SUMMARYAraucaria angustifolia (Bert.) O. Kuntze is the main component of the Mixed Ombrophilous forest and, in the State of São Paulo, it is associated with a high diversity of soil organisms, essential for the maintenance of soil quality, making the conservation of this ecosystem a major and pressing challenge. The objective of this study was to identify the physical and chemical properties that are most closely correlated with dehydrogenase enzyme activity, basal respiration and microbial biomass under native (NF) and replanted (RF) Araucaria angustifolia forests in three regions of the state of São Paulo, in winter and summer. The main differentiating factors between the areas were also determined. Each forest was represented by three true replications; at each site, from around the araucaria trees, 15 soil samples (0-20 cm) were collected to evaluate the soil physical, chemical and microbiological properties. At the same points, forest litter was sampled to assess mass and chemical properties. The following microbiological properties were evaluated: microbial biomass carbon (MBC), basal respiration (CO 2 -C), metabolic quotient (qCO 2 ), dehydrogenase enzyme activity (DHA) as well as the physical properties (moisture, bulk density, macroporosity and total porosity), soil chemical properties [pH, organic carbon (org-C), P, Ca, K, Mg, Al, H+Al], litter dry mass, and C, N and S contents. The data were subjected to analysis of variance (Two-way ANOVA). A Canonical Discriminant Analysis (CDA) and a Canonical Correlation Analysis (CCA) were also performed. In the soil under NF, the values of K, P, soil macroporosity, and litter dry mass were higher and qCO 2 and DHA lower, regardless of the sampling period, and DHA was lower in winter. In the RF areas, the levels of moisture, porosity and qCO 2 were higher in both sampling periods, and DHA was higher in winter. The MBC was only higher under NF in the summer, while the litter contents of C, N and S were greater in winter. In winter, CCA showed a high correlation of DHA with CO 2 -C, pH and H+Al, while in the summer org-C, moisture, Mg, pH and litter C were more associated with DHA and CO 2 -C. The CDA indicated H+Al, available P, total porosity, litter S content, and soil moisture as the most discriminating variables between NF and RF, but moisture was the most relevant, in both seasons and CO 2 -C only in winter. The combined analysis of CCA and CDA showed that the contribution of the microbiological variables to a differentiation of the areas was small at both samplings, which may indicate that the period after reforestation was long enough to allow an almost complete recovery of the microbial activity.Index terms: multivariate analysis, soil quality, soil chemical properties, microbiological properties.

“…Conforme Souza (2004), ainda na década de 1950, surgia pela primeira vez a expressão desenvolvimento de comunidade, que teria sido usada pelo governo britânico em 1942, como uma preocupação para manutenção das relações com suas colônias. A partir de um contexto colonialista, portanto, o sentido do DC vai sendo construído e revelado como um processo de intervenção dirigido às comunidades -no sentido de populações locais ou rurais -com o objetivo de melhorar o nível econômico de vida.…”

“…Souza (2004) vai mais além e afirma que o propósito do desenvolvimento de comunidade é legitimar a política externa para a manutenção do crescimento econômico e o progresso dos países desenvolvidos, convergindo a ação do desenvolvimento comunitário a uma política global colonialista. Apesar disso, a ONU em 1956 define o desenvolvimento comunitário como um movimento voltado à melhoria de vida das comunidades e com participação ativa, seja através da iniciativa das comunidades ou por meio do uso de técnicas voltadas à animação do movimento.…”

“…Diante do cenário devastador começaram a surgir reações ainda na década de 1960, pois além da política de desenvolvimento comunitário corromper os princípios da participação, por meio de estratégias de manipulação para dominação, estudos sociais apontavam o crescimento contínuo da pobreza nos países "subdesenvolvidos" (SOUZA, 2004), ou seja, a política de desenvolvimento econômico não estava atendendo às necessidades sociais das ditas comunidades. Dessa situação surgiram os primeiros escritos acerca do desenvolvimento social.…”

Planejamento do turismo de base comunitária: perspectivas críticas

O presente artigo apresenta reflexões críticas acerca do planejamento do turismo de base comunitária, a partir do debate teórico dos conceitos, aplicações e sentidos do planejamento no Brasil. Para tanto, parte de algumas questões norteadoras, a saber: Quais os sentidos da participação social? Quais conhecimentossaberes se espera construir com o planejamento do turismo com as (e pelas) comunidades? Qual o papel do bacharel em turismo no planejamento do turismo de base comunitária? Acredita-se que a acepção do planejamento do turismo de base comunitária no Brasil necessita ser debatida à luz da teoria da participação social, do desenvolvimento comunitário, assim como do planejamento participativo. Essas perspectivas permitem maior clareza e leitura crítica dos processos de intervenção nos territórios ditos comunitários, o que suscita a reflexão dos limites e potencialidades da conotação da participação social. O que se pode pensar é que a política pública de turismo não legitima os sentidos genuínos da participação social. O debate teórico encaminha argumentos sobre os riscos da reprodução da lógica convencional em contextos comunitários e que incentive a autonomia nas chamadas comunidades.

Geographical patterns of terrestrial herbs: a new component in planning the conservation of the Brazilian Atlantic Forest

et al. 2015

The Brazilian Atlantic Forest (sensu lato) is constituted by Dense Ombrophilous Forest, Mixed Ombrophilous Forest and Seasonal Semideciduous Forest, in which tree species are distributed in gradients, whichever latitude, longitude, or altitude is considered. We investigated whether herb species living on the floor of these forests would have the same geographic distribution pattern. If tree and herb-layer species have coincident distribution patterns, the same conservation units can conserve both species sets; otherwise, specific conservation actions should be taken. We built a presence/absence matrix of 803 terrestrial native species in 80 surveys across the southern and southeastern Brazilian Atlantic Forest. We performed UPGMA, CA and RDA multivariate analyses in order to investigate the distribution patterns. The high degree of agreement among the analyses led us to assume that the geographic distribution of the herb-layer flora occurs as gradients among three main floristic groups: Tropical Ombrophilous forests (mostly lowland forests), Communicated by Jefferson Prado, Pedro V. Eisenlohr and Ary T. de Oliveira-Filho.Electronic supplementary material The online version of this article (Subtropical Ombrophilous forests (mostly montane and upper-montane forests in lower latitudes and sub-montane and lowland forests in higher latitudes, i.e., where temperature is lower), and Seasonal Semideciduous forests (with a marked dry season). Based on different patterns and processes between herbs and trees, and in order to encompass the highest flora diversity, we highlight the importance of creating more reserves in each one of the three main floristic groups of herb-layer species in the Brazilian Atlantic Forest.
