Lesson Content/Board Summary

Ecology And Agricultural Production In Nigeria: Features And Agricultural Products Of The Savannah Ecological Zone In Nigeria

Location and General Characteristics of the Savannah Ecological Zone

The savannah ecological zone in Nigeria covers a vast area, primarily stretching across the central and northern parts of the country. It is characterized by grasslands with scattered trees and shrubs, forming a transition between the southern forest zones and the northern desert-like regions.

The zone is generally divided into three sub-zones:

1. Southern Guinea Savannah: This is the wettest part, bordering the forest zone, with taller grasses and more dense tree cover.
2. Northern Guinea Savannah: Drier than the Southern Guinea, with shorter grasses and more scattered trees.
3. Sudan Savannah: The driest part, bordering the Sahel, with very short grasses and sparse, drought-resistant trees.

Features of the Savannah Ecological Zone in Nigeria

The savannah zone possesses distinct features that influence its agricultural potential:

1. Climate:
   1. Rainfall: Characterized by a distinct wet season (May to October) and a dry season (November to April). Rainfall decreases from south to north, ranging from about 1000mm to 500mm annually.
   2. Temperature: Generally high throughout the year, with average temperatures between 25°C and 30°C. There can be significant diurnal temperature variations, especially during the dry season.
   3. Seasons: A long dry season and a relatively short wet season, which dictates farming cycles.
2. Vegetation:
   1. Grasslands: Dominant vegetation type, varying in height and density depending on rainfall. Taller grasses in the south (e.g., elephant grass) and shorter, sparse grasses in the north.
   2. Scattered Trees: Deciduous trees that shed leaves during the dry season to conserve water. Common trees include baobab, shea butter, locust bean, and acacia.
   3. Shrubs: Various drought-resistant shrubs are also present.
3. Soil:
   1. Lateritic Soils: Predominantly reddish-brown lateritic soils, which are generally less fertile than forest soils due to leaching and low organic matter content.
   2. Drainage: Soils can be well-drained in some areas, but hardpans can form, affecting water infiltration.

Agricultural Products of the Savannah Ecological Zone in Nigeria

The climate and soil conditions of the savannah zone favour specific types of crops and livestock farming:

1. Crops:
   1. Cereals: Major cereal crops include millet, sorghum (guinea corn), maize (corn), and rice (especially in riverine areas). These are staple foods in the region.
   2. Legumes: Groundnuts (peanuts) and cowpeas (beans) are widely cultivated, providing protein and improving soil fertility.
   3. Root Crops: Yams and cassava are grown, particularly in the southern parts of the savannah, where rainfall is higher.
   4. Cash Crops: Cotton is a significant cash crop, especially in states like Katsina, Kano, and Kaduna. Sesame and soybeans are also gaining importance.
2. Livestock:
   1. Cattle: The savannah is Nigeria’s primary cattle-rearing zone, with large herds of Fulani and Shuwa breeds. The extensive grasslands provide pasture.
   2. Goats and Sheep: Widely kept for meat and milk, thriving in the savannah environment.
   3. Poultry: Local chickens and guinea fowls are common.

Historical Context and Significance of Agriculture in the Savannah Zone

Historically, agriculture in the savannah zone has been the backbone of many Nigerian societies, particularly the Hausa, Fulani, Kanuri, and Nupe kingdoms. The ability to cultivate grains and raise livestock supported large populations and led to the development of complex social and political structures.

1. Early Settlements: The availability of arable land and grazing areas encouraged early human settlements and the formation of powerful states like the Kano and Borno Empires, whose economies were largely agrarian.
2. Trade Routes: Agricultural surpluses from the savannah, such as grains, cotton, and livestock, were crucial for trans-Saharan trade and internal trade networks, linking the region to North Africa and other parts of West Africa.
3. Economic Foundation: Agriculture provided the primary source of wealth, food security, and raw materials for local industries (e.g., textile production from cotton, leatherwork from animal hides).
4. Cultural Impact: The agricultural practices and pastoralism shaped the cultural identity and traditions of the people in the savannah, influencing their festivals, social organization, and daily life.
5. Colonial Influence: During the colonial period, the British further exploited the agricultural potential of the savannah, promoting cash crops like groundnuts and cotton for export, which integrated the region more deeply into the global economy.
