Management of plant pests and diseases in eastern and central africa

  1. 1. Management of Major Plant Pests and Diseases in ECA: Past, Present and Future Initiatives and Plans at ASARECA. 14-17th April, 2014, Safari Park Hotel, Nairobi-Kenya By Brian E. Isabirye*, Ivan Rwomushana and Fina Opio Presented at the FAO Workshop on Regional Platform for Plant Pests and Diseases *P O Box 765, Entebbe, Plot 5 Mpigi Road, Entebbe, Uganda Tel: +256 414 321885 Mobile: +256 772 352739 Email:
  2. 2. Global Food Security… More than 800 million people do not have adequate food; 1.3 billion live on less than $1 a day. The supply of food in the developing countries will have to rise by around 7 per cent by 2020 to feed the 6.5 billion people in the world. Food demand will double by 2050, requiring a 40% increase in cereal production or and an additional 100-200 million hectares of land. Abiotic stresses (Pests and Diseases) are ever increasing: At least 10% of global food production is lost to plant diseases!
  3. 3. Global Food Security…
  4. 4. Pests + Diseases: Now Enter Climate Change!!! Dry lands Kinyasungwi river, Tanzania Mt. Kilimanjaro, disappearin Protests on high food prices
  5. 5. COUNTRY SITUATION Burundi 28% are food insecure, while 53 % of children under 5 stunted and 8 % have acute malnutrition D.R. Congo 3.7 million severely food insecure and 17.2 million moderately food insecure people. Acute malnutrition affects 11 % of children under 5. Eritrea 37 % of population are food insecure, and import 50 % of cereal. Ethiopia 8.2 million people are chronically food insecure. 40% of the provinces food insecure. 38 % of the children under 5 are underweight. Kenya 3.8 million people need emergency food aid. 2.5 million in urban areas are chronically food insecure. Food in ECA Region: A snap Short Madagascar 33 % are undernourished, while 50 percent of children are malnourished. COUNTRY SITUATION Rwanda 1.7 million people in needed food assistance of whom 294,000 were severely food insecure Sudan In South Sudan over 60 percent of the returnees were (2011) food insecure and in some areas 20 percent of the residents were food insecure. In Darfur 1.7 million people were food insecure. Tanzania Food insecurity is present everywhere in rural areas. 30 percent are food insecure or are vulnerable. 34 percent of children under 5 are underweight or stunted and 6 percent are severely malnourished. Uganda Food insecurity is everywhere affecting 50 percent of the country in most years. In 2006, nearly 7 million were highly and 4 million rural people were moderately vulnerable.
  6. 6. What cuts across ECA Countries? Countries in the region are facing similar challenges to improve agriculture’s performance. Food production in the region is consistently lower than population growth while poverty is increasing Agro-ecological zones cut across political boundaries, and therefore, similar technologies needed. Great untapped opportunities to promote agricultural led growth through sharing of Agricultural research in regional collective action, collaboration and specialization
  7. 7. ASARECA …… Vision Regional leader in AR4D for improved livelihoods in Eastern and Central Africa Mission Enhance regional collective action in AR4D, training and education to promote economic growth, fight poverty, eradicate hunger and enhance sustainable resource use. Goal Enhanced sustainable productivity, value added and competitiveness of the sub- regional agricultural system
  8. 8. Facilitate the generation of TIMPs for the sub-region. Dissemination and up-scaling of appropriate TIMPs across borders. Ensuring an enabling policy environment for agricultural transformation. Enhancing institutional and stakeholder capacities for innovation generation A regional hub and think tank for knowledge, information and learning. What we do
  9. 9. Overview of our Past (OPI) and Future (OPII) Currently, ASARECA has a 10 years Strategic Plan- 2009-2018 OPI and OPII are implementation plans for the last and the next 5-year segments of delivery of the strategic plan OPII will address issues and opportunities that allow delivery in a new, more effective way OPII incorporates change and IAR4D-based research programmes Natural Resource Management and Eco- systems Services Market, Market Linkages and Trade Sustainable Agriculture and FN: Pests and Diseases!
  10. 10. Plant Pests and Diseases at ASARECA Past Initiatives
  11. 11. Bananas Sustainable Management of Banana Xanthomonas Wilt within Banana Cropping Systems in Eastern and Central Africa 2009-2011. US$ 398,458.18 Enhanced Management of Banana Xanthomanas Wilt for Sustainable Banana Productivity in East and Central Africa: 2009-2011. US$ 483,675.00
  12. 12. Bananas… Out Scaling Banana Xanthomonas Wilt (BXW) Control in East and Central Africa, 2012-2013. US$ 500,000. Results: •Recommended BXW control technologies in affected communities in ECA scaled out •Adoption of policy options that support effective implementation of BXW control enhanced •Institutional and technical capacities to sustainably manage BXW and increase access of banana to markets built •Availability of information and knowledge for management of BXW enhanced
  13. 13. Cassava Mega Project on Improved Cassava Productivity and Utilisation in Eastern And Central Africa.. Address the constraints (CMD and CBSD) along the value chain in an integrated multi-disciplinary and inter-disciplinary manner in ECA. Period: 2008- 2011: US$ 4,955,000.00 Integrated Management of Cassava Brown Streak Disease and Cassava Mosaic Disease for Enhanced Productivity and Utilisation of Cassava in ECA: 2008-2013. US$ 642,303.00 The Eastern Africa Agricultural Productivity Program (EAAPP) is strengthening and scaling up regional cooperation in generation of cassava technology, training, and dissemination under cassava RCoE
  14. 14. SorghumIntegrated Striga Management for Improved Sorghum Productivity in ECA. To increase sorghum productivity by reducing crop losses caused by Striga and create market opportunities. 2009- 2011. US$ 370,231.70. Integrated Striga Management for Improved Sorghum Productivity in ECA. 2009-2011. US$ 143,868.84 Sorghum-LegumeIntercrop

  19. 19. Upscaling the various pest and disease TIMPs developed in OPI or available in the region. Build upon past successes and lessons. Facilitate the arrest and containment of the spread of endemic and emerging pests and diseases in ECA Support NARS to sustainably manage transboundary pests and diseases in ECA. Carry out research to generate new information and TIMPs for sustainable management of pests and diseases (MLN, Fruit fly, Fusarium) Establishment ECA coordination mechanisms for coordination of agreed research and development agenda and to monitor pest and disease movements Improve knowledge and information flow and utilization in the region on pests and diseases management. Need to align and refocus our roles in the region:
