Human uses of the savannah
Sustainable management of the savannah
Conservation is the key to protecting the Serengeti for future generations. A sustainable future could be achieved if the following policies are adopted:
- Local people employed by investors.
- Respect for local cultures and customs.
- Local people should receive some financial rewards from tourism.
- Sustainable methods are used in order to protect the environment.
- Improved conservation education programmes for local communities and farmers.
Possible strategies to achieve these goals:
- Harvesting branches rather then whole trees to prevent deforestation, soil erosion and desertification.
- Controlled burning of grassland to avoid wildfires.
- Crop rotation to keep a varied supply of nutrients in the soil and prevent soil erosion and desertification.
- Stone lines along the soil contours keep it in place, prevent erosion and improve crop yields. Projects such as this can involve the whole community and give them a sense of ownership and responsibility.
- Managing grazing land to avoid overgrazing, soil erosion and desertification.
Solutions to desertification - some disadvantages
- Afforestation - newly planted trees need water, which will be a problem in a drought stricken region.
- Building stone lines - reduces soil erosion, but is a labour intensive process which diverts the community from tasks essential to their survival.
- Decreasing livestock - solves the problem of overgrazing but requires people to adapt if they rely on cattle or goats for their livelihoods.
