Description : Winner of the Francis Parkman Prize Changes in the Land offers an original and persuasive interpretation of the changing circumstances in New England's plant and animal communities that occurred with the shift from Indian to European dominance. With the tools of both historian and ecologist, Cronon constructs an interdisciplinary analysis of how the land and the people influenced one another, and how that complex web of relationships shaped New England's communities.

Description : Originally published in Hebrew in 1991, The Changing Land presents a unique aerial view of the changes in Israel's topography from the second decade of the twentieth century to the present. Aerial photographs taken during World War I of Israel by German, British, and Australian aviators, showed the topography of a land fought over for many centuries. Having examined and identified the WWI photographs preserved in German, Australian, Israeli, and British public archives and German private collections, Benjamin Z. Kedar gathered 70 of the photographs to form the book's core. Kedar then collected color aerial photos taken between 1930 and 1990 of the same 70 sites. The result is an unusual and fascinating record of the physical changes in the region during this period of modernization and urban expansion. Changing the Land is more than a topographical view of Israel. Glimpses of the hills, valleys, towns, and villages of Israel provide the reader with a compelling history that words alone cannot describe. This book offers a complete portrait of Israel for anyone who has traveled to the Holy Land or has studied any of its inhabitants.

Description : A changing climate is likely to have a drastic impact on crop yields in Africa. The purpose of this book is to document the effects of climate change on agriculture in Africa and to discuss strategies for adaptation to hotter weather and less predictable rainfall. These strategies include promoting opportunities for farmers to adopt technologies that produce optimal results in terms of crop yield and income under local agro-ecological and socioeconomic conditions. The focus is on sub-Saharan Africa, an area that is already affected by changing patterns of heat and rainfall. Because of the high prevalence of subsistence farming, food insecurity, and extreme poverty in this region, there is a great need for practical adaptation strategies. The book includes empirical research in Ethiopia, Kenya, South Africa, Tanzania, and other Sub-Saharan countries, and the conclusion summarizes policy-relevant findings from the chapters. It is aimed at advanced students, researchers, extension and development practitioners, and officials of government agencies, NGOs, and funding agencies. It also will provide supplementary reading for courses in environment and development and in agricultural economics.

Description : The fed. gov¿t. supports the use of biofuels -- transportation fuels produced from renewable plant matter, such as corn -- in the pursuit of energy, environ., and agr. policy goals. Tax credits (TC) encourage the prod¿n. and sale of biofuels in the U.S., lowering the costs of producing biofuels, such as ethanol or biodiesel, relative to the costs of producing their substitutes -- gasoline and diesel fuel. Fed. mandates require the use of specified minimum amounts and types of biofuel. This study assesses the incentives provided by the TC for producing different types of biofuels and analyzes whether they favor one type of biofuel over others. Estimates the cost to consumers of reducing the use of petroleum fuels and emissions of greenhouse gases through those TC. Illus.

Description : Several environmental changes have occurred in the Sudan in the past; several are ongoing; and others are projected to happen in the future. The Sudan has witnessed increases in temperature, floods, rainfall variability, and concurrent droughts. In a country where agriculture, which is mainly rainfed, is a major contributor to gross domestic product, foreign exchange earnings, and livelihoods, these changes are especially important, requiring measurement and analysis of their impact. This study not only analyzes the economy-wide impacts of climate change, but also consults national policy plans, strategies, and environmental assessments to identify interventions which may mitigate the effects. We feed climate forcing, water demand, and macro-socioeconomic trends into a modelling suite that includes models for global hydrology, river basin management, water stress, and crop growth, all connected to the International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT). The outcomes of this part of the modeling suite are annual crop yields and global food prices under various climate change scenarios until 2050. The effects of such changes on production, consumption, macroeconomic indicators, and income distribution are assessed using a single country dynamic Computable General Equilibrium (CGE) model for the Sudan. Additionally, we introduce yield variability into the CGE model based on stochastic projections of crop yields until 2050. The results of the model simulations reveal that, while the projected mean climate changes bring some good news for the Sudan, extreme negative variability costs the Sudan cumulatively between 2018 and 2050 US$ 109.5 billion in total absorption and US$ 105.5 billion in GDP relative to a historical mean climate scenario without climate change.

Description : This book is based on a Special Issue of the journal LAND that draws together a collection of 11 diverse articles at the nexus of climate change, landscapes, and livelihoods in rural Africa; all explore the links between livelihood and landscape change, including shifts in farming practices and natural resource use and management. The articles, which are all place-based case studies across nine African countries, cover three not necessarily mutually exclusive thematic areas, namely: smallholder farming livelihoods under new climate risk (five articles); long-term dynamics of livelihoods and landscape change and future trajectories (two articles); and natural resource management and governance under a changing climate, spanning forests, woodlands, and rangelands (four articles). The commonalities, key messages, and research gaps across the 11 articles are presented in a synthesis article. All the case studies pointed to the need for an integrated and in-depth understanding of the multiple drivers of landscape and livelihood change and how these interact with local histories, knowledge systems, cultures, complexities, and lived realities. Moreover, where there are interventions (such as new governance systems, REDD+ or climate smart agriculture), it is critical to interrogate what is required to ensure a fair and equitable distribution of emerging benefits.

Description : Forestry has been witness to some dramatic changes in recent years, with several Western countries now moving away from the traditional model of regarding forests merely as sources of wood. Rather these countries are increasingly recognizing their forests as multi-purpose resources with roles which go far beyond simple economics. In this innovative book, Sylvie Nail uses England as a case study to explore the relationships between forests, society and public perceptions, raising important questions about forest policy and management both now and in the future. Adopting a sociological approach to forest policy and management, the book discusses the current validity of the two principles underlying forestry since the Middle Ages: first, that forestry should only exist when no better use of the land can be made, and second, that forestry itself should be profitable. The author stresses how values and perceptions shape policies, and conversely how policies can modify perceptions, and also how policies can fail if they do not take perceptions into account. She concludes that many of the issues facing English forestry in the 21st century – from leisure, health and amenity provision, through education and rural as well as urban regeneration, to biodiversity conservation – go well beyond both national borders and the scope of forestry. Indeed forestry in the 21st century seems to be less about planting and managing trees than about being a vector and a mirror of social change. This novel synthesis provides a valuable resource for advanced students and researchers from all areas of natural resource studies, including those interested in social history, socio-economics, cultural geography and environmental psychology, as well as those studying landscape ecology, environmental history, policy analysis and natural resource management.
