Kerala backwaters

The Kerala backwaters are a vast network of brackish lagoons and canals. This labyrinthine system runs parallel to the Arabian Sea along the Malabar coast. It is located in the state of Kerala in south-western India.

The system includes interconnected lakes, rivers, and inlets. It is formed by more than 34 backwaters. Five large lakes are linked together by both natural and man-made canals. These waterways are fed by 38 different rivers. The network is so large that it extends across nearly half the length of Kerala state.

The formation of these backwaters began with the action of waves and shore currents. These forces created low barrier islands across the mouths of many rivers. These rivers flow down from the Western Ghats mountain range. This process resulted in the unique landscape seen today. The backwaters are categorized into different types. Out of the 34 backwaters, 27 are located near or parallel to the Arabian Sea. The remaining 7 serve as inland navigation routes.

A defining feature of this region is its brackish water. Brackish water occurs where freshwater from rivers meets saltwater from the Arabian Sea. This creates a unique ecosystem for many species. You can find crabs, frogs, and mudskippers in the water. Water birds like terns, kingfishers, darters, and cormorants live here. Animals such as otters and turtles also inhabit the area. Lush plants like palm trees and pandanus shrubs grow along the banks.

To protect agriculture, a barrage was built near Thanneermukkom. This structure prevents saltwater from entering too deep into the system. This keeps the water fresh for irrigation purposes.

The Vembanad Lake is a central part of this network. It is the largest lake in Kerala and the longest lake in India. It covers a massive area and contains a large network of meandering canals.

Many important locations sit within this lake, including Kochi city, Kuttanad, and Kumarakom. Other notable lakes in the region include Vellayani, Pookode, and Sasthamcotta. Sasthamcotta is the largest of the freshwater lakes. The backwaters are also globally significant. Three sites are listed under the Ramsar Convention as wetlands of international importance. These are Ashtamudi Lake, Sasthamkotta Lake, and the Vembanad-Kol wetlands.

Human history and economy are closely tied to these waters. For centuries, local people have used the backwaters for transport, fishing, and agriculture. The Kettuvallam, or traditional houseboat, played a major role. These were originally large grain barges used to transport rice from fertile fields. They featured wooden hulls with thatched roofs. Some were even used as living quarters by royalty.

Today, more than 2,000 of these boats serve the tourism industry. They have been converted into floating cottages with bedrooms and dining areas.

Visitors often hire them to experience the scenery while staff cook local Kerala food on board.

The Kuttanad region is a particularly important part of the landscape. It is known as the "Rice Bowl of Kerala" because of its massive paddy fields.

This region is geographically unique because it is very low-lying. Farming in Kuttanad happens between 1.2 and 3.0 metres below sea level. Because of this special system, the Food and Agriculture Organization declared it a Globally Important Agricultural Heritage System in 2013.

This area is crisscrossed by waterways that irrigate crops like rice, cassava, banana, and yam.

Cultural excitement often centers on the Chundan vallams, or snake boats. These are narrow boats that can hold about one hundred oarsmen. The raised prow resembles the hood of a snake.

These boats were once used by local rulers to move soldiers during wars. Now, they are used for the Vallam Kali, or boat race. One famous event is the Nehru Trophy Boat Race. This 1.5 km race was established after Jawaharlal Nehru visited in 1952. Other major races include the Thazhathangadi boat race and the Kumarakom Boat Race. These events draw thousands of spectators to the riverbanks.

Modern development has brought both opportunities and challenges. Tourism has transformed places like Ashtamudi Lake into busy destinations with many resorts.

In Kollam, initiatives like "Jeevananu Ashtamudi" have introduced electric boats and floating gardens. However, the rise of motorized houseboats has caused concerns. The diesel engines and outboard motors can pollute the fragile ecosystem. Despite these challenges, the backwaters remain a vital part of Kerala's economy and culture. They continue to support fishing, boatbuilding, and the coir industry.
