WEEK FOUR
TOPIC: FOREST MANAGEMENT IN NIGERIA
MANAGEMENT OF THE FOREST
The following are management practices that will ensure a constant supply of timber in the forest:
- FOREST REGULATION:
These are laws promulgated by government in the form of edicts, decrees and bye laws to prevent people from exploiting or indiscriminate tapping of forest resources.
- The prohibition of bush burning
- Ban on indiscriminate cutting of timber trees
- Encouraging people to plant trees
- Ban or collection of leaves and firewood from the forest
- Ban or farming in forest reserves
- Ban or cutting down of under aged trees
- People are to obtain licences so as to secure the permission to enable them cut down trees for human needs.
- SELECTIVE EXPLORATION
This is the process of cutting or harvesting only mature trees in the forest
ADVANTAGES OF SELECTIVE EXPLORATION
- It ensures the concentration of selected species of timber in the forest
- It protects soil from erosion
- It ensures continuous supply of timber
- It serves as revenue base for the government
- It prevents indiscriminate felling of timber
DEFORESTATION
This is the continuous or indiscriminate removal of trees without replacing them. It is the clearing, felling, cutting or thinning of forest trees by humans without planting another trees fro replacement.
CAUSES OF DEFORESTATION
- Unfavourable climatic factors such as draught, wind blast etc
- Man’s farming activities such as bush burning, shifting cultivation etc.
- Timber exploitation
- Mining/industrialization
- Natural disasters
- Bad government policies
EFFECTS OF DEFORESTATION
- It encourages soil erosion.
- It leads to reduction in fertility of soil.
- It reduces the amount of rainfall in an area
- It reduces soil moisture content
- It increases leaching of plant nutrient
- It destroys the microclimate and warms up the environment
- It may lead to desert encroachment
REGENERATION
Regeneration is the process of forest re-growth after it has been exploited. It is a deliberate effort to grow trees.
TYPES OF REGENERATION
- Natural Regeneration: in this type there is re growth of new plants from the old stump
- Artificial regeneration: this involves the planting of new forest seedlings in a deforested area.
ADVANTAGES OF NATURAL REGENERATION
- It is less expensive when compared with the artificial regeneration
- It does not require formal stages in plantation establishment
- It brings about the stabilization of natural ecosystem
- It does not require special management skill
AFFORESTATION
This is the process of establishing forest plantations in any area. Afforestation is the establishment of a forest or stand of trees in an area where there was no previous tree cover
ADVANTAGES OF AFFORESTATION
- It leads to addition of organic matter
- It provides regular supply of raw materials e.g timber for industries
- It prevents desert encroachment
- It increases forest fauna (wild life) in the area concerned
- It prevents leaching of plants nutrient
- It increases soil moisture retention
- It increases the amount of rain fall
- It improves the soil structure
TAUNGYA SYSTEM
Taungya system is defined as the planting of arable crops at early stage of forest establishment and the arable crops are harvested before the trees form canopies.The taungya is a system whereby villagers and sometimes forest plantation workers are given the right to cultivate agricultural crops during the early stages of forest plantation establishment. Cultivation is often allowed to continue until trees shade crops due to canopy closure.
CONDITION NECESSARY FOR THE PRACTICE OF TAUNGYA SYSTEM
The conditions which may favour the practice of taungya system include:
- Scarcity of land
- Over population
- Unemployment
- Government policies
- Low standard of living
ADVANTAGES OF TAUNGYA FARMING
- Varieties of crops are harvested
- There is availability of crop produce throughout the year
- When leguminous crops are used they fixed nitrogen to the soil
- Solves the problem of land scarcity
- It increases the income of the farmer
DISADVANTAGES OF TAUNGYA FARMING
- Reluctance in releasing fertile soil
- Cultivation of selected crops
- Competition between crops and trees
- Inability of some crops to survive
Presentation :
The topic is presented step by step
Step 1: The class teacher revises the old topic
Step 2: The class teacher introduces the new topic
Step 3: The class teacher allows the pupils to give their own contributions and gives room for pupils” participation
Class Teacher and Pupils Activities. Interaction or Participation
This involves class teacher and pupils’ interaction, conversation, imitation or modeling through discussion, play method or just by recitation or asking and answering questions that are related to the topic that has just been taught.
