Question

2.1 Describe how strong winds can influence crop production negatively.

Strong winds can have several negative impacts on crop production:

- The wind can damage the leaves, flowers, and fruit setting of plants, leading to reduced photosynthesis and lower production.
- Increased transpiration and evaporation can stress the crops, resulting in lower yield.
- Strong winds can uproot or blow over plants, causing total loss of production.
- The intensity of the wind can lead to smaller plants or deformities, negatively affecting growth.
- Wind may disrupt pollination, ultimately leading to a diminished crop yield.

2.2 Farm workers have the right to work in a safe environment.

2.2.1 Name the Act that provides for a safe workplace.

Occupational Health and Safety Act, 1993 (Act 85 of 1993).

2.2.2 Name FOUR protective measures that workers must consider when working with dangerous substances.

- Wash their hands after using the chemicals.
- Wear protective clothing like overalls with long sleeves.
- Never pour chemicals from hand to hand or allow them to be on a surface.
- Be properly trained to work with chemicals and never ingest them.
