The birds, animals, insects, trees and plants encountered by the majority of the worlds people are those that survive in, adapt to, or are introduced to, urban areas. Some of these organisms give great pleasure; others invade, colonise and occupy neglected and hidden areas such as derelict land and sewers. Urban areas have a high biodiversity and nature within cities provides many ecosystem services including cooling the urban area, reducing urban flood risk, filtering pollutants, supplying food, and providing accessible recreation. Yet, protecting urban nature faces competition from other urban land uses.The Handbook of Urban Ecology analyses this biodiversity and complexity and provides the science to guide policy and management to make cities more attractive, more enjoyable, and better for our own health and that of the planet. This Handbook contains 50 interdisciplinary contributions from leading academics and practitioners from across the world to provide an in-depth coverage of the main elements of practical urban ecology. It is divided into six parts, dealing with the philosophies, concepts and history of urban ecology; followed by consideration of the biophysical character of the urban environment and the diverse habitats found within it. It then examines human relationships with urban nature, the health, economic and environmental benefits of urban ecology before discussing the methods used in urban ecology and ways of putting the science into practice.The Handbook offers a state-of the art guide to the science, practice and value of urban ecology. The engaging contributions provide students and practitioners with the wealth of interdisciplinary information needed to manage the biota and green landscapes in urban areas.

With compassion and an unswerving regard for the truth, veteran journalist Mark Seal lays bare the deeply moving, inspirational story of Joan Root, a dedicated environmentalist and Oscar-nominated wildlife filmmaker. He covers her early days in Kenya as a shy young woman with an almost uncanny ability to connect to animals; her whirlwind courtship with the dashing Alan Root, their marriage, and the twenty years of nonstop adventure and passionate romance that followed, both in Africa and around the world; the shattering disintegration of the marriage and partnership; and Joans triumphant struggle to reinvent herself as the protector of her lakeshore communitys fragile ecosystema struggle that would lead to her tragic death in January 2006. Joan Root dreamed of a bright future for Kenya, a country blessed with unmatched beauty but scarred by decades of colonization and a culture of corruption. She spent her life fighting to make that dream a reality. Her life ended too soon, but thanks to Seals meticulous re-creation, her extraordinary life lives on. (People, four-star review)

Nork esan behar zigun, herri honetan gertatu diren guztiak gertatuta, azkenean hondakinak izango zirela herrialde honetako eztabaidagai nagusia?. eajko bozeramaile baten hitz horiek hiritar askoren buruan ibili dira azkenaldian. Baina gaur egun Gipuzkoan hondakinen inguruan dagoen gatazkak erro sakonak ditu; izan ere, 2002an Gipuzkoan errauste plantak egiteko lerratu ziren interes politiko eta ekonomikoekin herritarrek izan duten talka dago egoeraren oinarrian. Alegia, errauste plantak eraiki behar zirela erabaki zuenak ez zuen pentsatuko hondakinak gutxitu, berrerabili, konpostatu eta birziklatzeko mugimendu bat sortuko zela Gipuzkoan, zero zabor mugimendua. Gatazka honen gaineko begirada pribilegiatua izan du Iñaki Petxarromanek, kazetari gisa hasiera-hasieratik jarraitu baititu errauste plantak egiteko proiek- tuen gaineko gorabehera guztiak, lehen eskutik jasotako informazioarekin sarri. Orain, informazio hori antolatu eta irakurlearen esku utzi du errealitatea ulertzeko gako guztiak izan ditzan.

Nowhere on Earth is the challenge for ecological understanding greater, and yet more urgent, than in those parts of the globe where human activity is most intense - cities. People need to understand how cities work as ecological systems so they can take control of the vital links between human actions and environmental quality, and work for an ecologically and economically sustainable future. An ecosystem approach integrates biological, physical and social factors and embraces historical and geographical dimensions, providing our best hope for coping with the complexity of cities.This book is a first of its kind effort to bring together leaders in the biological, physical and social dimensions of urban ecosystem research with leading education researchers, administrators and practitioners, to show how an understanding of urban ecosystems is vital for urban dwellers to grasp the fundamentals of ecological and environmental science, and to understand their own environment.
