India was a late starter in developing an early warning system for tsunamis. But ever since it became operational, the Indian Tsunami Warning System has developed into a world class platform to serve the entire Indian ocean region.
A tsunami early warning system is devised to detect tsunamis well in advance and issue timely warnings to prevent loss of life and damage. A tsunami early warning system is made up of two components, a network of sensors to detect tsunamis and a communication infrastructure to disseminate timely alarms for evacuation of people from coastal and low lying areas.
The December 26, 2004 earthquake and the subsequent tsunami exposed the vulnerability of the Indian coastline to oceanic hazards. Following the event, India started its own interim tsunami warning center in the first quarter of 2005 to issue tsunami bulletins generated from seismic information. The interim services were succeeded by setting up of a state-of-the-art Indian Tsunami Early Warning System (ITEWS) at the Indian National Centre for Ocean Information Services (INCOIS), Hyderabad, under the Earth System Sciences Organisation (ESSO), Government of India.
Modelling studies indicate that for Tsunami genic earthquakes occurring close to the Andaman and Nicobar Islands, the water arrival time is less than 30 minutes and for the Indian mainland the water arrival time is more than four hours. This means that the criteria to be adopted for issue of warnings need to be different for the islands and for the mainland.
Since immediate warnings need to be issued for Andaman and Nicobar islands, without enough time for confirmation of water levels, this might lead to false alarms. However, in the case of main- land, warnings are issued only upon confirmation of water levels. Hence, there is little chance of any false alarm.

Covid-19: Politics Of Knowledge, Public Health And The World Order
In the present era of a knowledge society, the world order will be shaped more than ever before by the politics of knowledge. In the post-CoVId world, public health knowledge is likely to be a significant contributor. This article briefly discusses the various contemporary public health approaches evident within the discipline: global health, community medicine and critical public health. Then it goes on to analyse country level policy approaches to the COVID-19 pandemic, delineating a tentative four-category typology, based on available information. Finally, it sets out the possible outcome indicators that should be used to assess the national responses.
WILD MEAT AND WET MARKETS: A GLOBAL DIALOGUE
Wet markets operate in most Asian countries including India. China reported its wet markets as the epicentre of the Covid-19 outbreak in Wuhan and also more recently in Beijing. These wet markets, a traditional part of popular local culture in Asian countries, are increasingly becoming a cause of concern for the international community and health practitioners across the globe. This article attempts to understand how global authorities and their Asian partners are looking to regulate these infamous wet markets to significantly lower the risk of viral and other pathogenic load from these unhygienic wet markets.
SEA WALL IN THE MALDIVES AND ITS SUSTAINABILITY
The Small Island developing states are particularly vulnerable to the peril of climate change. Sea level rise, increase in sea surface temperature, high incidences of drought and flood are some of the vulnerabilities that loom large over such island states.The republic of Maldives is one such example, which has been publicly advocating for the reduction in greenhouse gas emissions. Despite being one of the least contributors to such emissions, the Maldives faces the highest impact of global warming. Being one of the lowest-lying island nations, it has been undertaking various steps to curb the egregious impacts of environmental catastrophes.One of the response measures taken by the Maldives is the construction of seawalls. This article discusses this, while accenting the drawbacks and benefits associated with the approach.
TO PLUCK AT WILL: FRUIT TREES IN COMMON PROPERTY
Despite many governmental initiatives, malnutrition in India remains a major health challenge. There is a marked deficit of fruits in the diet of most Indians, consuming much lower than what is recommended by the World health organisation (Who). One of the reasons behind this is the high price of fruits and thus its inequitable access. As we prepare ourselves to live in a world marred by COVID-19 and a shrinking Indian economy, we must think of new ideas to manage access to food, especially micro nutrient rich fruits. This paper explores the possibility of planting endemic fruit trees in public spaces like roadsides and parks, that can help in increasing the consumption of fruits amongst the poor. It also attempts to analyse whether this can serve as a long term solution to bridge the gap between fruit production and consumption in India.
RESPONSIVE URBAN PLANNING: COVID-19 A TURNING POINT FOR REAL CHANGE IN INDIAN CITIES
The global challenge of COVID-19 is still unfurling. States are grappling to control its remorseless spread with varied success and its impact both on long and short-term scales are still being understood. However, a distinct urban bias in its spread across the globe and universal response of lockdown and social distancing for its control has brought pertinent questions to the fore. Urban planning and the future of our cities in terms of urban life and city form therefore needs to be revisited. In India, the exodus of migrant workers from its large cities has added yet another dimension to this challenge.

Understanding Caste and Class - Categories and Measurement
The caste has been a unique social institution in India. It has also emerged in a new form after the mandalisation of caste in the early 1990s resulting in the extension of reservation to Other Backward Classes (OBCs) in government jobs and also in admissions to colleges and universities. The relative size of population of various caste groups particularly of the OBCs is also a matter of debate. Census does not provide population data on OBCs, however, it is possible to assess it from nationally representative sample surveys. Further, the correspondence between caste categories and class has been a matter of debate. This paper presents an assessment of class within caste categories based on data from nationally representative sample surveys.
The Middle Class - As the Class of No Class
An attempt to understand some of the ambiguities around what it means to be middle class in India has been made in this paper. It also discusses the influence that the middle class supposedly has on Indian politics despite these uncertainties.
