Environmental Constraints
Dry and/ or cold areas with low production potential
Low soil suitability
Low and erratic rainfall
Steep slopes and mountains
Severe and very severe land degradation
Low to medium climatic production potential
High climatic production potential
Ethiopia - production constraintsand opportunity
Area 1.12 million sq km ; population over 80 million; 84% rural = 16 mill rural families

Farmer practice Row planted
Farmers’ conventional practice (broadcasting seed at the rate of 25 kg/ha or more) vs. Row planting (drilling seed in a line at the rate of 2.5 kg/ha).
