Lahore/New Delhi:Â From his office in the smog shrouded city of Lahore, environment official Saif Anjum pores over reams of pollution data and lists the actions being taken by Pakistanâs largest province to combat the toxic air. He said they have arrested hundreds of crop-burning farmers and closed construction sites and industrial furnaces.
But those efforts risk being for naught without collaboration with Pakistanâs nuclear-armed arch-rival India.
The neighbours are grappling with farmers burning fields on their respective sides of the Punjabâa fertile breadbasket region located in northwestern India and northeastern Pakistanâthat was torn in two by the partition of British India in 1947. Those fires, set to clear fields for the next crop, are worsening the deadly smog now choking the cities of Lahore and New Delhi.
âWe have a common enemy,â Anjum, a retired Pakistani army captain and secretary at Punjabâs Environment Protection Department, said in an interview on Monday. âWe have already requested the federal government for approaching the Indian side. Both sides need to work on it jointly, thereâs no other way.â
While Anjum said formal discussions had not yet been held between the two neighbours, in a tweet last week the Punjab government in Pakistan said it had banned stubble burning and said it hoped Punjab chief minister Amarinder Singh âtakes similar measures.â
Despite a bloody history, the fates of 1.5 billion people in both India and Pakistan are increasingly at risk from developing hazards such as air pollution, not just conventional security threats. Air pollution is estimated to kill more than half a million Indians and Pakistanis every year, while the World Bank has said environmental degradation costs India $80 billion annually.
There are some precedents to solving cross-border issues, such as a river sharing treaty, but India-Pakistan ties are at a low-ebb, while domestic political considerations in India might make collaboration with Pakistan is impossible.
The foreign ministries from both countries didnât respond to requests for comment.
âEnvironmental standards and climate change issues are new non-traditional security threats,â said Hina Lotia, the director of programmes at Leadership for Environment and Development Pakistan, an Islamabad-based think tank. âThese issues are not any less important than the traditional disputes and differences that bedevil our relationship.â
In recent weeks, toxic smog has shrouded north India and parts of Pakistan. New Delhi, whose chief minister shut schools and called the city a âgas chamber,â has generated global headlines for its air pollution.
But many other cities across north India and in Pakistan also have high pollution levels. Lahore, the capital of Pakistanâs Punjab, has been covered in smog for weeks that has led to cancelled and delayed flights, as well as pileups on highways. The World Health Organization said air pollution in 2012 caused 612,000 deaths in India, and almost 60,000 deaths in Pakistan.
The causes are complex and range from vehicle and industrial emissions to construction and road dust. But a large part of the problem is crop burning. Because of the short window of time between harvesting rice and planting wheat in the same soil, itâs cheaper and faster for farmers to set the crop residue on fire rather than cart it away. When millions do this, the deadly haze can be seen from Nasa satellites.
On the same day Punjabâs government reached across the border, a US state department official warned Congress about the lingering likelihood of a nuclear conflict breaking out between India and Pakistan.
âPolitics donât allow the two countries to partner on such initiatives, even in cases where each side faces the same dangerous threat,â said Michael Kugelman, a senior associate for South Asia at the Washington-based Woodrow Wilson Center.
But even if national governments arenât taking action, it makes sense for the two Punjab governments to coordinate policy, said Kartikeya Singh, who studies energy and sub-national governments at the Washington-based Center for Strategic and International Studies. âWhy shouldnât Punjab talk to Punjab?â he said.
Cross-border collaboration is possible on health matters, even if it is unlikely on military or territorial issues, said Ashok Swain, a professor of peace and conflict research at Swedenâs Uppsala University. India has been able to compartmentalize contentious aspects of its relationship with China, while moving forward on other issues such as trade, he said.
âItâs always easier for these contentious parties to agree on these types of issue which are environmentally critical,â he said.
While Delhiâs chief minister Arvind Kejriwal has blamed farmers in Punjab and Haryana, Singh of Punjab has called on Prime Minister Narendra Modi to take action.
In Pakistan, Punjab is dominated by the federally ruling Pakistan Muslim League-Nawaz, making anti-pollution measures easier to coordinate and impose across the province.
Yet actions from both governments will only slightly improve air pollution across the sub-continent due to the overall effects of climate change, said Qamar-uz-Zaman Chaudhry, the former head of the Pakistan Meteorological Department.
âCoordination will not drastically change the situation, but some improvements can be achieved,â he said from Islamabad. âRealistically both are suffering, so if they can cooperate that would be the ideal thing they can do.â
