12.1.2(ii) IRRIGATION

Description

Quick Overview

Irrigation is crucial for ensuring crops receive adequate water, especially in rain-fed agriculture.

Standard

This section highlights the significance of irrigation methods in agriculture, discusses various irrigation systems used in India, and emphasizes the need for improved water management practices to support crop yields effectively.

Detailed

Detailed Summary

Irrigation plays a vital role in agriculture, particularly in regions where rainfall is unpredictable or insufficient. In India, with its diverse climate, different irrigation techniques are essential to sustain agricultural productivity. The section starts by explaining how most Indian agriculture relies on rainfall, with poor monsoons often leading to crop failures.

To mitigate this, irrigation systems such as wells, canals, river lift systems, and tanks are utilized to deliver water effectively to agricultural lands.

  • Wells: These include dug wells and tube wells that collect water from underground strata, ensuring a reliable source of water for irrigation.
  • Canals: These are extensive irrigation systems that distribute water from reservoirs or rivers to various fields.
  • River Lift Systems: Used when canal flow is insufficient, these systems draw water directly from rivers for irrigation.
  • Tanks: Small storage reservoirs that collect run-off water to supply it to crops.

To complement traditional methods, modern initiatives like rainwater harvesting and watershed management are introduced. These strategies involve constructing check-dams to enhance groundwater levels and reduce soil erosion.

The significance of irrigation lies not only in maintaining crop yields but also in supporting agricultural sustainability, ensuring food security for India's ever-growing population.
