An inventory of birds and extent of damage to rice farms at the Kpong Irrigation Dam in the Lower Volta Basin, Ghana

Abstract

This study aimed to assess the incidence of birds raiding rice fields in the Kpong Irrigation Dam area of Ghana. Structured questionnaires were used to interview rice farmers in order to identify the bird species involved, quantify the economic losses incurred, and determine the mitigation measures employed by farmers. The main bird species identified as actively raiding rice fields were Ploceus cucullatus, Ploceus nigerrimus, Spermestes cucullatus, Spermestes bicolor, Quelea erythrops, and Dendrocygna viduata. The economic loss associated with bird raiding was estimated to range from 1,000.00 GHC (124.61 USD) to 1,500.00 GHC (186.92 USD), considering an exchange rate of 8.06 GHC to 1.00 USD at the time of the study. Additionally, farmers incurred 20.00 GHC in daily overhead labour costs to prevent bird raiding. Bird raiding on rice fields not only caused substantial economic losses but also had unintended social consequences. These included increased students’ absence from school and farmers' inability to attend and participate in family, community, and other social gatherings. The study highlights the need for practical and efficient methods to mitigate the effects of bird raiding. Given the significant economic and social impacts, it is crucial to develop strategies that effectively reduce bird raiding in rice fields.
