Assessing the societal benefits of river restoration using the ecosystem services approach

This paper is a contribution from the EU seventh framework funded research project REFORM (Grant Agreement 282656).The success of river restoration was estimated using the ecosystem services approach. In eight pairs of restored–unrestored reaches and floodplains across Europe, we quantified provisioning (agricultural products, wood, reed for thatching, infiltrated drinking water), regulating (flooding and drainage, nutrient retention, carbon sequestration) and cultural (recreational hunting and fishing, kayaking, biodiversity conservation, appreciation of scenic landscapes) services for separate habitats within each reach, and summed these to annual economic value normalized per reach area. We used locally available data and literature, did surveys among inhabitants and visitors, and used a range of economic methods (market value, shadow price, replacement cost, avoided damage, willingness-to-pay survey, choice experiment) to provide final monetary service estimates. Total ecosystem service value was significantly increased in the restored reaches (difference 1400 ± 600 € ha−1 year−1; 2500 − 1100, p = 0.03, paired t test). Removal of one extreme case did not affect this outcome. We analysed the relation between services delivered and with floodplain and catchment characteristics after reducing these 23 variables to four principal components explaining 80% of the variance. Cultural and regulating services correlated positively with human population density, cattle density and agricultural N surplus in the catchment, but not with the fraction of arable land or forest, floodplain slope, mean river discharge or GDP. Our interpretation is that landscape appreciation and flood risk alleviation are a function of human population density, but not wealth, in areas where dairy farming is the prime form of agriculture.PostprintPeer reviewe

New high performance hybrid composites with dyneema® fiber

The light weight and high strength of carbon fiber reinforced composites has resulted in it being widely adopted in many demanding applications such as in aerospace, automotive and sporting equipment. However, it is generally known that the brittle failure mechanism of these materials limits where and how it can be used. By combining carbon fiber together with Dyneema®, which is respected as the premium brand for high modulus lightweight fiber made from Ultra-High Molecular Weight Polyethylene (UHMWPE), it is possible to significantly improve the impact performance and ductility of the resultant hybrid composite. This paper demonstrates how it is possible to use Dyneema® fiber, specifically SK99 together with carbon fiber to produce a hybrid composite containing carbon with Dyneema® that possesses both light weight, structural and significantly improved impact performance

The Care Farming Sector in The Netherlands: A Reflection on Its Developments and Promising Innovations

This paper describes the development of care farming in the Netherlands, one of the pioneering countries in this sector, where care farming has developed into a very diverse sector, with some farmers focussing primarily on agricultural production and others more specifically on providing care services. Care farms are increasingly open to a diversity of participants. The sector has become professionalised with the establishment of strong regional organisations and a steady growth increase in revenues, providing employment opportunities and boosting the economy of rural areas. In this paper, we highlight two promising innovations in care farming: education for school dropouts and the establishment of social farming activities in cities. These innovations face the challenge of connecting not only the agricultural and care sectors, but also the educational sector and the urban context. Initiators face a number of challenges, like trying to embed their activities in the educational sector, a mismatch in regulations and a lack of legitimacy in the case of education on care farms, as well as problems gaining access to land and a lack of recognition in the case of social farming in urban areas. However, the prospects are promising in both cases, because they match the changing demands in Dutch society and are able to integrate social, ecological and economic benefits. View Full-Tex
