• Agricultural production system: beyond food production to the
bigger system within which they are produced and the relations
between and among the different components (e.g. soil, water,
livestock, etc.)
• Diversification of the production system for dietary
diversification
• continuous cereal mono-cropping
• Policies - national food security on strategic crops e.g.
wheat and not so much on nutrition security,
• subsidies on selected fertilizers, set crop prices, etc.
==substantial reduction in area under legumes
• Challenges in growing legumes
• Biotic (Fungal, foliar, viral diseases; insects and pests,
parasitic weeds) and abiotic (drought, heat, cold and
salinity) challenges in legume cultivation
• Mechanization – manual harvesting of legumes –
uneconomical due to rising cost and shortage of labor
Diversification of production systems

Nutrition
• valuable source of digestible
protein, minerals and vitamins, and
low-glycemic carbohydrate in daily
diet
• 2-3 times more protein than
cereals with complementary amino
acid profile for cereal
• Can be further enriched with
micronutrients through
biofortification of staple crops
• High protein content in straw also
increases milk production
The case for diversification through
increased legume production
Environment
• Break continuous depletion of soil
fertility, and the occurrence of both
persistent and new pests, weeds, and
diseases
• Inclusion of legume varieties improve
soil physico-chemical properties - can
fix 70-210 kg/ha N
• Lowers input requirements and less
pollution with nutrient use efficient
plants
Residue of pulses has a lower C:N ratio
(17) compared with oilseed (41) and
wheat (32)… negative carbon footprint
Legumes (e.g. faba bean, lentils, chickpeas, etc.) have many nutritional,
environmental and economic benefits

Economic
• Currently, the Arab region produces 1.47 million TNs of food
legumes from around 1.60 million ha area (less than 2% to the
global food legumes production (81.8 million tonnes)
(FAOSTAT, 2018).
• Insufficient domestic production to meet local demand -
imports mainly from Canada, Australia and USA
• Rotation, especially with improved varieties of legumes, leads
to higher yield in subsequent cereal crops
• In Morocco rotation with improved faba-bean varieties
led to: 459 kg/ha (48%) higher yields of subsequent
wheat crop, 23.2kg/ha more faba-bean consumption,
and $624/ha (104%) higher net returns (Yigezu et.al 2019)
• provide nutritious feed and forage for the livestock
• Liveweight changes in Ethiopian Arsi-Bale sheep fed
exclusively on Faba bean straws
The case for diversification through
increased legume production (Contd.)

- Tolerance to biotic and abiotic stress –
including pests and diseases, heat, water
stress and quality, marginal soil conditions,
etc.)
- Fetch better market price due to market
specific characteristics like seed size and
color
- Bio-fortified as micro-nutrient rich grains
e.g. good source of Fe & Zn
- produce higher and stable yield
- Varieties that fit in the short season
windows of existing cereal-based systems
Diversification using improved legume
varieties (Examples)
Systematic and concerted research efforts over the years have generated
varieties with wider adaptability

• To diversify production systems to integrate
legumes, increase availability and accessibility of
nutritious foods (dietary diversity) – while
improving system productivity… (Nutrition
sensitive agriculture)
• Investment and research in
• breeding - bio-fortification, resilience (pest
and disease, CC, etc.), mechanization,
marketability, etc.
• Adaptation of legumes to fit in existing
production and food systems e.g. wheat and
faba bean, rice and lentil, etc.
• Engage policy makers and other relevant
stakeholders to promote the nutritional,
environmental and economic case for increased
diversification of production systems for dietary
diversity – generate needed evidence
More needs to be done…
