For a significant portion of its life-saving medications, the industry relies on a concentrated cluster of manufacturers in a few foreign provinces. As highlighted by the Observer Research Foundation (Nov 2025): **"India still lacks a unified, constantly updated dashboard of its critical health import dependencies,"** leaving the national healthcare infrastructure reactive to external shocks, environmental shutdowns, and trade anomalies. +ShockMap is an operator-facing intelligence platform built for the Google Solution Challenge 2026. It turns weak early signals from trade, news, and policy sources into a clear operational workflow: -## The Solution -PharmaShield is an intelligence dashboard designed to map, monitor, and model India's pharmaceutical import dependencies.
