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.
