En la Tercera Edición de este texto se amplía el análisis de los procesos que están dando lugar al surgimiento del sujeto ambiental como actor político, teniendo como referentes la Minga indígena, la movilización social por la defensa del Páramo de Santurban contra la minería de oro; las movilizaciones campesinas y populares contra la represa del Quimbo, que afecta gravemente el río Magdalena, la resistencia contra la minería de oro en Cajamarca y el triunfo de la movilización local contra la Planta de Ecopetrol en Villa de Leyva. También se analizan las principales movilizaciones en América Latina, en países como Brasil, Perú y Bolivia. Se cuestiona la Economía Verde u otras facetas igualmente engañosas que esconden intereses de transnacionales de la energía, la farmacopea, los alimentos y el mercado del carbono. Esperamos que estas reflexiones sirvan a los lectores y estudiosos de la problemática ambiental a todos los niveles para adentrarse en el conocimiento de la ecología política, la economía ecológica y la historia ambiental.

One of the biggest threats to the survival of many plant and animal species is the destruction or fragmentation of their natural habitats. The conservation of landscape connections, where animals, plants, and ecological processes can move freely from one habitat to another, is therefore an essential part of any new conservation or environmental protection plan. In practice, however, maintaining, creating, and protecting connectivity in our increasingly dissected world is a daunting challenge. This fascinating volume provides a synthesis on the current status and literature of connectivity conservation research and implementation. It shows the challenges involved in applying existing knowledge to real-world examples and highlights areas in need of further study. Containing contributions from leading scientists and practitioners, this topical and thought-provoking volume will be essential reading for graduate students, researchers, and practitioners working in conservation biology and natural resource management.
