"Fragmented institutional architecture is the biggest barrier to integrated climate action in Indian cities." Discuss with reference to heat stress policies and urban local bodies.

Urban heat is simultaneously a climate, labour and public health problem, yet in India each of these sits with a different ministry. With 2.4 billion workers globally exposed to excessive heat, WHO-WMO now urge national occupational heat-health policies [1] — a demand India's fragmented urban set-up struggles to meet. Fragmentation is a major barrier, though not the only one.

How fragmentation manifests in heat stress policy

• Vertical split: climate policy rests with MoEFCC through the NAPCC (2008) and its 8 missions [2]; occupational safety with the Ministry of Labour & Employment, which issued the 2025 nationwide heatwave advisory covering rescheduled work hours, rest areas and ESIC heat-stroke help desks [3]; urban governance with MoHUA. No single agency owns the intersection.
• Advisory, not statutory: the Labour Ministry's measures reach workers only if States and employers act [3]; municipal sanitation contracts rarely embed them.
• Mission-level gap: NAPCC's Sustainable Habitat Mission targets urban resilience but does not link it to occupational heat health [2].
• Capacity deficit at ULBs: State Action Plans on Climate Change are drafted at State level, while implementation falls on Urban Local Bodies lacking dedicated climate cells, budgets or heat data.
• Who pays the price: outdoor sanitation workers, mostly contractual and Dalit, face urban heat island effects while falling outside the Factories Act, 1948 and the BOCW Act, 1996.

Why fragmentation is not the whole story

• Even a unified agency needs finance; ULBs' weak own-revenue base limits shaded rest shelters or cool roofs.
• Ahmedabad's Heat Action Plan shows a determined ULB can act within the existing structure.
• Data gaps — few cities measure worker heat exposure — persist regardless of institutional design.

Fragmentation is therefore the binding constraint, but convergence must be paired with capacity. A statutory heat-health protocol in municipal contracts, a nodal climate-health cell in every ULB, and untied climate finance under the 2031–35 NDC's just-transition commitment [4] can turn advisories into entitlements, realising Article 21's promise of a safe working life.
