Environment and Society connects the core themes of environmental studies to the urgent issues and debates of the twenty-first century. In an era marked by climate change, rapid urbanization, and resource scarcity, environmental studies has emerged as a crucial arena of study. Assembling canonical and contemporary texts, this volume presents a systematic survey of concepts and issues central to the environment in society, such as: social mobilization on behalf of environmental objectives; the relationships between human population, economic growth and stresses on the planet’s natural resources; debates about the relative effects of collective and individual action; and unequal distribution of the social costs of environmental degradation. Organized around key themes, with each section featuring questions for debate and suggestions for further reading, the book introduces students to the history of environmental studies, and demonstrates how the field’s interdisciplinary approach uniquely engages the essential issues of the present.

The World population will reach 9 billion by 2050, with the majority of this growth occurring in developing countries. On the other hand, one in nine of the World's population suffers from chronic hunger, the vast majority of which live in developing countries. We therefore need to find new and sustainable solutions to feed this increasing population and alleviate the predicted negative impact of global changes on crop production. This e-Book deals with new strategies to improve food security and livelihoods in rural communities, reduce vulnerability, increase resilience and mitigate lthe impact of climate change and land degradation on agriculture. This collection of 18 articles addresses the major abiotic factors limiting crop production worldwide, how to characterize and exploit the available plant biodiversity to increase production and sustainability in agrosystems, and the use of beneficial microbes to improve production and reduce the use of fertilizers and pesticides.

The improvement of crop species has been a basic pursuit since cultivation began thousands of years ago. To feed an ever increasing world population will require a great increase in food production. Wheat, corn, rice, potato and few others are expected to lead as the most important crops in the world. Enormous efforts are made all over the world to document as well as use these resources. Everybody knows that the introgression of genes in wheat provided the foundation for the “Green Revolution”. Later also demonstrated the great impact that genetic resources have on production. Several factors are contributing to high plant performance under different environmental conditions, therefore an effective and complementary use of all available technological tools and resources is needed to meet the challenge.

Agricultural research and development have profoundly increased the quantity and quality of food production in the twentieth century. As populations increase, however, and land and water resources become more scarce, we must improve productivity and efficiency to provide adequate food supplies. Issues such as the environment, genetic diversity, food safety, poverty, human health, animal rights, public versus private responsibilities, and the question of intellectual property rights further complicate this task. Agricultural Science Policy: Changing Global Agendas consists of twelve chapters that describe important issues in agricultural science policy, the relevant facts, current economic thinking, and new results. Topics Include: Changing Global Contexts and Agendas for Agricultural R & D; Productivity Measures and Measurement; Research, Productivity, and Natural Resources; Research for Genetic Improvement; and a Conclusion, which suggests directions for the future. The chapters in this volume will provide researchers and policy makers with a timely review of progress on the existing agenda as well as laying the foundation for a new agenda and new directions for global agricultural science policy in the 21st century.
