-Give us a sense of the scale of your farm here, be the center ** that we see there. You said that's 440 meters long I think, so nearly half kilometer long. So each of these circles is about a kilometer wide.-So this is equivalent to 120 football pitch.

-And how many these crop circles almost you got?

-We have 102 here. -I get this.

-I have 10,000 football to care about.

In this field, Ali is growing al*, a crop used to feed animals. Most is exported to Sudan, its Islamic neighbour in the Gulf states, where their remaining water supply is disappearing fast. Ali also uses the crop for the farm's own herd of milking cows, who shelter from the searing s* sun in giant purpose-built shades.

-You've got what look like dozens of Britain cows?

-Year.

-We could be in Lincolnshire or D* in the UK! There are two and half thousand dairy cows here, cared for by Dr. Muhammad.

-Dr. Muhammad!

-Oh, hello!
