Explain how farmers can practice sustainable use of rangeland to prevent serious environmental harm to grasslands. give 3 specific ways this can be done.

For the answer to the question above, Clearing is a common part of developing extensive grassland for grazing. Where land is being developed for crops or sown pasture, clearing may involve some removal of stones, termite hills, and other obstructions, but, for extensive grazing, clearing usually involves removing or thinning woody vegetation to improve access and grass growth or to reduce tsetse fly habitat.
The second one is Bush control which is necessary for many grassland types; it is a maintenance activity, while bush clearing is development. Bush encroachment usually indicates faults in the management system and is associated with high grazing pressures; several mechanisms are involved according to vegetation type and management system. Unpalatable shrubs may increase when the more palatable ones are overgrazed; if little dry herbage remains in the non-growing season there may not be hot enough fires to control the bush.
The third one is Fencing which is widely used in the development of commercial grazing enterprises to delimit properties and subdivide them for ease of management. Block size is generally large on low-yielding grasslands since fencing and fence maintenance are costly; this can lead to uneven stock distribution. Fences are also used to protect forages and hay land within properties.
