• Ventilate your home regularly to limit indoor humidity.

Psychological Impacts Related to Climate Adaptation

Arriving in an environment with stronger sunlight and different seasonal rhythms can cause persistent fatigue (“climate jetlag”), sleep disorders, or temporary mood drops.

Recommended Strategies

• Take time to observe your own physical/psychological reactions to weather changes;
• Maintain a stable routine (sleep/meals/activities);
• Practice relaxation/meditation to manage anxiety related to change;

Key Takeaway: South African climate challenges require anticipation and continuous adaptation. Enhanced vigilance regarding sun protection, hydration, and active listening to bodily signals generally allows for a smooth acclimatization.

Strategies for Living with Extreme Climates in South Africa

Local residents and expatriates in South Africa adopt various strategies to adapt to temperature variations, especially in hot or dry climate zones.

Adapted Agricultural Practices:

• Use of drip irrigation systems to save water.
• Selection of drought-resistant crops like sorghum, millet, or certain maize varieties.
• Crop rotation and soil mulching to limit evaporation.
• Adoption of agroforestry techniques (trees planted around fields) to provide shade and reduce moisture loss.

Housing Equipment and Design:

• Construction with insulating materials such as hollow bricks, reflective roofing, or terracotta tiles that limit indoor heat.
• Installation of fans, efficient air conditioners, or reversible heat pumps in modern homes.
• Windows equipped with external shutters, heat-blocking films, or thick blinds to reduce direct solar impact.
• Simple systems like green roofs or integration of shaded spaces (covered terraces).

Essential Clothing and Accessories:

Typical list used by locals and expatriates:

• Wide-brimmed hats
• UV sunglasses
• Light clothing in cotton or linen covering arms and legs
• High-SPF sunscreen (SPF 50+)

Local Water Conservation Techniques:

Main practices used in arid regions:

• Rainwater harvesting via domestic tanks
• Reuse of greywater (from washing) for irrigation
• Strict limitation of garden watering during dry season
• Community awareness on reducing waste

Equipment	Main Function	Suited for Hot/Dry Climates
Water Tanks	Rainwater storage	Yes
Reflective Roofs	Reduction of indoor heat	Yes
Reversible Heat Pumps	Economical heating/cooling	Yes

Testimonials from Well-Adapted Expatriates:

“Upon arriving in the Karoo, I installed a water collector under each gutter. I also learned to cultivate my garden only with indigenous plants that survive without daily watering.”

— Jean-Pierre B., French expatriate

“The first months were difficult. But thanks to advice received from a local association, I changed my clothing habits; I now always wear a wide hat whenever I go out.”

— Sophie M., Swiss expatriate
