That makes it a good place to observe the phenomenon I research: complex social problems. In academia, this concept refers to problems like corruption, crime and traffic – problems that, in practice, cannot be solved. They must simply be mitigated or managed.
São Paulo is a dense city, with scarce green space and little to no animal life – no squirrels, no raccoons, not even a lot of birds. So I was astonished when, in January, I learned that scorpions had infested my neighborhood.
It turns out, people across the city and São Paulo state were having the same problem with these dangerous, venomous bugs. Statewide, scorpion stings have increased threefold over the last two decades.
Four kinds of scorpion live across Brazil, but historically only in rural areas. São Paulo residents are urbanites. We have conquered nature – or so we thought.
Brazil’s urban scorpions
Brazil’s scorpion infestation is the perfect example of how unpredictable modern life has become. It is a hallmark of what those of us in the complex problems field call a “VUCA” world – a world that’s volatile, uncertain, complex and ambiguous.
Some 2.5 billion people worldwide, from Mexico to Russia, live with scorpions, which generally prefer hot and dry habitats.
But Brazil’s cities also provide an excellent habitat for scorpions, experts say. They offer shelter in sewage networks, plenty of water and food in the garbage that goes uncollected, and no natural predators.
Scorpions, like the cockroaches they feast on, are an incredibly adaptable species. As the weather in Brazil gets hotter due to climate change, scorpions are spreading across the country – including into its colder southern states that rarely, if ever, had reports of scorpions prior to this millennium.
The number of people stung by scorpions across Brazil has risen from 12,000 in 2000 to 140,000 last year, according to the health ministry.
Most scorpion stings are extremely painful but not fatal. For children, however, they are dangerous and require urgent medical attention. Eighty-eight people died from their wounds in 2017, Brazil’s O Globo newspaper reports, highlighting the lack of adequate medicare care available in small towns. Many of the dead are children.
In Americana, a city with about 200,000 inhabitants in São Paulo state, teams that perform night searches for scorpions captured more than 13,000 last year – that’s the equivalent of one scorpion for every 15 people.
Worse yet, the species terrorizing Brazilians is the highly poisonous yellow scorpion, or tityus serrulatus. It reproduces through the miracle of parthenogenesis, meaning a female scorpion simply generates copies of herself twice a year – no male participation required.
