Book Description
Global cropland is expanding with changing trends in both the production and consumption of land-based products, increasing pressure on land resources across the globe. This report discusses the need to balance consumption with sustainable production. It focuses on land-based products and describes methods which enable countries to determine whether their consumption levels exceed sustainable supply capacities.

Book Description
Global land use plays a central role in determining our food, material and energy supply. Many countries have started to support the use of biomass for biofuels and biomaterials, and, at the same time, are becoming concerned about the increasing consequences of land competition, such as rising food prices, land use change, and land use intensification. Cropland expansion at the cost of tropical forests and savannahs induces severe changes in the living environment with uncertain repercussions. A central question is, thus, to what extent can global cropland expand to serve the growing demand for food and non-food biomass, while keeping the consequences of land use change, such as losses of biodiversity, at a tolerable level? This report explores how the management of land-based biomass production and consumption can be developed towards a higher degree of sustainability across different scales: from the sustainable management of soils on the field to the sustainable management of global land use as a whole. Specifically, this report looks at the impacts of global trends--population growth, urbanization, and changes in diets and consumption behaviors--on global land use dynamics, considering the consequences for biodiversity, the supply of food, fibers and fuel, and the long-lasting implications for resource security. It is intended to support the international discussion and to provide decision makers in national and regional governments and NGOs with an overview of key challenges and possible options related to sustainable land use.

Book Description
This book presents recent estimates on the rate of change of major land classes. Aggregated globally, multiple impacts of local land changes are shown to significantly affect central aspects of Earth System functioning. The book offers innovative developments and applications in the fields of modeling and scenario construction. Conclusions are also drawn about the most pressing implications for the design of appropriate intervention policies.

Book Description
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.

Book Description
The editors of Factor X explore and analyze this trajectory, predicting scarcities of non-renewable materials such as metals, limited availability of ecological capacities and shortages arising from geographic concentrations of materials. They argue that what is needed is a radical change in the ways we use nature’s resources to produce goods and services and generate well-being. The goal of saving our ecosystem demands a prompt and decisive reduction of man-induced material flows. Before 2050, they assert, we must achieve a significant decrease in consumption of resources, in the line with the idea of a factor 10 reduction target. EU-wide and country specific targets must be set, and enforced using strict, accurate measurement of consumption of materials. Their arguments are drawn from empirical evidence and observations, as well as theoretical considerations based on economic modeling and on natural science.

Book Description
This book provides fresh insights into concepts, methods and new research findings on the causes of excessive food price volatility. It also discusses the implications for food security and policy responses to mitigate excessive volatility. The approaches applied by the contributors range from on-the-ground surveys, to panel econometrics and innovative high-frequency time series analysis as well as computational economics methods. It offers policy analysts and decision-makers guidance on dealing with extreme volatility.

Book Description
A history of the unsustainable modern diet—heavy in meat, wheat, and sugar—that requires more land and resources than the planet is able to support. We are facing a world food crisis of unparalleled proportions. Our reliance on unsustainable dietary choices and agricultural systems is causing problems both for human health and the health of our planet. Solutions from lab-grown food to vegan diets to strictly local food consumption are often discussed, but a central question remains: how did we get to this point? In Diet for a Large Planet, Chris Otter goes back to the late eighteenth century in Britain, where the diet heavy in meat, wheat, and sugar was developing. As Britain underwent steady growth, urbanization, industrialization, and economic expansion, the nation altered its food choices, shifting away from locally produced plant-based nutrition. This new diet, rich in animal proteins and refined carbohydrates, made people taller and stronger, but it led to new types of health problems. Its production also relied on far greater acreage than Britain itself, forcing the nation to become more dependent on global resources. Otter shows how this issue expands beyond Britain, looking at the global effects of large agro-food systems that require more resources than our planet can sustain. This comprehensive history helps us understand how the British played a significant role in making red meat, white bread, and sugar the diet of choice—linked to wealth, luxury, and power—and shows how dietary choices connect to the pressing issues of climate change and food supply.
