No leque aluvial do Rio Taquari, no Pantanal Mato-Grossense,registram-se processos de dinâmica fluvial, os quais ocasionamo fenômeno de avulsão, com a mudança de direção doRio Taquari, que altera o mosaico de paisagens e comprometea vida dos moradores residentes em colônias, a navegaçãoe as atividades econômicas. Os dados são provenientes deinformações extraídas de imagens de satélites e de trabalhode campo, e os resultados indicam que a avulsão é um processonatural, porém intensificado nos últimos anos por açõesantrópicas. Tem como exemplo socioambiental uma colôniade moradores, e as recomendações objetivam auxiliar osprogramas de planejamento para a área do baixo curso do RioTaquari, a qual apresenta riscos de novas mudanças do rio.

O cururu e o siriri são folguedos populares existentes no Pantanal brasileiro, a maior planície alagável do planeta. Esses complexos musicais e coreográficos são repletos de simbologias para os seus praticantes tradicionais. Os cururueiros portam um conjunto saberes e práticas que eram transmitidos oralmente e entre familiares e amigos, sobretudo em ambientes rurais. Esse conjunto, intitulado “Modo de Fazer Viola-de-Cocho”, foi registrado pelo Instituto do Patrimônio Histórico e Artístico Nacional (IPHAN) como Patrimônio Cultural. Apesar disso, ele corre o risco de desaparecer nos municípios de Corumbá e Ladário em Mato Grosso do Sul. Essa é uma das abordagens deste artigo que apresenta as percepções dos cururueiros frente a tal problema, além de analisar os perfis desses indivíduos e o que foi alterado em suas vidas com o reconhecimento nacional dado aos saberes que possuem.

O Pantanal, planicie inundavel composta por um mosaico de ecossistemas, vem sofrendo alteracoes na paisagem que ameacam a manutencao da biodiversidade. Neste sentido, estudos baseados no geoprocessamento de dados configuram elemento importante na compreensao do territorio, podendo contribuir para medidas de mitigacao de impactos. Este trabalho avalia a evolucao espaco-temporal da cobertura vegetal e uso da terra no Pantanal do Abobral, Mato Grosso do Sul, nos anos de 1995, 2005 e 2015. Utilizou-se o metodo do Indice de Vegetacao por Diferenca Normalizada (NDVI), aplicado a imagens de satelite Landsat 5-TM e Landsat 8-OLI. Realizou-se a interpretacao das imagens e reconhecimento a campo para identificacao das unidades da paisagem, que foram associadas a classes tematicas, conforme sua resposta espectral. Os resultados demonstraram variacoes nos valores de biomassa verde das classes entre o periodo estudado. Houve aumento da classe formacoes pioneiras em 10,5% e reducao da classe vege...

The various studies have been conducted on the use of waste materials in road construction technologies but not much efforts have been put and extensive studies have not yet been made by using variety of plastic waste through wet technology i.e. direct incorporation of waste products in bitumen as additives to improve its physical properties thereby increasing the serviceability of roads. As conventional binders have not been able to meet the requirements of special locations such as expressways, bus stops, intersections, etc. where high performance bituminous mixes are needed, use of variety of virgin polymers and plastics is well proven. The present study has been undertaken by keeping five important goals in mind these are (i) Environmental protection (ii) sustainable waste minimization (iii) improved durability of roads (iv)Resources/Energy conservation (v) Economy of road. The present study deals with the development of modified binder formulations from plastomer and elastomeric type of waste with an aim to minimize the non-biodegradable the post consumer polymer waste as well as environmental hazard, to meet this objective different samples have been picked up from several kinds of waste so as cover different categories of polymeric waste from the domestic, industrial as well as medical waste. Well we are very concerned with the present scenario of the world that civilization are being dominated by wastes, thus waste plastic, glasses etc. is everywhere from a single plastic bag at a shop to a manufacturing automobiles company ,electronic, communication etc. Waste plastic is a danger to environment that lead it to be in unbalanced state and unbalanced state of environment may the humans unbalanced later .the toxic emission, improper disposal releasing dangerous chemicals. Two types of plastic were taken thermoplastics and thermoset having their relationship with the heat i.e. change of state. These two types of plastic were seen to be satisfactory in improving the properties of flexible pavements. Frankly speaking concerned with the procedure of road laying this evil plastic cannot be fully eradicated but we can channelize the waste plastic in improving the bitumen roads and in spite of plastic low polymer wax, waste glasses is also an alternatives for an increment in strength of the road properties, this is not possible to degrade all the waste plastic. Plastic taking its position in environment in order to destroy it. This serious problem can be used in road construction as we are concerned with the road laying technically laying of flexible pavements from mixing the aggregates are being heated to particular temperature of about 1600C and the shredded plastic is mixed with the aggregates transferred to bitumen mixing chamber of temperature 170oC and the test like Softening Point, Penetration, Ductility were seen satisfactory. This utilization of wastes is eco-friendly and we can reduce the cost of bitumen being a petroleum product is costly. The internal characteristic properties while tested were increments throughout the wax, plastic & glasses when used in percentage also showed a desirable variation in the bitumen where all the results were seen at macroscopic level.
