India faces a paradox: abundant annual rainfall (4,000 billion cubic metres) but significant water scarcity due to inefficient capture, storage, and use. The country's water crisis is institutional, not just hydrological, with per-capita water availability declining from over 5,000 to 1,400 cubic metres annually. India is the world's largest groundwater user, accounting for a quarter of global extraction. Governance involves a complex multi-level structure with Union, State, and local bodies. Initiatives like Jal Jeevan Mission, Atal Bhujal Yojana, and Pradhan Mantri Krishi Sinchayee Yojana aim to improve water supply, groundwater management, and irrigation efficiency, moving towards a circular water economy.
- India's water crisis is primarily institutional, stemming from inefficient water capture, storage, and use, despite high annual rainfall.
- Per-capita water availability has significantly declined from over 5,000 to 1,400 cubic metres annually.
- India is the world's largest groundwater user, responsible for roughly a quarter of global extraction.
Human-wildlife conflict (HWC) is a complex socio-ecological challenge driven by land use, livelihoods, and ecological change, rather than just a conservation problem. Interactions between humans and wildlife are intensifying due to rapid transformation of natural habitats, leading to animals adapting to agricultural or peri-urban areas. Crop raiding and livestock predation are adaptive responses to ecological constraints, not aggression. Global examples like Botswana and Finland show that community-based management, economic incentives, and ecological data are crucial for successful coexistence. India needs to strengthen compensation, improve ecological planning, and involve communities to manage HWC effectively and sustainably.
- Human-wildlife conflict (HWC) is a complex socio-ecological challenge, not merely a conservation issue.
- HWC is intensified by human activities transforming natural habitats, forcing wildlife to adapt to human-dominated landscapes.

The article highlights noise pollution as a pervasive and often tolerated issue in India, particularly in Tamil Nadu, exacerbated by events like cricket matches and political celebrations using pea whistles. Such noise levels (104-116 decibels) far exceed the safe threshold (85 decibels) and can cause hearing damage. Despite the Noise Pollution (Regulation and Control) Rules 2000, enforcement remains weak, partly due to political reluctance to police noise from festive occasions. The World Health Organization links significant disabling hearing loss to occupational noise and ranks noise as a major environmental cause of disability-adjusted life years lost in Europe. The author calls for political will to enforce existing rules and promote a culture of public sound that respects peace and health.

The term 'ecocide' refers to widespread, severe environmental damage, often caused by human actions during conflict, as seen in recent accusations against Israel regarding West Asia. Environmental groups advocate for its inclusion as an international crime under the Rome Statute, which currently classifies serious environmental damage as a 'war crime' only during war. Unlike existing anthropocentric laws, 'ecocide' would focus on harm to the environment as a separate entity. Challenges for its inclusion include achieving a 2/3rds majority vote from State Parties to the Rome Statute and issues of jurisdiction, as many nations, including Iran and Lebanon, are not ICC State Parties.
- 'Ecocide' denotes widespread and severe environmental damage, often linked to conflict.
- The term was coined in 1970 and first codified in Vietnam's domestic law in 1990.
- Current international laws, like the Rome Statute and Geneva Conventions, address environmental damage but are anthropocentric, focusing on harm to humans.
