Dehorning of rhinos reduced poaching by 78% in Greater Kruger African reserves from 2017 to 2023

A new study found that dehorning rhinos proactively reduced poaching activity by 78% across 11 Greater Kruger African reserves from 2017 to 2023. In contrast, law enforcement interventions had no statistical effect on poaching. Dehorning removed the incentive for poachers and was cost-effective, with only a 1.2% of the budget spent.

“There could be irreversible, long-term damage”

A study published in Pediatric Pulmonology found that protracted bacterial bronchitis (PBB) in early childhood can lead to long-term pulmonary sequelae, including irreversible chronic lung damage. Children who did not receive antibiotics for at least two weeks were at higher risk of developing these consequences.
