India carries a huge livestock population. Small ruminants, namely, goats and sheep, play a vital role in securing the livelihood of small and marginal farmers and landless labourers. Such animals should not be blamed for the ecological degradation, soil erosion and desertification caused by human activities.
Desertification involves many countries featuring different ecological, economic, and social conditions. In Mediterranean Europe, high human pressure, economic development, and climatic changes combine to produce land consumption, soil erosion, salinization, and fire risk, all considered as key factors to start desertification processes.
Nigeria has a total land area of 983,213 km2 occupied by about 120 Million people: The interaction of these millions of people with their environment has left indelible mark on the landscape.
