“Experts classify at most 11 percent of the land,
and perhaps only 7 percent, suitable for crop production
under present techniques of cultivation. This analysis further
suggests that no more than 28 percent of the land should be
cultivated if using optimum techniques for soil and water conservation.”
Using 28% gives 0.174 acres of cropland per person

corn/rice avg 0.347 Cal/sqm/kg/ha
http://data.worldbank.org/indicator/AG.YLD.CREL.KG?locations=HT
~1000 kg/h grain yields
This all works out to 671 Cal/person
So in round numbers Haiti would need to triple it's average grain
production to provide 2000 Cal/person growing corn/rice on it's
cultivatable land.
(World average production is currently 3386 kg/ha, which would be more than
adequate)
