Mangroves are crucial for anchoring coastal economies, protecting against climate extremes, and providing billions in ecosystem services, yet their value is often overlooked in policy. The article advocates for recognizing mangroves as active drivers of sustainable growth and security through three pillars: mapping with technology, involving communities, and using platforms. Advanced geospatial AI and drone data can quantify mangrove value, informing restoration efforts. Community-led conservation, leveraging local knowledge, and creating alternative livelihoods like aquaculture and eco-tourism are essential. Engagement platforms like 'Mangrove Mitras' can foster urban citizen and local community involvement, rebuilding the human-wetland-river-mangrove connection.
- Mangroves are critical for coastal protection, climate resilience, and supporting livelihoods, providing significant ecosystem services.
- Their economic and ecological value, including carbon sequestration, is often underestimated in policy frameworks.

The article argues that the India-U.K. Free Trade Agreement (FTA) has made significant compromises in India's digital sector, impacting its digital sovereignty. Key concessions include giving up India's right to ex ante access to source code for foreign digital goods and services, and granting U.K. parties access to 'Open Government Data,' which is now considered a valuable national resource. These moves contradict India's long-held positions at global forums like the WTO and risk eroding India's competitive advantage in AI and national security. The authors emphasize the urgent need for a comprehensive digital sovereignty and industrialization policy to guide trade negotiations and safeguard India's digital future.
- The India-U.K. FTA compromises India's digital sovereignty by conceding regulatory rights over source code and access to national data.
- India has given up its right to ex ante access to source code for foreign digital goods, a reversal of its previous stance.
- Granting equal access to 'Open Government Data' to U.K. parties is seen as a major giveaway, as data is a critical resource for AI and national security.
India aims to eliminate malaria by 2030, a goal complicated by hidden reservoirs, remote geographies, and parasite resistance. Despite an over 80% reduction in malaria burden between 2015-2023, tribal districts still show high rates.

The article highlights that human activities such as mining, groundwater extraction, impounding water behind dams, and injecting fluids into the ground can induce seismic activity, leading to human-induced earthquakes. These activities cause strain accumulation between tectonic plates. A 2021 study linked shallow earthquakes in the National Capital Region to excessive groundwater extraction. Large dams, like the Koyna hydroelectric dam, have also been associated with significant earthquakes. India's growing energy demand, met through hydropower and oil/gas extraction (including fracking), further increases this risk. Scientists emphasize the need for scientific management of groundwater, proper evaluation before dam construction, and strong seismic networks to monitor these activities.
- Human activities like groundwater extraction, dam construction, and energy extraction can induce earthquakes.
- These activities alter the stress regime in the Earth's crust, leading to seismic events.
- Examples include earthquakes linked to groundwater depletion in Delhi-NCR and the Koyna dam.
