Abstract/Description
Nigerian farmers grow over 60 cassava varieties linked to the International Institute of Tropical Agriculture (IITA) (http://www.iita.org/) research efforts. While yields and the area under cassava have increased over the past decade in Nigeria, there is a lack of rigorous impact evidence—this despite cassava being a major source of food and income. The extent to which an agricultural technology is adopted is a critical input to examine productivity and welfare impacts resulting from adoption.
The Cassava Monitoring Survey, implemented by IITA and the National Root Crops Research Institute (NRCRI)-Nigeria, addresses three policy-relevant research questions: True adoption rate of improved cassava varieties in Nigeria; the effects of adoption on productivity and poverty; and the extent to which self-reported adoption status (versus DNA fingerprinting) over- or under-estimates these effects.
