The Algal Bowl: Overfertilization of the World's Freshwaters and Estuaries

The greatest threat to water quality worldwide is nutrient pollution. Cultural eutrophication by nutrients in sewage, fertilizers, and detergents is feeding massive algal blooms, choking out aquatic life and outpacing heavy metals, oil spills, and other toxins in the devastation wrought upon the world's fresh waters. Renowned water scientists, David W. Schindler and John R. Vallentyne, share their combined 80 years of experience with the eutrophication problem to explain its history and science, and offer real-world solutions for mitigating this catastrophe in the making. For those who have lost sight of Vallentyne's 1974 first edition, Schindler's fully revised and expanded edition is an unambiguous road map for change.

My second time reading this book, I still think it's a bit of a mishmash, but that's okay, because readers can simply pick and choose sections they're interested in and don't have to read the book as a whole in order to learn from it. The sections discussing remediation of eutrophication are great - anyone who has a hand in managing lakes and their watersheds should read them.

Great background and overview of a massive challenge to our freshwaters and estuaries. I read this as background for my own research and am really glad I found it. Wonderful thorough history.

The writing has its poetic moments describing lake biology, which is a good thing in a academic book. In fact, the authors do a lot of word-chiseling to convey the beauty of the reactions and the processes happening in the water.

*****************
L’intrigue repose sur le « bol d’algues » qui envahit nos lacs, un meurtre silencieux, dont seules les éclosions d’algues, les cyanobactéries, nous avertissent! Les auteurs nous expliquent, les facteur de l’euthrophisation des lacs, dont le facteur humain.

C’est un livres très académique et très pointu, dans mon domaine d’études. Avec des cartes, des données, des mesures, des statistiques. D'ou mon pointage plus bas pour le public, mais ce serait 4 sur 5 pour moi.


L’étude de cas de deux lacs de Madison (Monona et Mendota) illustre l’impact du défrichages et de la culture avec engrais sur la faune et la flore du lac. L’étude de l’évolution du lac Winnipeg, qui recrache des mousses toxiques de cyanbactérie sur ses rives…

Résumé de l’intrigue: on relache de la chnoute, beaucoup de chnoute (matière fécale, engrais azoté, donc matière organique) dans un lac. La chnoute, pour se décomposer, absorbe l’oxygène dissous dans l’eau. Que les poissons, eux, n’ont plus à leur disposition, donc ils meurent, couic. D’autres organismes prennent leur place et modifient les écosystèmes aquatiques.

Et c’est publié par les presses de l’université de Calgary. Des Albertains écologistes sérieux, ca existe.
