The main agricultural areas of Chile will face a significant reduction of rainfall (between 20-40%) due to the global climate change. Also, Chile is periodically affected by the climatic phenomenon of “La Niña” (ENSO), which has produced important droughts and economical losses in most of agricultural areas. However, Chilean farmers do not have modern tools to estimate the crop water requirements or actual evapotranspiration (ETa) of orchards and vineyards for improving water management and water use efficiency, especially under droughts. In this regard, the objective of this seminar is to describe an irrigation management system for improving water use in vineyards and olive orchards using meteorological information in combination with remote sensing data. The description includes the development of a methodology to generate maps with spatial distribution of crop coefficients (Kc) and ETa of vineyard and oil olive orchards. Also, the presentation will describe a preliminary study about the use of optical remote sensors on board an unmanned aerial vehicle (UAV) to estimate olive ET at high spatial and temporal resolution.
Dr. Samuel Ortega-Farias obtained a Bachelor of Science degree in viticulture and enology at the Catholic University of Chile. He obtained a Master and a Ph.D. degree from Oregon State University, working on irrigation management and evapotranspiration modeling. He is currently working as a professor of irrigation and agroclimatology at the College of Agricultural Sciences, University of Talca (Chile). In the same University, he also is the Director of the Research and Extension Center for Irrigation and Agroclimatology. His research has focused on regulated deficit irrigation in vineyards, evapotranspiration modeling using remote sensing, and water footprint and sustainable irrigation management.
