the error is on my side, sorry - I simply forgot to multiply with 40. The
recipe is still Fathy's. A single irrigated crop would thus require some 80
hectare acrage finger millet. For the Nile delta, for example, this would
averages 25-30 hectare acrage.
However, during the construction phase one had an still has to calculate
with mold decay.
