The theme for the 21st Annual Colloquium is “Mission LiFE: Ensuring Environmental Sustainability & Climate Justice through Community Action”. The theme incorporates the India led global mass movement: Mission Lifestyle for Environment (Mission LiFE) emphasizing individual and community action to protect and preserve the environment. Mission LiFE recognises that Indian culture and living traditions are inherently sustainable and it seeks to explore the ways in which collective community action can help in realizing environmental sustainability and climate justice. The Colloquium's focus on community action and the integration o f traditional wisdom with modern environmental challenges makes it a significant and inspiring platform for driving positive change. The 2024 Colloquium's theme aligns with the urgent need to address environmental issues through collective action. The pres entations during the Colloquium will be organised in sub - themes that elaborate the overarching theme
