2. A few definitions
From one of the last documents circulated by the CSA
Alliance:
Climate Smart Agriculture, three pillars
• Sustainably increasing agricultural productivity;
• Adapting and building resilience to climate change;
• Mitigating greenhouse gas emissions.
Distinction between Adaptation and Resilience:
• Adaptation capacity: the ability of humans to deal with
change in their environment (Folke et al., 2004).

3. An empirical example from India
ACIAR project on: Capturing the potential for
greenhouse gas offsets in Indian agriculture
Period under consideration 2010-2050
Essential components are:
• IMPACT model: a global partial equilibrium model of
agricultural commodities
• A spatially-explicit model of land use choices which
captures the main determinants of land use choices
• Crop model (DNDC) to simulate yield, GHG emissions,
and changes in soil organic carbon

4. Data and Simulations
Basic data on output prices (country-wide) and production
costs (state-wide) taken from the Agricultural Statistics,
2013.
Extensive (but not exhaustive yet) search of published,
and not yet published, data on changes in production
costs related to adoption of alternative agricultural
practices.
From DNDC we derive:
• Yields changes
• Carbon dioxide (CO2, from mineralization of organic matter)
• Nitrous oxide (N2O)
• Methane (CH4)
• Soil organic carbon (SOC) accumulation/depletion

6. Simulated Practices
Management
technique Description
Conventional
Prior to first crop in rotation tillage to 30cm depth; subsequent tillages
(following each crop in rotation) to 10cm depth. fertilizer N applied as
urea on plant date; manure applied on plant date
No-till Tillage only mulches residue
AWD
Rice paddy is initially flooded to 10 cm – water level is reduced at rate
of -0.5 cm/day to -5cm and then re-flooded at rate of 0.5 cm/day till to
10 cm
No-till + organic
fertilizer (manure)
Tillage only mulches residue
50% of chemical fertilizer N replaced with organic fertilizer N (manure)

(resilience refers to the production system)
Effects of Adoption of Select Mitigation Practices on
Yields under extreme events
Effects of Adoption of Select Mitigation Practices on
Yield variability
Climate extremes were calculated by considering 97.5
and 0.25 percentiles based on annual precipitation
records for the period of 2004 to 2050 at each pixel.
Then assumed that climate extremes would
be. upper 2.5% and lower 2.5% events at each pixel

15. Conclusions
There seems to be compatibility between CSA
and increased resilience of the productive system,
but….
We first need to fully explore and agree on the
definition of CSA, i.e. boundaries and trade-offs,
The analysis results indicate a large spatial
variability: difficult to make blanket statements of
best practices,
This type of multi-objective analysis becomes
complicated very quickly and it complicates the
formulation of policy recommendations.
