Bushfires (landscape fires) are a key Earth system process that affects humans and our societies and economies. In a recent article, we explored the coupling of humans to landscape fire through the lens of human health impacts of bushfire smoke. We noted that such an approach demands recognition of the indirect impacts and costs of bushfires that cannot be captured by simplistic proxies such as deaths directly attributable to a fire front. Evaluation of direct and indirect economic costs of bushfire disasters, and bushfire fire management remains a poorly developed research frontier that demands collaboration of expertise from a broad cross‐section of fields that often have limited experience of collaborating together. The need for such synthetic thinking about fire's place on Earth has spawned the discipline of pyrogeography.  相似文献

中国古代文明可持续发展的原因分析   总被引:2,自引:0,他引:2  
中国古代文明持续发展,在世界文明史上是极为少见的。究其原因为,一方面是地理环境的基础作用,独特地理位置、封闭而又复杂的地理环境使其然;另一方面,中国古代大一统的历史和文化起着决定性的作用。相对封闭、完整且一脉相承的文化是其内在动因;人口、土地开发和技术水平三者关系的协调是其前提;先进的农耕制对土地资源的保护是其基础;文明中心随环境而变迁,保证了古代文明的持续发展。  相似文献

土地资源是人类生存的基本资料和劳动对象,是人地关系系统中一个重要的物质信息载体,是评价人类生境的一个重要对象。土地利用是人类在现阶段生产力水平下,对区域土地资源的开发程度和利用情况。土地资源的现状评价,是反映人地关系协调程度的一个重要手段。本文采用目前广泛使用的GIS先进技术手段,对青海省海北藏族自治州土地资源的利用现状进行了评价。表明了GIS技术对该区域土地利用评价起到了缩小工作量,提高精确度的作用。并且从土地利用角度对海北州人地关系现状进行了描述。  相似文献

A wide range of digital innovations has changed property relations globally over the past fifteen years. What are we to make of these digital experiments with landed property? I argue we should not mistake their technological novelty for a break with the geographic and historical specificities of property relations. The yoking of property to modernity and civilization makes technological progress a fundamental part of how relationships to land are constituted and reconstituted, and in whose interests, throughout global capitalism. In this article, I situate 21st century housing market technologies within sedimented relations of landed property in the United States, showing the history of property innovation in the United States is also one of racialized wealth accumulation and dispossession. I interpret current anxieties about ‘robot landlords’ as anxieties about how the shifting landscape of property ownership appears to threaten the economic benefits associated with racial dominance.  相似文献

In post-socialist Budapest, gentrification has remained modest for decades after the regime change (1989) due to politically controlled economic relations besides marketisation. Political control was transformed but maintained after 2010 in the illiberal Orbán regime. Populist housing privatisation for tenants, insufficient regulation of rental housing, mortgage policy and urban rehabilitations with systemic corruption caused moderate level of housing market commodification. However, gentrification accelerated from 2014. Among other factors, the restriction of mortgage lending and the unplanned expansion of tourism increased the commodification of real estate market. Similar contextual issues were mentioned in the gentrification literature before; however, they remained external modifying effects of the assumed nomothetic political economic mechanisms behind rent gaps under neoliberal governance assumed everywhere. We suggest connecting institutional, social and political factors with dynamics of land rent through the concept of commodification and its effects on potential ground rent to include them within the mechanisms of gentrification.  相似文献

通过面板数据固定效应模型,利用东北地区23个资源型地级城市1999-2012年的数据,分析了东北地区资源型城市资源诅咒效应的存在性与主要传导机制。结论显示东北地区资源型城市存在资源诅咒效应;物质资本投资对经济发展起到最为明显的促进作用,制造业投入和教育业投入也具有一定的促进作用,但作用不够显著。城市开放程度与经济发展之间呈现负相关关系,而城市类型与经济发展不存在明显相关关系。传导机制方面,资源诅咒效应主要通过抑制制造业发展、物质资本投入和教育业投入来阻碍经济增长,其中对制造业的负面影响是主要传导因素。煤炭和石油型城市体现出较为明显的人力资本挤出,而其他类城市传导机制作用则比较平均。  相似文献

We report the first well‐documented case of a South Island site where Mayor Island obsidian is not the dominant source represented. At the Pūrākaunui site (I44/21), located in coastal Otago, we find that most obsidians come from the Taupo Volcanic Zone, including sources near Lake Taupo (52%) and Rotorua (27.7 %). A small proportion of the collection comes from Mayor Island (10.8%) and the Coromandel Peninsula (9.5%) obsidian. The results point to early effects of regionalisation in source exploitation on the South Island.  相似文献
