Owing to low visibility, the railways delayed Puri-New Delhi Purushottam Express, JayNagar-New Delhi Swatantra Senani express , New Jalpaiguri-New Delhi Express by 5 hours, 4 hours and 2 hours 30 minutes respectively.
People residing in Delhi have been advised to restrict outdoor activities, especially those having breathing issues. While light showers early this week brought brief respite, the situation still remains bleak.
Apart from vehicular and industrial pollution, practices like residue crop burning and use of bio-mass, such as cow-dung, wood and coal also aided to air pollution. With a large population relying on these practices, efforts to curb the menace of pollution need stringent measures.
On the contrary, India's neighbour, China is making progress in this regard and has seen significant improvement. In 2013, the Chinese government identified the major pollution regions such as Hebei, Tianjin, and Beijing and set up specific pollution reduction targets and rolled out ten measures for the proper implementations of the regional action plans. Moreover, the government also fixed the quota of a total number of vehicles in its state to 6 million in 2017. From the past couple of years, as much as 4022 hectares of land has been transformed into green spaces. It also has a target of reducing coal consumption by 80 per cent by 2020.
