Nature and landscape sustainability in Portuguese rural areas: Which role for farming external benefits valorisation?

Traditional farming systems are declining rapidly in Portugal. These labour intensive and low productivity systems are incompatible with depopulation and ageing of rural areas. This lack of socio-economic sustainability endangers nature and landscape conservation. Agri-environmental measures, applied in European Union since 1994, can be seen as potential answer to that problem in the Portuguese case. But to be effective, these measures need to be part of an integrated strategy directed to mitigate depopulation. The NGOs and the official organisations related to nature and landscape conservation are aware of that and acknowledge it in the National Strategy for Nature and Biodiversity Conservation. This decline in the farming external benefits supply happens simultaneously with the increasing of its demand. General public, of all ages and socio-economic strata, wants rural nature and landscape conservation for use and nonuse purposes. Contingent Valuation studies conducted in the North of Portugal (Santos, 1997; Madureira, 2001) show a positive willingness to pay of visitors and general public to assure traditional agrarian landscape conservation. To preserve the rural cultural heritage is the main reason presented by the public to stand for landscape maintenance. Official data on land use and demographic trends, data on touristic demand for rural areas and empirical evidence on public preferences for rural nature and landscape attributes are used to witness these different directions in supply and demand for farming external benefits. A closer look to this divergence is taken for the case of Trás-os-Montes e Alto Douro. This Region contains various typical landscapes where farmer’s action shaped nature in a singular way. This feature attracts many tourists and visitants, which number is expected to grow, specially for Douro vineyards classified as Humanity Patrimony. But all of these landscapes are, to a more or less extent, risking being abandon or restructured to allow mechanisation. Afforestation it is also becoming an alternative pattern in soil occupation at the Region. Thus, this Region exemplifies very well the social and political choices that come up in the context presented in this communication: (1) Which landscapes to preserve? How much of it? And (2) How to do it? Use Beneficiary Pays Principle or Provider Gets based mechanisms? The first questions are mainly social issues, making evident the importance of getting information on public preferences for related political decisions. The second group asks for political choices, where the main challenge is to define and implement solutions capable of tuning in societal choices with local population and economic agents aspirations and resources. Without these solutions traditional landscape will disappear. Some face that as inevitability. But should it be so? The general public seems to disagree with that. And increasing touristic demand indicates opportunities for local development through farming external benefits valorisation. Bringing evidence and discussion on these questions is the main purpose of this communication.

MULTIFUNCTIONAL AGRICULTURE AS AN INNOVATION PATH FOR RURAL AREAS

The main purpose of this paper is to discuss the potential of MFA model to enhance innovation in rural areas build on the analysis of information from a database of best practices on innovation in EU rural areas collected by the RAPIDO project1. The analysis shows innovation to be strongly related to multiple-activity. This suggests the synergies between functions and land-uses to overlap the competition for resources between activities and that MFA shows a promising approach to enhance innovation in rural areas.Innovation, Multifunctionality, Rural areas, Sustainability, Agribusiness, Community/Rural/Urban Development,

Helium and neon isotopes in São Miguel island basalts, Azores Archipelago: New constraints on the “low 3He” hotspot origin

Lavas from the São Miguel Island, Azores Archipelago, have peculiar isotopic compositions, including radiogenic lead and strontium and un-radiogenic neodymium. The peculiar isotopic trend of São Miguel is evident in the lead-lead diagram where both 207Pb/204Pb and 208Pb/204Pb ratios are high for a given 206Pb/204Pb ratio compared to other oceanic island basalts. This signature is unique among OIBs and is particularly evident in the Nordeste area, the oldest part of São Miguel island (≥1 Ma). Only a few olivine samples from the Nordeste volcanic complex have been analyzed for helium. They show radiogenic helium signatures with 4He/3He up to 174,000 (R/Ra ~4) [Moreira et al., Helium and lead isotope geochemistry in the Azores archipelago, Earth Planet. Sci. Lett. 169: 189–205, 1999]. However, because the Nordeste volcano has an age between 1 and 4 Ma and because these samples have low helium concentrations, these radiogenic helium isotopic ratios must be considered with caution as they can also reflect post eruptive radiogenic production. In this paper we present a detailed study of the helium and neon isotopic ratios obtained from 17 Nordeste samples in order to better constrain the helium isotopic signature of the São Miguel mantle source. By coupling helium and the other isotopic systems, we propose that the São Miguel source contains non-degassed material, enriched in U and Th, that was stored in the mantle for the last ~3 Ga. As suggested by Elliot et al. [Elliott et al., The origin of enriched mantle beneath São Miguel, Azores, Geochim. Cosmochim. Acta 71: 219–240, 2007], underplated magma intruded into oceanic lithosphere and subducted ~3 Ga ago is a possible explanation for the peculiar São Miguel source isotopic signatures

Hybrid Prototypes to Assist Modeling Automotive Seats

The development of new modular seats is an important issue in the automotive industry. However, is very time consuming and costly. Virtual models and hybrid prototypes could accelerate the car seats development process. The hybrid prototypes are mainly manufactured by rapid prototyping with multi materials. The objective of this paper is to establish a methodology to develop innovative lightweight multi-functional, modular car seats to be used in Multi-Purpose Vehicles (MPV), by means of FEA simulation and rapid prototyping additive/subtractive technologies utilizing multi materials. A case study is presented to validate the developed methodology. The manufactured hybrid prototype’s reproduces the main functionalities of the MPV modular seat, namely its three key positions: normal, stored and table.Mechanical Engineerin

SEC Regulation Fair Disclosure, Information, and the Cost of Capital

We empirically investigate the effects of the adoption of Regulation Fair Disclosure ( Reg FD') by the U.S. Securities and Exchange Commission in October 2000. This rule was intended to stop the practice of selective disclosure,' in which companies give material information only to a few analysts and institutional investors prior to disclosing it publicly. We find that the adoption of Reg FD caused a significant reallocation of information-producing resources, resulting in a welfare loss for small firms, which now face a higher cost of capital. The loss of the selective disclosure' channel for information flows could not be compensated for via other information transmission channels. This effect was more pronounced for firms communicating complex information and, consistent with the investor recognition hypothesis, for those losing analyst coverage. Moreover, we find no significant relationship of the different responses with litigation risks and agency costs. Our results suggest that Reg FD had unintended consequences and that information' in financial markets may be more complicated than current finance theory admits.
