INTRODUCTION. Nigerian Sudan Savanna Zone is situated between latitudes 9°3̍ and 12°31̍ N and longitudes 4° and 14°3̍ E which covers about million hectares representing about one quarter of Nigeria’s geographical area (Manyong et al., ).The region is characterized by high annual average temperature (°C), short wet season and long dry season ( months), abundant short. The South African Savanna Biome Programme was set up to develop the understanding necessary to predict changes in the ecosystem stability induced by both natural and man-made stresses.

Conditions are warm to hot in all seasons, but significant rainfall occurs for only a few months each year—about October to March in the Southern Hemisphere and April to September in the Northern Hemisphere.
Mean annual precipitation is generally 80 to cm (31 to 59 inches. The largest areas of savanna are found in Africa, South America, Australia, India, the Myanmar (Burma)– Thailand region in Asia, and Madagascar.

Definition Of Biomes Large biotic communities corresponding to vegetation belts or zones are called biomes. Biomes are described as any large natural terrestrial ecosystem.
The type of any biome is largely determined by climatic factors, especially rainfall and temperature. Thus, regions of the world with similar climates have similar biomes. The local biomes in Nigeria. After dealing briefly with the use and place of an ecological survey in a natural resources investigation, this paper considers the practical problems involved in the recognition of plant communities and species on aerial photographs.

This chapter provides a detailed assessment of the ecological and socioeconomic conditions for the Southwest Savanna. It also identifies important planning and management considerations and suggests management opportunities that are compatible with the ecology of the landscape.
Abstract. So far we have been concerned primarily with the problems of survey and planning on the intensively utilized cultivated land of Asia. But there still remain some limited areas of primary vegetation, much larger areas of secondary and terminal vegetation, and large areas of land with low population density and light : Robert Orr Whyte.
Soil Physical Conditions in Nigerian Savannas and Biomass Production The Savannas of Nigeria and Agricultural Production Nigeria is located in the tropical zone (between latitude 4o and 14oN, and longitude 2oE), with a vast area having savanna vegetation (Figure 1).This is a region that isFile Size: KB.

A tourism region is a geographical region that has been designated by a governmental organization or tourism bureau as having common cultural or environmental characteristics.
These regions are often named after a geographical, former, or current administrative region or may have a name created for tourism purposes. The names often evoke certain positive qualities of the area and suggest a. Woody plants are key components of African savanna ecosystems as they provide wildlife habitats, offer browsing to ungulates and are also a major source of fuel wood.
Disturbance events such as herbivory and fire negatively affect woody plant communities. However, some woody plants respond to disturbance events through resprouting.
In savanna ecosystems, woody plants co-occur with grasses and Author: Allan Sebata. The African savanna contains a diverse community of organisms that interact to form a complex food web.
A community is a group of organisms interacting in a specific region under similar environmental conditions. A food chain is a group of organisms linked in order of the food they eat, from producers to consumers, prey to predators, and.

Savanna ecosystems play a major role in the natural landscape and in the economic life of vast areas of the tropics. These grasslands are inherently fragile, yet Third World economic development makes human exploitation inevitable.
The question that remains is whether utilization of the savannas for agriculture and other purposes will create sustained economic growth or a desert waste 5/5(1).In accordance with their mandate and the reccomandations of their statutory bodies, FAO and UNEP agreed to undertake a reassessment of the present situation and current evolution of the forest resources of the tropical world within the framework of the Global Environment Monitoring System (GEMS).
