Extensive livestock systems and biodiversity: the case of Islay

2004 •

Bastiaan Brak

The relationship between extensive livestock systems and biodiversity has been examined in a case study on the Island of Islay (UK). As an introduction literature and relevant policy regulations have been reviewed. Farmers have been interviewed on agricultural, ecological and socio-economic aspects of extensive livestock farming. Requirements of typical bird species have been matched with land-use, farming practices and consequent habitat diversity. Variation within and between fields appears to be an important condition for typical bird species. Vegetation has been described by means of quadrate sampling in five different grazing situations. Occurrence of typical species of wet acid grass- and moorland appears to be linked to grazing with low livestock density. Analysis results show that such typical species may be lost due to either intensification or abandonment of grazing on rough grazing fields. Recent agricultural policy measures appear to have been effective in impeding the i...

Mulberry (Morus spp.) as a fodder source to overcome climate change

Rosa Mosquera-Losada

Agroforestry practices are excellent tools to mitigate and adapt to climate change. Climate change will increase the summer drought period in the south of Europe. Feed shortage can be overcome by the use of tree leaves and soft branches to feed to livestock. The leaves of mulberry are known to be of high quality (protein content and digestibility) for animals. This experiment aims to determine productivity and fodder quality of four Morus spp. clones: M. alba criolla; M. alba tigrenda, M. alba illaverde and M. nigra. A randomized block design (3 blocks × clone) was set up in the northwest Spain (Lugo, Galicia) in 2015. One year after establishment, field measurements were recorded (survival, tree height, base and crown diameters) and plant subsamples were taken to determine production and protein content. The four Morus spp. clones showed a high survival rate (>90%). M. alba illaverde produced the highest yields and growth compared with other mulberry clones. Despite differences in production, all four Morus spp. clones have shown high leaf protein content (100-180 g kg‑1) with no significant differences among them. Thus, our initial study showed promising results on the use of mulberry leaves as animal fodder in temperate agroforestry systems.

Grassland-based products: quality and authentication

Rosa Mosquera-Losada

There is increased consumer demand for food products with a perceived positive image. Product quality can be assessed in terms of food safety, nutritional composition, technological and sensory characteristics and ethics. In order to summarise the current knowledge linking quality traits and management practices, a literature review was performed in relation to seven types of management practice: four concerning animal feeding, one concerning breeds and two concerning ethical aspects of the production, and information is presented as seven tables. Literature on use of authentication and traceability for marketed grassland-based products is summarised in a further five tables. Scientific evidence of the differentiation of grassland-based products is currently consolidating, but some practices lead to uncertain results and deserve further research. Authentication is possible but is used to a relatively small extent because of high costs or the lack of analytical techniques suitable for routine use. Marketing appears to be successful without authentication, but this may lead to product counterfeiting. Research and development should be targeted to find viable low-cost solutions to introduce authentication practices to safeguard the added value of grassland-based products and ensure fair remuneration for producers.

Maize yield in silvoarable systems established under Prunus avium L. in Galicia (NW Spain)

Rosa Mosquera-Losada, Nuria Ferreiro-Domínguez

In recent years, in Galicia (NW Spain) the forest area has increased gradually and therefore the availability of agricultural area has decreased. This factor could favour the establishment of silvoarable systems in this region with crops such as maize, because in Galicia maize is the main forage crop to overcome periods of shortage in summer and winter. In silvoarable systems, the production of the crops depends, among other aspects, on tree species and its density when planted. The aim of this study, in Galicia (NW Spain), was to evaluate the yield of maize at different distances from the trees (1.5, 3 and 6 m) in a silvoarable system under Prunus avium L., compared with an exclusively agronomic system. The results obtained showed that maize production increased significantly with the distance from the trees and that maize production combined with trees was lower than the production found in the plots without trees, because of a reduction in maize yield and also due to the surface occupied by trees.

Productivity of silvopastoral systems under Pinus radiata D. Don estimated with the Yield-SAFE model

Rosa Mosquera-Losada, Nuria Ferreiro-Domínguez

The Yield-SAFE is a biophysical model to predict the long-term production according to light and water availability in exclusively agricultural and forest systems and also in agroforestry systems. The productivity estimated with the Yield-SAFE model can be used to determine the Land Equivalent Ratio (LER). The LER allows comparison of the productivity of an agroforestry system with the productivity of a monoculture system. The objective of this study was to determine the productivity of exclusively forest and agricultural systems and a silvopastoral system established with Pinus radiata D. Don in Galicia (NW Spain) through the Yield-SAFE model to calculate the LER. The results showed that the LER simulated by the Yield-SAFE model was 1.41. This value indicates that the hypothetical silvopastoral system of this experiment produced 41% more than the exclusively forest and agricultural systems, probably due to the diversified production of the silvopastoral systems. Therefore the establishment of silvopastoral systems could be promoted in Europe due to its high productivity compared with the exclusively forest and agricultural systems, which is increased by the non-market products that agroforestry systems support.
