Researchers then used high-resolution satellite imagery to measure the extent of Africa’s grasslands, defined as areas that receive 300 to 1,500 millimeters of rain annually. The livestock rearing and farming conducive to jackal and wildlife survival, are now being replaced by industrialization and unsustainable agricultural practices.
