This book was released on 2003-01-01 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Action is needed to fight poverty by sustaining the environment and the use of natural resources. Land Quality, Agricultural Productivity, and Food Security explores a range of factors driving food security. The book offers an assessment to link quality of the available land resources with productivity of land and the ability to ensure food security. It offers a mixture of broad-scale assessments across the globe, with detailed case studies, deepening our understanding of economics and decision-making mechanisms. It is recommended to researchers, as well as actors in the private and public domain, who are keen to improve their understanding of the appropriate actions that ensure food security in the decade to come.' - Floor Brouwer, Agricultural Economics Research Institute (LEI), The Hague, The Netherlands Land quality and land degradation affect agricultural productivity and food security, but quantifying these relationships has been difficult. Data are extremely limited and outcomes are sensitive to the choices that farmers make. The contributors to this book - including soil scientists, geographers, and economists - analyse data on soils, climate, land cover, agricultural inputs and outputs, and a variety of socio-economic factors to provide new insights into three key issues: * the extent to which differences in land quality generate differences in agricultural productivity across countries * how farmers' responses to differences or changes in land quality are influenced by economic, environmental, and institutional factors, and * whether land degradation over time threatens productivity growth and food security at local, regional, and global levels.

Download or read book Farm Size and Productivity written by Douglas Gollin and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This paper considers the relationship between farm size and productivity. It begins by discussing measurement issues and conceptual issues related to agricultural productivity, including the well-documented difficulty of measuring inputs and outputs in smallholder production systems. The paper then considers the relationship between farm size and productivity, documenting patterns both across countries and within countries. Across countries, there is a weak but positive relationship between farm size and the value of agricultural output per unit of land (i.e. yield). A much stronger positive relationship holds for agricultural output per unit of labour, which is closely correlated with farm size across countries. Within countries, the relationship between farm size and yield is often negative (the widely documented 'inverse farm size-productivity relationship'). However, even within countries, there is typically a strong positive relationship between farm size and labour productivity. The paper concludes by considering the policy implications, if any, of the relationships between farm size and agricultural productivity"--Page 4.

Download or read book The Vanishing Farmland Crisis written by John Baden and published by University Press of Kansas. This book was released on 2021-10-08 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Newspapers seem to be telling us that every cornfield is threatened by a Dairy Queen. This media barrage about the crisis of our “shrinking” farmland can be traced to the 1979 publication of Where Have All the Farmlands Gone? by the National Agricultural Lands Study. The NALS report, to which eleven federal agencies contributed, argued that land-use planning and control must be employed to protect valuable farmland from “urban sprawl.” This volume, a collection of essays by a distinguished group of economists including Theodore W. Schultz, Julian L. Simon, and Pierre Crosson, takes issue with the belief that croplands need governmental protection. In opposition the collection as a whole supports two theses: 1) shrinking farm acreage is not a serious problem, and 2) individual choices by landowners in a market setting result in better-organized land use than would governmental land-use planning and regulation.

Download or read book Scenario Studies for the Rural Environment written by Job F.Th. Schoute and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rural areas need to fulfil a large variety of functions and to accommodate many activities. The complexity of the problems, limited funds, and the almost irreversible character of some interventions result in a compelling need to evaluate ex ante the effects of alternative solutions for designation of land, for measures to develop infrastructure, and for soil and water management. Scenario studies are undertaken to help manage the complexity, to place bounds on uncertainties, and to create new visions. After an overview of the nature, variety and scope of scenario studies, the book illuminates various European examples and reviews, under the following headings: regional soil and water management; nature development and landscape quality; rural planning and the future of regions.

Download or read book Landscape and Land Capacity written by Yeqiao Wang and published by CRC Press. This book was released on 2020-05-19 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Authored by world-class scientists and scholars, The Handbook of Natural Resources, Second Edition, is an excellent reference for understanding the consequences of changing natural resources to the degradation of ecological integrity and the sustainability of life. Based on the content of the bestselling and CHOICE-awarded Encyclopedia of Natural Resources, this new edition demonstrates the major challenges that the society is facing for the sustainability of all well-being on the planet Earth. The experience, evidence, methods, and models used in studying natural resources are presented in six stand-alone volumes, arranged along the main systems of land, water, and air. It reviews state-of-the-art knowledge, highlights advances made in different areas, and provides guidance for the appropriate use of remote sensing and geospatial data with field-based measurements in the study of natural resources. Volume 2, Landscape and Land Capacity, covers soils and landscape issues, their diversity and importance, and how soils are related to the landscapes in which they form. It includes discussions on land conservation, land-use and land-cover changes, and urban environments and unravels the complex bond between humans and soils. New in this edition are discussions on habitat conservation and planning, landscape epidemiology and vector-borne disease, and landscape patterns and changes. This volume demonstrates the key processes, methods, and models used through several practical case studies from around the world. Written in an easy-to-reference manner, The Handbook of Natural Resources, Second Edition, as individual volumes or as a complete set, is an essential reading for anyone looking for a deeper understanding of the science and management of natural resources. Public and private libraries, educational and research institutions, scientists, scholars, and resource managers will benefit enormously from this set. Individual volumes and chapters can also be used in a wide variety of both graduate and undergraduate courses in environmental science and natural science at different levels and disciplines, such as biology, geography, earth system science, and ecology.
