A thoughtful exploration of how the Sahara Desert can be returned to its former glory as a green paradise while actively combating climate change. A green Sahara is something the world has not seen since 10,000 BC when the Sahara was a wet, lush region. Grasslands, woodlands, tropical forests, and wetlands, the natural plant bounty of the ancient Sahara, provided residents with enormous flocks of birds, fish in abundance, indigenous grains and herds of wild game. By 3,000 BC though the climate changed, the rains stopped, and the ancient green Sahara dried into today’s desert. It had been the victim of a phenomenon that reminds us today of global climate warming, a tragedy that we have unwittingly brought upon ourselves. But what if we could reverse the desertification of the Sahara, and bring back the green paradise of days passed? In The Green Sahara: Reclaiming Paradise in the Face of Climate Change, John Gaudet explores the process by which climate change in ancient times converted a green paradise into an arid desert land, highlighting parallels to what is happening in our time. But he also illuminates how an intense effort to create green energy is being made by several Saharan countries to build and operate enormous solar and wind farms. As a result, a wave of green energy generated in the Sahara, the largest desert on earth, is about to swamp the world, and could lead to a regreening of the Sahara Desert. If a new green Sahara happens, how will the world benefit? Covering just 20% of the Sahara Desert with wind turbines and solar panels would generate almost five times more energy than is currently needed worldwide. Gaudet highlights further benefits of regreening the Sahara by deploying climate technology to the desert such as sequestering large amounts of carbon from the atmosphere and eliminating negative health and ecosystem effects felt worldwide from desert dust. Gaudet’s manifesto demonstrates how, in this fascinating case, climate change induced by man actually has the power to save the world and restore a beautiful piece of ancient history.
John Gaudet’s The Green Sahara is an entertaining and enlightening account of the Sahara as it went from a vast, verdant home to magnificent flora and fauna and human civilizations to the largest desert in the world, and of how innovative individuals not only coped with the Sahara’s desertification but came up with ideas to regreen it. Nearly every chapter tells of surprising discoveries, including how the green Sahara and its people affected Egyptian civilization and mythology, how the Sahara desert’s dust storms affect weather, people’s health, and agricultural productivity in the America’s, and how lessons gained from coping with desertification have world-wide relevance in dealing with the challenges of climatic changes. -- Michael McGahuey, former natural resources management specialist, USAID, CARE (Chad) and the US Peace Corps (Niger) John Gaudet's The Green Sahara is what everyone working to solve the problem of climate change—from climate advocates to researchers to policy makers—needs right now: an optimistic inquiry into a potential solution, grounded in a data-backed, actionable vision and a genuine love for the people, places, and ecologies at stake. Gaudet's enthusiasm for the Sahara, and the possibility of making it green once again, shines through on every page, making his well-researched offering an easy and enjoyable read. -- Rebecca Pryor, executive director, Guardians of Flushing Bay The African continent has a unique place in human history. Gaudet shows here how it could also play an integral part in our future. The Green Sahara, released posthumously, provides a valuable insight into the management and conservation of aquatic resources, particularly in the context of human-induced changes and today’s environmental challenges. It is a must-read for anyone interested in the impact of climate change and how, even now, we could still make a difference. -- Dean Allen, PhD, author and historian John Gaudet’s The Green Sahara is a revelation. Instead of viewing the Sahara as forever desolate and forbidding, Gaudet inspires us to appreciate it as a source of hope for a greener future for all of us. Gaudet helped me learn that the Sahara can become green once again, not so much from huge infrastructure investments that have often failed, but from the people who actually live in the region—the innovators and adapters who know their land best and have already made impressive gains. -- Andrew Sisson, professor of the practice, University of North Carolina at Chapel Hill
