Cyclone and Drought Management

India has suffered from cyclones, droughts and other natural disasters. They have destroyed lives and livelihoods as well as infrastructure. India’s varied geography and climate are factors that contribute to these disasters, which underscores the importance of effective management strategies. This article presents a comprehensive review of cyclone and dry spell management in India. The causes, the impacts, the strategies and some examples of effective interventions are all covered.

Cyclones: What you need to Know

What exactly is a cyclone?

The cyclone system is a rotating storm characterized by strong winds and a central area of low pressure. Cyclones are common in India’s Bay of Bengal, and Arabian Sea between May and Novembre.

The causes of Cyclones In India

1. Low-Pressure FormationWhen warm moist air rises off the surface of the ocean, a zone of low pressure is created.

2. Temperature: The sea surface temperature above 26.5°C is crucial for cyclone formation.

3. Atmospheric ConditionsIntensity of the cyclone depends on wind shear and humidity.

Cyclones and their impact

• Human displacementWinds of high intensity and flooding can force entire villages to leave their homes.
• AgricultureThe destruction of food crops is a major cause for insecurity.
• Damage to roads, buildings and utility systems.
• The economy is affected by losses in the agriculture sector.

India Drought

What is Drought?

A prolonged period with abnormally low rains can lead to scarcity of water. Drought affects the agriculture, water supply, energy production and health.

Different types of drought

1. Droughts caused by weatherBased on the amount of dryness as compared with a climate that is normal.

2. Drought in AgricultureWhen there is not enough moisture to support crop growth.

3. Droughts – HydrologicalAffected by prolonged drought conditions.

Droughts in India: What are the causes?

• Climatic VariabilityThe agriculture that is dependent on monsoons can be vulnerable to changes.
• Groundwater extraction that exceeds the permitted limitThe use of water in an unsustainable manner reduces the reserves.
• It is a soil degrading processLand management can worsen droughts.

Effects of Drought

• Food InsecurityReduced crop production can lead to famine.
• Economic CrisisFarmer’s incomes are reduced and they can be in debt.
• The Migration of PeopleAs individuals look for better job opportunities, rural-to-urban immigration is on the rise.

Cyclone management strategies
