Getting to know
manioc/cassava
Drought resistant crop in
tropical and subtropical
areas (Africa, Southeast
Asia, the Caribbean and
Latin America) that can
grow in marginal soil
conditions.
Produced mostly on
small-scale, nonmechanized farms as a
subsistence farming crop.
Versatile
Food source for people and
livestock Edible roots can be made
into high calorie pastes/flours and
leaves are a good source of protein
and vitamins A & B
Commercial applications Binding
agent (paper/textiles)
Big potential A 40% increase in
cassava production helped Ghana
reduce undernourishment more
rapidly than any other country
between 1980-1996.
Current limitations
High yield losses to pests
and diseases
Reproduction by stem cutting
Harvesting is labor intensive
Current limitations
Processing methods (grating,
pounding, scraping, drying, etc.) are
labor intensive.
Any new processing methods or
devices must be thorough and fast.
• Some cassava varieties contain
cyanides, which must be removed.
• Cassava roots can deteriorate
quickly after harvesting.
A better processing method/device
can have a positive impact on
nutrition (Ghana example) and
economic development (substitute
for imported grains/flours).
