William Davison is Emeritus Professor of Environmental Chemistry at Lancaster Environment Centre, Lancaster University, UK, where he has previously served as Head of Department. His studies, complemented by research in environmental analytical chemistry, focus on the biogeochemistry of carbon, iron, manganese, sulphur and trace metals in natural waters. Professor Davison, with his colleague Hao Zhang, developed the techniques of diffusive equilibration in thin-films (DET) and diffusive gradients in thin-films (DGT) and pioneered their initial applications in waters, soils and sediments. He has contributed to over 250 publications, and the applications of his work have been recognised by the Pollution Abatement Technology Awards and the RSC Sustainable Water Award.
The Colorado River is an essential resource for a surprisingly large part of the United States, and every gallon that flows down it is owned or claimed by someone. David Owen traces all that water from the Colorado’s headwaters to its parched terminus, once a verdant wetland but now a million-acre desert. He takes readers on an adventure downriver, along a labyrinth of waterways, reservoirs, power plants, farms, fracking sites, ghost towns, and RV parks, to the spot near the U.S.–Mexico border where the river runs dry.
Water problems in the western United States can seem tantalizingly easy to solve: just turn off the fountains at the Bellagio, stop selling hay to China, ban golf, cut down the almond trees, and kill all the lawyers. But a closer look reveals a vast man-made ecosystem that is far more complex and more interesting than the headlines let on.
The story Owen tells in Where the Water Goes is crucial to our future: how a patchwork of engineering marvels, byzantine legal agreements, aging infrastructure, and neighborly cooperation enables life to flourish in the desert —and the disastrous consequences we face when any part of this tenuous system fails.
To grow produce of the highest nutritional quality the essential minerals lacking in our soil must be replaced, but this re-mineralization calls for far more attention to detail than the simple addition of composted manure or NPK fertilizers. The Intelligent Gardener demystifies the process while simultaneously debunking much of the false and misleading information perpetuated by both the conventional and organic agricultural movements. In doing so, it conclusively establishes the link between healthy soil, healthy food, and healthy people.
This practical step-by-step guide and the accompanying customizable web-based spreadsheets go beyond organic and are essential tools for any serious gardener who cares about the quality of the produce they grow.
