Growing Rice Consumption in SSA Causes: • Population growth and urbanization • Consumer preference and diet changes • Increased consumption of food away from home • Increased participation of women in labor force • Convenience and ease of storage and cooking Sources: IMF and FAO-STAT
The growing GAP between SSA rice Consumption & Production • Production not keeping pace with consumption • Widening domestic deficit met by importation • Accounts for more than 30% of world rice imports • Import bill of more than US$ 5 billion in 2008 West and Central Africa rice trends Source: FAO-STAT
Projection of milled rice consumption in Africa 17 M t Source: FAO, ECOWAS and AfricaRice projections for 2008 – 2020 using the 1987-2006 growth rate (4.28%)
Projection of milled rice production in Africa 7.5 MT Source : FAO and AfricaRice projections for 2008 – 2020 using the 1987-2006 growth rate (3.2%)
Significant changes in rice policy perceptible since the 2008 food crisis • Proactive measures to boost local production in many member States: • Example: Pubic investments in Malian rice sector reached 85 million USD in 2008 and 106 million USD in 2009 • Emergency measures paid dividends • Paddy production in Africa increased by 18% in 2008 • CILSS member states recorded a record production in 2008-2009 with a 44% increase compared to 2007
Potential for Production Expansion Source: Various
African rice is competitive against imports • Estimated Domestic Resource cost (DRC) < 1 indicates that in many countries it is cheaper to produce rice locally than to import. • Estimated Nominal Protection Coefficient (NPC) indicates local production is weakly protected except in Nigeria • Domestic production systems possess comparative advantage and their development could: • Save foreign exchange • Contribute to economic growth WARDA, NARS, 2007, 2008
Rice yield by ecology comparable to other major rice producing regions • Land productivity not significantly different from than other regions • Rice yield in rainfall ecologies (upland and lowland) comparable to Asia as well • In Senegal yield increased from 2.5MT/ha to 5.8 MT Source: WARDA surveys 2005, Hossain (2002)
Competitivity of local rice enhanced by upward trend in international prices • Upward trend in prices • Global rice prices are projected to increase by 2.5 to 3% every year until 2017 (USDA, 2008) • High volatility • The variability (CV) of Thai100 up from 15% in 1990s to more than 50% in 2000-08 • Impressive surge in prices in 2008 followed by a fall just as spectacular Source: OSIRIZ/InfoArroz,CIRAD
Rice Production in Africa: Summary of constraints • Low aggregate yield -owing to large share of upland rice farming system and to subsistence farming • Inadequate use of critical inputs • Insufficient development of irrigation facilities • Lack of double-cropping • Limited size of the cultivated area • Widespread use of hand-held tools
Rice Production in Africa: Marketingand policy/institutional constraints • Post-harvest technologies and practices • Poor quality of the marketed product • Insufficient public investment in rural infrastructures • Absence of the private sector in seed production • Limited access to credit • Policy environment not conducive for private sector investment –But this is changing
Project goal and purpose • Goal: To reduce poverty and food insecurity in SSA through sustainable development of the rice economies • Purpose: To generate options for policy and institutional changes for an efficient and pro-poor rice production and marketing system
Project 4 outputs • Output 1: Tools, methods and enhanced capacity for impact assessment, policy analysis and priority setting • Output 2: Rice policy options and institutions for competitive domestic rice production • Output 3: Improved post-harvest systems for competitive domestic rice production • Ex-post Impact Assessment
Implementation • Implemented through and by NARS with Funding and backstopping by AfricaRice: • Impact studies: 16 NARS currently involved • Post-harvest: 3 NARS currently involved • Rice Statistics 21 NARS currently involved • Use of common methodologies • Sharing of questionnaires and survey designs • Sharing of analysis tools • Training • Methodology-learning workshops • One-one training on the job
Methodologies • Econometric modeling • Experimental economics • Psychological methods • Policy Analysis Matrix (PAM) • Multi-market models • CGE models • Household surveys • Aggregate time series data (e.g. FAOSTAT)
…Ex-Post Impact Assessment Methodology • Counterfactual outcomes framework: • Comparing outcomes with and without intervention/treatment • Average Treatment Effect (ATE) methodology • Estimation of actual and potential impacts • Aggregation to national and regional level impacts using population census weights
Enhanced NARES capacity in policy analysis and impact assessment • 155 NARS Economists and University Students trained in ex-post impact assessment since 2002 • 20 NARS trained in the Policy Analysis Matrix (PAM) tool since 2005 • 19 NARS visiting scientists hosted since 2006 (13 in 2009 alone) • Development of Stata modules for ATE adoption and ex-post impact assessment being used by NARS collaborators , SSA-CP post docs and Ph.D & Msc students at Ibadan, Pretoria , London & Gottingen universities • Development of the Emergency Rice Initiative Spreadsheet (ERIS) during the 2008 food crisis to assist member states boost local rice production
Software tools for impact assessment: the Stata impact module
Linkage of international prices to Africa prices • Price changes in Thailand are transmitted faster to Senegal than to Mali • Contemporaneous price changes (short-run effect) between Thailand and Senegal or Mali is not statistically significant • 19% of the price difference between Senegal and Thailand is eliminated each month • Nearly a year is required for full adjustment to price change in Thailand Bamba et. al. (2008)
Further evidences of SSA comparative advantage in rice • Rice maize stratification project results provide ample evidence that rice production systems in Benin, Guinea, Nigeria and Senegal are competitive with Asian imports • Ncho et al. (2008) • Irrigated rice production in Togo enjoys substantial comparative advantage vis-a-vis imports Koffi-Tessio et. al. (2008) • import demand for rice in West Africa is relatively unresponsive to changes in price Sellar (2009)
Irrigated rice farmers’ technical efficiency in the Senegal River Valley • Improved technologies like enhanced short/medium duration Sahel cultivars and the use of the ASI thresher have a positive impact on technical efficiency as well the compliance with input recommendations • The modest technical efficiency scores observed implies that more research and extension efforts are warranted to increase technical efficiency Diagne et al. (2008)
Experimental end-market analysis to strengthen value chains of Senegal River Valley rice (Demont et al., 2009) Elicit WTP to upgrade local low-quality rice (red dish) into 3 alternatives: • Imported Thai-25 rice • Unlabeled local quality rice • Labelled local quality rice (Rival, PINORD) 2009 Research Days, 2-5 November, Cotonou
Consumers pay premium of 43 F/kg for local quality rice relative to imported rice • They further add 29 F/kg for Rival label • WTP to upgrade local low-quality rice into alternative rice drops after sensory test due to good taste of local mixed-grain rice 2009 Research Days, 2-5 November, Cotonou
Factors Affecting NERICA Adoption • Access to extension/training have significant effects on NERICA adoption • A large number of farmers adopt the NERICA because of its non-yield varietal attributes: • short growth cycle • plant height • consumption and grain qualities • Possible gender bias in the dissemination of NERICA varieties in Guinea.
Main conclusions on NERICA and ASI adoption and impact • A low diffusion rate and lack of seed have so far limited the adoption of the NERICA • NERICA adoption impact on rice yields is heterogeneous with some farmers not experiencing any yield increase when adopting NERICA • Positive impact on income, child schooling, health, food consumption and poverty • Nerica impact significantly higher for women than for men (Benin, Cote d’Ivoire, Gambia and Guinea) • The ASI thresher reduces labour needed for threshing so it can contribute to attain the objective of double cropping in the SRV.
Future research direction: Policy Research and Advocacy • A platform for Rice Policy Research in Africa built on the Rice data systems project collaborative framework • Partial equilibrium model of SSA rice sectors to: • Assess the medium- and long-term effects of changes in global rice markets and their policy implications for sub-Saharan Africa food security • Simulate the effects of alternative policy and investment options for Africa’s rice production in the medium to long terms
Future research direction: Policy Research and Advocacy • Research to develop rice value chains in Africa: • Analysis of the market failures in the African rice seed sectors • Strategies and policy and institutional options to stimulate the emergence of a competitive processing sector for better quality rice • Strategies and policy and institutional options to stimulate the development of demand-driven rice value chains in SSA.
Future research direction: Ex-post Impact Assessment • Widening of the impact assessment indicators, methods and tools used: • Assessment of impact on more poverty and environmental indicators • Use of randomized control trials (RCT) • Estimation of direct and indirect impacts • Use of ICT tools for data collection and information dissemination (PDA and web-based tools).
