The climate analogues approach

The Challenge

Page 4: CCAFS The Analogues Approach to Climate Change Adaptation

4 • 3/21/11

Problems/Opportunities

Problem: 60-70% more food to support a growing population….

…..under an uncertain and potentially unfriendly climate

Countries and communities asking: What does climate change imply, what can I do to adapt, how much will it cost, how do I implement it?

Opportunity: Massive amount of existing knowledge on technologies and practices for production, and increasing food system governance from local to global level

Exacerbating the yield gap

From Licker et al, 2010

Climate change will likely pose additional difficulties for resource-poor farmers (e.g., in Africa), thereby increasing the yield gap

Exacerbating the yield gap

Climate change will likely increase difficulties for resource-poor farmers, thereby increasing the yield gap

Progressive Adaptation

THE VISION

To adapt farming systems, we need to:

• Close the production gap by effectively using technologies, practices and policies

• Increase the bar: develop new ways to increase food production potential

• Enable policies and institutions, from the farm to national level

Other Crops

Structural Adaptation

Action: Common Code for the Coffee Community (C4) introduces an add-on climate module that would indicate when coffee producers have adapted their production system to a changing climate.

Result: Retailers agree to buy only C4-certified “climate-proofed” coffee. Accordingly, changes occur down the coffee supply chain, with collaborative efforts to create a more adaptive structure.

Adaptive Adjustments

Action:a) Shadingb) Changing varietalsc) Changing inputs

Result: Improved risk management at the farm level, allowing for long-term adaption.

Transformational Adaptation

Action: Migrate to keep farmingChange farming systems (agricultural)Switch livelihood sources (non-agricultural)

Result: Long-term adaptation, but requires significant up-front transition costs.

Effect of +1ºC warming on yield

Sites with >23ºC would suffer even if optimally managed

More than 20% loss in sites with >20ºC, under drought

Importance & Potential • Collating input climate and

agricultural data• Design of experiments• Calibration, validation and crop

model runs• Exploration of adaptation options

– Genetic improvement– On-farm management practices

• Test them via modelling• Build “adaptation packages”• Assess technology transfer options

Next steps with Agtrials

• Continue to develop the infrastructure for sharing trial and evaluation data

• Analyse data in agtrials: GxE analyses at crop and variety level

• Continue to populate with data – the more data, the better our understanding of varietal level adaptation, GxE etc.

Farmers’ Network for Participatory Evaluation

Goal: To improve farmers’ access to knowledge and genetic materials; and build their experimentation skills– More than 70 farmers’

field trials at 4 project sites in IGP

– Farmers selected varieties based on their perspective

It links farmers’ realities on the ground with promising scientific research outputs, to inspire new ideas and highlight current challenge.

Why is it useful?

The Climate Change Adaptation and Mitigation Knowledge Network platform is a portal for accessing and sharing agricultural A&M knowledge.

>> Spotlight on: Farms of the future

The climate analogue tool identifies the range of places whose current climates correspond to the future of a chosen locality

What CCAFS output?

The Analogue Concept

• We heavily rely on models to tell us what the future holds– GCM/RCM projections– Crop models, household models,

farming system models

• Few take into account human adaptive capacity, and social and cultural factors that contribute to decision making

Page 30: CCAFS The Analogues Approach to Climate Change Adaptation

30 • 3/21/11

Novel climates• Williams et al. (2007) state that

there is likely to be 30% novel climates under climate change

• That means that there are 70% of already existing climates projected to 2100 for sites!

• Analogues: Use spatial variability in climate as a means of having a real experiment of what the future holds for a site

Page 31: CCAFS The Analogues Approach to Climate Change Adaptation

31 • 3/21/11

Benefits of an analogue approach

• Large uncertainties remain regarding future projections of climate, and their resultant impacts on farming systems, especially at the local level.

• The adaptive capacity of communities is a factor rarely taken into account in the global/regional models on which policy makers often rely

• The use of climate analogues for locating future climates today can ground models in field-based realities, significantly enhancing our knowledge of adaptation capacity and supporting the identification of appropriate interventions.

Why we think this an important approach

• Facilitating farmer-to-farmer exchange of knowledge

• Permitting validation of computational models and trialing of new technologies/techniques

• Learning from history

- CCAFS site- 600 mm annual rainfall- Min. Temp. 14.8°C - Max. Temp. 39.1°C

- Main crops:- Millet- Maize- Peanuts- Sorghum- Sesame

-Climate Change threats:

The Model: EcoCrop

It evaluates on monthly basis if there are adequate climatic conditions within a growing season for temperature and precipitation…

…and calculates the climatic suitability of the resulting interaction between rainfall and temperature…

• So, how does it work?

High climate similarity

Where can we find a region with similar climatic conditions to Kaffrine, Senegal in 2030?

Climate similarity

Conclusions and a word of warning

• We believe the analogue approach as an interesting tool for analysing impacts and identifying and supporting adaptation strategies

• You are the first to see this, and there are still some glitches, plus we continue to improve methods based on calibration and validation

• We’re interested in feedback, suggestions for improvement, and working with you in the use of the tool to continue its improvement
