Scientists, decision makers, representatives from the productive sector, the State and organized civil society have identified problems, challenges, threats, opportunities as well as conflicts of interest when formulating and implementing the law. Placed in a historical perspective by analyzing the evolution of the Brazilian State and environmental policy, it is acknowledged the need for environmental policies to follow a tendency for cross-disciplinary collaboration and sustainable use of the natural resources and endowment of the country through technical, scientific and traditional knowledge. Often, knowledge is restricted to a simplified thought when formulating environmental policies, and this renders difficult the solid construction of a collective and applicable notion of the widely accepted precept of sustainability. This thesis notes the challenges in reconciling different interests in a political and institutional context with structural problems and conflicts between the different actors involved in formulating and implementing environmental policies concomitant to the existing relationship dynamics between different social actors, public policies and scientific knowledge. In this process, it is crucial to strengthen institutions and knowledge use. The present study seeks to demonstrate that, when formulating environmental policy in Brazil, the existing political and institutional weaknesses prevent the Public Forest Management Law from being implemented effectively for the sustainable and strategic management of Brazilian forests / Doutorado / Aspectos Sociais de Sustentabilidade e Conservação / Doutor em Ambiente e Sociedade

Environmental literacy of workers as a factor in sustainable forest management

Heydenrych, Susan Greville 06 December 2011 (has links)
M.Ed. / Over a period of approximately one hundred years, the South African forestry industry has grown into one of great importance to the national economy with significant international interests. In order to produce a balance of economic efficiency, ecological sustainability and social empowerment to meet the needs of present and future generations, forest resources and associated lands need to be managed effectively. This research aims to investigate and identify trends in the development of sustainable forest management in the South African forest industry. A significant development in recent years has been the emergence of certification. This is intended to ensure sustainable forest management. Certification entails independent and ongoing assessment (auditing) of an organisation's forest management practices, to measure compliance against a range of nationally and internationally recognised social, economic and ecological standards Forestry workers remain largely uneducated and poorly paid and there has been a trend to employ contract labour over the past few years. This research aims to determine the level of environmental literacy of forest workers and to discover to what extent the workers are aware of the problems facing forestry. A combined qualitative and quantitative approach was adopted. The researcher engaged in qualitative observations and open-ended interviews with a number of informants. A quantitative questionnaire was distributed to a sample of forestry workers drawn from three groups. These comprised workers from Komatiland Forestry, Global Forest Products and a group of small independent contractors and sub-contractors. A total of 141 questionnaires were completed and analysed. The results indicated that while forestry practices were generally understood, and correct procedures were followed, a deeper understanding of environmental matters was superficial. The living standards of most of the respondents were found to be poor. This could negatively effect the implementation of sustainable forest development. This research combined a quantitative analysis of the responses to the questionnaire with a qualitative analysis of focused interviews and discussions with various stakeholders in the forestry industry. This provided a broader understanding of the trends in the industry. The forestry industry was found to be in a state of flux. Of the two large companies involved in the research, Global Forest Products had only recently been bought out from Mondi and Komatiland, a state owned forestry company was facing an uncertain future while undergoing the privatisation process. Conditions concerning the workers were generally found to be poor. This was largely due to the companies absolving themselves of social responsibilities. In order to produce a balance of economic efficiency, environmental sustainability and social empowerment a new vision for the forestry industry is needed. This requires the combined efforts of the government, the corporate sector as well as other role players such as labour unions, non-governmental institutions and the general public.

A nucleação como alternativa à restauração passiva e ao reflorestamento com nativas para a restauração florestal /

Trentin, Bruna Elisa, 1992. January 2018 (has links)
Orientador: Vera Lex Engel / Coorientador: Fernando Campanhã Bechara / Banca: Renata Evangelista de Oliveira / Banca: Alessandra dos Santos Penha / Resumo: A escolha do método de restauração, sua implantação, manutenção e monitoramento são fatores de suma importância que devem ser considerados para o cumprimento dos objetivos e o sucesso da restauração ecológica. As técnicas de nucleação surgem como alternativa para a restauração florestal, em uma escala intermediária de grau de intervenção antrópica entre a restauração passiva e o reflorestamento em área total. Entretanto, existe ainda uma carência de estudos sobre nucleação, para que esta técnica seja mais difundida, e que possa ser validada cientificamente. Na busca de avaliar as vantagens de sua utilização em relação a outras técnicas, estudamos a potencialidade da nucleação para a restauração da floresta subtropical, considerando seu papel no controle de invasoras e na promoção da regeneração da vegetação nativa, bem como os custos de sua implantação/manutenção. A área de estudo encontra-se em um ecótono entre a Floresta Ombrófila Mista e a Floresta Estacional Semidecidual, no município de Dois Vizinhos-PR. Os tratamentos foram: (PAS) Restauração passiva; (NUC) Nucleação; e (REF) Reflorestamento com espécies nativas, usando grupos de preenchimento e diversidade. A riqueza de espécies regenerantes foi maior nos tratamentos passiva e nucleação. O custo da nucleação foi 26% menor, quando comparado ao reflorestamento. A nucleação foi mais similar à restauração passiva do que ao reflorestamento, indicando uma maior analogia com processos naturais. Porém, a nucleação não foi efic... (Resumo completo, clicar acesso eletrônico abaixo) / Abstract: Choosing the restoration method, as well as its implementation, maintenance and monitoring are extremely important factors that must be considered for the ecological restoration success. Nucleation techniques appear at an intermediate scale of anthropic intervention between passive restoration and total area reforestation; however, there is still a lack of studies on nucleation, in order to make this technique more widespread and validated scientifically. To evaluate the advantages of nucleation compared to other techniques, we carried out a study of the nucleation potential for subtropical forest restoration, considering its role controlling invasive species and promoting native vegetation regeneration, as well as implementation and maintenance costs. The study site is in a transition of Mixed Ombrophilous Forest to Semideciduous Seasonal Forest, in Dois Vizinhos-PR. The treatments were: (PAS) Passive restoration; (NUC) Nucleation; and (REF) Reforestation with native species, with filling and diversity groups. Regenerating species richness was higher in PAS and NUC treatments. The cost of NUC was 26% lower when compared to REF. NUC was more similar to PAS than REF, indicating a greater analogy with natural processes. However, NUC was not efficient to control invasive species, while REF had lower invasion coverage. A combination of a set of active and passive techniques can enrich in an ecological and economically manner. We recommend mixed designs enriching reforestation with a space destined for passive restoration and where we can even use some isolated nucleation techniques. Nonetheless, in areas with high resilience and without invasion problems, passive ... / Mestre
