From quite a few years now, farmers and fisherfolk worldwide are working the night shift as part of their adaptation to rising temperatures. Josana Pinto da Costa would take a tiny fishing boat out onto the waters that bordered Óbidos, Brazil, every morning. As the morning rose into the clear blue heavens above, she would float above the murky, whirling currents of the Amazon River Basin, her flat nets pulling in writhing hauls.

That habit is now dangerous due to the intense heat in the Brazilian state of Pará. According to Pinto da Costa, speaking in Portuguese, this year’s heat has been really intense. She has shifted her working hours from day to night since it feels like the sun has gotten stronger.

The Shift to Nighttime Work

Farmers and fisherfolk worldwide are working the night shift as a practical solution to avoid the extreme heat of the day. Pinto da Costa no longer follows the routine that characterized the majority of her days but instead goes to the river in the dark to see if any fish are active before sunrise. Her life and her catch have suffered as a result. However, given the increasingly hazardous temperatures, it’s the only way she can carry on with her profession.

For agricultural workers who are facing increased temperatures due to climate change, switching from daytime to evening work is frequently proposed as the most practicable alternative. This change is already taking place in many of the communities that catch, raise, and harvest the world’s food supply, from Brazil to India to the United States, so it is no longer just a suggestion. According to studies, starting work when it’s still dark outside or even switching to an all-nocturnal schedule is the most popular way for most crop-growing regions to adjust to rising temperatures.

Impacts on Communities

For Pinto da Costa and her Brazilian fishing village, this has been the case. In a community already feeling the effects of climate change, working at night has been an added strain. Farmers and fisherfolk worldwide are working the night shift to sustain their livelihoods under similar conditions. Decades of extreme drought conditions have existed in the area, physically separating people as streams dried up and leading to the death of fish.

Regularly working at night can cause physical and emotional disruptions as well as long-term health issues, according to research. Additionally, fishing at night is endangering fishermen’s social and communal habits. Sleeping throughout the day might restrict the amount of time spent with loved ones and reduce the times at which goods can be exchanged or sold in local marketplaces.

Additionally, it is affecting their capacity to sustain themselves and their families via a trade that has been practiced for centuries. Pinto da Costa explained that working at night had reduced their productivity and resulted in their finding fewer fish. She added that they had been working more hours with less food and production, emphasizing that this was happening across all regions of Brazil.

The social and economic effects of switching to nocturnal hours are especially dangerous for women. Even though they make up about 45% of Brazil’s artisanal fishermen, women are paid less than men. This implies that their margins are much worse when harvests fall as a result of evening fishing.

Tens of thousands of women fishermen gather shellfish in the Brazilian state of Bahia, while in Maranhão, women fishermen use tiny nets to herd shrimp to the coast. In the northeastern region of Brazil, women also handle the majority of clam picking. Women were able to manage cultural or gendered family obligations, such as running the home and caring for the kids, because these jobs were often daytime and located near their homes. Zia Mehrabi, a researcher specializing in food security and climate at the University of Colorado, explained that moving to the evening to escape intense heat posed a fundamental challenge, particularly because changing working hours disrupt families.

India

Pastoralist tribes like Bhavana Rabari face similar difficulties in Gujarat, India. Traditional rituals are becoming harder to maintain due to rapidly rising temperatures. In addition to their animals grazing less and generating less milk, pastoralists are finding it harder and harder to locate pastureland.

Rabari has heard of other farm laborers attempting to work overnight. However, she stresses that it is not safe or feasible to care for herds in the dark. Instead, to avoid the heat, her family gets up at five in the morning and works on projects while it is cooler.

United States

In order to avoid the worst heat, fourth-generation farmer April Hemmes in Iowa, USA, has adjusted by beginning her job earlier in the day. She agrees with Rabari that working at night is impossible because of the dangers and inefficiencies involved. In order to control her workload and lessen her exposure to hazardous heat conditions, Hemmes has made investments in technology such as autonomous tractors.

Expert Perspectives and Future Challenges

During times of excessive heat, outdoor workers suffer some of the most dangerous health hazards because of their regular noon hours and limited access to shade. Farmers and fisherfolk worldwide are working the night shift as a coping mechanism for these hazardous conditions. According to recent research by Zia Mehrabi and Naia Ormaza Zulueta, if emissions are not reduced, dangerous working hours will rise by 8% worldwide by 2050.

Mehrabi highlighted that the number of days people would experience violations of their rights to a safe climate would substantially increase, along with a reduction in the number of possible working hours in a season and productivity.

With 94 percent of the population potentially facing more than 100 dangerous workdays per year by 2050, India is predicted to confront the most obstacles. Rising heat hazards will also affect farmers, pastoralists, and fishermen in Brazil and the United States.

Final Thoughts

The workforce throughout the world is finding it difficult to adjust to the rising temperatures. Farmers and fisherfolk worldwide are working the night shift to cope with these challenges, but this transition is by no means a simple fix for communities such as Hemmes’, Rabari’s, and Pinto da Costa’s. It upends established social and cultural norms and poses new threats.

In order to address the effects of climate change on workers throughout the world, policymakers and academics must give priority to inclusive, community-driven solutions.
