Resource-dependent livelihoods and the natural resource base

The natural resource base, terrestrial and marine, provides rural households in lower-income countries with income, food, shelter, and medicines, which are variously gathered and hunted in common lands and waters. These resources may be actively managed, whether by the government or local community; or may be de facto open access, with little effort by governments to prevent what may be de jure illegal extraction. This paper provides an appraisal of the literature that encompasses the direct value of wild resources to rural households; the extent to which these resources mitigate poverty and inequality; and the importance of the institutional context. The literature is increasingly addressing competing demands on the resource base both to support nearby livelihoods, and to enhance ecosystem services such as biodiversity; and how initiatives such as community-based payments for ecosystem services are changing how people interact with the resource base.

Effectiveness of artemether-lumefantrine provided by community health workers in under-five children with uncomplicated malaria in rural Tanzania : an open label prospective study

Background: Home-management of malaria (HMM) strategy improves early access of anti-malarial medicines to high-risk groups in remote areas of sub-Saharan Africa. However, limited data are available on the effectiveness of using artemisinin-based combination therapy (ACT) within the HMM strategy. The aim of this study was to assess the effectiveness of artemether-lumefantrine (AL), presently the most favoured ACT in Africa, in under-five children with uncomplicated Plasmodium falciparum malaria in Tanzania, when provided by community health workers (CHWs) and administered unsupervised by parents or guardians at home. Methods: An open label, single arm prospective study was conducted in two rural villages with high malaria transmission in Kibaha District, Tanzania. Children presenting to CHWs with uncomplicated fever and a positive rapid malaria diagnostic test (RDT) were provisionally enrolled and provided AL for unsupervised treatment at home. Patients with microscopy confirmed P. falciparum parasitaemia were definitely enrolled and reviewed weekly by the CHWs during 42 days. Primary outcome measure was PCR corrected parasitological cure rate by day 42, as estimated by Kaplan-Meier survival analysis. This trial is registered with ClinicalTrials.gov, number NCT00454961. Results: A total of 244 febrile children were enrolled between March-August 2007. Two patients were lost to follow up on day 14, and one patient withdrew consent on day 21. Some 141/241 (58.5%) patients had recurrent infection during follow-up, of whom 14 had recrudescence. The PCR corrected cure rate by day 42 was 93.0% (95% CI 88.3%-95.9%). The median lumefantrine concentration was statistically significantly lower in patients with recrudescence (97 ng/mL [IQR 0-234]; n = 10) compared with reinfections (205 ng/mL [114-390]; n = 92), or no parasite reappearance (217 [121-374] ng/mL; n = 70; p <= 0.046). Conclusions: Provision of AL by CHWs for unsupervised malaria treatment at home was highly effective, which provides evidence base for scaling-up implementation of HMM with AL in Tanzania.

Por que é cidadão o jornalista-cidadão?: História das mídias e jornalismo cidadão de base comunitária na Maré

Afinal, por que é cidadão o jornalista cidadão? Foi esta a pergunta que desencadeou todo um esforço de pesquisa no sentido de identificar práticas comuns nas diferentes experiências de jornalismo cidadão. Para desenvolver e tentar ampliar o conceito trabalhado, a opção foi de analisar o espectro da comunicação comunitária, sobretudo em veículos que tiveram origem na área da Maré, no Rio de Janeiro, nas últimas três décadas. Assim, mapeando algumas dessas experiências e selecionando casos entre os que chamaram mais atenção pela propriedade com que trabalham os aspectos relacionados ao jornalismo cidadão, esta dissertação se detém sobre o significado da cidadania para o cidadão-jornalista e a contribuição à identidade local prestada pela comunicação comunitária. Minha idéia é demonstrar como experiências deste gênero são capazes de não apenas de pautar meios tradicionais de mídia, mas sobretudo de ajudar a estabelecer dentro da própria comunidade uma cultura de mídia e uma esfera pública local, desenvolvendo uma reapropriação da identidade da favela e de seus moradores e contribuindo para a busca e/ou exercício da cidadania.

Um olhar sobre o patrimônio histórico-arquitetônico de Assú/RN: análise com base na percepção dos usuários e no ponto de vista técnico

This research analyzes the actual Historic-Architectural Heritage of Assú City which is located in Rio Grande do Norte State, Brazil, the study is based on both Assú s residents perception and technician s viewpoint. It looks forward to expose this community s relationship with the existing number of historic buildings, the scale of people s identity to the place and the association of this perception toward the preservation and conservation s scale of the historic settlement. Since the contextualization of the degradation s process of central areas, the study draw nea initially the conceptual aspects, focusing on the debate about heritage and the preservationist practice. The work complements the discussion through an approach on people-environment relationship and environmental perception, considering relevant factors for planning process. The obtained and presented data had diagnosed the condition of the architectural pile and also allowed this work to formulate recommendations for the studied area and architectural set in order to contribute for future urban politics implementation that consider the building, which are not only important to the considered population, but to the Rio Grande do Norte s History, as well

Uma ecologia de base complexa

This thesis objective systemize and discuss the ecological knowledge constructed by means of tradition knowledge with basis in a complex ecology (MORIN, 2002b). The conception of tradition knowledge (ALMEIDA, 2001c) corresponds to a diversity of knowledgement, of men and women, constructed from heteroclite elements of the geographic way, making use of analogies and homologies which serves as the base for this scientific inquiry. These knowledge are extremely related the context where these people are inserted. To construct an ecology of complex base is to understand that the reality is not given previously, and that its construction assumes indissociability among the elements that composes it, that is, between nature and society, material and immaterial elements. To incorporate the disorder, the uncertainty, the unpredictable and the auto-echo-organization as guide principles of a new ecology, constitutes in a new vision of the biological science and the scientific ecology in direction to a science of complexity. The work focuses the ecological knowledge of the Piató lagoon, municipality of Açu, in the State of Rio Grande do Norte, having as interlocutor of this boarding Mr. Francisco Lucas da Silva (known in the local as Chico Lucas), fisherman and agriculturist, who was born, and lives until today, in the community of Areia Branca, around the lagoon. Having for base the method as strategy (MORIN, 2001a), the research construction was performed through the realization of more than 10 trips carried out between the years of 2005 and 2007. In these trips the ecological aspects of the environments such as, the flora and the fauna, as well as the environmental impacts on the lagoon, were obtained in recorded dialogues and interviews with Chico Lucas, which were later transcripts. The information from there showed a natural and social complex reality, little known by Cartesian science, since it brings a wealth of details of daily life full, over all, for tradition knowing of the people that had lived there and the ones who remain living there. The thesis looks to understand the strategies of thought and the knowledge production referring to traditional knowing and its ability of interchange between different cognitive operators. The ecological knowledge that emerges of these knows reveals a systemic perception of the environment, presenting the beings and phenomena in its peculiarities and its degrees of complexity, but immutable in its indissociability

O turismo de base local como um possível indutor de desenvolvimento rural: uma análise da realidade e das potencialidades no distrito de dondo-moçambique

The current debate on rural development focuses on the territorial approach, recognizing the multifunctional character of rural areas. Emphasize the use of endogenous forces, the need of implement policies which valorize local specificities, the participation of social actors in revitalization of rural areas. In this context tourism enters as a means to induce a new dynamic to rural areas, since the activity is regarded as a channel for the upgrading of the natural and cultural resources and the rural way of life. This study focuses on local-based tourism as a promoter of rural development, giving an analysis of the social reality and potential for this tourism in the district of Dondo. In it, is proposed to analyze the potential for development of local-based tourism in the district of Dondo, assessing the extent to which local reality enables the inclusion of the community in the management of local tourism resources. For this, was showed the inclusion of local-based tourism in the current context of rural development, was identified and organized systematically the factors that influence the implementation of local-based tourism in the study area and was verified as far as possible the study area corresponds to the constraints identified, showing how local-based tourism can best been encouraged. Was adopted a qualitative methodological approach to both the procedures and data processing, but also by critical approach, using bibliographical research, semi-structured interviews that fell on the group of public administrators who work in tourism and community leaders. The critical analysis was based on the principles of sustainability o Sachs particular ecological, social, cultural, economic, space, beyond the analysis of political and institutional aspects. The survey results show that the district of Dondo has a potential for implementing a model of tourism development on a local basis, since it is rich in natural and cultural research, benefits from good network accessibility in the context of the market in the region, the population live according to their habits and customs and value their identity. There is also a good cooperation between community members, although not in tourism, a fact which is observed through the lever of community participation in associations, cooperatives, working in areas such as agriculture, fishing, environment, civic education etc. It also has public funding sources to augment or stimulate local investment. Despite obstacles such as inexistence of policies and local plans for tourism development, lack of awareness of tourism, lack of basic infrastructure, as well as equipment and facilities to support tourism, the results shows that these problems can be solved through a public commitment from both government, and community through a joint planning and participation

Crítica ao fundacionismo cartesiano com base no argumento contra a linguagem privada

This assignment ains to prove the pertinency of using the wittgenstein´s argument against private language as a criticism to cartesian fundacionism. Therefore, I want to demonstrate in the first chaper the conceptual viability of facing the cartesian argument of cogito not as a simple silogism but as an exemple of a private experience (process of thinking). At the second chaper, the subordination of the argument against private language give us the idea that rules can only be followed by means of corrections givem by a linguistic community that is external to the private subject, in a way to be unviable the assumption that is possible to name an internal experience without searching external rules of the use of terms. At the chaper 3 the pertinency of the hypothesis raised by A. Kenny, about the overtaking of the argument against private language can be extended to the idea of epistemic and ontologic privacy that would lend validity to the fundacion present at the argument at the cartesian cogito. In oder to become evident the pertinency of use of Wittgenstein´s argument agaist Descartes´ fundation, it´s necessary, at the chaper 3, to demonstrate the impertinency of the objection to the A. Kenny´s hypothesis, based on the experiency of the thought of the brain at the recipient, to make clear the incompatibility existing between the cartesian idea of cogito and Wittgenstein´s notion that language is an activitie followed by rules, wich correction criterion may be external and intersubjective

Práticas de ensino-aprendizagem com base em cenários reais

O processo ensino-pesquisa-extensão realizado com a imersão dos sujeitos em cenários reais possibilita a integração universidade-comunidade, ampliando a inserção social. O objetivo deste trabalho foi apresentar a experiência de um projeto conduzido em cinco municípios brasileiros, com a participação de docentes, pós-graduandos e acadêmicos, em parceria com prefeituras municipais e trabalhadores de saúde como cenário de ensino-pesquisa no SUS. Foram realizadas oficinas e cursos de capacitação com as equipes de saúde, gestores e conselheiros de saúde, visitas técnicas aos municípios para avaliação situacional e supervisão das atividades, avaliação da satisfação dos usuários e formação de lideranças populares. Observou-se a melhoria na organização dos serviços e estímulo ao fortalecimento do vínculo entre os usuários e prestadores de serviços. Essa experiência serviu como laboratório de aprendizagem e pesquisa, fazendo-se ciência a partir da vivência in loco da realidade do SUS e contribuindo para uma formação professional mais humanitária baseada em cenários reais.

Effects of flooding regime and woody bamboos on tree community dynamics in a section of tropical semideciduous forest in South-Eastern Brazil

The influence of a population of the understorey woody bamboo Merostachys riedeliana and different flooding regimes on tree community dynamics in a section of tropical semideciduous forest in South-Eastern Brazil was examined. A forest section with an area of 1.6 ha composed of 71 adjacent plots was located on a slope ending at the river margin. The section was divided into five topographical sectors according to the mean duration of river floods. In 1991 and 1998 all trees with a diameter at the base of the trunk greater than or equal to 5 cm were measured, identified and tagged, and all live bamboo culms were counted. Annualised estimates of the rates of tree mortality and recruitment, gain and loss of tree basal area, and change in bamboo density were calculated for each of the 71 plots and five topographical sectors as well as for diameter classes and tree species. To segregate patterns arising from spatially autocorrelated events, geostatistical analyses were used prior to statistical comparisons and correlations. In general, mortality rates were not compensated by recruitment rates but there was a net increase in basal area in all sectors, suggesting that the tree community as a whole was in a building phase. Tree community dynamics of the point bar forest (Depression and Levee sectors) differed from that of the upland forest (Ridgetop, Middle Slope and Lower Slope sectors) in the extremely high rates of gain in basal area. The predominant and specialised species, Inga vera and Salix humboldtiana, are probably favoured by relaxed competition in an environment stressed by long-lasting floods. In the upland forest, mortality rates were highest at the Middle Slope, particularly for smaller trees, while recruitment rates were lowest. As bamboo clumps were concentrated in this sector, the locally higher instability in the tree community probably resulted from the direct interference of bamboos. The density of bamboo culms in the upland forest was negatively correlated with the rates of tree recruitment and gain in basal area, and positively correlated with tree mortality rates. Bamboos therefore seemed to restrict the recruitment, growth and survival of trees.

Uma escola para homem rural: a cultura popular, os camponeses e o movimento de educação de base (1960-1964)

Nos idos dos anos 1960, a intervenção sobre a cultura popular tornou-se um suposto da ação política de agentes modernizadores da sociedade brasileira. Por meio da Conferência Nacional dos Bispos do Brasil (CNBB), a Igreja Católica elaborou um projeto educacional de dimensão nacional, articulando suas emissoras de rádio no território brasileiro aos centros de educação radiofônica rural e criando, em 1961, o Movimento de Educação de Base (MEB). Os pressupostos teóricos e filosóficos do Movimento transcendiam as questões do aprendizado formal e pautavam-se por estratégias de ação da Igreja sobre os problemas de crescimento econômico e desenvolvimento social das regiões pobres brasileiras. O artigo em questãoversa sobre o camponês que participou do MEB e suas experiências escolares, avaliando os preceitos de educação rural, educação cívica e alfabetização de adultos propostos na ação dos agentes e das instituições modernizadoras do campo brasileiro. Analisamos os processos de assimilação e resistência do camponês aos princípios e projetos modernizantes externos à sua cultura. Novos ritmos de tempo, novas representações e novos significados foram introduzidos pela escola sobre práticas culturais seculares do campesinato brasileiro. No MEB, tal fenômeno resultou tanto na assimilação dos novos estímulos trazidos pela escola, quanto na insurreição de costumes e hábitos interligados às funções ritualísticas e costumeiras do indivíduo e/ou da comunidade rural.

Variations in tree community composition and structure in a fragment of tropical semideciduous forest in southeastern Brazil related to different human disturbance histories

In an area of tropical seasonal semideciduous forest, the soil characteristics, floristic composition, physiognomic structure, and the distribution of three regeneration and three dispersal guilds were studied for four stands within the forest that had documented histories of varying degrees of human disturbance. The aim was to study forest regeneration in areas of preserved forest and secondary forest, with parts of both types of forest experiencing either 'intensive' or 'occasional' cattle trampling. The study was carried out in the Sebastiao Aleixo da Silva Ecological Station, Bauru, São Paulo State, Brazil. Two stands were called 'secondary' because they corresponded to forest tracts that were felled and occupied by crops and pastures in the past and then abandoned to forest regeneration ca. 40 years before this study. The other two stands, called 'preserved', corresponded to areas of the fragment where the forest has been maintained with only minor human impacts. The arboreal component of the tree community (diameter at breast height or dbh greater than or equal to 5 cm) was sampled in 20 plots of 40 m x 40 m, and the subarboreal component (diameter at the base of the stem or dbs < 5 cm and height greater than or equal to 0.5 m) in subplots of 40 m x 2 m. Physiognomic features, such as canopy height and density of climbing plants, were registered all over a 5 m x 5 m gridline laid on the sample plots. Soil bulk samples were collected for chemical and textural analyses. Most detected differences contrasted the secondary to the preserved forest stands. The soils of the secondary stands showed higher proportions of sand and lower levels of mineral nutrients and organic matter than those of the preserved stands, probably due to higher losses by leaching and erosion. Compared to the secondary stands, the preserved ones had higher proportions of tall trees, higher mean canopy height, lower species diversity, higher abundance of autochorous and shade-tolerant climax species, and lower abundance of pioneer and light-demanding climax species. Despite the high proportion of species shared by the preserved and secondary stands (108 out of 139), they differed consistently in terms of density of the most abundant species. on the other hand, the secondary and preserved stands held similar values for tree density and basal area, suggesting that 40 years were enough to restore these features. Effects of cattle trampling on the vegetation were detected for the frequency of trees of anemochorous and zoochorous species, which were higher in the stands under occasional and intensive cattle trampling, respectively. The density of thin climbers was lower in the stands with intensive trampling. (C) 2004 Elsevier B.V. All rights reserved.
