Indian Climate, Agriculture, Water Resources and Disaster Management
Climate, agriculture and water resources are closely connected with the Indian economy and human life. Disaster management is also an important topic for UPSC and competitive exams.
Indian Climate
India experiences a monsoon type of climate. The climate is influenced by latitude, altitude, pressure systems and monsoon winds.
Major Seasons in India
- Winter Season
- Summer Season
- Southwest Monsoon Season
- Retreating Monsoon Season
The Southwest Monsoon brings most of the rainfall in India.
Factors Influencing Indian Climate
- Latitude
- Altitude
- Distance from the sea
- Pressure and winds
- Ocean currents
The Himalayas play an important role in protecting India from cold winds from Central Asia.
Monsoon Mechanism
Monsoon refers to seasonal reversal of winds. The Indian monsoon is mainly caused by differential heating of land and water.
Branches of Southwest Monsoon
- Arabian Sea Branch
- Bay of Bengal Branch
Kerala receives the first monsoon rainfall in India.
Agriculture in India
Agriculture is the backbone of the Indian economy. A large percentage of the population depends on agriculture for livelihood.
Major Cropping Seasons
- Kharif Crops
- Rabi Crops
- Zaid Crops
Kharif Crops
These crops are grown during the monsoon season. Examples: Rice, Maize and Cotton.
Rabi Crops
These crops are grown during winter. Examples: Wheat, Mustard and Gram.
Green Revolution
The Green Revolution increased agricultural production through the use of HYV seeds, fertilizers and irrigation.
Important Features
- High Yielding Variety Seeds
- Modern Irrigation
- Use of Fertilizers
- Mechanization
Punjab, Haryana and Western Uttar Pradesh benefited greatly from the Green Revolution.
Water Resources
Water is one of the most important natural resources. India depends heavily on rivers, groundwater and rainfall.
Sources of Water
- Rivers
- Lakes
- Groundwater
- Rainwater
Water Conservation
- Rainwater harvesting
- Watershed management
- Efficient irrigation methods
- Protection of water bodies
Drip irrigation helps in saving water and improving crop productivity.
Disaster Management
Disaster management refers to planning and measures taken to reduce the impact of natural and human-made disasters.
Types of Disasters
- Earthquakes
- Floods
- Cyclones
- Droughts
- Landslides
Cyclones
Cyclones are intense low-pressure systems formed over warm ocean waters.
Important Facts
- Tropical cyclones occur in the Indian Ocean
- The east coast of India is more cyclone-prone
- Odisha and Andhra Pradesh are highly vulnerable
Floods and Droughts
Floods
Floods occur due to excessive rainfall, river overflow and poor drainage systems.
Droughts
Droughts occur due to prolonged shortage of rainfall. They affect agriculture and water availability.
NDMA
The National Disaster Management Authority (NDMA) coordinates disaster management activities in India.
Objectives
- Preparedness
- Early warning systems
- Rescue and relief operations
- Rehabilitation
Important UPSC Facts
- Kerala receives first monsoon rainfall
- Kharif crops depend on monsoon rains
- Green Revolution increased food production
- Drip irrigation saves water
- NDMA manages disaster response in India
Quick Revision Box
