Description Opuntia ficus-indica (L.) Mill. has been propagated for its fruits and young
pads for human consumption, as well as for forage for domestic livestock for
hundreds of years. Recently, it has been suggested that this plant could be beneficial
in arid regions of the world where it has not been introduced. We used
environmental tolerances for O. Ficus-indica gleaned from literature reviews, a
rapid survey of this cactus growing in Jordan, and climatic data in a Geographic
Information Systems (GIS) context to build a simple model of O. Ficus-indica
suitability for Jordan. Rainfall and temperature were deemed the most important
environmental variables to be employed in our model. We identified areas of the
country within the range of annual rainfall between 250 and 505 mm and those with
an absolute minimum temperature in any month above 1.5°C. Climate data in our
analysis came from the WorldClim GIS data set. We then eliminated areas with saltaffected
soils. We extracted soil type, temperature and annual precipitation from the
climatic GIS layers at twenty-one sites in Jordan where O. ficus-indica was found to
be growing. Nineteen locations had aceptable values within the environmental
tolerances for annual rainfall and temperature specified by the literature review.
Two locations were drier than the recommended climatic range for the
establishment of catus, and probably represent sites ameliorated by supplemental
irrigation or water harvesting. A conservative figure of seven percent of Jordan’s
89,342 km² was determined to have potential for cactus, based on aforementioned
tolerances of temperature and annual rainfall. Inclusion of high-resolution soil
information and digital elevation layer in the model, when they become available,
would further refine the prediction of areas with potential for O. ficus-indica growth
and cultivation.
