Biological anthropologist Helen Fisher, renowned for her research on the science of love, joins to explore the emotional intricacies of romance. The discussion shifts to the critical issue of global water scarcity, emphasizing the importance of pricing water to promote sustainability. Fisher shares insights from her MRI studies on love, revealing how romantic feelings activate the brain. The urgent challenges of water management in places like Chile are highlighted, showcasing a need for innovative solutions in the face of climate change.
Water pricing can incentivize conservation and efficient use, as demonstrated by successful water trading practices in Australia.

Water Stress in Chile
Chile faces a significant water crisis as prolonged droughts have led to increasingly severe water shortages, affecting both rural farmers and urban areas like Santiago. Alejandro Meneses, a vegetable farmer, highlighted that not only is there insufficient water for agriculture, but water theft has exacerbated the issue, leading to rising food prices and potential social unrest. The Minister for Public Works, Jessica Lopez, warned that while Santiago's water supply remains stable for now, projections indicate it may become inadequate within a decade. Chile's experiences mirror a broader global challenge, with approximately half of the world's population enduring periods of high water stress annually, necessitating urgent solutions.
Global Water Scarcity Trends
The increase in flooding and droughts worldwide affects a staggering number of people, with climate change predicted to worsen the frequency and intensity of these events. By the century's end, freshwater availability per person is expected to decline by 29%, with Africa facing the most drastic reductions of up to two-thirds. This situation is likely to induce significant migration patterns as individuals move from water-scarce regions to areas with abundant resources. In the face of varied water availability globally, the need for innovative technology and new political frameworks to manage water resources becomes essential.
Economic Solutions for Water Management
Effective water management often hinges on establishing a price for water, which incentivizes conservation and efficient use. Successful examples, such as Australia, show that allowing water trading can lead to better allocation and conservation practices among farmers. However, political resistance, especially from conservative groups fearing adverse impacts on farmers, makes the implementation of such systems challenging. Without a willingness to put a price on water, the looming water crisis may escalate, ultimately forcing governments and societies to confront the issue more aggressively in the future.
Water scarcity is growing even in parts of the world that used to be drought-free. Since most countries waste vast quantities of water, charging for it would help.
