James W. Hansen

Dr. Jim Hansen holds a Ph.D. in Agricultural and Biological Engineering from the University of Florida, and an M.S. in Agronomy and Soil Science and B.S. in General Tropical Agriculture from the University of Hawaii. Jim leads CCAFS Climate Risk Management Flagship, which advances interventions that enable farming communities, and the institutions that support them, to become more resilient in the face of climate variability and extreme weather events. The Flagship's research focuses on: (a) climate-based seasonal agricultural prediction, early warning and decision support; (b) knowledge and methods for equitable climate information and advisory services for smallholder communities; (c) food security safety nets and policy interventions for dealing with impacts of climate-related shocks; and (d) weather-related agricultural insurance.  He is based at the International Research Institute for Climate and Society (IRI), at Columbia University, New York, where he is a Senior Research Scientist. 

Jim has been involved in CCAFS since early 2008, when he served on the Leadership Group that developed the successful proposal to create CCAFS as a CGIAR Challenge Program.  He then joined the CCAFS management team in 2009 as Leader of the Research Theme on Adaptation through Managing Climate Risk, which sought to enable promising innovations for managing climate-related agricultural risk – at the local scale of farms and rural communities, and at the level of governments and food security humanitarian organizations that intervene when a climate shock exceeds the coping capacity of rural.  His role shifted to Flagship Leader as CCAFS entered a new phase.

Jim has worked on managing climate-related risk for agriculture and food security since 1996 – first at the University of Florida where he was part of the Southeast Climate Consortium, then since 1999 in his present position as a researcher at the International Research Institute for Climate and Society (IRI).  His involvement in CCAFS has lead him to be increasingly concerned with: (a) how resilience framing can inform interventions that address both climate change adaptation and immediate development challenges in high-risk smallholder farming environments; and (b) finding practical, equitable and scalable solutions to the challenges of making smallholder livelihoods more resilient through climate services, climate-related insurance, and climate-informed food security management.  

Past research contributions have included integrating climate information with agricultural modeling; the economics of risk and advance information in agriculture; developing effective climate information services for farmers; farm economic risk and sustainability analysis; spatial scaling in agroecosystem modeling; stochastic weather modeling; and modeling multiple cropping systems. 

Other professional contributions include: serving as Co-Editor-in-Chief of Agricultural Systems (2002-2010)serving on the team that coordinated and reported the multi-stakeholder Gap Analysis for the Implementation of the Global Climate Observing System Programme in Africa which contributed to development of the ClimDev-Africa program; the International Review Team for Australia’s Managing Climate Variability R&D Program; and the Steering Group for the international Climate Prediction and Agriculture (CLIMAG) Program of ESSP.
