Assessing the Spatial Distribution of Crop Production Using a Cross-Entropy Method

Pages : 48
Book Description
While agricultural production statistics are reported on a geopolitical - often national - basis we often need to know the status of production or productivity within specific sub-regions, watersheds, or agro-ecological zones. Such re-aggregations are typically made using expert judgments or simple area-weighting rules. We describe a new, entropy-based approach to making spatially disaggregated assessments of the distribution of crop production. Using this approach tabular crop production statistics are blended judiciously with an array of other secondary data to assess the production of specific crops within individual "pixels" - typically 25 to 100 square kilometers in size. The information utilized includes crop production statistics, farming system characteristics, satellite-derived land cover data, biophysical crop suitability assessments, and population density. An application is presented in which Brazilian state level production statistics are used to generate pixel level crop production data for eight crops. To validate the spatial allocation we aggregated the pixel estimates to obtain synthetic estimates of municipio level production in Brazil, and compared those estimates with actual municipio statistics. The approach produced extremely promising results. We then examined the robustness of these results compared to short-cut approaches to spatializing crop production statistics and showed that, while computationally intensive, the cross-entropy method does provide more reliable estimates of crop production patterns.
Agriculture's Ethical Horizon
Author: Robert L ZimdahlPublisher: Elsevier

Pages : 266
Book Description
What are the goals of agricultural science? What should the goals of agricultural science be? How do and how should the practitioners of agriculture address complex ethical questions? These questions are explored in this monumental book so that those in agriculture will begin an open dialoge on the ethics of agriculture. Discussion of foundational values, of why we practice agriculture as we do, should become a central, rather than peripheral, part of agricultural practice and education. If agricultural scientists do not venture forth to understand and shape the ethical base of the future, it will be imposed by others. Largely autobiographical, this book covers topics such as scientific truth and myth, what agricultural research should be done, an introduction to ethics, moral confidence in agriculture, the relevance of ethics to agriculture, sustainability, and biotechnology. - Written by an expert who has been engaged in agricultural education and research for over 35 years - Content is easily understandable by non-philosophers - The concepts of scientific truth and myth are contrasted and compared - Chapter sidebars highlight important concepts and can be used to engage students in further discussion
