Infrastructure including buildings, hotels, bridges and roads under the way of flood water was swept away leaving millions of people homeless. At least two million of land was ruined and one million livestock was vanished, which is vulnerable to malnutrition, food scarcity, economic issues and disease spread.
The most flood affected province is Sindh, Balochistan at 2nd, KPK at 3rd and South Punjab at 4th. It covered 1/4th of the total area of Pakistan, whereas, superfloods of 2010 covered 1/5th area.
Climate Change is the reason behind this unprecedented floods in Pakistan, but bad governance couldn't be ignored, which mad it worse.
It was not like riverine floods in past, which could be predicted, but unprecedented heavy monsoon rains and glacial melting due to climate change. Usually monsoon enters Pakistan via KPK, Punjab, Sindh and then to Balochistan fulfilling the water needs, but this time it changed its course. This time monsoon changed its route and spell were five to six than normally one or two.
Residents along with Indus river banks were most vulnerable, because the drainage infrastructure failed badly.
Federal and Provincial governments, Pakistan Armed Forces, civil society, political and religious parties did their best to overcome this menace, but the scale of devastation demands more.
Besides Floods, climate change is behind torrential rains, forest fires, heatwaves, storms and droughts all over the world.
There are different views about these unusual rains and floods, either it is man-made or natural.
According to optimistic view, these kind of floods comes seldom, and if came in future, we'll be well prepared.
Pessimism says that in future these kind natural disasters will be regular and havoc.
Concluding/Suggestions:
Starting preparations for precautionary measures is far important than to discuss the causes behind it, i.e. man-made or natural.
All kinds of buildings/infrastructure should be removed from the water flow path, according to the best scientific and calculated way.
Solar energy should be subsidized and new constructions should use at least 50% solar power.
Drainage infrastructure projects should be reconstructed with careful and calculated measurements keeping in mind its aftermaths.
Dams and Reservoirs should be constructed.
Establishment of an institution, fully functional, devolved and having power to administrate over future infrastructure.
Local government is pivotal for the good governance and best for disaster management. Local government should be enabled with timely elections, budgetary allocation, administrative and policy making powers. Natural disasters like floods could be handled with more efficiency and effectively at grass root levels, because NDMA (National Disaster Management Authority) established since 2007 failed due to non devolution.
