Rangelands in Burkina Faso are vital for feeding animals, but they are being overused due to climate changes and grazing. A study in the Sahelian zone of Burkina Faso looked at different types of pastures and how they change throughout the year. They found that some areas have high pasture production, while others have low production. Pasture production decreases quickly in the rainy season, which could lead to animals not having enough food in the dry season.
