Traditional Food Storage Hacks That Work Without Fridge
These resourceful techniques not only minimize food spoilage but also highlight a deep respect for natural cycles. Here are seven tried-and-tested food storage hacks still in use today, offering a glimpse into the wisdom of off-grid living.
1. Zeer Pots: The Natural Clay Fridge
Popular in arid regions like Africa, the Middle East, and rural Rajasthan, Zeer pots—also known as pot-in-pot coolers—are ingenious clay refrigerators. A smaller clay pot is placed inside a larger one, and the gap between them is filled with wet sand. Covered with a damp cloth, this setup uses evaporative cooling to lower the temperature, keeping vegetables, milk, and cooked food fresh for a day or two.
2. Hanging Baskets Over Running Water
In hilly areas such as Himachal Pradesh and Uttarakhand, natural mountain streams are cleverly used to chill perishables. Food is stored in netted baskets or pots and suspended over flowing water. This method keeps items cool, aerated, and safe from animals and insects, thanks to the constant water movement and airflow.
3. Salting and Sun-Drying
Long before refrigeration, salt and sunlight were trusted preservers. In coastal Kerala, Tamil Nadu, Ladakh, and Northeast tribal regions, fish, meat, and vegetables are preserved by salting and drying under the sun. For example, salted mango slices can be sun-dried and stored for months, ready to spice up any dish later.
4. Cooling with Earthenware Pots
In states like Gujarat and Madhya Pradesh, clay pots or matkas are used to naturally cool items like water, buttermilk, and rice. These porous vessels allow evaporation, keeping contents cool without needing power. To boost cooling, pots are often wrapped in damp jute cloth and placed in shady corners. Airtight sealing is avoided to let the pots 'breathe.'
5. Underground Pit Storage
In colder regions like Kashmir and parts of Nepal, underground pits or cellars provide stable, cool environments ideal for storing root vegetables and grains. This natural insulation keeps potatoes, carrots, and millets fresh for months without refrigeration.
6. Natural Fermentation
The Himalayan regions are known for their expertise in fermentation. Foods like gundruk, sinki, and fermented radish are not only preserved without electricity but also become richer in flavour and nutrients. Fermentation also supports gut health, making it a wholesome storage technique.
7. Ash and Husk Preservation
In rural parts of Maharashtra and Odisha, ash and husk are used to extend the shelf life of root vegetables. Items like turmeric, ginger, garlic, and sweet potatoes are buried in a dry mix of these materials, stored in baskets or clay pots. This prevents moisture buildup and protects against insect infestations.
These age-old techniques continue to serve millions living off-grid, offering practical lessons in resilience, sustainability, and harmony with nature. In an era of increasing energy concerns and food waste, looking back might just be the way forward.

Intense Himachal rains topple Shimla tree, expose climate crisis risk
As intense monsoon rains hit Himachal Pradesh for the third consecutive year, scientists and environmentalists have raised serious concerns over the increasing frequency of high-intensity rainfall, triggered by a dangerous combination of global warming, delayed western disturbances, and monsoonal systems. The Shimla tree fall is another sign of the Himalayan region's rising climate risk. (Representative image)(ITBP/ ANI) The alarm was sounded following an incident early Thursday morning, when a massive deodar tree collapsed onto the Environment Directorate building in the US Club area of Shimla. The tree, which had been leaning precariously for days due to continuous rain, uprooted around 5:30 AM, causing partial damage to the building's roof and entrance gate. Fortunately, no casualties were reported. Senior scientist on climate Change at the State Science and Technology and Environment Directorate, Dr. Suresh Kumar Atri, speaking to ANI, said the disaster was a clear consequence of prolonged and intense rainfall and a stark sign of changing climate patterns. "This tree had been leaning dangerously for the last few days, especially after continuous rains," Atri said. "We had already written to the Municipal Corporation, alerting them. Today, at around 5:30 AM, the tree broke and fell. It caused significant damage to the building's metal roofing and gate, though luckily, there was no loss of life. Had this occurred during the day, it could have been disastrous." He said. Atri, a climate scientist, emphasised that such incidents are becoming more frequent due to global warming and disrupted weather systems. "The root cause of all this is global warming. It's leading to high-density rainfall events across not just Himachal, but the entire region," he explained. "If these global conditions persist, we will face even greater threats in the future." He said. He also clarified the commonly misunderstood term "cloudburst," that everywhere rainfall is not a cloudburst and it doesn't burst like a balloon. "There's no such thing as a cloud exploding, as people imagine. What actually happens is high-intensity rainfall in a very short span of time in a small geographical area. If 100 mm of rain falls within an hour over, say, 10-20 square kilometres, that qualifies as a cloudburst. For instance, in an area like Shimla, if 100 mm rain falls within an hour, it leads to flash floods a cloudburst-like situation. That's around 300 crore litres of water in a compact space, which overwhelms drainage systems and natural outlets." He said. Atri warned that this phenomenon is not isolated or region-specific. "These events don't only happen in remote areas. High-intensity rainfall can strike anywhere, anytime," he said. "In 2023, similar patterns led to devastating flash floods in Mandi district and even in parts of Uttarakhand, wiping out entire villages. The damage in Himachal alone crossed ₹10,000 crores last year." Said the scientist. He noted that this year, the state has already suffered over ₹3,000 crore in damages, and the monsoon season is still far from over. Dr. Atri further stressed the role of Arabian Sea warming and disturbed western disturbance patterns, which, when combined with the monsoon, result in extreme weather. "The Arabian Sea has warmed significantly, and this affects the western disturbances, which bring rain. When these disturbances interact with the monsoon, especially in a delayed fashion, the result is catastrophic, intense rainfall, landslides, and floods. This exact combination led to widespread destruction last year and is repeating again," he warned. Calling for urgent action, Attri advocated better watershed management and strict protection of natural drainage systems. "We must keep our water channels and watersheds clear. Water must flow out without obstruction. People should avoid going near rivers and streams during such weather conditions," he advised. The recent incident at the Environment Directorate building, while not fatal, serves as another reminder of the growing environmental vulnerabilities of Himalayan states. As monsoon patterns continue to evolve under the pressure of climate change, scientists are urging both the public and authorities to remain alert and to adapt proactively to this new climate reality.

How Arefa Tehsin brings India's wildlife to children in The Great Indian Safari
Arefa Tehsin believes every creature tells a story. And in her latest book, The Great Indian Safari (published by India Puffin), the Sri Lanka-based author takes one on a virtual safari across India. 'I wanted to take readers on a pan-Indian safari from Himalayan snowfields to coral reefs, termite hills to arid salt pans,' says Arefa, who adds that the book's idea came about when she realised there were 'few books that introduce younger children to India's incredible wildlife in an engaging, accessible way'. And so she does with her trusted friend 'Charred the bard' leading readers through the book's many chapters dedicated to the elephant, tiger, peacock, and more. Charred, a jungle crow, shares fun, engaging anecdotes about each of these creatures. Each chapter is peppered with vibrant illustrations, poems, tiny lessons on pronunciation, scientific names, how to act on a safari, and ends with a guide on where to spot the animal. 'I didn't just want the 'celebrities' of the wild like tigers and elephants (though they strutted in, of course), but also the quiet stars and the unsung heroes, be it the termite queens or the awesome asses,' says Arefa, 45, known for books like Amra and the Witch, and Iora & the Quest of Five. Addressing the importance of introducing biodiversity and conservation themes to children, Arefa says that when children realise they are not separate from Nature, but part of its unruly orchestra, they begin to care. 'Wonder leads to empathy, and empathy might just save our species. A tree isn't just a tree. It's a squirrel's skyscraper, a caterpillar's café, a crow's conference room. I believe that we are not saving Nature, Nature is saving us. So far, at least.' Given the extensive years of research that culminated into the book, were there any facts or lesser-known animals that surprised Arefa even today? 'Absolutely,' she says. 'Like how, 'Lakshadweep' means a hundred thousand islands (though it's only 36). Or how a termite queen can live up to 50 years while her soldier sons last barely 1–2. Or that Himalayan brown bear cubs are born while their mum is still asleep in hibernation. Nature is the original trickster. She doesn't play even by her own rules.' Arefa's most fascinating chapter, however, is the one on wild asses. 'These sleek, stubborn creatures graze on plants other animals turn their noses up at, and they're among the fastest animals in India. Who knew the desert had such horsepower?' she says. After The Great Indian Safari, Arefa is now working on her upcoming titles that include a sequel to Wild in the Backyard, The Big Little Birthday Party, Divine DNA, a highly illustrated book for teens about the animals in Indian mythology, and her second novel for adults, The Tale of a Magpie Robin. Priced at ₹327, Indian Safari is available online
