The current concern with environmental issues by the scientific community, governmental and civil society also brings out the need to recover, preserve and conserve the environment. With this understanding, this work was prepared, which had as one of the main objectives of the historical process of land use and occupancy of the Pontal, since the nineteenth century to the present day. From this, the changes were evident in the types of land use, which rose from native forest to plant crops (permanent and temporary crops) and later as pasture. Through this process of occupation, exploitation of forests and replacement even three, Reserves being brought from the Far West Paulista, through the state government of Sao Paulo, they were almost decimated. Such areas decreed by law to be preserved and conserved, with the rampant occupations, were suffocated by the fakes and illegal occupation of land tenure contracts, leaving the region currently only a few forest fragments and protected areas of State Park Morro do Diabo, PRNP Boa Vista and Ecological Station Black Lion Tamarin. Furthermore, the article emphasizes the main legislation being developed by federal and state levels aimed at protecting natural resources and the effectiveness they had with the passage of time, demonstrating that the conservation of the environment, has several contributions in the law, however, and they are so vast that hinder its application.

A vida nas grandes cidades distancia cada vez mais o ser humano e a natureza, e a necessidade de parques e áreas verdes dentro das grandes zonas urbanas nunca foi tão evidente. Nesse cenário, o papel dos jardins botânicos deixa de ser meramente científico, para assumir também um lado mais voltado à educação ambiental. Vários exemplos espalhados pelo mundo, inclusive no Brasil, confirmam esta afirmação. A proposta de um Jardim Botânico para Paranapiacaba, famosa pela frequente neblina, se deve ao fato de ser ela uma vila histórica, cravada no que ainda resta da Mata Atlântica, em São Paulo. Seu conjunto arquitetônico de edificações em estilo inglês – no qual se destacam a reconstituição da estação ferroviária, utilizada atualmente para o turismo ferroviário, bem como seu original relógio londrino – e o entroncamento ferroviário são dos mais significativos exemplos da arquitetura e da engenharia ferroviária inglesa dos fins do século XIX. Por isso, Imagem 1 – O relógio Johnnie Walker Benson foi construído em Londres no século 19 e é o símbolo da Vila de Paranapiacaba Foto: Henrique Granado, disponível em: http://www.panoramio.com/photo/24325448 Jardim Botânico em Paranapiacaba 7 em 1987, a vila foi tombada pelo Patrimônio Estadual (CONDEPHAAT); em 2000, pelo World Monument Fund, como Tesouro Cultural Mundial; em 2002, pelo Instituto do Patrimônio Histórico e Artístico Nacional – IPHAN e, em 2003, pelo Patrimônio Municipal (COMDEPHAAPASA). Apesar de o local carecer de investimentos em uma série de segmentos, é viável um projeto que alie a preservação da mata nativa com o turismo ecológico crescente na região. Assim, um Jardim Botânico em Paranapiacaba é um projeto viável e o objetivo deste trabalho

The massive urbanization and activities arising from the uncontrolled growth of urban areas, result in changes on the climate, making it unhealthy. One factor that contributes to poor quality of life due to this fact is the islands of heat that consists in the accumulation of surface heat and raises the temperature in the cities. The vegetation consists of urban greening, urban forests and green areas, have the function to minimize this effect. To reconcile these factors, collected data on surface temperature by satellite images, LANDSAT 5 captured on 18/12/2012 point 75 e 76, orbits 221, band 6 and on-site survey with thermo-hygrometer, possessed the data, crossing the conducted vegetative survey and provided a management vision to improve the microclimate of the city under study. The vegetation coverage at urban area directly affects the ambient temperature, improving the urban micro-climate. The different analyzed surface coverage also affects the apparent temperature. Among the studied ranks, the eucalyptus cultivation, native forest, urban area and solo exposed areas with greater vegetation cover have mild temperatures and improved microclimate.

Evaluation and adequacy of land occupation in Permanent Preservation Areas (PPAs) are important to ensure quantity and quality of water and local biodiversity. The objective of the study was mapping PPAs according to the Brazilian Forest Code and quantifying land cover and use, establishing the conflict of PPAs occupation in the Ribeirão Lavapés sub watershed. The area is 11,154.58 ha, and is located in Botucatu city, Midwestern region of São Paulo state. For this reason, geoprocessing tools, such as Remote Sensing and the Geographic Information System (SIG) were used. The dominant classes of land use and cover were the Urban Zone in Reverse Cuesta, 4,394.27 ha (39.39%) and Annual Crops in the Peripheral Depression, 3,670.89 ha (39.39%). The mapped area of native forest vegetal cover in the sub watershed was of 1,109.70 ha. Regarding the mapping of PPAs, considering the total area of 1,721.80 ha, a total of 532.15 ha (30.91%) are covered by Riparian Forest and 1,189.65 ha (69.09%) had no native riparian vegetation, therefore, requiring its reforestation.

The final disposal of municipal solid waste in unsuitable areas without an infrastructure that meets the health measures and environmental protection, coupled with the lack of technical criteria in phase and decommissioning of the dump can promote environmental degradation. Alternatively to minimize the impacts of this activity for the stabilization of the area by isolating the massive waste with implementation of an adequate and finished by a layer of soil for plant growth final cover system. In this context, the present study aimed to evaluate the quality of the final cover in the area of a disabled dump the tropical semi-arid region in order to assist the process of recovery of these areas. The study area is located in the tropical semi-arid region in São João do Sabugi /RN. Soil samples were collected in the dump area and bushland as a benchmark of quality. To which they were subjected to analysis of physical attributes (particle density, bulk density, grain size and porosity), chemical properties (pH, K + , Na+ , Ca2 + , Mg2 + and Al3 + exchangeable, potential acidity, available phosphorus, sum of bases, CEC, base saturation, aluminum saturation, saturation Na + and adsorption ratio sodium, total organic carbon and total nitrogen) and total and soluble concentrations of heavy metals (Mn, Pb, Zn, Cd, Cu, Mo, Co, Cr, Ba and Ni). The differences between physical and chemical soil under native forest and final cover showing reduction of soil quality in the area off to the dump, which hinders the development of native vegetation and the recovery of the area. The absence of superior waterproofing to allow vertical transfer between the solid waste and the final cover promoted enrichment by chemical elements and heavy metals in excess can impair revegetation. Deficiencies found in the construction process of the final cover point to the need for intervention to accelerate the process of stabilization and recovery of the area of the local ecosystem
