Alrededor del mundo, la energía juega un papel fundamental para conseguir el desarrollo de toda sociedad. Forma parte, directa o indirectamente, de toda actividad económica. A lo largo de la historia, los seres humanos hemos aprendido a adaptar las diferentes fuentes de energía (el sol, el viento, el agua, los hidrocarburos, entre otras), provistas por la naturaleza para conseguir nuestros beneficios. Sin embargo, las desigualdades económicas existentes entre todos los países del mundo han imposibilitado el aprovechamiento de todas las fuentes energéticas en igual medida: los países de ingreso bajo se ven restringidos al acceso a tecnología de aprovechamiento energético debido a la cantidad de inversión que se requiere.
A manifesto for a radically different philosophy and practice of manufacture and environmentalism "Reduce, reuse, recycle" urge environmentalists; in other words, do more with less in order to minimize damage. But as this provocative, visionary book argues, this approach perpetuates a one-way, "cradle to grave" manufacturing model that dates to the Industrial Revolution and casts off as much as 90 percent of the materials it uses as waste, much of it toxic. Why not challenge the notion that human industry must inevitably damage the natural world? In fact, why not take nature itself as our model? A tree produces thousands of blossoms in order to create another tree, yet we do not consider its abundance wasteful but safe, beautiful, and highly effective; hence, "waste equals food" is the first principle the book sets forth. Products might be designed so that, after their useful life, they provide nourishment for something new-either as "biological nutrients" that safely re-enter the environment or as "technical nutrients" that circulate within closed-loop industrial cycles, without being "downcycled" into low-grade uses (as most "recyclables" now are). Elaborating their principles from experience (re)designing everything from carpeting to corporate campuses, William McDonough and Michael Braungart make an exciting and viable case for change.
This report shows that the high level of policy support contributes little to reduced greenhouse-gas emissions and other policy objectives, while it adds to a range of factors that raise international prices for food commodities.
Cities of Tomorrow is a critical history of planning in theory and practice in the twentieth century, as well as of the social and economic problems and opportunities that gave rise to it. Trenchant, perceptive, global in coverage, this book is an unrivalled account of its crucial subject. The third edition of Cities of Tomorrow is comprehensively revised to take account of abundant new literature published since its original appearance, and to view the 1990s in historical perspective. This is the definitive edition, reviewing the development of the modern planning movement over the entire span of the twentieth century.
This publication presents a set of energy indicators for sustainable development and is an analytical tool for countries to track their progress on energy for sustainable development.

The book is based on the exchange of professional experiences which featured in an IUCN CEC workshop in August 2002. Practitioners from around the world shared their models of good practice and explored the challenges involved in engaging people in sustainability. The difficulties facing practitioners vary between country and context but some challenges are universal: A lack of clarity in communicating what is meant by sustainable development; An ambition to educate everyone to bring about a global citizenship; Social, organisational or institutional factors constrain change to sustainable development, yet there is an emphasis on formal education, and community educators do not receive the same support; A lack of balance in addressing the integration of environmental, social and economic dimensions leading to an interpretation that ESD is mainly about environment and conservation issues; New learning (rather than teaching) approaches are called for to promote more debate in society. Yet, few are trained or experienced in these new approaches. Practitioners need support to explore new ways of promoting learning. [Foreword, ed].
