Geoengineering in India: Concepts, Challenges, and Future Directions

Concept and Application of Geoengineering

Geoengineering refers to large-scale interventions in Earth’s natural systems aimed at mitigating climate change effects. In India, this field is gaining traction, focusing on innovative methods such as carbon capture, afforestation, and weather modification. These interventions seek to address the pressing challenges posed by climate change and promote sustainable development.

Challenges and Considerations in Geoengineering

While the potential benefits of geoengineering are significant, several challenges must be addressed:

• Environmental Impact: Each geoengineering technique requires thorough evaluation to assess its long-term environmental consequences. Understanding how these interventions might alter ecosystems is crucial.
• Regulatory Framework: India must establish robust regulations to ensure safe and ethical geoengineering practices. This includes guidelines for research, implementation, and monitoring of geoengineering projects.
• Research and Development: Indian institutions are increasingly engaged in exploring geoengineering, particularly in the realms of renewable energy and carbon sequestration. This research is essential for developing effective strategies to combat climate change.

Potential Geoengineering Projects in India

Several potential projects highlight the application of geoengineering techniques in India:

• Solar Radiation Management: This technique aims to reflect a small percentage of sunlight back into space to cool the planet.
• Ocean Fertilization: Enhancing the growth of phytoplankton in oceans could absorb more carbon dioxide from the atmosphere.
• Enhanced Weathering: This process involves spreading minerals that chemically react with carbon dioxide, thereby removing it from the atmosphere.

India's Global Context in Geoengineering

India’s approach to geoengineering is particularly important due to its vast population, reliance on agriculture, and susceptibility to climate change impacts. The country’s strategies must consider its unique socio-economic context and the potential risks associated with geoengineering interventions. By prioritizing sustainable practices, India can lead the way in innovative climate solutions.
