Editorial 1: ​Rain and repeat

Context

Excess rain is no excuse for damage caused by neglect of sluices 

Introduction

Heavy rains and floods in Andhra Pradesh and Telangana reveal how extreme weather interacts with governance and infrastructure. Consecutive years of excess precipitation, coupled with stressed reservoirs and weak urban planning, expose systemic shortcomings. While disaster management has saved lives, structural neglect and delayed reforms highlight the urgent need for resilient water and flood management strategies.

Changing Rainfall Patterns and Reservoir Stress

• Andhra Pradesh saw 27% of annual rainfall in just two days (2024); Vizianagaram logged 46% excess with some areas up to 90%.
• Consecutive years of extreme precipitation indicate monsoon shifts.
• Reservoirs like Srisailam (94%) and Nagarjuna Sagar (96%) had little buffer capacity during peak rains.
• The crisis is driven by excess rainfall in short bursts when storage systems are nearly full.

Infrastructure and Policy Gaps

• Tributaries and drainage channels (e.g., Budameru) have caused major flooding in Vijayawada.
• Unrepaired gates at Prakasam Barrage and collapsed floodbanks near Bhadrachalam worsened the situation.
• Urban flooding worsened by encroached stormwater channels, incomplete desilting, and concretised surfaces.
• Existing infrastructure is not maintained or upgraded, magnifying damage during extreme events.

Disaster Management and Future Preparedness

• Disaster management systems saved lives but remain focused on relief over risk reduction.
• Large funds (e.g., ₹1 crore per district in Telangana) are allocated for immediate relief, while floodbanks and diversion works remain incomplete.
• Recurring floods expose delays in Budameru works and opaque relief fund usage.
• Solutions: real-time hydrological modelling, stronger urban drainage, protection of permeable land, and continuous maintenance of flood infrastructure.
• Extraordinary rains may overwhelm systems, but using this as an excuse risks complacency over reform.

Conclusion

The recurring floods underline that extraordinary rains cannot be prevented but their impacts can be reduced. Real-time reservoir management, strengthened urban drainage, and continuous maintenance of floodbanks are essential. Both States must move beyond short-term relief to long-term resilience, ensuring policies are proactive rather than reactive, and infrastructure is prepared for a changing climate and unpredictable monsoons.
