in 60 years, it has increased about 6 times to 170 million.
as a result, we are facing severe food shortages (grain and livestock)
water resources are same.but we can manage existing water in a better way to conquer the hunger.
Food security is not less important than protecting borders.
Acording to a very detailed study of world's population by UNO, Pakistan's population will touch a peak of 440 million till it becomes steady.
it means we need to prepare for smarter living. (of course population control awareness is a solution, but we need to produce more food. If we want to avoid famine conditions in a few years from now, we need to start planning.
we need to use pipes/conduits instead of open canals. it will conserve water against wastage and evaporation.
we need to have smarter distributiories, that don't waste water and land in form of "Sem and thor"
we need to adopt spray irrigation, which doesn't need re-inventing the wheel and there are dozens of off shelf solutions available in market. and we have enough manpower to do it ourselves too.
if we don't want corporate farming, we can go for co-operative local farming. govt can help manage the adventure.
for those who are not familiar with pacmans visible from space, every circlular field of one mile diameter means about half million dollar worth of grain in single harvest. do rest of math yourself.
Sorry for attaching many images, but they are worth thousand words each.
here is the possible implementation.
In map below, i have highlighted areas where it can be done.
Saudi Arabia has been doing it successfully in absolute dry deserts.
we have mixed arid and seasonal flooded areas for this. all we need is building small reserviors to collect and use water at right time.
we have to do this sooner or later. awareness is the first step towards it.
