Resource information
A questionnaire survey was conducted using 1,069 farmers about wild boar damage on agricultural land in the former Maebaru City in Fukuoka Prefecture. Abandoned cultivated land in the city was 11,202 ha. The questionnaire contained information about farming, damages attributable to wild boar, and the countermeasures against wild boar. The collection rate of valid questionnaires was 79.6%. The crop damaged the most was rice (53%), followed by vegetables (16%), oranges (13%), potatoes (5%), and others (13%). Statistical analysis of the relationship between land use and farmland damage showed a significant positive correlation between the presence of abandoned cultivated land and agricultural damage by wild boar. A geographic information system analysis revealed that 92.3% of the farmland damage existed within 100m from the forest, indicating that the distance from the forest influenced the damage. Moreover, 54.9% of the farmland damage existed within 100 m from the abandoned cultivated land, which suggested that the proximity of abandoned cultivated land had the possibility to affect agricultural damage. In addition, the effect of abandoned cultivated land on agricultural damage by wild boar was analyzed using regression analysis, and the result suggested that abandoned cultivated land be an important indicator for crop damage by wild boar.
