  • 5. UNU-EHS 5 Conservation Agriculture (CA)  CA => increase in soil organic matter & carbon sequestration, fuel-, labour-, and input saving, less drudgery, stable yields - Kenya (Majanen & Scherr 2011; Bayala et al. 2012)  Lower the costs of tillage & weed control with subsequent increase in net returns e.g. Malawi (Ngwira et al. 2012)  May increase labour input for weeding – women  Benefits depends on level of soil fertility depletion  Need for training on use of herbicides and pesticides Chinwe Ifejika Speranza Chinwe Ifejika Speranza Chinwe Ifejika Speranza

  • 7. UNU-EHS 7 Weather Forecasting and Early Warning Systems  Improving services & communication of seasonal forecasts to farmers - Kenya, Nigeria  Farmer uncertainty about their reliability (e.g. Kenya)  Senegal - Farmers better able to adapt to climate change & variability when they apply climate information to choice of seed and crop (Sultan et al. 2010)  Potential to improve the linkages between the Min. of Agriculture & the Meteorological Agencies e.g. Kenya (Shah et al., 2012)  Need to improve forecast communication
  • 8. UNU-EHS 8 Rice Breeding for Africa  More than 30 stress-tolerant rice varieties released in nine African countries  New rice varieties tolerant of salt, cold, and iron toxicity for Africa by the Africa Rice Breeding Task Force  In addition to the ARICA (Advanced RICes for Africa) brand; the NERICA varieties  Challenge: quantity of seed produced & disseminated to farmers - a major bottleneck (Mohapatra 2014)
  • 9. UNU-EHS 9 Financing Adaptation in Agriculture  Rural finance and micro-credit in various countries, often used by women (e.g. Sudan, Osman-Elasha et al., 2008, Ifejika Speranza 2010).  Challenge: a steady stream of finance needed
  • 10. UNU-EHS 10 Index-Based Weather Insurance  Index-based weather insurance (Malawi; Hellmuth et al., 2009); weather index micro- insurance (Tigray, Ethiopia); Ethiopia’s Productive Safety Net Program (PSNP) (Oxfam America 2009)
  • 11. UNU-EHS 11 Introducing or Improving Irrigation  Need to embed irrigation expansion within systems-level planning (van de Giesen et al., 2010; Burney and Naylor, 2012; Laube et al., 2012).  Rain-water harvesting in ponds; River-water abstraction; Drip irrigation technologies - foster diversification to high- value horticultural crops (Karlberg et al., 2007; Woltering et al., 2011; Biazin et al., 2012).  Improving water use efficiency for both rain-fed and irrigated production (Weiβ et al., 2009)  Side-effects: Risk of malaria & other waterborne (snails) diseases IPCC 2014
  • 12. UNU-EHS 12 Maladaptation Challenges  Biofuels - Promotion of Jatropha  Use of wetlands for cropping (Hamisi et al 2012)  Increased charcoal production (Hartmann and Sugulle, 2009)
  • 13. UNU-EHS 13 Integrating Adaptation & Mitigation  Farmer Managed Natural Regeneration  Integrating perspectives - Governments favour mitigation while local communities prioritise adaptation (Fisher et al., 2010; Somorin et al., 2012).  Jatropha - potentials and limitations (Hanff et al 2011)  2010, the Kenya Agricultural Carbon project (World Bank 2014)  The Ethiopia CDM afforestation project (UNFCCC CDM 2009) IPCC 2014
  • 14. UNU-EHS 14 Fisheries and Aquaculture  Aquaculture - rural southern Malawi - Integrating ponds into smallholder farming systems increases food production & income during times of drought (Dey et al. 2014)  Need for more research on adaptation in fisheries and aquaculture IPCC 2014
  • 15. UNU-EHS 15 Adaptation in Livestock Production Systems  National Livestock Marketing Information System - SMS & information boards - Kenya - Kariuki et al. (2009)  Provision of shade & water to reduce heat stress from increased temperature  Reduction of livestock numbers – a lower number of more productive animals leads to more efficient production & lower GHG emissions  Breeding - Changes in herd composition (Central Uganda National Animal Genetic Resource Centre and Databank, Hoffmann 2008)  Improved management of water resources (IFAD 2009; World Initiative for Sustainable Pastoralism 2010)

  • 18. UNU-EHS 18 Conclusions and Outlook  Improving efficiency - access to inputs & markets for outputs  Improving policy and institutional arrangements  Monitoring and assessing adaptation  Funding and technology transfer and support  Strengthening institutional capacities and governance  Strengthening capacities of scientific institutions in Africa  Extending small case studies to larger areas  Science – Policy / Practice Linkages
