Prasad S. Thenkabail, an American Citizen, has 23+ years experience working as an well recognized International expert in Remote Sensing and Geographic Information Systems (RS\GIS) and its applications to natural resources management, sustainable development, and environmental studies. Prasad has worked in over 25 Countries in Africa, Asia, Middle-East, and North America.

Over last 4+ years, Prasad is working as a principal researcher of the Global Research Division and Head of the Remote Sensing and Geographic Information Systems (RS\GIS) at the International Water Management Institute (IWMI). Prior to joining IWMI, for 6 years, he was an Associate Research Scientist (a research faculty position) at Yale Center for Earth Observation (YCEO) at the Yale University, USA. Earlier to this, for nearly 5 years, he lead the Remote Sensing programs at the International Institute of Tropical Agriculture (IITA) mostly working in West and Central Africa based in Nigeria and the International Center for Integrated Mountain Development (ICIMOD) working in the Hindu-Kush Himalayas based in Katmandu, Nepal. Earlier to these positions, Prasad worked as a scientist with the National Remote Sensing Agency (NRSA), Department of Space, and Government of India. He started his career as a lecturer in hydrology, water resources, hydraulics, and open channel flow in the Bangalore and Mysore University affiliated colleges in India.

Currently at IWMI, Prasad provides leadership in spatial data applications in various IWMI projects and Thematic Research. The projects he has lead, scientifically, include global irrigated area mapping (GIAM), droughts (remote sensing component), wetland mapping, knowledge base systems for Sri Lanka (KBS-Lanka), and water productivity studies. All projects involve heavy use of spatial datasets, especially satellite sensor data. Prasad has lead developments and launch of following web portals: IWMI data storehouse pathway (http://www.iwmidsp.org), global irrigated area mapping (http://www.iwmigiam.org), and KBS-Lanka (http://www.iwmikbs.org). He has contributed significantly to droughts monitoring system (http://dms.iwmi.org), and tsunami satellite sensor data catalogue (http://tsdc.iwmi.org).

Prasad has 50 publications, mostly peer-reviewed Journals international remote sensing journals. His work on hyperspectral remote sensing of agriculture and vegetation is globally recognized as pioneering work and his publications are widely referenced. He won the 1994 Autometric Award of the American Society of Photogrammetric Engineering and Remote Sensing (ASPRS) for superior publication in Remote Sensing for PhD research related publication on corn and soybean crop studies using Landsat TM data. In Africa, he lead the inland valley wetland characterization and mapping and alternative to slash and burn benchmark area characterization using Landsat and SPOT satellite sensor data. Prasad was on the scientific advisory board of Rapideye, a private German Earth Resources Satellite Company. He played a pivotal role in recommending the design of wavebands in the rapideye sensor onboard a constellation of satellites planned for launch during 2007-08 by Rapideye.

The USGS and NASA selected Prasad to be on the Landsat Science Team for a period of 5-years starting 2006 (http://ldcm.usgs.gov). Prasad is one of the editors of Remote Sensing of Environment and an associate editor-in-chief of the Journal of Spatial Hydrology (JoSH). In June 2007, Prasad's team was recognized by the Environmental System Research Institute (ESRI) for "special achievement in GIS" (SAG award) for their Tsunami related work and for their innovative spatial data portals (http://www.iwmidsp.org) and science applications (http://www.iwmigiam.org). Prasad has won the one of the 5 best papers consistently during 2004, 2005, and 2006 in the IWMI?s annual research meeting and his team was awarded the "best research team" for GIAM work.

I joined the International Water Management Institute (IWMI) in 2002 and currently hold the position of Research Officer attached to the Research Division at IWMI HQ. My main area of work relates to water management research. At IWMI, for the past six years, I have worked on irrigation management issues, wastewater reuse in agriculture, hydrology and the application of remote sensing and GIS for water resource management. My research in the Uda Walawe river basin in southern Sri Lanka contributed to Basin Water Managers arriving at correct decisions to increase irrigation performance, minimize the conflicts that occur between user groups, especially conflicts that arise due to upstream damming that directly affect downstream irrigation. I have quantified wastewater irrigated areas by conducting questionnaire surveys and using secondary information such as maps and figures for 53 cities around the globe. As a result I have been able to learn and understand the diverse techniques adopted in different locations to cope with wastewater irrigation constrains. I have setup, calibrated and validated a Variable Infiltration Capacity (VIC) macro scale hydrological model for the Solani watershed in northern India. I also have experience in meso scale semi-distributed hydrological modelling which I learned in the process of setting, validating and calibrating the Soil Water Analysis Tool (SWAT) for the Solani Watershed in India and the Kulna River Basin in Bangaldesh. In addition I contribute my remote sensing and GIS knowledge and expertise to other IWMI research projects and I am a key player in the RS & GIS lab where I have worked on the IWMI Global Irrigated Area Mapping (GIAM) Project and contributed to the IWMI Data Store House Pathway (DSP).

In October 2007 I participated in a nine month RS & GIS Training Program conducted by the Indian Institute of Remote Sensing (IIRS), Deheradun, India. Upon completion of this Training Program I was awarded the Postgraduate Diploma for RS & GIS and a Gold medal for my superior achievements. In 1999 I graduated Bachelor of Science in Agriculture (four years Special Degree) from the University of Peradeniya, Sri Lanka. During my first degree I studied crop, soil and social sciences, irrigation, hydrology, economics and specialized in agriculture engineering. I completed six months research work on a water balance model for an upstream catchment as a partial fulfillment of the degree. In 2005, I was awarded a Master of Philosophy (Mphil) degree for Agriculture Engineering from the Post Graduate Institute of Agriculture, University of Peradeniya. My Mphil covered the areas of remote sensing and GIS, irrigation and hydrology and also included a wide range of agriculture engineering subjects. This post graduate degree comprised one year of course work and one year of research. For the year of research work I investigated the hydrological regime of a small tank cascade and contributed my knowledge to optimize its irrigation efficiency.

List of major Assignments and Projects (2002 to 2008):

• Hydrological modeling of Solani watershed using macro and micro scale hydrological models. This study was conducted as a partial fulfillment of RS & GIS post graduate diploma. Variable Infiltration Capacity (VIC) model and Soil Water Analysis Tool (SWAT) was applied in one river basin in India and compare the results. Most of the inputs required to the models were prepared using remote sensing and GIS techniques.

• Quantification of Irrigation command using land sat images for Sri Lanka. Under Global Irrigate area mapping project, irrigated area of the Sri lanka was estimated using Land sat images with the help of other secondary information.

• Assessment of Wastewater Irrigation Practices, sanitation and health in selected Cities (50) of less Developed Regions. A survey was conducted around the globe to estimate the wastewater irrigated area and to asses the drivers behind such a usage.

• Study on social conflict due to Kaltota Irrigation scheme. Studied the conflicts occur with down stream and upstream users due to dam a river. Social analysis as well hydrological analysis was conducted to make some suggestion to over come current conflicts.

• Study on social conflict due to Kaltota Irrigation scheme. Studied the conflicts occur with down stream and upstream users due to dam a river. Social analysis as well hydrological analysis was conducted to make some suggestion to over come current conflicts.

• Comprehensive assessment of the Uadawalwe river basin. In this study detail assessment was done to understand the water management opportunities and constrains. Two IWMI working papers and many other conference papers were publish as written out comes.
