“As winter approaches each year, a haze of toxic smog envelopes vast swaths of northern India, including the capital New Delhi, forcing authorities to shut schools and restrict the use of private vehicles. Unlike southern parts of the country, most arid regions of northern India, including New Delhi, struggle with dust, a common air pollutant. Environmental experts say New Delhi’s topography hobbles efforts by authorities to stave off the spike in pollution. In recent years, the problem has been exacerbated by the burning of crop residues in Punjab and Haryana states, part of the farm belt that borders New Delhi. Relatively prosperous farmers from Punjab and Haryana, India’s grain bowl, have started using mechanised harvesters to gather the rice crop, partly to overcome the problem of rising labour costs.” SOURCE: Al Jazeera
Mexico City has a reputation for horrible air pollution–and rightfully so–but Delhi’s air pollution is worse and this year it is off the charts. Much of India faces air pollution problems, but northern India, and especially Delhi sees the convergence of urban, agricultural, demographic, and environmental factors to exacerbate the problems. Geographic problems are often intertwined and is a good issue to use a S.P.E.E.D. or E.S.P.N. activity.
