Embracing diverse worldviews to share planet Earth
Leading societies toward a more sustainable, equitably shared, and environmentally just future requires elevating and strengthening conversations on the nonmaterial and perhaps unquantifiable values of nonhuman nature to humanity. Debates among conservationists relating to the appropriateness of valuing ecosystems in terms of their human utility have eclipsed the more important and impactful task of expressing conservation concerns in terms that are meaningful to diverse stakeholders. We considered the wide global diversity of perspectives on the biosocial complexâthe relationships and interactions between all living species on Earthâand argue that humanity's best chance for effective conservation is to take a pluralistic approach that engages seriously with the worldviews of all stakeholders. Many worldviewsâparticularly those in indigenous culturesâplace a higher value on the spiritual and nonmaterial aspects than what is often represented by the discourse surrounding Western conservation policy. Alternative framings of the biosocial complex that recognize nature's intrinsic value can be powerful motivators for social change and for localâscale conservation efforts. At a national and international level, changing ethical framings of human relationships with nature have started influencing conceptions of human rights relating to the environment and of the rights of nature itself. This change has led to an increased role of the judiciary in promoting environmental sustainability and promoting justice for groups who are most often affected by environmental harms. We hope our essay will motivate the scientific community to change its own perception of what a sound and sustainable relationship between humanity and other species should be and will help citizens become active environmental subjects, connected to the ecosystems around them.peerReviewe
Organic-inorganic hybrid sol-gelcoatings for metal corrosion protection: a review of recent progress
This paper is a review of the most recent and relevant achievements (from 2001 to 2013) on the development of organicâinorganic hybrid (OIH) coatings produced by solâgel-derivedmethods to improve resistance to oxidation/corrosion of different metallic substrates and their alloys. This review is focused on the research of OIH coatings based on siloxanes using the solâgel process conducted at an academic level and aims to summarize the materials developed and identify perspectives for further research. The fundamentals of solâgel are described, including OIH classification, the interaction with the substrate, their advantages, and limitations. The main precursors used in the synthesis ofOIHsolâgel coatings for corrosion protection are also discussed, according to the metallic substrate used. Finally, a multilayer system to improve the resistance to corrosion is proposed, based on OIH coatings produced by the solâgel process, and the future research challenges are debated.FundacĂŁo para a CiĂȘncia e Tecnologia (FCT) for the PhD grant SFRH/BD/62601/2009, Centro de QuĂmica [project F-COMP-01-01024-FEDER-022716 (ref.
