Book Description
Written by leaders in agriculture education, Principles of Agriculture, Food, and Natural Resources is a user-friendly, visual introduction to the systems and concepts that define modern agriculture, including food systems and natural resources. This text is aligned to AFNR standards, providing practical information on building leadership, communication, and career-ready skills while integrating pedagogical tools designed for learner success. Using a modern approach to learning design, information is delivered in smaller sections so students can process and then interact with assessment and review to foster application, analysis, evaluation, and creation. This comprehensive text welcomes today's learners to the diverse and exciting world of agriscience and FFA opportunities, encouraging students to participate in their school, communities, and enroll in advanced courses.

Book Description
"In the seemingly mundane Northern farm of early America and the people who sought to improve its productivity and efficiency, Emily Pawley finds a world rich with innovative practices and marked by a developing interrelationship between scientific knowledge, industrial methods, and capitalism. Agricultural "improvers" became increasingly scientistic, driving tremendous increases in the range and volume of agricultural output-and transforming American conceptions of expertise, success, and exploitation. Pawley's focus on soil, fertilizer, apples, mulberries, agricultural fairs, and experimental stations shows each nominally dull subject to have been an area of intellectual ferment and sharp contestation: mercantile, epistemological, and otherwise"--

Book Description
Intended for aspiring and new practitioners of Participatory Research and Development (PR&D) as well as field-based researchers in developing countries. Highlights that agricultural research and development has become a joint approach to deal with diverse biophysical environments, multiple livelihood goals, rapid changes in local and global economies, and an expanded range for stakeholders over agriculture and natural resources.

Book Description
Harnessing evolution for more sustainable agriculture As human populations grow and resources are depleted, agriculture will need to use land, water, and other resources more efficiently and without sacrificing long-term sustainability. Darwinian Agriculture presents an entirely new approach to these challenges, one that draws on the principles of evolution and natural selection. R. Ford Denison shows how both biotechnology and traditional plant breeding can use Darwinian insights to identify promising routes for crop genetic improvement and avoid costly dead ends. Denison explains why plant traits that have been genetically optimized by individual selection—such as photosynthesis and drought tolerance—are bad candidates for genetic improvement. Traits like plant height and leaf angle, which determine the collective performance of plant communities, offer more room for improvement. Agriculturalists can also benefit from more sophisticated comparisons among natural communities and from the study of wild species in the landscapes where they evolved. Darwinian Agriculture reveals why it is sometimes better to slow or even reverse evolutionary trends when they are inconsistent with our present goals, and how we can glean new ideas from natural selection's marvelous innovations in wild species.

Book Description
For decades, Handbook of Nature Study has been a matchless resource for teachers, naturalists, and anyone curious about the world around them. Originally written in 1911 and later revised by a group of naturalists in 1939, this classic work remains as valid and helpful today as it was back then. Anna Botsford Comstock crafted this handbook primarily for elementary school teachers who had limited knowledge of common plants, animals, and the natural environment. Whether you’re in an urban setting or the rural outback, this treasure trove of information provides insights into the living and nonliving things that surround us.

Book Description
Landscapes are frequently seen as fragments of natural habitat surrounded by a 'sea' of agriculture. But recent ecological theory shows that the nature of these fragments is not nearly as important for conservation as is the nature of the matrix of agriculture that surrounds them. Local extinctions from conservation fragments are inevitable and must be balanced by migrations if massive extinction is to be avoided. High migration rates only occur in what the authors refer to as 'high quality' matrices, which are created by alternative agroecological techniques, as opposed to the industrial monocultural model of agriculture. The authors argue that the only way to promote such high quality matrices is to work with rural social movements. Their ideas are at odds with the major trends of some of the large conservation organizations that emphasize targeted land purchases of protected areas. They argue that recent advances in ecological research make such a general approach anachronistic and call, rather, for solidarity with the small farmers around the world who are currently struggling to attain food sovereignty.Nature's Matrix proposes a radically new approach to the conservation of biodiversity based on recent advances in the science of ecology plus political realities, particularly in the world's tropical regions.
