I am a beginner with a small orchard in a very dry and warm part of
France. The water supply is about 70 m away in a stream and 7 meters
lower.

I need advice on pumps, diesel I understand would be better as there is
no electricity supply anywhere near the orchard? Can pump head mean
two things, the depth from which the pump can pump, and the distance it
can supply? How much could I expect to pay for a pump? I also would
need to be able to either carry it, or load it into the back of a van...

Any comments or advice gratefully received

Others have covered most things. Just one thing to add is to ensure
from the specification that whatever pump you use for delivery to your
irrigation system is specified to deliver the at the rate (litres/min)
and pressure required by the sprinklers etc that you plan to use (see
the sprinkler specs) and do as Charlie says bear in mind the friction
and turbulence losses that occur in small bore pipes - it will be very
noticable if you're moving water over any appreciable distance.
