"Wild pigs (Sus scrofa) population management in Brazil: mitigating crop damages"
by Gianetti, Giovani William, Carla Grasiele Zanin Hegel and Joaquim Bento Ferreira-Filho

This paper evaluates wild pig management in Brazil by systematically assessing the avoided crop damage impacts of controlling the wild pig population and their repercussions on both economic and environmental aspects. We employed the Computable General Equilibrium model TERM-BR15 to conduct simulations from 2023 to 2030. We developed three scenarios, varying in the intensity of wild pig damage, ranging from minimum to maximum. Within these scenarios, we introduced shocks of increasing corn, soybeans, and sugarcane outputs by adjusting the pig harvest rate (HR) from 25% to 50% and modifying crop consumption (CC) based on the animals' body weight, ranging from 3% to 5%. The intermediate scenario shows a 0.15% increase in Gross Domestic Product and a 0.17% rise in real household consumption compared to the 2030 baseline, attributed to wild pig population management measures. These figures represent increments of US$ 203.18 and US$ 151.49 per wild pig managed, respectively (based on a BRL to US$ exchange rate of 5). National output for corn, soybeans, and sugarcane would increase by 11.10%, 6.33%, and 0.08%, respectively, alongside a reduction in greenhouse gas (GHG) emissions intensity and a reduction in deforestation. Regionally, real GDP would increase in all Brazilian regions. However, areas unaffected by wild pigs would experience a decrease in grain production due to declining prices resulting from increased output in other regions. Our results offer an evidence-based estimation of wild pig crop damages and their impact on the Brazilian economy and environment. This information can assist decision-makers in actively shaping public policies for wild pig population management.
