Step 1: Answer question 1.3.5.
Farmers can implement several strategies to reduce the impact of drought on maize production.
- Planting drought-resistant maize varieties that are genetically adapted to survive with less water.
- Implementing water-saving irrigation techniques such as drip irrigation or precision irrigation to deliver water directly to the plant roots, minimizing waste.
- Practicing conservation tillage (e.g., no-till farming) to reduce soil disturbance, which helps retain soil moisture and improve soil health.
Step 2: Answer question 1.4.1.
The province in South Africa well-known for platinum mining is the North West province.
Step 3: Answer question 1.4.2.
Platinum is located in the North West province due to the presence of the Bushveld Igneous Complex, a unique geological formation rich in platinum group metals.
Step 4: Answer question 1.4.3.
Based on the cartoon, two positive social impacts of platinum mining are:
- Job creation: The cartoon explicitly shows "JOBS" as a benefit.
- Development of social infrastructure: The cartoon depicts "SCHOOL" and "CLINIC", indicating improved access to education and healthcare facilities.
Step 5: Answer question 1.4.4.
The infographic lists two negative environmental impacts of platinum mining:
- Pollution: This refers to air pollution from industrial emissions (smoke stacks shown) and potential water pollution from mining activities.
- Land degradation: This involves the destruction of natural landscapes, soil erosion, and habitat loss due to mining operations and waste disposal.
Step 6: Answer question 1.4.5.
Mining companies can implement the following strategies to ensure the long-term sustainability of platinum mining:
- Land rehabilitation: Restoring mined land to its original or an ecologically viable state after mining operations cease.
- Efficient resource management: Implementing advanced technologies to maximize platinum extraction while minimizing waste and energy consumption.
- Pollution control and waste management: Investing in technologies to reduce air and water pollution, and safely managing mining waste (tailings).
