  3. 3. Wheat Production in Sub-Saharan Africa and The Prospects for Expansion …..
  4. 4. Wheat Production in Africa Wheat is grown on around 10 million ha in Africa, where it is a major staple food crop for several countries, and an imported food commodity in all of Africa. Consumption (about 50 million tons) is twice the production level and the gap is widening because of increased population, change in human diet and food preferences, Observed yields are generally Low due to several constraints including drought, diseases and insect pests, in addition climate change effects and increased prices of agricultural inputs that are rarely applied adequately. 4

  6. 6. Wheat Production in AfricaThe food commodity crisis in 2008 jeopardized food security inmany wheat-importing countries, leading to a revived awarenessof the serious threat to Impact of increase of prices of major staples on tradefood security and balance in 2008social stability in many of the world areas,particularly Africa 6
  7. 7. Implications of the Food Crisis:Countries moving from self-reliance to self sufficiency
  8. 8. Wheat Production in Africa- Projected Expansion Wheat in Africa is predominantly grown in temperate climate areas (Northern and Southern Africa) and to a more limited extent in tropical areas, generally at high elevation (Eastern Africa). However, due to the huge wheat deficit and the ever-increasing demand for wheat products the boundaries of wheat production has extended to non-traditional hotter and dryer areas in some parts of Africa, e.g. Nigeria (West Africa), southern Algeria, southern Libya and Sudan. Sudan plans to extend wheat production in the high terrace areas in the north and both Eritrea and Ethiopia plan to expand irrigated wheat in mid-altitude and lowlands . Kenya strategic wheat national research plan identified an area of about 300,000 ha in low rainfall areas as the greatest potential region for wheat production increase. Other countries such as Mauritania, Niger and others are also projecting to introduce wheat in the prevailing production systems. 8

  11. 11. Wheat for Food Security in Africa and the Vision ofThe New Partnership for Africas Development (NEPAD)The investment in sustainable development of Wheat Production to enhancefood security in Africa is very much in line with the New Partnership forAfricas Development (NEPAD) vision for Africa holds that, by 2015,Africa should: Attain food security; Improve agricultural productivity to attain a 6 percent annual growth rate; Develop dynamic regional and sub-regional agricultural markets; Integrate farmers into a market economy; Achieve a more equitable distribution of wealth. 11Source:
  12. 12. The Comprehensive Africa Agriculture Development Program (CAADP) The Comprehensive Africa Agriculture Development Program (CAADP) is a program of the New Partnership for Africas Development (NEPAD) that has been endorsed by African Heads of State and Governments as a vision for the restoration of agricultural growth, food security, and rural development in Africa. A specific goal of CAADP is to attain an average annual growth rate of 6 percent in agriculture. To achieve this goal, CAADP aims to stimulate agriculture-led development that eliminates hunger and reduces poverty and food 12
  13. 13. The Comprehensive Africa Agriculture Development Program (CAADP)CAADP’s work falls under 4 pillars, each dealing with key issues:  Pillar 1: Framework for Sustainable Land and Water Management (FSLWM) seeks to extending the area under sustainable land management and reliable water control systems;  Pillar 2: Framework for Improving Market Access (FIMA) seeks to improve rural infrastructure and trade-related capacities for market access;  Pillar 3: Framework for African Food Security (FAFS) seeks to improve risk management, increase food supply, improve incomes for the poor and reduce hunger and malnutrition; and  Pillar 4: Framework for African Agricultural Productivity (FAAP) seeks to improve agricultural research, technology dissemination and adoption through strengthened agricultural knowledge systems to deliver profitable and sustainable technologies that are widely adopted by farmers resulting in sustained agricultural growth. 13

  20. 20. Challenges Associated with Climate Change Rising temperatures: Higher temperatures will reduce crop productivity Increased frequency of droughts Excess rainfall/flooding Milder winter Increase in the areas affected by salinity Changes in crop cycles Newly emerging pests and diseases 20

  22. 22. Infusing Greater Genetic Diversity ICARDA gene bank holds valuable collection of genetic resources of ICARDA mandated crops Genetic resources of wheat landraces and its wild relatives are adapted to the fragile ecosystems of the dry areas Targeted exploitation of wheat relatives would result in valuable material for enhancing productivity in the era of climate change 22

  25. 25. Contributions of Synthetic wheat Synthetics have exponentially increased genetic diversity in wheat • Yield under drought and irrigated conditions • Multiple disease • Leaf, stem, and yellow rusts • Yellow Leaf Spot (= tan spot) resistance • Nematode resistance • Septoria leaf blotch resistance • Salinity tolerance • Pre-harvest sprouting tolerance • Insect pests tolerance After introducing a novel DD genome (Ae. tauschii), now work starting on using novel AABB genome (T. dicoccoides and T. dicoccum) in new synthetics.

  27. 27. Development of Stress Resilient Crop Varieties Great accomplishments have been made by public and private institutions in identifying genetic variation for the key traits associated with stress tolerance leading to development of stress resilient crop varieties. Several success stories reported on combining multiple disease resistance (e.g. stem Ug99 + Yellow rust + Septoria LB); Heat Tolerance and Drought tolerance. 27

  50. 50. Seed Production & Delivery Seed is the mean for delivering agricultural-based technologies to farmers and therefore plays a critical role in research-for-development continuum ICARDA is one of the CG centers with a functional Seed Unit addressing seed system constraints to ensure impacts of research are fulfilled at farmer and community levels The primary objective of the Seed Unit is to strengthen National Seed Systems, both the formal and informal sectors by:i. Supporting public seed sector to become more effective and competitive,ii. Stimulating private seed sector participation through policy influence,iii. Designing alternative seed delivery systems for dry or marginal areas and resource poor farmers,iv. Assisting in emergency seed relief and rehabilitation following conflicts and/or natural disasters 50
