Los parientes silvestres de cultivos son posibles fuentes de caracteres deseables para la obtención de variedades bien adaptadas, mientras que las plantas silvestres comestibles son componentes importantes de la dieta de muchas personas en todo el mundo. Lamentablemente, sus hábitats silvestres naturales están cada vez más amenazados por las actividades humanas y las catástrofes naturales. La pérdida de hábitat repercute de manera directa y negativa en la diversidad de estos valiosos recursos. Las presentes directrices, concebidas como material de referencia para la elaboración de un Plan nacional para la conservación y el uso sostenible de parientes silvestres de cultivos y plantas silvestres comestibles, contribuirán a frenar esta continua pérdida de diversidad. Las directrices son, por consiguiente, un instrumento útil para profesionales del desarrollo, investigadores, estudiantes y responsables de la formulación de políticas que trabajan en la conservación y el uso sostenible de estos valiosos recursos.

Renaissance in the Tropics

GAVIOTAS, For the recovery of Earth’s skin There is a new start towards the world. One age that Mario Calderon Rivera, outstanding thinker and humanist, called Renaissance in the sense of both the Italian Renaissance as a change of mind of man to himself, and the contemporary one as a change of mind from man towards nature. The Renaissance, led by this brilliant saying of Leonardo da Vinci: "Everything comes from everything, and everything is made out of everything, and everything returns into everything" especially in a round planet. This also comes to be true in Centro "Las Gaviotas" where they achieved, among other things, the reawakening of the Amazon rainforest in the Colombian savannas of Orinoco. There they join the community welfare with the wealth generated by the sustainable use of tropical biodiversity, which, being located in the equatorial zone, has one of the highest rates of biological productivity. Within this context, Mario Calderon, travels through the last 60 years showing the ideas of the human being when he began to reflect on the effects of his action on Earth. They consist of a new attitude towards nature, seeing himself as being part of one system, with it he can coexist without destroying, understanding their connections, i.e. its complexity. Gaviotas age is this way of thinking. The author in honor of Gaviotas and its founder, Paolo Lugari, sets the theoretical foundations of the progress mankind has made in this respect since the last half century. Gaviotas is an example, a path, but at the same time an outpost of a bioculture that makes its way to protect both human life as well as that from others, which ultimately are subjected to the recovery of the vegetable skin of Earth, by the increase in biomass, as this determines the dynamic stability of the composition of the atmosphere of 99%, of nitrogen and oxygen If this composition would be disturbed by the continuing decline in biomass it would make impossible for human life to exist, something much more serious than global warming. Just warming is only a reductionist analysis of the issue. Development is seen now in productive harmony with nature, without undermining the very foundations of civilization. With an extensive knowledge of the authors who have made the ecological thinking trends of our time, Calderón contextualizes Gaviotas in the present world highlighting its conceptual contributions and its innovative achievements, always pointing to a decent lifestyle without denying the modernity.

This book focuses on recent advances in our understanding of wild edible mycorrhizal fungi, truffle and mushrooms and their cultivation. In addition to providing fresh insights into various topics, e.g. taxonomy, ecology, cultivation and environmental impact, it also demonstrates the clear but fragile link between wild edible mushrooms and human societies. Comprising 17 chapters written by 41 experts from 13 countries on four continents, it enables readers to grasp the importance of protecting this unique, invaluable, renewable resource in the context of climate change and unprecedented biodiversity loss. The book inspires professionals and encourages young researchers to enter this field to develop the sustainable use of wild edible mushrooms using modern tools and approaches. It also highlights the importance of protecting forested environments, saving species from extinction and generating a significant income for local populations, while keeping alive and renewing the link between humans and wild edible mushrooms so that in the future, the sustainable farming and use of edible mycorrhizal mushrooms will play a predominant role in the management and preservation of forested lands.
