  • For Lobell map: Values show the linear trend in temperature for the main crop grown in that grid cell, and for the months in which that crop is grown. Values indicate the trend in terms of multiples of the standard deviation of historical year-to-year variation. ** A 1˚C rise tended to lower yields by up to 10% except in high latitude countries, where in particular rice gains from warming. ** In India, warming may explain the recently slowing of yield gains. For yield graph: Estimated net impact of climate trends for 1980-2008 on crop yields for major producers and for global production. Values are expressed as percent of average yield. Gray bars show median estimate and error bars show 5-95% confidence interval from bootstrap resampling with 500 replicates. Red and blue dots show median estimate of impact for T trend and P trend, respectively. ** At the global scale, maize and wheat exhibited negative impacts for several major producers and global net loss of 3.8% and 5.5% relative to what would have been achieved without the climate trends in 1980-2008. In absolute terms, these equal the annual production of maize in Mexico (23 MT) and wheat in France (33 MT), respectively. Source: Climate Trends and Global Crop Production Since 1980 David B.

  • Why focus on Food security And climate change has to be set in the context of growing populations and changing diets 60-70% more food will be needed by 2050 because of population growth and changing diets – and this is in a context where climate change will make agriculture more difficult.
  • Carbon becomes a commodity, and a profitable one at that. Can smallholders get a piece of the action?
  • Challenge Program then CGIAR Research Program Theme Leaders spread across CG system and the global change community in advanced research institutes New way of working – deliberately networked
  • In a sense all CCAFS work is geared towards enhancing capacity to anticipate and manage different and uncertain climatic futures Capacity enhancement integrated into all themes CCAFS’s comparative advantage is in policy-oriented research So gearing capacity enhancement activities in this area
  • Culmination of perhaps a decade of work but has come out under CCAFS led by Phil Thornton Will generate series/runs of simulated future climate data (daily temperature and rainfall) for any coordinates on the planet These data crucial for e.g. estimating future crop suitability/yields/failures Also have made available set of downscaled climate data sets – strong demand from developing countries and over 200 downloads

  • Andy Jarvis “ Developing Climate-Smart Crops for a 2030 World” Workshop ILRI, Addis Ababa, Ethiopia, 6-8 December 2011
  • The Challenge
  • The concentration of GHGs is rising Long-term implications for the climate and for crop suitability
  • Historical impacts on food security % Yield impact for wheat Observed changes in growing season temperature for crop growing regions,1980-2008. Lobell et al (2011)
  • Average projected % change in suitability for 50 crops, to 2050 Crop suitability is changing
    • In order to meet global demands, we will need
    • 60-70%
    • more food
    • by 2050.
    Food security is at risk
  • Message 1: In the coming decades, climate change and other global trends will endanger agriculture, food security, and rural livelihoods.
  • Left : Example of a silvo-pastoral system 2006 2007 2008 Ecosystem valuation Spot the livestock! Average price in voluntary carbon markets ($/tCO2e)
  • CO 2 Fertilisation
    • Enhanced CO 2 fertilisation, with great potential for some crops
  • Message 2: With new challenges also come new opportunities.
  • Program Design
  • CCAFS: the partnership
    • Identify and develop pro-poor adaptation and mitigation practices, technologies and policies for agriculture and food systems.
    • Support the inclusion of agricultural issues in climate change policies , and of climate issues in agricultural policies , at all levels.
    CCAFS objectives
  • The CCAFS Framework Adapting Agriculture to Climate Variability and Change
    • Technologies, practices, partnerships and policies for:
    • Adaptation to Progressive Climate Change
    • Adaptation through Managing Climate Risk
    • Pro-poor Climate Change Mitigation
    Improved Environmental Health Improved Rural Livelihoods Improved Food Security Enhanced adaptive capacity in agricultural, natural resource management, and food systems Trade-offs and Synergies
    • 4. Integration for Decision Making
    • Linking Knowledge with Action
    • Assembling Data and Tools for Analysis and Planning
    • Refining Frameworks for Policy Analysis
  • Where is the research being done? >> At our 15 CG centers and ~70 regional offices The CGIAR Research Centers Lead center - CIAT
  • Place-based field work Indo- Gangetic Plains : There is risk of heat stress, melting glaciers, and sea level rise; the intensity and probability of extreme events will likely increase. Regional director: Pramod Aggarwal East Africa : Climate change will likely intensify surface and groundwater stress. Regional director: James Kinyangi West Africa : Extreme rainfall variability impedes precipitation predictions, but the Sahel will likely experience shorter growing periods. Regional director: Robert Zougmor é
  • Progressive Adaptation
    • THE VISION
    • To adapt farming systems, we need to:
    • Close the production gap by effectively using current 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
  • Risk Management
    • THE VISION
    • Climate-related risk impedes development , leading to chronic poverty and dependency
    • Actions taken now can reduce vulnerability in the short term and enhance resilience in the long term
      • Improving current climate risk management will reduce obstacles to making future structural adaptations .
  • Pro-poor Mitigation VISION Short-term : Identifying options feasible for smallholder mitigation and trade-offs with other outcomes Long-term : Addressing conflict between achieving food security and agricultural mitigation
  • Integration
    • VISION
    • Provide an analytical and diagnostic framework , grounded in the policy context
    • Synthesize lessons learned
    • Effectively engage with rural stakeholders and decision makers
    • Communicate likely effects of specific policies and interventions
    • Build partners’ capacity
  • Cross-cutting principles, activities & outputs
  • Building a user-driven agenda
    • From large-scale stakeholder consultations
    • e.g. GCARD, regional meetings
    • Specific exercises with selected groups
    • e.g. Venice meeting, regional scenarios, farmer testimonials
    From local to regional to global
  • Mainstream outputs and outcomes For research partners to generate useful data, tools, and results. CLIFF, meteorological services, climate and agricultural research institutes, the Climate Food and Farming PhD student network For policy partners to demand and use data, tools, and results Governments, civil society, development organizations, farmers’ organizations, private sector e.g. User-driven regional scenarios
  • People or organizations increasing their own ability to achieve their objectives effectively and efficiently. A Definition
    • Adaptation requires embedded local capacity, not external solutions
    • CCAFS aims to enhance both (a) research capacities and (b) capacities to link knowledge and action
    The CCAFS Vision Capacity enhancement
    • Social groups differ in (a) vulnerability to climate change and (b) abilities to respond
    • 30% of CCAFS research budget will address gender & social differentiation
    • Early work in gender studies, opportunities for women scientists
    Social differentiation
  • Progressive Adaptation
