Rice farmers in the Argentine province of Entre Rios often look like mechanics. "They're always full of grease, because they haul diesel fuel around all the time, for their water pumps," says local farmer Arturo Deymonnaz. He, however, doesn't have that problem, because he uses solar energy to grow his rice.
"The idea came to a group of schoolmates and me in 2014, but we never thought it could become a reality," says Sebastián Ieraci, 23, as he points to a multitude of photovoltaic solar panels shining on the roof of the Antonio Devoto High School in the Argentine capital.
The intense white brightness of the salt flats interrupts the arid monotony of the Puna in northwest Argentina, resembling postcards from the moon. Beneath its surface are concealed the world's largest reserves of lithium, the key mineral in the transition to clean energy, the mining of which has triggered controversy.
In Argentina's Puna region, at 4,000 metres above sea level, the color green is rare in the arid landscape, which is dominated by different shades of brown and yellow. In this inhospitable environment, daily life has improved thanks to a system of piping water downhill from rock glaciers to local communities.
"On moonless nights it was very difficult to walk around this town," says Celia Vilte, a teacher from San Francisco, a highlands village of just 54 people in the extreme northwest of Argentina whose centre is not a town square but 40 solar panels, which provide one hundred percent of its electricity.
On the outer edges of Buenos Aires proper, where the paved streets end and the narrow alleyways of one of Argentina’s largest shantytowns begin, visitors can find the En Haccore soup kitchen.
"This is the best thing ever invented for the poor," says Emanuel del Monte, pointing to a tank covered in black tarps protruding from the roof of his house. It forms part of a system built mostly from waste materials, which heats water through solar energy and is improving lives in Argentina.
"Look at this water. Would you drink it?" asks José Pablo Zubieta, as he shows a glass he has just filled from a faucet, where yellow and brown sediment float, in his home in Villa La Cava, a shantytown on the outskirts of Argentina's capital.
Designed mostly by men, many digital applications are not suitable for women, but some initiatives are beginning to include them as programmers and beneficiaries in Latin America, where the gender gap is also technological.
Climate change poses a global threat to food production, but for agriculture in Argentina it could also present new opportunities. In some areas of the country, farming conditions will improve, according to an analysis by experts of the latest climate projections.
Solar panels shine on the rooftop terraces of 10 neat buildings with perfectly straight lines and of uniform height, an image of modernity that contrasts with the precariously-built dwellings with unplastered concrete block walls just a few metres away, with rooms added in a disorderly manner, surrounded by a tangle of electric cables.
"Our philosophy is based on two principles: zero tolerance of pesticides or bosses," says Leandro Ladrú, while he puts tomatoes and carrots in the ecological bag held by a customer, in a large market in the Argentine capital, located between warehouses and rusty old railroad cars.
Nancy López lives in a house made of clay, wood and corrugated metal sheets, on private land dedicated to agriculture. She is part of an indigenous community of 12 families in northern Argentina that, like almost all such communities, has no title to the land it occupies and lives under the constant threat of eviction.
"In 2001 I was raped. I was 31 years old, had two university degrees and was still doing postgraduate studies, I had family, friends, a job. Many more resources than most rape victims have. Even so, it was the start of an ordeal whose scars I still feel today."
Left blind by a beating from her ex-husband, Susana Gómez barely managed to avoid joining the list of nearly 2,800 femicides committed annually in Latin America, but her case shows why public policies and laws are far from curtailing gender-based violence in the region.
The seed was planted more than 20 years ago by a group of indigenous women who began to gather to try to recover memories from their people. Today, women are also the main protagonists of La Voz Indígena (The Indigenous Voice), a unique radio station in northern Argentina that broadcasts every day in seven languages.
"I've been used to hauling water since I was eight years old. Today, at 63, I still do it," says Antolín Soraire, a tall peasant farmer with a face ravaged by the sun who lives in Los Blancos, a town of a few dozen houses and wide dirt roads in the province of Salta, in northern Argentina.
"We are the people who are excluded from the system," says Rafael Rivero, sitting in his apartment in a new social housing complex next to one of the largest slums in Buenos Aires. The contrast sums up the complexity of the social reality in the Argentine capital.
In front of one of the busiest railway stations in the capital of Argentina, there are long lines to buy vegetables, which farmers themselves offer directly to consumers, at prices several times lower than those seen in stores.
Questioned for its environmental and health impacts in Chile, where it is one of the country's main economic activities, salmon farming is preparing to expand in Argentina from Norway, the world's largest farmed salmon producer.
The news has triggered a strong reaction from civil society organisations.
The Argentine Senate's rejection of a bill to legalise abortion did not stop a Latin American movement, which is on the streets and is expanding in an increasingly coordinated manner among women's organisations in the region with the most restrictive laws and policies against pregnant women's right to choose.
