Nature Protection Areas (NPA) are important in the modern world, although still created with no well-defined criteria, overall in state and municipal spheres. In addition, there are no consistent information on the existence or factors that influence the creation and distribution of these areas. The present work had the objectives of identifying the Nature Protection Areas in Minas Gerais, Brazil, considering the municipalities and their mesoregions; perform a space-temporal analysis of the NPAs in Minas Gerais; relate the existence of NPAs with the Municipal Human Development Index (MHDI) and the municipal Gini Index (GI); relate the existence of NPA with the space-temporal and population density of each municipality; relate the Gross Domestic Product (GDP) with the presence of NPAs; relate the existence of NPAs with the occurrence of preservation areas in municipalities within the Atlantic Forest Biome; and verify the influence of the Ecological Sales and Services Tax (Ecological ICMS) institute over the creation of municipal NPAs in Minas Gerais. To reach these objectives, we researched databases, governmental websites, contacted managers and sent questionnaires to the 853 municipalities of Minas Gerais. After tabulating the data, statistical tests were applied to verify possible correlations. The results showed that the state has 9.26% of its territory protected, with the predominance of units of Sustainable Use, especially Environmental Protection Areas, which constitute 69.9% of this area. Only 1.96% of the territory are protected by Integral Protection (IP). We found no correlation between MHDI and the presence of NPAs. However, we verified that municipalities with IP units present higher GI when compared to the others, suggesting that the presence of this conservation unit (CU) model may be associated to social inequality. The results also showed a higher concentration CU in regions that use little of its natural resources as main economic basis and in municipalities with higher GDP. We also registered a positive correlation between the size of the municipalities, of the mesoregions, preserved area of the Atlantic Forest and population density. The Ecological ICMS did not contribute for a better IP in the state and, currently, does not represent an incentive to the creation of CU in Minas Gerais, even in the case of Environmental Protection Areas. This work registered a high degree of vulnerability if the protection system in this state, based on low restriction conservation units.

A ocupação inconsequente do território e a aplicação de técnicas agropastoris altamente degradantes ao meio ambiente, no Estado de São Paulo, culminaram em uma diminuição da cobertura vegetal nativa preservada de apenas 14% da cobertura original. Nesse cenário, o Novo Código Florestal, de 1964, regulamentava a proteção das chamadas Áreas de Preservação Permanente e a aplicação da área de Reserva Legal, que consistia em uma porcentagem da área total da propriedade rural destinada à preservação para a manutenção da biodiversidade local. Com a função de guiar as propostas de recuperação das áreas degradadas e de preservação dos remanescentes nativos, um Programa de Adequação Ambiental foi desenvolvido no presente estudo. Seu objetivo é adequar uma pequena propriedade rural, localizada no município de São Carlos – SP, às leis ambientais, com a finalidade de torná-la o mais ecologicamente sustentável possível. Com o auxilio de imagens de satélite disponíveis gratuitamente na internet e programas de SIG (ArcGis, Stitch Maps), o Programa de Adequação Ambiental da Estância 4R avaliou os usos e ocupações da propriedade, indicando que mais da metade da propriedade (35 ha) são destinados à criação de gado de corte e quase todo o restante (20 ha) está arrendado para o cultivo de cana-de-açúcar, e sugeriu propostas de restauração da área de Reserva Legal, cuja área deve ser de 12 ha, bem como sua localização, ao sul da propriedade. Como ação de restauração, foi proposto o consórcio de espécies arbóreas nativas com linhas de plantio de café de sombra, em um sistema de plantio conhecido como Agroflorestal

The spatial chaotic urban growth is an increasing and common problem in Brazilian cities, especially in the State of São Paulo. In order to assist the territorial expansion planning, the present study aimed to conduct the environmental diagnosis of urban expansion areas in the City of Jaguariúna – SP, bounded by the Municipal Plan. From the preparation and analysis of thematic maps, literature review and field analysis, data were collected for use and occupation, geology, geomorphology, pedology, vegetation, water resources and features surrounding the five urban sprawl existing areas. It was noted, in general, that these areas are suitable for urban occupation, since they show flat geomorphology characteristics, with flattened, medium to large hills, slightly undulated, with low slope, and soils that do not present risks to the deployment of buildings, once properly managed. It was also observed a few water bodies crossing these areas and a few areas with native vegetation beyond permanent protection areas along the rivers. By the analysis of these areas and their surroundings, it was possible to determine on which area the urbanization process can occur more quickly. Thus, the study allows the City of Jaguariúna to perform a more effective occupation planning in these areas, always aiming the sustainable development and, consequently, the improvement in population’s quality of life, as well as the maintenance of environmental quality.

One of the greatest challenges for the agricultural system is to establish agricultural production combined with the conservation of genetic resources, mainly aiming to protect the Permanent Preservation Areas. In this context, mulungu ( Erythrina velutina Willd), among other native species, has been suffering with anthropogenic pressures in various ecosystems, causing reductions in its genetic basis. This work aims to identify ecological and genetic population parameters as indicators of sustainability in two natural populations of mulungu, located in riparian forest, in the state of Sergipe, and to assess the tendency to their sustainability, aiming genetic conservation of the species. The matrix of Pressure-State-Impact/Effect-Response (PEI/ER) was used with the selection of 13 indicators, from the use of RAPDmolecular markers and biochemical (enzymes) markers in populations, in order to present them as relevant information to measure progress as for sustainability and conservation ofmulungu. The studied populations presented low tendency to sustainability, requiring strategies to change this status.

The Jararaca River Basin suffers significative environmental impacts caused by inaccurate land use. In Brazil, the areas for permanent preservation are defined and protected by the 2012 Federal Law 12.651. These areas are located in the bank side and other specific places. The objective of this paper was to analyze the results of possible alternatives in function of different procedures used in the proposal elaboration. The methodology used was the elaboration of a priority map for the recovery of these areas using the Geographic Information System with multicriterial analyses and comparing it with the guidelines from the Jararaca River Basin Management Plan. As a result, there were identified differences in the priorities defined by technical issues from the priorities defined by public consultation process.

This study aimed to map the classes of use and occupation and their conflicts in Areas of Permanent Preservation (APPs) in the basin of Ribeirão São Pedro - Botucatu (SP) with the use of remote sensing techniques - image obtained by satellite 2011 - and the use of GIS. For this, we used the GIS techniques, and the integration of information held in the Geographic Information System (GIS) - IDRISI, coupled with the use of digital maps, published by the Brazilian Institute of Geography and Statistics - IBGE, scale 1: 50,000 and satellite images LANDSAT - 5 (2011) sensor TM (Thematic Mapper) with spatial resolution of 30 x 30 meters, provided by the National Institute for Space Research (INPE) .The Geographic Information System (GIS) was used IDRISI Selva and software, CartaLinx. This work had as legal support environmental legislation, specifically, the Federal Law 12.651 / 12. Thus, the study of the watershed becomes an important tool to understand its dynamics in relation to the use and occupation of their area and to characterize their environmental problems and taking as legal counsel to the preservation and conservation of the land to support environmental legislation.
