The rapid spread of the invasive crop pest, the fall armyworm (Spodoptera frugiperda), across Africa in recent years has attracted considerable interest, especially the effect on maize farmers. The purpose of this study is to understand and assess the economic costs of the fall armyworm invasion in Ghana under different control scenarios. Three different scenarios are modelled: one with no farmer applied control measures, one with limited control measures and one with proactive control measures that were used in Ghana in 2017. Maximum, minimum and mid-range estimates of losses are presented for the second and third scenarios. The study is based on data available from CABI surveys, the Ministry of Food and Agriculture in Ghana and FAOSTAT.
The rapid spread of the invasive crop pest, the fall armyworm (Spodoptera frugiperda), across Africa in
recent years and the resulting dramatic impact on crop production has attracted considerable media
interest, especially the effect on maize farmers who have been battling to save their crops. The crisis has led to substantial efforts by governments across Africa to help farmers control the pest and
reduce the effect on the maize crop. The outbreak has also been reported in scientific publications; the latter also providing good reviews of the identification, biology, ecology and behaviour
of the pest (see: Goergen et al 2016, Cock et al 2017, Abrahams et al 2017). However, little research has been carried out on the economic impact of the pest and whether concerted efforts to control FAW
can limit the economic effect on smallholder farmers in Africa. Thus, the aim here is to focus on the economics of the pest in Ghana as a case example. We model three different scenarios to assess
whether the actions taken to control FAW reduced the economic losses experienced within the country due to FAW.
