Book Description
Since the 1980s many developing countries have implemented macro-economic policy reforms to curb inflation, reduce fiscal deficits and control foreign debt. The policy instruments used, such as exchange rate adjustment, budget cuts, trade policy reforms, public expenditure reviews and privatisation, have different and sometimes opposite consequences for agricultural land use. During the same period awareness was growing that deteriorating soil quality could become a limiting factor to increase or even sustain agricultural production. As a result, food availability and even accessibility for large population groups in developing countries may be jeopardised in the near future. Recently, quantitative models have made useful contributions to understanding the impact of economic policy reforms on the sustainability of land use. They provide a consistent analytical framework to deal with complex issues such as the direct and indirect effects of economic, agricultural, environmental and population policies, the role of market imperfections in transmitting economic policy signals, and the interactions between soil quality, agricultural production and household economic decision making. Different types of models can be distinguished: bio economic models, focussing on the link between farm household decisions and the agricultural resource base, household and village models, examining the impact of the socio-economic environment on farm household decisions, and more aggregate models, analysing interactions between sectors and their implications for sustainable land use.

Book Description
This book takes a new approach on understanding causes of extreme poverty and promising actions to address it. Its focus is on marginality being a root cause of poverty and deprivation. “Marginality” is the position of people on the edge, preventing their access to resources, freedom of choices, and the development of capabilities. The book is research based with original empirical analyses at local, national, and local scales; book contributors are leaders in their fields and have backgrounds in different disciplines. An important message of the book is that economic and ecological approaches and institutional innovations need to be integrated to overcome marginality. The book will be a valuable source for development scholars and students, actors that design public policies, and for social innovators in the private sector and non-governmental organizations.

Book Description
A book on the economics of exhaustible resources requires no justification. A long book does. The purist will find disquieting our two-asset, constant population model with which we analyse growth possibilities in an economy with exhaustible resources.

Book Description
This book reflects the results of more than ten years of cooperative research involving Wageningen Agricultural University (y. l AU) in the Netherlands, the Tropical Agricultural Research and Higher Education Center (CATIE; Centro Agron6mico Tropical de lnvestigaci6n y Ensefianza) in Costa Rica and the Costa Rican Ministry of Agriculture and Livestock (MAG; Ministerio de Agricultura y Ganadeda) as part of the Research Program on Sustainability in Agriculture (REPOSA) in the Central American country. The type of cooperation was unusual as it focused on both research and the education of students undertaking either M. Sc. thesis projects or a program of practical training in the various aspects of studying land use. Since funding was provided by W AU, a high degree of scientific autonomy was created that has clearly benefited the independent, scientific rigor of the work. Over the ten-year period, the program has changed from being a patchwork of various insulated specialist projects, into a truly interdisciplinary effort, leading to the development of innovative tools for analyzing land use on a number of geographical scales. These tools are presented in this book. Besides CATIE and MAG, cooperation with other Costa Rican partner institutions has been essential from the beginning, and this process of interaction has also evolved considerably over time.

Book Description
Land degradation is increasingly considered as a global problem. The extent of degraded and degrading areas adversely impacts on large numbers of people and leads to significant social and economic costs, thus raising the questions: In which way is it worth taking action against land degradation? Where and when should action take place, and what are costs related to certain actions? For policy makers it is important to know the social and economic costs linked to the current and future status of land degradation. A conceptual framework that allows comparing the costs of action against land degradation versus the costs of inaction is provided in this book. The applicability of the framework is illustrated with case studies and prepares the ground for a global assessment on the costs of land degradation.

Book Description
The objective of IFAD/FAO consultation was to bring together experts in order to review the state-of-the-art knowledge in carbon sequestration for the land management programmes IFAD and FAO in Latin America and the Caribbean. The main objectives addressed were: how to stabilize the atmospheric concentration of CO2; how to increase agricultural productivity and reduce rural poverty; in view of the Global Mechanism for Desertification Convention, how to activiate the flow of new funds for the benefit of Convention implementation through carbon sequestration, i.e. its binding and neutralisation. It is believed that carbon stock in soils is either stable or increasing and that it is was a major source of global carbon emission, a major cause of global climate change

Book Description
'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.

Book Description
This book has been developed from a workshop on Technological change in agriculture and tropical deforestation organised by the Center for International Forestry Research and held in Costa Rica in March, 1999. It explores how intensification of agriculture affects tropical deforestation using case studies from different geographical regions, using different agricultural products and technologies and in differing demographic situations and market conditions. Guidance is also given on future agricultural research and extension efforts.

Book Description
This book contains a selection of the latest research in the field of Computational Social Science (CSS) methods, uses, and results, as presented at the 2018 annual conference of the CSSSA. This conference was held in Santa Fe, New Mexico, October 25 – 28, 2018, at the Drury Plaza Hotel. CSS investigates social and behavioral dynamics in both nature and society, through computer simulation, network analysis, and the science of complex systems. The Computational Social Science Society of the Americas (CSSSA) is a professional society that aims to advance the field of CSS in all its areas, from fundamental principles to real-world applications, by holding conferences and workshops, promoting standards of scientific excellence in research and teaching, and publishing novel research findings. What follows is a diverse representation of new approaches and research findings, using the tools of CSS and Agent-Based Modeling (ABM) in exploring complex phenomena across many different domains. Readers will not only have the methods and results of these specific projects on which to build, but will also gain a greater appreciation for the broad scope of CSS, and have a wealth of case-study examples that can serve as meaningful exemplars for new research projects and activities. This book, we hope, will appeal to any researchers and students working in the social sciences, broadly defined, who aim to better understand and apply the concepts of Complex Adaptive Systems to their work.
