Organic Agriculture for Restoring Degraded Landscapes and Livelihoods:
The Tigray Experience
ETHIOPIAMountainous
1.12 mill sq km>14 mill small-holder farmers
>Cultivated area average 0.94 ha
per family
Ethiopia is the ‘water tower’ of eastern Africa providing over 80% of the waters of the Nile plus water to N Kenya, Somalia and Djibouti.

Land degradation, particularly soil erosion is Ethiopia’s most serious problem
Any and all agricultural improvements need to be based on ecological intensification
Ethiopia’s agrobiodiversity wealth• Over 5,000 years of farmers’ knowledge and skills • Agro-biodiversity wealth
–Vavilov Centre with over 190 crop species still cultivated–Great varietal diversity within crops –Very low use of external inputs, e.g. chemical fertilizer –Farmers’ dislike / distrust of debt
• Governance in the hands of local communities, including farmers’ rights to save, use and sell their own seed
A glimpse of Ethiopia’s agrobiodiversity
wealth
Enset (false banana) above and teff belowA few of the huge range of
sorghum varieties
Local Agroiodiversity for Food & Nutrition Security and Income Generation
Enset: 250 sq m supplies all carbohydrate needed for a family of 5 for a year
• Harvested product can be stored for 15 years• Highly drought resistantTeff: highest value cereal on market (85 USD/t),
compared to maize, (25 USD/t)• High nutritional value, • Harvested grain can be stored for 10 years
without loosing viabilitySorghum: very drought resistant• Many different food and beverages uses
Origin of the Tigray Project
In mid-1990s, ISD asked by the Ethiopian Government for an alternative to the Sasakawa Global approach promoting increased use of chemical fertilizer, but suitable for only about 10% of the country--classified as high production potential areas
• ISD established in 1996 to implement the Project “Sustainable Development and Ecological Land Management with Farming Communities in Tigray” = The Tigray Project
#IFOAMRio@IFOAMorganic
Livelihood and landscape componentsBylaws - communities restore local controlBiological and physical water & soil conservation, through using
multipurpose local trees, i.e. Sesbania and local grassesManaging grazing, stopping access to vulnerable land (watersheds),
so grass, herbs and trees can growRestoring soil fertility through compost, and helping farmers avoid
debt paid for chemical fertilizer

Landscape rehabilitation started in 1996, pictured in 2003 (similar examples now seen in many place) throughout

The 4 Principles of Organic Agriculture Applied
• Ecology – restores and maintains ecosystem services (good soil, water availability, pollinators)
• Health – healthy soil produces disease and pest resilient crops
• Fairness – Involves all social groups in the local communities, women, men, disadvantaged groups such as elderly couples, landless youth, families challenged by HIV/AIDS, etc.
• Care – the communities take responsibility for caring for their environment through bylaws
#IFOAMRio@IFOAMorganic
Wheat infested with stripe rust and sprayed – gave yield of 1.6 t/ha
Wheat grown on composted soil resisting the rust – gave yield over
6.5 t/ha

Landscape Benefits of Compost
Carbon brought back to the soil as humusNitrogen in the protein of organic wastes,
including urine, returned to the soil Other nutrients in compost recycled for healthy
growth of crops, animals and peopleWater retention for improved local hydrology,
with raised water tables, longer water flows in streams enabling 2 crops per year
Increased resilience to extreme weather events
Livelihood benefits of compost
Yields of cereals and pulses doubled Soil and crops with increased resistance to wind
and water erosionWater availability improved
Springs reappear, persist and streams run for longer through the year
Water tables raised (farmers dig shallow hand dug wells) Crops survive dry gaps and stay green for 2 weeks longer
than others at the end of rains

Additional Livelihood Benefits of Compost
Farmers avoid debt from getting chemical fertilizer on credit – now costing USD 130 per 100 kg – Farmers making bioslurry compost can sell one
sack (approx. 100 kg for ETB 100 or USD 5.8– Competent farmers make 35 to 100 sacks a yearFarmers, particularly women, diversify their production baseWomen say the food tastes better and their families’ hunger is satisfied more easily
#IFOAMRio@IFOAMorganic
Economic benefits of compost
• Inputs (all of which are locally available): – weeds from crop fields– Left over crop residues used as animal feed and
bedding – Animal manure (plentiful)– Vegetable crop residues– Household organic wastes– Labour– Water– Microbial rich soil as an innoculator
Cost benefit analysis for the farmer using chemical fertilizer
• Cost for chemical fertilizer in 2012 was USD 130 per 100 kg
• Average yield of durum wheat grown with chemical fertilizer 1700 kg/ha,
• Sold at USD 50 per 100 kg , farmers income would be USD 850
• Net profit after repaying credit, USD 720
Cost benefit analysis for the farmer from using compost
• Average rate of compost application, 6.5 t/ha• Opportunity cost for making compost
estimated at USD 60 for 6.5 t/ha• Average yield of durum wheat grown with
compost 2500 kg/ha, • Sold at USD 50 per 100 kg , farmers income
would be USD 1,250• As there is no financial outlay, ALL of this
profit stays with the farmer

Planting with Spaceto maximize use of seed and compost
An adaptation of SRI, by growing in rows either from transplanting seedlings or direct sowing, gives
Increased yields with easier and timely management of weeds, pests and easier harvestinge.g. Finger millet and tef, seed rate reduced by 90% compared to
broadcasting, hence more efficient use of seed resources, andGrain and straw yields doubled, i.e. for finger millet from 1.4 t/ha to
3 t/ha grain, and for tef from 1.2 t/ha to 2.5 t/ha or more of grainBecause, root growth greatly increased giving many more
productive tillers (greater root mass = greater shoot mass)

• Improve and expand extension services (ICT)
• Introduce capacity building (ICT)
• Agriculture is very localized
The Ecological way ahead is: knowledge & people intensive
