Available in PDF, EPUB and Kindle. Book excerpt: Soil-plant relationships once had a limited meaning. To the student of agriculture it meant creating optimum conditions for plant growth. To the ecologist it meant explaining some plant community distribu tion patterns by correlation with soil type or conditions. This dual view has been greatly expanded at an academic level by the discovery of the ecosystem as a practical working unit. A flood of concepts and information subsequently emerged from the International Biological Programme. At a totally different level of resolution, it is appreciated that certain soil-based ecological problems have a molecular basis, and must be addressed by physiological or biochemical approaches. From ecosystem to molecule we have powerful new tools to increase the flow of ecological data and process it for interpretation. Society is now experiencing a series of adverse global phenomena which demand an appreciation of soil-plant relationships. These include desertification leading to famine, soil degradation accom panying forest destruction, acidification of watersheds and the spasmodic dispersal of radionuclides and other pollutants. It is public policy, not merely to identify problems, but to seek strategies for minimising their ill effects. This book is written as a guide to soil-plant relationships, cen trally oriented towards ecology, but of interest to students of geo graphy and agriculture. For ecology students it will bring together subfields such as microbiology, plant physiology, systematics and pro vide interfaces with animal biology, meteorology and soil science.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Plant Structures a Second Book of Botany In the preface to Plant Relations the author gave his reasons for suggesting that the ecological standpoint is best adapted for the first contact with plants. It may be, however, that many teachers will prefer to begin with the morphological standpoint, as given in the present book. Recognizing this fact, Plant Structures has been made an independent volume that may precede or follow the other, or may provide a brief course of botanical study in itself. Although in the present volume Morphology is the dominant subject, it seems wise to give a somewhat general view of plants, and therefore Physiology, Ecology, and Taxonomy are included in a general way. For fear that Physiology and Ecology may be lost sight of as distinct subjects, and to introduce important topics not included in the body of the work, short chapters are devoted to them, which seek to bring together the main facts, and to call attention to the larger fields. This book is not a laboratory guide, but is for reading and study in connection with laboratory work. An accompanying pamphlet for teachers gives helpful suggestions to those who are not already familiar with its scope and purpose. It is not expected that all the forms and subjects presented, in the text can be included in the laboratory exercises but it is believed that the book will prove a useful companion in connection with such exercises.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers an original analysis and theorization of the biopolitics of development in the postcolonial present, and draws significantly from the later works of Michel Foucault on biopolitics. Foucault’s works have had a massive influence on postcolonial literatures, particularly in political science and international relations, and several authors of this book have themselves made significant contributions to that influence. While Foucault’s thought has been inspirational for understanding colonial biopolitics as well as governmental rationalities concerned with development, his works have too often failed to inspire studies of political subjectivity. Instead, they have been used to stoke the myth of the inevitability of the decline of collective political subjects, often describing an increasingly limited horizon of political possibilities, and provoking a disenchantment with the political itself in postcolonial works and studies. Working against the grain of current Foucauldian scholarship, this book underlines the importance of Foucault’s work for the capacity to recognize how this degraded view of political subjectivity came about, particularly within the framework of the discourses and politics of ‘development’, and with particular attention to the predicaments of postcolonial peoples. It explores how we can use Foucault’s ideas to recover the vital capacity to think and act politically at a time when fundamentally human capacities to think, know and to act purposively in the world are being pathologized as expressions of the hubris and ‘underdevelopment’ of postcolonial peoples. Why and how it is that life in postcolonial settings has been depoliticized to such dramatic effect? The immediacy of these themes will be obvious to anyone living in the South of the world. But within the academy they remain heavily under-addressed. In thinking about what it means to read Michel Foucault today, this book tackles some significant questions and problems: Not simply that of how to explain the ways in which postcolonial regimes of governance have achieved the debasements of political subjectivity they have; nor that of how we might better equip them with the means to suborn the life of postcolonial peoples more fully; but that of how such peoples, in their subjection to governance, can and do resist, subvert, escape and defy the imposition of modes of governance which seek to remove their lives of those very capacities for resistance, subversion, flight, and defiance.
Download or read book Climate smart Agriculture Sourcebook written by Food and Agriculture Organization (FAO) and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Climate-smart agriculture, forestry and fisheries (CSA), contributes to the achievement of sustainable development goals. It integrates the three dimensions of sustainable development (economic, social and environmental) by jointly addressing food security and climate challenges. It is composed of three main pillars: sustainably increasing agricultural productivity and incomes; adapting and building resilience to climate change; reducing and/or removing greenhouse gases emissions, where possible. The purpose of the sourcebook is to further elaborate the concept of CSA and demonstrate its potential, as well as limitations. It aims to help decision makers at a number of levels (including political administrators and natural resource managers) to understand the different options that are available for planning, policies and investments and the practices that are suitable for making different agricultural sectors, landscapes and food systems more climate-smart. This sourcebook is a reference tool for planners, practitioners and policy makers working in agriculture, forestry and fisheries at national and subnational levels." -- Back cover.

This book was released on 2013-06-29 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Policy failures in environment and development have been blamed on frag mented and eclectic policies and strategies. The 1992 United Nations Con ference on Environment and Development, the 'Earth Summit' in Rio de Janeiro, called therefore for an integrated approach in planning and policy making to achieve long-term sustainable growth and development. The Con ference also recognized in its action plan, the Agenda 21, that integrated poli cies need to be supported by integrated information, notably requiring the implementation of integrated environmental and economic accounting by its member States. During the preparations for the Rio Summit, scientists and practitioners of national accounting met in a Special Conference on Environmental Account ing, organized by the International Association for Research in Income and Wealth (IARIW) in Baden, Austria. Their aim was to explore the need for and methodologies of adjusting national accounts for environmental reasons. National accountants had faced mounting criticism that conventional accounting neglected new scarcities in natural capital, as well as the social cost of environmental degradation. The result of their deliberations was a draft manual, later issued by the United Nations Statistics Division (UNSD) as a handbook of Integrated Environmental and Economic Accounting.
