As alarming as the climatic challenges posed to the nation have been, India is still found struggling to find the right laws to fight climate change, experts say.

POLLUTION PERIL

India witnessed a challenging year in terms of its environmental conditions, starting the year with a title, the capital city New Delhi earned last year -- the world's most polluted city according to the World Health Organisation --- which it retained this year as well. Delhi and cities surrounding it have surpassed the pollution levels of Beijing, which was the most polluted in the world until Delhi took its spot.

Pollution surfaced in unexpected ways -- like a lake in Bengaluru turning toxic and frothy with the industrial pollutants being mixed with the water. This incident caught not just national attention but that of the whole world.

The country's northern part was known to have exceeded pollution levels at many times of the year, which should have triggered a 'red alert' had it been in another country, according to environment body Greenpeace. "If India had an air quality monitoring system as robust as that of Beijing, a large portion of north India would have been on red alert for as many as 33 days," the NGO said recently, pointing to the necessity to establish stronger air monitoring systems across the country.

Even before the start of winter, which usually greets the northern states with hazy skies and smog covered days, the entire belt of Punjab, Haryana, Delhi and Chandigarh choked in smoke due to the paddy field fires -- the smoke which affected the country's climate even later for weeks, according to environmentalists.

But, according to Delhi-based environmentalist Vikrant Tongad, the year also saw the issue of air pollution being heard on a national and global level.

AN ACTIVE INDIA

Tongad said India never had such an "active" stance at the crucial UN Climate Change Conference, in standing up for the developing countries, as it had this year at the 21st Conference of Parties (CoP 21) held in Paris, he said. There are however some gaps in the deal signed, he added.

India, which had committed to cut its greenhouse emissions up to 35 percent by 2030, also pioneered the alliance of 120-odd nations to form the grand solar alliance, a move to harness solar energy better. India also bore a stern face in saying that the developed nations must contribute their part to reducing emissions and raising $100 billion a year to help developing ones.

CHENNAI FLOODS

These rains, which lasted for over a week, lashed Chennai and other areas of Tamil Nadu and Andhra Pradesh. Besides drowning a major portion of Chennai in flood water, many parts of Tamil Nadu were severely affected due to flooding. These rains, which were the heaviest Tamil Nadu received in over a century left at least 169 people dead in the state, and 54 dead in Andhra Pradesh. With public transport, residences, office buildings and crops affected, Tamil Nadu has been struggling to get life back to normalcy.

Union Minister for Forests, Environment and Climate Change Prakash Javadekar termed the floods as "not a part of climate change" and said that they were a "localised event" and a "natural calamity", which the environmental groups rejected. According to CSE, "unregulated urbanisation and climate change-induced extreme weather" were the reason behind the flood crisis in Tamil Nadu and other states.

COMMENDABLE STAND

The Supreme Court's recent decision to ban diesel vehicle registrations in the National Capital Region for three months and surrounding towns is also a much needed move, environment groups said.

Following the Delhi High Court's orders, the Delhi government undertook the initiative in the capital to ration road space, allowing even and odd numbered vehicles to ply only on alternative days. But an initiative like this needs to be thought through, as it could lead to the people going for a second car, the National Green Tribunal said.IANS
