Fertilizer application primarily influences crop yield and quality, not directly affecting water use efficiency.

Drip irrigation is designed to deliver water directly to the root zone of plants, minimizing water evaporation and optimizing water use.

Rainwater harvesting, greywater reuse, and xeriscaping are all effective methods for conserving water in urban environments.

Optimizing water use efficiency in industries aims to reduce water consumption and associated costs while maintaining or improving production levels.

Efficient irrigation methods typically reduce water consumption and improve crop yield without increasing fertilizer requirements.

Crop water requirement refers to the amount of water needed by a crop to complete its growth cycle under specific environmental conditions.

Mulching involves covering the soil surface with organic or inorganic materials to reduce evaporation and conserve soil moisture.

Optimizing water use efficiency in households aims to reduce water consumption and associated costs while maintaining or improving the quality of life.

Increased fertilizer application is not a water conservation strategy but rather a crop management practice that influences crop yield and quality.

Crop yield index represents the ratio of actual crop yield to the potential yield under ideal conditions, reflecting the efficiency of crop production.

Water recycling, process optimization, and the adoption of water-efficient technologies are all effective strategies for reducing water consumption in industries.

Non-revenue water refers to the water lost during distribution and conveyance due to leaks, unauthorized connections, and metering inaccuracies.

Expansion of water supply infrastructure is not a water conservation strategy but rather an approach to meet growing water demand.

Water footprint refers to the amount of water used to produce a unit of food, considering the water consumed throughout the supply chain.

Increased fertilizer application is not a method for improving irrigation efficiency but rather a crop management practice that influences crop yield and quality.
