‘Coastal areas prone to climate change implications’

KARACHI: Pakistan is a country with ecologically and geographically diverse features and having large populations living along coastal belts, river deltas and arid regions, which are at direct risk of flash flooding, sea level rise and droughts caused by climate change, said a research study conducted by Imtiaz Ali at Quaid-e-Azam University.

It said, “Climate change raises fears of its tremendous socio-economic and environmental impacts. Pakistan is frequently exposed to natural calamities like floods, droughts, earthquakes and cyclones. Coastal areas are among the most sensitive aspect to climate change in Pakistan. Projected impacts are included rise of sea level, stronger tropical cyclones, soaring sea surface temperature and acidification of surface water. The repercussions of these changes on coastal ecosystem and communities could be threatening the health, livelihood, destroying infrastructure and displacing millions of population. Mounting sea levels can also exacerbate saltwater intrusion into the rivers and aquifers that furnish freshwater to coastal settlements.”

The report said that the Himalayan-Karakoram-Hindukush (HHK) glaciers are the third largest ice mass on the earth, after the Arctic and the Antarctic. It is reported all over the world that glaciers are receding since the last century, those in the HHK region are found to be melting faster than any others. The alarming situation is that if the present speed of recession continues, the HHK glaciers might become extinct by 2035. The excess of melting of HHK glaciers are expected to cause flooding in the Indus and its tributaries for the coming two to three decades than it will be preceded by reduced river flows as the glaciers retreat, it added.

The Indus River is the only source of Pakistan’s water resources and it supplies water for agriculture and hydroelectricity. Any interruption to this hydrological system will have disastrous impacts on Pakistan’s economic and social life, the research warned.

The research said, “Pakistan is a victim of horrible incidents of climate change. Though Pakistan’s contribution at the global average is minuscule, it is 12th most vulnerable to climate change in the world. Climate change affects countries more, which lies in the temperate zone-below the line of equator. Pakistan lies in the temperate zone, because of this, Pakistan is very prone to droughts, low precipitation in lower parts and heavy rainfall in upper parts, cyclones, heat waves and water shortage for agriculture and drinking purpose are main repercussions of climate change. Its geographical location, landscape and climate is particularly vulnerable to climate change.”

As Pakistan is a developing country, its 30 percent population is living below poverty line and its technical and financial capacity is insufficient to face the challenges of climate change, the research warned. Pakistan’s vulnerability to climate change comes from geographical location, physical landscape, natural climate system, endemic poverty, outdated disaster management infrastructure, poor technical and resource capabilities. By virtue of its natural features and system’s incapacities, the most vulnerable sectors and aspects to climate change in Pakistan is agriculture sector. “The IPCC projected that average world surface temperature would increase from 1.4 degrees Centigrade to 5.8 degrees Centigrade over the course of the 21st century. It is evident that the alteration in the planet’s ecological, biological and geological system will not only continue but also intensify.”

“This exposure to danger is predicted to exacerbate with imminent impact of climate change. There has been escalation in the incidence, intensity and frequency in the climatic events in Pakistan, which are more extreme and heavier precipitation that happened as in 2010 and three successive years. The deluge of 2010 has broken all past records of extent and force. It affected more than 20 million population, ich is more than those hit by Tsunami in 2004, earthquake in 2005 in Pakistan and 2009 in Haiti,” the research concluded.
