Análise de vários factores que influenciam a definição das chaves do território: o caso da freguesia de Cernache do Bonjardim

A Freguesia de Cernache do Bonjardim é limitada a norte e a oeste pelo Rio Zêzere e a sul pela Ribeira da Sertã, que constituem uma fronteira natural com os Concelhos de Figueiró dos Vinhos e Ferreira do Zêzere e a Freguesia de Palhais; a este confina com a Freguesia do Castelo, Cabeçudo e Nesperal. Percebe-se claramente o factor condicionante que são as barragens da linha do Zêzere na vivência e desenvolvimento das aldeias. O património foi limitado pelos factores naturais e, obviamente, os factores humanos. Existe uma diferença no povoamento das aldeias situadas em zonas acidentada e em zonas planas. Isto apresenta ligações com o tipo de orografia, de geologia, de solo, com o tipo de utilização desse solo e com o espaço disponível para a aldeia crescer. O objectivo deste artigo é perceber de que forma todos estes factores influenciam as chaves do território.

Apoio social, factores de risco e competências parentais percebidas em famílias multiproblemáticas no concelho de Silves

A família é caracterizada como o espaço de vivência de relações afetivas profundas: a filiação, a fraternidade, o amor, a sexualidade, numa trama de emoções e afetos positivos e negativos que, na sua elaboração, vão dando corpo ao sentimento de sermos quem somos e de pertencermos àquela e não a outra qualquer família. No contexto das Famílias “Multiproblemáticas” o principal desafio com que os técnicos se deparam é a relação que se estabelece entre profissionais e estas famílias, que enquadrados no modelo Ecossistémico, conceptualizou-se o desenvolvimento dos guiões de avaliação do profissional que implicam uma interrelação recursiva dos contextos dos quais faz parte. O presente trabalho pretende compreender as implicações de variáveis pessoais (experiência parental, bem-estar psicológico, satisfação com a vida familiar, satisfação com o apoio institucional entre outras). Concluiu-se que a família, desempenha um papel preponderante na eficácia das competências parentais. Assim, sugere-se o desenvolvimento de programas de intervenção junto destes familiares de forma a prevenir e minimizar os fatores de risco.

Factores determinantes de inovação nas pequenas empresas : uma aplicação ao sector agro-alimentar em Portugal

Este trabalho desenvolve instrumentos para pesquisar, ao nível regional, sinais determinantes de inovação em pequenas empresas localizadas em zonas desfavorecidas da União Europeia. Foram criados indicadores de performance inovadora para diagnosticar factores internos e externos determinantes da inovação em empresas portuguesas do Ribatejo Oeste e do Alentejo. Foi utilizada uma amostra aleatória de 52 empresas do sector agro-alimentar, com dimensão inferior a 50 trabalhadores, à qual foi aplicado um inquérito composto por 90 questões fechadas. Tais questões focaram grupos de determinantes possíveis de inovação, tais como: as características do empresário, a história e perfil da empresa, a força de trabalho e sua formação, os tipos de produtos e processos utilizados, as relações inter-empresariais e os apoios públicos fornecidos. Através das correlações de Spearman encontrámos relações de causa - efeito entre determinantes e performance inovadora.

Recreational shore fishing in southern Portugal: biological and socio-economic aspects and perspectives for management

Although overfishing is a concern for many fish stocks, it was for a long time only associated with commercial fishing exploitation, with less or no attention being given to the recreational fisheries. Recent research has shown however that the impact of recreational fishing on particular species can be considerable, and that the recreational harvest needs to be taken into account if fisheries are to be accurately assessed and effectively managed. In Portugal, the first recreational fishing regulations were only recently implemented. However, mirroring other European countries, regulations lacked scientific support, and specific knowledge of the activity was limited to a few studies with limited coverage. This thesis aimed to characterize the biological and socioeconomic aspects of the recreational shore angling activity in southern Portugal, to investigate whether the regulations in place were adequate and effective, and to provide recommendations for improved management and conservation of the inshore fisheries resources. A combined aerial-roving survey was conducted to gather data on fishing effort, catch, fishing trips and socioeconomic aspects (including anglers’ perceptions of regulations) of the recreational angling activity. The analysis of anglers’ catches suggested that compliance with daily bag limits was high, with less than 0.5% of creels exceeding the 10 kg angler-1 day-1 bag limit. Overall, 11.5% of the retained fishes were undersized, but non-compliance with minimum size limits was found to be high for some species (e.g. seabass, 73% undersized). In terms of the impact of recreational shore angling, the total estimated catches corresponded to less than 1% of the commercial landings for the same period (shared species). However, shore angling catches for white sea bream (Diplodus sargus) were found to be considerable, corresponding to 65% of the commercial landings (39.4% of total catch). In terms of anglers’ perceptions about the recreational fishing regulations in Portugal, the present study has shown that the majority of anglers accepted the existence of some kind of SRF regulations, but in general there was a partial or total disagreement with the recreational fishing restrictions recently put in place. Most anglers perceived themselves as not being involved in the decision-making process and claimed that some restrictions lacked a meaningful rationale (e.g. prohibition of fishing from piers/jetties). Fishers’ awareness with regard to specific aspects of the restrictions (such as the rationale for minimum size limits) was found to be very limited. During the same period, catches from sport fishing competitions were examined to test for differences with the recreational activity in terms of catches, and evaluate long term trends in catch and mean size of fish. Catches of the sport fishing competitions were found to be different from those observed for recreational fishing, being dominated by different species (e.g. garfish, mullets), and suggesting different fishing strategies of the the two types of anglers. High percentages of undersized fish were observed to be captured (and retained) during the competitions (in particular seabass, with 100% undersized), probably as a result of a single allowable minimum size (AMS) of 15 cm for all species in use in competitions. Lastly, catch and release fishing experiments were carried out to assess post-release mortality of three recreationally important species: two banded sea bream Diplodus vulgaris; black sea bream Spondyliosoma cantharus; and gilthead sea bream Sparus aurata. Post-release mortalities were found to be low (0-12%). The main predictor of mortality for Sparus aurata was anatomical hooking location, with 63% of the fishes that died being deeply hooked. The results support the release of fish, either from mandatory (e.g. minimum landing sizes) or voluntary practices. In summary, this thesis has demonstrated that the impact of recreational fishing for particular species is significant and needs to be taken into account for more effective management and stock assessment purposes. It has also highlighted several management issues that should be addressed in order to promote more adequate regulations in the future and prevent noncompliance issues. A periodic monitoring of the recreational fishing activity including all fishing modes (i.e. spear fishing, boat, and shore angling) would also be beneficial to ensure a timely knowledge on the global recreational fishing activity and support future management actions.

Socio-economic characterization of olive groves in a region in the south of Portugal

Serpa and Moura region, in the South of Portugal, have important agricultural potential as well as important agricultural resources that can and should be used and developed, in spite of economic and social depression signs reinforced by demographic difficulties that can lead to desertification in some areas. The main farms' Technical-Economic Orientation (TEO) is olives production, to produce olive oil, since this region has excellent conditions for the activity development. Some mobilizations traditionally made in olive groves lead to soil erosion and make the farm vehicles mobility much more difficult, namely those used in cultural operations. The maintenance of a soil cover in the olive grove space between lines is good, both because it favours the vehicles mobility, it promotes the rain water infiltration and, last but not the least, the soil airing. The objective of this work has been to make a socio-economic characterization of a zone of Serpa and Moura Councils in which a project of soil covers under olive trees is being developed. At the same time cultural accounts were made for the different situations under the study - irrigated olive grove with spontaneous vegetation in the space between lines, irrigated olive grove with seeded vegetation in the space between lines, irrigated olive grove with herbicide application in the space between lines, dry olive grove with spontaneous vegetation in the space between lines, dry olive grove with seeded vegetation in the space between lines and dry olive grove with herbicide application in the space between lines. The survey shows farmers in this area are younger then usual, although they don't have a high level of formal education, general or specific in agriculture. Farm areas are usually high, which can be determinant for the proposed technology adoption. Installation and operation costs for the olive grove are higher on the irrigated olive grove, but of course expected productions are also higher. For this production technology profits coming from olives production are higher then the operation costs. However, in the dry olive grove technology costs are always higher then the profits, being profitability only due to subsidies. The importance of soil cover maintenance, in this region, beside the benefits in what concerns erosion, infiltration and soil airing, is also due to its capacity to minimize the risk farmer's face.
