Why is the world today confronted with a crisis of availability of and access to freshwater resources?
Approach · directive: “why”
What it asks · Explain both sides of the crisis, physical availability of freshwater and unequal access to it, and why each is worsening.
It asks 2 things — answer each
- Explain why: the physical availability of usable freshwater is shrinking relative to need (supply, demand, over-extraction, pollution, climate change)
- Explain why: access to freshwater is unequal, and how scarcity and unequal access reinforce each other, with a way forward
Open with · In 2022 roughly half the world's population faced severe water scarcity for part of the year and 2.2 billion people lacked safely managed drinking water; the crisis is one of quantity and of distribution.
Cover
- Finite, uneven supply: usable freshwater is a small share of all water and varies by region and season.
- Farm-heavy demand: agriculture takes 72% of freshwater withdrawals (UN WWDR 2024); cities and industry add more.
- Over-extraction and pollution: aquifers pumped faster than recharge; sewage and chemicals spoil what remains.
- Climate change: shifting rain, glacier melt, saline intrusion; droughts affected 1.4 billion people in 2002–2021.
- Access: poor infrastructure and poverty; women and girls bear the collection burden; under-pricing and leaky pipes.
- Shared basins: 153 Member States share transboundary waters, yet cooperation arrangements lag.
- Way forward: demand management, reuse, recharge, fair tariffs and basin cooperation.
Close with · At the current pace, 2 billion people will still lack safely managed drinking water in 2030, the SDG 6 target year; the gap is one of governance more than hydrology.

Model answer· 223words · Minimalist IAS
In 2022, roughly half the world's population faced severe water scarcity for part of the year, and 2.2 billion lacked safely managed drinking water (UN). The crisis is one of quantity and of reach.
Why availability is shrinking
- Finite, uneven supply: usable freshwater is a small share of all water, unevenly spread across regions and seasons.
- Farm-heavy demand: agriculture takes 72% of freshwater withdrawals (UN WWDR 2024), while cities and industry add more.
- Over-extraction and pollution: aquifers are pumped faster than they recharge; sewage, effluents and agrochemicals spoil the rest.
- Climate change: shifting rainfall, glacier melt and saline intrusion disturb supply; droughts hit 1.4 billion people in 2002–2021.
- Over-pumping, pollution
- Less usable water
- Poor priced out
- Unequal access
Why access is unequal
- Infrastructure and poverty: the poor rely on distant or unsafe sources; women and girls bear the collection burden.
- Pricing and governance: under-priced water is wasted by the well-off and lost in leaky pipes; the poor buy from tankers.
- Shared basins: 153 UN Member States share transboundary waters, yet cooperation lags, turning scarcity into tension.
Way forward
- Manage demand and supply: micro-irrigation, wastewater reuse, aquifer recharge, fair tariffs and basin-wide cooperation agreements.
At the current pace, 2 billion people will still lack safely managed drinking water in 2030, the SDG 6 target year; the gap is one of governance more than hydrology.
