Urbanization is a global phenomenon and the book emphasizes that this is not just a social-technological process. It is also a social-ecological process where cities are places for nature, and where cities also are dependent on, and have impacts on, the biosphere at different scales from local to global. The book is a global assessment and delivers four main conclusions: Urban areas are expanding faster than urban populations. Half the increase in urban land across the world over the next 20 years will occur in Asia, with the most extensive change expected to take place in India and China Urban areas modify their local and regional climate through the urban heat island effect and by altering precipitation patterns, which together will have significant impacts on net primary production, ecosystem health, and biodiversity Urban expansion will heavily draw on natural resources, including water, on a global scale, and will often consume prime agricultural land, with knock-on effects on biodiversity and ecosystem services elsewhere Future urban expansion will often occur in areas where the capacity for formal governance is restricted, which will constrain the protection of biodiversity and management of ecosystem services
Set in the North Shore suburbs of Chicago, amid traffic, pollution, and ever-increasing neighborhoods of houses and apartments, these meditative personal essays explore the importance of our connection with the natural world, history, and memory. The Suburban Wild follows the seasons from one spring to the next, celebrating the natural miracles we frequently miss and revealing a territory less tamed than we might imagine. These essays offer the sights and sounds found on the outskirts of cities, just perceptible amid the clutter and din of crowded streets and sidewalks. From the constant humming of cicadas on summer evenings and the seasonal migrations of ducks to the myriad hues in a green heron's feathers, Peter Friederici reveals a complex place in which wild geese and morning commuters share the same habitat. The essays honor our lost creatures and places, emphasizing the importance of history, memory, and consciousness. The author describes the varying shades and textures of a clay bluff near his childhood home, relating the gradual erosion and recession of this Ice Age-old landform. A description of spirogyra algae blooms on Lake Michigan merges with a discussion of the lake's once abundant native mussels and the imported zebra mussels that are threatening their existence. From recorded memories, Friederici re-creates the sight of the now extinct passenger pigeon. Though awareness of the destruction of the landscape and its creatures is never far from the wonders presented here, The Suburban Wild connects the tracks of wildlife and traces of our changing landscape with our own path through the world. The book explores how history--whether natural or cultural, collective or personal--shapes a landscape, and how human memory shapes that history. At heart, it seeks to forge a link between the world outside our windows and the one inside.
Both a traveler's tale of a 359-mile canoe trip and an exploration of the dramatic environment of the Upper Midwest's Driftless region, following the streams of geologic and human history.
"In A Natural History of the Chicago Region, Greenberg takes you on a journey that begins with European explorers and settlers and hasn't ended yet. Along the way he introduces you to the physical forces that have shaped the area from southeastern Wisconsin to northern Indiana and Berrien County in Michigan; the various habitat types present in the region and how European settlement has affected them; and the insects, reptiles, amphibians, birds, fish, and mammals found in presettlement times, then amid the settlers and now amid the skyscrappers. In all, Greenberg chronicles the development of nineteen counties in Illinois, Michigan, and Wisconsin across centuries of ecological, technological, and social transformations."--BOOK JACKET.
