A New Book On Drought by NASA GISS’s Ben Cook

Drought: An Interdisciplinary Perspective by Benjamin (Ben) Cook is the book you’ve always needed handy when the dry side of climate or climate change comes up in conversation.

The relationship between rainfall, groundwater, evaporation and transpiration, vegetation, bodies of water, animal distribution, agriculture, humans, and atmospheric conditions (not to mention oceanic factors and topography) underlie many different realms of academia and policy. Almost nothing I’ve ever done in my anthropological research didn’t include the hydrologic cycle, climate, and related issues. The weather weirding we are currently watching across the globe, including the current heavy rains and tornadoes, are part of this, and the long lived California Drought, the one that ended just recently, is as well.

In Drought: An Interdisciplinary Perspective, Cook looks at the dry end of the spectrum of the hydrologic cycle, but in so doing, he really has to cover the basics of rain related climate. There is math, and there is complicated science, in this book, but all of the material presented here is accessible to anyone who wishes to learn. If you are interested in climate change or agriculture, or paleoclimate, or any of that, Cook’s book is an essential reference, filling a gap that exists in the available range of current public-facing serious science books.

Cook covers the hydrologic cycle and the relationship between the hydrologic cycle and climatology. He defines the sometimes confusing concepts and measurements known as “drought” in a non-confusing and detailed way. I’ve found that in many discussions of drought, self defined experts who also happen to be climate change deniers tend to talk past (or over or around) others, making it difficult for the average non-expert to avoid frustration. Cook will arm you with the knowledge to stand up to such shenanigans!

Cook covers drought in the Holocene, and the relationship between climate change and drought. He provides two key detailed case studies (the American dust bowl, and droughts in the Sahel of Africa). He covers landscape degradation and desertification, and irrigation.

Drought: An Interdisciplinary Perspective is fully authoritative and thorough, and, as noted, very readable and understandable. Reading this book might make you thirsty but it will also make you smarter.

Ben Cook is a research scientist at NASA-Goddard Institute for Space Studies and the Lamont-Doherty Earth Observatory of Columbia University, and he teaches at Columbia’s School of Professional Studies.
