1. Climate-smart agriculture (CSA):
Panacea, propaganda or paradigm shift?
• We are conducting a systematic review and meta-analysis to
evaluate the evidence base for CSA.
• More than 144,500 abstracts of journal articles have been
reviewed, of which, 6,741 papers met our inclusion/
exclusion criteria making this the largest agricultural meta-
analysis attempted.
• Geographic clustering of research and a lack of co-located
multi-objective research leaves gaps in the evidence base
and dictates the need for new paradigm for CSA research.
• Evidence of variable impacts of practices on CSA objectives
and synergies and tradeoffs between objectives indicates the
need for careful selection of practices when scaling up CSA.
• Data will be publically available in a Web-based database
later in 2015.

Standard meta-analytical approach: Response ratios
(RR) and Effect sizes (ES). RR = ln(mean(XT)/mean(XC)).
ES = weighted mean of RRs based on number of reps.

Left. Effect of select aggregate management
measures on yield (ln 0.5 ≅ Δ60% between
CSA and control). Figure shows clear
benefits of select CSA but variability, within
and among practices, in effect size suggests
potential for context-specific outcomes.

Right. Potential synergies and trade-
offs from CSA from co-located
research. In this graph, based on
comparisons from a randomly selected
sample of 55 studies, more than 60%
showed trade-offs among adaptive
capacity and productivity, versus 32%
showing synergies.

Only 1% of studies contain data relevant
to all three CSA’s three objectives from
co-located research.
Research is geographically clustered
around highly research locations,
leaving potentially significant gaps in
knowledge base.
