Beans and Eco-efficiency in a Changing Environment Beans and Eco-efficiency in a Changing Environment Presentation Transcript

  • Beans and Eco-efficiency in a Changing Environment Any real change? Or old wine in new bottles?
  • What changing environment? BIOPHYSICAL SOCIAL • Climate change • More acute poverty? • Soil degradation • HIV / AIDS • Demand for green • Urbanization solutions – Advanced in LAC – Advancing in Africa • Rising costs … – Fertilizer
  • Our mission: INCOME GENERATION FOOD SECURITY
  • Now… Eco- efficiency INCOME GENERATION FOOD SECURITY
  • Or… INCOME GENERATION FOOD SECURITY ECO-EFFICIENCY
  • Bean Researchers • Breeding/Genetic • Seed systems resources – L. Sperling – S. Beebe – J.C. Rubyogo – P. Kimani • Human Nutrition – R. Chirwa – H. Pachon – D.G. Debouck – M. Nyagaya • Pathology • M&E – R. Buruchara – R. Muthoni – G. Mosquera • Economics • Biotechnology – E. Katungi – M. Blair – M. Ishitani • Markets – E. Birachi – J. Tohme – D. Wetaka • Physiology – I.M. Rao
  • Gene pools of Common Bean P. vulgaris P. W C W C Tertiary pool Mesoamerican Andean P. acutifolius Primary pool W C P. coccineus - P. dumosus W C P. costaricensis P. parvifolius W W Secondary pool P. lunatus W C W C = Wild and cultivated forms
  • Common Bean…often associated with higher human population
  • Outputs in the MTP • Output 1: Beans with improved micronutrient concentration that have a positive impact on human health • Output 2: Beans and technologies that improve productivity under low input agriculture of poor farmers • Output 3: Innovative approaches for Reaching End Users with eco-efficient technologies
  • Output 1: Nutrition • Biofortification – economically viable – Conventional breeding – Gene discovery • Goals for Beans – 90-100% more iron – 40% more zinc • Targets – Rwanda and DRC under HarvestPlus – Other PABRA countries – Central America, Caribbean, Brazil
  • Lines with 40-80% more iron Andean FEB 226-parent Meso-American (interspecific)
  • PABRA: Support to PLWHA • Nutrition! • Beans that are less labor intensive, and high yielding • Semi-climbers! (race Durango) – Rustic – Weed competition – High yield – Not commercial but food security item
  • Latin America – a laboratory for linking agriculture and nutrition? • All the problems in the • Institutional support world – Latin American – Poverty + undernutrition Nutritionist Society – Urbanization + – Ministers of Agriculture overnutrition • Post-harvest • Beans are traditional processing and industry involvement • Beans are healthy – EMBRAPA – Cardiovascular disease – CLAYUCA – Diabetes – Cancer
  • The challenge of Latin America: Maintaining bean consumption • To not lose a healthy habit • How ? More attention to consumer traits…? – Flavor? – Flatulence? – Canning? – Cooking time?
  • Energy use for Food - USA Home preparation (19%) Home refrigeration (12.7%) Agricultural Food retail (4.0%) production (20.8%) Restaurants (6.9%) Packaging (6.9%) Processing Transport (13.9%) (15.8%) Source: University of Michigan, Center for Sustainable Systems (http://www.umich.edu/~css)
  • Shorter Cooking time • Energy for Cooking: – Probably even greater proportion of energy in developing countries • A common request from rural producers / housewives
  • • Output 2: Beans and technologies that improve productivity under low input agriculture of poor farmers
  • Andy Jarvis’ ever-popular Stipple map (Drier) (Wetter) mm day-1
  • Climate change, pests and diseases Less rain, more insect pests White flies Stem maggot More rain, more root rots and foliar diseases …and changing distributions!
  • Rain-tolerant interspecific lines (1200 mm in 90 days) FEB 226-parent P. dumosus
  • Climate change and Drought (Drier) (Wetter) mm day-1
  • Good Grain Filling IMPROVED DROUGHT RESISTANCE (GCP / TL-1 / TL-2 / BMZ / RedSICTA) + = Deep roots

  • Dealing with poor soils: The Germplasm in Bernard’s ISFM Equation • A dynamic component!
  • Aluminum resistance: Improving common bean with P. coccineus* 25 SER 16 x (SER 16 x G35346) cm P. coccineus * Ph.D. thesis, Louis SER 16 Butare, ISAR, Rwanda
  • To exploit P. coccineus and P. dumosus that have excessive biomass... • Cross with parents of high harvest index like SER 16 Yield under • Biomass + translocation efficiency Intermittent drought Kg / ha Maturity Yield / d = Improved Yield Interspp. lines ALB 205 3199 68 47 ALB 167 3174 69 46 ALB 213 3029 67 45 Drought res. checks SER 16 2520 63 40 BAT 477 2165 68 32
  • Fertilizer Use Efficiency CIAT pioneered root studies for P uptake with Jonathan Lynch… …and large differences exist in the field SXB 412 …we need to exploit research findings systematically Tio Canela
  • An experienced team in root biology
  • Nitrogen fixation in Heat Tolerant climbing beans for Africa CLIMBERS • An early PABRA success • Continuing demand
  • Options for Nitrogen Fixation • Climbers – Sometimes limited by stakes, labor • Semi-climbers? (Type 3) – Source of high SNF (Puebla 152) – Rustic
  • Output 3: Innovative approaches for Reaching End Users • PABRA - Wider Impact – Estimated 8 M families in 4 years – Marshalling partnerships in new organizational models (e.g., public-private) – Research at the output-outcome interface • Novel seed marketing • Reaching the HARD to reach • Central America and Colombia – Surprising interest – Especially in biofortified crops
  • • Linking bean farmers to market niches – Ethiopia and Peru leading the pack, followed by Uganda, Nicaragua, Bolivia
  • The other side of the coin: Energy use and production close to consumption • 4 largest exporting countries move > 1.6 M tons annually, for >US$ 250M in transport – Does it make sense to ship beans from China to Africa? • Can we increase production closer to consumption? – Mexico City – Kinshasa – Nairobi • We won’t convince anyone not to export… • but we need to understand relative competitiveness of exporting / importing countries, and what we can contribute
  • Conclusion So is anything new?… • Efficient exploitation of interspecific crosses • Working energy considerations into research prioritization • Renewed focus on efficient plant nutrition (N and P) • More consumer traits • New approaches for reaching end users
  • Conclusion • But you don’t necessarily need to do something different to change… • As important as WHAT you do, is… – Where you target – In what social context – For whom
