复杂网络视角下的城市人流空间概念模型与研究框架

城市内人流特征研究一直是城市地理学和城市空间研究的重要领域之一.针对已有相关研究存在仅侧重于从人口规模、密度视角分析空间分布及格局特征,而对隐藏于空间分布背后,因人流动而建立的空间交互关系关注不足的问题.本文以流空间理论、复杂网络理论、空间行为交互理论为理论基础,立足基于流、网络剖析城市内部空间中各要素间的相互作用及关...

Measuring short-term population mobility among indigenous Australians: options and implications

"Despite the fact that indigenous Australians are known to be frequently mobile over the short term, statistical information regarding this population movement is grossly deficient.... This paper examines various means by which short-term population movement can be quantified to yield aggregate indicators of demographic impact. First, census data are used to establish the rate and pattern of inter-regional, short-term displacement. This reveals regional urban centres as net recipients of temporary residents while most rural areas experience temporary absenteeism. Secondly, results from household surveys are reported stressing the importance of including visitors to households in the estimation of service populations. Thirdly, administrative data on occupancy in urban hostels are used to derive indicators of the duration of movement."

Nature-dependent people: Mapping human direct use of nature for basic needs across the tropics

Understanding where people depend the most on natural resources for their basic human needs is crucial for planning conservation and development interventions. For some people, nature is a direct source of food, clean water, and energy through subsistence uses. However, a high direct dependency on nature for basic needs makes people particularly sensitive to changes in climate, land cover, and land tenure. Based on more than 5 million household interviews conducted in 85 tropical countries, we identified where people highly depend on nature for their basic needs. Our results show that 1.2 billion people, or 30% of the population across tropical countries, are highly dependent on nature. In places where people highly depend on nature for their basic needs, nature-based strategies that protect, restore or sustainably manage ecosystems must be carefully designed to promote inclusive human development alongside environmental benefits.     

The Drivers of Market Integration Among Indigenous Peoples: Evidence From the Ecuadorian Amazon

Knowledge of the driving forces behind indigenous participation in the market is essential for practitioners intending to integrate conservation and development policies in indigenous territories. Nevertheless, empirical research on the determinants of market integration among indigenous peoples is still scarce. This article uses household survey data and multivariate techniques to examine the drivers of market integration among indigenous groups in the Ecuadorian Amazon. We use multiple measures of market integration, including the sale of crops, timber, and wildlife; the use of credit; and participation in wage labor. The results show that the way in which indigenous peoples integrate into the market depends on their endowments of human, financial, and physical capital. More educated households are able to engage in commercial agriculture and nonagricultural wage work, whereas uneducated poor households in communities in conflict with outsiders are pushed to engage in poorly paid agricultural wage work and (often illegal) timber operations.     

Mapping urban Māori: A population‐based study of Māori heterogeneity

Urban Māori is a term that describes indigenous people in Aotearoa New Zealand living in urban environments. It includes Māori who hold traditional authority over land (mana whenua) and Māori who have moved away from their traditional homes (mātāwaka). This article describes the heterogeneity of the urban Māori population through the spatial analysis of iwi (tribal) census data for four urban centres. The results show complex variation in the distribution of mana whenua and mātāwaka populations and help to inform a discussion about the rights and interests of all urban Māori in the development and planning of cities, and subsequent policy responses.     

Kāhuli: Uncovering Indigenous Ecological Knowledge to Conserve Endangered Hawaiian Land Snails

Indigenous knowledge is a multilayered knowledge system that can inform contemporary management in both natural observations and cultural value. Centuries old observations preserved within song, chant, and story has been globally recognized as a resource to integrate with conservation efforts for endangered species. In the case of the endemic land snails, kāhuli, of the Hawaiian archipelago, there is a prominent cultural presence preserved in oral tradition and written records in 19th and early 20th century’s Hawaiian language newspapers. As we witness the dramatic decimation of one of the greatest models of species radiation, the unveiling of the repositories of indigenous knowledge is crucial for conservation of these endemic land snails. This paper reports on indigenous knowledge that informs about the cultural significance (i.e., poetic device, metaphorical role, importance to hula) and ecology of kāhuli, and how indigenous knowledge can contribute to conservation efforts of rare and endangered species.     

Moments in everyday/distant geopolitics: Young people’s fears and hopes

The everyday implications of a volatile geopolitical climate are increasingly recognised, but far less is known about how people’s emotional geographies are affected by geopolitical change. This paper offers a critical examination of how some young people in different parts of the world navigate fears and hopes that might be considered ‘global’ in nature, and those that might be considered ‘everyday’. We report from participatory research conducted with young people from a range of ethnic and cultural backgrounds living in New Zealand and the United Kingdom. We examine how personal fears and hopes intersect with wider anxieties about youth, urban crime and terrorism. The research suggests that global-everyday emotions are not separated out in young people’s analyses. They are critically reflexive about wider discourses of fear, while undertaking the day to day business of navigating what are sometimes challenging emotional topographies.
