Global Water Crisis Threatens Half of World’s Food Production

Experts have warned that over half of the world’s food supply could collapse in the next 25 years, sending a severe warning to the rest of the world. This concerning forecast is based on a thorough report by the Global Commission on the Economics of Water, which emphasizes the growing water problem endangering the world’s agricultural systems.

The Growing Threat of Water Scarcity

The 194-page review paints a grim picture of the current state of global water resources. Already, half of the world’s population faces water shortages, a situation expected to worsen as climate change intensifies. Johan Rockström, director of the Potsdam Institute for Climate Impact Research and co-chair of the commission, emphasizes that “water is victim number one of the [climate crisis],” with water systems under “unprecedented stress.”

The report projects that by the end of this decade, demand for freshwater will exceed supply by a staggering 40%. This imbalance is exacerbated by rising global temperatures, with each 1°C increase adding 7% more moisture to the atmosphere, leading to more severe weather events and disrupting the hydrological cycle.

Impact on Global Food Security

The consequences of this water crisis on food security could be catastrophic. Scientists have observed that the 1.3°C warming above pre-industrial levels has already reduced crop yields in some regions. Current estimates suggest that over a billion people are facing rising food insecurity, with production potentially falling by 20% in some countries.

While the Global North may temporarily benefit from extended agricultural seasons due to warmer temperatures, the Global South faces the prospect of extreme temperatures and more frequent droughts, significantly impacting food production.

Underestimated Water Needs

The commission’s findings reveal a startling discrepancy between estimated and actual human water requirements. While 50-100 liters per person per day are considered necessary for basic health and hygiene, the report suggests that people need around 4,000 liters daily to ensure adequate nutrition and a dignified life. This level of water use is locally unattainable for most regions, highlighting the critical role of international trade in food, clothing, and consumer goods in meeting water needs.

The Role of ‘Green Water’ and Global Interdependence

The report introduces the concept of “green water” – soil moisture crucial for food production. Countries like China and Russia benefit from extensive river networks and air currents that transport moisture across regions. Meanwhile, nations such as India and Brazil are major exporters of green water, supporting moisture flows to other areas through their ecosystems.

This interconnectedness underscores the need to treat freshwater as a global common good. As Rockström points out, “The Chinese economy depends on sustainable forest management in Ukraine, Kazakhstan, and the Baltic region,” illustrating the complex web of global water dependencies.

Calls for Radical Water Management

Tharman Shanmugaratnam, president of Singapore and co-chair of the commission, urges nations to cooperate on managing water resources before the situation becomes untenable. The report calls for eliminating harmful subsidies, particularly the $700 billion annually allocated to agriculture, which often encourages wasteful water use.

The water crisis disproportionately affects women and developing nations. Mariana Mazzucato, a co-chair of the commission, highlights the need for international financial institutions to make water conservation a condition for loans to developing countries.

Conclusion

The report from the Global Commission on the Economics of Water is a wake-up call to the international community. Without coordinated global action to address the growing water crisis, the world will face a severe food and water emergency within the next twenty-five years. It’s time to radically rethink water management and conservation, as the future of global food security hangs in the balance.

Preparing the Battlefield: The Role of Water in War

Water has always been a strategic resource in the context of war, and its importance is only increasing as the world faces a growing global water crisis. From historical conflicts to modern military strategies, control over water can determine the outcome of entire wars. This critical element can be exploited in multiple ways, making it a key factor in both warfare preparation and execution.

Strategic Water Tactics in War:

1. Naval Blockade: Controlling access to water routes can isolate nations, cut off vital supplies, and cripple economies.
2. Water Scarcity: Targeting water infrastructure or natural sources can lead to devastating shortages, putting civilian populations and armies in dire straits.
3. Flooding and Dam Attacks: Destruction of dams or other water control systems can cause catastrophic flooding, leading to widespread damage and displacing large populations.

These strategies demonstrate how water is not just a resource, but a tool of war. Nations preparing for conflict often prioritize controlling water supplies as part of their broader military strategies.

As the global water crisis deepens, the role of water in both war and peace becomes ever more critical. Control over water resources not only influences the outcomes of wars but also holds the key to the future of global food production. This underscores the importance of proactive, cooperative water management strategies to ensure a secure future for all.
