Economical Issues Regarding the Implementation and Functioning of the Common Catalogue of Varieties of Agricultural Plant Species

2013

Abstract Economical constraints regarding the full implementation and functioning of the common catalogue on plant genetic resources for food and agriculture (PGEFA) are discussed in this paper based on the assessment of the current European Union regulatory framework. Based on this article's results new financial mechanisms should be developed at the national level for further responding to the European requirements including measures regarding the conservation varieties. This assessment is further supporting the need for developing and implementing new financial mechanisms in the support of the poor rural populations as well as for small farmers in harmony with commercial agriculture.

Effect of Cold Smoking and Natural Antioxidants on Quality Traits, Safety and Shelf Life of Farmed Meagre (Argyrosomus regius) Fillets, as a Strategy…

2021

Aquaculture has been playing a leading role over the years to satisfy the global growing demand for seafood. Moreover, innovative techniques are necessary to increase the competitiveness, sustainability and profitability of the seafood production chain, exploiting new species from the aquaculture, such as meagre (Argyrosomus regius), to develop value-added products and diversify their production. In the present work, the effectiveness of cold smoking combined with antioxidants (SA) compared to cold smoking alone (S) on meagre fillets, the quality and shelf life were investigated. Sensory, biochemical, physical–chemical and microbiological analyses were performed on the smoked fillets during…

Pesticide doses, landscape structure and their relative effects on farmland birds

2014

International audience; tAgricultural changes related to the intensification of farming practices and the simplification of land-scape elements often occur simultaneously. Their respective effects on biodiversity are thus difficult todisentangle and are poorly understood. This study assessed the relative contribution of each componentof agricultural intensification on taxonomic and functional bird communities.The bird communities studied were composed of 70 species, both farmland and non-farmland birds,found in 66 fields covering three main cereal departments of France. Herbicide dose was related to mea-surable negative effects on the Community Specialization Index (CSI). Overall, the propo…

Role of rock fragment cover on runoff generation and sediment yield in tilled vineyards

2017

Summary The soil in conventional Mediterranean vineyards is an active and non-sustainable source of sediment and water. Lack of vegetation cover, small soil organic matter content and intense ploughing result in large rates of erosion in a millennia-old tillage system. There is a need for soil conservation strategies that enable sustainability of wine and grape production; therefore, it is essential to measure the rates and to investigate the processes and factors of soil erosion. This study evaluated factors that can reduce soil losses in traditional Mediterranean vineyards. The investigation was carried out with 96 rainfall simulation experiments at the pedon scale (0.24 m2) to measure so…

The effect of mariculture facilities on biochemical features of suspended organic matter (southern Tyrrhenian, Mediterranean)

2006

Abstract A comparison of a Mediterranean aquaculture impacted area and control areas was made to assess the effect of fish farm waste discharge on the biochemical features of the water column. Trophic variables commonly used in marine ecology such as total suspended matter, suspended chlorophyll- a , biochemical features of particulate organic matter (proteins, lipids and carbohydrates) and biopolymeric carbon were chosen as the best descriptors of trophic conditions. An initial analysis of data from the impact area was carried out in order to test the effect of farm waste using a gradient of distances downstream from the fish farm cages (50 m, 300 m, 1000 m). The results were then compared…

Shrubland as a soil and water conservation agent in Mediterranean-type ecosystems

2015

John Thornes found that shrubland was a key factor in the control of soil erosion on Mediterranean hillsides. His research inspired many scientists to investigate the impact of shrubland changes and management in semi-arid ecosystems. An example of Professor Thornes’ scientific influence is the experiment carried out on the El Teularet–Sierra de Enguera experimental station since 2003 which showed erosion rates on a 30-year-old abandoned orchard with dense vegetation cover of Ulex parviflorus and Cistus albidus and a 20-year-old fire-affected maquia with Quercus coccifera, Pistacia lentiscus and Juniperus oxycedrus. The measurements demonstrated that the shrubs help create more stable soil …

Groundwater nitrate risk assessment using intrinsic vulnerability methods: A comparative study of environmental impact by intensive farming in the Me…

2015

Abstract Groundwater contamination by nitrate and other nutrients is a major problem throughout the world, often occurring as the result of anthropogenic activities, lack of management, and over-exploitation of groundwater resources. In the last few decades in the majority of the Italian regions, the nitrate concentrations in groundwater have dramatically increased, mainly as a consequence of the large-scale agricultural application of manure and fertilizers. This excessive use of chemicals and fertilizers increases the risk of surface and groundwater pollution from diffuse sources, which have an important impact on human health and the environment. Sicily is located in the central Mediterr…

<em>Changes in land use in watershed will affect peak discharge and degradation land. It is becoming an indicator of better or worse use of land in watershed area. This study aims to analysis land use change, to predict peak flows based on changes in land use and land use change scenarios in the Pami watershed. This study uses a number of primary data and secondary data. Primary data were obtained from observations of the condition of the land and soil sampling, which is then analyzed in the laboratory. Secondary data were obtained from literature and related agencies such as geographical map and thematic maps including land map, administrative area maps, land use maps in 1996-2015 an…

El secano mejorado y la agricultura aterrazada. Paisajes significativos con un gran valor socio-ambiental y didáctico

2019

En los últimos veinte años, en las denominadas sociedades postproductivistas se ha producido un redescubrimiento del paisaje asociado a su identificación como un elemento identitario y de calidad. En la provincia de Alicante, representativos resultan el denominado secano mejorado (aprovechamiento de turbias) característico de la comarca de l’Alacantí y los paisajes aterrazados (Montaña de Alicante). Los objetivos de esta investigación son: 1) Analizar la ordenación tradicional de los paisajes derivados del uso de turbias y los aterrazados; 2) Analizar las estrategias de adaptación al medio y cómo el proceso de abandono ha repercutido ambientalmente en el área de estudio; 3) Poner de manifie…
