Evolutionary heuristic to determine future land use

In the spatial electric load forecasting, the future land use determination is one of the most important tasks, and one of the most difficult, because of the stochastic nature of the city growth. This paper proposes a fast and efficient algorithm to find out the future land use for the vacant land in the utility service area, using ideas from knowledge extraction and evolutionary algorithms. The methodology was implemented into a full simulation software for spatial electric load forecasting, showing a high rate of success when the results are compared to information gathered from specialists. The importance of this methodology lies in the reduced set of data needed to perform the task and the simplicity for implementation, which is a great plus for most of the electric utilities without specialized tools for this planning activity. © 2008 IEEE.

Land parceling and neighborhood impacts in Brazil

The proposal and implementation of parceling real estate into smaller lots in Brazil is done according to legal and technical formalities. However, these instruments have proved inefficient in reducing the resulting environmental impacts. The ambiguities of the federal, state and municipal laws and regulations have limited the effectiveness of the actions of urban administrators. Law 10257/2001 emerged as an alternative to overcome these difficulties, proposing the adoption of neighborhood impact studies as an instrument to evaluate new proposals of urban occupation for purposes of environmental licensing. Thus, the purpose of this law is to provide the foundations for municipal public authorities to establish criteria for the assessment, mitigation and compensation of impacts resulting from new occupations. However, the very vagueness of the generic nature of this federal law and its incorrect application in the municipal sphere has posed the greatest obstacles to the good use of this instrument of urban environmental management. These deficiencies are classified herein in the categories of philosophical, technical and operational problems. The problems of a philosophical nature lead to technical difficulties, which in turn trigger operational deficiencies. This article discusses these deficiencies and points out ways to reduce them. © 2009 Journal of Urban and Environmental Engineering (JUEE). All rights reserved.

Proposta de recuperação e manejo de nascente em área rural do município de Álvares Machado – SP

The lack of proper planning in intervention works of runoff water on rural properties and rural public roads leads to economic damage and loss of environmental quality. The impact of the action without technical base is soil erosion, siltation of water sources, loss of the quality and availability of water, invalidating areas for cultivation and livestock. The conservation of headwaters requires beyond regeneration of the environmental characteristics the repair and management of the degraded watercourse in order to control erosion. This graduate work in Environmental Engineering from Universidade Estadual Paulista Julio de Mesquita Filho - UNESP Presidente Prudente proposes a headwater recuperation and management in rural area of Álvares Machado municipality, São Paulo State, through the method of deep drainage applied to the case of a rural road near the outcrop of water. This technique consists in the installation of draining structures in sub-areas of the road surface, or sub-gutter and/or in the platform border in order to conduct the underground flow of water and reduce the loss of sediment in water flow. Therefore, was performed a historic study of use and occupation of land in the municipality of Álvares Machado, portraying transformations of the landscape caused by human action. Geology, geomorphology, pedology and hydrogeology data were collected from the study area in order to establish the conditions that led into the current situation of degradation and formulate an effective intervention strategy for civil works
