Abstract: It is now widely acknowledged that when disasters occur, not all members of the ‘affected community’ are affected the same way. The earlier literature on gender and disasters over-emphasized women’s vulnerabilities in the aftermath of a disaster due to their care-giving roles. It did not consider the differential vulnerabilities of diverse groups of women based on their class, caste, race, age, occupation or sexual orientations. Similarly, men’s differential vulnerabilities were seldom discussed in the early literature on this subject. After disasters like the 2004 Tsunami and 2005 Hurricane Katrina however, the importance of the intersectionality of gender with race, occupation and class and other axes of social identity became more visible and discussed in the literature. This paper provides an overview of the literature on gender and disasters and calls for the need to nuance identity categories based on their intersectionality and multiplicity to achieve more sensitive and effective disaster responses.
Notwithstanding its polluting nature, coal remains the cheapest and most convenient fuel for meeting India’s energy needs. Since hydro power and nuclear power have safety issues, and green energy rema...
Abundant and cheap availability of domestic coal led India to follow a coal centric development path in the past. Given the current trends in production and consumption, India is expected to exhaust i...
Calving is when chunks of ice break off at the terminus, or end of a glacier. Ice breaks because the forward motion of a glacier makes the terminus unstable. Then glacial calving occurs at the coasts—these resulting chunks are called 'icebergs'.
Moraines are accumulation of rock debris (till) carried or deposited by a glacier. The material, which ranges in size from blocks or boulders (usually faceted or striated) to sand and clay, is unstratified when dropped by the glacier and shows no sorting or bedding.
A subglacial lake is a permanent lake under a glacier, typically an ice cap or ice sheet. Subglacial lakes are usually formed due to the action of geothermal activity or the pressure exerted by the overlaying ice.
A crevasse is a deep, wedge-shaped opening in a glacier or ice sheet. Crevasses usually form in the top 50 m of a glacier, where the ice is brittle. Below that, a glacier is less brittle and can slide over uneven surfaces without cracking. The inflexible upper portion may split as it moves over the changing landscape.
A drumlin is an oval or elongated hill believed to have been formed by the erstwhile streamlined movement of glacial ice sheets across rock debris, or till.
Glacier mass balance is the difference between accumulation and ablation of a glacier in terms of the difference in thickness of snow from the previous measurement.
The process by which a layer of ice builds up on solid objects that are exposed to freezing precipitation or to supercooled fog or cloud droplets. At the earth’s surface this frequently leads to the formation of ice glazes.
An ice core is a cylinder-shaped sample of ice drilled from a glacier. Ice core records provide the most direct and detailed way to investigate past climate and atmospheric conditions.
Antarctic Circumpolar Current, also called West Wind Drift, surface oceanic current encircling Antarctica and flowing from west to east. It is Earth’s largest ocean current with the volume of water transported said to be at least 25,000,000 cubic m.
An ice shelf is a thick mass of floating ice that is attached to land, formed from and fed by tongues of glaciers extending outward from the land into sheltered waters.
Permafrost is perennially frozen ground, a naturally occurring material with a temperature colder than 0 °C (32 °F) continuously for two or more years. Such a layer of frozen ground is designated exclusively on the basis of temperature.
When glaciers melt faster than they are replenished by precipitation, the total volume decreases. The glacier shrinks. This is called a glacial retreat. The glacier is not actually physically moving up, but only appears to do so.
Albedo is the fraction of light that is reflected by a body or surface. Ice and snow being white in colour exhibit high albedo, i.e. reflectance of solar heat.
The Antarctic Treaty is an agreement signed by 12 nations, in which Antarctic was made a demilitarised zone to be preserved for scientific research. The Treaty resulted from a conference in Washington, D.C.
Black Carbon is any of a group of intensely black, finely divided forms of amorphous carbon, usually obtained as soot from partial combustion of hydrocarbons. Their deposition on frozen matter can cause the matter to melt.
