pakistan can help the food security issues.  
pakistan is one of the rich most land on earth.poeple here have all the resources to grow food but they are limited by few factors,
1)..poor financial capabilities
2)..lack of education and probably more of orientation
3)..lack of institutional support
4)..traditions and customs
5)..poor electoral and ruling system
if these problems are addressed,pakistan will not only be able to overcome its own needs of food but also will be able to export food and food products thus helping the world to overcome the issues of food securities.
i put an example in front to make my point more clear.
muzaffargarh canal,,which runs through the centre region of muzaffargarh district is no doubt the hub of our agricultural system but it poses following problems also
1)the canal basin and margins are made of mud and not bricks or stones,,,resultantly a huge quantity seeps through and creats large pounds of stagnant water ,,regions called ,,same,,in local language..this huge amount of water is precious and would benifit the region if used for irrigation in tales of branches of the canal
2)..these areas are equally fertile if this issue is sttled and production of food will be doubled by eliminating this issue
3)..50 %of the cultivated land yeils much less than its capacity,,because of higher water table in the near by areas again due to seepage of water through canal
4)the land which is free from the above cited issue yeilds lesser due to non availabilty of water in the irrigation system timely..
thus by taking a single step of making the canal basin cemented floor.
