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.

Stephen Gliessman's complementary volumes, Agroecology: The Ecology of Sustainable Food Systems, Third Edition and Field and Laboratory Investigations in Agroecology, Third Edition are now available together for one low price. Completely revised, updated, and reworked, the third edition of Agroecology presents new data, material, case studies, and options, as well as more emphasis on topics such as the values, beliefs, and ethics of sustainable food systems. The new edition of Field and Laboratory Investigations in Agroecology facilitates hands-on, experimental learning that involves close observation, creative interpretation, and constant questioning of findings.

Mulberry (Morus spp.) is widely distributed tree taxon found almost in every continent across the globe. Habitat of this plant species is very much diversified, as it is found across all climatic zones ranging from tropical, sub-tropical, temperate, tundra, semi-arid to desert (arid) conditions. It flourishes on all types of landforms; mountains, valleys, plateaus, forests, grasslands, hills, plains and arid lands. Successful utilization of mulberry leaf for silkworm rearing and production of quality cocoons has been studied at length. Now, mulberry is being recognized as a multipurpose plant by most of the countries across the globe. As mulberry is eco-friendly in nature, the propagation of mulberry needs to be done at large scale to address the ecological issues like conversion of arid lands to cultivable lands, eco-restoration of degraded lands, bioremediation of polluted land sites, conservation of water and soil, cleaning the air pollution in urban areas, utilization of mulberry in producing renewable energy in the form of biodiesel. Similarly, there is the need to produce the identified and highly commercially valued pharmaceutical compounds of mulberry under laboratory conditions through in vitro culture based secondary metabolite production through enhanced expression under the stress conditions or in presence of elicitors. Lately protocols have been developed for genetic transformation of mulberry through agrobacterium mediated and particle bombardment mediated gene transfer techniques. Biotechnology based molecular breeding techniques could also be utilized in raising the improved lines through marker assisted selection, soma clonal variations, mutational breeding, somatic hybridization, genome editing and other genetic engineering approaches. Apart from sericulture; mulberry should also be utilized and exploited in other sectors across the globe for additional revenue generation, for livestock maintenance, for environmental safety and in promoting human health. These diversified aspects of mulberry coupled with its economic importance in revenue generation through sericulture, animal husbandry and industrial products has prompted us to prepare this book. It will present a comprehensive account of mulberry plant under 9 chapter headings: introduction, botanical features, ecological features, ecophysiological aspects, interactions and development, molecular aspects, propagation and production, economic importance, and global perspectives as well as future approaches.

This book offers an overview of the most important research and developments in silvopastoral systems of the northern part of South America and Central America, including the most common silvopastoral arrangements in each country and their characteristics in terms of productivity, and environmental and socioeconomic aspects. Featuring a compilation of original research articles, country overviews and reviews of the contribution of silvopastoral systems to different topics, it summarizes the state-of-the-art knowledge regarding various aspects of silvopastoral systems in this region.
