Siwalik Hills A Storehouse Of Extinct Mammals
Geography and You|Issue 136 - 137, 2019
The Siwalik hills are known to be a storehouse of fossil mammals. The rocks entomb a variety of fossils of extinct mammals ranging in age from 16 to 6 million years. Important groups of mammals at various evolutionary stages which thrived during the deposition of the Siwalik rock strata are elephants, horses, cats, cattle, deer, giraffes, rats, pigs, hippopotamus, rhinoceroses and many others.

Siwalik Hills A Storehouse Of Extinct Mammals

The low hill ranges of ‘Siwalik’ exposed between the mighty Himalaya and the plains of the Indian subcontinent form the foothills of Himalaya. This range is about 2400 km long, from the Indus River in the west to the Brahmaputra River in the east, with a gap of 90 km between the Teesta and the Raidak rivers in West Bengal/ Assam. The width of the Siwalik hills varies from 1000 m to 5000 m with an elevation of 1500 m to 2000 m and supports a variety of fauna and flora. The term Siwalik (or Shiwalik) is considered to have originated from the Hindi and Nepali term 'Shivalik Parvat' and derived from the hills of the same name in Haridwar, Uttarakhand. Shivalik is said to mean 'tresses of Lord Shiva'. These hills are made up of clay, silt, sandstones, and conglomerates brought down between 16 million to 6 million years ago, by numerous fast-flowing rivers arising from the then rapidly rising mountain mass in the north.

The hills record the signatures of various episodes of the rise of the Himalaya. The Siwalik is composed of 5000-6000 m thick succession of sedimentary rocks of fluvial nature. Consequent to the rise of the Himalayan mountain chain, there seems to have been a progressive increase in moisture content and temperature, which helped support thick forest vegetation. These climatic conditions, therefore, helped the existing Siwalik fauna multiply rapidly and numerous forms of elephants (proboscides), horses (equids), cattle (bovids), pigs (suids), giraffes, apes, rhinos, deer, rats (rodents) and cats (carnivorous animals) thrived in large numbers.

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

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.
