Spatial Frameworks For Robust Estimation Of Yield Gaps, Juan I. Rattalino Edreira, José F. Andrade, Kenneth G. Cassman, Martin K. Ittersum, Marloes P. Van Loon, Patricio Grassini

Department of Agronomy and Horticulture: Faculty Publications

Food security interventions and policies need reliable estimates of crop production and the scope to enhance production on existing cropland. Here we assess the performance of two widely used ‘top-down’ gridded frameworks (Global Agro-ecological Zones and Agricultural Model Intercomparison and Improvement Project) versus an alternative ‘bottom-up’ approach (Global Yield Gap Atlas). The Global Yield Gap Atlas estimates extra production potential locally for a number of sites representing major breadbaskets and then upscales the results to larger spatial scales. We find that estimates from top-down frameworks are alarmingly unlikely, with estimated potential production being lower than current farm production at some …

Worldwide, ∼196 million are afflicted with endometriosis, a painful disease in which endometrial tissue implants and proliferates on abdominal peritoneal surfaces. Theories on the origin of endometriosis remained inconclusive. Whereas up to 90% of women experience retrograde menstruation, only 10% develop endometriosis, suggesting that factors that alter peritoneal environment might contribute to endometriosis. Herein, we report that whereas some gut bacteria promote endometriosis, others protect against endometriosis by fermenting fiber to produce short-chain fatty acids. Specifically, we found that altered gut microbiota drives endometriotic lesion growth and feces from mice with endometriosis contained less of short-chain fatty acid and n-butyrate …

Palouse Prairie: Ethics Behind The Loss Of An Ecosystem, Hailey V. Smith

Acta Cogitata: An Undergraduate Journal in Philosophy

There is an ethical tradeoff between growing high-yield agricultural products and the integrity and goodness of an ecosystem. Why must we protect an ecosystem and prevent extinction of other organisms? One might claim that the human benefit gained from environmental destructions for the purpose of agriculture is more valuable than any life or structure that existed in the ecosystem. In the case of the Palouse Prairie in Eastern Washington, early white settlers in the area valued the monetary gains from agriculture more than any goodness of an intact ecosystem. Unlike the benefits gained from farming (which could be attained through …

Hegel, Marx, And The Realization Of The Self In Work: Towards A Humanistic Ontology Of Labor, Omar Khali

Acta Cogitata: An Undergraduate Journal in Philosophy

It has become evident in advanced capitalism that the worker’s relation between their labor and their selfhood remains unclear and distorted. For many, labor is merely a means for putting food on the table and a roof over their head. This does not mean, however, that labor in itself gives rise to this prevailing relation. The objective of this essay is to uncover a fundamental ontological characteristic of labor; namely, its ability to reflect one’s subjectivity and capabilities as a human being. I attempt to demonstrate, through thinkers such as Karl Marx and G. W. F. Hegel, that the worker's …
