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, non-mechanized 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
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).
