“Now we live well,” say both Givaldo and Nina dos Santos, after showing visiting farmers their 1.25-hectare farm in Brazil’s semi-arid Northeast, which is small but has a great variety of fruit trees, thanks to innovative water and production techniques.

Givaldo began his adult life in Rio de Janeiro, in the southeast, where he did his military service, married and had three children. Then he returned to his homeland, where it was not easy for him to restart his life on a farm in the municipality of Esperança, in the northeastern state of Paraiba, with his new wife, Maria das Graças, whom everyone knows as Nina and with whom he has a 15-year-old daughter.

“I’d leave at four in the morning to fetch water. I would walk 40 minutes with two cans on my shoulders, going up and down hills,” recalled the 48-year-old farmer.

But in 2000, thanks to a rainwater collection tank, he finally managed to get potable water on Caldeirão, his farm, part of which he inherited.
