个人简介
Cathy is a postdoctoral research associate at Royal Holloway University of London, in the Leverhulme Centre for Wildfires, Environment, and Society. Her research takes a political ecological approach to examine fire governance and changes in the use and knowledge of fire within rural livelihoods. She previously worked for a community-based fire management project in Belize.

Lessons learned from a century of fire suppression and management in the tropical savannas of Belize
报告摘要
This talk explores the last century of fire management of the coastal pine savanna in Belize. The coastal pine savanna in Belize has long been shaped by human fire use for hunting, agriculture, physical access, and enjoyment. Its flora is ecologically adapted to fire. Yet, for various reasons, fires have been cast as a problem by governmental and non-governmental organizations, since c. 1920. Initially, British colonial foresters deemed fires to be destructive to pine forestry. Later, some organizations began to see wildfires as a nature conservation, human security and/or climate risk. In response, these organizations designed different programs of fire suppression and management. In this talk I examine how these programs have differed, in their design, and in practice. The aims and methods of fire management have changed, but there has been some continuity in the way fire management has played out on the ground. There have been large gaps between plans/policies and fire management in practice. Little has changed: Belize’s diverse and growing rural population has continued to use fire, and the savannas burn, year upon year. Each program of fire management has been designed taking little account of local ecology and politics. Local conditions have, nevertheless, shaped fire management in practice. I argue that this is partly explained by the way in which fire management has often been designed, and funded, from abroad.

云南高原的林火干扰:驱动机制、生态效应与响应
报告摘要
云南及其周边地区是我国两大林火发生热点区域,也是全球热带半湿润-半干旱野火热区之一——中南半岛野火分布区的北延部分。云南野火发生的自然环境条件和人类影响,以及现存植被对林火干扰的响应与适应特征,对于理解该地区植物群落构建和生物多样性维持机制,以及预测未来气候变化情景下的响应具有重要意义。基于遥感、地面林火监测、野外植物群落调查与功能性状分析途径的综合运用,我们试图理解上述问题,以期为该地区的森林生态系统修复与可持续管理提供科学依据。
