon and nutrient dynamics and plant soil interactions with a particular focus on maintaining the productive capacity of commercial forests. He is one of New Zealand’s leading experts in sustainable forest management and his expertise extends to production ecology, tree nutrition, biogeochemistry and the sustainability of forest soils. He is a Fellow of the New Zealand Institute of Forestry.
Peter led the diverse multi-disciplinary and multi-year forestry research (‘Growing confidence in Future Forests’ https://gcff.nz ) and now leads the Resilient Forests programme https://www.scionresearch.com/science/managing-forestry-risk-and-climate-change/resilient-forests-research-programme which is focused on maintaining the productive capacity of planted forests in face of an uncertain future. He has an extensive publications record (>110 international peer-reviewed papers) on the ecology and management of natural and planted forests.
报告内容简介：
Climate change presents several interrelated challenges for forest soils. First, forest ecosystems are essential carbon sinks and reservoirs, providing wood and fiber for traditional uses while also meeting the increasing demand for biomass resources to replace fossil carbon-derived products. The second challenge is how to meet this additional demand. Will it be achieved through the expansion of forested areas, including the harvesting of remaining primary forests, or through increased productivity in existing planted forests while prioritizing biodiversity conservation? Lastly, we expect greater forest disturbances due to climatic events, such as wildfires, extreme winds, floods, diseases, and pest outbreaks. These disturbances threaten the productivity, sustainability, and resilience of forests and their soils, jeopardizing the goals set by the Paris Agreement and the future supply of timber resources. The ability of forest soils to recover from these extreme and increasingly frequent events, coupled with the need to develop more resilient forests, will be a critical issue moving forward.
As well as increasing the resilience of forests and forest soils to disturbances, new management practices will need to be developed to buffer the soil resources against any pressures resulting from intensification (e.g., shorter rotations, higher stocked stands, more disturbance, and residue removal), to meet increased demands. For example, can we enhance soil fertility without using more inputs – by better utilising soil biological resources? To meet these interrelated challenges and address the complexity of the issues, it will be essential to identify priority areas of new research for forest soils, recognizing the views of early career scientists as they will hold different aspirations for their future world. Overall, forest soil scientists will have a large role to play in the global response to climate change.
