A estrategia de desenvolvimento no II PND: a estrategia industrial.

The objective of the second national development plan was to define industrial expansion in Brazil. The capital goods industry had to be aligned with large infrastructure projects. Also public sector national enterprise was a key element. A newly created financial base 'FIBASE', the national development bank, and state enterprises are principal agents of change in the industrial model. However, the II PND has not succeeded in changing the model because from the beginning it has not considered the realities of the Brazilian economy.-translated by J.Robertson

What are the implications of peri-urban agriculture on food security in Australian cities?

Background: Periurban agriculture refers to agricultural practice occurring in areas with mixed rural and urban features. It is responsible 25% of the total gross value of economic production in Australia, despite only comprising 3% of the land used for agriculture. As populations grows and cities expand, they are constantly absorbing surrounding fringe areas, thus creating a new fringe, further from the city causing the periurban region to constantly shift outwards. Periurban regions are fundamental in the provision of fresh food to city populations and residential (and industrial) expansion taking over agricultural land has been noted as a major worldwide concern. Another major concern around the increase in urbanisation and resultant decrease in periurban agriculture is its potential effect on food security. Food security is the availability or access to nutritionally-adequate, culturally-relevant and safe foods in culturally-appropriate ways. Thus food insecurity occurs when access to or availability of these foods is compromised. There is an important level of connectedness between food security and food production and a decrease in periurban agriculture may have adverse effects on food security. A decrease in local, seasonal produce may result in a decrease in the availability of products and an increase in cost, as food must travel greater distances, incurring extra costs present at the consumer level. Currently, few Australian studies exist examining the change in periurban agriculture over time. Such information may prove useful for future health policy and interventions as well as infrastructure planning. The aim of this study is to investigate changes in periurban agriculture among capital cities of Australia. Methods: We compared data pertaining to selected commodities from the Australian Bureau of Statistics 2000-01 and 2005 -2006 Agricultural Census. This survey is distributed online or via mail on a five-yearly basis to approximately 175,000 Agricultural business to ascertain information on a range of factors, such as types of crops, livestock and land preparation practices. For the purpose of this study we compared the land being used for total crops, and cereal , oil seed, legume, fruit and vegetable crops separately. Data was analysed using repeated measures anova in spss. Results: Overall, total area available for crops in urbanised areas of Australia increased slightly by 1.8%. However, Sydney, Melbourne, Adelaide and Perth experienced decreases in the area available for fruit crops by 11%, 5%,and 4% respectively. Furthermore, Brisbane and Perth experienced decreases in land available for vegetable crops by 28% and 14% respectively. Finally, Sydney, Adelaide and Perth experienced decreases in land available for cereal crops by 10 – 79%. Conclusions: These findings suggest that population increases and consequent urban sprawl may be resulting in a decrease in peri-urban agriculture, specifically for several core food groups including fruit, breads and grain based foods. In doing so, access to or availability of these foods may be limited, and the cost of these foods is likely to increase, which may compromise food insecurity for certain sub-groups of the population.

SIG aplicado na identificação de áreas potenciais aos investimentos habitacionais Estudo de caso: porção oeste do Município do Rio de Janeiro.

A expansão industrial e o desenvolvimento territorial na porção oeste do Município do Rio de Janeiro trazem inúmeras modificações no cenário socioeconômico da região e adjacências. O destaque de investimentos na indústria de transformação é a implantação da Companhia Siderúrgica do Atlântico (CSA), que se mostra como o maior empreendimento privado em realização no país. Investimentos públicos e privados no setor de infraestrutura estão previstos, considerando as características naturais e a localização geográfica privilegiada da região. A influência do porto de Itaguaí e a construção do Arco Metropolitano configuram um corredor de desenvolvimento com reflexos positivos logísticos e socioeconômicos, não só para o estado do Rio de Janeiro, mas também para outros estados brasileiros. Os impactos da reordenação do espaço urbano, com a possibilidade de incremento populacional nas proximidades do novo eixo rodoviário e industrial, tende a gerar um aumento da demanda por serviços no setor terciário. Dessa forma, o planejamento territorial se faz obrigatório, apoiado por geotecnologias. O objetivo da pesquisa foi atender às necessidades do setor habitacional, analisando fatores relevantes e condições favoráveis à implantação de novas construções habitacionais. Baseando-se em dados provenientes do censo do IBGE de 2010 e do Instituto de Urbanismo Pereira Passos (IPP), a Tecnologia da Informação integrada com os dados de mapas digitais e imagens de satélite de alta resolução (World View-2), permitiram uma análise geral do contexto do crescimento regional. Além da análise das variáveis existentes nos dados socioeconômicos, outras variáveis de pesquisa foram empregadas em ambiente SIG, tais como: segurança, proximidades de logradouros principais, existências de escolas e hospitais municipais e estaduais, distância dos centros industriais e de shopping. Após as análises multicriteriais de dados socioeconômicos e bases cartográficas, relatórios na forma de mapas foram emitidos, com a finalidade de orientar o poder público e as construtoras nas tomadas de decisões.

Adsorção de Pb(II) utilizando adsorvente composto por montmorilonita e dolomita

The destructive impact of improper disposal of heavy metals in the environment increases as a direct result of population explosion, urbanization and industrial expansion and technological developments. Argil are potential materials for adsorption of inorganic and the pelletization of it is required for use in adsorptive columns of fixed bed. The low cost and the possibility of regeneration makes these materials attractive for use in the purification process, capable of removing inorganic compounds in contaminated aquatic environments. In this work was made pellets of a mixture of dolomite and montmorillonite by wet agglomeration, in different percentages. The removal of Pb (II) was investigated through experimental studies, and was modeled by kinetic models and isotherms of adsorption. The materials were characterized using the techniques of XRD, TG / DTA, FT-IR, and surface area by BET method. The results showed the adsorption efficiency of the contaminant by the composite material studied in synthetic solution. The study found that the adsorption follows the Langmuir model, and the kinetics of adsorption follows the model of pseudosecond order

Conforto térmico de edificações: análise crítica das tecnologias existentes

The rising in greenhouse gases emission as consequence of industrial expansion especially in developing countries is appointed as one of those reasons responsible for global warming. High-level temperatures are set as responsible for low productivity and high levels of discomfort. With the increase of worldwide energy demand, due to the population growth, this work aims to be an introductory text revising the current ventilation (mechanical and natural) and refrigeration technologies as well as low energy cooling techniques and architectural alternatives that seeks offering good ventilation and ideal buildings temperatures, making them sustainable. In addition, the text deals with the measurement instruments used to evaluate the parameters defined by international and national standards. At last, a case of study applies few concepts and technologies described in the text, introducing the results achieved, the limitations and suggestions to future works

Climate models without pre-industrial volcanic forcing underestimate historical ocean thermal expansion

Episodic explosive volcanic eruptions are a natural part of the climate system but are often omitted from atmosphere-ocean general circulation model (AOGCM) preindustrial spin-up and control experiments. This omission imposes a negative bias on ocean heat uptake in simulations of the historical period. In models of a range of complexity, we find that global-mean sea level rise due to thermal expansion during the last ∼ 150 years is consequently underestimated by 5–30 mm, which is a substantial proportion of the model mean of 50 mm in Coupled Model Intercomparison Project Phase 3 AOGCMs with anthropogenic forcing only, and is therefore important in accounting for 20th century sea level rise. We test and recommend a procedure for removing the bias.

Practice report: the role of environmental factors in industrial site selection activities: a case of limestone quarry expansion in Barbados, West Indies

Site selection is a key activity for quarry expansion to support cement production, and is governed by factors such as resource availability, logistics, costs, and socio-environmental factors. Adequate consideration of all factors facilitates both industrial productivity and sustainable economic growth. This study illustrates the site selection process that was undertaken for the expansion of limestone quarry operations to support cement production in Barbados. First, alternate sites with adequate resources to support a 25-year development horizon were identified. Second, socio-environmental conditions were described and potential impacts identified. Third, a comparative matrix was constructed to evaluate relative site characteristics with respect to physical, ecological, socio-cultural and economic factors. The study shows that environmental factors were essential to the final site recommendation.
