Soils: Basic Concepts and Future Challenges
This book was born as an international tribute to Fiorenzo C. Ugolini, an outstanding soil scientist, now retired from university teaching and research. It is a synthesis of the knowledge of soils, their genesis, functions and management, and includes contributions from leading soil scientists. It provides the basic concepts as well as data and practical examples from across the discipline. The book also discusses the increasingly important role of soils in enabling the preservation of life and contains a rare attempt to cross-harmonize the Soil Groups of the World Reference Base of Soil Resources with the Orders of the Soil Taxonomy. It also considers the possible existence of extraterrestrial soils based on the findings from the last space missions. This volume will be a valuable resource for researchers and students of soil science, soil conservation, geography and landscape ecology.

Removal of Phosphorus from Aqueous Solutions Using Cactus Pear Pruning Waste
The potential of cactus pear pruning waste, as low-cost adsorbent biomass to remove phosphorus (P) from aqueous solution, was studied in batch mode. Biomass from cactus pear, natural and enriched in Ca or Fe, was used. The removal capacity of phosphorus in biomass enriched in Ca2+, Fe2+ and Fe3+ was 2.27, 1.33 and 1.87 mg g-1, respectively.The Langmuir isotherm was found to be the best model in the study of P adsorption, for biomass enriched in Ca2+, Fe2+ and Fe3+. Pseudo-first-order, pseudo-second-order, and intraparticle diffusion models were applied to describe the kinetic data. The best fit was obtained for the pseudo-second-order model. The desorption/regeneration process was also studied revealing less than 8% desorption of phosphorus in Ca or Fe-enriched biomass, and showing strong stability of the biomass-cation-phosphorus system. Therefore, cactus pear pruning waste, previously reduced to powder and enriched with ions, could be a cheap adsorbent with a good P removal performance, which could be used directly in agriculture as a soil conditioner/fertilizer.
Anthropocene or Capitalocene?
The Earth has reached a tipping point. Runaway climate change, the sixth great extinction of planetary life, the acidification of the oceans—all point toward an era of unprecedented turbulence in humanity’s relationship within the web of life. But just what is that relationship, and how do we make sense of this extraordinary transition? Anthropocene or Capitalocene? offers answers to these questions from a dynamic group of leading critical scholars. They challenge the theory and history offered by the most significant environmental concept of our times: the Anthropocene. But are we living in the Anthropocene, literally the “Age of Man”? Is a different response more compelling, and be...
The Birth of the Anthropocene
The world faces an environmental crisis unprecedented in human history. Carbon dioxide levels have reached heights not seen for three million years, and the greatest mass extinction since the time of the dinosaurs appears to be underway. Such far-reaching changes suggest something remarkable: the beginning of a new geological epoch. It has been called the Anthropocene. The Birth of the Anthropocene shows how this epochal transformation puts the deep history of the planet at the heart of contemporary environmental politics. By opening a window onto geological time, the idea of the Anthropocene changes our understanding of present-day environmental destruction and injustice. Linking new developments in earth science to the insights of world historians, Jeremy Davies shows that as the Anthropocene epoch begins, politics and geology have become inextricably entwined.
The Evolution of Knowledge
Jürgen Renn examines the role of knowledge in global transformations going back to the dawn of civilization while providing vital perspectives on the complex challenges confronting us today in the Anthropocene--this new geological epoch shaped by humankind. Renn reframes the history of science and technology within a much broader history of knowledge, analyzing key episodes such as the evolution of writing, the emergence of science in the ancient world, the Scientific Revolution of early modernity, the globalization of knowledge, industrialization, and the profound transformations wrought by modern science. He investigates the evolution of knowledge using an array of disciplines and methods, from cognitive science and experimental psychology to earth science and evolutionary biology. The result is an entirely new framework for understanding structural changes in systems of knowledge--and a bold new approach to the history and philosophy of science.
PHEs, Environment and Human Health
This book is dedicated to the occurrence and behaviour of PHEs in the different compartments of the environment, with special reference to soil. Current studies of PHEs in ecosystems have indicated that many industrial areas near urban agglomerates, abandoned or active mines, major road systems and ultimately also agricultural land act as sources and at the same time sinks, of PHEs and large amounts of metals are recycled or dispersed in the environment, posing severe concerns to human health. Thanks to the collaboration of numerous colleagues, the book outlines the state of art in PHEs research in several countries and is enforced with case studies and enriched with new data, not published elsewhere. The book will provide to Stakeholders (both Scientists Professionals and Public Administrators) and also to non-specialists a lot of data on the concentrations of metals in soils and the environment and the critical levels so far established, in the perspective to improve the environmental quality and the human safety.
Amazonia in the Anthropocene
Widespread human alteration of the planet has led many scholars to claim that we have entered a new epoch in geological time: the Anthropocene, an age dominated by humanity. This ethnography is the first to directly engage the Anthropocene, tackling its problems and paradoxes from the vantage point of the world’s largest tropical rainforest. Drawing from extensive ethnographic research, Nicholas Kawa examines how pre-Columbian Amerindians and contemporary rural Amazonians have shaped their environment, describing in vivid detail their use and management of the region’s soils, plants, and forests. At the same time, he highlights the ways in which the Amazonian environment resists human manipulation and control—a vital reminder in this time of perceived human dominance. Written in engaging, accessible prose, Amazonia in the Anthropocene offers an innovative contribution to debates about humanity’s place on the planet, encouraging deeper ecocentric thinking and a more inclusive vision of ecology for the future.
