Agriculture in the drylands & sustainable desert agriculture
The goal of sustainable agriculture in arid and semi arid regions is challenged as farm management needs to address needs of crops under often harsh conditions. Plants growing in the more arid areas confront a number of abiotic stress causing factors including drought, extreme temperatures, high winds, low humidity, high radiation, salinity and specific ion toxicity. These factors become tangible both as direct physiological stresses in the plants and indirectly, via altercations to the physical environment. The session will provide a platform to understand and discuss some of the dominant abiotic stress causing factors in context with desert agriculture and to investigate methods to contend with them sustainably.

Professor Robert Lascano
Cropping Systems Research Laboratory, USDA-ARS
Title of Abstract:
Calculation of Water Evaporation in Arid Climates
Show Biography
Dr. Lascano has taught a graduate level class on soil-water-plant relations at Texas Tech University, since 1994 and has served on a graduate committee of more than 20 students and supervised 12 M.S. and 12 Ph. D. students as an Adjunct Professor at Texas Tech University Texas A&M University, and Wageningen University.
In the past Dr. Lascano has worked on the water balance and hydrology, micrometeorology, irrigation management, soil-water measurement, computer modeling and simulation, in relation to agronomy and crop production in semiarid agriculture. Dr. Lascano has published a mechanistic model that calculated the partitioning of evaporation of water from the soil and the crop and ways to reduce water evaporation from the soil surface as means to increase crop transpiration. Dr. Lascano has also worked on site-specific management of cotton at a landscape scale and showed that cotton lint yield across the landscape could be calculated using state-space analysis from soil water supply, elevation and nitrogen. High cotton lint yield is predicted in lower elevations of a field that favor accumulation of water and nutrients and reduce loss of water through evaporation. Lower cotton lint yields will be on the slope and the plateau, where the soil is susceptible to loss of water, organic matter and nutrients through erosion. The state-space analysis reflects weight of contribution of underlying variable to explain crop yield variability. More recently, Dr. Lascano has worked on a recursive calculation of crop evapotranspiration that uses as iterative solution to calculate the surface temperature that satisfies the energy balance of the evaporative surface. The theory was developed and tested by comparing measured and calculated values of crop evapotranspiration. It is shown that this method is physically accurate and that the traditional Penman-Monteith equations used for crop irrigation are in error.
Dr. Lascano has published more than 75 refereed journal publications, 26 Texas Agricultural Experiment Station Miscellaneous Publications, 55 Conference Proceedings, 2 book chapters, was co-editor of the Irrigation Monograph, 17 invited
papers, and three computer software models with user's guides.
