Changes in global urbanization and emerging patterns of disaster losses suggest that it may now be time to refocus the hazards research agenda on problems of very large cities. The resolution of urban disaster issues will require development of new collaborative strategies between victims, researchers, managers, policy makers and stakeholders in the hazards community and their counterparts in other urban interest groups. The experience of megacities in the United States and elsewhere that have been affected by recent major disasters and continuing hazards is examined to identify opportunities for initiating new policies and programs. Implications for hazard research and the concept of urban sustainability are noted.

This paper considers some significant questions in geography and cognate fields about the roles of maps in the information age. Most maps are now digital products, offering immersive environments for user involvement. The increasingly networked digital distribution of geographic information in consumer-orientated cartographic representations leads to substantial changes how people individually and collaboratively experience and produce space and place. This article focuses on the ongoing metamorphosis arising through geobrowsing, the media-based flexible production of geographic knowledge through interactive maps. Drawing on work in media studies influenced by the so-called spatial turn—the rediscovering of geography-related questions in the social sciences and humanities, after modernism’s claimed prioritization of time and history (Soja in Postmodern Geographies. The reassertion of space in critical social theory, London, 1989; Jameson in Postmodernism, or, the cultural logic of late capitalism, Duke University Press, Durham, 1991)—this paper develops a theoretical framework built on the dynamic networked geomedial action spaces concept to understand the changing roles of information age maps as imagined materialist spaces for the experience and production of space—ultimately a medial turn. Following this concept, maps change from offering static and non-interactive frames of geographic reference for the production of space and place and as geomedia support a veritable infinity of interactive and map-based activities. Geobrowsing facilitates some new modes of geographic interactions that move from logocentric engagements with static maps to egocentric dynamic interactions with code-based elements of geomedial action spaces. Google Earth and similar geomedia facilitate maps that become intrinsic to a growing number of social action spaces and alter the experience and production of space and place.

While botanists, archaeologists, historians and linguists have contributed to the debate on the origin of the coconut pollen analysts have been silent. This article attempts to integrate the results of recent palaeoecological research with findings from the other disciplines.

The scholarship and discussion on urbanization and urbanism are restricted to the exploration of a few metropolitans and global cities. In this way, especially in India, several cities and towns do not fit into the understanding of knowledge produced from metropolitan or large cities. Taking the case of Dharamshala a small town in the Western Himalayas, this paper discusses how debate and conceptualization of urban processes, level of urbanization and scale of economies bypass thousands of small towns not only in India but across the global South. The paper draws attention to the categorization of the urban into small and big, metropolitan and non-metropolitan, unable to provide a comprehensive theory or concept to conceptualize activities and processes that coexist in binaries. Employing an ethnographic approach it discusses the ambiguous statistical criteria, infrastructural facilities, social and cultural dynamics, informality and illegality of Dharamshala. Building on this, the paper asserts that small towns and big cities have a lot of similarities in processes and activities, they may be different from each other at the level of size and scale. Drawing any kind of hierarchy among cities and towns that have the foundation in size (population and geographical) and scale (economies) and positioning them in ‘subaltern’ positions does not produce a comprehensive framework nor contribute to Southern urban theory but position small towns in between position of metropolitan’s cities and urban theories. Noting such debates and discussions, the contribution opens a fresh perspective to study small towns beyond their size and scale and focuses on the processes and activities that contribute to an understanding of Indian urban transition, thereby expanding Southern urban theories.

Islanders of the Torres Strait are originally skilled seamen. They have rich and correct knowledge about the physical circumstances of the sea, and of the ecological conditions of the maritime resources. The strait itself is the best fishing ground of natural pearl throughout the Pacific waters, then, pearl-seekers came from Sydney and pearls were sold even in London. Of course, Islanders were employed as labourers of diver-boats, on which they made intimate relation to Japanese divers who had excellent ability of diving and pearl-collecting. After World War II, new marine industry was introduced by Japanese, that is, pearl-culturing. Australia-Japan joint enterprises settled their pearl-farms in the strait, and Islanders found their good job with desirable incomes there. Moreover, they are getting some special technics of sea affairs in this industry. Author explains the cultural change of Islanders' society concerned with pearl-culturing in these decades.

Transformative disaster resilience in times of climate change underscores the importance of reflexive governance, facilitation of socio-technical advancement, co-creation of knowledge, and innovative and bottom-up approaches. However, implementing these capacity-building processes by relying on census-based datasets and nomothetic (or top-down) approaches remains challenging for many jurisdictions. Web 2.0 knowledge sharing via online social networks, whereas, provides a unique opportunity and valuable data sources to complement existing approaches, understand dynamics within large communities of individuals, and incorporate collective intelligence into disaster resilience studies. Using Twitter data (passive crowdsourcing) and an online survey, this study draws on the wisdom of crowds and public judgment in near-real-time disaster phases when the flood disaster hit Germany in July 2021. Latent Dirichlet Allocation, an unsupervised machine learning technique for Topic Modeling, was applied to the corpora of two data sources to identify topics associated with different disaster phases. In addition to semantic (textual) analysis, spatiotemporal patterns of online disaster communication were analyzed to determine the contribution patterns associated with the affected areas. Finally, the extracted topics discussed online were compiled into five themes related to disaster resilience capacities (preventive, anticipative, absorptive, adaptive, and transformative). The near-real-time collective sensing approach reflected optimized diversity and a spectrum of people’s experiences and knowledge regarding flooding disasters and highlighted communities’ sociocultural characteristics. This bottom-up approach could be an innovative alternative to traditional participatory techniques of organizing meetings and workshops for situational analysis and timely unfolding of such events at a fraction of the cost to inform disaster resilience initiatives.
