Savanni

Savanni is a term that primarily refers to the savanna, a tropical or subtropical grassland ecosystem characterized by a mixture of open plains and scattered trees. These regions are found across parts of Africa, South America, Australia, and Asia, covering approximately 20% of the Earth's land surface. Savannas are known for their high biodiversity, supporting numerous species of grasses, herbs, herbivores, and predators.

The climate of savannas typically features distinct wet and dry seasons, with annual rainfall ranging from 500 to 1500 millimeters. During the rainy season, the landscape is lush and supports a variety of plant life, while the dry season often results in a more arid environment with grasses and drought-resistant shrubs. Fire plays a natural role in savanna ecosystems, helping to control tree growth and promote the regeneration of grasses.

Economically, savannas are important for agriculture, pastoralism, and tourism. Many indigenous communities and modern farmers utilize these lands for livestock grazing and crop cultivation. However, savannas face threats from deforestation, overgrazing, agriculture expansion, and climate change, which can lead to habitat degradation and loss of biodiversity.

The term "savanni" may also be used in different contexts or as a variant spelling in some languages, but it generally refers to the same ecological and geographical concept. Conservation efforts are ongoing to balance sustainable use with preservation of these unique ecosystems, recognizing their vital ecological and cultural significance.
