Question

In which situation would hydroponics be most useful for sustainable farming?

1. a temperate area with too much direct sunlight
2. a tropical area facing deforestation
3. a mountainous area facing erosion
4. a desert area with limited rainfall

Answer 1

Hydroponics would be most useful for sustainable farming in a desert area with limited rainfall. In such an area, traditional farming methods are often not feasible due to the lack of arable land and unreliable water supply. Hydroponics allows for crops to be grown indoors with controlled water and nutrient supply, minimizing water usage while maximizing crop yield. It is a sustainable method of farming that can help to address food security challenges in arid regions.
