Impact of the timing and duration of weed control on the establishment of a rubber tree plantation

A produção da seringueira é reduzida pelas plantas daninhas que competem por recursos ambientais; portanto, a época e duração do controle de plantas daninhas influencia a interferência das plantas daninhas. Os objetivos deste estudo foram: avaliar o crescimento de plantas de seringueira (Hevea brasiliensis), determinar o período crítico para controle das plantas daninhas e avaliar a recuperação do crescimento das seringueiras que conviveram com plantas daninhas por diferentes períodos de tempo após o plantio. Dois grupos de tratamentos foram estabelecidos em condições de campo, no primeiro ano de investigação: um grupo conteve períodos crescentes de infestação de plantas daninhas, enquanto o outro conteve períodos crescentes de controle das plantas daninhas, também incluindo uma testemunha livre de plantas daninhas e uma testemunha com infestação total de plantas daninhas. No segundo ano da investigação, as plantas daninhas foram totalmente controladas. Urochloa decumbens foi a planta daninha dominante (mais de 90% de cobertura). O crescimento da cultura foi grandemente reduzido devido à interferência de plantas daninhas. A altura de plantas decresceu mais rapidamente que qualquer outra característica. Altura de planta, massa seca de folhas e área foliar decresceram em 99%, 97% e 96%, respectivamente, e foram as características mais reduzidas. A altura de plantas também se recuperou mais rapidamente que qualquer outra característica quando o período de controle das plantas daninhas foi entendido. Contudo, a massa seca do caule aumentou em 750%, fazendo desta a característica mais recuperada. O período crítico para o controle de plantas daninhas foi entre 4 e 9½ meses após o plantio, no primeiro ano; contudo, as seringueiras mostraram expressiva recuperação do crescimento quando as plantas daninhas foram controladas ao longo do segundo ano.

Propostas de Adequação Ambiental para a Cidade da Criança de Presidente Prudente - SP

The environmental issue has been considered of fundamental importance for the well being of the present and future generations and is inserted into the commitment of political parties at federal, state and municipal government programs, into the interests of popular organizations and business planning. The Parque Ecológico Cidade da Criança is one of the most sought after places for visitation at Presidente Prudente – SP. Located outside the Raposo Tavares Highway, next to the exhibition grounds and beside the agricultural school, has more than 30 acres of area with an infrastructure designed for recreation and leisure activities for all ages and has received new investment of the public power. Given the importance of the ecological aspects, the objective of this work is to perform an environmental diagnosis in order to be able to submit proposals for solving the problems encountered and improve the use of the environmental resources. Therefore, the study was divided into three foci: sewage disposal, erosion process and control of the stormwater drainage system. It was checked the discharge of sewage from the restaurant on exposed soil, erosion processes that develop at the camel and llama cages ground and erosion processes resulting from the convergence of the stormwater in the highest region of the park. Based on these studies, proposals of solution were made for each case, having considered the effectiveness of the project

Valoração ambiental: síntese dos principais métodos

This study aims to show some methods of environmental assets valuation. These methods are intended to assist in the economic value estimation to environmental resources by the simulation of a hypothetical market, even if there are no market prices related to them. It is about an individual preference measure against the environmental changes. Thus, the environmental valuation methods do not convert a natural resource into a market product. The present report evaluates the applicability of the valuation methods to determine the economic value for assets or resources. The challenge for all is to understand the current economic and ecologic thinking and their limitations, so as to seek improvements in the perception of natural phenomena and in the economic-oriented goal, which is the sustainable development.

Aquaculture Research and Development as an Entry-Point and Contributor to Natural Resources and Coastal Management

Recent, fervent international dialogue concerning the existence and magnitude of impacts associated with aquaculture has had both positive and negative outcomes. Aquaculture stakeholders have become sensitized to requirements for improved environmental management of aquaculture. on the other hand, in some cases aquaculture development has been negatively affected by some of the unwarranted and unproved allegations to the detriment of the stakeholders most in need of aquaculture development (i.e., resource users, particularly the poor, who are dependent on natural resources). These resource users are targeted by, and directly influence biodiversity and conservation agendas; hence the need to understand how to gain their active participation. This discussion focuses on examples of how aquaculture research and development can be a useful tool or strategy for resource management initiatives and provide tangible positive including increased stakeholder participation and cooperation, offering alternatives to resource extraction and use in otherwise difficult or intransigent resource management conflicts.

TERRITORIAL DISPUTES, LABOUR RELATIONS and ENVIRONMENTAL HEALTH IN AGROHIDRONEGOCIO sugarcane IN THE PONTAL PARANAPANEMA (SP)

This research aims to analyze the conflict over land in Postal do Paranapanema (state of São Paulo, Brazil), considering the competition for water resources and the degradation of environmental health in the area called the agrohidronegocio sugarcane. The survey results indicate that the expansion of sugarcane cultivation in this region is causing the worsening health of workers. Moreover, the research also seeks to identify alternative models to the hegemonic project of regional development based on matrix agrohidroenergetica. For this, the research has as interlocutors various types of social movements such as the Landless Workers Movement and the Movement of Dam Affected, and union leaders.

Relationship between green management and environmental training in companies located in Brazil: A theoretical framework and case studies

The main objective of this study is to understand the relationship between green management and environmental training in Brazilian companies, underscoring how this relationship takes place and its most important factors. For such, 9 case studies were conducted at large ISO 14001 certified companies, leaders in their market segments. Several interviews were conducted for each case, documents were collected and visits were made for direct observation. The main contributions and results of this study were: (a) a proposal for a theoretical framework relating the evolutionary stages of green management and the characteristics of environmental training; (b) it was ascertained, as per the proposed theoretical framework, that organizational culture and teamwork, top management support and more technical green management practices are the factors that seem to connect and convert environmental training into more proactive green management, especially for companies in the proactive green management stage; (c) the identification of the co-evolution between the companies' stage of green management and their environmental training level, which is the identified relationship mechanism between environmental training and green management. In other words, the higher the level of adoption of activities recommended for green management, the more evolved the green management practiced at the companies tends to be; and (d) identification that the proposed theoretical framework tends to be useful, mainly because it can explain the relationship between green management and environmental training at the company in the proactive stage.

Integrating geo-referenced multiscale and multidisciplinary data for the management of biodiversity in livestock genetic resources

P>In livestock genetic resource conservation, decision making about conservation priorities is based on the simultaneous analysis of several different criteria that may contribute to long-term sustainable breeding conditions, such as genetic and demographic characteristics, environmental conditions, and role of the breed in the local or regional economy. Here we address methods to integrate different data sets and highlight problems related to interdisciplinary comparisons. Data integration is based on the use of geographic coordinates and Geographic Information Systems (GIS). In addition to technical problems related to projection systems, GIS have to face the challenging issue of the non homogeneous scale of their data sets. We give examples of the successful use of GIS for data integration and examine the risk of obtaining biased results when integrating datasets that have been captured at different scales.
