Integração e recuperação paisagística em pedreiras

Esta dissertação, elaborada no âmbito da obtenção do grau de mestre em Arquitetura Paisagista, tem como tema a “Integração e Recuperação Paisagística em Pedreiras”, a qual foi desenvolvida com base no trabalho de investigação desenvolvido, enquanto colaborador no Centro Tecnológico da Pedra Natural de Portugal (CEVALOR) localizado em Borba, desde o ano 2000, até à atualidade. A recuperação de pedreiras pode ser caracterizada, como um processo de intervenção local, inserido no âmbito da gestão visual, da conservação e de valorização da paisagem. Para realizar o processo de recuperação, não só é necessário o correto enquadramento legal, como entender o contexto paisagístico, que permite avaliar os impactes visuais potenciais e propor medidas de mitigação adequadas. O conteúdo metodológico desta dissertação apresenta a análise, interpretação e caracterização estrutural da paisagem assim como da avaliação do impacte visual, assim como as opções de recuperação com vista à sua integração das pedreiras na paisagem; Abstract: Integration and landscape reclamation in quarries This dissertation concerning the theme “landscape integration and rehabilitation of quarries” aims to obtain the master degree in landscape architecture, as the result of my research as a collaborator at CEVALOR since the year of 2000. The integration and rehabilitation of quarries can be described has a process of local intervention within the fields of visual management, conservation and amelioration of the landscape. In order to accomplish the rehabilitation process, not only is necessary to consider all legal obligations but understand the landscape context, through the analysis of the visual quality and the assessment of the visual impacts in order to propose the most adequate mitigation measures. This dissertation presents a methodological approach that describes the process of landscape analysis, landscape visual impact assessment and the feasible rehabilitation options regarding the visual integration of quarries in the landscape.

QUALITY OF 'SWEETHEART' CHERRY UNDER DIFFERENT STORAGE CONDITIONS

Abstract: In Portalegre, Portugal, sweet cherry production is very important to the region’s economic sustainability. The sweet cherry ‘Sweetheart’ has exhibited short shelf life in spite of being highly appreciated by consumers due to its organoleptic characteristics. In this trial, we evaluated fruit quality of ‘Sweetheart’ stored under different storage conditions: 1) cold conditions (1ºC and high humidity 95%), 2) cold conditions and polypropylene film bags (MA), and 3) controlled atmosphere (CA) (1°C, 95% humidity, 10% CO2 and 8% O2). Fruit physical and chemical parameters were evaluated after 0, 6, 13, 20 and 27 days of cold storage. Quality parameters tested included weight loss, external colour (L* a* b*), visual assessment of the epidermis, epidermis and mesocarp penetration test, soluble solids content (SSC), and titratable acidity (TA). We also performed sensory analyses. The results for textural properties, colour coordinates and sensory analysis suggest that ‘Sweetheart’ fruit can be stored under cold conditions, 1°C, 95% humidity, for up to 21 days without significant loss of quality. Controlled atmosphere maintained tissue turgidity during storage; however, this was not noticed by the panelists, who consistently classified fruits stored under CA conditions with lower overall ratings than fruits under cold conditions with or without film bags.
