Tag: equatorial climatic region

In equatorial region the temperature is high throughout the year, the annual average temperature is about 27 degree calcious. Rainfall is heavy and distributed throughout the year. The annual average rainfall is about 250cm. The constantly high temperature and all the year round rainfall helps to produce the most luxuriant evergreen vegetation in the region. So the forests of equatorial region are also known as evergreen. 

In forestry and ecology, understory comprises plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade tolerant.

What makes up most of the Canopy Layer is a tangled mix of vegetation including branches, vines and trees of different sizes. The trees rise to as much height as possible to gain maximum sunlight. 

Tropical diseases encompass all diseases that occur solely, or principally, in the tropics. In practice, the term is often taken to refer to infectious diseases that thrive in hot, humid conditions, such as malaria, leishmaniasis, schistosomiasis, onchocerciasis, lymphatic filariasis, Chagas disease, African trypanosomiasis, and dengue.

The equatorial region extends up to 10 degrees North and 10 degrees South in both the hemisphere. Here Climate is uniform, the high temperature throughout the year. The annual average temperature is about 27 degrees celsius. The daily range of temperature is between 10 degrees celsius. So the winter season is absent in the equatorial region.

Tropical rainforests have four layers: Emergent Layer, Canopy Layer, Understory, Forest Floor. 

The Kubu are southern Sumatra's indigenous inhabitants. As traditional hunters and gatherers, they have inhabited the lowland tropical forests of Jambi and South Sumatra provinces for centuries, where they survive by gathering an enormous variety of edible forest products, and hunting.

The African Pygmies (or Congo Pygmies) are a group of tribal ethnicities, traditionally subsisting in a forager and hunter-gatherer lifestyle, native to Central Africa, mostly the Congo Basin.

The Semang are the Negrito and Austric ethnic groups of the Malay Peninsula. They are found in Perak, Kedah and Pahang regions of Malaysia.

Shifting cultivation combines farming with forested habitats. It is also called swidden or slash and burn and is commonly found throughout the Amazon and other tropical regions worldwide. Shifting cultivation systems are designed to adapt to the soil and climatic characteristics like lower soil fertility, high precipitation, and fast leaching of nutrients.
