Salient Features of Indian Road Network and Highways

In India

About 65% of freight and 80% passenger traffic is carried by the roads.

  • National Highways constitute only about 1.7% of the road network but carry about 40% of the total road traffic.
  • Number of vehicles has been growing at an average pace of 10.16% per annum over the last five years. About 65% of freight and 80% passenger traffic is carried by the roads.

India has the second largest road network in the world, with over 3.314 million kms of roadways spread across the length and breadth of the country. The roads are primarily made of bitumen, with some Indian National Highways having concrete roads. The concept of expressway roads is also catching up in India, and the Mumbai – Pune expressway and Delhi Gurgaon expressway are the finest examples. Yamuna-expressway which connects Delhi to Agra is also good.

The history of roads in India takes you back to the Indus Valley Civilization, where street pavings were made for the first time in India. Around the 1st centuy, the Silk route was made which tremendously aided in trade across India. The medieval India saw the emergence of the Grand Trunk Road. The GT Road, as it is famously called, starts in Sonargaon near Dhaka in Bangladesh and ends at Peshawar in Pakistan and links some of the major cities in india from Kolkata to Amritsar.

The Indian roadways network ranks as the second biggest roadways network in the world. The road network of the country covers more than 2.059 million miles or 4.42 million kilometers. For every sq km of land, there is 0.66 km of highways in the country.

The density of the highway network of India is somewhat more as compared to the United States (0.65) and substantially higher as compared to Brazil (0.20) and China (0.16).!!!!

Previously, India did not had funds fori ts road network. However, the scenario has changed in the past decades. The Government of India in collaboration with a number of private players is taking groundbreaking endeavours for the road transportation system of the nation.

Till date, some of the important plans that have been put into operation include names like the Yamuna Expressway, National Highways Development Project, and the Mumbai-Pune Expressway.

According to the data furnished in 2002, just 47.3% of the Indian roadways network comprised paved roads.

Neanderthals and Humans may have Coexisted

A trove of Neanderthal fossils including bones of children and adults, discovered in a cave in Greece suggests that the area may have been a key crossroad for ancient humans.

The fossils suggests Neanderthals and humans may have at least had the opportunity to interact, or cross paths, there, the researchers added.

Neanderthals were the closest  relatives of modern humans, apparently even occasionally interbreeding with our ancestors. Neanderthals entered Europe before modern humans, and may have lasted there until about 35,000 years ago.

Neanderthals are classified either as a subspecies of Homo sapiens (Homo sapiens neanderthalensis) or as a separate species of the same genus (Homo neanderthalensis). The first humans with proto-Neanderthal traits are believed to have existed in Europe as early as 600,000–350,000 years ago.

The species is named after the site of its first discovery, about 12 km (7.5 mi) east of Düsseldorf, Germany, in the Feldhofer Cave in the river Düssel’s Neander valley named for Joachim Neander, a 17th-century German pastor and hymnist. Neander’s own name was a Greek translation of the German Neumann (lit. “New man”). Thal is the older spelling of Tal (both with the same pronunciation), the German word for ‘valley’ (cognate with English dale).

Comparison of the DNA of Neanderthals and homo sapiens suggests that they diverged from a common ancestor between 350,000 and 400,000 years ago. This ancestor is not certain, but was probably Homo heidelbergensis (sometimes called homo rhodesiensis). Heidelbergensis originated between 800,000 and 1,300,000 years ago, and continued until about 200,000. It ranged over east and south Africa, Europe and west Asia. Between 350,000 and 400,000 years ago the African branch is thought to have started evolving towards modern humans and the European branch towards Neanderthals. Scientists do not agree when Neanderthals can first be recognised in the fossil record, with dates ranging 200,000 and 300,000 years BP.

Recently a study has been able to accurately determine the age of the Neanderthal remains found in the El Sidrón cave (Asturias, Spain) for which previous studies had provided inexact measurements.

Climate change is allowing agriculture to boom. The Independent on Sunday reports 

Inside the Arctic Circle, a chef is growing the kind of vegetables and herbs – potatoes, thyme, tomatoes, green peppers – more fitted for a suburban garden in a temperate zone than a land of northern lights, glaciers and musk oxen. Some Inuit hunters are finding reindeer fatter than ever thanks to more grazing on this frozen tundra, and, for some, there is no longer a need to trek hours to find wild herbs.

This is climate change in Greenland, where locals say longer and warmer summers mean the country can grow the kind of crops unheard of years ago. “Things are just growing quicker,” said Kim Ernst, the Danish chef of Roklubben restaurant, nestled by a frozen lake near a former Cold War-era US military base. “Every year we try new things,” added Mr Ernst, who even…
