2. Outline of the Presentation
• The what and Why of Sustainable
Intensification(SI)
• The Problem Setting
• CIMMYT’s and its partners Response: SIMLESA
• SIMLESA First Five Years Journey: Lessons and
Insights
• Take Home messages

3. The problem setting
Low productivity Scarce biomass Land degradation
Poor marketsClimate variability Limited resouces

4. What is SI?
• Sustainable intensification (SI) means
producing more output from the same area of
land while reducing the negative environmental
impacts and at the same time improving natural
resources and environmental services.
• Sustainable intensification is receiving growing
attention as a way to address the challenge of
feeding an increasingly populous and resource-
constrained world

5. Sustainable Intensification
Sustainability
•Conserve the natural
resource base (Godfray et al.,
2010; Pretty et al., 2011; Tilman et al., 2011)
•Ecologically and
technically sound eg soil
quality degradation through erosion,
fertility decline
•Socially and Culturally
acceptable ( Do the technologies
fit local farming systems?)
•Economically viable (does
it make economic sense?)
Intensification
•Increased yield or outputs per
unit area/inputs (Enhance
productivity)
•Diversification from maize for
diet diversification and improved
incomes
•Integration of crops & livestock
•Improved resilience to market
shocks and climate risks
•Improved efficiency per unit
input eg water, labour, capital,
inputs
Improved food security and livelihoods

6. Why SI
The use of sustainable intensification in current debates is
based upon three fundamental assumptions about
agricultural production systems in the 21st century(iied,2015)
• The world must produce significantly more food in the
coming decades to feed a growing, increasingly affluent
population.
• The arable land base cannot be expanded significantly.
Agricultural production must preserve the natural capital
on which sustainable and resource use efficient to
agriculture relies.

7. Rationale for Investing in SI
(John Dixon ACIAR 2014)
The pressure on land, water and energy
resources was reflected in increasing prices, for
example the crisis in 2008. The declining real
prices during the 1970s, 1980s and 1990s led to
complacency and neglect of public and private
investment in agricultural innovation.
A commitment to sustainable intensification is
the best way to turn this around

9. SIMLESA Enhancing Integration,
Innovation and Impact
Vision of Success
• To increase maize and legume yields by 30% while
sustaining the environment through:
• Conservation agriculture practices
• Improved maize and legume varieties
• Development of markets and value chains, from input
supplies to output markets.
• To reduce downside yield risks by 30%
• To benefit 650,000 farm households within 10 years.

11. System integration:
Diversification through Cereal (Maize)-Legume Integration
Legumes
• Increase soil fertility
• Improved nutrition
• Supply cashCereal (Maize)
• Increased productivity
– Ensured food security
– Income security
-Increase productivity
-Increase profitability
-Reduce down side risk
Forage
• Alternative of cattle
feeding (residue
management)
• Improved animal
nutrition

12. The SIMLESA journey

2010 – teams, field sites, capacity building
2011 – ARPM, Nairobi
2012 – ARPM, Arusha
2013 – ARPM, Chimoio
2014 – ARPM, Addis Ababa
Start of SIMLESA II
2015 – ARPM Harare

13. SIMLESA I (2010 – 2013)
Made considerable progress in each
of the target countries
Ethiopia,
Kenya
Tanzania,
Malawi
Mozambique
‘Steady flight path’

14. SIMLESA I (2010 – 2013)
• Characterization of maize-legume
production and value chain systems;
• Testing of promising smallholder
maize-legume cropping systems;
• Increasing the range of maize and
legume varieties available for
smallholders;
• Developing regional and local
innovations systems;
• Substantial capacity building of
agricultural research partners

15. 1. Strengths of SIMLESA-1
• considered as a model for Effective partnerships
-NARS and other major donors’ testimonies
• Multi-stakeholder
• NARS empowered and enabled to make good amount of operational
decisions on program activities and thrust
• NARS receive a relatively higher funds compared to other projects
• Joint data ownership with NARS
• Developed good collaboration and partnership arrangements between
CIMMYT and NARS based on trust and respect between players
• NARS empowered and enabled to make decisions on program activities
and thrust
• Joint presentations and development of publications between CIMMYT
and NARS

16. • NARS participation at high Profile conferences and
congresses- paper and poster presentations-
• Journal articles published
• 5th World Congress on CA -Brisbane, Australia -2011
• 6th World Congress on CA Winnipeg ,Canada June 2014
• International Agronomy Conference-India 2012
• International Agricultural Economics Conference, August
2012 Brazil
• Other country and regional meetings( IACAC, AGRF, FARA..)

23. Key lessons
• Link farm production with better
domestic value chains, often the first
step in international trade opportunities
• Focus on competitiveness, driven by
increased productivity as well as
efficient value chains
• Engage agribusiness from the start in
order to understand market forces, risk
and research priorities

24. Key lessons
• Integrate value chains activities with
technologies, capacity building and
local policy analysis, in innovation
platforms
• Consult women during project design
and implementation
• Understand the incentives of all chain
members and value chain dynamics
within the broader market and trade
context

25. Take home messages
Four critical aspects of SI which require particular attention:
• systems research and development – beyond disciplinary
components;
• innovation systems bridging research and scaling out;
• policies, institutions and business partnerships; and
• monitoring and evaluation of sustainable intensification
systems.
