Geospatial technologies are central to spatial decision making and governance, but gaining equitable access to these is still difficult for traditionally marginalized communities. We contend that the dominance of proprietary GIS software has contributed to this digital divide, as these are inherently disempowering to marginalized social groups. Their high purchasing cost and licensing fees pose access barriers to resource‐poor citizens. Design of proprietary software may also not be appropriate for marginalized groups who are neither trained in GIS, nor represent the needs of dominant market base. Therefore, “free and open source software for geospatial” (FOSS4G) and open GIS provide new opportunities in democratizing GIS, as these are open code and free of purchasing and licensing costs. This paper aims to discuss the role of open GIS in advancing the goals of public participation GIS (PPGIS). We first discuss the origins of the FOSS movement, and explore the ways it has shaped the FOSS4G and open GIS movements. Next, we examine how a community information system built with open GIS software is being successfully utilized by an environmental organization in Milwaukee, to contest urban poverty. Our research demonstrates that open source GIS offers unique opportunities in advancing PPGIS research and practice. 相似文献

Implications of climate change for glacier tourism 总被引:2,自引:0,他引:2

For more than 100 years, the Fox and Franz Josef Glaciers in Westland Tai Poutini National Park have attracted thousands of tourists annually and have emerged as iconic destinations in New Zealand. However, in recent years, the recession of both glaciers has been increasingly rapid and the impacts on, and implications for, visitor experiences in these settings remain relatively unexplored. A mixed-method approach was adopted to investigate visitor experiences and stakeholder perspectives through an assessment of climate-related changes on tourism at the glaciers in Westland Tai Poutini National Park. The bio-physical conditions at both the Franz Josef and Fox Glaciers were reviewed in order to assess the magnitude and rate of retreat. Perceptions of climate change risk and awareness of impacts in the National Park were assessed through stakeholder interviews (n = 13) and a visitor survey (n = 500) was used to better understand how impacts at these sites have affected and may continue to affect visitor experiences. Research results were reported to local communities via a series of public talks. Results revealed the fundamental importance of viewing the glaciers as a significant travel motive of visitors, suggesting that there is a ‘last chance’ dimension to their experience. Furthermore, the results demonstrate a high adaptive capacity of local tourism operators under rapidly changing environmental conditions. The implications of altered visitor experiences for tourism operators and protected area managers are discussed in light of these findings. 相似文献

The Pleistocene archaeological record of the Arabian Peninsula is increasingly recognized as being of great importance for resolving some of the major debates in hominin evolutionary studies. Though there has been an acceleration in the rate of fieldwork and discovery of archaeological sites in recent years, little is known about hominin occupations in the Pleistocene over vast areas of Arabia. Here we report on the identification of five new Middle Palaeolithic sites from the Nejd of central Arabia and the southern margins of the Nefud Desert to the north. The importance of these sites centers on their diversity in terms of landscape positions, raw materials used for lithic manufacture, and core reduction methods. Our findings indicate multiple hominin dispersals into Arabia and complex subsequent patterns of behavior and demography. 相似文献

The education sector has virtually disappeared from the Congolese state budget since the mid‐1980s. Yet schools have both managed to survive on school fees and to reproduce the public education sector, even though complete privatization would have been a realistic option. In this article, the authors understand this engagement with the state whilst simultaneously bending its rules as a negotiation strategy for better terms of inclusion in the state system. Different state actors cultivate their ‘own’ practical versions of official rules. In this way, they create space to respond to parents’ demand for education, to increase the number of teachers and their salaries far beyond what would otherwise have been possible, and to reproduce the system over time. One may wonder, however, whether the resilience of the sector in the face of the implosion of the state budget does not come at the price of building a more inclusive and higher quality education system. 相似文献
