Revision summary
Usable freshwater is a small and uneven share of global water. Farms, falling groundwater, climate shifts, and pollution cut availability. Poverty, tanker markets, and transboundary politics cut access. Virtual water in trade moves scarcity from one region to another. SDG 6 will fail unless drinking rights, irrigation reform, and clean rivers are treated as one task.

Conclusion
- Price irrigation and urban water so waste falls, while protecting a basic drinking quota for the poor.
- Recharge aquifers, reuse treated wastewater, and share basin data across borders.
- Treat sanitation and pollution control as part of freshwater policy, not as a later add-on.
Freshwater is in crisis because nature’s supply is uneven and because farms, cities, and politics waste or lock what remains. Availability and access must be fixed together through conservation, fair pricing, and clean supply.

Why separate availability from access?
A full aquifer does not help a slum without a tap. A pipe does not help if the river is poisoned or dry.

Explain the role of geographical factors towards the development of Ancient India.
World's Physical Geography
Harappan cities grew on the Indus system and later states on the Ganga plains because alluvium and monsoon rain supported surplus. The Himalaya, Ghats, and Deccan split cores of settlement and directed routes. Passes in the north-west and ports on both seas linked India to Central Asia, Rome, and South-East Asia. Copper, iron, and gold supplied tools and craft. Geography set the stage; it did not replace human institutions.

What was the difference between Mahatma Gandhi and Rabindranath Tagore in their approach towards education and nationalism?
The Freedom Struggle
Gandhi’s Wardha scheme of 1937 put mother tongue, craft, and character at the centre of schooling. Tagore’s Santiniketan and Visva-Bharati put nature, art, and world learning at the centre. Gandhi’s nationalism was mass satyagraha and village swaraj. Tagore’s nationalism was freedom without the cult of the nation. Both opposed colonial rule; they split on industrial civilisation and on how open India should stay.

Bring out the socio-economic effects of the introduction of railways in different countries of the world.
World's Physical Geography
Britain used railways to move coal and factory goods and to urbanise the industrial north. The United States used a transcontinental line to make a continental market and to settle the west. Japan and Russia used state-backed trunk lines for catch-up and empire. Colonial India and Africa often saw lines that moved export cargo and troops, with mixed social gains. Everywhere, railways changed time, travel, and the idea of a national space.
