This story is a part of Nature’s 10, an annual listing compiled by Nature’s editors exploring key developments in science and the people who contributed to them.

In a yr that introduced unrelenting dangerous environmental information, with file world warming, searing heatwaves and fires, Marina Silva delivered a hopeful message on 3 August. Brazil’s surroundings and climate-change minister introduced that there had been a 43% drop in deforestation alerts on the idea of satellite tv for pc photos of the Amazon rainforest between January and July 2023, in contrast with the identical interval in 2022. This was a pointy shift from the earlier 4 years, which had seen a marked rise in such alerts.

The turnaround for environmental protections in Brazil began on 1 January, when Luiz Inácio Lula da Silva took workplace as president and Marina Silva assumed her present function. It’s her second time heading the ministry of the surroundings and local weather change, which she ran beforehand between 2003 and 2008, throughout Lula da Silva’s first and second presidencies.

Throughout her first time in workplace, Marina Silva tackled rampant forest-clearing actions by main the event of the Motion Plan for the Prevention and Management of Deforestation within the Authorized Amazon (PPCDAm) — a programme that achieved an 83% lower in deforestation between 2004 and 2012 within the Brazilian Amazon.

However most of the protections she helped to place in place had been dismantled by the federal government of Jair Bolsonaro, Brazil’s president from 2019 to 2022. Throughout his time period, the federal government issued 40% fewer fines for environmental crimes, and logging within the Amazon elevated by about 60% in contrast with the 4 earlier years.

Silva and her group began this yr, she says, “with the robust mission to reconstruct what had been dismantled and, on the identical time, create new outcomes for environmental coverage”.

From an early age, Silva has embraced tough challenges. She was born in 1958 in Rio Branco, Brazil, within the coronary heart of the Amazon area. Coming from a poor household of 11 kids (3 of whom died younger), Silva began work at an early age alongside together with her siblings, extracting latex from rubber bushes. She wished to be a nun and didn’t be taught to learn or write till she was an adolescent.

Silva met environmental activist Chico Mendes (who was killed in 1988 by a rancher) on a course in rural management within the mid-Seventies and began her profession in environmental activism, which led finally to politics. In 1994, she grew to become Brazil’s youngest elected senator at 35 years outdated.

In her present function, Silva isn’t all the time in alignment with the present authorities, says Pedro Jacobi, an environmental-governance researcher on the College of São Paulo, Brazil. The Lula da Silva authorities intends to extend drilling for oil and fuel — together with on the mouth of the Amazon River, says Jacobi. So the surroundings ministry is “strolling on skinny ice on a regular basis”, he says.

However by way of controlling and stopping deforestation, Brazil is doing its homework, says Natalie Unterstell, president of the Talanoa Institute, a climate-policy group based mostly in Rio de Janeiro, Brazil. “Marina Silva’s management on this agenda is essential and she or he is doing a rare job,” says Unterstell.

One key achievement was launching a revamped model, on 5 June, of the PPCDAm programme to guard the Amazon, which the Bolsonaro administration had shut down. Silva additionally reinstated assist for policing the area to implement environmental laws. And it was quickly clear that the insurance policies had been working. Between January and July, the Brazilian Institute of Setting and Renewable Pure Sources (IBAMA) issued 147% extra fines for environmental crimes than it had averaged throughout related months between 2019 and 2022.

In line with information from Brazil’s Nationwide Institute for House Analysis (INPE), deforestation within the Amazon from August 2022 to July 2023 is estimated to be 22% beneath what it was within the earlier 12 months. The speed is the bottom since 2018, however is about twice that of 2012, when deforestation was the bottom since INPE satellites started taking measurements in 1988.

Silva says one of many keys the explanation why environmental protections are working is {that a} broad swathe of the federal government is selling this agenda. “What fills me with pleasure,” she says, “is to see at work an idea that could be very expensive to me — that environmental coverage shouldn’t be restricted to just one sector, however traverse all ministries.”

However ending deforestation isn’t sufficient. “If international locations don’t cut back their CO2 emissions from fossil fuels, forests run the chance of being destroyed because of local weather change, in the identical manner. So we want a civilizational change, a change in our methods of life.”

She likens herself to a powerful fibre from an Amazonian tree, which is used to bind wooden to create rafts. “That is how I see my work,” she says, “bringing collectively those that can be found and no matter is critical to kind a assist floor within the difficult journeys of our time.”
