Based on principles of the conservation and optimization of biodiversity and of equity and sustainability, this book focuses on the ecology of the coffee agroecosystem as a model for a sustainable agricultural ecosystem. It draws on the authors' own research conducted over the last twenty years as well as incorporating the vast literature that has been generated on coffee agroecosystems from around the world. The book uses an integrated approach that weaves together various lines of research to understand the ecology of a very diverse tropical agroforestry system. Key concepts explored include biodiversity patterns, metapopulation dynamics and ecological networks. These are all set in a socioeconomic and political framework which relates them to the realities of farmers' livelihoods. The authors provide a novel synthesis that will generate new understanding and can be applied to other examples of sustainable agriculture and food production. This synthesis also explains the ecosystem services provided by the approach, including the economic, fair trade and political aspects surrounding this all-important global commodity.

A unique anthology of poems--from around the world and through the ages--that celebrate trees. For thousands of years humans have variously worshipped trees, made use of them, admired them, and destroyed them--and poets have long chronicled the relationship. Poets from Homer and Virgil to Wordsworth, Whitman, and Thoreau, from Su Tung P'o and Basho to Czeslaw Milosz and W. S. Merwin have celebrated sacred groves, wild woodlands, and bountiful orchards, and the results include some of our most beloved poems. Robert Frost's "Birches," Marianne Moore's "The Camperdown Elm," Gerard Manley Hopkins's "Binsey Poplars," and Zbigniew Herbert's "Sequoia" stand tall beside Eugenio Montale's "The Lemon Trees," Yves Bonnefoy's "The Apples," Bertolt Brecht's "The Plum Tree," D. H. Lawrence's "The Almond Tree," and A. E. Housman's "Loveliest of Trees." Whether showing their subjects being planted or felled, cherished or lamented, towering in forests or flowering in backyards, the poems collected here pay lyrical tribute to these majestic beings with whom we share the earth.

Inspired by the creation of Arbor Day, this gentle picture book illuminates the experience of establishing roots in a new home and the comfort that a familiar landscape can provide. Katie and her papa are among a group of settlers building a town in the middle of the dusty, brown prairie. Every week the trains bring more people who build houses, fences, and barns. But one thing is missing: trees. The townspeople take up a collection to order trees from back east and Katie adds her own pennies and Papa's silver dollar. When the tiny saplings finally arrive, Katie helps dig holes and fetch water. Then, in a quiet corner off the public square, Katie and Papa plant a flowering dogwood in memory of Mama. Kathryn O. Galbraith's gentle story of community building, the timelessness of love, and the power of ritual will resonate with readers.
