Scene 4

[Audio] Impact of Climate Change on Subsistence Farming in South Africa: Climate change threatens subsistence farming, increasing food insecurity and poverty among rural populations. Over four million South Africans rely on subsistence farming, which faces challenges like soil erosion and crop losses due to extreme weather. This drives interest in alternative methods such as hydroponics. Hydroponic Farming: Methods: Includes Ebb and Flow, Deep Water Culture (D-W-C--), Wick Systems, Drip Systems, Aeroponics, and Nutrient Film Technique (N-F-T--). Advantages: Larger yields, less water usage, and independence from natural climate conditions. Challenges: Requires technical skills, though (A-I ) can help automate tasks..
