Soil organic matter - the product of on-site biological decomposition - affects the chemical and physical properties of the soil and its overall health. Its composition and breakdown rate affect: the soil structure and porosity; the water infiltration rate and moisture holding capacity of soils; the diversity and biological activity of soil organisms; and plant nutrient availability. This document concentrates on the organic matter dynamics of cropping soils and discusses the circumstances that deplete organic matter and their negative outcomes. It then moves on to more proactive solutions. It reviews a "basket" of practices in order to show how they can increase organic matter content and discusses the land and cropping benefits that then accrue.--Publisher's description.
With new momentum, the Brazilian black movement is working to bring attention to and change the situation of structural racism in Brazil. Black consciousness advocates are challenging Afro-Brazilians to define themselves and politically organize around being black, and more Afro-Brazilians are increasingly doing so. Other segments of the Brazilian black movement are working to influence legislation and implement formal mechanisms that aim to promote racial equality, including Affirmative Action Racial Verification Committees. For advocates of these committees, one needs to be phenotypically black enough to be a more likely target of racism to qualify for Affirmative Action programs. Paradoxically, individuals are told to identify as black but only some people are considered black enough to benefit from these policies. Afro-Brazilians are presented with a whole range of identity choices, from how to classify oneself, to whether one votes for political candidates based on shared racial experiences. Between Brown and Black argues that Afro-Brazilian activists’ continued exploration of blackness confronts anti-blackness while complicating understandings of what it means to be black. Blending linguistic and ethnographic accounts, this book raises complex questions about current black struggles in Brazil and beyond, including the black movements’ political initiatives and antiracist agenda.
Health care demands more and more cooperation and the convergence of all health related sciences, from Life Molecules to Global Health, as was most recently shown by the challenge of the COVID pandemic. This book brings together science contributions from NOVA’s researchers on biology and health, in the format of a broad life construct book.
