In botany, drought tolerance is the ability by which a plant maintains its biomass production during arid or drought conditions. [ 1 ] [ 2 ] [ 3 ] Some plants are naturally adapted to dry conditions , surviving with protection mechanisms such as desiccation tolerance , detoxification , or repair of xylem embolism. [ 3 ]
The Texas and Southwest U.S. drought was also accompanied by a severe heat wave that brought record setting heat to much of Texas, including but not limited to bringing a 40-day stretch of temperatures at or above 100 °F (38 °C) to Dallas, Texas. Drought of severe magnitude also affected a large portion of the Southeastern US, especially ...
The 1950s Texas drought was a period between 1949 and 1957 in which the state received 30 to 50% less rain than normal, while temperatures rose above average. During this time, Texans experienced the second-, third-, and eighth-driest single years ever in the state – 1956, 1954, and 1951, respectively. [ 1 ]
Drought is a complex phenomenon − relating to the absence of water − which is difficult to monitor and define. [18] By the early 1980s, over 150 definitions of "drought" had already been published. [19] The range of definitions reflects differences in regions, needs, and disciplinary approaches.
Dryland farming caused a large dust storm in parts of Eastern Washington on October 4, 2009. Courtesy: NASA/GSFC, MODIS Rapid Response [1]. Dryland farming has evolved as a set of techniques and management practices to adapt to limited availability of water, as in the Western US and other regions affected by climate change for crops such as tomato and maize.
By definition, succulent plants are drought-resistant plants in which the leaves, stem, or roots have become more than usually fleshy by the development of water-storing tissue. [5] Other sources exclude roots as in the definition "a plant with thick, fleshy and swollen stems and/or leaves, adapted to dry environments". [ 6 ]
The drought is largely driven by temperature, which increases the rate of evaporation, with some contribution from the lack of precipitation. The several wet years since 2000 were not sufficient to end the drought. Researchers calculated that without climate change-induced evaporation, the precipitation in 2005 would have broken the drought.
The 2011 Texas drought dried up many of central Texas' waterways. This boat was left to sit in the middle of what is normally a branch of Lake Travis , part of the Colorado River . From October 2010 through September 2011, both major reporting stations in Austin, Camp Mabry and Bergstrom Int'l, had the least rainfall of a water year on record ...
