Concepção e Implementação de um Sistema de Controle de Arborização Urbana através da Integração de Softwares Livres e de Código Aberto

Suitable computacional tools allow to build applications that can link information to its physical location, and represent them into visual and interactive schemes, e ectively reaching the power of visual comunication. This leads the user to synthesize information in a simple and e cient way. These applications are linked to the de nition of Geographic Information System (GIS). GIS are comprised by many concepts and tools, which have the main purpose of collecting, storing, viewing and processing spatial data, obtaining the information needed for decision making. Within this context, this paper presents the Conception and Implementation of a Control System for Urban Forestry through Integration of Free and Open Source Software. This conception arose from the need of an Environmental Project developed by the Agriculture's House of the city of Regente Feij o, which has as main objectives cataloging and management of urban a orestation of the municipality. Due to this diversity of concepts, the challenge in building this system is the integration of platforms that are involved in all stages: collecting and storage of data, including maps and other spatial information, operations on the stored information, obtaining results and graphical visualization of the same. After implementation, it was possible to provide for the system users an improvement in the capacity of perception in the information analysis and facilitate the process of decision making

The massive urbanization and activities arising from the uncontrolled growth of urban areas, result in changes on the climate, making it unhealthy. One factor that contributes to poor quality of life due to this fact is the islands of heat that consists in the accumulation of surface heat and raises the temperature in the cities. The vegetation consists of urban greening, urban forests and green areas, have the function to minimize this effect. To reconcile these factors, collected data on surface temperature by satellite images, LANDSAT 5 captured on 18/12/2012 point 75 e 76, orbits 221, band 6 and on-site survey with thermo-hygrometer, possessed the data, crossing the conducted vegetative survey and provided a management vision to improve the microclimate of the city under study. The vegetation coverage at urban area directly affects the ambient temperature, improving the urban micro-climate. The different analyzed surface coverage also affects the apparent temperature. Among the studied ranks, the eucalyptus cultivation, native forest, urban area and solo exposed areas with greater vegetation cover have mild temperatures and improved microclimate.

Novel techniques for the remote sensing of photosynthetic processes

Remote sensing (RS) techniques have evolved into an important instrument to investigate forest function. New methods based on the remote detection of leaf biochemistry and photosynthesis are being developed and applied in pilot studies from airborne and satellite platforms (PRI, solar-induced fluorescence; N and chlorophyll content). Non-destructive monitoring methods, a direct application of RS studies, are also proving increasingly attractive for the determination of stress conditions or nutrient deficiencies not only in research but also in agronomy, horticulture and urban forestry (proximal RS). In this work I will focus on some novel techniques recently developed for the estimation of photochemistry and photosynthetic rates based (i) on the proximal measurement of steady-state chlorophyll fluorescence yield, or (ii) the remote sensing of changes in hyperspectral leaf reflectance, associated to xanthophyll de-epoxydation and energy partitioning, which is closely coupled to leaf photochemistry and photosynthesis. I will also present and describe a mathematical model of leaf steady-state fluorescence and photosynthesis recently developed in our group. Two different species were used in the experiments: Arbutus unedo, a schlerophyllous Mediterranean species, and Populus euroamericana, a broad leaf deciduous tree widely used in plantation forestry. Results show that ambient fluorescence could provide a useful tool for testing photosynthetic processes from a distance. These results confirm also the photosynthetic reflectance index (PRI) as an efficient remote sensing reflectance index estimating short-term changes in photochemical efficiency as well as long-term changes in leaf biochemistry. The study also demonstrated that RS techniques could provide a fast and reliable method to estimate photosynthetic pigment content and total nitrogen, beside assessing the state of photochemical process in our plants’ leaves in the field. This could have important practical applications for the management of plant cultivation systems, for the estimation of the nutrient requirements of our plants for optimal growth.

Respuesta al déficit hídrico en el crecimiento de forestales del bosque urbano de Mendoza : análisis comparativo en árboles jóvenes

El objetivo del trabajo fue evaluar la respuesta de plantas jóvenes de cuatro especies forestales urbanas a diferentes niveles de déficit hídrico. El ensayo se realizó en vivero, durante tres ciclos vegetativos, con plantas de Platanus x hispanica cv. acerifolia (plátano), Morus alba (morera), Fraxinus americana (fresno americano) y Acacia visco (visco). Los tratamientos de riego fueron: control (reposición del 100% transpirado); riego deficitario moderado (reposición del 66% transpirado) y riego deficitario severo (reposición del 33% transpirado). Las variables de respuesta evaluadas fueron altura, diámetro de tallos, área foliar y ancho de anillos de crecimiento. Las plantas bajo riego deficitario severo presentaron disminuciones en todos los parámetros de crecimiento considerados. Acacia visco resultó con crecimientos comparables al control, bajo riego deficitario equivalente al 66% del agua transpirada, con lo cual puede ser considerada especie de interés para forestaciones en condiciones de estrés hídrico moderado.

Bath, Inc. Landfill : Macon County, Illinois.

The 17-acre landfill southwest of Decatur on the south bank of the Sangamon River was permitted in 1974 as a demolition debris landfill. It originated as an open dump in 1918. The site had a history of not complying with the state landfill rules in the 1980s. The landfill also exceeded its permitted waste disposal limits, by the time that the operations stopped in 1991. The owner failed to comply with an August 1994 court order requiring proper cover to be installed and maintained. Visible leachate seeps (leachate is water that has traveled through the landfill and contacts waste material) and exposed refuse were observed along the bank of the Sangamon River. ... This landfill was one of the 33 landfills in Illinois identified by the Illinois EPA in 1998 as most in need of immediate repairs. The state legislature responded by passing legislation that allocated $50 million over five years to address these 33 sites. These 33 landfills are being managed through the Abandoned Landfill Program.

Opportunity Returns : Southern Region.

Opportunity Returns is Governor Blagojevich's comprehensive plan for restoring economic opportunity to Illinois -- an approach designed to create jobs and spur growth. This is a new approach to economic development in Illinois that focuses the state's resources on the specific strengths and needs of each region -- recognizing that local communities understand their strengths and needs the best. Ten regional plans have been developed to fit each of the regions. This plan outlines economic goals for the Southern region, which consists of Alexander, Edwards, Franklin, Gallatin, Hamilton, Hardin, Jackson, Jefferson, Johnson, Massac, Perry, Pope, Pulaski, Saline, Union, Wabash, Wayne, White, and Williamson counties.
