Resumo: O assentamento Sepé Tiaraju, situado na região canavieira de Ribeirão Preto (SP), constitui-se o primeiro na modalidade PDS (Projeto de Desenvolvimento Sustentável) no Estado de São Paulo e tem a Agroecologia como centro da matriz tecnológica. Dentro desta proposta, o uso de Sistemas Agroflorestais (SAFs) vem constituindo-se como uma alternativa de estímulo econômico à recuperação florestal e incorporação do componente arbóreo nos sistemas produtivos dos agricultores. Este trabalho visa levantar experiências de SAFs executadas pelos assentados em seus lotes e de como as práticas agroecológicas desenvolvidas pelos mesmos vêm contribuindo para a construção de um novo modelo de assentamento. A pesquisa, realizada por intermédio de técnicas de diagnóstico rural participativo, abrangeu um conjunto de 32 famílias. Observou-se que com diversificação dos cultivos nos SAFs os assentados aumentaram a estabilidade de seus agroecossistemas, resultando na menor dependência de insumos externos. Também se constatou estádios mais avançados da transição agroecológica alcançados por assentados que fazem uso de SAFs. Abstract: The settlement Sepé Tiaraju, located in the sugarcane region of Ribeirão Preto (SP), constitutes the first modality PDS (Project on Sustainable Development) in São Paulo and has agroecology as the center of the array technology. Within this proposal, the use of agroforestry systems (SAFs) is establishing itself as an alternative economic stimulus to forest restoration and incorporation of the tree component in the productive systems for farmers. This paper aims to raise the experiences of SAFs executed by the settlers on their lots and how farming practices developed by them have contributed to the construction of a new settlement model. The research, using techniques of participatory rural appraisal, covered a range of 32 families. It was observed that with increasing diversification of crops in agroforestry settlers increased the stability of agroecosystems, resulting in less dependence on external inputs. Also found that more advanced stages of agroecological transition is being made by settlers who use SAFs.

Brazil nut (Bertholletia excelsa Bonpl.) is considered the cornerstone non-timber species of Amazonian conservation. Nuts (or seeds) of this massive tree are harvested by local people living in and near old growth forests, supporting local livelihoods and regional economies. Secondary forests, however, particularly plots previously used for agriculture (swidden fallows), present better B. excelsa seedling and sapling recruitment than mature forest. This study examines the extent to which forest residents could increase nut productivity by allowing their fallows to grow into Brazil nut rich forests. We conducted B. excelsa inventories in the Brazilian state of Acre in abandoned swidden fallows of different ages. We also conducted interviews to determine landowner perspectives on the fallow potential for increasing nut production. An individual-based model, based on in-situ inventories and primary and secondary datasets from prior fieldwork, simulated growth, survivorship and production from the 250 inventoried trees in 18 fallows of varying sizes (from 0.41 to 4.18 ha) and different regrowth stages (12 to 60 years old). These simulation model predictions showed that after 10 years, 2.4% of existing trees would be productive, with an average of 68.6 ± 21.5 fruits per reproductively mature tree in the four fallows that most quickly yielded productive trees. By the final projected time interval (40 years), predictions suggest all fallows will produce fruits with cumulative production averaging 1475 ± 359 fruits ha?1, suggesting an increase in landowner income of US$55.1 ± 13.4 per hectare of fallow. Our simulation model is the first to explore fruit productivity of Brazil nut in secondary forest. It likely underpredicts B. excelsa growth and nut production, considering that swidden fallows provide better resource availability than the forest-derived datasets we used to construct the model equations. In conclusion, our findings support previous research that suggests that higher B. excelsa recruitment rates observed in abandoned swidden fallows could indeed translate into greater adult densities and thus potentially, higher nut production – a conclusion mirrored by most participant landowners.
