Providing the theoretical and conceptual framework for this continually evolving field, Agroecology: The Ecology of Sustainable Food Systems, Second Edition explores environmental factors and complexities affecting agricultural crops and animals. Completely revised, updated, and reworked, the second edition contains new data, new readings, new issues and case studies, and new options. It includes two completely new chapters, one on the role of livestock animals in agroecosystems and one on the cultural and community aspects of sustainable food systems.

The author clearly delineates the importance of using an ecosystem framework for determining if a particular agricultural practice, input, or management decision contributes or detracts from sustainability. He explains how the framework provides the ecological basis for the functioning of the chosen management strategy over the long-term. He also examines system level interactions, stressing the need for understanding the emergent qualities of populations, communities, and ecosystems and their roles in sustainable agriculture. Using examples of farming systems in a broad array of ecological conditions, the book demonstrates how to use an ecosystem approach to design and manage agroecosystems for sustainability.

For weed management most effectively and practically when the weeds are either in the litter or soil as seed, or shortly after the seeds have germinated. Seeds or seedlings in the litter are most likely to be killed by fire, since litter at the surface burns at high temperatures and down to the soil surface. For this reason, it is necessary to have some kind of mulch cover or crop residue to carry the fire. Slash and burn systems are very effective at destroying seed in the litter and on the.

Unnecessary. Such pest resistance is common in domesticated plants, “hiding” in the genome but waiting to be used by plant breeders. As varieties are lost, however, the valuable genetic reservoir of traits is reduced in size, and certain traits potentially invaluable for future breeding are lost forever. There may very well be a soybean variety somewhere in the world resistant to the new soybean rust, but will plant scientists locate it before it goes extinct? Increasing vulnerability to disease.

Fertility management, erosion, unpredictable weather, difficult markets. Paying the bills had to be balanced with ecological practice, and we had lots of time to discuss the potential for combining ecology and agriculture as we returned from market runs to the tropical lowlands over several hours of difficult roads. I gained great respect for Darryl’s wealth of knowledge and vision and am grateful for what he shared with me. During this time, Loma Linda also became a testing ground for some early.

Management, and reduced tillage. featured in the Case Study, is a well-known example of a successful diversified farm operation that has as its centerpiece the use of a modified ridge tillage program (Practical Farmers of Iowa, 2002). The challenge for research on reduced tillage systems is how to find ways to reduce tillage without increasing input costs elsewhere in the system, especially those involving the use of chemicals or fossil fuels. SUSTAINABLE SOIL MANAGEMENT When soil is understood.
