Acordos de pesca: a efetividade dos acordos para o desenvolvimento local nas comunidades do Pixuna e Jarí do Socorro no município de Santarém-PA

A presente pesquisa propôs-se investigar a efetividade dos acordos de pesca na Amazônia enquanto instrumento de gestão participativa através das populações residentes nas comunidades do Pixuna e Jarí do Socorro no município de Santarém-Pa. Para tanto, analisou-se como as referidas comunidades veem os acordos de pesca vigente, já que as mesmas são consideradas agroextrativistas e que possui na atividade pesqueira sua fonte de renda, proteína e ao longo dos anos vem praticando o mecanismo do acordo de pesca como forma de gestão desta atividade. Também buscou-se entrevistar representantes de ONGs como o IPAM enquanto organização responsável em divulgar de uma maneira mais simples para os pescadores o que vem a ser na forma da Lei e na prática a Instrução Normativa do IBAMA Nº 29/2002 que trata da criação dos acordos de pesca; a Colônia de Pescadores Z-20 representante legal e responsável em defender os interesses e direitos dos trabalhadores do setor artesanal da pesca local perante os órgãos públicos e a sociedade e o IBAMA representante oficial do poder publico, gestor e fiscalizador de quaisquer ações de pesca predatória e de degradação do meio ambiente evidenciados nos acordos implantados nas comunidades. A pesquisa descreve o ambiente de várzea como cenário para essas relações que se estabelecem a partir do uso de um recurso de acesso livre a todos como é o caso do pescado. No que diz respeito à metodologia as técnicas utilizadas se constituíram em: observação direta, aplicação de entrevistas semi-estruturadas e questionários. Foram apresentadas as características da pesquisa, os seus sujeitos e as informações relativas à coleta e à análise dos dados. Assim, o estudo caracterizou-se como qualitativo. Os dados foram analisados através de procedimentos estatísticos básicos com a utilização do software SPSS a partir de frequências e estimativas de parâmetros descritivos, com representação de tendências através de tabelas e gráficos, que tem como finalidade uma melhor visualização destas análises e observações para o contexto da pesquisa. Por fim, foram feitas as considerações finais do estudo, onde foi identificado que a falta de articulação entre os comunitários residentes nas localidades, e das comunidades com o poder publico podem, ser apontados como importantes fatores na decadência observada nos acordos de pesca vigente; outro ponto interessante e de importância considerável é a ausência do órgão responsável pela fiscalização das regras encontradas nos acordos de pesca, o IBAMA. Diante disso, foram sugeridas algumas recomendações aos membros das organizações analisadas.

Dinâmica da produção de serapilheira em diferentes sistemas de restauração florestal

The ecological restoration is an alternative to increasingly important for biodiversity conservation. However, actions need indicators to evaluate its effectiveness in restablishment ecological processes, including nutrient cycling. The objective of this study was to compare the annual litterfall from five different treatments for forest restoration, compared with a neighboring fragment of Seasonal Semideciduous Forest, in order to subsidize their management plans for ecological restoration. Litter traps of 0.25m² were used, and a total production was: 1700.6 Kg. ha-1.year-1(treatment 1), 7748.1 Kg. ha-1.year-1(treatment 2), 7120.8 Kg. ha-1.year-1 (treatment 3), 9254.5 Kg. ha- 1.year-1 (treatment 4), 7130.2 Kg. ha-1.year-1 (treatment 5) and 8876 Kg. ha-1.year-1 (fragment of Seasonal Semideciduous Forest - treatment 6). The leaf fraction was the largest contributor to the deposition of litter in all treatments. Litter served as a good environmental indicator that can be used as a tool to support management plans. Key words: Litterfall, forest restoration and Seasonal Semideciduous Forest

Using landscape metrics to analyze micro-scale soil erosion processes

Methods of recording soil erosion using photographs exist but they are not commonly considered in scientific studies. Digital images may hold an expressive amount of information that can be extracted quickly in different manners. The investigation of several metrics that were initially developed for landscape ecology analysis constitutes one method. In this study we applied a method of landscape metrics to quantify the spatial configuration of surface micro-topography and erosion-related features, in order to generate a possible complementary tool for environmental management. In a 3.7 m wide and 9.7 m long soil box used during a rainfall simulation study, digital images were systematically acquired in four instances: (a) when the soil was dry; (b) after a short duration rain for initial wetting; (c) after the first erosive rain; and (d) after the 2nd erosive rain. Thirteen locations were established in the box and digital photos were taken at these locations with the camera positioned at the same orthogonal distance from the soil surface under the same ambient light intensity. Digital photos were converted into bimodal images and seven landscape metrics were analyzed: percentage of land, number of patches, density of patches, largest patch index, edge density, shape index, and fractal dimension. Digital images were an appropriate tool because they can generate data very quickly. The landscape metrics were sensitive to changes in soil surface micro-morphology especially after the 1st erosive rain event, indicating significant erosional feature development between the initial wetting and first erosive rainfall. The method is considered suitable for spatial patterns of soil micro-topography evolution from rainfall events that bear similarity to landscape scale pattern evolution from eco-hydrological processes. Although much more study is needed for calibrating the landscape metrics at the micro-scale, this study is a step forward in demonstrating the advantages of the method.

Gestão das línguas no século XXI: para uma introdução à política linguística exterior

The objective of this work is to stimulate a debate about the idea of a possible foreign language policy. It seeks to do so from an overview of the structural changes of recent decades - those affecting the economy, information and communication technologies, geopolitics and identities - in order to draw attention to the renewed importance and the role that the language management issues are assuming in this new context. Considering the foreign language policy a theoretical and practical essential tool for the management of language in a globalized world, the focus of the discussion rests on four main aspects: the origins of the notion of foreign language policy; the relationship with the foreign policy of the State; its effectiveness through the intervention on corpus, status and acquisition of the language; and the possibility of their formulation by agents other than the State

THE ROLE OF INDUSTRY IN DEVELOPING NEW MATERIALS FOR VERTEBRATE PEST CONTROL

In the first paper presented to you today by Dr. Spencer, an expert in the Animal Biology field and an official authority at the same time, you heard about the requirements imposed on a chemical in order to pass the different official hurdles before it ever will be accepted as a proven tool in wildlife management. Many characteristics have to be known and highly sophisticated tests have to be run. In many instances the governmental agency maintains its own screening, testing or analytical programs according to standard procedures. It would be impossible, however, for economic and time reasons to work out all the data necessary for themselves. They, therefore, depend largely on the information furnished by the individual industry which naturally has to be established as conscientiously as possible. This, among other things, Dr. Spencer has made very clear; and this is also what makes quite a few headaches for the individual industry, but I am certainly not speaking only for myself in saying that Industry fully realizes this important role in developing materials for vertebrate control and the responsibilities lying in this. This type of work - better to say cooperative work with the official institutions - is, however, only one part and for the most of it, the smallest part of work which Industry pays to the development of compounds for pest control. It actually refers only to those very few compounds which are known to be effective. But how to get to know about their properties in the first place? How does Industry make the selection from the many thousands of compounds synthesized each year? This, by far, creates the biggest problems, at least from the scientific and technical standpoint. Let us rest here for a short while and think about the possible ways of screening and selecting effective compounds. Basically there are two different ways. One is the empirical way of screening as big a number of compounds as possible under the supposition that with the number of incidences the chances for a "hit" increase, too. You can also call this type of approach the statistical or the analytical one, the mass screening of new, mostly unknown candidate materials. This type of testing can only be performed by a producer of many new materials,that means by big industries. It requires a tremendous investment in personnel, time and equipment and is based on highly simplified but indicative test methods, the results of which would have to be reliable and representative for practical purposes. The other extreme is the intellectual way of theorizing effective chemical configurations. Defenders of this method claim to now or later be able to predict biological effectiveness on the basis of the chemical structure or certain groups in it. Certain pre-experience should be necessary, that means knowledge of the importance of certain molecular requirements, then the detection of new and effective complete molecules is a matter of coordination to be performed by smart people or computers. You can also call this method the synthetical or coordinative method.
