Global Droughts: A Bad Year

Populations around the world face many severe water challenges, from scarcity to contamination, from political or violent conflict to economic disruption. As populations and economies grow, peak water pressures on existing renewable water resources also tend to grow up to the point that natural scarcity begins to constrain the options of water planners and managers.…

As readers of this column may already know, earlier this week the Pacific Institute and I announced an important and exciting change: on July 1st after 28 years as co-founder and President of the Institute, I will be moving to a new position as President Emeritus and Chief Scientist. A wide search for a new president…

By Peter Gleick, Brett Walton, J. Carl Ganter Water was a Top Risk on the 2015 Global Agenda In early 2015, participants at the World Economic Forum, a who’s who of the political and business elite, ranked water crises as the top global risk. Water was also a key factor in the adoption by the…

On December 9th, National Public Radio broadcast an interview between NPR’s Steve Inskeep and Senator Ted Cruz on the subject of climate change. Below is an annotated transcript of that interview with my [bracketed] responses to the consistently false scientific claims made by Senator Cruz. Effectively, every single scientific point he made was wrong –…

Breaking Water Taboos

The recent severe drought in the Western United States — and California in particular — has shined a spotlight on a range of water-management practices that are outdated, unsustainable, or inappropriate for a modern 21st century water system. Unless these bad practices are fixed, no amount of rain will be enough to set things right.…

  If there is anything that the past few decades of research and study of major global challenges tells us, it is that truly effective solutions to sustainability challenges require truly integrated approaches across disciplines, fields of study, data sets, and institutions. We are not going to solve 21st century global problems with 20th century…

By Peter Gleick (Pacific Institute) and Carl Ganter (Circle of Blue) 1. The California Drought Becomes an Emergency California’s multi-year drought grew dire enough in 2014 to prompt Governor Jerry Brown to declare a drought emergency in January. By the end of the year, California had experienced the driest and hottest 36 months in its 119-year…

Over the past three years (and indeed, for 10 of the past 14 years) California has experienced a particularly deep drought. How bad is the drought? Is it the worst in the instrumental record? The worst in over a century? The worst in 1200 years? The worst “ever”? And why has it been so bad?…

In a new study just published by the journal Sustainability Science (Springer), analysis from the Pacific Institute (with lead author Dr. Juliet Christian-Smith, now at the Union of Concerned Scientists) shows that many of the fundamental responses of California water users to severe drought actually make the state’s overall water conditions worse – that in the end,…

The Death of the Aral Sea

In the 20th century, society was either ignorant of, or ignored, the consequences of bad water management. The goal was economic development at all costs. Over the past few decades, we’ve learned about the ecological and social implications of the misuse of water, and some efforts have been made to protect natural ecosystems, restore a modicum…
