山水轮回

长久以来,我们一直相信,山水是无言的,是静默的。然不知,在自然的轮回之中,在四季的更替、日夜的交换之中,山水从未停止过它行走的步伐。正如我们文中的泰山,谁又能否认     

佛在山水间

在常熟遍访古刹名寺,对于我这个学园林出身的人,是历年来行走江湖中有关寺观园林的现场写生实录版了。 漫步在春目的深山嶝岩之下,体味禅意盎然的“无人之境”,呈现了天地间的白云幽石、青山绿水、乌语花香、清风明月、池泉古寺等自由清静的形象,其中隐隐然皆有佛在,可说是以佛对山水,以禅悟天地,亦即所谓“青青翠竹,总是法身;郁郁黄花,无非般若,真是合了庄子的”山林与,皋壤与,使我欣欣然而乐与”的境界。     

Climate change and conflict

The prospect of human-induced climate change encourages drastic neomalthusian scenarios. A number of claims about the conflict-inducing effects of climate change have surfaced in the public debate in recent years. Climate change has so many potential consequences for the physical environment that we could expect a large number of possible paths to conflict. However, the causal chains suggested in the literature have so far rarely been substantiated with reliable evidence. Given the combined uncertainties of climate and conflict research, the gaps in our knowledge about the consequences of climate change for conflict and security appear daunting. Social scientists are now beginning to respond to this challenge. We present some of the problems and opportunities in this line of research, summarize the contributions in this special issue, and discuss how the security concerns of climate change can be investigated more systematically.

Climate change-induced migration and violent conflict

In a world of rising sea levels and melting glaciers, climate change is most likely occurring but with uncertain overall effects. I argue that we can predict the effects of climate change on migration by exploring the effects of environmental problems on migration in recent decades. People can adapt to these problems by staying in place and doing nothing, staying in place and mitigating the problems, or leaving the affected areas. The choice between these options will depend on the extent of problems and mitigation capabilities. People living in lesser developed countries may be more likely to leave affected areas, which may cause conflict in receiving areas. My findings support this theory, and suggest certain policy implications for climate change.     

Climate and the Chronology of Iranian History

This article offers a chronology of climate events in Iran over the last millennium to challenge traditional chronologies of the Iranian past based on politics, war, and economics. Using insights gleaned from the historiography of climate in Iran, and from neighboring regions, especially the Ottoman Empire, four episodes of climate cooling show how climate-induced environmental processes affected more people for longer in Iran than did the policies of the empires ostensibly ruling over them. Thus, the article aims to put climate more squarely on the agenda of historians of Iran so that the conjectures advanced here can be confirmed, revised, or discarded through future empirical research. Moreover, the article seeks to bring Iran into wider conversations in environmental and global history.
