Levantamento de reconhecimento de baixa intensidade dos solos da Reserva Extrativista do Alto Juruá, Marechal Thaumaturgo, Acre.

Este trabalho foi executado pela Universidade Federal do Acre (Ufac) em cooperação com a Fundação de Tecnologia do Estado do Acre (Funtac), Embrapa Acre e Universidade Estadual de Campinas (Unicamp). O levantamento de solos, em nível de reconhecimento de baixa intensidade, compreende a Reserva Extrativista do Alio Juruá, localizada entre as coordenadas geográficas de 08 0 45' e 09 0 45' 8, de latitude sul e 72 0 00' e 730 00' W, longitude a oeste. A metodologia utilizada é a mesma que a Embrapa Solos vem utilizando em estudos similares. Realizaram-se análises físicas e químicas no Laboratório de Solos da Embrapa Acre e as análises de ataque sulfúrico no laboratório da Embrapa Solos. No desenvolvimento da prospecção pedológica foram utilizadas imagens TM 345/Landsat - 5, 1992, tratadas no Laboratório de Processamento de Informações Georreferenciadas da Unicamp, na escala de 1:100.000 e 1:200.000. Os mapas finais de solos foram elaborados na escala de 1:250.000, com unidades de mapeamento em associações, dada a limitação da escala. Os principais solos encontrados na área são: Alissolos, Luvissolos, Cambissolos, Chemossolos, Gleissolos e Neossolos. Exduindo a alta fertilidade, os solos da Reserva Extrativista do Alto Juruá apresentam sérias restrições de uso quando se consideram as condições de relevo em que estão inseridos. A área apresenta relevo ondulado a forte ondulado e solos com alto gradiente textural, implicando em alta susceptibilidade à erosão. Observou-se, em algumas áreas de relevo forte ondulado e sobre a ocorrência de Cambissolo e floresta tropical aberta, erosão laminar ligeira. No caso de retirada da floresta natural, este processo erosivo irá se intensificar, causando danos irreversíveis ao solo e, conseqüentemente, ao ambiente.

A river of memory: landscape, narrative and identity in the Lee Valley, Co. Cork, Ireland

In moments of rapid social changes, as has been witnessed in Ireland in the last decade, the conditions through which people engage with their localities though memory, individually and collectively, remains an important cultural issue with key implications for questions of heritage, preservation and civic identity. In recent decades, cultural geographers have argued that landscape is more than just a view or a static text of something symbolic. The emphasis seems to be on landscape as a dynamic cultural process – an ever-evolving process being constructed and re-constructed. Hence, landscape seems to be a highly complex term that carries many different meanings. Material, form, relationships or actions have different meanings in different settings. Drawing upon recent and continuing scholarly debates in cultural landscapes and collective memory, this thesis sets out to examine the generation of collective memory and how it is employed as a cultural tool in the production of memory in the landscape. More specifically, the research considers the relationships between landscape and memory, investigating the ways in which places are produced, appropriated, experienced, sensed, acknowledged, imagined, yearned for, appropriated, re-appropriated, contested and identified with. A polyvocal-bricoleur approach aims to get below the surface of a cultural landscape, inject historical research and temporal depth into cultural landscape studies and instil a genuine sense of inclusivity of a wide variety of voices (role of monuments and rituals and voices of people) from the past and present. The polyvocal-bricoleur approach inspires a mixed method methodology approach to fieldsites through archival research, fieldwork and filmed interviews. Using a mixture of mini-vignettes of place narratives in the River Lee valley in the south of Ireland, the thesis explores a number of questions on the fluid nature of narrative in representing the story and role of the landscape in memory-making. The case studies in the Lee Valley are harnessed to investigate the role of the above questions/ themes/ debates in the act of memory making at sites ranging from an Irish War of Independence memorial to the River Lee’s hydroelectric scheme to the valley’s key religious pilgrimage site. The thesis investigates the idea that that the process of landscape extends not only across space but also across time – that the concept of historical continuity and the individual and collective human engagement and experience of this continuity are central to the processes of remembering on the landscape. In addition the thesis debates the idea that the production of landscape is conditioned by several social frames of memory – that individuals remember according to several social frames that give emphasis to different aspects of the reality of human experience. The thesis also reflects on how the process of landscape is represented by those who re-produce its narratives in various media.

Natural streamflow regime alterations: Damming of the Piave river basin (Italy)

A novel approach is proposed to estimate the natural streamflow regime of a river and to assess the extent of the alterations induced by dam operation related to anthropogenic (e.g., agricultural, hydropower) water uses in engineered river basins. The method consists in the comparison between the seasonal probability density function (pdf) of observed streamflows and the purportedly natural streamflow pdf obtained by a recently proposed and validated probabilistic model. The model employs a minimum of landscape and climate parameters and unequivocally separates the effects of anthropogenic regulations from those produced by hydroclimatic fluctuations. The approach is applied to evaluate the extent of the alterations of intra-annual streamflow variability in a highly engineered alpine catchment of north-eastern Italy, the Piave river. Streamflows observed downstream of the regulation devices in the Piave catchment are found to exhibit smaller means/modes, larger coefficients of variation, and more pronounced peaks than the flows that would be observed in the absence of anthropogenic regulation, suggesting that the anthropogenic disturbance leads to remarkable reductions of river flows, with an increase of the streamflow variability and of the frequency of preferential states far from the mean. Some structural limitations of management approaches based on minimum streamflow requirements (widely used to guide water policies) as opposed to criteria based on whole distributions are also discussed.
