Severe droughts have plagued the United States over the last few years. The 2011 Texas drought, the 2012 U.S. drought, and the current California drought have greatly impacted the nation's economy and agricultural production. Different crops vary in their response to water stress. Despite this, commonly used drought indices, such as the Palmer Drought Severity Index, do not consider crop specific factors. The goal of this project was to create a methodology to produce crop and location specific drought and yield trend forecasts to help agricultural producers make more informed water management decisions. To achieve this, a drought index was developed and analyzed, weather forecasts were used in a hydrology/crop model to predict hydrologic conditions and crop yields, and an example interactive map interface were created to convey this information to water stakeholders. The drought index uses five parameters that affect or are affected by drought. These parameters include precipitation, temperature, cumulative biomass, soil moisture, and transpiration. Soil moisture and temperature are ranked against crop-specific threshold values, while precipitation and cumulative biomass are ranked against location-specific normal values. Transpiration is ranked against the location-specific potential transpiration. A case study was performed in the Upper Colorado River Basin located in West Texas using this drought index. Cotton is the primary crop grown in the watershed and was used in this study. The Soil and Water Assessment Tool (SWAT) was used to estimate the cumulative biomass, soil moisture, and transpiration. A multiple linear regression model was developed for each week of the growing season based on the significant parameters during that stage of the growing season. These models were used to predict yield trends and drought severity. Two week forecasts for each drought parameter, yield trends, and the drought index were generated for 2010 through 2013 by using forecasted precipitation and temperature data as inputs for the hydrologic and crop model. This provided forecasted soil moisture, transpiration, and cumulative biomass production. Parameter rankings, yield trends, and the drought index were compared for those calculated with actual precipitation and temperature data as well as forecasted precipitation and temperature data. The precipitation ranking, temperature ranking, cumulative biomass ranking, transpiration ranking, estimated yield trends, and drought index indicated satisfactory forecast results. The soil moisture forecast did not result in satisfactory forecast. The final step in the project was to create an example interface for agricultural producers and water managers to view drought related stresses. ArcGIS online was used to create maps which show graphs of the weekly drought index and soil moisture ranking. Maps were created at the county scale. These maps provide agricultural producers readily accessible information that can be used for decision making related to water management.

The Handbook of Irrigation System Selection for Semi-Arid Regions compares the various types of available irrigation systems for different regions and conditions, and explains how to analyze field data to determine the suitability of the land for surface, sprinkle, or drip irrigation systems. The book focuses on strategies for irrigation development and management and examines deficit irrigation and partial root-zone drying systems. Also, solute leaching modeling under different irrigation systems, soil moisture conditions, and organic fertilizer application in arid areas are discussed. Further, it examines multi-criteria decision making for irrigation management and the appraisal of agricultural lands for irrigation in hot, sub-humid regions. Features: Presents comparative analysis to aid in the selection of the most appropriate types of irrigation systems according to land characteristics. Includes numerous practical case studies. Offers parametric evaluation systems for irrigation purposes. Considers data from semi-arid zones, each with different sub-climates. Focusing on semi-arid land, the book highlights parametric evaluation systems for irrigation purposes, along with the use of analytical hierarchy processes integrated with GIS to determine which systems are best suited. This comprehensive and well-illustrated handbook will be of great interest to students, professionals, and researchers involved with all aspects of irrigation in semi-arid regions.

Extreme weather and climate change aggravate the frequency and magnitude of disasters. Facing atypical and more severe events, existing early warning and response systems become inadequate both in scale and scope. Earth Observation (EO) provides today information at global, regional and even basin scales related to agrometeorological hazards. This book focuses on drought, flood, frost, landslides, and storms/cyclones and covers different applications of EO data used from prediction to mapping damages as well as recovery for each category. It explains the added value of EO technology in comparison with conventional techniques applied today through many case studies.

For some years, workers have been investigating the possibilities of integrating knowledge from soil and atmospheric sciences, crop physiology, and genetics in order to model crop response to water stress and breed plants for drought resistance.This book turns the theory into practice. Information, gathered from recent symposia and research journals, have been built upon by the authors. Up-to-date practices are cited, new practices devised, and approaches for scientific applications specified. The authors have devised numerous examples and applications for their approaches. Attention has been given to making these approaches credible in the light of economic and energy limitations. Because application of such practice over a wide area requires wide-areal sensing and measurement, recent advances in remote sensing for these purposes are outlined with methodology for practical application.The book will be of interest to a wide readership including crop managers and producers, soil scientists, agricultural micrometeorologists, plant breeders, water managers and stress physiologists.

The book contemplates different ways of approaching the study of vegetation as well as the type of indices to be used. However, all the works pursue the same objective: to know and interpret nature from different points of view, either through knowledge of nature in situ or the use of technology and mapping using satellite images. Chapters analyze the ecological parameters that affect vegetation, the species that make up plant communities, and the influence of humans on vegetation.
