Analyse the differences between sources of irrigation between Coastal Andhra, Rayala Seema and Telangana in the United Andhra Pradesh and their consequences.

Coastal Andhra’s Canal Dominance

Extensive canal irrigation from Godavari and Krishna rivers through the delta systems and Nagarjuna Sagar canals supports water-intensive crops like paddy. The flat terrain and fertile delta facilitate large-scale surface water use, making canal irrigation the backbone of agriculture here.

Telangana’s Mixed Irrigation

Combines canal irrigation with tanks and groundwater; Mission Kakatiya has revived tanks, and micro-irrigation is promoted. The undulating terrain and historical tank systems support a hybrid irrigation model, while micro-irrigation initiatives aim to optimize scarce water resources.

Agricultural Productivity

Coastal Andhra’s canal irrigation enables high-yield paddy; Rayalaseema’s erratic water limits crops to drought-resistant millets and pulses. Telangana’s mixed irrigation supports diverse cropping but faces challenges from groundwater depletion.

Water Sustainability

Over-extraction in Rayalaseema and Telangana causes declining water tables; Mission Kakatiya improves tank water retention; Coastal Andhra faces waterlogging and salinity due to canal irrigation. Telangana’s tank revival and recharge efforts exemplify adaptive management.

Micro-Irrigation Expansion

Scaling drip and sprinkler irrigation in Rayalaseema and Telangana to reduce groundwater stress, building on successes like Mission Kakatiya.
