Water Logging – Causes, Effects And Remedial Measures

Water logging significantly hampers agricultural productivity and environmental health by saturating the soil and elevating the groundwater table.

Causes Of Water Logging

Water logging arises from both natural and human-induced factors, adversely affecting agricultural productivity and water management.

Over-Irrigation

Over-irrigation occurs when excessive water is applied to fields, leading to water-logged conditions detrimental to crop growth.

Seepage From Canals, Reservoirs, And Ponds

Seepage from unlined canals and reservoirs contributes significantly to water logging by raising the groundwater table, leading to adverse agricultural effects.

Inadequate Or Poor Drainage

Inadequate or poor drainage prevents the removal of excess water from the soil, leading to water logging and severe agricultural implications.

Flat Topography And Impermeable Subsoil

Flat topography and impermeable subsoil restrict water movement, leading to soil saturation.

High Groundwater Table

The high groundwater table can lead to water logging, affecting crop growth and soil health.

Deforestation And Urbanization

Deforestation and urbanization significantly contribute to water logging by reducing soil's water-holding capacity and replacing permeable surfaces with impermeable ones.

Monocropping And Traditional Farming Practices

Monocropping and traditional farming practices contribute significantly to water logging by promoting the continuous cultivation of water-intensive crops and inefficient irrigation methods.

Effects Of Water Logging

Water logging has various adverse effects on agriculture, the environment, infrastructure, and socio-economic conditions.

Agricultural Effects

Water logging negatively impacts agriculture by reducing crop yields and promoting soil degradation.

Environmental Effects

Water logging negatively affects soil health, groundwater quality, and biodiversity.

Structural And Infrastructural Effects

Water logging can severely weaken the structural integrity of buildings, roads, and utility services in affected zones.

Socio-Economic Impacts

Water logging creates significant socio-economic challenges for farming communities, leading to reduced incomes and health risks.

Remedial Measures Of Water Logging

This section discusses the various remedial measures that can be implemented to address water logging.

Improvement Of Drainage Systems

Improving drainage systems is vital for managing water logging through effective surface and subsurface strategies.

Surface Drainage

Surface drainage systems are vital for managing excess rainfall and irrigation water, helping to prevent water logging.

Subsurface Drainage

Subsurface drainage is a crucial solution designed to lower water tables and manage excess moisture in soils, thus preventing water logging.

Canal Lining

Canal lining is an essential remedial measure against water logging as it prevents seepage losses from irrigation canals.

Controlled And Efficient Irrigation

Controlled and efficient irrigation techniques minimize water wastage in agricultural practices.

Recharging Groundwater Through Wells

Pumping groundwater from wells and utilizing surface water efficiently can effectively lower the water table and contribute to sustainable water management.

Tree Plantation And Agroforestry

Tree plantation and agroforestry play a significant role in mitigating water logging by enhancing groundwater absorption and improving soil conditions.

Construction Of Interceptor Drains

Interceptor drains are crucial for controlling water logging by intercepting seepage from canals before it infiltrates agricultural land.

Land Grading And Leveling

Land grading and leveling are essential practices that optimize water distribution and reduce stagnation in agricultural fields.

Policy And Institutional Measures

This section outlines the importance of policy and institutional frameworks in effectively managing water logging through collaborative and structured approaches.
