After nearly 10 -productive years as a lead climatologist and ecologist at the International Institute of Tropical Agriculture (IITA), Nigeria, I have now joined the University of Florida where I conduct applied research on climate forecast, global warming, and climate change impact on agriculture. Here are some of the things I've recently accomplished:

¨ Member of a multi-university and stakeholder consortium that developed products to provide climate forecast information and economic risk management products for agriculture and forest wildfires.

¨ Lead author on two recently concluded US national studies on impact of global warming and climate change on crops productivity looking at the risks and opportunities.

¨ Lead author of report on climate change impact on Agriculture for the National Resource Defense Council and Atlanta Journal of Constitution

Before returning to the University of Florida in 1998, I worked at the International Institute of Tropical Agriculture (IITA) as a principle climatologist, ecologist and head of Agroecological Studies Unit at IITA. As the key-scientists for IITA’s climate and ecological research, my achievements included:

¨ Launching a global activities on geo-referencing and mapping IITA’s genetic resources and linked them to GIS databases. This remarkably improved IITA’s capability of distributing improved seeds throughout Africa, and successfully targeting resource management technologies to solve specific problems.

¨ Installed natural resource knowledge management systems throughout West Africa, and was responsible for providing technical and strategic leadership for development of sustainable initiatives/projects. One of such initiatives, Inland Valley Consortium established in 1992, is still functional on external donor funding.

¨ Solicited, negotiated and managed several project to inventory natural resources in West Africa, document evolutionary trends in agricultural systems, and advised students who conducted integrated climate change policy related studies. The databases developed lead to the definition of agroecological zones and identification of the Benchmark Sites in the ecoregional programs conducted by IITA in West Africa.

¨ As a past president of the Nigerian Meteorological Society, I successfully organized professional to debate and documents climate change impact on agriculture.

Prior to joining CGIAR in 1989, I was a member of an international group of research institutes and universities that were involved in the development of tools to study impact of global warming and climate change on crops.

¨ Conducted pioneering research on crop responses to varying levels of carbon dioxide ranging from 160 to 990 parts per million, which lead to the development of predictive models for water consumption as well as crop production.

¨ Contributed to the developed a tool-kit consisting of crop yield simulation models, risk analysis and weather generator – known widely as the Decision Support System for Agrotechnology Transfer (DSSAT). DSSAT allows assessment of contribution of agricultural technologies in a transparent manner to enable farmers to be more productive.

¨ I have authored and co-authored over 140 publications on sustainable natural resource management, production agricultural assessment, biodiversity, global warming and climate change, risk analysis, and statistical data mining. In addition, I have held teaching and research positions at the University of Hawaii, University of Florida, and several community colleges in the USA.

¨ I received Ph. D. from the University of Florida (1986), M.S. from the University of Georgia, and B. Tech from the Indian Institute of Technology, Kharagpur. I am a member of several professional societies, and serves as reviewer for many scientific publications and books.

Professional Career

· 2002-Present Visiting Scholar (Uni. of Florida): Plan and conduct multidisciplinary research on the applications of the El Niño/Southern Oscillation and its influence on crops and nutrients, the analysis and display of climate information, the influence of uncertainty in environmental inputs on regional crop yield predictions and the impact of global climate change on agriculture. I play significant research role in SECC efforts to efficiently utilize climate forecast produced by the Florida State University’s coupled global and regional climate models with crop models, through maximizing the accuracy of the forecasts, streamlining and automating the utilization of forecast, and facilitating the creation of seasonal crop outlook tailored to specific crops and regions within the SE USA. These activities are expected to lead to developing decision analysis framework to promote integrated crop management practices that can reduce vulnerability of the society from climate related disasters.

· 1998-2001 Visiting Scholar (Uni. of Florida): Conducted research on climate change impacts on crops and water resources. It involved a detailed assessment of projected climate change on agricultural productivity and water requirements in the SE USA and a semi-detailed one for the entire USA. Several key data and methodology issues were identified as key constraints in predicting agricultural responses to climate variability
