Pesticidas: uma revisão dos aspectos que envolvem esses compostos

Pesticids are chemical products used to control plagues (animal and vegetable) and plant diseases. Due to the process of automation occurred in the agriculture in 1960-1970, the agrotoxics began to be largely used in Brazil. Their physical-chemical proprieties, as well as the frequency of use, form of application, environmental biotic and abiotic characteristics and climatic conditions will determine their environmental destination. These variables will define the spectrum of environmental impacts and human health problems caused by the agrotoxics. The human health impacts might be acute or chronic, mainly upon neurological, reproductive and respiratory process. In the environment, the agrotoxics cause transformations and modifications in biota, water, soil and other ecosystems. To make farmworkers aware of alternatives to massive use of agrotoxics is the guarantee for an agriculture development more sustainable, without disorders in human health and in environment

A comparative study of Odonata (Insecta) in aquatic ecosystems with distinct characteristics

The objective of this study was to compare the richness and density of Odonata larvae in four distinct environments: lotic with large pollutant loads, lotic with small pollutant loads, lentic disconnected from a river and lentic connected to a river, as well as to record the physical and chemical parameters of the water in the four environments. We identified a total of 1,302 Odonata larvae in the four habitats. The environmental variables measured were: dissolved oxygen, pH, conductivity, suspended matter, air and water temperature, precipitation, depth, and the biomass of the macrophytes. The lentic habitats exhibited a greater Odonata larvae density in relation to the lotic habitats, except during April and December of 2006. The Guareí River, however, presented an elevated conductivity, possibly because of a greater quantity of pollutants it received during the period between June and September of 2006, and it showed a higher density of Odonata larvae in comparison to the Paranapanema River. The temperature and the dissolved oxygen on the water surface were, respectively, greater and smaller in the lakes in comparison to the rivers. In spite of the Odonata density being higher in the lentic ecosystems in comparison to the lotic, the richness was not altered during the period studied. Nevertheless, the genera composition was distinct, showing that some taxa show a certain preference for certain types of ecosystems like Calopterygidae and Neogomphus, which were shown exclusively in the Paranapanema River.

Contribuições para a proposta de uma política municipal de pagamento por serviços ambientais: o caso de Botucatu/SP

Environmental services are the ones done by the nature, that supports both the life and the environment. Payments for Environmental Services (PES) are financial transfers by beneficiaries of environmental services for the ones who provide such services due to conservation practices. Botucatu is a city in São Paulo State with a great potential for PES. Therefore, this paper develops a comparative study of PES projects in Federal and State ranges, aiming to analyze, select and propose criteria in order to contribute to the creation of a PES policy for the city.

Uso inadequado de áreas de preservação permanente

O grande desafio da população mundial é a conservação ambiental, pois as Áreas de Preservação Permanentes, que têm papel vital dentro de uma microbacia, por serem responsáveis pela manutenção, preservação e conservação dos ecossistemas ali existentes. O presente trabalho visou analisar os conflitos de uso do solo em áreas de preservação permanentes (APPs) da microbacia do Alto Capivara - Botucatu (SP) através do uso de Sistema de Informações Geográficas e de imagem de satélite digital. A área com 4551,19ha, situa-se entre as coordenadas geográficas: 22o 51’ 57” a 22o 57’ 55” de latitude S e 48o 21’ 58” a 48o 26’ 38” de longitude WGR. O mapa de uso do solo de 2006 foi obtido a partir da classificação supervisionada em imagem de satélite digital de 23/10/2006. Na identificação digital dos alvos foram utilizadas as chaves de interpretação para imagens e as áreas foram determinadas através do software SIG – IDRISI. Os conflitos de uso nas áreas de preservação permanente foram analisados ao longo da rede de drenagem e das nascentes, conforme itens dos artigos 2º e 3º da Resolução nº 303 do CONAMA. A área de APP discriminada ao longo da rede de drenagem foi de 416,5ha (9,15%) . No entanto, 201,15ha da área de APP está ocupada com pastagem (48,3%), reflorestamento (1,23%) e 0,48% por área urbana de forma inadequada (conflito). Portanto, quase 50% de área de APP vem sendo parcialmente utilizada adequadamente.

Avaliação das áreas de conflito de uso em APP da microbacia do alto água fria, Bofete (SP)

The misuse of land by man and is causing serious problems to the environment, resulting in ecological imbalance and depletion of natural resources, especially when it comes to areas of permanent preservation, that ecosystems are essential for balance and water conservation importance . Conflicts of land use is a major cause of silting of rivers and water bodies, causing significant losses in soil and decaying natural water resources both in quantity and in quality. Within this scenario, the planning becomes essential for the control of environmental impacts to the environment factor. This study aimed to evaluate land use conflicts in permanent preservation areas of the stream Água Fria watershed, Bofete (SP) using Geographic Information System and satellite image of LANDSAT - 5 of 2010, scale 1:50000. The results show that 51.16% of the permanent preservation areas of the watershed are conflicting, especially for pasture (88.94%) and reforestation with eucalyptus (11.06%). The GIS IDRISI Selva and Cartalinx along with GIS techniques demonstrated speed and efficiency in identifying, measuring and editing maps of land use, preservation and ongoing conflicts in areas of permanent preservation.

Potencial de Invasão de eucalipto pelas sementes produzidas nos plantios comerciais

Over the past few years, the area of planted forests has expanded considerably in Brazil, reaching a level of 6.3 million hectares, which represents approximately 0.7% of the country, mainly with some species of the Eucalyptus genus. However, due to the global concern with biological invasions by exotic species, risk assessment is necessary to evaluate the potential of Eucalyptus species escaping cultivated stands and invading surrounding native ecosystems. Seedlings by natural regeneration from Eucalyptus grandis and E. urophylla, pure and hybrids between the two species were evaluated, by assessing natural regeneration of Eucalyptus in 18 sites located in Brazilian states with plantation forest tradition (Minas Gerais, São Paulo, Rio Grande do Sul and Espírito Santo). Sample plots were installed in the planted stands, along forest roads and in a nearby pasture or native vegetation.,at different distances from the Eucalyptus stands. Regeneration of Eucalyptus was not recorded in 90% of the plots installed outside the eucalipt stands. However, seedlings of eucalypts were observed in 29% of the plots within the commercial stands (mean density of 37 seedlings per hectare) and 40% of the plots located along forest roads (157 seedlings per hectare on average), but no adult plants by natural regeneration were found. The seedlings of eucalypt species studied rarely were found beyond the limits of the cultivated areas. In the planted stands or along forest roads, eucalypts can germinate, but the seedlings apparently do not establish. So the potential for invasion by seeds produced in commercial plantations of Eucalyptus is low.
