SPATIAL VARIABILITY OF HYDRAULIC CONDUCTIVITY OF SATURATED SOIL IN CONSERVATION UNIT
Provedor de dados: 196
Autores: Mesquita, Glaucia Machado; Santos, Felipe Corrêa Veloso dos; Dores, Anne Louise; Correchel, Vladia.
The study aimed to evaluate the hydraulic conductivity using soil samples with undisturbed structure in the soil layers of 0-5, 5-10, 10-20, and 20-40 cm; 120 soil samples were collected. For the determination of hydraulic conductivity, the constant load permeameter was used. For geostatistical analysis, exploratory data analysis was performed using frequency histograms, determining the main measures of position and dispersion, verifying the trends for the construction of boxplot graphics, which allows the identification of discrepant points. The lowest and highest hydraulic conductivity values were found in the 20-40 cm and 0-5 cm soil layers, respectively; values commonly found in soils under forest conditions. Based on the results, we conclude when the...

Preliminary indicators for restoration assessment in riparian reforestations
Provedor de dados: PFB - Pesquisa Florestal Brasileira
Autores: Reis, Daniele Nogueira dos; Davide, Antonio Claudio; Furtado Ferreira, Daniel.
The restoration success in forest ecosystems can be adequately assessed by correct selection of indicators that represent the achievement of established goals. The discriminant analysis technique on indicators selection consists of separation and classification of new observations on pre-defined groups, reducing the number of variables that are discriminant functions linearly dependent of the original variables. This study aims to define an index composed by structural attributes (number of species and individuals planted, height, basal area, number of regenerant species and individuals) and chemical and pedological soil attributes to classify riparian reforested environments regarding to restoration taking as reference reforestation around the the Volta...

AVALIAÇÃO DO PROCESSO DE IMPLANTAÇÃO DE PROJETOS DEMONSTRATIVOS PARA A RECUPERAÇÃO DE MATAS CILIARES NO ESTADO DE SÃO PAULO
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chabaribery,   Denyse; Monteiro,   Ana Victoria; Silva,   Jose Roberto; Ramos,   Soraia Fatima.
O artigo faz a avaliação da fase inicial de implantação de projetos demonstrativos para recuperação com espécies nativas de áreas degradadas em mata ciliar em três microbacias no Estado de São Paulo. O arcabouço teórico considerou o projeto como um modelo de conservação da biodiversidade, entendendo que deveria ter havido um enfoque transdisciplinar das instituições parceiras. A pesquisa utilizou-se das técnicas de delphi para levantar os depoimentos dos envolvidos no acompanhamento e na execução das áreas experimentais. Em parte a transdisciplinaridade foi conseguida e houve sucesso no plantio das áreas pilotos em três microbacias estudadas. Mas, a avaliação geral foi de que as equipes locais não tiveram o apoio necessário dos componentes de educação...

An evaluation of the economic viability of environmental offsets in the saltworks industry
Provedor de dados: Ciência Rural
Autores: Fernandes,Rogério Taygra Vasconcelos; Pinto,Aruza Rayana Morais; Fernandes,Raimunda Thyciana Vasconcelos; Oliveira,Jônnata Fernandes de; Novaes,José Luís Costa.
ABSTRACT: The extraction of sea salt depends on the occupation of large areas at the estuary banks, many of them inserted in Permanent Preservation Areas (PPAs). Thus, the objective was to evaluate the economic viability of Environmental Offsets (EO) as an alternative to the unoccupied PPAs in the saltworks. In order to do so, 27 solar saltworks installed in the region of the Brazilian White Coast were evaluated for the occupation of PPAs - measured using images from satellite, georeferenced, vectored with corresponding PPA bands generated - and estimated to EO (Impact Degree x Sum of the investments necessary to implement the project) and Economic Impact (Net Present Value, with long-term interest rate of 7%) of vacating PPAs. It was considered that EO...

Atlantic Forest scenarios under the parameters of forestry laws
Provedor de dados: Ciência e Agrotecnologia
Autores: Silva,Liliane Garcia da; Mendonça,Bruno Araujo Furtado de; Silva,Eliane Maria Ribeiro da; Francelino,Márcio Rocha.
ABSTRACT Remote sensing allows for identification of regularities and irregularities in land use and land coverage (LULC) change in relation to environmental legislation. The aim of this study was to delimit scenarios in the permanent preservation areas (PPAs) according to the Brazilian forestry law, with or without consolidated uses in the basin of Capivari River and the State of Rio de Janeiro in the Atlantic Forest biome. Mapping and analysis were performed on LULC in areas of permanent preservation using the following data: RapidEye-REIS satellite scenes acquired in 2012 and Bhattacharyya distance classifier and hydrography of the basin and digital elevation model (1:25.000) using Spring and ArcGIS software. The legal scenarios adopted were as follows:...
