  • 1.Transformational Opportunities to Perennialize Global Farming Creating an EverGreen Agriculture Dennis Garrity UN Drylands Ambassador Distinguished Board Research Fellow, World Agroforestry Centre Chair, Partnership to Create an EverGreen Agriculture

2. Sustainable Development Goals Food security Poverty eradication Health Gender equity Universal Education Reversing land degradation Climate change resilience Energy for all 3. Trend in non-climate related net primary productivity 19812006. Conijn et al 2013. New post-2015 Sustainable Development Goal: Zero Net Land Degradation by 2030 4. Five million hectares of croplands now dominated by fertilizer-fodder-fuewood trees in Niger 5. A Parkland Renaissance on Niger farmlands 6. Total Global Emissions are accelerating but land-based emissions are declining Land-use change black line: Includes management-climate interactions Source: Le Qur et al. 2012; Global Carbon Project 2012 7. The albida halo effect Microclimate buffering Soil fertility improvement 8. Microclimatic variation: Crop Canopy Temperature 9. Evergreen agriculture with Faidherbia albida in Zambia. 10. Faidherbia Trial Results in Zambia Maize yield - zero fertiliser 2008 2009 2010 ----- Tons/ha ------- With Faidherbia 4.1 5.1 5.6 Without Faidherbia 1.3 2.6 2.6 ________________________________________________________________________________________________________________________________________________________________________________________________ Number of trials 15 40 40 11.

Impact of fertilizer trees on maize yield under farmer management _______________________________________ Plot management Yield (t/ha) Maize only 1.30 Maize + fertilizer trees 3.05 ____________________________________________________________ 2011 Survey of farms in six districts (Mzimba, Lilongwe, Mulanje, Salima, Thyolo and Machinga) 13. FaidherbiaGliricidia Maize stubble Faidherbi a Gliricidia Maize DRY SEASON WET SEASON Fertilizer-Fodder-Fuelwood Trees in Food Crop Production Systems 14. Types of Evergreen Agriculture 1. Farmer-Managed Natural Regeneration (FMNR) on cropland 2. Conservation agriculture with trees (CAWT) 3. Conventional food crop production interplanted with trees 15. 17 Countries engaged in EverGreen Agriculture in Africa Farmer Managed Natural Regeneration Conservation Agriculture with trees Trees interplanted in conventional tilled cropland Farmer Managed Natural Regeneration + Trees interplanted in conventional tilled cropland 16. EverGreen Agriculture Partnership 17. What do we need to do to fully mobilize for the upcoming global revolution in agroforestry upscaling? Urgent need to map agroforestry across the world at global, regional, and national scales Create a Global Agroforestry Assessment based on national assessments Develop a global plan to upscale agroforestry Staff up in linking agroforestry science to 18. Sri Lanka Leadership on EverGreen Agriculture 1. Participate actively in the Global Partnership to Create an EverGreen Agriculture 2. Activate a Sri Lankan Network for EverGreen Agriculture 3. Lead a global effort to upscale dendrothermal power generation with N-fixing trees 4. Host an international workshop on dendrothermal technology in 2015 19. The Perennialization of Agriculture at the heart of a truly sustainable planet. 20. Total Global Emissions are accelerating but land-based emissions are declining Land-use change black line: Includes management-climate interactions Source: Le Qur et al. 2012; Global Carbon Project 2012 21. The Perennialization of Agriculture at the heart of a truly sustainable planet. 22. The Perennialization of Agriculture at the heart of a truly sustainable planet. 23. For More Information World Agroforestry Centre www.worldagroforestry.org Evergreen Agriculture web site www.evergreenagriculture.net Email contacts: d.garrity@cgiar.org 24. Channels for Reducing Vulnerability 1. Buffer crop production from drought stress -- Sustain higher and more stable yields by more favorable microclimate -- Conserve and enhance soil organic matter, infiltration and water holding capacity 2. Tree crops generally less severely affected by drought, heat, excess water 3. Greater diversity of income sources 25. Farmer-Managed Natural Regeneration on crop fields: Initial Stages 26. A Parkland Renaissance on Niger farmlands 27. The albida halo effect Microclimate buffering Soil fertility improvement 28. Zero Net Land Degradation Classify all land into three categories: Degrading Regenerating Stable Monitor land degradation and regeneration in terms of biomass production. Calculate the ratio: Regenerating/Degrading The target is a ratio exceeding 1.0 29. What is Evergreen Agriculture? A form of more intensive farming that integrates trees into crop and livestock production systems. Evergreen farming systems are double- story systems that feature both perennial and annual species (food crops and trees), maintaining a green cover on the land throughout the year. 30. Wheat production with Paulownia trees > 3 m hectares in China 31. Training for farmer groups curricula material for universities and technical colleges improved Improved government policies Improved technical capacity of extension and government scaling up efforts Improved communications and awareness Provision of products and services by the Private sector Technical and institutional capacity built to support spread of EverGreen Agriculture Collaboration between organisations supporting EverGreen Agriculture EverGreen Agriculture PartnershipEverGreen Agriculture Partnership
