2.1 Environmental deficits in sa  (Page 4/4)

EXAMPLES: - Trees are felled for firewood.

- Useful water resources are over utilised.

b) It disrupts the ecological balance. It reduces the number of forests and as a result the number of trees. It contributes to the fact that the soil no longer is kept stable (compacted) by their root systems. The top soil therefore is very vulnerable, especially to water and wind erosion.

5. CONSIDER THE FOLLOWING:

Push factors : Poor and insufficient housing

Lack of basic services, such as: medical, educational services, etc. in rural areas

Few job opportunities

Physical problems such as: poor soil, low rainfall, consolidation of farms, farm murders, etc.

Poor wages

Uneconomical units

Pull factors: More and better housing

More job opportunities

Higher wages

Better and more basic services

Availability of high order services – supply examples

Means of communication, etc.

ACTIVITY1:

a) Low rainfall: Plant crops that adapt to rainfall figures

• Water shortage: Build catchment dams and water restrictions
• High population growth: Education
• Deforestation as a result of

Development: Plant natural forests

• Subsistence farmers - causes Scientific farming methods

Erosion:

2. a) - Not sufficient access to fertile soil

• Soil of inferior quality
• Not sufficient funds to purchase seed, implements and fertiliser
• Traditional farming
• No market for produce

3. a) Shortages that occur as a result of population growth. An expanding population demands more land, more food, etc. A larger demand for basic resources arises due to a growing population.

b) TABLE 4:

1) Urban areas grow more rapidly (3%) than rural areas in KwaZulu-Natal.

2) Informal settlements grow more rapidly (4%) than rural settlements in KwaZulu-Natal.

TABLE 5:

1) Approximately half of the urban dwellers in KwaZulu-Natal live in informal settlements.

Urban settlements accommodate most people (54,6%) in KwaZulu-Natal.

4. a) Shortages that arise as a result of the over-utilisation of particular resources precisely because these resources are available.

EXAMPLES: - Trees are felled for firewood.

- Useful water resources are over utilised.

b) It disrupts the ecological balance. It reduces the number of forests and as a result the number of trees. It contributes to the fact that the soil no longer is kept stable (compacted) by their root systems. The top soil therefore is very vulnerable, especially to water and wind erosion.

ACTIVITY 2:

1. Land densification
2. In irrigation areas (soil-)
3. – Do not scatter garbage
4. – Do not dump household or other refuse in rivers or water resources

– Recycling refuse
