Malnutrition Due to Climate Shocks and the Health Systems’ Resiliency in India
Introduction
India, despite significant strides in economic and social development, continues to grapple with the persistent challenge of malnutrition. The country bears a substantial portion of the global malnutrition burden, with children and women being the most affected. While poverty, food insecurity, and poor sanitation have long been identified as root causes, a growing body of evidence highlights climate change and climate-related shocks as critical emerging drivers. These shocks not only exacerbate food and nutrition insecurity but also test the resilience of India's health systems, particularly in vulnerable regions.
Climate Shocks: A Catalyst for Malnutrition
Climate shocks such as heatwaves, droughts, floods, and cyclones have increasingly disrupted food systems across India. These events directly affect agricultural productivity, reduce the availability of nutrient-rich foods, and drive up food prices, making it difficult for low-income households to access a balanced diet.
- Droughts in states like Maharashtra and Rajasthan have led to crop failures, impacting both food supply and income.
- Flooding in regions such as Assam and Bihar often destroys crops, displaces communities, and disrupts local food distribution systems.
- Extreme heatwaves reduce labour productivity, diminish household income, and lead to reduced food intake, especially among children.
In such contexts, children under five, pregnant women, and lactating mothers become particularly vulnerable to undernutrition and micronutrient deficiencies.
The Double Burden: Health Crises and Systemic Strain
In addition to food insecurity, climate shocks often result in outbreaks of waterborne diseases, acute respiratory infections, and other illnesses that compound malnutrition. For example, diarrheal diseases during floods deplete children's nutrient stores and reduce the body's ability to absorb nutrients, creating a vicious cycle of infection and undernutrition.
These combined effects place a severe strain on India’s health infrastructure, which is often under-resourced in rural and remote areas. Climate-induced displacement, for instance, often leads to overcrowding in temporary shelters with poor hygiene and limited access to healthcare.
Health Systems’ Resilience: A Critical Need
To effectively respond to and mitigate the effects of climate-induced malnutrition, India’s health systems must become more resilient and adaptive. This means:
- Strengthening primary healthcare systems with adequate nutrition services, including growth monitoring, supplementary feeding, and therapeutic care for severely malnourished children.
- Enhancing data systems to track nutrition outcomes in real-time, particularly in climate-sensitive districts.
- Training frontline health workers (ASHAs, ANMs, and Anganwadi workers) to recognise climate-related health risks and deliver targeted interventions.
- Improving coordination between health, nutrition, agriculture, and disaster management departments to ensure an integrated response to climate shocks.
Policy and Programmatic Interventions
Government schemes like POSHAN Abhiyaan, Integrated Child Development Services (ICDS), and National Health Mission play a pivotal role in addressing malnutrition. However, these programs must be climate-informed.
Policy efforts should focus on:
- Climate-resilient agriculture (e.g., millet promotion under the International Year of Millets 2023)
- Climate-proofing nutrition and health services in disaster-prone areas
- Building climate risk maps and integrating them with health program planning
Conclusion
Addressing malnutrition in India can no longer be seen in isolation from the growing threat of climate change. Climate shocks are intensifying existing vulnerabilities, disproportionately affecting marginalised communities and children. For India to achieve its nutrition goals under the Sustainable Development Goals (SDGs) and build a healthier population, it is imperative to strengthen the resilience of its health and food systems against climate-related risks.
A climate-resilient health system is not just a necessity; it is a lifeline for India’s most vulnerable citizens.
