La transición energética hizo cobrar nueva importancia a los yacimientos metalíferos y no metalíferos y generó un nuevo patrón de demanda, especialmente para el caso del litio. Los actores importantes en la cadena de valor de las baterías de ion-litio intensificaron su control sobre cada etapa de sus negocios, y las políticas de los países abundantes en litio son cruciales para determinar cómo afecta a sus territorios esta carrera por el litio. Jujuy, una provincia que podría considerarse periférica de la Argentina, declaró el litio como un recurso estratégico en 2011. La provincia creó ciertos instrumentos para ejercer mayor control …

Development Of Enhanced Algae Strains And Sustainable Cultivation Processes For Production Of Algal Lipids For Biofuels And Bioproducts, Enlin Lo
USF Tampa Graduate Theses and Dissertations
The establishment of an algae industry is crucial for addressing global biofuel and bioproduct demand that meets the Sustainable Development Goals (SDG) worldwide. Photosynthetic microalgae are excellent sources for food, fiber, fuel, feed, and fertilizer, which are the 5Fs of the SDG. However, at present, algae-based materials are not cost-competitive or sufficiently sustainable. Improved productivity, lower cultivation cost, and reduced use of resources are required to transition from lab to industry, necessitating the development of superior strains that have high productivity and can tolerate environmental stress, such as temperature and salinity, so they can be cultivated at large scale outdoors …
Thinking Creatively About Functional Diversity And Functional Traits (Bef),

Columbia University
Thinking Creatively About Functional Diversity And Functional Traits (Bef), Shahid Naeem
Sustainability Seminar Series
Understanding the impacts of biodiversity loss on ecosystem functions and services represents a major focus of contemporary environmental biology, but its progress hinges on advances in the study of functional diversity. Traditional approaches to functional diversity, however, have centered on taking virtually any measure of an organism’s biology, or an organism’s functional traits (OFTs), often assuming that variation in OFTs among species reflects ecological and evolutionary tradeoffs. Contemporary issues, however, require more creative approaches to the quantification and analysis of OFTs. Here, I present results from four of our group’s research that illustrate the value of more creative approaches to …
