The increased use of chemical fertilizers and pesticides in crop production has adversely affected both the environment and the agricultural economy. Not only has it led to environmental pollution, but also the increasing costs of chemical inputs and the low prices received for agricultural products have contributed to economic unprofitability and instability. The International Symposium on Agricultural Ecology and Environment was organised in order to discuss ways of achieving the goals of economically and environmentally sustainable agriculture. It is apparent that a truly multidisciplinary effort is required and for this reason the meeting was attended by authors from many different disciplines and geographical locations. Although their papers reflect a wide diversity of agroecosystem types and examples, several common themes emerge: the increased importance of biotic control of ecosystem processes in lower input systems; the key role of soil organic matter in stabilizing nutrient cycling; the importance of agricultural landscape diversity and complexity; the importance of studying ecological processes in natural and agricultural ecosystems; the critical need to integrate socio-economic and ecological approaches.

Ecological intensification involves using natural resources such as land, water, soil nutrients, and other biotic and abiotic variables in a sustainable way to achieve high performance and efficiency in agricultural yield with minimal damage to the agroecosystems. With increasing food demand there is high pressure on agricultural systems. The concept of ecological intensification presents the mechanisms of ensuring high agricultural productivity by restoration the soil health and landscape ecosystem services. The approach involves the replacement of anthropogenic inputs with eco-friendly and sustainable alternates. Effective ecological intensification requires an understanding of ecosystems services, ecosystem's components, and flow of resources in the agroecosystems. Also, awareness of land use patterns, socio-economic factors, and needs of the farmer community plays a crucial role. It is therefore essential to understand the interaction of ecosystem constituents within the extensive agricultural landscape. The editors critically examined the status of ecological stress in agroecosystems and address the issue of ecological intensification for natural resources management. Drawing upon research and examples from around the world, the book is offering an up-to-date account, and insight into the approaches that can be put in practice for poly-cropping systems and landscape-scale management to increase the stability of agricultural production systems to achieve ‘Ecological resilience’. It further discusses the role of farmer communities and the importance of their awareness about the issues. This book will be of interest to teachers, researchers, climate change scientists, capacity builders, and policymakers. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, forestry, ecology, agronomy, soil science, and environmental sciences. National and international agricultural scientists, policymakers will also find this to be a useful read for green future.

Rooted firmly in the principles of econology, the agricultural enterprise, even though having been exposed to the impact of environmental problems arising from land degradation, soil erosion, groundwater depletion and pollution and loss of biological diversity, has so far stood firm and survived to meet the food requirements of the growing population, so much so that there have been some striking instances of food glut in several countires, including some that used to sufer famiens only half a century ago.

This textbook applies basic concepts of ecology to address critical issues regarding food and agricultural systems. The intended audience is first year undergraduate students; it may also benefit higher-level undergraduates with an interest in agriculture and ecology. The level of science and general knowledge reflects this target group. The text is divided into five sections with 22 chapters in all. Each chapter has its own student learning objectives. The first two sections, “Context of Agroecology” and “Basics of Agroecosystems,” provide a sound basis for the further study of agriculture from an ecological standpoint. Section 3, “Digging Deeper into Agroecosystems,” explores the related issues of hunger, wastes, climate change, and biodiversity. It is suggested that students study these three sections before proceeding to section 4 or 5. Section 4, “Application of Agroecosystem Concepts,” introduces students to agricultural production and challenges them to use the concepts and ideas from the first three sections to critically evaluate such production systems. Section 5, “Agroecosystem Management,” brings the coverage full circle by examining global solutions and opportunities from both a scientific and social economic standpoint. Particularly these last four chapters offer both food for thought and inspiration for further work. The book’s goal is not to provide a comprehensive literature review; rather, it offers extensive data on and a stimulating analysis of the topic.
Ethics and Sustainable Agriculture

This book describes the alarming condition of agriculture in the Anthropocene, when the ethical conception of agriculture as a service of common utility for both society and environment has progressively been marginalized. The ethical utility of agriculture has been sidetracked with the increasing industrialisation of society, the involvement of agriculture in the business-as-usual economy, and the consequential environmental and societal impacts it has had. Thus, re-establishing a meaningful bridge between ethics and agriculture is necessary. A relatively new science (ecology) with both a new epistemological tool (that of the ecosystem concept), and a unique narrative of sustainable development, can help bridge this gap. This book focuses on ethics as a lever for raising scientific, technical, social, economic and political solutions to adopt in agriculture as a model of symbiotic relationships between man and nature. It provides a detailed discussion of the ecological intensification practices in order to maximize ecological and ethical services, wherein agroecosystems will follow.

The recent technologies for sustainable development and maintaining ecological integrity in the field of agriculture, forestry and environmental management for the green future. Describes the recent technologies and issues to generate awareness among the global scientific community towards sustainable development. Covers various eco-friendly approaches for successful management of soil, water, forest, agriculture, and other natural resources. Addresses the policy issues promoting conservation, protection and management of various natural resources. Presents the issues of climate change and sustainable strategies to combat such a mega event. The existence of life on the earth primarily depends upon the agriculture, forest and environment. The changing climate is imposing the multifaceted challenges in front of human civilization. The agroecosystem management practices and technologies leads to higher productivity with destruction of agricultural, forest and environmental habitat leading to soil-water-air pollution. Food and Agriculture Organization (FAO) plays a key role in the promoting research and developmental activities in various sectors to achieve the sustainable development goals under 2030 agenda. Gradual growth of science and technology has imposed a significant pressure on the different ecosystem. In this context, approaches such as sustainable agriculture, forestry and eco-friendly technologies need to be address across the world. Keeping view of these facts this book underlines scientific chapters dealing with the issues with proper explanation, and accompanied by illustrative diagrams, tables, database as required. The editors have tried to provide a brief scenario about the current issues related to the agriculture, forestry and environment. Therefore, the book would be a very useful resource for academicians, scientists, and policy makers of the related field.

We hear a lot about how agriculture affects climate change and other environmental issues, but we hear little about how these issues affect agriculture. When we look at both sides of the issues, we can develop better solutions for sustainable agriculture without adversely affecting the environment. Agroecology, Ecosystems, and Sustainability explores a modern vision of ecology and agricultural systems, so that crop production can be sustainably developed without further environmental degradation. With contributions from experts from more than 20 countries, the book describes how to make the transition to modern agroecology to help the environment. It examines the global availability of natural resources and how agroecology could allow the world population to reach the goal of global sustainable ecological, agricultural, and food production systems. The book discusses important principles that regulate agroecological systems, including crop production, soil management, and environment preservation. Making the link between theory and practices, the book includes examples of agroecology such as an interdisciplinary framework for the management of integrated production and conservation landscapes and the use of mechanized rain-fed farming and its ecological impact on drylands. An examination of how ecology and agriculture can be allied to ensure food production and security without threatening our environment, the text shows you how natural resources can be used in a manner to create a "symbiosis" to preserve ecological systems and develop agriculture.

Evidence has been mounting for some time that intensive row-crop agriculture as practiced in developed countries may not be environmentally sustainable, with concerns increasingly being raised about climate change, implications for water quantity and quality, and soil degradation. This volume synthesizes two decades of research on the sustainability of temperate, row-crop ecosystems of the Midwestern United States. The overarching hypothesis guiding this work has been that more biologically based management practices could greatly reduce negative impacts while maintaining sufficient productivity to meet demands for food, fiber and fuel, but that roadblocks to their adoption persist because we lack a comprehensive understanding of their benefits and drawbacks. The research behind this book, based at the Kellogg Biological Station (Michigan State University) and conducted under the aegis of the Long-term Ecological Research network, is structured on a foundation of large-scale field experiments that explore alternatives to conventional, chemical-intensive agriculture. Studies have explored the biophysical underpinnings of crop productivity, the interactions of crop ecosystems with the hydrology and biodiversity of the broader landscapes in which they lie, farmers' views about alternative practices, economic valuation of ecosystem services, and global impacts such as greenhouse gas exchanges with the atmosphere. In contrast to most research projects, the long-term design of this research enables identification of slow or delayed processes of change in response to management regimes, and allows examination of responses across a broader range of climatic variability. This volume synthesizes this comprehensive inquiry into the ecology of alternative cropping systems, identifying future steps needed on the path to sustainability.
