Lesson Content/Board Summary

Ecology And Agricultural Production In Nigeria: Practical Application

Definition of Ecological Zones

An ecological zone, also known as an ecoregion or biogeographical region, is a large area of land or water that contains a geographically distinct set of natural communities and species. These zones are characterized by similar climate, vegetation, soil types, and animal life, which in turn dictate the types of agricultural activities that can thrive there.

Types and Locations of Ecological Zones in Nigeria

Nigeria is broadly divided into several ecological zones, primarily based on climatic conditions and vegetation. The major zones include:

1. Mangrove Swamp Forest: Located along the coastal areas, particularly in the Niger Delta region.
2. Freshwater Swamp Forest: Found inland from the mangrove swamps, also in the Niger Delta.
3. Rainforest (Tropical Rainforest): Covers the southern parts of Nigeria, extending from the coast into the interior, including states like Edo, Delta, Cross River, Ondo, Ogun, and parts of Oyo and Osun.
4. Derived Savannah: A transitional zone between the rainforest and the Guinea Savannah, often a result of human activities like farming and burning that degrade the forest.
5. Guinea Savannah: The largest ecological zone in Nigeria, covering a vast area north of the rainforest, including states like Kogi, Benue, Niger, Kaduna, and parts of Kwara.
6. Sudan Savannah: Found further north of the Guinea Savannah, characterized by drier conditions, in states like Kano, Katsina, Sokoto, Borno, and Yobe.
7. Sahel Savannah: The driest zone, located in the extreme northeastern part of Nigeria, bordering the Sahara Desert, primarily in Borno and Yobe states.

Features and Agricultural Products of the Forest Ecological Zone

The Forest Ecological Zone in Nigeria primarily refers to the Rainforest and Freshwater Swamp Forest areas. Historically, these areas supported dense populations due to their agricultural potential.

1. Features:
   1. High annual rainfall (over 1500mm).
   2. High humidity and temperatures throughout the year.
   3. Dense, multi-layered vegetation with tall trees, climbers, and epiphytes.
   4. Rich biodiversity.
   5. Lateritic soils, which can be fertile but are prone to leaching.
2. Agricultural Products:
   1. Cash Crops: Cocoa, oil palm, rubber, kola nut, timber. These crops have historically been major export earners for Nigeria.
   2. Food Crops: Yam, cassava, cocoyam, plantain, maize, vegetables.
   3. Livestock: Limited due to tsetse fly infestation, but poultry and small ruminants are common.

Features and Agricultural Products of the Savannah Ecological Zone

The Savannah Ecological Zone encompasses the Derived, Guinea, Sudan, and Sahel Savannahs, with the Guinea and Sudan Savannahs being the most agriculturally significant. Historically, these zones supported large empires and kingdoms due to their grain production and livestock.

1. Features:
   1. Distinct wet and dry seasons.
   2. Moderate to low annual rainfall (ranging from 600mm to 1500mm).
   3. Dominant vegetation consists of grasses with scattered trees and shrubs (e.g., baobab, shea butter trees).
   4. Soils vary from sandy to loamy, often less fertile than forest soils but good for specific crops.
   5. Temperatures are generally high, especially during the dry season.
2. Agricultural Products:
   1. Cash Crops: Groundnuts, cotton, beniseed, shea butter. Groundnuts and cotton were historically significant export crops.
   2. Food Crops: Millet, sorghum (guinea corn), maize, rice, cowpea, yam (especially in the southern Guinea Savannah), cassava.
   3. Livestock: Cattle, goats, sheep, and poultry. The savannah zones are traditionally known for extensive livestock rearing, particularly by nomadic pastoralists.
