Economic impact assessment of foot-and-mouth disease burden and control in pastoral local dairy cattle production systems in Northern Nigeria: A cross-sectional survey.

Milk has been envisaged as a major source of high-quality protein and bioavailable nutrients to humans. Its production is constraint by foot and mouth disease (FMD), a contagious viral disease of very high economic importance worldwide. This study was aimed at assessing the economic impact of FMD in pastoral dairy cattle herds in Nigeria and determines returns to investments in its control to better inform policy decisions. An interview questionnaire-based cross-sectional study was conducted in 660 nomadic and agro-pastoral dairy cattle herds in 2019. Economic impact analyses were conducted using the total economic cost and benefit-cost analysis models. Of the 660 pastoralists enrolled, 92.6% (n = 611) participated. Nomadic pastoralists constituted 50.7% (n = 310) of the respondents while 49.3% (n = 301) were agro-pastoralists. Most of the respondents (66.4%, n = 406) had no formal education. The value of visible losses to the herders was estimated at USD 15,591,694.30 and the cost of control by treatment of secondary infections was USD 463,673.70. The economic impact of FMD due to production losses and costs of treatment to pastoralists was estimated to be USD 16,055,368.00. Return on investment in FMD control was positive with a benefit-cost ratio of 33.6. The estimated total economic costs due to FMD have indicated that it is a disease of high economic importance to dairy production herds and must be controlled to assure food security, local incomes to herders, and protein requirement of human population, especially the children in FMD endemic countries.
