Types of Droughts
- Meteorological Drought: A situation where there is a prolonged period of inadequate rainfall that is characterised by an unfair distribution of the same over time and space.
- Agricultural Drought: Also known as soil moisture drought, characterised by low soil moisture that needs to support crops, leading to crop failure. Besides, if the gross cropped area under irrigation in a region is more than 30%, then that region is excluded from the category of drought-prone area.
- Hydrological Drought: If water availability in various storages and reservoirs such as aquifers, lakes and reservoirs falls below what the rainfall can refill.
- Ecological Drought: If a natural ecosystem's productivity falls because of water shortage and ecological distress, the ecosystem is induced to damage.

Meteorological drought:
Meteorological drought refers to a prolonged period of significantly below-average precipitation. It is characterized by a lack of rainfall or snowfall, which leads to a deficit in water supply. However, meteorological drought alone does not necessarily indicate a depletion of water resources, as it focuses solely on the lack of precipitation.
Hydrological drought:
Hydrological drought occurs when the availability of water in different storages and reservoirs, such as aquifers, lakes, and reservoirs, falls below what the precipitation can replenish. It considers the overall water balance, taking into account both inflows and outflows of water sources. Hydrological drought reflects the impact of meteorological drought on water resources and can have severe consequences on water availability for human and environmental needs.
Agricultural drought:
Agricultural drought specifically relates to the impact of water scarcity on agricultural activities. It occurs when the water deficit affects crop growth and production, leading to reduced yields and potential agricultural losses. Agricultural drought is closely linked to hydrological drought, as it depends on the availability of water for irrigation and other agricultural purposes.
Ecological drought:
Ecological drought refers to the impact of water scarcity on ecosystems and the natural environment. It occurs when the water deficit affects the health and functioning of ecosystems, including vegetation, wildlife, and aquatic habitats. Ecological drought can result in habitat degradation, loss of biodiversity, and disruptions in ecosystem services.
Explanation of the correct answer:
The correct answer is option 'B', which is hydrological drought. This is because hydrological drought considers the availability of water in different storage and reservoirs, taking into account both inflows and outflows, which directly relates to the depletion of water resources. When the availability of water falls below what the precipitation can replenish, it indicates a deficit in water supply and reflects the impact of meteorological drought on water resources. Therefore, hydrological drought is the appropriate term to describe the situation described in the question.
