High in the hills of northwestern Tunisia, farmers are tending thousands of fig trees with a unique system of terracing they hope will protect them from ever-harsher droughts.

But the "hanging gardens" of Djebba El Olia have been put to the test this year as the North African country sweltered through its hottest July since the 1950s.

That has exacerbated a long drought that has left Tunisia's reservoirs at just a third of their capacity.

The gardens are supplied with water from two springs high in the mountains.

The water is fed into the orchards by a network of canals that are opened and shut at set times, according to the size of the orchard.

Crucially, a wide variety of crops provides resilience and in-built pest control, unlike the monocultures that dominate modern agriculture and require huge inputs of pesticides to survive.

"We grow figs but also other trees like quinces, olives and pomegranates, and beneath them we plant a wide range of greens and legumes," said activist Farida Djebbi as insects buzzed between thyme, mint and rosemary flowers.

Djebbi pointed out some of the channels, which irrigate the area's 300 hectares (740 acres) of steeply sloping orchards.

In 2020, the Food and Agriculture Organization recognized the system as an example of "innovative and resilient agroforestry", adding it to an elite list of just 67 "Globally Important Agricultural Heritage Systems".

The system "has been able to adapt and take advantage of an inhospitable topography", the UN agency said.

"Through the use of natural geological formations and the use of stones, local communities have been able to transform the landscape into fertile and productive lands."

The FAO praised the diversity of local crop varieties grown by the area's farmers, as well as their use of wild plants to repel potential pests and of livestock to "plough" and fertilize the soil.

- Growing up with figs -

While nobody knows exactly how old the system is, human habitation in the area predates the Carthaginian civilization founded in the ninth century BC.

But while it may have endured for generations, the system is under threat as climate change kicks in.

Activist Tawfiq El Rajehi, 60, says the flow of water from springs irrigating the area has dropped off noticeably, particularly in the past two years.

Unlike in previous years, the surrounding peaks no longer get covered in snow each winter, and the leaves of many of the trees in the lower part of Djebba are yellowing and sick.

Rajehi, a teacher at the local school, said climate change and low rainfall were compounded by another factor: farmers favoring cash crops.

"Some farmers have moved to growing more figs instead of less water-intensive crops because figs have become more profitable in recent years," he said.

"We need to keep a good balance and variety of plants."

Nevertheless, residents say they are proud of their heritage.

Farmer Lotfi El Zarmani, 52, said there was also growing demand for Djebba figs, which were given a protected designation of origin by the agriculture ministry in 2012 -- still the only Tunisian fruit to enjoy the certification.

"They're getting a reputation, plus exporting them has become easier, plus they bring higher prices," Zarmani said.

Rajehi's daughter, university student Chaima, put on protective gloves as she set out to harvest the fruit from her family's small lot.

"Figs are more than a fruit for us. We're born here among the fig trees and we grow up with them, we learn from a young age how to look after them," the 20-year-old said.

Djebbi is working to persuade farmers to preserve traditional ways of processing the products harvested in the area.

She is working with 10 other women on a cooperative that distils essence from wildflowers, dries figs, and produces fig and mulberry jam.

"Products we learnt how to make from our mothers and grandmothers are becoming popular because they're of such high quality," she said.

What the Shell: Scientists Marvel as NZ Snail Lays Egg from Neck

A rare New Zealand snail has been filmed for the first time squeezing an egg from its neck, delighting scientists trying to save the critically endangered meat-eating mollusk.

Threatened by coal mining in New Zealand's South Island, a small population of the Mount Augustus snail was transplanted from its forest habitat almost 20 years ago to live in chilled containers tended by humans.

Little is known about the reproduction of the shellbound critters, which can grow so large that New Zealand's conservation department calls them "giants of the snail world".

A conservation ranger said she was gobsmacked to witness a captive snail laying an egg from its neck -- a reproductive act well documented in other land snails but never filmed for this species.

"It's remarkable that in all the time we've spent caring for the snails, this is the first time we've seen one lay an egg," conservation ranger Lisa Flanagan said this week.

"We caught the action when we were weighing the snail. We turned it over to be weighed and saw the egg just starting to emerge from the snail."

Conservation department scientist Kath Walker said hard shells made it difficult to mate -- so some snails instead evolved a special "genital pore" under their head.

The Mount Augustus snail "only needs to peek out of its shell to do the business," she said.

The long-lived snails can grow to the size of a golf ball and their eggs can take more than a year to hatch.

They eat earthworms, according to New Zealand's conservation department, which they slurp up "like we eat spaghetti".

Conservation efforts suffered a drastic setback in 2011, when a faulty temperature gauge froze 800 Mount Augustus snails to death inside their climate-controlled containers.

Fewer than 2,000 snails currently live in captivity, while small populations have been re-established in the New Zealand wild.
