By Lisandra Paraguassu MUCUM, Brazil (Reuters) -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.

State of play: In the floods in Brazil's Rio Grande do Sul state, 147 people have died in the past two weeks, more than 120 are missing and around 620,000 have been displaced from their homes — with about 155,000 of those homes completely lost.
