Module 1Overview: Rice in AfricaUnit 3 –AddressingthechallengeoflowproductivityinAfricanlow Africanrice ecologies: NERICA ® varietiesNearly half of sub-Saharan Africa’s 700 million people live below thepoverty line (World Development Indicators, 2004). With populationgrowth rate exceeding the growth rate in regional food production,and with only limited foreign resources to sustain increased levelsof imports, the future for Africa’s poor appears grim.WARDA’s breakthrough in producing the ‘New Rice for Africa’(NERICA), based on crossings between African rice (Oryzaglaberrima Steud.) and Asian rice (O. sativa L.), offers welcomerelief to Africa’s rice farmers. It is a new and unique opportunityfor sustainable agricultural development in the rainfed environmentswhere most of Africa’s rice farmers earn a living.NERICA varieties have high yield potential and short growth cycle.Several of them possess early vigor during the vegetative growthphase and this is a potentially useful trait for weed competitiveness.Likewise, a number of them are resistant to African pests anddiseases, such as the devastating blast, to rice stemborers andtermites. They also have higher protein content and amino acidbalance than most of the imported rice varieties. Participatoryvarietal selection (PVS) trials in rainfed environments across WCAhave met with an enthusiastic response from farmers.9
