Economic effects of wild boar damage to crops in protected areas of Nepal

Abstract

Human wild-boar conflict is one of the prominent issues in Nepal, especially in areas adjacent to protected areas. Wild boars cause substantial damage to the agricultural crops and affect the lives of rural farmers through economic loss. However, the extent of this loss varies across protected areas. Thus, this study aims to compare the economic loss due to crop damage by wild boar between two protected areas with different management regimes; Shuklaphanta National Park (ShNP) and Dhorpatan Hunting Reserve (DHR). We used a questionnaire survey and descriptive statistics to characterize and compare the pattern of human wild boar conflicts between ShNP and DHR. Altogether, the two protected areas experienced a crop damage of 87,035.78 kg with an estimated economic loss of 26,389 USD within a year in our study. The most damaged crop in the ShNP was paddy whereas that in DHR was potato. We recorded a higher crop damage and economic loss in ShNP than in DHR. However, the severity of conflict is higher in DHR with around 8 % of the total production damaged by wild boar. Although the government declared wild boar an agricultural menace in 2023 and permitted killing on private lands, local communities should also apply other mitigation measures to prevent wild boars from entering crop fields. Additionally, the potential introduction of trophy hunting in ShNP (already permitted in DHR), following comprehensive studies, could help reduce economic losses associated with human-wild boar conflicts. Such combined efforts could create a more sustainable approach to managing wild boar populations while safeguarding local agriculture and livelihoods.
