Results of the principal component analysis performed on the market price of cattle and small ruminants in 2014 and 2019 in a selection of monitored markets. The left hand biplots represent the values taken by the markets (arrows) and months (dots numbered from March to December in chronological order) on the first and second dimensions (the X and Y axis respectively). The color of the arrows corresponds to the cluster the markets were attributed to. The right hand maps represent the geographical location of the markets, with colors corresponding to their attributed cluster. The bottom graphs represent the value taken by the successive months on the first dimension in 2014 (plain line) and 2019 (dashed line) for cattle (left) and small ruminants (right). The plain and dashed vertical red lines correspond to the months of important religious celebrations where cattle and small ruminants are traditionally consumed in 2014 (plain) and 2019 (dashed) (Magal de Touba for cattle, Tabaski for small ruminants). Administrative boundaries were drawn using the GADM database of Global Administrative Areas (www.gadm.org).
