Pakistan is so highly inefficient, that it could attract FDI if it puts in place the right incentives for growth and disincentives to prevent money going into less productive (or export revenue earning) ventures.
Modernizing agriculture with new seed varieties, modern irrigation (which brings nutrients and water to the roots), and more land under irrigation once the dams come on line throughout this decade have the potential to at least double yields, just this decade. (Fully catching up with world standard could yield a 3-5 fold increase in agricultural output)
It comes down to management and political dynamics shaping markets and the weather.
Population is also growing; by the end of the decade the population could easily be 40+ million people (to reach between 260-270 million people) or nearly 20% increase in the population (of the prediction of reaching 363 million people by 2050 holds true). So consumption led growth could see a rise in GDP.
Another factor is the weather patterns over the next decade. Currently we are in a La Niña weather pattern causing less snow pack in the mountains and drought in Afghanistan. Should the pattern change to El Niño, if managed properly, we can channel as much of the expected flooding to refill ground water acquifers in Pakistan and the region, and a bumper crop could yield cheaper raw materials for the textile production or cheaper food for consumers. The last big floods in Pakistan in 2010 were in a year that started as an El Niño year. A global effort to end the famine in Afghanistan (through rebuilding their irrigation and water storage system) could be made easier if we get an El Niño year soon, and if people are retrained to become farmers again. Afghan cotton could feed the textile industry, lowering raw material costs.
