Where the bar shows yield gap fractions, so green (0) = no gap between actual production and potential production; and red (1) = complete yield gap.
ANIMATED SLIDE. Example of systemic adjustments vs. structural adaptation with the coffee supply chain. Shading is one example of an adjustment, whereas larger scale, transformational, “structural adaptation” requires larger changes, which in this case can occur via certifications of climate-proofed coffee (C4 label). This creates an incentive for retailers and federations to invest in more sustainable coffee production (e.g., organic) and more resilient inputs (e.g., certain varietals). The result is adaptive change all along the supply chain.
Need to link those with objective 1.1; 1.2 and 1.3 somehow …!!!
IGP is food basket of South Asia. Climate change threatens wheat and rice production in the IGP due to heat stress as well as irrigation uncertainties. This experimental network has advantage for researchers as well as farmers. RESEARCHERS, project provides on-farm data and visualization of how different varieties fare. Also allows for synthesis of farmers’ local knowledge and varietal preferences. For PARTICIPATING FARMERS, helps improve stocks of adaptive varieties in their local seed systems, and better knowledge to share via farmers’ experimentation networks Projects located in 4 states across the IGP: Haryana, Punjab, Bihar, Uttar Pradesh
The current suitability is closed to 100% because we are only using a range of temperature and precipitation and we don’t consider other parameters as soil,…. We did the ecocrop analysis with the average of annual precipitation and not with taking in account the crop seasonnality (which could be more exact).
Maybe this slide is not really usefull because we want to compare the current climate of Niger with the future climate of Senegal then it is not crucial to know the future climate of Niger.
Intro climate analogues approach - Andrew Jarvis
The climate analogues approach Concepts and application
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
0 0.25 0.50 0.75 1 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 <ul><li>THE VISION </li></ul><ul><li>To adapt farming systems, we need to: </li></ul><ul><li>Close the production gap by effectively using technologies, practices and policies </li></ul><ul><li>Increase the bar : develop new ways to increase food production potential </li></ul><ul><li>Enable policies and institutions, from the farm to national level </li></ul>
Input Providers Consumer 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) Shading b) Changing varietals c) Changing inputs Result: Improved risk management at the farm level, allowing for long-term adaption. Wholesale/Retail C4 Coffee Federation Coffee Producers a) Shading
Coffee Producers Transformational Adaptation Action: Migrate to keep farming Change farming systems (agricultural) Switch livelihood sources (non-agricultural) Result: Long-term adaptation, but requires significant up-front transition costs.

The Analogue Concept <ul><li>We heavily rely on models to tell us what the future holds </li></ul><ul><ul><li>GCM/RCM projections </li></ul></ul><ul><ul><li>Crop models, household models, farming system models </li></ul></ul><ul><li>Few take into account human adaptive capacity, and social and cultural factors that contribute to decision making </li></ul>
Novel climates <ul><li>Williams et al. (2007) state that there is likely to be 30% novel climates under climate change </li></ul><ul><li>That means that there are 70% of already existing climates projected to 2100 for sites! </li></ul><ul><li>Analogues: Use spatial variability in climate as a means of having a real experiment of what the future holds for a site </li></ul>
Benefits of an analogue approach <ul><li>Large uncertainties remain regarding future projections of climate, and their resultant impacts on farming systems, especially at the local level. </li></ul><ul><li>The adaptive capacity of communities is a factor rarely taken into account in the global/regional models on which policy makers often rely </li></ul><ul><li>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. </li></ul>
