1 billion…
… hungry
.. obese
…tons/year wasted!

Challenges to food security
• Chronically hungry: 870 million in 2012
• Global population of over 9 billion by 2050 – 70-100% increase food production by 2050
• Declining water & land per caput (4.3 ha
(1961) to 1.6 ha (2050))
• Lower productivity growth & production
stress from climate change
• Rapid urbanization & change in
consumption patterns
Challenges to food security
• Increase intensification of production – 80% from land already under cultivation
• Green Revolution – Major gains but…
– Not sustainable or sufficient
• Challenge: How to intensify crop production
and do this in a sustainable manner?

The Way to Go: Save and Grow
• In Asian rice production:
– Land is moving out
– Labor is moving out
– Water is moving out
• Major changes in crop production/protection practices and increases in efficiency needed!
• In order for rice production to grow, farmers will need to learn how to save!

Sustainable Intensification of Crop Production
Ecosystem approach
• external inputs complement natural
processes and ecosystem services:
– natural biological control
– improve soil fertility & H2O holding capacity
– nutrient cycles and better up-take
– pollination
Sustainable agricultural systems:
Ecosystem-literacy training for
smallholder farmers is vital!
Save and Grow
Four underlying principles
1. enhancing productivity and profitability
2. increased resource use efficiency
3. ecological sustainability
4. climate-smart, enhancing resilience
Management practices and technologies 1. Conservation agriculture
2. Integrated Pest Management
3. Fertilizers & Integrated Nutrient Management
4. Improved crop varieties
5. Water Saving methods
6. Crop Diversification and Rotations
14
Conservation Agriculture
Minimum tillage => Permanent Soil Cover
Eliminates erosion, improves degraded soils
Increases soil organic matter and structure
Reduces water + fertilizer needs by 30%
Pesticide use reduced by 20%
15
Conservation Agriculture
Climate change mitigation
Reduces green house gas
emissions
reduced energy needs by
60%
more efficient use of inputs
(N2O, CH4)
Sequesters carbon – 200
Kg/ha/year
16
Integrated Pest Management
Improved control of pests and diseases
with reduced use of pesticides
Promotes:
Healthy environment
Effective ecosystem services
Stable and high yields
Higher profits for farmers
Food safety
Rice Integrated Pest Management:
• Conservation of Natural
Biological Control
• No need for Insecticides
• Growing a healthy crop
• Regular field scouting for
informed management
• Farmers as IPM Experts!

Fertilizers
• 50% of increased food production
• Price increase 2-3 fold since 2006

Management – what
when and how much

Rice production
•500,000 farmers in
Bangladesh
• 60% reduction in the
amount used
• reduced pollution and
gas emissions (N2O)
• 25% yield increases

Improved crop varieties
• 50% of yield increases
due to improved
varieties
• more efficient use of
water, fertilizer
• tolerant to drought,
flooding, higher
temperatures and pests
Water is Essential cannot produce food without water but we can produce
food with less water
Water is Essential “more crop per drop”
More efficient use
• Improve existing irrigation
structures and
management
• Adopt more efficient
technologies
• Water harvesting
• System of Rice
Intensification: alternate
wet and dry water
regimes or keeping soil
preferably moist during
vegetative stage
According to IRRI - without reducing yields, use of SRI:
• reduces water consumption by 30%
• reduces greenhouse gas emissions by 25-50%
“Rice is so important across the whole of Asia that if one could implement this technology in many different places, you could have significant reduction in methane production.” Campbell, coordinator CGIAR Climate Change Research Task Force
Save and Grow: System of Rice Intensification
In Vietnam summer crop 2011, SRI was
applied on 185,065 hectares in 22 provinces
by over 1,070,384 farmers (69% female)
In Cambodia as of 2011, SRI was applied
on 24,293 hectares in 13 provinces by about
75,395 farmers
Paddy fields in East Java, hit by both brown planthopper (BPH) and tropical storm damage in June 2011
New variety (Ciherang) with fertilizer & agrochemical protection – no yield
Traditional variety (Sintanur) with organic SRI management – 8 t/ha yield
Crop diversification: growing
potatoes after rice
Optimizing the use of remaining
moisture in the rice field - and the
practice of mulching - reduced
irrigation from 5,000 cubic meters
of water to 900 cubic meters per
hectare
Cultivation using minimum tillage
potato IPM has the potential to
reduce labor costs by 45%
compared to the conventional
method
Profits from growing potatoes
increased by 60 to 73%

Maximizing the benefits of
more efficient production 30-40% of food produced is lost or wasted
• primarily at farm level in
developing countries
• improved food security,
increased income – better
nutrition and stability
The use of metal silos to store grain and maize can
reduce post-harvest losses.
Farmers Field School
“School without walls”,
farmers learn about crop
ecology and pest
management in the field;
Season-long, from seed
to harvest, 25-30
farmers;
Aim to help farmers
adopt IPM, grow healthy
crops and produce more
& safer food with less
inputs of agro-chemicals
Farmer Field Schools
Farmers acquire: –Observation skills –Analytical skills –Decision-making skills
FFS are particularly suited for learning complex management skills, like natural resource management, diversifying production and accessing markets to increase rural incomes (Swanson and Rajalahti, World Bank, 2010).

The way forward • We can produce the food needed by 2050 in a
sustainable manner
• No silver bullet solutions – approaches need to be tailored to individual country needs.
• Increasing production alone is not sufficient – Innovation & investment along the food value chain is required.
• Sustainable production is knowledge intensive – investments in agricultural research, development and capacity building for ecosystem-literacy training are essential.
• Today’s rural youth will be the farmers of tomorrow: Include discovery-based field training on ecology and exploring agro-biodiversity in formal school curriculum!
