“…Roberts (1924) and Sutton (1932) were the first to study the atmospheric dispersion problem. Since then great effort has been devoted to provide analytical solutions to the problem (see, for instance, Arya, 1999, Caputo et al, 2003, and Stockie, 2011. The simplest of these solutions is the Gaussian plume, which has been mainly applied to air pollutants.…”

We build a model to study optimal land use, encompassing land use activities, pollution and climate change. This benchmark set-up allows us to identify the spatial drivers behind the interaction between land use and the environment.Pollution generates local and global damages since it flows across locations following a Gaussian Plume. In contrast to the previous literature on spatial dynamics, we prove that the social optimum problem is well-posed, i.e., the solution exists and is unique. We close the paper with a numerical analysis which illustrates the richness of our model, and its global dynamics. We study the different drivers of spatial heterogeneity. In particular, abatement technology stands out as a fundamental ingredient to achieve steady state solutions, which are compatible with the emergence of spatial patterns.

“…Air parcels pick up spores in source areas and move them into upper-air streams, from which they are eventually deposited at distant locations where the likelihood of infection depends on the presence of a susceptible plant and a favorable environment. Atmospheric dispersion models such as the HYSPLIT4 (for "Hybrid Single-Particle Lagrangian Integrated Trajectory") model are used to calculate the most likely trajectories (28). Use of trajectory analysis in proactive mode is illustrated by the disease warning system for tobacco blue mold, which predicts the seasonal movement of the oomycete pathogen Peronospora tabacina from the Caribbean Basin and the southern United States northward along the east coast of the United States (110).…”

SUMMARY A biological attack on U.S. crops, rangelands, or forests could reduce yield and quality, erode consumer confidence, affect economic health and the environment, and possibly impact human nutrition and international relations. Preparedness for a crop bioterror event requires a strong national security plan that includes steps for microbial forensics and criminal attribution. However, U.S. crop producers, consultants, and agricultural scientists have traditionally focused primarily on strategies for prevention and management of diseases introduced naturally or unintentionally rather than on responding appropriately to an intentional pathogen introduction. We assess currently available information, technologies, and resources that were developed originally to ensure plant health but also could be utilized for postintroduction plant pathogen forensics. Recommendations for prioritization of efforts and resource expenditures needed to enhance our plant pathogen forensics capabilities are presented.

“…AERMET uses three different meteorological data: data of the source location (onsite), data of the offsite location, which is used to complete the onsite meteorological data, and data of the upper air from a location near the source (Caputo et al, 2003).…”

El modelo de dispersión atmosférica de corto alcance (AERMOD, v. 12345) de la Agencia para la Protección Ambiental de Estados Unidos (US-EPA, por sus siglas en inglés) es una buena alternativa para calcular las dosis de radiación que recibe el público general al exterior de instalaciones nucleares, y su avanzada capacidad AERMOD para valorar las descargas atmosféricas rutinarias y accidentales de una nueva planta de energía nuclear (PEN) localizada en Geregu, Nigeria (7º 33' N, 6º 41' W), sobre los cuatro centros urbanos (Ajakuta, Lokoja, Idah y Okene) que se encuentran dentro de la zona delimitada en el plan de emergencia de la PEN. Dicho código ha proporcionado valores para los factores de escala de las concentraciones de radionúclidos utilizaron factores de escala para valorar el posible efecto radiológico externo sobre la biota humana y no humana. Mientras que los efectos radiológicos sobre seres humanos se examinaron mediante los métodos computacionales comunes establecidos por las autoridades regulatorias, respecto de la biota no humana se eligió un enfoque integral para la valoración y manejo de riesgos ambientales debidos a radiación ionizante (D-ERICA). Los resultados de este trabajo indican que, en situaciones de operación normales, la PEN no produce efectos ambientales ni de salud pública importantes. Sin embargo, los accidentes caracterizados por precipitación sí provocarían riesgos radiológicos perceptibles dentro de la zona delimitada en el plan de emergencia de la PEN. ABSTRACTThe United States Environmental Protection Agency (US-EPA) short-range atmospheric dispersion model (AERMOD, v. 12345) is a good candidate for the calculation of offsite radiation doses to the general public, In this paper the AERMOD code has been used to assess the impact of routine and accidental atmospheric radioactive discharges from a new nuclear power plant (NPP) site in Geregu, Nigeria (7˚ 33ˈ N, 6˚ 41ˈ E) on the four major settlements (Ajakuta, Lokoja, Idah and Okene) that lay within the emergency planning zones of the NPP. The code has produced values of the scaling factors for ground level air concentrations and depositions of radionuclides (from the passing plume) over our areas of interest. The scaling factors have been used to assess the potential radiological impact on the offsite human and non-human biota.
