ESPERANÇA/CUMARU, Brazil, Jul 12 2018 (IPS) - “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.

And in 2011 he got water for production, through a “barreiro” or pond dug into the ground. Two years later, a “calçadão” tank was built on a terrace with a slope to channel rainwater, with the capacity to hold 52,000 litres.

“Now we have plenty of water, despite the drought in the last six years,” said 47-year-old Nina. The “barreiro” only dried up once, two years ago, and for a short time, she said.

The water allowed the couple to expand their fruit orchard with orange, grapefruit, mango, acerola (Malpighia emarginata) and hog plum (Spondias mombin L, typical of the northern and northeastern regions of Brazil) trees.

With funding from a government programme to support family farming and from the non-governmental organisation Assessment and Services for Alternative Agricultural Projects (ASPTA), focused on agroecology, the couple purchased a machine to produce fruit pulp and a freezer to store it.

“When the pulp sale takes off, our income will grow,” said Givaldo. “For now we earn more with orange and lemon seedlings, which sell better because they last longer than other fruits.”

Besides storing water in the “barreiro”, they also raise tilapia (Oreochromis niloticus), a species of fish, for their own consumption. Meanwhile, in the garden, in addition to fruit trees, they grow vegetables, whose production will increase thanks to a small greenhouse that they have just built, where they will plant tomatoes, cilantro and other vegetables for sale, Nina said with enthusiasm.

The productive activities on their small farm are further diversified by an ecological oven, which they use to make cakes and which cuts down on the use of cooking gas while at the same time using very little wood; by the production of fertilizer using manure from calves they raise and sell when they reach the right weight; and by the storage of native seeds.

The boundaries of their farm are marked by fences made of gliricidias (Gliricidia sepium), a tree native to Mexico and Central America, which offers good animal feed. The Dos Santos family hopes that they will serve as a barrier to the agrochemicals used on the corn crops on neighbouring farms.

Some time ago, the couple stopped raising chickens, which were sold at a good price due to their natural diet. “We had 200, but we sold them all, because there are a lot of robberies here. You can lose your life for a chicken,” Givaldo said.

Organic production, diversified and integrated with the efficient utilisation of water, turned this small farm into a showcase for ASPTA, an example of how to coexist with the semi-arid climate in Brazil’s Northeast.

This is why they frequently receive visitors. “Once we were visited by 52 people,” said the husband.

In the last week of June, the couple received 20 visitors from El Salvador, Guatemala and Honduras, mostly farmers, in an exchange promoted by the United Nations Food and Agriculture Organisation (FAO) and Brazil’s Articulation of the Semi-Arid (ASA), a network of 3,000 social organisations, including ASPTA.

Another farm visited during the exchange, accompanied by IPS, was that of Joelma and Roberto Pereira, in the municipality of Cumaru, in the state of Pernambuco, also in the Northeast. They even built a roof over the sloping terrace that collects rainwater on their property, to hold meetings there.

Three tanks for drinking water and one for production, a biodigester that generates much more gas than the family consumes, a system for producing liquid biofertiliser, another for composting, a small seedbed, cactus (Nopalea cochinilifera) and other forage plants are squeezed onto just half a hectare.

“We bought this half hectare in 2002 from a guy who raised cattle and left the soil trampled and only two trees. Now everything looks green,” said Joelma, who has three children in their twenties and lives surrounded by relatives, including her father, 65, who was born and still lives in the community, Pedra Branca, part of Cumaru.

The couple later acquired two other farms, of two and four hectares in size, just a few hundred metres away, where they raise cows, sheep, goats and pigs. The production of cheese, butter and other dairy products are, along with honey, their main income-earners.

On the original farm they have an agro-ecological laboratory, where they also have chicken coops and a bathroom with a dry toilet, built on rocks, in order to use human faeces as fertiliser and to “save water”.

“We reuse 60 percent of the water we use in the kitchen and bathroom, which passes through the bio water (filtration system) before it is used for irrigation,” Joelma said, while reciting her almost endless list of sustainable farm practices.

It all began many years ago, when her husband became a builder of rainwater collection tanks and she learned about the technologies promoted by the non-governmental Sabiá Agro-ecological Development Centre in the neighbouring municipality of Bom Jardim. Sabiá is the name of a bird and a tree that symbolise biodiversity.

Some tobacco seedlings stand out in a seedbed. “They serve as a natural insecticide, along with other plants with a strong odor,” she said.
