The Brazilian financial system and the green economy : alignment with sustainable development

Three studies were prepared and are presented in this document. The first, The Brazilian Financial Sector Institutional Context in the Transition to Sustainable Development looks at the legislation, regulation, and public policies aimed at socio-environmental themes related to the financial sector. The second study, Current Financing for the Green Economy in Brazil, provides an initial estimate of the financial assets already allocated to the green economy, as well as a methodological proposal for the survey and monitoring of the respective flow of assets. The third and final study looks at two important segments of the Brazilian economy and their process of transition to a greener economy: renewable energy and agriculture.

High performance green buildings

This work aims to study and analyze strategies and measures to improve energy performance in residential and service buildings, in order to minimize energy losses and energy consumption. Due to the high energy dependence of European Union (EU), including Portugal and Slovenia, and high percentage of energy consumption in the building sector, there was a need to adopt strategies at European level with ambitious goals. This came to force EU - Member States to take measures to achieve the proposed targets for energy consumption reduction. To this end, EU - Member States have adapted the laws to their needs and formed specialized agencies and qualified experts on energy certification, which somehow evaluate buildings according to their performance. In this study, the external characteristics of the building in order to meet its thermal needs and from there to survey the existing and possible constructive solutions to be used at the envelope will be examined, in order to increase comfort and reduce the need of use technical means of air conditioning. The possibility of passive heating and ventilation systems also will be discussed. These techniques are developed in parallel with the deployment and design of the building. In this manner, to reduce the energy consumption, various techniques and technologies exploit natural resources. Thus, appear the more sustainable and efficient buildings, so-called Green Buildings have been appeared. The study ends with the identification of measures used in several buildings, proving the economic return in the medium to long term, as well as the satisfaction of their users.

Critical periods of weed control in naturally green colored cotton BRS Verde

Cotton with naturally colored fiber is increasing as a commercial crop due specially to its textile processing with reduced environmental impact, as dying is not necessary. The critical period of weed control and the weed community were studied in a field with the naturally green colored fiber cv. BRS Verde cultivated in Missao Velha, Brazil. Without weed control during all the cycle, a reduction of 82.9% in yield was observed. The critical period of weed control was between 31 and 74 days after emergence for a reduction of 5% in yield. The weed community was composed of 21 species, with higher relative importance and dominance of monocotyledonous species. The beginning of the critical period was found to be more influential on yield than the ending. Thus, defining the right moment to start weed control can be more important to yield than determining the moment to cease it. (C) 2011 Elsevier B.V. All rights reserved.

S-metolachlor efficacy on the control of Brachiaria decumbens, Digitaria horizontalis, and Panicum maximum in mechanically green harvested sugarcane

Objetivou-se com este trabalho avaliar o controle em pré-emergência de Brachiaria decumbens, Digitaria horizontalis e Panicum maximum pelo herbicida S-metolachlor aplicado em pré-emergência em área de cana-de-açúcar colhida mecanicamente sem queima prévia das plantas, com e sem palha sobre o solo. O delineamento experimental foi o de blocos ao acaso, com quatro repetições, em esquema de parcela subdividida 7 x 2. Nas parcelas, foram estudados cinco tratamentos de herbicidas (S-metolachlor a 1,44, 1,92 e 2,40 kg ha-1; clomazone a 1,20 kg ha-1; e isoxaflutole a 0,188 kg ha-1) e duas testemunhas sem aplicação. Nas subparcelas, foi avaliada a manutenção ou não da palha de cana na superfície do solo. A eficácia do herbicida S-metolachlor não foi prejudicada pela presença de 14 ou 20 t ha-1 de palha de cana sobre o solo. Com a manutenção da palha, a dosagem de S-metolachlor para o controle adequado das plantas daninhas foi de 1,44kgha-1. No ambiente sem palha, o S-metolachlor controlou B. decumbens, D. horizontalis e P. maximum nas dosagens de 1.92, 1.44 e 1.92kgha-1, respectivamente. Nas duas condições de palha, os herbicidas clomazone e isoxaflutole foram eficazes para as espécies estudadas. O S-metolachlor não causou nenhum sintoma visível de intoxicação à cana-de-açúcar. O clomazone e o isoxaflutole ocasionaram injúrias visuais às plantas de cana. Os herbicidas estudados não afetaram o número de colmos viáveis por m², a altura e o diâmetro de colmos.
