Conhecimento popular sobre plantas medicinais em comunidades rurais de mata atlântica - Itacaré, BA, Brasil

This study's goal was to caryy out an ethnobotanical survey focusing on the knowledge and use of medicinal plants within two rural communities (Marambaia and Camboinha), which are situated in an Environmental Protection Area in Atlantic Forest of Southern Bahia, Brazil. These communities use medicinal plants as an important therapeutic activity, which permits the rural inhabitants to be self-sufficient regarding health care. Data were collected through interviews with 26 families (24% of the total). The medicinal plants collected (98 species) were catalogued, identified and deposited at the Herbarium Rio Clarense (HRCB). They belong to 40 families so that Lamiaceae was the most cited. The majority of these species (78%) are cultivated, usually in backyards by local inhabitants. The leaf is the most common part of the plant used in medicinal preparations. The species with the greatest number of citations were Chenopodium ambrosioides L. and Lippia alba (Mill) N.E. Br. These species are also associated with the highest number of therapeutic uses. Use agreement and diversity index from this survey were compared to other surveys conducted in Brazilian Tropical Forests.

Tipificação das famílias de oito assentamentos rurais da região de Andradina (SP), com base em diferentes estratégias de produção e comercialização

This article intends to provide a typology of the families that are settled in the region of Andradina (Sao Paulo state), according to the main production and commercialization systems and to the presence (or not) of agricultural income diversification. The empiric data used to form the groups originate from socioeconomic questionnaires that had been applied to 169 families of eight rural settlements and also from 80 interviews. The groups were compared with each other, starting from the family's profile; patrimony; credit and technical support; self-consumption production; and the lot's external income. The strategy to increase the production and the productivity (dairy cattle) is limited to less than a quarter of the producers, however different strategies had been used by families, such as the diversification of the agricultural income and the direct sale to the consumer or to the retail trade. The association of the production diversification with the use, in a regular way, of differentiated channels of commercialization demonstrated a strategy capable to approximate the indicators of this type of producer comparing with those that focused on increasing the production and the productivity. This verification is important because, even though there is no necessary contradiction among both strategies, a part of the families does not have resources, infrastructure and/or technical qualification to follow the way of the productive intensification and others do not have this project as a priority.

Controle de erosão em estradas rurais não pavimentadas, utilizando sistema de terraceamento com gradiente associado a bacias de captação

The agricultural unpaved roads are important road structures for the economic and social agricultural development of the Nation, and the erosion provoked by rain water in the road bed and sides are closely related to bad draining, one of the main factors for their degradation. In order to make the draining system adequate, it is necessary to know about erodibility, infiltration capacity of water in the ground and adoption of mechanical slope abatement with grid elevation and water interception. This study presents drainage model through the construction of terraces with gradient transversally associated to the capitation basin in abruptic red dystrophic argisol soils, medium sandy texture, based on slops abatement techniques, elevating the road bed and deviating flow. The grain sized fractions of this ground (sand, silt, clay) and the aggregate stability indicated that this ground, under anthropic action, presents erosive processes resulting in superficial draining with ground hauling, sanding sources and courses of water situation below roads, providing great environmental impacts in the hydric bodies. The reduction of erosion problems in these unpaved roads is in the adoption of measures that intercept waters from the draining of their stream bed itself, as well as pluvial waters comings from adjacent areas of contribution, that are collected and conducted to inlaid terraces and capitation basis.

O conhecimento sobre os recursos vegetais alimentares em bairros rurais no Vale do Paraíba, SP, Brasil

The objective of this study was to conduct an inventory of food plants cultivated and collected from the native and ruderal vegetation in the Atlantic Forest region by the rural population residing in the Santa Virginia Nucleus of the Serra do Mar State Park (Puruba and Guaricanga neighborhoods) and surroundings (Vargem Grande neighborhood). The 23 interviewees were sampled to meet the following criteria: originating from the rural area of the municipalities where the Nucleus is located; more than 45 years old; close familiarity with working the land. A total of 146 botanical species were identified, distributed among 43 botanical families, with the families Solanaceae and Cucurbitaceae being the most represented and basically horticultural. The Shannon-Wiener diversity index and Pielou evenness were 1.90 (base 10) and 0.95, respectively, for the group residing in the Nucleus and 1.97 and 0.92 for the population located in the area surrounding the Nucleus. The two groups of neighborhoods presented similarity regarding the food plants cited (75%), and about 17% of the plants cited are native to the Atlantic Forest. We found significant richness and variety of species cultivated in the yards and fields which serve to complement the diet, which is composed mainly of items purchased at local businesses. The rural communities studied revealed themselves to be an important germplasm conservation system for cultivated plants, with 96 ethnovarieties identified for 12 botanical species, most of which are kept in the communities.

Adoção da tecnologia da informação em organizações rurais: O caso da pecuária de corte

Adoption of technology. Farm management. Beef cattle breeding. Information technology.This research is aimed to study the use and the diffusion of IT in the beef cattle breeding from the analysis of the factors that have influenced its adoption as well as to describe resources, procedures, and necessary actions for IT operation using case studies in rural properties classified by the innovativeness degree. This study was carried out in two stages, quantitative and qualitative. In the first stage, a survey with producers was conducted. Information concerning the different technologies adopted enabled to identify the level of innovativeness of those producers. They were classified according to the similarities of the technological position. The second stage analyzed experiences, opinions, and perspectives regarding the technology integrated to the productive system. Two rural cattle breeding farms were analyzed in each category through personal interviews totalizing ten case studies. The results indicated the reasons for the adoption or rejection of a certain IT by the producers allowing for the identification of the reasons why some producers have adopted it more quickly than others. It was possible to understand the rural organization modifications due to IT adoption, for example, managerial skills improvements. In general, the processes have been improved and become easier bringing positive effects to several areas including human resources and the enterprise's image in the market.

Influência da combinação de dados GPS e GLONASS no georreferenciamento de imóveis rurais

The land question has been a widely discussed topic in Brazil, regarding land tenure. Law No. 10.267/01 was a major breakthrough for the agrarian issue. Since then on all rural properties must be georeferenced to the Brazilian Geodetic System (BGS). Therefore, satellite positioning and conventional methods are extensively used. Changes have been occurring in satellite positioning systems due to the addition of new signals in GPS (Global System Positioning), restructuring of GLONASS (Global Orbiting Navigation Satellite System), and the new systems like Galileo and Compass as well. To evaluate the effects of combining GPS and GLONASS data, several batches of processings were performed on different configurations. The data processing was performed to determine the coordinates of points of basic support and those materializing the neighborhood of the rural properties. As a result, it was found that the use of accurate ephemeris in transporting coordinates to support points has no significant influence, since transportation with broadcast ephemeris also meets the accuracy requirements for the Standard Technique for Georreferencing Rural Properties. On the other hand, when GPS and GLONASS data were used, such combination provides the best results. In the case of neighboring points, the use of GPS and GLONASS data is also recommended because such data meet the precision requirement and showed better results than those from where data were processed separately.
