A Fulani herdsman guides cattle in the area surrounding Bermo, on June 27, 2019. - Higher temperatures, shifting winds and moisture levels that alter rainfall patterns, sandstorms, torrential rain -- all can change the quality or even the location of pasture on which migrating herders depend. This year, for the Fulani, has been relatively good. The herdsman were able to draw on stocks of animal feed to help them survive stress points, while timely rainfall on some areas of the migration trail helped tender young grass to grow. But whether this respite endures is the big question. (Photo by Marco LONGARI / AFP) (Photo by MARCO LONGARI/AFP via Getty Images)
