While a drought has put Caracas under widespread water rationing for the first time in years, for Venezuelans in this hillside slum it's just more of the same.

Every two weeks, Naisi Obando and her children join the crowd at the water truck when it rumbles up a dusty road into their shantytown. They bring barrels to be filled with a gushing stream from the truck, and use garden hoses to siphon the water from the barrels down steep stairs to their home.

"We really suffer a lot to get water here," Obando said.

Like many Latin American cities, poor sections around Venezuela's capital lack regular access to water because of unchecked sprawl and inadequate investment in infrastructure.

The situation has been made worse by a drought blamed on an El Nino weather phenomenon, which has left reservoirs at extremely low levels and this week prompted authorities to begin water rationing throughout Caracas.

The El Nino over the Pacific Ocean has been blamed for drier weather this year in parts of South America. In Bolivia, for instance, the United Nations said Friday it will provide food and water aid to families suffering from drought.

Ecuador has begun rolling blackouts to ration electricity because of low water levels in its hydroelectric dams. Water scarcity could also increase the already frequent power outages in Venezuela, where hydroelectric dams produce most of its electricity.

Some other Latin American countries are also facing unusually dry conditions.
