I hope you go visit there in China or have some Chinese friends who read you some materials about this in details.china is the largest user of drip irrigation system in the world! i just hope they setup drip pipe manufacturing units here and bring cost down to 30000 rs per acre! right now it cost 80-120k per acre and thas stupid price! if one imports from turkey it costs 50k per acre...Pakistani companies are rip offs!
I am also reluctant to support these projects but the worries is on Pakistanis. The way we do things may not be transferrable to other country. Few country can plan things over decades like China.
Besides, if you have nothing, what to be ripped off? sand?
