Why the Kaveri Delta Is Shrinking, and Farm Productivity With It -KA Shaji

The delta has shrunk by 20% because of diversion of land and climate change. Water-intensive agriculture and industrial practices are adding to the problem.

Despite being one of the oldest water-regulator structures in the world that is still functional, the Kallanai dam or the Grand Anicut looks almost empty with not much water to regulate. Located near Tiruchirapalli in Tamil Nadu, it was built across river Kaveri around 2000 years ago by then king Karikala Chola to divert water to the delta region to boost irrigation and also to avoid loss of crops to floods.

Downstream of Kallanai, the Kaveri river, among the most important rivers of south India, gives a poignant picture of large-scale encroachments and indiscriminate sand mining. Now, no water flows into the Bay of Bengal at Poompuhar, the celebrated coastal town where the river meets the sea.

“The subject of decades-long use and abuse by both Karnataka and Tamil Nadu, the river is in its deathbed,” lamented Swamimalai R. Vimalnathan, general secretary of the Thanjavur District Kaveri Farmers’ Protection Association. “In the future, we will not have the once perennial river to fight over. The water resources are receding and our once celebrated delta region is shrinking.”

Along with the imminent death of the river, Vimalnathan is pointing out another worrying factor that is threatening the very existence of this traditional ‘granary’ of Tamil Nadu. According to him, the delta region is shrinking fast with cultivable lands increasingly deteriorating into wastelands. To substantiate his claim, Vimal Nathan quoted findings of a study by S. Janakarajan, a retired faculty member with the Madras Institute of Development Studies (MIDS).

Supported by Indian Council of Social Science Research (ICSSR), the study had focused on change in land use patterns of the delta region in the last four decades. Based on his field level research, spread over three years, Janakarajan says that the delta shrunk already by 20% because of anthropogenic factors including diversion of land for non-agricultural purposes. He also cited climate change as a contributing factor.
