Water Conservation and Management

Drip system will be the best method to be adopted for watering fruit plants, gardens and trees. This system provides water to plants drop by drop and water is not wasted at all. Sprinkler system is best for sandy soil. Lever system and pulley system, being traditional methods, are less efficient. 

This is the correct option, as excessive rainfall is not a reason responsible for the scarcity of fresh water. Rather, excessive rainfall is good as it increases the supply of fresh water.

This is the correct option. Eucalyptus trees should be planted along sewage ponds as they absorb all surplus wastewater rapidly and release pure water vapour into the atmosphere.

River water is harder than rain water because it flows over rocks and soil, dissolving minerals like calcium and magnesium salts along the way. Rain water is essentially distilled water before it hits the ground.

Capillary water is the water held in the soil pores against the force of gravity due to surface tension and adhesive forces.

Agriculture accounts for the largest global consumption of freshwater, primarily for irrigation of crops.

Standard traditional lifts like the Washer Rahat or common hand pumps are generally not efficient or designed for depths of 8-10 meters without specialized modifications or power assistance.

The swing basket (Bedi) is a traditional, simple, and widely used manual tool for lifting water from shallow wells or water bodies in many agricultural regions. While other options like the Persian wheel are mechanical, the swing basket is historically the most common manual method for small-scale irrigation.

Irrigation methods are categorized based on how water is applied to the field. Surface, sprinkler, and drip irrigation are all widely recognized and used methods in modern agriculture.

This is the correct answer. 

This is the correct option. Oceans are not the source of fresh water.

This is the correct option as all of the above are the uses of water.

This is the correct option, as all of the above given steps are necessary for the conservation of water.

This is the correct option. Of the total water available, 0.006% is fit for human consumption.

This is the correct option, as using running shower for bathing will result in more wastage of water and it will not help in the conservation of water.
