The Individual

In this paper we investigate how well residents of the Andaman coast in Phang Nga province, Thailand, are prepared for earthquakes and tsunami. It is hypothesized that formal education can promote disaster preparedness because education enhances individual cognitive and learning skills, as well as access to information. A survey was conducted of 557 households in the areas that received tsunami warnings following the Indian Ocean earthquakes on 11 April 2012. Interviews were carried out during the period of numerous aftershocks, which put residents in the region on high alert. The respondents were asked what emergency preparedness measures they had taken following the 11 April earthquakes. Using the partial proportional odds model, the paper investigates determinants of personal disaster preparedness measured as the number of preparedness actions taken. Controlling for village effects, we find that formal education, measured at the individual, household, and community levels, has a positive relationship with taking preparedness measures. For the survey group without past disaster experience, the education level of household members is positively related to disaster preparedness. The findings also show that disaster related training is most effective for individuals with high educational attainment. Furthermore, living in a community with a higher proportion of women who have at least a secondary education increases the likelihood of disaster preparedness. In conclusion, we found that formal education can increase disaster preparedness and reduce vulnerability to natural hazards.

Abstract. The formation of a river of smoke crossing southern Africa is investigated during the Aerosols, Radiation and Clouds in southern Africa (AEROCLO-sA) campaign in September 2017. A complementary set of global and mesoscale numerical simulations as well as ground-based, airborne and space-borne observations of the dynamics, thermodynamics and composition of the atmosphere are used to characterize the river of smoke in terms of timing and vertical extent of the biomass burning aerosol (BBA) layer. The study area was under the synoptic influence of a coastal low rooted in a tropical easterly wave, a high-pressure system over the continent and westerly waves in mid-latitudes, one of which had an embedded cut-off low (CoL). The coastal low interacted with the second of two approaching westerly waves and ultimately formed a mid-level temperate tropical trough (TTT). The TTT created the fast moving air mass transported to the southwestern Indian Ocean as a river of smoke. The CoL, which developed and intensified in the upper levels associated with the first (easternmost) westerly wave, remained stationary above northern Namibia prior to the formation of the TTT and was responsible for the thickening of the BBA layer. This shows that the evolution of the river of smoke is very much tied to the evolution of the TTT while its vertical extent is related to the presence of the CoL. The mechanisms by which the CoL, observed over Namibia in the entrance region of the river of smoke, influences the vertical structure of the BBA layer is mainly associated with the ascending motion above the BBA layer. In the presence of the CoL, the top of the BBA layer over northern Namibia reaches altitudes above 8 km. This is much higher than the average height of the top of the BBA layer over the regions where the smoke comes from (Angola, Zambia, Zimbabwe, Mozambique) which is 5 to 6 km. The results suggest that the interaction between the TTTs and the CoLs which form during the winter may have a role in promoting the transport of BBA from fire-prone regions in the tropical band to the temperate mid-latitudes and southwestern Indian Ocean.

This chapter breaks down the artificial historiographical and archival dichotomy between ‘east and west’ by exposing the multiple and intricate connections that facilitated the systematic transfer of people, capital and goods between the Atlantic and Indian Ocean worlds. It will suggest that if we reorient our gaze from the economic structures of slavery and focus instead upon the family as a lens through which to explore Britain’s imperial engagement during this period, it is possible to reveal a far more interconnected and intimate vision of empire than is often credited. It will offer both a qualitative and quantitative survey of the scope of connections between the Caribbean, Britain and East India Company, alongside a consideration of how the structure of the archive can be negotiated in order to explore these questions. Finally, to provide substance and depth to these claims the chapter will offer a detailed case study of the Martins of Antigua.

This chapter takes a stock taking exercise of the history writing on Gujarat and Indian maritime history over the last five decades. It identifies the major shifts and emphases that mark the nature of historical knowledge. What these hold for the discipline of history in general and how these inflect the case study of Gujarat in particular are examined. The intention of such a stock taking exercise is also to consider the importance of recovering and reading new and local archives and of incorporating new methods into standard historical work. The author also explores the most significant shifts that have emerged in the recent historiography of the Indian Ocean and of maritime Gujarat: study of law and piracy and Muslim seafaring and sailing practices in the western Indian Ocean.
