This text reflects the immense current growth in interest in agroecology and changing approaches to it. While it is acknowledged that the science of ecology should be the basis of agroecological planning, many analysts have out-of-date ideas about contemporary ecology. Ecology has come a long way since the old days of "the balance of nature" and other romantic notions of how ecological systems function. In this context, the new science of complexity has become extremely important in the modern science of ecology. The problem is that it tends to be too mathematical and technical and thus off-putting for the average student of agroecology, especially those new to the subject. Therefore this book seeks to present ideas about ecological complexity with a minimum of formal mathematics. The book’s organization consists of an introductory chapter, and a second chapter providing some of the background to basic ecological topics as they are relevant to agroecosystrems (e.g., soil biology and pest control). The core of the book consists of seven chapters on key intersecting themes of ecological complexity, including issues such as spatial patterns, network theory and tipping points, illustrated by examples from agroecology and agricultural systems from around the world.

Laudato Si' insists on a revolutionary human response to the public challenges of our time concerning the ecological crisis. The volume takes up the revolutionary spirit of Pope Francis and speaks to the economic, technological, political, educational, and religious changes needed to overcome the fragile relationships between humans and Earth. This volume identifies various systemic factors that have produced the anthropogenic ecological crisis that threatens the planet and uses the ethical vision of Laudato Si' to promote practical responses that foster fundamental changes in humanity's relationships with Earth and each other. The essays address not only the immediate behavioral changes needed in individual human lives, but also the deeper, societal changes required if human communities are to live sustainable lives within Earth's integral ecology. Thus, this volume intentionally focuses on a plurality of cultural contexts and proposes solutions to problems encountered in a variety of global contexts. Accordingly, the contributors to this volume are scholars from a breadth of interdisciplinary and cultural backgrounds, each exploring an ethical theme from the encyclical and proposing systemic changes to address deeply entrenched injustices. Collectively, their essays examine the social, political, economic, gender, scientific, technological, educational, and spiritual challenges of our time as these relate to the ecological crisis.

Agroecology is the science of applying ecological concepts and principles to the design, development, and management of sustainable agricultural systems. The Ecology of Agroecosystems highlights a collection of alternative agricultural methodologies and philosophies and provides an interdisciplinary approach that bridges the sociopolitical and historical context of agriculture. It includes the technical issues in a serious and ecological fashion and captures the complex merging of ecology, agriculture, politics and economics in both a historical and contemporary context. Readers will learn not only about the ethical and moral elements related to producing food of questionable quality while possibly impairing the environment, but also about the soil chemistry involved.

Learn how the principles and practices of landscape agroecology can help to overcome drought, flooding, poor soil, damaging winds, plant diseases, plant-eating insects, and more! Examining the concepts, conventions, and components that underlie the ecology of human-managed landscapes, this is the first book to address landscape agroecology. Incorporating ideas from agroecology, forestry, agronomy, agroforestry, landscape ecology, and environmental science, Landscape Agroecology is a comprehensive look at a cutting-edge topic. From the author: “Farm or forestry landscapes can be designed to address any number of objectives. Commonly, the focus is entirely on production with few, if any, secondary goals. These landscapes typically achieve their purpose but are not entirely in harmony with nature. Landscape agroecology offers the same potential for productivity, but also focuses on sustainability and environmental friendliness as strong secondary objectives.” While the idea of formulating landscapes for specific purposes is comparatively new, countless examples exist where landscape modifications have been made to inhospitable areas in order to overcome the natural obstacles that hamper crop growth. This book illuminates the principles behind these triumphs, bringing this local knowledge into the mainstream. Landscape Agroecology will familiarize you with the concepts and terminology needed to understand this exciting new field: complementarity—usually defined in terms of plant-plant growth—expanded to include the rural countryside desirable agroecosystems properties—what an agroecosystem needs in order to overcome landscape stresses such as drought, flooding, insect infestation, etc. agrotechnologies—the classification of agroecosystems based on visual characteristics and the land-use problems addressed cultural agroecology—what we can learn from the superior land-use techniques of various societies and cultures, and how these ideas can be brought into the mainstream cultural motif—culturally related land-use patterns that are openly manifested in the landscape Essential for university/college libraries and for research stations as well as professors and students of agroecology, this book will be referred to again and again. In addition to basic agroecological concepts, chapters in this essential book address the management of wind, water, and pests; biodiversity; physical and temporal patterns; principal, auxiliary, and temporal agrotechnologies, and much more. For professors and students in environmental science, this book offers many previously un-dicussed alternatives for resolving the earth's environmental dilemmas. Photographs, tables, figures, and illustrations help make important points easy to access and understand.

Based on principles of the conservation and optimization of biodiversity and of equity and sustainability, this book focuses on the ecology of the coffee agroecosystem as a model for a sustainable agricultural ecosystem. It draws on the authors' own research conducted over the last twenty years as well as incorporating the vast literature that has been generated on coffee agroecosystems from around the world. The book uses an integrated approach that weaves together various lines of research to understand the ecology of a very diverse tropical agroforestry system. Key concepts explored include biodiversity patterns, metapopulation dynamics and ecological networks. These are all set in a socioeconomic and political framework which relates them to the realities of farmers' livelihoods. The authors provide a novel synthesis that will generate new understanding and can be applied to other examples of sustainable agriculture and food production. This synthesis also explains the ecosystem services provided by the approach, including the economic, fair trade and political aspects surrounding this all-important global commodity.

Agroecology is defined as the application of ecological concepts and principles to the design and management of sustainable food systems. Offering step-by-step guidance for structured investigation, Field and Laboratory Investigations in Agroecology, Second Edition reviews ecological concepts and principles in an agricultural setting and provides in-depth, practical experience. From background information to procedures and suggestions for writing up the results, the book covers 24 different agroecological investigations, each designed to provide all the information needed to plan and execute experimental or comparative studies. It deals with how an individual plant responds to the environment, how environmental factors are measured and characterized, and how environmental factors affect individual plants. The manual investigates how populations of organisms act in agroecosystems, focuses on the level of the community, and explores the between-species interactions of the organisms that make up crop communities. Examining whole farms or systems within farm boundaries, investigations touch on the complexity with which farmers manage agroecosystems. In the last section, the book addresses components of the food system at a local level. Comprising both basic and complex topics, Field and Laboratory Investigations in Agroecology, Second Edition presents a broad scope of issues relevant to agroecology today. This edition facilitates hands-on, experiential learning that involves close observation, creative interpretation, and constant questioning of findings.

Tropical ecosystems are some of the most biologically and ecologically diverse in the world. Traditional, local agroecosystems in the tropics reflect this diversity, and provide excellent examples of how nature can be used as the model for designing and managing sustainable agroecosystems. This book brings together such examples. Using an agroecological approach, the collection of chapters demonstrates how agroecology must simultaneously be a science, a practice, and a movement for social change towards a paradigm of sustainability that engages all parts of the food system, from the field to the table. Chapter contributors were selected from multiple countries and backgrounds, providing a valuable diversity of approaches and knowledge systems, and the interaction of these systems gives this book the important transdisciplinarity that has become a key component of agroecology. Working across disciplines and knowledge systems is necessary in order to link the multiple components of food systems that promote effective change. As food systems return to the diversity, complexity, and resilience they once had, it is collections of experiences as presented in this book that provide examples of the path we must be on. Steve Gliessman, Professor Emeritus of Agroecology, University of California, Santa Cruz, USA.

There is an urgent need to increase agricultural productivity in sub-Saharan Africa in a sustainable and economically-viable manner. Transforming risk-averse smallholders into business-oriented producers that invest in producing surplus food for sale provides a formidable challenge, both from a technological and socio-political perspective. This book addresses the issue of agricultural intensification in the humid highland areas of Africa – regions with relatively good agricultural potential, but where the scarce land resources are increasingly under pressure from the growing population and from climate change. In addition to introductory and synthesis chapters, the book focuses on four themes: system components required for agricultural intensification; the integration of components at the system level; drivers for adoption of technologies towards intensification; and the dissemination of complex knowledge. It provides case studies of improved crop and soil management for staple crops such as cassava and bananas, as well as examples of how the livelihoods of rural people can be improved. The book provides a valuable resource for researchers, development actors, students and policy makers in agricultural systems and economics and in international development. It highlights and addresses key challenges and opportunities that exist for sustainable agricultural intensification in the humid highlands of sub-Saharan Africa.
