Agricultural production is directly affected by climate variables and climate change. These variables control crop growth and health, and annual crop yield over time. Increased crop yield is required to meet the needs of future population growth, but drought causes significant yield reductions for rain-fed and irrigated crops. Thus, studying the effect of climate change such as drought on crop production and cropping areas is essential to understand the potential change in crop yield and cropping system under warming climates in the state of Texas, nation and world as a whole.
CARC research scientists evaluated the impact of drought on crop yield and cropping area over 10 climate zones in Texas from 2008 to 2016 focusing on before and after the 2011 severe drought for four major crops grown in Texas. Results showed that drought had a greater impact on winter wheat (Triticum aestivum L.) and corn (Zea mays L.) and lesser impact on cotton (Gossypium spp.) and sorghum
This study provides valuable information that can be used to adopt appropriate measures to cope with future drought challenges in drought-prone regions.
