With a clear focus on expansion of Metro Rail and bus services through Central funding, Budget 2021 has recognised a core component of urbanisation.
Clean and Green mass mobility
Comfortable, safe and affordable commuting has well-recognised multiplier effects for the economy and more generally for public health, although COVID-19 has had the perverse effect of driving people away to the safety of personal car and two-wheeler bubbles.

California (USA) is facing sprawling wildfires destroying more than 400,000 acres of forests in Northern and Central California.
Reasons for California’s Wildfires:
Climate: California, like much of the West, gets most of its moisture in the fall and winter. Its vegetation then stays dry throughout the summer because of a lack of rainfall and warmer temperatures, which ultimately serves as ignition for fires.
However with global warmin

Sea Level Rise: Its impact
GS-PAPER-1 Geography: Oceanography (PT-MAINS)
Recently, a study in journal Scientific reports made predictions that a large population and assets will be globally affected as a consequence of Sea Level Rise (SLR).
SLR is a consequence of climate change, which is predicted to increase coastal flooding by 2100.
The global population potentially exposed to episodic coastal flooding will increase from 128-171 million to 176-287 million by 2100

GS-PAPER-1 Geography – Urbanization
The Covid-19 pandemic has proved that the Indian cities are overburdened and underprepared to provide guaranteed social protection to millions of migrant workers. Due to denial of access to adequate food and nutrition, livelihood, housing and basic amenities like water and sanitation facilities, there has been an exodus of migrant labourers from urban to rural areas.
Further, with over 90% of the population work

Researchers have recently studied the formation of Venus’ ring-shaped volcanic structures called “Coronae”. They are formed by plumes of molten rock rising from the mantle up through the crust.
This process is similar to how Earth’s volcanos function. Interestingly, most of Earth’s volcanism occurs along the boundaries of tectonic plates, but modern Venus doesn’t seem to possess tectonic plates. They identified three dozen features on Venus

Social Security Number for Migrants
GS-Paper-3 Economic development (Mains)
The Parliamentary Standing Committee on Labour has recommended that the government introduce a social security number for migrant workers, especially those working in the unorganised sectors which are beyond the purview of the labour laws.
Background: The Ministry of Labour and Employment was unable to give any concrete figures on the number of migrant workers. However, the off

GS-Paper-1 Geography- Earthquake (PT)
According to a recently published study, researchers have developed a new way to improve the prediction of earthquakes.
Vibrations from an earthquake are categorised as P (primary) and S (secondary) waves. They travel through the Earth in different ways and at different speeds. They can be detected and analysed.

Assam’s Flood and Management
GS-PAPER -1 Geography – Flood Management
The recent flood in Assam has led to heavy casualties, displacement of peoples and animals and destruction of property and environment. It has also led to inundation of 80% of the area of Kaziranga National Park.
Reason behind Floods:
Ill-maintained or poorly constructed river embankments are the main reason behind the flooding. One major feature of flood management in Assam is total depe

Previously unknown faults at the foot of the Himalaya discovered
Data from an oil and gas exploration company has now helped geologists discover a series of faults at the foot of the Himalaya.
Sesimic exploration data
The team looked at seismic reflection data, which are routinely collected by exploration companies looking for oil and gas.
In this method, seismic waves are produced by small explosions at multiple sources, and many recorders called geophones record

Forest Fires in India
According to the report of the Forest Survey of India, between 2003–2017, a total of 5,20,861 active forest fire events were detected in India. About 54% of the forest cover in India is exposed to occasional fire.
Most fire prone regions - Northeast India, Madhya Pradesh, Odisha, Chhattisgarh, Himachal Pradesh and Uttarakhand. Western Himalaya have shown a sharp increase of carbon monoxide, nitrogen oxides and ozone during high fire activity perio
