Guiding Policies Climbing beans in Rwanda: sharing the success, challenges and implications in enhancing food and nutritional security for small-holder farmers Dr Daphrose GAHAKWA Deputy Director General/Research RWANDA AGRICULTURE BOARD Rwanda Vision 2020 MDGS EDPRS PSTA CP 13 th February 2012 Beans are rich in: Proteins (22%) Carbohydrates (32%) Fibres (56%) Why beans? Micro-nutients (Fe: 70 ppm); Zn (30 ppm); vitamins A and B They are regarded as a near-complete food Nutritional importance Beans are a High Value Crop contributing: 65% dietary proteins and thus considered: Vegetable meat for the poor and the rich in Rwanda At 60 kg per capita (17 kg average for Africa) bean consumption in Rwanda is the highest in the world.
Why Climbing beans in Rwanda? High population density Increased Productivity per unit area: Climbing beans save land Intensify production Low disease incidence on pods far removed from soil surface Yield 3-5 tons per ha Percentage of households cultivating different crops Source:EICV3, NISR 2012 60.00 50.00 Type of varieties grown by the cropping season A and B, 2010/2011) Bean Research Percent of households 40.00 30.00 20.00 10.00 improved climbers local climbers improved bush local bush The goal of beans research is to contribute to sustainable improved food security, quality nutrition and income earning through improved productivity and commercialization of common beans. 0.00 Season B Season A
Specific Objectives 1. To develop high yielding varieties that are: tolerant to multiple production constraints (diseases, pests, poor soils, drought) nutritionally superior with high market demand 2. To develop good agronomic management innovation (IDPM, IFSM) 3. To forge strategic partnerships to disseminate and promote utilization of research innovations Major successes: Variety released 1962-2012 About 54 released climbing bean varieties documented Major agronomic traits Major economic attributes R R S S High yields of 3.5 5.0 Ton per ha Resistant or tolerant to major pests and diseases Tolerant to heat and drought A. Varieties in diverse market classes for food security and better nutrition B. Navy beans for domestic and export markets C. Snap bean for domestic and export markets (and source of vit. A) D. Sugar and large white beans for domestic, regional and international markets
VARIETY DEVELOPMENT, SELECTION AND RELEASE Climbing beans encourage integrated systems approach Increasing soil fertility benefits of climbing beans and associated agro forestry interventions under smallholder production systems INTEGRATED SOIL FERTILITY MANAGEMENT Conserve environment by massive leafy canopy providing soil cover most of the year Leafy canopy and biomass could play big role in CO2 sequestration? Variety accounts for 40% while good husbandry practices contribute 60% of the yield Nodulation and N-fixation estimated at 40 kg N/ha

Concluding Remarks Acknowledgements Climbing beans have contributed positively to the food security and nutrition in Rwanda and beyond More research and resources are needed to find innovative solutions for the challenges that have been highlighted and others that may develop including climate change GOR AGRA ASARECA CIAT HARVESTPLUS PULSE CRSP Thank you for your kind attention
