As global temperatures rise, livestock producers in tropical and sub-tropical regions face intensifying heat stress challenges, requiring adaptation strategies that protect animal welfare while maintaining food security.
Heat adaptation for tropical livestock is both a productivity concern and a welfare imperative. Animals experiencing heat stress suffer measurably: increased respiratory rate, reduced feed intake, lethargy, and in severe cases hyperthermia and death. Climate-smart livestock management integrates shade provision, water access, modified feeding schedules, breed selection, and housing design to reduce heat load. In smallholder systems where resources are limited, low-cost interventions such as shade trees and wallows deliver significant welfare benefits. Welfare organisations and development agencies increasingly work together on heat adaptation as a shared priority.
