#### The Last Drop: Solving the World's Water Crisis (2022) `Author:` Tim Smedley `Source:` https://www.timsmedleywriter.com/book-2-the-last-drop/ `Published:` 2026-01-16 > [!info] > An investigation into the global water crisis — shortages, excesses, and the solutions that might avert catastrophe. Smedley frames water stress as the next great climate crisis, examining everything from drying rivers and ancient lakes to desalination and nature-based approaches. >  ## Summary The Last Drop is environmental journalist Tim Smedley's investigation into the global freshwater crisis. Smedley argues that water stress — not just scarcity, but also pollution, overconsumption, and mismanagement — is already driving climate refugees and will soon become one of the defining challenges of our time. Rivers are drying before they reach the sea, ancient lakes are disappearing, and even rain-soaked countries like Britain are vulnerable. The book takes an unblinking look at how we arrived at this point and then turns to solutions: from technological approaches like desalination and atmospheric water harvesting, to radical proposals like towing icebergs, to nature-based strategies that work with ecosystems rather than against them. Smedley also explores the interconnected food-water-energy nexus and the role of harmful algal blooms in degrading freshwater systems. The book was named among Science News's best science books of 2024 and has been described as a "smouldering indictment of the self-inflicted wounds we're causing ourselves and Earth by careless exploitation of water." ## Key Takeaways 1. **Water Stress Is the Next Climate Crisis** — It's not just scarcity but the combination of increased demand, pollution, and mismanagement that makes water the defining environmental challenge ahead. Water stress is already driving displacement and climate refugees. 2. **No Country Is Immune** — Even rain-soaked Britain faces water insecurity. The UK averages 1200mm of annual rainfall, yet within months significant parts of the country face shortages. Abundance in winter does not guarantee security year-round. 3. **The Food-Water-Energy Nexus** — By 2030, the world will need 30% more water, 40% more energy, and 50% more food. These systems cannot be managed in isolation; water is needed for energy production, and energy is needed to pump, treat, and transport water. 4. **Pollution Is as Dangerous as Scarcity** — Harmful algal blooms (HABs), once mostly marine, are increasingly affecting freshwater systems. Nutrient runoff and industrial pollution render water unusable even when it's physically present. 5. **Technological Solutions Exist But Aren't Silver Bullets** — Desalination, atmospheric water harvesting (pulling moisture from air that holds an estimated 12,900 cubic km of water globally), and even iceberg towing are technically feasible. But energy costs and environmental trade-offs mean technology alone won't solve the crisis. 6. **Working With Nature Matters** — Smedley explores nature-based solutions alongside technological ones, suggesting that restoring ecosystems and changing how we manage water at its source may be more sustainable than engineering fixes alone. ## Quotes - "Drought is... the next pandemic." - "I am living on borrowed time and borrowed water." — Smedley on his own water consumption in Oxfordshire - "It is the smell of decay and death... when you put your paddle in it, you can feel it." — Beth Stauffer, University of Louisiana, on harmful algal blooms - "The Last Drop is a smouldering indictment of the self-inflicted wounds we're causing ourselves and Earth by careless exploitation of water." — Geographical magazine review ## Notes - The volume of freshwater that breaks off Antarctica as icebergs each year exceeds total global freshwater consumption — and that doesn't include Arctic ice. This has inspired proposals to tow icebergs to water-stressed regions. - The US alone uses 520 billion kWh to move, treat, and heat its water — a significant portion of national energy use. - The book was published by Picador in spring 2022 after publishing director Georgina Morley acquired world rights. `Concepts:` [[Water Scarcity]] [[Climate Crisis]] [[Ecology]] `Knowledge Base:` ## Related Articles and Reviews - [The Guardian Long Read: 'Drought is... the next pandemic'](https://www.theguardian.com/news/2023/jun/15/drought-is-on-the-verge-of-becoming-the-next-pandemic) - [Book review — The Times](https://www.thetimes.co.uk/article/the-last-drop-solving-the-worlds-water-crisis-by-tim-smedley-review-how-britains-taps-could-run-dry-wh2wjxm0t) - [Book review — Geographical](https://geographical.co.uk/book-reviews/review-the-last-drop-by-tim-smedley) - [Book review — The TLS](https://www.the-tls.co.uk/articles/the-last-drop-tim-smedley-book-review-erica-gies/) - [BBC Future: Is the world running out of fresh water?](http://www.bbc.com/future/story/20170412-is-the-world-running-out-of-fresh-water) - [BBC Future: Why Britain's rain can't sustain its thirst](http://www.bbc.com/future/story/20190310-why-britains-rain-cant-sustain-its-thirst) - [BBC Future: The outrageous plan to haul icebergs to Africa](http://www.bbc.com/future/story/20180918-the-outrageous-plan-to-haul-icebergs-to-africa) - [BBC Future: Pollution causing harmful algal blooms](https://www.bbc.com/future/article/20230110-the-pollution-causing-harmful-algal-blooms) - [The Guardian: The food, water and energy nexus](https://www.theguardian.com/sustainable-business/securing-a-sustainable-future) - [The Guardian: 'Energy for water' may have greater impact](https://www.theguardian.com/sustainable-business/energy-water-greater-impact-nexus) - [Science News: Best science books of 2024](https://www.sciencenews.org/article/best-science-books-of-2024) - [Alnwick Story Fest: Tim Smedley event](https://alnwickstoryfest.substack.com/p/the-last-drop-renowned-environment)
