A agroecologia como estratégia de gestão de Unidades de Conservação de Uso Sustentável no Vale do Ribeira − SP, Brasil / Agroecology as a management strategy for Sustainable Conservation Units in Vale do Ribeira – SP, Brazil

Narezi, Gabriela 05 November 2012 (has links)
Este trabalho apresenta elementos de reflexões acerca dos distintos modelos de gestão que são concebidos para as áreas naturais protegidas. Nosso interesse se voltou, em particular, para os debates acerca das Unidades de Conservação de Uso Sustentável do estado de São Paulo - Brasil. Atualmente, na região do Vale do Ribeira, possuidora de um dos maiores remanescentes contínuos de Mata Atlântica do país, é possível encontrar disputas por diferentes modelos de gestão destas áreas. O estudo da implantação das Reservas de Desenvolvimento Sustentável (RDS) permite analisar as mais recentes formas de reconhecimento do direito de permanência de populações tradicionais no interior de áreas naturais protegidas no Brasil, em especial, na faixa de Mata Atlântica do litoral sul paulista. Nesta perspectiva, buscou-se analisar a inserção da temática da agroecologia como estratégia de gestão, em meio a conflitos socioambientais. A metodologia de pesquisa comportou levantamento bibliográfico e coleta de dados primários, graças a anotações em cadernos de campo, obtenção de relatos orais nos espaços participativos de gestão e uso do território da RDS do Despraiado, no âmbito da recategorização da Estação Ecológica Juréia-Itatins em mosaicos de UCs e entrevistas semi-estruturadas junto aos gestores e pesquisadores das UCs do Vale do Ribeira. A pesquisa ainda contou com um estágio doutoral no Institute des Hautes Études sur l\'Amerique latine, Sorbonne Nouvelle, onde foi possível analisar as estratégias de gestão territorial adotadas em dois Parques Naturais Regionais franceses, consideradas enquanto subsídio para nossa análise sobre a conciliação da conservação com o desenvolvimento. A partir dos dados coletados foi possível caracterizar e interpretar a organização social, o histórico das práticas produtivas agrícolas tradicionais, os conflitos socioambientais ligados à gestão da RDS do Despraiado e as práticas agrícolas intensivas em áreas degradadas. Neste quadro, foi possível encontrar evidências de que o modo de vida e de produção agrícola favorecem uma sensibilidade das populações locais ao início de um processo de transição agroecológica. Entretanto, as disputas em torno da implantação da RDS em estudo aqui revelam que a perspectiva de conservação da natureza com desenvolvimento - na qual a agroecologia está, em princípio, em primeiro plano - enfrenta muitos obstáculos para sua disseminação. A promulgação da Ação Direta de Inconstitucionalidade contra a lei que instituiu o Mosaico de UCs Juréia-Itatins reforça a manifestação dos interesses preservacionistas no âmbito da gestão deste território no estado de São Paulo. Mesmo com a repercussão de experiências agroecológicas de sucesso no Vale do Ribeira, ainda são muito incipientes as iniciativas de conservação da sociobiodiversidade e de valorização cultural para o desenvolvimento sustentável das populações tradicionais no interior de UCs paulistas. / This paper presents reflections regarding different management models designed for protected natural areas. Our research is particularly focused in debates about Sustainable Conservation Units in Sao Paulo State in Brazil. Vale do Ribeira is an area that has one of the largest continuous remnants of Atlantic Rainforest of the country. There are several disputes over different management models for those areas. The study of Sustainable Development Reserves (Reservas de Desenvolvimento Sustentável - RDS) implementation allows analyzing the latest forms of recognition of the right of residence of traditional populations within protected natural areas in Brazil, especially in the Atlantic rainforest in the southern coastal area of Sao Paulo state. In this perspective, this study sought to analyze the integration of agroecology as a management strategy amid environmental conflicts. The research methodology included bibliographic analysis and collection of primary data through field notes; oral histories obtained in management and land use participatory spaces at Despraiado RDS in the context of restructuration of Juréia- Itatins Ecological Station in Conservation Units Mosaics; and semi-structured interviews with the managers and researchers of Vale do Ribeira Conservation Units. The research also included a doctoral internship at Institute des Hautes Études sur l\'Amerique latine, at Université Sorbonne Nouvelle, in France where it was possible to analyze the strategies of land management practices of two French Regional Natural Parks. That experience was the base to analyze the conciliation between conservation and development in this study. From the data collected it was possible to characterize and interpret the social organization, the history of traditional agricultural production practices, of environmental conflicts related to the management of Despraiado RDS and intensive agricultural practices in degraded areas. In this context, it was possible to find evidence that the way of life and agricultural production of the area favor local sensitivity in regard of an agroecological transition process. However, the disputes over the implementation of the RDS analyzed in this study, shows that the perspective of nature conservation along with development faces many obstacles to its propagation even though agroecology is in the forefront of the discussion. The enactment of the lawsuit declaring the creation of Juréia-Itatins Conservation Unit Mosaic an unconstitutional act, reinforces the manifestation of preservationists\' interests in the management of this Sao Paulo State territory. Even with the impact of successful agroecological experiences at Vale do Ribeira, socio-biodiversity conservation initiatives and cultural valorization of sustainable development of traditional populations are still rudimentary at Conservation Units in the State of Sao Paulo.

FraÃÃes hÃmicas em luvissolos sob diferentes sistemas agroflorestais no municÃpio de Sobral - CE / The humic fractions of a Luvissol under different agroforestry systems in the city of Sobral

Gislane Mendes de Morais 07 October 2007 (has links)
InvestigaÃÃo desenvolvida em sistemas agroflorestais que estÃo sendo testados no semi-Ãrido cearense, comparativamente a um sistema de cultivo convencional da regiÃo, identificou o aumento dos teores das fraÃÃes Ãcidos fÃlvicos (FAF) e hÃmicos (FAH). Estes resultados estÃo associados Ãs condiÃÃes em que houve revolvimento do solo como acontece nos sistemas agrossilvipastoril e convencional, o que podem ser atribuÃdos a uma possÃvel conversÃo da fraÃÃo humina em Ãcidos fÃlvicos e hÃmicos. Para testar essa hipÃtese, o presente trabalho objetivou caracterizar as fraÃÃes hÃmicas do Luvissolo, dos seguintes tratamentos: Agrossilvipastoril (AGP), Silvipastoril (SILV), Cultivo Intenso em Pousio (CIP), Mata Nativa 1 (MN1) e Mata Nativa 2 (MN2), nas profundidades 0 â 6 e 6 â 12 cm. Foram realizadas caracterizaÃÃes das fraÃÃes Ãcidos fÃlvicos e hÃmicos atravÃs das anÃlises termogravimÃtricas, elementar, ultravioletavisÃvel e infravermelho. Os resultados de todos os tratamentos analisados indicaram que os Ãcidos hÃmicos mostraram-se mais resistentes que os Ãcidos fÃlvicos. Analisando os tratamentos, o SILV apresentou fraÃÃes hÃmicas menos resistente do que os outros tratamentos estudados. O tratamento AGP apresentou fraÃÃes hÃmicas mais humificadas, podendo ser mais recalcitrante. Este fato pode estar relacionado, devido o tratamento AGP sofrer impacto pelo manejo adotado, o que nÃo acontece no tratamento SILV. Confirmando a hipÃtese de que o ambiente solo em sistemas de manejo que sofrem intensa perturbaÃÃo està sendo degradado. / Investigations about agroforestry systems, which has been carried out in the arid region in Ceara, Brazil, comparatively to a conventional tillage system in the same area, showed an increase in the concentration of fulvic fraction (FAF) and humic acid (FAH) fractions. These results are related to the conditions in which soil was plowed similar to what is usually done in agrosilvopastoral and conventional systems, which might be attributed to a possible conversion of the humin fraction into FAF and FAH. To address to this hypothesis, a field experiment was carried out aiming to characterize the humic fractions of a Luvissol, over the following treatments: Agrosilvopastoral system (AGP), Silvopastoral system (SILV), Fallow conventional tillage (CIP), Native forest 1 (MN1) and Native forest 2 (MN2), at the depths of 0 to 6 and 6 to 12 cm of the soil. Termogravimetric, elemental, visible-ultraviolet and infrared analyses were utilized to characterize FAF and HAF in the soil samples. The results showed humic acids to be more resistant than fulvic acids. Silvopastoral system had its FAH less resistant in comparison to the others. The AGP had the FAH more humified, which may be more recalcitrant. This finding might be related, due to the AGP to overgo impact by the adopted management, what does not take place in the SILV, so that it might confirm the hypothesis that soil environment overgoing intense disturb might be under degradation.

It attempts to find the theoretical-methodological guidelines of an innovative pedagogical praxis. This was done by accompanying the educational experiences of subjects from traditional communities in the Southern region of the state of Rio de Janeiro (Costa Verde), who are continually educated in agroecology. Agroecology establishes relationships with environmental education when it discusses ecological actions from a productive and agricultural perspective, as a way of attaining social-cultural reorganization of these communities. The research is qualitative, along an ethnographic model, with a bibliographical review from an anthropological perspective, of formative processes, agroecology, environmental education, educational paradigms and theory of complexity. Based on experiences of immersion in ecological sites and indigenous villages, and detailed interviews with quilombola subjects and family farmers about education and the relationship with nature, the work presents and discusses experiences and routes that antagonize the hegemonic paradigm, defending the idea that, in order to construct ecological knowledge, one needs to revalue and renew proposals, principles and modes of action to allow the reconstruction of the world under new forms of society-nature relationships / O presente trabalho acompanha processos formativos de educadores ambientais que seguem princ?pios educativos de transforma??o das rela??es socioambientais com o objetivo de resgatar o ?ser natural?.

Agriculture and the environment : an economic-ecologic input-output model of the Canadian economy

Carpentier, Line Chantal January 1994 (has links)
The current environmental movement calls for a re-evaluation of many economic-ecologic relationships. The objective of this study is to identify industrial sectors and final demands most responsible for particular types of residual discharge and resource use. An economic-ecologic model was constructed for the Canadian economy from the Statistics Canada I-O as modified by Thomassin et al. (1992). This modified version with its 12 agricultural sectors and 16 food processing sectors is best suited for agricultural policy analysis. The model estimates national erosion, pesticide and fertilizer use as well as air and water pollutants, solid waste, and water use associated with specified economic activities. / Two different scenarios were analyzed. In the first, the impact on both the economy and the environment from changes in the final demand for agricultural and food commodities was simulated. Each commodity's final demand was increased by $1 million and its impact compared to the other simulated results. The ten commodities studied yielded similar economic impacts, while their environmental impacts differed considerably. Changes in the demand for wheat and oilseeds had the largest environmental impacts. / In the second scenario, the effects of a $1 million increase in each final demand category were compared. This scenario focussed on markets rather than products. The construction, exports and personal expenditures categories were the greatest generator of wastes and the largest user of free resources. The exports category yielded twice as much erosion than personal expenditures and twenty times more than the next highest value (construction).

The effect of climate and aerosol on crop production: a case study of central Asia

Ozdes, Mehmet 10 July 2012 (has links)
The effect of recent climate change in Central Asia poses a significant and potentially serious challenge to the region’s agricultural sector. An investigation of the aerosol-climate- crop yield correlation in this region is essential for a better understanding of the effect of aerosols and climate on Central Asian agriculture. Our goal is to investigate the linkages between aerosol, climate and major crop production (cotton, maize, wheat, and rice) in specified agricultural regions in the five Central Asian countries. Our approach is to perform the Pearson’s Correlation Coefficient analysis in order to observe the statistical correlation between crop yield, temperature, precipitation, and aerosol optical depth (AOD), for each indicated agricultural region in the selected countries. Besides, using NASA GIOVANNI website tools, we retrieve distribution maps and time series of temperature, precipitation and AOD to facilitate the analyses. The research shows that in some aspects, the relation between AOD, climate, and crop yield is different in Central Asia than in previous global or large scale research hypotheses. The statistical correlations vary not only across countries but also across agricultural regions. For example, in Kazakhstan, opposite correlations exist between precipitation and AOD in two different agricultural regions even though both regions are rain-fed. In the more arid countries (with lower rain rates) such as Turkmenistan and Uzbekistan, no correlation exists between crop production and temperature, precipitation, and AOD, while the less arid (with higher rain rate) countries (Kazakhstan, Kyrgyzstan, and Tajikistan) indicate a positive correlation.

Optimising habitat creation for woodland birds : the relative importance of local vs landscape scales

Whytock, Robin C. January 2018 (has links)
Global land-use change and industrialisation has driven biodiversity declines and impaired ecosystem functioning. Recently, there have been large-scale efforts to not only halt habitat loss but create and restore habitat on formerly managed (e.g. agricultural) land. However, although the effects of habitat loss and fragmentation on biodiversity are well understood, our understanding of how biodiversity responds to habitat created in a patchy configuration is not. In particular, little is known about the relative importance of local (e.g. patch size) vs landscape scales (e.g. amount of habitat in the landscape) for restoring biodiversity in created habitat. Here, a long-term, large-scale natural experiment (the Woodland Creation and Ecological Networks project) was used to understand how bird species, communities and behaviour respond to woodland created in a patchy configuration on post-agricultural land. I used a combination of direct and indirect survey methods to quantify bird diversity, abundance and vocal behaviour in post-agricultural woodlands of known age in Great Britain. I show that secondary woodlands favour generalist species and older patches contain more individuals and species due to their vegetation structure. In relative terms, local-scale factors such as patch size made the greatest contribution to bird diversity and abundance. Colonisation events drive community assembly in new habitat, and I found that large-scale (km2) habitat patterns were more important than patch-level factors during colonisation of breeding territories by a long distance migrant bird (Willow Warbler Phylloscopus trochilus). Land management practices surrounding a habitat patch can also affect its perceived quality and relative attractiveness to potential colonisers. Using the Eurasian Wren Troglodytes troglodytes as a model species, I found that high proportions of agricultural land at woodland edges caused an increase in perceived predation risk. In conclusion, I suggest that post-agricultural woodlands rapidly provide valuable habitat for generalist woodland birds. Local, patch-level factors (area, vegetation structure) also appear relatively more important than landscape factors for woodland bird communities. Land-managers seeking to maximise the benefits of woodland creation for birds should thus focus on creating large patches with a diverse vegetation structure.

Proposta de uma metodologia de ensino sobre aplicações da função afim a partir de situações problemas relacionados à agroecologia

Funez, Edenilson 11 October 2017 (has links)
Este trabalho busca investigar a viabilidade de uma proposta de metodologia de ensino sobre aplicações da função afim a partir de situações didáticas relacionadas à agroecologia. As situações didáticas desenvolvidas, tem como base a Teoria das Situações Didáticas de Guy Brousseau, onde os alunos constroem o conhecimento através de situações didáticas e/ou adidáticas, a partir das dialéticas de ação, formulação, validação e, institucionalização. Utilizou-se como metodologia de pesquisa a Engenharia Didática de Artigue. A proposta foi aplicada em uma turma do primeiro ano do ensino médio da Casa Familiar Rural de São Jorge d‟Oeste, onde os alunos estudam em regime de alternância e tem como escola base o Colégio Estadual Padre José de Anchieta de São Jorge d‟Oeste. Percebeu-se através dos registros dos alunos que houve um desenvolvimento dos alunos no que diz respeito a se expressar matematicamente. Logo, pode-se concluir que as situações didáticas contribuíram para o ensino aprendizagem dos alunos, assim como o contexto das atividades relacionado à agroecologia também possibilitou a troca de experiências com os familiares dos mesmos. Além disso, a Teoria das Situações Didáticas e a Estruturação do Milieu (Meio) deram suporte para o estudo das diversas relações entre o conhecimento ou saber, os alunos e, as relações entre o próprio conhecimento ou saberes e, as situações. / This work seeks to investigate the feasibility of a teaching methodology proposal on applications of related function from didactic situations related to agroecology. The didactic situations developed are based on Guy Brousseau's Theory of Didactic Situations, where students construct knowledge through didactic and / or aditional situations, from the dialectics of action, formulation, validation and institutionalization. Artigue didactic methodology was used as research methodology. The proposal was applied in a class of the first year of high school of the Casa Familiar Rural de São Jorge d'Oeste, where the students study in alternation regime and has as base school the Colégio Estadual Padre José de Anchieta de São Jorge d'Oeste. It was noticed through the records of the students that there was a development of the students in regard to expressing mathematically. Therefore, it can be concluded that didactic situations contributed to the teaching of student learning, just as the context related to agroecology contributed to the exchange of experiences with their families. In addition, the Theory of Didactic Situations and the Structuring of the Milieu (Medium) gave support to the study of the various relationships between knowledge or knowledge, students and the relations between the knowledge itself or knowledge and the situations.
