Stepping on invisible land: on the importance of communicating the value of soils.
Soils play fundamental roles in the functioning of the Earth's ecosystems. Despite numerous initiatives to protect soils, it continues to be generally perceived as dirt or, at best, the surface we walk on. To better understand soil perception by the public, we conducted a survey with 99 participants from Poland and Brazil. We applied opportunity sampling and conducted semi-structured interviews with 40 respondents from Poland and 30 from Brazil, and 29 unstructured interviews in Brazil. Most of the respondents (53%) of the semi-structured interviews associated soil with the surface where plants grow, while 27% said that it is the ground we step on. When asked about pro-environmental campaigns, none of the respondents pointed to soil-related initiatives. Most of the respondents (99%) claimed that there is a need to increase their knowledge about the importance of soils, mostly through education (30%). The majority of the respondents of the unstructured interviews in Brazil indicated provision services provided by soils and pointed to the need for youth engagement in soil communication, corroborating the results from the semi-structured interviews. To address this, we present the results on artistic workshops as an experimental model for teaching and dissemination. We present two short documentary movies reporting the results from unstructured interviews and artistic workshops that can be used as data gathering tools, teaching tools and for dissemination purposes. This is a novel approach to communicating with the relevant stakeholders to promote more sustainable resource management

Use of Rain Forest timber in historical buildings in Rio de Janeiro
Coordenação de Aperfeiçoamento de Pessoal de NĂvel SuperiorCom a chegada dos europeus ao Brasil, inicia-se a intensa exploração dos recursos da
Mata Atlântica, direcionados primeiramente para uso da coroa e, posteriormente, para os
assentamentos populacionais da colônia. As informações sobre o uso de madeiras na época
do Brasil-colĂ´nia de Portugal (1630-1822) sĂŁo escassas e se encontram dispersas. Dessa
forma, o objetivo deste trabalho foi realizar uma referĂŞncia cruzada utilizando trĂŞs diferentes
tipos de culturas materiais: documentos histĂłricos, artefatos e paisagem. Tendo como foco as
senzalas da Fazenda Ponte Alta no estado do Rio de Janeiro/RJ, relacionou-se os dados
histĂłricos sobre o uso de madeiras de construção no perĂodo colonial com o conhecimento
cientĂfico atual sobre a flora de Mata Atlântica, identificando as espĂ©cies utilizadas no
passado e sua ocorrĂŞncia nos fragmentos florestais remanescentes. Para tal, foram visitadas
bibliotecas nacionais e internacionais; analisadas amostras das madeiras da estrutura das
senzalas e realizado um inventário fitossociológico nos fragmentos florestais remanescentes.
Como um dos principais resultados, destaca-se o expressivo número de espécies madeireiras
da Mata Atlântica que eram utilizadas nas construções do Brasil-colônia. E que a preferência
de uso de determinados táxons pertencentes à Leguminosae, Sapotaceae e Lauraceae, reflete
a disponibilidade e abundância dessas famĂlias no Bioma. Das espĂ©cies identificadas nas
estruturas das senzalas, 68% foram citadas nos documentos histĂłricos como sendo utilizadas
em construções no perĂodo colonial e 37% dessas, tambĂ©m foram amostradas no inventário
fitossociológico realizado. Constatou-se que as espécies utilizadas para construção no Brasilcolônia
apresentavam, na maioria, boa qualidade e alta resistĂŞncia o que lhes conferia uma
multiplicidade de uso. Essa demanda, certamente, tem reflexos diretos na distribuição
geográfica, no tamanho populacional e no status de conservação atual das espécies. Os
resultados indicam, tambĂ©m, que os construtores do perĂodo, principais atores da histĂłria,
detinham o conhecimento necessário à utilização das florestas locais. Assim, os dados
obtidos nos diferentes materiais analisados se mostraram complementares e com interação
entre si, agregando informação e veracidade aos argumentos inicialmente postuladosThe arrival of the Europeans to Brazil marks the intense exploitation of the Atlantic
Rain Forest resources, targeted primarily for use by the Crown, and later to the settlements of
the colony. Information on the use of wood in the Brazilian colonial period (1630-1822) is
scarce and dispersed. Thus, this study aims to do a cross-reference using three different types
of material cultures: historical documents, artifacts and landscape. Having as focus point the
slave houses at Ponte Altas Farm at Rio de Janeiro/RJ state, I related the historical data on
the use of construction timber in the colonial period with the current scientific knowledge of
the Atlantic Rain Forest flora data, identifying the species used in the past and its occurrence
in the remaining forest fragments. To this end, I visited national and international libraries;
analyzed wood samples from the slave houses and conducted a phytosociological survey in
the remaining forest fragments. One of the main results is the significant number of timber
species of the Atlantic Rain Forest that were used in the constructions of colonial Brazil. And
the preference of use of certain taxa belonging to the Leguminosae, Sapotaceae and
Lauraceae, reflects the availability and abundance of these families in the Biome. Of the
species identified in the slave houses, 68 % were mentioned in historical documents as being
used in buildings in the colonial period, and 37 % of these were also found in the
phytosociological survey. It was recognized that the species used for construction in the
colonial Brazil had mostly good quality and high resistance which gives them a multitude of
uses. This demand, surely, has direct impacts on the geographical distribution, population size
and current status of species conservation. Thus, the data obtained with the different materials
analyzed were complementary and interact with each other, adding veracity to the information
and arguments originally postulate
