LA PAZ, Bolivia (AP) - Flooding from torrential rains in recent weeks has destroyed crops, killed thousands of cattle and left hundreds of people homeless, the Civil Defense Office said Monday. The rains ended a severe drought that affected a third of Bolivia earlier this month. Rain-swollen rivers overflowed their banks, covering fields of soy bean, cotton, corn and grapes. The rains have also flooded parts of the cities of Santa Cruz, with a population one million, and Cochabamba, with a population of 450,000. The Civil Defense Office said the crops of 22,000 families had been destroyed and at least 10,000 cattle killed, as well as hundreds of people left homeless. The affected families have not only lost their crops but are also facing severe food and potable water shortages, the office said.
