Devastating and ongoing flooding in southern Brazil is forcing some of the half million displaced residents to consider uprooting their lives from inundated towns to rebuild on higher ground.
Two weeks after the onset of torrential rains, the Guaiba River running by state capital Porto Alegre is rising again, having surpassed its all-time high. In the state of Rio Grande do Sul, the streets of dozens of towns have turned into slow-moving rivers.

Just in the area around Porto Alegre, where four rivers converge to form the Guaiba River, researchers estimate that nearly 3,800 square kilometers were flooded. That is more than the urban footprint of the Washington D.C. metro area, which includes 10 counties in two adjacent states.
With hundreds of thousands of families fleeing the floods, the disaster – which has killed at least 147 people, with 127 still missing – could touch off one of Brazil's biggest cases of climate migration in recent history.

Southern Brazil's location at the confluence of tropical and polar currents has fed periods of increasingly intense drought and rains due to climate change, according to scientists.
The record devastation in Rio Grande do Sul follows floods in the second half of last year, leading many of the 538,000 people now displaced from their homes to consider more extreme adaptations.
For the third time in seven months, businessman Cassiano Baldasso had to remove wheelbarrows of mud from his home in Muçum, a small town 150 kilometers upriver from Porto Alegre, only to see the waters rise again. He says he has had enough.

"I have no idea where I'm going, but it will be somewhere far from the river, where our lives will not be at risk," Baldasso told the reporter as he removed another cart of mud from inside the house.
Mayor Mateus Trojan said many of Muçum's 5,000 residents will have to relocate. His office is planning to rebuild 40 percent of the town elsewhere.
Baldasso had already saved his family in September by climbing onto the roof of their two-story house until they were rescued by the fire brigade in the middle of the night.

During that flood, just a few blocks away, Maria Marlene Venancio's house was swept away, and she lost everything. This month, the rented house she had moved to was flooded 1.5 meters deep. She fears it is time to leave Muçum.
"I think the town will become a river one day, and it will be difficult for us to live here. People with money are all leaving," she said.
Governor Eduardo Leite has said initial calculations show Rio Grande do Sul will need at least 19 billion reais ($3.7 billion) to rebuild from the disaster. The federal government has offered to freeze 11 billion reais of debt payments for three years.
Environmental experts warn that there is no alternative for some towns in the state but to relocate entire neighborhoods.
"We need to move urban infrastructure away from high-risk environments and return space to the rivers ... so they no longer impact cities with such magnitude," said ecologist Marcelo Dutra, a professor at Rio Grande Federal University.
"We can't oppose nature. We have to wake up to this force that is telling us we need to adapt and respect nature," he said.
