Which factor is likely to increase the need for a backup water source?

The need for a backup water source is significantly influenced by the increased demand for agricultural products. As agricultural production intensifies to meet food supply needs, farmers and growers often require more water to irrigate their crops effectively. Consequently, this heightened demand for water can lead to increased pressure on existing water sources, making them insufficient or unreliable, particularly during drought conditions or periods of low availability.

In such scenarios, relying solely on a primary water source may not be viable, prompting the necessity for a backup source to ensure consistent irrigation and crop health. This backup source could be another well, reservoir, or alternative water source that provides additional security against potential water shortages, therefore safeguarding agricultural productivity amidst fluctuating environmental conditions and growing demand.
