Urban-rural connections and development perspectives in Portugal

Portugal is characterized by a significant asymmetry in the population distribution/density and economic activity as well as in social and cultural dynamics. This means very diverse landscapes, differences in regional development, sustainability and quality of life, mainly between urban and rural areas. A consequence coherent with the contemporary dynamics: urbanization of many rural areas that loose their productive-agricultural identity and, simultaneously, the reintegration in urban areas of spaces and activities with more rural characteristics. In this process of increasing complexity of organization of the landscape is essential to restore the continuum naturale (between urban and rural areas) allowing closer links to both ways of life. A strategy supported in the landscape, which plays important functions for public interest, in the cultural, social, ecological and environmental fields. At the same time, constitutes an important resource for economic activity, as underlined in the European Landscape Convention. Based on this assumption, and using a multi-method approach, the study aims to analyse a) the links between urban and rural areas in Portugal and b) the reasons why these territories are chosen by individuals as places of work and mobility, residence or evasion, culture and leisure, tranquillity or excitement – meaning overall well-being. Primary information was obtained by a questionnaire survey applied to a convenience sample of the Portuguese population. Secondary data and information will be collected on the official Portuguese Statistics (INE and PORDATA). Understanding the urban-rural links is essential to support policy measures, take advantage from the global changes and challenge many of the existing myths.

Papel das medidas agro-ambientais na gestão da paisagem rural no concelho de Marvão no PNSSM

As paisagens rurais portuguesas construídas e mantidas ao longo dos tempos por sistemas agrícolas tradicionais, estão hoje ameaçadas por motivos tão diversos como o envelhecimento da população, o abandono rural, a intensificação, a homogeneização dos sistemas de produção e a perda de competitividade. Mas apesar destes problemas, estas paisagens agrícolas, suportam ainda várias funções não produtivas, nomeadamente, constituem, um importante suporte de biodiversidade, pelo que a sua manutenção é importante para a conservação destes habitats e espécies. Eventualmente novas formas de gestão destas paisagens devem ser criadas, nomeadamente com base na combinação de várias funções numa perspectiva de multifuncionalidade, através de uma adaptação e integração de políticas públicas. Estando actualmente em discussão o novo programa de Desenvolvimento Rural e a definição das futuras Medidas Agro-Ambientais, e a gestão e o financiamento da Rede Natura 2000, estamos portanto num momento crítico para decisões futuras, que terão forçosamente que interligar, a agricultura, o ambiente e desenvolvimento das zonas rurais portuguesas. Com o intuito de melhor compreender estas problemáticas, em particular, as transformações em curso na paisagem rural, o papel das Medidas Agro-Ambientais e apresentar possíveis soluções, foi efectuado este estudo de caso no concelho de Marvão, concelho típico das áreas marginais agrícolas do interior sul de Portugal. ABSTRACT; The Portuguese rural landscapes built up and kept throughout the times by traditional agricultural systems, are today threatened by so diverse reasons as the ageing of the population, the agricultural abandonment, the intensification, the homogenization of the production systems and the loss of competitiveness. But despite these problems. These agricultural landscapes still support a multitude of non-commodity functions, and particularly they still constitute an important support of biodiversity and thus their maintenance is important for the conservation of these habitats and species. Probably new management forms must be created based on the combination of various functions and the adaptation and integration of public policies. Being currently in discussion the new program of Rural Development and the definition of the future Agri-Environmental Measures, and the management and the financing of the Natura 2000 Network, we are therefore at a critical moment for future decisions that will forcibly have to establish connections, between the agriculture, the environment and the development of the portuguese agricultural areas. With the intention of better understanding these problems and questions, , the transformations taking place in Portuguese peripheric rural areas, and in particular role of the Agri-Environmental Measures, and also for presenting possible solutions, a case study was analyzed in municipality of Marvão, characteristic of the agricultural marginal areas of the interior Southern Portugal.

Understanding significant precipitation in Madeira island using high-resolution numerical simulations of real cases

In order to advance the knowledge about precipitation development over Madeira island, four rainfall patterns are investigated based on high-resolution numerical simulations performed with the MESO-NH model. The main environmental conditions during these precipitation periods are examined, and important factors leading to significant accumulated precipitation in Madeira are shown. We found that the combination of orographic effect and atmospheric conditions is essential for the establishment of each situation. Under a moist and conditionally unstable atmosphere, convection over the island is triggered, and its location was determined mainly by variations of the ambient flow, which was also associated with different moist Froude numbers. Interestingly, our results showed some similarities with situations discussed in idealized studies. However, the real variations of the atmospheric configuration confirm the complexity of significant precipitation development in mountainous regions. In addition, precipitating systems initially formed over the ocean were simulated reaching the island. The four periods were characterised by different time durations, and the local terrain interacting with the mesoscale circulation was decisive in producing a large part of the precipitation, which concentrated in distinct regions of the island induced by the airflow dynamic.

Occurrence of the pinewood nematode, Bursaphelenchus xylophilus in Portugal and perspectives of the disease spread in Europe.

In 1999, the pinewood nematode (PWN) , Bursaphelenchus xylophilus was found and identified for the first time in Portugal and in Europe. Following detection, Portuguese authorities initiated the implementation of eradication measures during 1999 and 2000, following an alert provided to European Community officials; as a result, the nematode was confirmed to be confined in the Setúbal region, near Lisbon. A task force from the follow-up group (GANP) created by the Secretary of State for the Rural Development established a national eradication programme (PROLUNP) to (1) Contain PWN within the initial geographic limits; (2) Implement eradication measures; and (3) Monitor PWN at a national level. Research is presently being conducted both at universities as well as research institutes, focusing on the characterization ofBursaphelenchus species associated with maritime pine, as well as on the insect vector, Monochamus galloprovincialis. Recent reports indicate that the nematode may be present in Siberia (Russia), which would present a threat to Eastern European forestry. Efforts are presently being developed by several European countries to establish a research consortium to detect and study the possible presence of PWN, for a new PRAs. A recent workshop held in Portugal, in 2001, has been an oportunity for sharing experiences and techniques on detection and control. There is clearly a greater awareness of this issue in Europe.

O papel da agricultura de conservação na luta contra a erosão do solo em particular em Angola

A agricultura de conservação, conseguindo reduzir as perdas de solo por erosão e aumentando o seu teor em matéria orgânica, permite aos agricultores produzirem mais alimentos com menos trabalho. Oferece-lhes uma possibilidade de melhorar a sua qualidade de vida. Várias abordagens sobre agricultura de conservação do solo, incluindo rotação e consorciação de culturas, são componentes deste sistema aplicável a diferentes níveis. A sementeira direta e o menor distúrbio de solo, são princípios primordiais da conservação do solo, fornecem benefícios direitos para a agricultura e o meio ambiente, questões da maior relevância para a agricultura Angolana, apesar da pouca importância que atualmente lhes é dedicada. Logo, é preciso uma conversão e transição de tecnologias e técnicas para implementar a agricultura de conservação e o controle da erosão dos solos no país. As técnicas de conservação utilizadas pelos pequenos e grandes produtores, embora sejam bem-intencionadas, não oferecem a proteção contra a erosão do solo e a conservação da água. Tanto as entidades políticas, como o Programa de Acão do Ministério da Agricultura e do Desenvolvimento Rural (MINADER) e os agricultores angolanos devem entender a importância da agricultura de conservação para a segurança alimentar e dar continuidade para as gerações futuras. Não basta a reformulação e consolidação dos objetivos traçados no período de 2009 a 2013, sem que haja a aplicação prática. Portanto, para sair do atual conceito oficial de agricultura tradicional/convencional e optar para agricultura capaz de responder às necessidades de Angola é necessário seguir modelos semelhantes aos desenvolvidos por países tropicais de condições naturais semelhantes às de Angola; The role of conservation agriculture in the fight against soil erosion particularly in Angola ABSTRACT: Conservation agriculture, managed to reduce soil losses by erosion and to increase its content of organic matter, allow farmers to produce more food with less work. It offers them a chance to improve their quality of life. Several approaches to soil conservation agriculture, including rotation and intercropping, are components of this system applicable to different levels. Direct sowing and less soil disturbance, are key principles of soil conservation providiy benefits for agriculture and the environment, issues of great importance for the Angolan agriculture, in spite of the little importance that is currently dedicated to them. Therefore, we need a conversion and transition technologies and techniques to implement conservation agriculture and soil erosion control in the country. Conservation techniques used by small and large producers, although well-intentioned, do not offer protection against soil erosion and water conservation. Both political entities, such as the Program of Action of the Ministry of Agriculture and Rural Development (MINADER) and Angolan farmers should understand the importance of conservation agriculture for food security and continuity for future generations. Not just the redesign and consolidation of the objectives outlined in the period 2009 to 2013, without practical application. Therefore, to exit the current official concept of traditional / conventional farming and opt for agriculture able to meet the needs of Angola is necessary to follow models similar to those developed by tropical countries of natural conditions similar to Angola.

How can the land managers and his multi-stakeholder network at the farm level influence the multifunctional transitions pathways?

The changing role of agriculture is at the core of transition pathways in many rural areas. Productivism, post-productivism and multifunctionality have been targeted towards a possible conceptualization of the transition happening in rural areas. The factors of change, including productivist and post-productivist trends, are combined in various ways and have gone in quite diverse directions and intensities, in individual regions and localities. Even, in the same holding, productivist and post-productivist strategies can co-exist spatially, temporally, structurally, leading to a higher complexity in changing patterns. In south Portugal extensive landscapes, dominated by traditionally managed agro-forestry systems under a fuzzy land use pattern, multifunctionality at the farm level is indeed conducted by different stakeholders whose interests may or not converge: a multifunctional land management may indeed incorporate post-productivist and productivist agents. These stakeholders act under different levels of ownership, management and use, reflecting a particular land management dynamic, in which different interests may exist, from commercial production to a variety of other functions (hunting, bee-keeping, subsistence farming, etc.), influencing management at the farm level and its supposed transition trajectory. This multistakeholder dynamic is composed by the main land-manager (the one who takes the main decisions), sub land-managers (land-managers under the rules of the main land-manager), workers and users (locals or outsiders), whose interest and action within the holding may vary differently according to future (policy, market, etc.) trends, and therefore reflect more or less resilient systems. The goal of the proposed presentation is to describe the multi-stakeholder relations at the farm level, its spatial expression and the factors influencing the land management system resilience in face of the transition trends in place.
