Overcoming the challengesOvercoming the challenges
Can agroforestry contribute to overcome some of the challenges of Ethiopian development? YES!
•Sustainable intensification of mixed tree-crop-livestock systems on farms and within farming landscapes can reverse land degradation, and improve crop productivity, livestock feed availability and food security (Garrity et al., 2010).
Overcoming the challenges (Cont’d)Overcoming the challenges (Cont’d)
Ethiopian government initative• The Ethiopian Government has launched innovative
approaches that include a “Climate Resilient Green Economy” (CRG 2012).
• Faidherbia Program (to establish 100 million Faidherbia albida trees on cereal cropland during the next four years).
• Reforestation of 15 million hectares of land (on farm & communal land)
Role of ICRAFRole of ICRAF
• ICRAF to be deeply engaged in supporting the CRGE (underpinning the government’s programs on watershed management and agroforestry).
• ICRAF led Africa Rising early win project Sustainable tree-crop-livestock intensification as a pillar for the Ethiopian CRGE in collaboration with ILRI, EAIR and MU
Major Objectives of the projectMajor Objectives of the project
• To document local knowledge about integrating trees in fields, farms and landscapes
• Best bet tree species and management options identified
• Needs for development of the tree seed and seedling supply sector assessed
• Effective partnerships for promoting tree-crop-livestock integration to underpin the climate resilient green economy initiative established (the purpose of this dialogue)

Preliminary results on local knowledge Preliminary results on local knowledge
What does the current system look like?Eucalyptus is the dominant tree species in the
systemNative tree cover (both in forest and as AF) has
been continuously decliningLoss of soil is apparent in many locations within
the landscapes
What do farmers know and explain well? Major causes for loss of tree cover
Expansion of agriculture (crop & livestock), un- sustainable use of different uses of forest products (e.g., fire wood)

Major challenges: Especially AF species (Bekoji)Major challenges: Especially AF species (Bekoji)
• Free grazing (livestock damage seedlings)• Lack of seedlings of appropriate species• Slow growth rate of native species (which are
good as AF species

Key Discussion pointsKey Discussion points
What should be done to make the tree-crop-livestock intensification strong enough to support the green economy initiatives and other multiple roles?
– Policy (e.g., creating synergy among policies)– Research & development (Priorities) – Extension and advocacy– Capacity building – Partnership and networking– Market and Gender
• There is massive tree planting initative that should be commended and what are the measures taken to ensure its success
• Open access grazing management system (What are the experiences in different regions)
• Maintenance and care after seedling plantation
• Planting the right trees (based on farmers preference and ecological suitability)
Points for reflection Open Grazing management and Points for reflection Open Grazing management and post planting management plan..post planting management plan..
• The need to creating synergy among disciplines and scientist from crop, tree livestock etc (unfortunately this is seldom the case)
• Would it be successful without integrating other measures like family planning, education (women), technology development, nutrtional change, etc?
Sustainable Agricultural Sustainable Agricultural intensificationintensification
•Can we talk about sustainable agricultural Intensification with out considering tree as integral part of the system
•Often time crop scientist considr trees on farmlands undesirable ...what is your say on this
Is Crop livestock intensification Is Crop livestock intensification similar to Agricultural intensificationsimilar to Agricultural intensification
