Climate, Drought, and Agricultural Adaptations: Vulnerabilities and Responses to Water Stress Among Paddy Farmers in Sri Lanka Josh Bazuin, Amanda Carrico, James Fraser, Jonathan Gilligan, John Jacobi, George Hornberger, Lanka Thabrew, Heather Truelove
Drought Adaptation? • How do psychological, social and institutional factors affect farmer adaptation decisions? • How do changing climate patterns, land use, and water allocation decisions affect water availability and rice yields? • How might future changes in the natural environment and social & institutional circumstances affect farmers' vulnerability?
Natural science variables • Rainfall • Temperature • River flow • Reservoir storage • Forest cover • Land for cultivation • Social science variables • Risk appraisal • Coping appraisal • Social appraisal • Adaptive and behavioral responses ABM – scenario analyses Water Availability Rice Production
A multi-level, multi-method approach • A natural quasi-experimental setting • differing communities analyzed • Drought analysis methods • Archival analysis and key interviews • characterize political decision making • Agent based modeling • integrate multiple streams of data • generate a set of possible scenarios
Drought and Rice Production in Sri Lanka • Two growing seasons • Maha (Sep – Mar) • Yala (May – Aug) • PDSI was calculated for each growing season in four rice producing districts Trincomalee Dry Matale Intermediate Wet
Drought and Rice Production in Sri Lanka • Correlation between PDSI and rice production was found in Trincomalee - Yala • Trincomalee is dry and at the end of the irrigation line R = 0.51 P = 0.02
