Calabria, ItalyEach year in mid-September the tiny, coastal Italian town of Diamante undergoes a transformation. Around 200,000 people come during the period of five days to celebrate the famous Calabrian chili pepperknown because of its harsh sting somewhere within jalapeo and cayenneagainst the setting of impressive murals of fishermen, religious figures, and abstract art.

Bundles of dried crimson Diavolicchio, the regions most typical chili variety, dangle from balconies. Enormous scarlet chili sculptures stand erect in the towns squares. Crowds stroll across the seaside, wearing red clothing, chili-shaped earrings, and makeshift crowns.

Thefestival is celebrating its 30th year, however in many ways it has been per year unlike any. Italy faced raging, climate change-caused heat waves and scant rains, causing its worst drought in over 70 years. Italian agriculture, especially in the northern regions, has suffered immensely because of this, with crop yields, including rice, wheat, corn, olives, and tomatoes, plummeting byaround 70 percent.

Chili pepper crops, which arent as thirsty as others, fared better but haven’t escaped heat unscathed. In Calabria, alongside Sicily the biggest pepper-producing area in Italy, The drop in yields this season has been about 20 to 30 percent, says Maria Viggiano, co-owner of Valle Lao Agriculture Company, among the regions largest chili pepper farms. That decline, however, wasnt due to drought, since Calabria had enough moisture but from the relentless heat; temperatures spiked up to 100 degrees Fahrenheit on the summer, about 15 degrees greater than average. Still, chili peppers resilience and versatility have helped to reduce economic losses, Viggiano says.

For most, this years festival is really a celebration of that: the plants heroic survival when confronted with rapidly increasing temperatures made more intense and frequent by climate change.

Chili history

Chili peppers at the festival are everywhere in myriad sizes and shapes: small and button-shaped, long and slender, half-bent like crooked fingers. They’re infused in oils and grappa, melded into goat’s cheeses, powdered to dust, coupled with sardines, and used to create traditional recipes, like the much-loved Nduja, a spicy, spreadable chili pork sausage. In addition they come in chili-themed film screenings and Red Hot Chili Pepper cover bands. The primary event, however, is really a race to see who is able to eat probably the most chilis in 30 minutes. This season, two contestants broke even at 1.5 pounds each.

The complete town comes alive, says Enzo Monaco, founder of the festival and president of the Italian Academy of Chili Peppers.

When Monaco and his friends first launched the chili pepper festival in Diamante, in 1992, the focus wasnt so much on the pepper itself. It had been on its well-known aphrodisiac effects.We built a phallus that has been around three meters (10 feet) tall, says Monaco.

Because the festival gained momentum and began to attract more tourists from around Italy, however, Monaco started making enemies. The priests, the church, they started pushing back, so we’d to tone things down, he says.

That tension between chili peppers and the church isn’t new. Over 500 years back, when Christopher Columbus brought chili peppers back from his travels in the Americas, he was hoping to market the spice in Spain and across Europe. But his plan didnt quite work, says Monaco, who wrote a book on this issue. Rich and noble classes didnt just like the taste, and the church saw its reputation being an aphrodisiac as anathema to its sacred valuesso much in order that they convinced monks in Mexico to define it as a spice that awakens deranged suggestions. The church in Italy also pushed back contrary to the spread of chili peppers in the united kingdom when it arrived there around 70 years later.

It had been only once chili peppers reached poorer classes that the spice really began to be appreciated. Lots of people in southern parts of Italy, including Calabria, didn’t eat meat and were limited by vegetables like eggplants, peppers, and tomatoes. Chilis provided an ideal condiment to provide these vegetables a kick of flavor, says Monaco.

After that, chilis quickly spread round the country and around the world, assisted by migrating birds, whose insufficient taste receptors leave them unfazed by chilis spice. Birds would eat chilis, do their business in the air, the seed would fall below, and chilis would spread this way, Monaco says.

The truth that chili peppers are very easy to cultivate also played a significant role in its spread. Whatever you needed was soil, a vase, a seed, and stick it on a balcony beneath the sun and youd get chili peppers year-round, he says. Calabriawith its sunny weatherwas a perfect spot for the plant to thrive and contains end up being the region of Italy that eats probably the most chili peppers.

Chilis savior

As a crop, chilis are incredibly versatile: They could be harvested and sold fresh, but may also be dried, fermented, or pickled. When producing dried chilis, long and intense heat can in fact speed up the procedure, says Viggiano. Some farmers purchased this with their advantage. If we cant sell it [fresh], we dry them up and sell them. Its another method of facing this issue, says Francesco Donato, a chili pepper farmer from Diamante.

There exists a limit to the chili plants toughness, though. If temperatures stay high for too much time, plants will most likely wilt, discolor, and finally die, even though they will have enough water, says Viggiano, who saw that happen in her very own fields.

Farmers emphasize that its heat waves, instead of droughts, that pose an instantaneous threat to chili peppers in your community. Diamante is surrounded by mountains, small rivers, and plentiful aquifers that, for the present time, provide sufficient water because of its agriculture, says Viggiano. Heat waves, however, will probably strike each year, sufficient reason for increasing intensity because the ramifications of climate change tighten their grip on global weather.

Monaco, however, is more optimistic. With a large number of types of chili peppers on earth, and the crops versatility and robustness, he could be convinced that chili peppers will endure and adapt. And when chili peppers cant handle the intense heats close to the coast of Calabria, farmers can plant higher up in the encompassing mountains where temperatures are milder, says Monaco.

For me the chili pepper wont have way too many difficulties, he says. Chili peppers can grow in all sorts of altitudesfrom sea to mountains.
