Urbanization, their problems and their remedies.
Cities
need a sustainable transport update
Context: Bengaluru’s
never-ending traffic jam and Delhi’s pollution levels has made it resoundingly
clear that the present model of urban transport is unsustainable, and the only
way out of the cycle—of rising incomes and more wheels on the road—is an
efficient public transport alternative.
What
made the present model of urban public transport unsustainable?
City-development
plans have failed to create the right incentives, as is borne out by the
preference for private transport. The problem starts with the way cities are
governed in India. The lack of adequate devolution as per the Constitution
(74th Amendment) Act, 1992, and consequently, effective power vested in a
city-level governance mechanism, exacts a heavy toll.
What
needs to be done?
The
urban transport policy must rethink the hierarchy of needs; pedestrians and
cyclists must be on top, followed by buses and then motor vehicles.
Metros: The
government must pivot the policy to delivering reliable public transport. The
metro project is a step in the right direction, but it needs complementary
changes that improve the citizens’ experience. The metro system needs a bus
system to provide last-mile connectivity.
Buses: If
people have to take buses, they need pedestrian paths to walk on the roads. The
bus system also needs to be reliable. A centralized monitoring system that
tracks buses using GPS is needed. Such system monitors driving speed and
ensures that they stop at every bus stop.
Change
in government’s attitude: The government must
resist using attractive-sounding propositions, like pushing electric and hybrid
buses, to give the impression that there is political will to improve urban
transport. Changing the fuel of the bus will reduce emissions, but there will be
dramatically bigger gains if we are able to prompt even a quarter of the
private vehicle-using population to use public transport.
Maintenance: India
has plenty of assets that are decaying due to poor maintenance. Policymakers
will do well to make space for depreciation accounts in their budgets to pay
for maintenance and replacement of public assets.
Way
ahead:
India
is a growing economy, and census data suggests that only 31% of the population
lives in urban centres. Another 300 million people will be added by 2050 and
the planning for carrying those people in our cities must begin now. Public
transport can easily be the cheaper, faster and economical alternative if
policymakers plan for tomorrow’s problems today.

Pradhan
Mantri Urja Ganga
Context: State-run
gas utility GAIL India has placed orders for another 400-km of pipeline of the
ambitious Pradhan Mantri Urja Ganga natural gas pipeline project that will take
the fuel to eastern India. With these awards, pipe supply orders for 2,100 km
of the Jagdishpur-Haldia & Bokaro-Dhamra Natural Gas Pipeline (JHBDPL)
project have been placed. Also, 1,700 km of line laying orders have been
placed.
About
the Pradhan Mantri Urja Ganga project:
The
gas pipeline project aims to provide piped cooking gas to residents of Varanasi
and later to millions of people in states like Bihar, Jharkhand, West Bengal
and Odisha.
§ From
Varanasi’s perspective, an 800-km long MDPI pipeline will be laid and 50,000
households and 20,000 vehicles will get PNG and CNG gas respectively. The
government estimates that around 5 lakh gas cylinders will be sent at rural
areas annually.
§ According
to GAIL, with the Urja Ganga project, 20 lakh households will get PNG
connections. The project is said to be a major step towards collective growth
and development of the Eastern region of India.
§ GAIL
has built a network of trunk pipelines covering the length of around 11,000 km.
With Urja Ganga project, this number will further increase by 2540 km.

Ujh
Project
Context: In
a bid to fast track utilization of India’s rights under Indus Waters Treaty,
the DPR of Ujh Project was recently submitted by Central Water Commission to
the Jammu & Kashmir government. The DPR will help India to utilize a part
of the flow that presently goes across border unutilized.
About
the Ujh project:
The
Ujh project is a step towards India’s utilisation of waters of the Indus and
its tributaries in keeping with its rights under the treaty. The project, which
is to come up in Kathua district, will store around 0.65 million acre feet
(MAF) of water from Ujh (a tributary of Ravi) to irrigate
30,000 hectares and produce over 200 MW of power.
About
the Indus water treaty:
Signed
in 1960 by then Prime Minister Jawaharlal Nehru and then Pakistan President
Ayub Khan, the treaty allocates 80% of water from the six-river Indus water
system to Pakistan. Under the treaty, control over six north Indian rivers were
divided between the two countries. India got control over the rivers Beas, Ravi
and Sutlej whereas Pakistan got control over Indus, Chenab and Jhelum.
Unique
features of the treaty:
Involvement
of the third party: This is a unique treaty
involving a third party. It was brokered by the World Bank.
Permanent
commission: A Permanent Indus
Commission was set up as a bilateral commission to implement and manage the
Treaty. The Commission solves disputes arising over water sharing.
Arbitration
mechanism: The Treaty also provides arbitration mechanism to solve
disputes amicably.

China’s
First Solar Highway
China
has constructed the country’s first solar highway, in which solar
panels are placed underneath transparent concrete.
About
the solar highway:
The
solar highway is a 2 km (1.2 mile) stretch of road located on the Jinan City
Expressway, and it’s divided into three layers. The see-through concrete
shields an array of solar panels of two sizes. Beneath the solar panels is a
layer that will keep them isolated from the damp ground.
The
expressway can handle 10 times more pressure than the normal asphalt variety
and in a year generate 1 million kWH of electricity, which will be used to
power street lights and a snow-melting system on the road. It’s also designed
to supply power to charging stations for electric vehicles, should those be
added in the future.
Facts
for Prelims:
China
is billing the project as the world’s first photovoltaic highway. In late 2016,
a village in France opened what it claimed was the world’s first solar-panel
road, running for about the same length as China’s new stretch though covering
about half the area. In 2014, the Netherlands built a bike path embedded with
solar panels.
Way
ahead:
Solar
roadways may have their critics (they are susceptible to being covered by dirt
and other debris), but as their efficiency and applications improve, they’re
sure to prove their value. And with EVs becoming more popular, the world’s
going to need more ways to keep their vehicles charged and ready to go.

Bio-CNG
Context:
To promote the use of clean fuel, the oil ministry plans to set up bio-CNG
(compressed natural gas) plants and allied infrastructure at a cost of Rs7,000
crore. The oil ministry will be working with state-run oil and gas retailers to
set up the plants over the next two years. The government’s plan is to make
India a gas-based economy.
What
is Bio- CNG?
Bio-CNG
is a purified form of biogas with over 95% pure methane gas. It is similar to
natural gas in its composition (97% methane) and energy potential. While
natural gas is a fossil fuel, bio-CNG is a renewable form of energy produced
from agricultural and food waste. Bio-CNG is being looked at as an
environment-friendly alternative to diesel.
How
is CNG generated from agricultural waste?
The
process of generating CNG from agricultural waste involves treating the waste
matter with a special bacterial solution, and then the gas which is generated
is cleaned and compressed so that it can be used in vehicles.
Benefits
of Bio- CNG:
The
cost of production of 1kg of bio-CNG could be Rs15-20, cheaper than CNG, petrol
and diesel. Besides, it will help in reducing the country’s import of diesel up
to 50%. It is also pollution free.
Background:
India
currently imports one-third of its energy requirement. The world’s
third-largest crude oil importer is targeting halving its energy import bill by
2030. The government aims to increase the contribution of gas in India’s energy
mix to 15% from the current 6.5%.

NASA’s
flying telescope
Context:
NASA’s flying observatory Sofia is preparing for its 2018 campaign, which will
include, among others, observations of celestial magnetic fields, star-forming
regions, comets and Saturn’s giant moon Titan. This will be the fourth year of
full operations for Sofia, short for Stratospheric Observatory for Infrared
Astronomy, with observations planned between February 2018 and January 2019.
Significance
of the observations:
Scientists
believe that the observatory’s investigations will help them understand how
magnetic fields affect the rate at which interstellar clouds condense to form
new stars. These observations could also help them learn whether the luminosity
of these active black holes is driven by star formation or accretion of
material onto the central black hole. Sofia will also conduct observations to
better understand how methane levels change with seasons on Mars.
About
Sofia:
What
is it? Sofia is a Boeing 747SP jetliner modified to carry a 100-inch diameter
telescope. It is a joint project of NASA and the German Aerospace Centre, DLR.
SOFIA is designed to observe the infrared universe.
SOFIA
studies many different kinds of astronomical objects and phenomena, but some of
the most interesting are:
§ Star
birth and death.
§ Formation
of new solar systems.
§ Identification
of complex molecules in space.
§ Planets,
comets and asteroids in our solar system.
§ Nebulae
and dust in galaxies (or, Ecosystems of galaxies).
§ Black
holes at the center of galaxies.
Why
does NASA need a flying telescope?
Water
vapor blocks infrared light energy and 99% of the world’s water vapor exists
below 39,000 feet. So, the higher altitude you fly, the drier it gets and the
more optimal it is for infrared observation.
