Reflexões sobre o desenvolvimento territorial sustentável, gestão social e cidadania deliberativa: o caso da bacia do rio Almada (BA)

Este artigo tem por objetivo discutir o desenvolvimento territorial sustentável a partir da atuação de diferentes atores sob a ótica da gestão social e o processo de cidadania deliberativa. Analisa-se a construção do "Programa de Manejo Agroambiental da Bacia do Rio Almada" na região pertencente ao território de cidadania Litoral Sul da Bahia. Organizaram-se os dados, as informações e as entrevistas por meio de estudo de caso. Para construção do caso, foi utilizada a triangulação de técnicas da história oral e do sensemaking. O caso em tela contribui para a reflexão sobre os desafios e oportunidades referentes à gestão social, indicando que o processo de cidadania deliberativa pode se constituir em estratégia necessária para o desenvolvimento territorial sustentável. Assim, fica claro que o diálogo, a participação dos atores na elaboração e implantação de políticas públicas é algo complexo, porém imprescindível, quando se almejam transformações das realidades sociais.

Management of Port Solid Waste Framework

One of contemporary environmental issues refers to progressive and diverse generation of solid waste in urban areas or specific, and requires solutions because the traditional methods of treatment and disposal are becoming unviable over the years and, consequently, a significant contingent of these wastes presents final destination inappropriate. The diversity of solid waste generated as a result of human activities must have the appropriate allocation to specific legislation in force, such as landfill, incineration, among other procedures established by the competent bodies. Thus, also the waste generated in port activities or proceeding vessels require classification and segregation for proper disposal later. This article aims at presenting a methodology for the collection, transportation, treatment and disposal of solid waste port and also application of automation technology that makes possible the implementation of the same.

Ordenación territorial, urbanística y de los espacios naturales protegidos y el modelo territorial en la Comunidad Autónoma de Canarias (1982-2009)

[ES] Los graves problemas territoriales existentes en Canarias han motivado un continuo desarrollo normativo autonómico desde los ochenta que culminó con la aprobación en 2000 de un Texto Refundido de las leyes de ordenación del territorio en el que se intentó estructurar jerárquicamente la ordenación territorial, el planeamiento urbanístico y la protección de los espacios naturales. Además de dotarse con instrumentos propios de ordenación, la presente década se ha caracterizado por la definición normativa de un modelo de desarrollo sostenible a través de la formulación de unas Directrices de ordenación. En este artículo abordamos el análisis de las características de la ordenación territorial en Canarias y del modelo de desarrollo promulgado, con el fin de manifestar su escasa capacidad de intervención al mismo tiempo que aportamos una reflexión sobre las nuevas orientaciones anti-cíclicas aprobadas recientemente y que pueden suponer el desmoronamiento de parte del modelo de desarrollo construido en la presente década.

Las unidades ambientales homogéneas como herramienta para la ordenación territorial y la caracterización de litorales áridos

[ES] En Canarias, en las últimas dos décadas se ha generalizado en la actividad de ordenación territorial el empleo de las denominadas unidades de diagnóstico, que fueron reguladas en 1995 por el Decreto 35/95 de Evaluación Ambiental (hoy derogado). Las unidades ambientales homogéneas se han convertido en una herramienta del planificador. La validez de las mismas, los problemas y ventajas que ofrecen en la práctica, es analizada en este artículo de cara a la ordenación y gestión litorales. Desde la praxis se valora la eficacia de esta metodología en las costas orientales de Canarias y su posible extrapolación a otros territorios continentales, comprobando su validez y eficacia en las cercanas costas saharianas y su espacio litoral.

What Happened to Participation? Urban Development and Authoritarian Upgrading in Cairo's Informal Neighbourhoods

Participation appeared in development discourses for the first time in the 1970s, as a generic call for the involvement of the poor in development initiatives. Over the last three decades, the initial perspectives on participation intended as a project method for poverty reduction have evolved into a coherent and articulated theoretical elaboration, in which participation figures among the paraphernalia of good governance promotion: participation has acquired the status of “new orthodoxy”. Nevertheless, the experience of the implementation of participatory approaches in development projects seemed to be in the majority of cases rather disappointing, since the transformative potential of ‘participation in development’ depends on a series of factors in which every project can actually differ from others: the ultimate aim of the approach promoted, its forms and contents and, last but not least, the socio-political context in which the participatory initiative is embedded. In Egypt, the signature of a project agreement between the Arab Republic of Egypt and the Federal Republic of Germany, in 1998, inaugurated a Participatory Urban Management Programme (PUMP) to be implemented in Greater Cairo by the German Technical Cooperation (Deutsche Gesellschaft für Technische Zusammenarbeit, GTZ) and the Ministry of Planning (now Ministry of Local Development) and the Governorates of Giza and Cairo as the main counterparts. Now, ten years after the beginning of the PUMP/PDP and close to its end (December 2010), it is possible to draw some conclusions about the scope, the significance and the effects of the participatory approach adopted by GTZ and appropriated by the Egyptian counterparts in dealing with the issue of informal areas and, more generally, of urban development. Our analysis follows three sets of questions: the first set regards the way ‘participation’ has been interpreted and concretised by PUMP and PDP. The second is about the emancipating potential of the ‘participatory approach’ and its ability to ‘empower’ the ‘marginalised’. The third focuses on one hand on the efficacy of GTZ strategy to lead to an improvement of the delivery service in informal areas (especially in terms of planning and policies), and on the other hand on the potential of GTZ development intervention to trigger an incremental process of ‘democratisation’ from below.

On land management: landowners' attitudes to land and farming in Valdera, Tuscany

This thesis aims at explaining the intersecting dynamics of structural changes in agriculture and urbanisation, which involves changes in urban-rural relationships. The research questions are: how and why do landowners differ in their attitudes to land and farming? what are the main implications on rural landscapes and the policy implications? Relationships between urbanisation and agriculture are firstly analysed through a critical literature review; the analysis focuses on the 'landowner' as the key actor who actively takes decisions on the rural landscape From the empirical study – which is based on a Tuscan area (Valdera), and addressed through qualitative methods – a great diversity of landowners' attitudes to land and farming emerge, thus contributing to the agricultural restructuring, such as: 1) the emphasis on recreational function of the countryside for urban people 2) contracting out of land management, especially when landowners live or/and have 'urban' employment 3) the active role of hobby farmers in land management 4) agricultural operations simplification and lack of investments (especially in case of property rights expropriation). The thesis is framed in three papers, with the same methods and research questions. It seems evident that rural landscapes is subjected to functional changes (e.g. residential) and structural changes (landscape polarisation), which requires the need 1) to consider that rural landscape management is increasingly less connected to agricultural production as economic activity; 2) to give a coherence to the range of policy interventions (physical planning, landscape, sectoral).

Effect of different management intensities on natural and human-induced carbon fluxes in a golf course in northern Italy

Turfgrasses are ubiquitous in urban landscape and their role on carbon (C) cycle is increasing important also due to the considerable footprint related to their management practices. It is crucial to understand the mechanisms driving the C assimilation potential of these terrestrial ecosystems Several approaches have been proposed to assess C dynamics: micro-meteorological methods, small-chamber enclosure system (SC), chrono-sequence approach and various models. Natural and human-induced variables influence turfgrasses C fluxes. Species composition, environmental conditions, site characteristics, former land use and agronomic management are the most important factors considered in literature driving C sequestration potential. At the same time different approaches seem to influence C budget estimates. In order to study the effect of different management intensities on turfgrass, we estimated net ecosystem exchange (NEE) through a SC approach in a hole of a golf course in the province of Verona (Italy) for one year. The SC approach presented several advantages but also limits related to the measurement frequency, timing and duration overtime, and to the methodological errors connected to the measuring system. Daily CO2 fluxes changed according to the intensity of maintenance, likely due to different inputs and disturbances affecting biogeochemical cycles, combined also to the different leaf area index (LAI). The annual cumulative NEE decreased with the increase of the intensity of management. NEE was related to the seasonality of turfgrass, following temperatures and physiological activity. Generally on the growing season CO2 fluxes towards atmosphere exceeded C sequestered. The cumulative NEE showed a system near to a steady state for C dynamics. In the final part greenhouse gases (GHGs) emissions due to fossil fuel consumption for turfgrass upkeep were estimated, pinpointing that turfgrass may result a considerable C source. The C potential of trees and shrubs needs to be considered to obtain a complete budget.

[Acute myocardial infarction: importance of the networking in the initial management]

Early reperfusion with prompt re-establishment of coronary blood flow improves survival in patients suffering from acute ST-elevation myocardial infarction (STEMI). Leaving systemic thrombolysis for primary percutaneous coronary intervention (PCI) is justified by clinical results in favor of PCI. Nevertheless, primary PCI necessitates additional transfer time and requires an efficient territorial networking. The present article summarizes the up-to-dated management of patients with acute STEMI and/or overt cardiogenic shock.

Equations for the Drag Force and Aerodynamic Roughness Length of Urban Areas with Random Building Heights

We use a conceptual model to investigate how randomly varying building heights within a city affect the atmospheric drag forces and the aerodynamic roughness length of the city. The model is based on the assumptions regarding wake spreading and mutual sheltering effects proposed by Raupach (Boundary-Layer Meteorol 60:375-395, 1992). It is applied both to canopies having uniform building heights and to those having the same building density and mean height, but with variability about the mean. For each simulated urban area, a correction is determined, due to height variability, to the shear stress predicted for the uniform building height case. It is found that u (*)/u (*R) , where u (*) is the friction velocity and u (*R) is the friction velocity from the uniform building height case, is expressed well as an algebraic function of lambda and sigma (h) /h (m) , where lambda is the frontal area index, sigma (h) is the standard deviation of the building height, and h (m) is the mean building height. The simulations also resulted in a simple algebraic relation for z (0)/z (0R) as a function of lambda and sigma (h) /h (m) , where z (0) is the aerodynamic roughness length and z (0R) is z (0) found from the original Raupach formulation for a uniform canopy. Model results are in keeping with those of several previous studies.

Comparing remote sensing and ground-based methods of quantifying cover type and carbon storage in an urban forest

Understanding the canopy cover of an urban environment leads to better estimates of carbon storage and more informed management decisions by urban foresters. The most commonly used method for assessing urban forest cover type extent is ground surveys, which can be both timeconsuming and expensive. The analysis of aerial photos is an alternative method that is faster, cheaper, and can cover a larger number of sites, but may be less accurate. The objectives of this paper were (1) to compare three methods of cover type assessment for Los Angeles, CA: handdelineation of aerial photos in ArcMap, supervised classification of aerial photos in ERDAS Imagine, and ground-collected data using the Urban Forest Effects (UFORE) model protocol; (2) to determine how well remote sensing methods estimate carbon storage as predicted by the UFORE model; and (3) to explore the influence of tree diameter and tree density on carbon storage estimates. Four major cover types (bare ground, fine vegetation, coarse vegetation, and impervious surfaces) were determined from 348 plots (0.039 ha each) randomly stratified according to land-use. Hand-delineation was better than supervised classification at predicting ground-based measurements of cover type and UFORE model-predicted carbon storage. Most error in supervised classification resulted from shadow, which was interpreted as unknown cover type. Neither tree diameter or tree density per plot significantly affected the relationship between carbon storage and canopy cover. The efficiency of remote sensing rather than in situ data collection allows urban forest managers the ability to quickly assess a city and plan accordingly while also preserving their often-limited budget.

Predictive control of hybrid vehicle powertrain for intelligent energy management

This thesis studies the minimization of the fuel consumption for a Hybrid Electric Vehicle (HEV) using Model Predictive Control (MPC). The presented MPC – based controller calculates an optimal sequence of control inputs to a hybrid vehicle using the measured plant outputs, the current dynamic states, a system model, system constraints, and an optimization cost function. The MPC controller is developed using Matlab MPC control toolbox. To evaluate the performance of the presented controller, a power-split hybrid vehicle, 2004 Toyota Prius, is selected. The vehicle uses a planetary gear set to combine three power components, an engine, a motor, and a generator, and transfer energy from these components to the vehicle wheels. The planetary gear model is developed based on the Willis’s formula. The dynamic models of the engine, the motor, and the generator, are derived based on their dynamics at the planetary gear. The MPC controller for HEV energy management is validated in the MATLAB/Simulink environment. Both the step response performance (a 0 – 60 mph step input) and the driving cycle tracking performance are evaluated. Two standard driving cycles, Urban Dynamometer Driving Schedule (UDDS) and Highway Fuel Economy Driving Schedule (HWFET), are used in the evaluation tests. For the UDDS and HWFET driving cycles, the simulation results, the fuel consumption and the battery state of charge, using the MPC controller are compared with the simulation results using the original vehicle model in Autonomie. The MPC approach shows the feasibility to improve vehicle performance and minimize fuel consumption.

The Role of Small and Medium-sized Centers for Territorial Development in Switzerland

This paper describes the role of small and medium-sized urban centers in Switzerland. Switzerland is a highly urbanized country where small and medium-sized urban centers play an important role in ensuring a balanced national urban system. Besides the four largest metropolitan regions （Zurich, Geneva, Basel and Bern）, small and medium-sized towns function as central places for a wider, often extensive hinterland. They provide opportunities for living and working and they connect rural and mountain regions to national and international networks. Using secondary statistics and a case study, the paper shows that small and medium-sized urban centers are home to significant concentrations of export-oriented industries. Firms in these value-adding secondary sectors are rooted in these places and benefit from strong local embeddedness while also being oriented towards global markets. Small and medium-sized urban centers also profit from their strong local identities. While these places face various challenges, they function as important pillars in creating a balanced regional development pattern. Swiss regional development policy follows the goal of polycentric spatial development and it employs various instruments that aim to ensure a balanced urban system.

A survey of paediatric HIV programmatic and clinical management practices in Asia and sub-Saharan Africa--the International epidemiologic Databases to Evaluate AIDS (IeDEA)

INTRODUCTION There are limited data on paediatric HIV care and treatment programmes in low-resource settings. METHODS A standardized survey was completed by International epidemiologic Databases to Evaluate AIDS paediatric cohort sites in the regions of Asia-Pacific (AP), Central Africa (CA), East Africa (EA), Southern Africa (SA) and West Africa (WA) to understand operational resource availability and paediatric management practices. Data were collected through January 2010 using a secure, web-based software program (REDCap). RESULTS A total of 64,552 children were under care at 63 clinics (AP, N=10; CA, N=4; EA, N=29; SA, N=10; WA, N=10). Most were in urban settings (N=41, 65%) and received funding from governments (N=51, 81%), PEPFAR (N=34, 54%), and/or the Global Fund (N=15, 24%). The majority were combined adult-paediatric clinics (N=36, 57%). Prevention of mother-to-child transmission was integrated at 35 (56%) sites; 89% (N=56) had access to DNA PCR for infant diagnosis. African (N=40/53) but not Asian sites recommended exclusive breastfeeding up until 4-6 months. Regular laboratory monitoring included CD4 (N=60, 95%), and viral load (N=24, 38%). Although 42 (67%) sites had the ability to conduct acid-fast bacilli (AFB) smears, 23 (37%) sites could conduct AFB cultures and 18 (29%) sites could conduct tuberculosis drug susceptibility testing. Loss to follow-up was defined as >3 months of lost contact for 25 (40%) sites, >6 months for 27 sites (43%) and >12 months for 6 sites (10%). Telephone calls (N=52, 83%) and outreach worker home visits to trace children lost to follow-up (N=45, 71%) were common. CONCLUSIONS In general, there was a high level of patient and laboratory monitoring within this multiregional paediatric cohort consortium that will facilitate detailed observational research studies. Practices will continue to be monitored as the WHO/UNAIDS Treatment 2.0 framework is implemented.
