🔆India's Economic Growth🔆
✅Vision India@2047 is a project initiated by the NITI Aayog, to create a blueprint for India’s development in the next 25 years.
✅Objective: Achieving a USD 30 trillion economy with a per-capita income of USD 18,000-20,000 and strong public finances and a robust financial sector
International Monetary Fund (IMF) projections:
✅India is currently the fifth largest economy in the world in U.S. dollar terms
✅It projects that India will be the third-largest economy by 2027.
✅India has registered the highest growth rate amongst G20 countries, surpassing China’s for two successive years.
✅IMF’s historical data shows that India took six decades (1947 to 2007) to cross the one trillion-dollar GDP mark in 2007 ($1.2 trillion).
India’s problem of middle income trap:
✅India has been unable to leverage surplus labor to grow in low-end sectors.
✅The IT boom gave us an alternative pathway to growth, but the headroom there is limited.

🔆Water Pollution🔆
As per NITI Aayog, overall, 70 percent of the freshwater sources in the country were found to be contaminated and India ranks 120 out of 122 countries in terms of water quality.
Causes of Water Pollution :
✅ Water pollutants come from either point sources or dispersed sources. A point source is a pipe or channel, such as those used for discharge from an industrial facility or a city sewerage system.
✅A dispersed (or nonpoint) source is a very broad unconfined area from which a variety of pollutants enter the water body, such as the runoff from an agricultural area.
🔸 Domestic Sewage
🔸 Solid waste
🔸 Toxic waste
✅Impacts of Water Pollution: Destruction of biodiversity. Water pollution depletes aquatic ecosystems and triggers unbridled proliferation of phytoplankton in lakes — eutrophication. Contamination of the food chain
Initiatives to Control Water Pollution:
National Measures:
✅ Legal Measures: Water (Prevention & Control of Pollution) Act of 1974 and the Environment (Protection) Act of 1986. Preparation of action plan for sewage management and restoration of water quality in aquatic resources by State Governments
✅ Financial assistance for installation of Common Effluent Treatment Plants for cluster of Small Scale Industrial units
✅ Issuance of directions for implementation of Zero Liquid Discharge
✅ Implementation of National Lake Conservation Plan (NLCP) and National Wetland Conservation Programme (NWCP)for conservation and management of identified lakes and wetlands
International efforts:
✅ The Convention on the Protection and Use of Transboundary Watercourses and International Lakes (Water Convention) is a unique international legal instrument which aims to ensure the sustainable use of transboundary water resources
✅ The Protocol on Water and Health, jointly serviced by UNECE and WHO-Europe, is a unique legally binding instrument aiming to protect human health by better water management and by reducing water-related diseases.
✅SDG-6: By 2030, achieve universal and equitable access to safe and affordable drinking water for all.
