  1. Building capacity to provide useful climate information: Lessons and insights from agricultural decision-making in Argentina Guillermo Podestá University of Miami, Rosenstiel School

  2. Main Points - 1 • An effective climate information system (or climate service) will not develop spontaneously • A climate information system has to be informed and supported by an appropriate researchprogram throughout its initial phase • Research supporting climate information systems must evolve: Exploratory  Pilot  (Semi)operational

  3. Main Points - 2 • Climate information must include a triad of components • Historical data and statistics • Recent climate conditions • Forecasts of regional climate scenarios • False antinomy between research in the natural and social sciences

  4. Funding Sources • Environment and Sustainable Development • Human Dimensions of Global Change • Regional Integrated Science & Assessments • Methods & Models for Integrated Assessment • Biocomplexity in the Environment: Dynamics of Coupled Natural & Human Systems • Initial Science Program – Phase 2

  5. Motivation - 1 • Enhanced technological capabilities • Routine global climate observations • Faster computing capabilities • Better communications, access to data • Better understanding of climate system • Higher awareness of climate influence on some human activities • RESULT: Increased demand for climate information

  6. Motivation - 2 What we expected … Climate Information Societal Use

  7. Climate Information Societal Use What we got … What is a tercile?? Economic conditions It's too coarse! Technology Context How do I use this? People How good is this?? What can I change?

  8. Motivation - 3 • A climate information system has to be supported by an appropriate researchprogram throughout its initial phase (i.e., beyond initial design)

  9. Supporting Research • Projects supporting climate services should evolve through various stages Exploratory Stage Pilot Stage Operational Stage [Hansen, 2002]

  10. Why Argentina? - 1 • Pampas are among the most important agricultural regions in the world • Agriculture accounts for more than half of exports • Argentina-Brazil-Paraguay have increasing weight on soybeans market • Production systems similar to those in US

  11. Why Argentina? - 2 • Marked climate signals • Interannual variability (ENSO-related) • Decadal variability Buenos Aires harbor flooded by aquatic plants from Parana Basin 2002 flood in City of Santa Fe

  12. Research Stages - Exploratory Exploratory Stage Pilot Stage Operational Stage • Associations between climate and agriculture? • Statistical analyses of historical data • Simple modeling • Issue scoping: surveys, focus groups • Partners: academic institutions or governmental research agencies

  13. Historical Maize Yields & ENSO

  14. Modeled Maize Yields ENSO Forecast Forecast Translation Process Models Distribution of Outcomes

  15. ENSO Risk Assessment • What is the range of outcomes of an ENSO event on maize production, given current management?

  16. Exploratory Surveys and Focus Groups • Great interest in climate information • Ignorance about local climatology and “normal” variability • Ignorance about capabilities / limitations of forecasts • 1997/98 El Niño was major turning point in awareness of climate • Importance of context

  17. Research Stages - Pilot Exploratory Stage Pilot Stage Operational Stage • More sophisticated, realistic modeling • Risk management studies • How can we react to climate info? • Economic, social dimensions • Understanding decision-making process • Value of climate information

  18. … High Fertilization … Early Planting Low Fertilization Maize Late Planting … Soybean … Managing Climate Risks - 1 Land Allocation Planting Date Fertilization Rate • OGP-CSI funds: • Decision maps for maize (in press) • Maps for soybean being completed

  19. Climate Scenario A Climate Scenario B … … Managing Climate Risks - 2 Preceding Climate conditions Decision Context Decision Outcomes Agronomic Decisions

  20. Owned Land Rented Land 1/3 Maize 1/3 Wheat Soybean 1/3 Soybean 1/3 Soybean 1/3 Soybean 1/3 Soybean Mapping Realistic Decisions Land Allocation Decisions Almost 50% of agriculture in the Pampas is done on rented land!!!

  21. Mapping Realistic Decisions - 2 • OGP Human Dimensions funding (Weber): Exploration of alternative objective functions • What farmers are really trying to achieve… • Standard economic models often consider only maximization of utility • Wrong assumed objective may imply wrong advice…

  22. Gains Utility Reference Point Income Wealth Losses Mapping Realistic Decisions - 3 Utility Theory Prospect Theory

  23. Mapping Realistic Decisions - 4 Wheat Soybean Soybean

  24. Mapping Realistic Decisions - 5 • Increasingly important role for stakeholders (e.g., farmers and their technical advisors) • Partnerships are first step towards operational status • Difficult to get stakeholders’ “buy-in” • Continuity in interactions (and funding!) • Commitment to produce usable info/knowledge

  25. Strategic Partnerships • AACREA: non-profit farmers’ organization • Groups of 8-12 farmers • About 150 groups in Argentina • “Early adopters” • “De facto” extension functions • Large multiplicative effect

  26. Research Stages – Operational (?) • Research topics: broad spectrum, but highly specific issues • Strategic partnerships crucial: with BOTH operational agencies AND stakeholder groups Exploratory Stage Pilot Stage Operational Stage

  27. Communicating Climate Info • New information is interpreted in the context of existing knowledge and beliefs • Before communicating new information, find out what people know… • What they already know • What they do not know • What they think they know, but is incorrect

  28. “Mental Models” of Climate • Support from OGP-ESD program • Open-ended, free-flowing interview (CMU methodology) • About 60 farmers • Climatically optimal region (Pergamino), long ag history • Climatically marginal region (Pilar), recent ag history

  29. “Mental Models” Results • Local climate is different from that of nearby (50 km) areas • Good yields in better soils are confused with better climate conditions • “Reverse” association between climate experienced and ENSO phase • “If it is a dry year, a Niña must be occurring…” • Opposite ENSO phases occurring simultaneously in different regions • Personal delivery of climate information induces higher trust

  30. Institutional Issues • Support from OGP-ESD program • Role of “boundary organizations” in production/dissemination of climate info • Communication between producers/users • Translation of info (relevance) • Mediation (transparency, legitimacy, credibility) [Cash et al PNAS 2003]

  31. Institutional Issues - 2 • Argentine Meteorological Service • Focused on weather prediction • Lack of links with users (no feedback!) • Unprepared/unfunded to provide climate services • Compartmentalized structure • Multiple bulletins, data products

  32. What we are proposing… • Strategic partnerships with sectoral boundary organizations • Consolidated climate information products • Climatological info • Recent conditions • Seasonal forecasts • “Pyramidal” organization of info Short summary More detail Detailed supporting info Model output, raw data

  33. Climate Information Components Also: “plausible” decadal scenarios, longer scales?

  34. Why historical information? • Lack of knowledge about local climatology • What is “normal”? • Recent arrivals to agriculture • Greater memory of recent events • How to interpret seasonal forecasts • Boundaries between terciles?

  35. Why diagnostic information? • Provides context for decision-making • Refine previously-made decisions • Helps interpret forecasts • Relevant span is sector-dependent

  36. Summary - 1 • An effective climate information system (or climate service) will not develop spontaneously • A climate information system has to be informed and supported by an appropriate researchprogram throughout its initial phase • Research supporting climate information systems must evolve: Exploratory  Pilot  (Semi)operational

  37. Summary - 2 • Climate information must include a triad of components • Historical data and statistics • Recent climate conditions • Forecasts of regional climate scenarios • False antinomy between research in the natural and social sciences
