Launching the PPIC Water Policy Center ten years ago was a risk. How was a small team going to have a big impact on such intractable problems? After a decade, the proof is in the pudding. We’ve done it by being interdisciplinary, seeking out facts amid controversy, and really trying to understand the challenges and opportunities in each water sector. Despite the many difficulties and complexities of California’s water, the state has made tremendous progress on water management in the last decade, and the Water Policy Center has worked hard to support that progress with forward-looking, nonpartisan research. We follow where the facts lead, and that commitment to the facts—even if the results are not popular—has made us a trusted voice on some of the thorniest challenges in the field. Since the center launched ten years ago, we’ve released a wide range of impactful research. Here are just four major areas of research we’ve conducted on issues that matter deeply to all Californians.
