People are constantly changing the land surface through construction, agriculture, energy production, and other activities. Changes both in how land is used by people (land use) and in the vegetation, rock, buildings, and other physical material that cover the Earth's surface (land cover) can be described and future land change can be projected using land-change models (LCMs). LCMs are a key means for understanding how humans are reshaping the Earth's surface in the past and present, for forecasting future landscape conditions, and for developing policies to manage our use of resources and the environment at scales ranging from an individual parcel of land in a city to vast expanses of forests around the world. Advancing Land Change Modeling: Opportunities and Research Requirements describes various LCM approaches, suggests guidance for their appropriate application, and makes recommendations to improve the integration of observation strategies into the models. This report provides a summary and evaluation of several modeling approaches, and their theoretical and empirical underpinnings, relative to complex land-change dynamics and processes, and identifies several opportunities for further advancing the science, data, and cyberinfrastructure involved in the LCM enterprise. Because of the numerous models available, the report focuses on describing the categories of approaches used along with selected examples, rather than providing a review of specific models. Additionally, because all modeling approaches have relative strengths and weaknesses, the report compares these relative to different purposes. Advancing Land Change Modeling's recommendations for assessment of future data and research needs will enable model outputs to better assist the science, policy, and decisionsupport communities.

The conjunction of climate, food, and financial crises in the late 2000s triggered renewed interest in farmland and agribusiness investments around the world. This phenomenon became known as the "global land grab", and sparked vibrant debates among social movements, NGOs, international development agencies and various government agencies and academics worldwide. This book addresses four key areas that are moving the debate "beyond land grabs". These include the role of contract farming and differentiation among farm workers in the consolidation of farmland; the broader forms of dispossession and mechanisms of control and value grabbing beyond "classic" land grabs for agricultural production; discourses about, and responses to, Chinese agribusiness investments abroad; and the relationship between financialization and land grabbing. The chapters in this edited volume propose new directions to deepen and even transform the research agenda on land struggles and agro-industrial restructuring around the world. This book will be of great interest to scholars and researchers interested in development studies, agrarian changes and land struggles. The chapters in this book were originally published as a special issue of the journal, Globalizations.

Population, Land Use, and Environment: Research Directions offers recommendations for future research to improve understanding of how changes in human populations affect the natural environment by means of changes in land use, such as deforestation, urban development, and development of coastal zones. It also features a set of state-of-the-art papers by leading researchers that analyze population-land useenvironment relationships in urban and rural settings in developed and underdeveloped countries and that show how remote sensing and other observational methods are being applied to these issues. This book will serve as a resource for researchers, research funders, and students.

Arizona’s San Pedro Valley is a natural corridor through which generations of native peoples have traveled for more than 12,000 years, and today many tribes consider it to be part of their ancestral homeland. This book explores the multiple cultural meanings, historical interpretations, and cosmological values of this extraordinary region by combining archaeological and historical sources with the ethnographic perspectives of four contemporary tribes: Tohono O’odham, Hopi, Zuni, and San Carlos Apache. Previous research in the San Pedro Valley has focused on scientific archaeology and documentary history, with a conspicuous absence of indigenous voices, yet Native Americans maintain oral traditions that provide an anthropological context for interpreting the history and archaeology of the valley. The San Pedro Ethnohistory Project was designed to redress this situation by visiting archaeological sites, studying museum collections, and interviewing tribal members to collect traditional histories. The information it gathered is arrayed in this book along with archaeological and documentary data to interpret the histories of Native American occupation of the San Pedro Valley. This work provides an example of the kind of interdisciplinary and politically conscious work made possible when Native Americans and archaeologists collaborate to study the past. As a methodological case study, it clearly articulates how scholars can work with Native American stakeholders to move beyond confrontations over who “owns” the past, yielding a more nuanced, multilayered, and relevant archaeology.

Drawing from field research in Cameroon, Ghana, Vietnam, and the Amazon forests of Brazil, Bolivia, and Peru, this book explores the relationship between gender and land, revealing the workings of global capital and of people's responses to it. A central theme is the people's resistance to global forces, frequently through an insistence on the uniqueness of their livelihoods. For instance, in the Amazon, the focus is on the social movements that have emerged in the context of struggles over land rights concerning the extraction of Brazil nuts and babacu kernels in an increasingly globalised market. In Vietnam, the process of 'de-collectivising' rights to land is examined with a view to understand how gender and other social differences are reworked in a market economy. The book addresses a gap in the literature on land tenure and gender in developing countries. It raises new questions about the process of globalisation, particularly about who the actors are (local people, the state, NGOs, multinational companies) and the shifting relations amongst them. The book also challenges the very concepts of gender, land and globalization.

"The challenges facing agriculture are plenty. Along with the world's growing population and diminishing amounts of water and arable land, the gradual increase in severe weather presents new challenges and imperatives for producing new, more resilient crops to feed a more crowded planet in the twenty-first century. Innovation has historically helped agriculture keep pace with earth's social, population, and ecological changes. In the last 50 years, mechanical, biological, and chemical innovations have more than doubled agricultural output while barely changing input quantities. The ample investment behind these innovations was available because of a high rate of return: a 2007 paper found that the median ROI in agriculture was 45 percent between 1965 and 2005. This landscape has changed. Today many of the world's wealthier countries have scaled back their share of GDP devoted to agricultural R&D amid evidence of diminishing returns. Universities, which have historically been a major source of agricultural innovation, increasingly depend on funding from industry rather than government to fund their research. As Upton Sinclair wrote of the effects industry influences, "It is difficult to get a man to understand something when his salary depends upon his not understanding it." In this volume of the NBER Conference Report series, editor Petra Moser offers an empirical, applied-economic framework to the different elements of agricultural R&D, particularly as they relate to the shift from public to private funding. Individual chapters examine the sources of agricultural knowledge and investigate challenges for measuring the returns to the adoption of new agricultural technologies, examine knowledge spillovers from universities to agricultural innovation, and explore interactions between university engagement and scientific productivity. Additional analysis of agricultural venture capital point to it as an emerging and future source of resource in this essential domain"--
