The distribution of agricultural land and the question of agrarian reform in Brazil

Agrarian reform has long been an acute issue in Brazil, where the distribution of cultivable land is extremely unequal. The Land Statute adopted by the military in 1964 constituted a genuine reform programme, which, however, was never implemented as the government chose to modernize agriculture and expand cultivated areas. This has prevented the poorest from having access to the land.-from English summary

Preliminary selection of acerola genotypes in Brazil

Introduction. Breeding studies for acerola (Malpighia glabra) improvement aim at obtaining plants that produce fruits with uniform chemical and physical attributes, including high levels of vitamin C, which can provision the market with fresh fruit and frozen pulp. High variability in fruit quality is observed in Brazilian acerola crops, especially those propagated by seeds. In this context, the objective of our research was to evaluate the physical and chemical characteristics of Brazilian acerola genotype fruits. Materials and methods. Sixteen acerola genotypes were studied in Jaboticabal, São Paulo State, Brazil. A completely randomized design with sixteen treatments and six replications was adopted. Each treatment was represented by one genotype. Several parameters related to fruit quality, such as width, length, weight, pulp percentage, soluble solids (SS), titratable acidity (TA), [SS / TA] ratio and vitamin C content, were evaluated in fruits of the acerola genotypes. The results were submitted to variance analyses, the Tukey test and cluster analysis. Results and discussion. There was a statistical difference between the acerola genotypes studied. Three of them stood out as natural sources of vitamin C. In spite of fruit size, two acerola genotypes were found to have potential for fresh fruit production. In a general form, genotypes that presented a high [SS / TA] ratio had low vitamin C content. Conclusion. The acerola genotypes studied in Jaboticabal presented high variability, forming eleven groups in relation to fruit quality parameters. © 2007 Cirad/EDP Sciences All rights reserved.

High temperature tolerance of determinate tomatoes in Brazil

The experiment was conducted in the experimental area belonging to the Section of Crop Production and Aromatic Medicinal Plants of the FCAV-UNESP, Jaboticabal Campus - Sao Paulo, Brazil. Tolerance to high temperature was studied in six determinate genotypes of tomato (Lycopersicon esculentum L.): Agrocica 8, Apex 1000, Botu-13, Calmech VFAS, Nemadoro and Jab-2, which were cultivated in a greenhouse at temperatures above 33oC for at least 2 h/day during blooming. The objectives of the study were to identify the genetic diversity of the genotypes studied and to determine their performance associated with tolerance to high temperature. Dissimilarity was determined by the generalized Mahalanobis distance. Delineation groups were optimized with the Tocher technique. A random block design was utilized with six treatments and with three replications. Two similarity groups were identified: 1 - Apex 1000, Botu-13, Calmech VFAS, Jab-2, Nemadoro and 2 - Agrocica 8. Crossing of genotypes within one group has no advantage because little genetic divergence and no heterotic response would be expected. However, the crossing of genotypes between groups is suggested. Knowledge of these groups will be important for efficiency future breeding efforts.

High temperature tolerance of indeterminate tomatoes in Brazil

The study was conducted at the Section of Crop Production and Aromatic Medicinal Plants of FCAV-UNESP, Jaboticabal Campus - Sao Paulo, Brazil. Nine indeterminate tomato (Lycopersicon esculentum Mill.) genotypes, Jumbo, Santa Clara, Cláudia VF, Concorde, Débora Plus, FM-9, Carmen, Príncipe Gigante, and CL 5915, were evaluated for high temperature tolerance. Three determinate tomato genotypes, FM-9, Suncoast and TSW-10, were cultivated in a greenhouse at more than 33°C air temperature for at least 2 h/day during bloom. The objective was to identify variable genotypes to determine their tolerance of high temperature. Four replications of fifteen treatments were planted in a randomized block design. Dissimilarity was determined by the generalized Mahalanobis distance. Delineation groups were optimized with the Tocher technique. The tomatoes were classified into six groups of similar temperature responses. CL 5915 was the most tolerant of high temperatures. Crossing of genotypes within one group has no advantage because little genetic divergence and no heterotic response would be expected. However, the crossing of genotypes between groups is suggested. Knowledge of these groups will be important for efficient future breeding efforts.

Climatic variables and altitude as predictors of anuran species richness and number of reproductive modes in Brazil

Because anuran species are highly dependent on environmental variables, we hypothesized that anuran species richness and the number of reproductive modes from different Brazilian localities vary according to climatic and altitudinal variables. Published data were compiled from 36 Brazilian localities and climatic and altitudinal data were extracted from an available database. A partial redundancy analysis (pRDA) showed that 23.5% of the data set's variation was explained by climatic and altitudinal data, while the remaining 76.5% remained unexplained. This analysis suggests that other factors not analysed herein may also be important for predicting anuran species richness and the number of reproductive modes in Brazil. Altitude and total annual rainfall were positively correlated with anuran species richness and the number of reproductive modes, and total annual rainfall was strongly associated with these two biotic variables in the triplot of pRDA. The positive association of total annual rainfall and the negative association of the concentration of annual rainfall were already expected based on physiological and reproductive requirements of anurans. On the other hand, temperature was not associated with richness or the number of reproductive modes. Copyright © 2010 Cambridge University Press.

Conservation and use of palm trees in Brazil's landscaping

Palm trees belong to the Arecaceae family and are widely utilized in landscaping of tropical countries. Although there are many species, just a few are used in Brazil's landscaping, the majority coming from other countries. So, this study had the objective to characterize the plants in the collection of palm trees at UNESP/FCAV, Campus of Jaboticabal, Sao Paulo State, Brazil. The germination of seeds was also studied to increase the production of seedlings for use in landscaping, as this is the biggest difficulty for spreading new species. The introduction of new species in the collection was accomplished. It was also made a survey of major pests and diseases that occur in the collection. The most common pests found were: Brassolis sophorae, Parisoschoenus obesulus, Rhynchophorus palmarum and Coraliomela sp., and the most common disease causing fungi: Colletrotrichum sp., Curvularia sp., Bipolaris sp., Helminthosporium sp., Alternaria sp., Phyllosticta sp., Pestalotia sp., Exosporium palmivorum and Ceratocystis pardoxa.

Green teams: Understanding their roles in the environmental management of companies located in Brazil

Green teams are frequently considered in the state-of-the-art literature as an essential factor for companies aiming to implement and improve environmental management approaches and practices. However, most of the available literature on green teams is conceptual and theoretical by nature. Therefore, the main purpose of this article is to evaluate the main characteristics of green teams in Brazilian companies and to analyse the relationships between green teams and the maturity level of environmental management in those companies. Based on a conceptual background on corporate environmental management and green teams, a research was done in two complementary phases: a survey of 94 companies with ISO 14001 certification; and a multiple case study of four industrial companies. Survey results suggest that 82% of the studied companies have cross-functional green teams, i.e. involving various companies' departments; and 65% have functional green teams, i.e. individual department teams. The results of the case study suggest that the use of green teams is an instrument to the greening of companies with ISO 14001 in Brazil. The company with the most proactive and advanced environmental management is the same company which uses green teams more intensely. Green teams are especially necessary for implementing more technical environmental management practices, e.g. Life Cycle Assessment. Since this is one of the first studies analysing green teams, the results presented can be useful for companies and public policies aiming to implementation of environmental initiatives. © 2012 Elsevier Ltd.

A system for environmental monitoring of hydroelectric reservoirs in Brazil

Environmental monitoring of aquatic systems is an important tool to support policy makers and environmental managers' decisions. Long-term, continuous collection of environmental data is fundamental to the understanding of an aquatic system. This paper aims to present the integrated system for environmental monitoring (SIMA), a long-term temporal series system with a web-based archive for limnological and meteorological data. The following environmental parameters are measured by SIMA: chlorophyll-a (µgL-1), water surface temperature (ºC), water column temperature by a thermistor string (ºC), turbidity (NTU), pH, dissolved oxygen concentration (mg L-1), electric conductivity (µS cm-1), wind speed (ms-1) and direction (º), relative humidity (%), shortwave radiation (Wm-2) and barometric pressure (hPa). The data were collected in a preprogrammed time interval (1 hour) and were transmitted by satellite in quasi-real time for any user within 2500 km of the acquisition point. So far, 11 hydroelectric reservoirs are being monitored with the SIMA buoy. Basic statistics (mean and standard deviation) and an example of the temporal series of some parameters were displayed at a database with web access. However, sensor and satellite problems occurred due to the high data acquisition frequency. Sensors problems occurred due to the environmental characteristics of each aquatic system. Water quality sensors rapidly degrade in acidic waters, rendering the collected data invalid. Data is also rendered invalid when sensors become infested with periphyton. Problems occur with the satellites' reception of system data when satellites pass over the buoy antenna. However, the data transfer at some inland locations was not completed due to the satellite constellation position. Nevertheless, the integrated system of water quality and meteorological parameters is an important tool in understanding the aquatic system dynamic. It can also be used to create hydrodynamics models of the aquatic system to allow for the study of meteorological implications to the water body.
