Crop Ecology
Food security and environmental conservation are two of the greatest challenges facing the world today. It is predicted that food production must increase by at least 70% before 2050 to support continued population growth, though the size of the world's agricultural area will remain essentially unchanged. This updated and thoroughly revised second edition provides in-depth coverage of the impact of environmental conditions and management on crops, resource requirements for productivity and effects on soil resources. The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology and morphology. System concepts are explored in detail throughout the book, giving emphasis to quantitative approaches, management strategies and tactics employed by farmers, and associated environmental issues. Drawing on key examples and highlighting the role of science, technology and economic conditions in determining management strategies, this book is suitable for agriculturalists, ecologists and environmental scientists.

Contemplating dis/ability in schools and society
This book chronicles the professional life of a career-long, inclusive educator in New York City through eight different stages in special and general education. Developing a new approach to research as part of qualitative methodology, David J. Connor merges the academic genre of autoethnography with memoir to create a narrative that engages the reader through stories of personal experiences within the professional world that politicized him as an educator. After each chapter’s narrative, a systematic analytic commentary follows that focuses on: teaching and learning in schools and universities; the influence of educational laws; specific models of disability and how influence educators and educational researchers; and educational structures and systems—including their impact on social, political, and cultural experiences of people with disabilities. This autoethnographic memoir documents, over three decades, the relationship between special and general education, the growth of the inclusion movement, and the challenge of special education as a discrete academic field. As part of a national group of critical special educators, Connor describes the growth of counter-theory through the inception and subsequent growth of DSE as a viable academic field, and the importance of rethinking human differences in new ways.

Long-term Effect of Intra-Row Spacing on Growth and Productivity of Super-High Density Hedgerow Olive Orchards (cv. Arbequina)
Intra-row spacing is known to determine early productivity of super-high density olive orchards depending on growing conditions, cultivar growth characteristics, planting geometry and subsequent pruning management but few experiments have been carried out in this olive hedgerow orchard design. In 2008 an experiment of 4-m spaced hedgerows was established with 8 intra-row spacings (from 1.0 to 2.5 m) in Toledo (Spain) resulting in orchards of density ranging from 2,500 to 1,000 trees ha−1. Tree growth was evaluated as height, trunk diameter and leaf area during the first 4 years. Hedgerow porosity was calculated from the 4th until the 9th year. In the 8th year hedgerow height, width, leaf area and branch angles were measured. Olives were harvested from 3rd to 9th year for measurements of fruit characteristics and productivity. Tree growth was not affected by intra-row spacing during the first 4 years. In the 8th year leaf area, external surface area and volume per tree were significantly greater in the more spaced trees; but hedgerow characteristics of leaf area per hectare, number of effective leaf layers horizontally through the hedgerow, and leaf density were not affected. In the more spaced trees insertion angles of branches to the vertical were significantly greater, mainly in the lower canopy. Intra-row spacing did not affect fruit characteristics. Oil production ha−1 decreased linearly with spacing during the first 4 harvests while production per tree increased significantly with spacing after the 3rd harvest. As a result, oil production ha−1 from the seven harvests combined only increased for tree spacing less than 1.2 m; wider spacing had no effect. Annual oil production ha−1 increased linearly as porosity was reduced by greater tree density and canopy development along the seasons.

Disability Critical Race Theory: Exploring the Intersectional Lineage, Emergence, and Potential Futures of DisCrit in Education
In this review, we explore how intersectionality has been engaged with through the lens of disability critical race theory (DisCrit) to produce new knowledge. In this chapter, we (1) trace the intellectual lineage for developing DisCrit, (2) review the body of interdisciplinary scholarship incorporating DisCrit to date, and (3) propose the future trajectories of DisCrit, noting challenges and tensions that have arisen. Providing new opportunities to investigate how patterns of oppression uniquely intersect to target students at the margins of Whiteness and ability, DisCrit has been taken up by scholars to expose and dismantle entrenched inequities in education.

Analysis of farming systems establishes the low productivity of organic agriculture and inadequacy as a global option for food supply
Although generally presented otherwise organic agriculture (OA) is much less productive per unit area of land than conventional agriculture (CA) for two reasons. First, because the yields of individual crops grown in OA are generally less than those in CA. Second, because the reliance in OA on organic fertilizer, i.e. plant and animal manures, requires that additional land grown to legumes to provide nitrogen (N) must be included in the calculation of relative productivity. Compared with the commonly used crop-yield ratios of OA/CA productivity of 0.75–0.81, new analyses of the relative food productivity of various crop- and crop-livestock systems presented here report lower values in the range 0.30–0.74 with many less than 0.5. The OA/CA system ratios are higher in less favourable areas and lower in productive areas more suited to crop intensification. The implications for food security and nature conservation place OA at a disadvantage because transformation to OA would require substantial expansion of agricultural land, e.g. an OA/CA ratio of 0.5, would require a doubling of area under OA to maintain equal production. By contrast, higher yields in CA reduce the demand for land in agriculture and consequently can conserve land for nature.

Response of Oil Production and Quality to Hedgerow Design in Super-High-Density Olive cv. Arbequina Orchards
An analysis is presented of the response of olive oil production and quality parameters, viz. fatty acids (palmitic, oleic and linoleic acids), phenolic compounds and oxidative stability to hedgerow spacing and orientation in 1-m wide super-high-density orchards of cv. Arbequina. Data reveal strong linear relationships between concentrations of fatty acids and internal irradiance within hedgerows, positive for palmitic and linoleic but negative for oleic acid. The result is a significant vertical trend in oil composition within hedgerows, but small to negligible differences in oil harvested from them in totality. The explanation is found in the small ranges and strongly correlated responses of individual fatty acids that together comprise 98% of oil mass. Phenolic compounds respond more widely and to higher levels of irradiance than fatty acids and did show increases in NS hedgerows grown at wide row spacing. Oxidative stability shows a similar trend in phenolic compounds. A simulation study that extended the known responses to 2-m wide hedgerows showed that the linkage between fatty acid profiles was maintained with no resultant differences in the oil composition of the total simulated oil harvest. Based on the current understanding of internal irradiance within olive hedgerows, there seems to be little opportunity to manage oil quality by orchard structure.

Who is Responsible for the Racialized Practices Evident within (Special) Education and What Can Be Done to Change Them?
I pose a straightforward rhetorical question about disproportionality and endeavor to answer it with view to suggesting what can be done in terms of linking theory to practice. First, I frame disproportionality by asking where does it come from? Second, I describe multiple, interconnected historical phenomena to be considered when educators contemplate the complex topic of overrepresentation, ranging from the genesis of historical understandings of human difference becoming categorized into hierarchies of race, to the perceptions of race and dis/ability held by contemporary educators. Third, I argue that connections among these phenomena reified deficit-based understandings of vulnerable children and youth, creating a disabled population that, in turn, continues the status quo of disproportionality within schools. Fourth, invoking the concept of the personal is the professional, I discuss possible actions within an educator's control to help counter overrepresentation, while listing areas outside of school that simultaneously need to be focused upon.

Applying a Critical Disability Studies Lens to Young Adult Literature: Disrupting Ableism in Depictions of Tourette Syndrome
This project is an interdisciplinary endeavor to connect research in the teaching of English with Critical Disability Studies, an intersection that is crucial to disrupting ableism and creating more liberatory schooling and societal contexts that embrace broader notions of human differences. Invoking critical content analysis of five young adult novels that depict characters with Tourette syndrome (TS), we asked, how are various models for understanding “disability” invoked in YA fiction that depicts Tourette syndrome? How do these various models function to reinforce, complicate, or reconstruct in a more progressive way notions about human difference in YA fiction that depicts Tourette syndrome? We focused on one of the many pervasive tropes found within all five novels using the psychodynamic construct of splitting. In particular, we call attention to depictions of TS as embodying an animal—most often a dog—that splits off into the bad/dangerous side, usually subsumed within a character’s “normal self.” This trope can be seen as part of broader, historical discourses that have dehumanized disabled people, constructing them as “other” and subsequently rationalizing exclusionary practices. We advocate for and discuss ways for scholars and educators to continue integrating disability from the margins to the center in literacy research.

Sharing Power With Parents
In this closing commentary to the special edition of Learning Disability Quarterly (LDQ) on parent voice in educational decision making for students with learning disabilities, we briefly survey main topics from each article, illuminating important findings from the authors, along with several questions they raise, and identify themes that reverberate throughout them as a collection. Subsequently, we offer suggestions to improve parental involvement in the decision-making process, in particular, the negotiation of Individualized Education Programs. In doing so, we emphasize the onus placed upon school professionals to better understand parental positionalities and needs, be culturally cognizant and competent in interactions, with the specific purpose of consciously addressing power differentials that have historically inhibited authentic parent–professional relationships. Finally, we end with a short note on the research methodologies used in this special edition.
