1. International Conference on Pulses
For Health, Nutrition and Sustainable Agriculture in Dry Areas
Marrakech, Morocco, 18 - 20 April, 2016
Pulses in Dry Areas:
Importance, Challenges and Potential
Mahmoud El Solh
Director General
ICARDA
2. Outline
Importance of Pulses;
Status of Pulses Production and
Consumption;
Challenges facing pulses production
in dry areas;
What science can do to address
these challenges;
Large scale impact of research
investment;
Conclusion.
4. 3
Great Challenges of Agriculture
• Growing world population
will cause a “serious storm"
of food, energy and water
shortages by 2050
• Demand for food and energy
will jump 70% and 100% and
for fresh water by 30%, as
the population tops 9 billion
• In the past, only ~12 crops
received the major attention
of scientific interventions
The Big Challenge: How to expand agriculture output without further
constraining natural resources?
5. 4
Hungry & undernourished people remains a global concern
• About 1 billion people globally
remain hungry every day.
Many Asian countries
including India is among the
countries with 20-34%
populations undernourished
and categorized as
‘Alarming’ in the Global
Health Index (GHI)
525 million in Asia
undernourished
7. 6
Pulses offer many nutritional benefits
Pulses are three times richer in low
fat protein as compared to cereals
including rice and wheat;
Pulses have complementary Amino
acid profile with cereals;
Micro-nutrient rich grains (Fe, Zn);
Good carbohydrates make pulses a
great functional food;
High in dietry fibre.
8. The Balanced Diet: Cereals with Pulses
The complementarities of cereals & pulses in nutritional value
Food Legumes: High in protein and Lysine, low in sulfur-containing
amino acids:
Protein percentage
Faba bean 20 – 36 %
Lentil 20 – 27 %
Grass pea 25 – 31 %
Kabuli Chickpea 16 – 24 %
Field Pea 20 - 23 %
Cereals/Wheat: low in both protein and lysine but high in sulfur-
containing amino acids

Challenges to Pulse Productivity & Production
Mostly grown under rainfed marginal
conditions: considered as secondary
crops;
Instability in yield: prone to a range of
biotic and abiotic stresses;
Changing climate: emerging new
stresses;
Low yield potential: limited use of wide
range of genetic diversity and desirable
genes;
Use of less inputs by farmers;
Inappropriate supportive policies
favouring cereals production at the
expense of pulses;
Limited access to quality seed of
improved varieties
Low investment in pulses R & D

23. What Science can do to Explore the Potential of Pulses
to Enhance their Productivity and Yield Stability
24. 23
Strategy for Enhancing Pulses Production
• Crop genetic improvement &
new genetic gains for
improved varieties;
• Vertical increase in productivity
through sustainable
intensification of production
systems;
• Closing the yield gaps
• Horizontal expansion
• Reduced post-harvest losses
• 25-60% yield gaps in pulses
• Reasons are many…….
• Closing the yield gaps can alone supply 60% of pulses deficit
• Farmers participatory research

Survived 2007 Excessive Drought in Turkey
The Kabuli chickpea, ‘Gokce’, developed by ICARDA and Turkish
national scientists, has withstood severe drought in Turkey and
produced when most other crops failed in 2007.
Gokce is used on
about 85% of the
chickpea production
areas (over 550,000
ha). With a yield
advantage of 300 kg/ha
over other varieties,
and world prices over
USD 1000/t, this
represents an
additional USD 165
million for Turkish
farmers, in 2007 alone..

How to raise awareness about pulse benefit?
Inclusion pulses benefits in school curriculum among
children;
Innovations in pulse products and ready to eat products;
Messages by celebrities and eminent personalities about
the benefits of pulses in electronic media and print;
National, regional and global events involving
participation of general public and celebrities;
Short documentary films on benefits on pulses.

Recommendations & Conclusions
Pulses for Food Security
Pulses contribute to global food and nutritional security both
directly & indirectly through high protein content.
Major source of micro nutrients
Important source of dietary fibre;.
The protein content of legumes is not as affected by e[CO2] as
cereals & grasses –
Pulses for Environmental Benefits and Mitigation of Climate
Change
Pulse production enhance soil N content and soil productivity
and health;
Production of pulses has lower greenhouse gas emissions than
crops that require N-fertilization;.
Lower fossil energy costs than crops that needs N-fertilization;
77. 76
Recommendations & Conclusions (cont’d)
Pulses for Environmental Benefits and Mitigation of Climate Change (cont’d)
The inclusion of legumes in farming systems appears to accelerate soil C
sequestration promote soil health since it breaks the disease and insect
cycles in soil created by the prevailed cereal mono-culture .
Considering the nutritional and environmental benefits of pulses, it is
essential that pulses consumption is well encouraged;
It is important to bridge the gap between production and consumption at
both national and global levels;
There is an urgent need to invest more in science and technology to
enhancing pulses productivity, production and reduce production cost.
.
The IYP is an excellent opportunity to promote
the consumption of pulses & more investment
in science and Technology to enhance pulses
productivity and production for global food and
nutrition security and healthy soils.
