“…Ao avaliar a qualidade da água com diferentes usos do solo nas áreas de nascentes da bacia hidrográfica do rio Mogi Guaçu, Pinto et al (2012) mostraram que as nascentes protegidas por mata ciliar apresentaram qualidade da água superior à daquelas que possuíam o uso de cultura agrícola.…”

PALAVRAS-CHAVERapidEye Geoprocessamento Uso da terra SIG KEYWORDS RapidEye Geoprocessing Land use GIS RESUMO: As ações antrópicas sobre os recursos naturais no Brasil revelam que não está havendo cumprimento da legislação, principalmente no que se refere às áreas de preservação permanentes (APPs). O objetivo deste trabalho foi delimitar as APPs e mapear as classes de uso e cobertura da terra presentes na bacia do rio Piauitinga, no estado de Sergipe, averiguando se há conflitos de uso nas áreas de preservação. A demarcação das classes de uso e cobertura da terra ocorreu de forma manual, mediante a interpretação visual de imagens RapidEye. No mapeamento das APPs, foram utilizadas técnicas de geoprocessamento sobre as informações do relevo e a rede hidrográfica. A principal classe de uso e cobertura da terra mapeada foi a de pastagem (50,39%). Das três classes de APPs identificadas, ao longo dos cursos d'água (3,85%), lagos superficiais (0,80%) e ao redor das nascentes (0,08%), todas apresentaram conflito de uso e cobertura da terra. Pode-se afirmar que não está havendo respeito aos limites de APPs na bacia, principalmente em relação às áreas ao redor das nascentes, revelando, principalmente, conflito com a classe pastagem. ABSTRACT: The human action over the natural resources in Brazil shows us that legislation has not been accomplished, mainly when the subject is Permanent Preservation Areas (PPAs). The purpose of this work was to delimit the PPAs and to map the classes of land use and land cover present in the Piauitinga river basin, verifying the existence of land use conflicts in the PPAs. The demarcation of land use and land cover classes occurred manually, through the visual interpretation of images RaddiEye from the 2013 year. The delimitation of the PPAs proceeded based on the elevation digital model and hydrographic network information. The main land use and land cover classes mapped were farming culture (18.44%), native vegetation (22.69%) and pasture (53.11%). From the three PPAs classes identified

“…Estes resultados contrapõem aos estudos feitos por Pinto (2012) no qual outros parâmetros como "velocidade de subida a superfície" e "mobilidade" foram afetados, e apresentaram ser efeitos dose dependentes. Isto aponta para a possibilidade de que a demanda então produzida não apresenta riscos ambientais nítidos.…”

“…purpurea exposta à água dos arroios Portão (Portão) e Pampa (Novo Hamburgo), respectivamente. As nascentes configuram locais onde aflora naturalmente a água subterrânea, desempenhando um papel fundamental para a manutenção da qualidade e quantidade da água dos arroios e rios (Pinto et al, 2012). Quando localizadas em áreas urbanas, as nascentes tornam-se descaracterizadas e vulneráveis à degradação pela redução da vegetação arbórea em seu entorno, bem como pela alta densidade populacional e atividades antrópicas a ela relacionadas, tais como deposição inadequada de resíduos sólidos no entorno e lançamento de esgoto doméstico.…”

1022-1022Ambiente & Água -An Interdisciplinary Journal of Applied Science ISSN 1980-993X -doi:10.4136/1980 The following list (Table 1) includes the names and affiliations of all reviewers that evaluated the submissions processed for Volume 11, 2016 of Revista Ambiente & Água, including manuscripts that were accepted and published in one of the four annual issues and also manuscripts submitted and rejected in 2016 up to October 10, 2016. It may therefore include the names of reviewers that completed their evaluations between September, 2015 and October, 2016. We are deeply indebted to all of them that voluntarily and anonymously spent their precious time to support the journal, and contributed immensely to the quality of the published articles. We gratefully acknowledge their professional work and outstanding product. Note: 1) Some of these reviewers evaluated more than one manuscript; 2) This list includes reviewers that evaluated submissions that were not accepted for publication, in addition to the ones published in 2016.As seen in Table 2, 21 reviewers are from international institutions. This is an indication that the journal is gaining international acceptance and inclusion. ABSTRACTThis paper discusses the reverse logistics of empty agrochemical containers, the partners involved, and it focuses on the participation of the Agricultural Defense Agency of the São Paulo state government in reducing the risk of water and soil contamination in order to preserve these resources for future generations. O sistema de logística reversa e o papel da fiscalização governamental para a preservação do solo e da água: o caso das embalagens vazias de defensivos agrícolas RESUMO Este trabalho tem por objetivo demonstrar como a logística reversa das embalagens vazias de agrotóxicos funciona, quais são os parceiros envolvidos, focando na participação da Defesa Agropecuária do governo do Estado de São Paulo, na redução dos riscos de contaminação de água e solo, com o objetivo de preservar estes recursos para as gerações futuras.Palavras-chave: agricultura, agrotóxico, contaminação ambiental. DISCUSSIONConsidered a regulatory landmark in 1989, a Brazilian federal law first demonstrated the country's concern with the handling and disposal of pesticide containers. Previously, most of the focus was on pesticide efficiency and most of the containers were made of glass, not of plastic as they are today. The environment was still not considered an important concern, and even today Brazil is the largest consumer of pesticides worldwide. The correct handling and disposal of pesticide containers is therefore of primary importance in public policy. Brazil's Federal Laws 7802 (Brazil, 1989), 9974 (Brazil, 2000 and Decree 4074 (Brazil, 2002) regulate the obligation to return empty pesticide containers to retailers or producers. In 2010, reverse logistics was defined by Federal Law 12305 (Brazil, 2010), which created the National Policy on Solid Waste. According to this law, reverse logistics can be understood as a set of actions...

This study aimed to define potential areas for forest conservation to improve water quality, using Multicriteria Evaluation (MCE); and to verify differences between results from a multidisciplinary group of experts. We worked with the Pirapora River Watershed, Piedade/SP. The participatory method was used to identify the criteria and their relative importance. Priority maps representing expert opinion were elaborated, as well as a map with average weight values. We compared the differences between the criteria weight values and the maps of priority areas. The maps proposed distinct spatialization of priority areas, supporting the understanding of criteria that influence the decision-making process. The highest priority level was associated with areas near to springs, forest patches, and with the highest slope values. We concluded that the MCE is an efficient method to identify priority areas; however, the selection of an expert group is an essential step to generate representative analyses.
