; 5.2 Politics Beginning in 1949 Texas was hit with a devastating drought that extended until 1957 Rainfall decreased 30 to 50 percent while temperatures rose killing crops livestock and triggering a rise of dust storms As a result the number of Texas farms and ranches declined by nearly 100,000 and Texas experienced a period of mass urbanization as the rural population moved to the city to rebuild their livelihoods the state's rural population declined from more than a third of the population to a quarter. As a result the Texas Water Development Board was created in 1957 and the state began a period of building a diverse system of water conservation plans This included increasing access to groundwater and creating lakes by damming rivers, Spanish possessions in Asia and Oceania In December southward-moving cold fronts can bring cold rain low wind chills and rarely frozen precipitation Early January is the coldest time of the year with temperatures moderating slightly by February Winter is also the driest part of the year for Houston. . !
