Proposta metodológica de inclusão da gestão de análises de riscos naturais no zoneamento ecológico e econômico

A região da Calha Norte, localizada no Baixo Amazonas do Estado do Pará, sofre historicamente com vários tipos de ameaças naturais, como cheias, enchentes, alagamentos, erosão, estiagem, enxurrada, fortes chuvas e secas, todas registradas pela Defesa Civil. Todos os anos, seja no período da chuva ou no período da seca, a população fica vulnerável a tais eventos. A presente dissertação consiste em adaptar uma iniciativa metodológica que permita a incorporação da temática de gestão de riscos naturais no Zoneamento Ecológico Econômico (ZEE) do Brasil, tendo como estudo de caso o ZEE da Calha Norte do Pará, proporcionando instrumentos para a gestão e melhorias das ações do poder público. A análise das ameaças naturais baseou-se em estudo metodológico que agregou dados históricos, mapa geomorfológico, mapa geológico, mapa hipsométrico, mapa de declividade, identificando as três classes de análises: (i) área de alta suscetibilidade; (ii) área de moderada suscetibilidade e (iii) área de baixa suscetibilidade, gerando assim os mapas das ameaças de inundação, de erosões e das secas. A construção da vulnerabilidade social ocorreu a partir da aplicação do Índice de Vulnerabilidade Social (IVS) e do Índice de Unidades de Resposta (IUR), oriundos dos dados do Censo 2010 e do Cadastro Nacional de Endereço para Fins Estatísticos (CNEFE), ambos do IBGE. Após a aplicação de tais índices verificou-se que, do total de 397 setores censitários da área de estudo, 365 setores apresentam alta vulnerabilidade e os demais, moderada e baixa vulnerabilidade, o que retrata grande preocupação com tal área. Na análise de risco, os dados de vulnerabilidade e ameaças foram integrados e novamente classificados em três níveis: (i) alto risco, onde há pouca concentração de unidades de respostas e são áreas de alta ameaça, podendo provocar danos sociais e econômicos quando e se ocorrerem as ameaças naturais; (ii) médio nível de risco, resultado gerado do cruzamento de áreas de altas ameaças x baixas ameaças e (iii) baixo nível de risco, resultando em dois produtos cartográficos: o mapa de risco de inundação e o mapa de risco de erosão. O ZEE da Calha Norte do Pará foi analisado com alguns questionamentos a fim de verificar a inclusão da temática de ameaça, vulnerabilidade e risco no documento, concluindo-se pela falta desta no documento técnico. Além disto, os resultados obtidos com a pesquisa são de elevada importância no sentido de subsidiar o ordenamento territorial e também para a criação de políticas públicas para a região.

Optimization of the sampling scheme for maps of physical and chemical properties estimated by kriging

The sampling scheme is essential in the investigation of the spatial variability of soil properties in Soil Science studies. The high costs of sampling schemes optimized with additional sampling points for each physical and chemical soil property, prevent their use in precision agriculture. The purpose of this study was to obtain an optimal sampling scheme for physical and chemical property sets and investigate its effect on the quality of soil sampling. Soil was sampled on a 42-ha area, with 206 geo-referenced points arranged in a regular grid spaced 50 m from each other, in a depth range of 0.00-0.20 m. In order to obtain an optimal sampling scheme for every physical and chemical property, a sample grid, a medium-scale variogram and the extended Spatial Simulated Annealing (SSA) method were used to minimize kriging variance. The optimization procedure was validated by constructing maps of relative improvement comparing the sample configuration before and after the process. A greater concentration of recommended points in specific areas (NW-SE direction) was observed, which also reflects a greater estimate variance at these locations. The addition of optimal samples, for specific regions, increased the accuracy up to 2 % for chemical and 1 % for physical properties. The use of a sample grid and medium-scale variogram, as previous information for the conception of additional sampling schemes, was very promising to determine the locations of these additional points for all physical and chemical soil properties, enhancing the accuracy of kriging estimates of the physical-chemical properties.

Consolidation of the genetic and cytogenetic maps of turbot (Scophthalmus maximus) using FISH with BAC clones

Bacterial artificial chromosomes (BAC) have been widely used for fluorescence in situ hybridization (FISH) mapping of chromosome landmarks in different organisms, including a few in teleosts. In this study, we used BAC-FISH to consolidate the previous genetic and cytogenetic maps of the turbot (Scophthalmus maximus), a commercially important pleuronectiform. The maps consisted of 24 linkage groups (LGs) but only 22 chromosomes. All turbot LGs were assigned to specific chromosomes using BAC probes obtained from a turbot 5x genomic BAC library. It consisted of 46,080 clones with inserts of at least 100 kb and < 5 % empty vectors. These BAC probes contained gene-derived or anonymous markers, most of them linked to quantitative trait loci (QTL) related to productive traits. BAC clones were mapped by FISH to unique marker-specific chromosomal positions, which showed a notable concordance with previous genetic mapping data. The two metacentric pairs were cytogenetically assigned to LG2 and LG16, and the nucleolar organizer region (NOR)-bearing pair was assigned to LG15. Double-color FISH assays enabled the consolidation of the turbot genetic map into 22 linkage groups by merging LG8 with LG18 and LG21 with LG24. In this work, a first-generation probe panel of BAC clones anchored to the turbot linkage and cytogenetical map was developed. It is a useful tool for chromosome traceability in turbot, but also relevant in the context of pleuronectiform karyotypes, which often show small hardly identifiable chromosomes. This panel will also be valuable for further integrative genomics of turbot within Pleuronectiformes and teleosts, especially for fine QTL mapping for aquaculture traits, comparative genomics, and whole-genome assembly.

Relaxation to Fixed Points in the Logistic and Cubic Maps: Analytical and Numerical Investigation

Convergence to a period one fixed point is investigated for both logistic and cubic maps. For the logistic map the relaxation to the fixed point is considered near a transcritical bifurcation while for the cubic map it is near a pitchfork bifurcation. We confirmed that the convergence to the fixed point in both logistic and cubic maps for a region close to the fixed point goes exponentially fast to the fixed point and with a relaxation time described by a power law of exponent -1. At the bifurcation point, the exponent is not universal and depends on the type of the bifurcation as well as on the nonlinearity of the map.

The lack of environment planning studies in Brazil drives to an imbalance due to a disorderly occupation in some areas. As the youngest Brazilian state facing a fast occupation, Tocantins is included on this situation. In order to provide guidelines for an environment planning studies, this paper is under geoenvironmental zoning which is based on the integration of physical aspects. This detailed study supported by maps elaborated on GIS environment, will be able to present the support for planning studies focused on the potential or limitation of the area

Zoneamento geoambiental como instrumento de planejamento e gestão de recursos do pólo cerâmico de Santa Gertrudes

The disorded and unnplaned occupation is not recent in out territory but it concerns to a historical territorial invasion that roots the time of our country discovery. However, they have started to cause issues nowadays, as in the case of urban conurbations. Somehow these unorganized urban, industrial and agricultural occupations did not have any sort of information or indication of the appropriate situation at that time. Because of that there has been researches by several groups to induce the users of the several renewable and non renewable resources to explore them according to their natural potential capacity.The Ceramic Pole of Santa Gertrudes, the national largest producer of ceramic tile, faces this problem of disorder occupation. Among other themes, the reorganization of the physical environment, proposed by several groups of researchers and scholars of this subject, is gaining attention now.The method of Geoenvironmental Zoning results in a way of prevention from this issue. Crossing information of the physical environment and generating maps whose areas and subdivisions have similar characteristics, it is possible to manage studies and handle these areas according to their potentiality.
