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.

São Francisco Valley (SFV) is located in Northeastern Brazil, in a tropical semi-arid region where one vine can produce two harvests per year, due to high temperatures, solar radiation rates, and irrigation throughout the year. This is the main characteristic iffering this from other winegrowing region in the world. The objective of this study was to characterize volatile profiles of sparkling wines produced by the traditional method, using Chenin Blanc and Syrah grapes, the two main varieties used for white and red wines, respectively, grown in the region. The sparkling wines remained on lees for six months maturing. The sparkling wines were characterized by the parameters density, pH, total titratable and volatile acidities, residual sugars, dry extract, alcohol content, total phenolic compounds, in vitro antioxidant activity and volatile fraction. The volatile fraction extraction was performed by the HS-SPME technique and tentative identification of the volatile compounds was carried out with GC-MS using the scan mode. A total of 33 volatile compounds were identified, among them 11 alcohols, 13 esters, five carboxylic acids, and four different chemical classes. The volatile profile of Chenin Blanc sparkling wine was associated mainly to 2,3-butanediol, 3-ethoxypropan-1-ol, diethyl succinate, and ethyl decanoate, while Syrah sparkling wine was characterized by benzaldehyde, butyric acid, and some acetates. This study reported for the first time volatile profiles of traditional sparkling wines from SFV, as new products, contributing to better understand the quality potential of these beverages for a tropical semi-arid region.
