   The stabling of livestock farming implies changes in both local ecosystems (regeneration of forest stands via reduced grazing) and those located thousands of kilometers away (deforestation to produce grain for feeding livestock). Despite their importance, these externalities are poorly known. Here we evaluated how the intensification and confinement of livestock in Spain has affected forest surface changes there and in South America, the largest provider of soybeans for animal feed to the European Union.

   Discussions about climate change have repeatedly regarded livestock as responsible for a significant contribution of greenhouse gas emissions. However, proper management schemes for livestock production may contribute to a reduction in emissions and, at the same time, induce optimization of production systems and intensification of food production.

   Nine Latin American countries plan to use silvopastoral practices—incorporating trees into grazing lands—to mitigate climate change. However, the cumulative potential of scaling up silvopastoral systems at national levels is not well quantified. Here, we combined previously published tree cover data based on 250 m resolution MODIS satellite remote sensing imagery for 2000–2017 with ecofloristic zone carbon stock estimates to calculate historical and potential future tree biomass carbon storage in Colombian grasslands.

   résilience

   Livestock farming systems have an important role in the territorial systems of the Mediterranean, but in the last twenty years the sector has undergone serious changes with an important decrease in the number of farms. The purpose of this study is to show the contribution of a local food certification to the resilience of peri-urban livestock farming system and of its food supply chain at territorial level.

   A “Young Farmer Problem”? Opportunities and Constraints for Generational Renewal in Farm Management: An Example from Southern Europe

   Volume 8 Issue 4

   The existence of a “young farmer problem” in Europe has been recognized by scientists and policy-makers and is based on the widespread acknowledgement of the poor generational renewal rates in the farming sector and in particular in farmland management across the European Union. Despite existing support policy measures, young farmers (YF) face barriers which hamper the establishment and consolidation of their farming enterprises.

   La raza Castellana se halla distribuida por distintas áreas de la Comunidad de Castilla y León, si bien la mayor parte de su censo se encuentra en comarcas del oeste de la provincia de Zamora. Raza de doble actitud carnicera y lechera, su explotación se halla orientada mayoritariamente a la producción de carne, si bien los escasos rebaños inscritos en el libro genealógico se hallan dedicados a la producción lechera.

   After a previous description of pasture utilization in Sierra de Guara Natural Park, eight sheep farms were selected for a study of the relationships between farming systems and land use at the farm level. They were representative cases obtained from a previous typology based on criteria of technical management and pasture use. After a detailed description of the system, a SWOT analysis was carried out in order to identify the main factors involved in farm continuity and sustainability of land use.

   8 flocks of Ojinegra ewes (n=5634) were studied during a productive cycle (2007-2008) in Teruel (Spain), a low-mountain dry and harsh area. Ojinegra ewes belong to a local breed, of small-medium size, reared under a semi-extensive system of management. Throughout three seasons (autumn, winter and spring) weight and BCS of 5634 ewes at lambing and weaning were recorded and 5786 lambs were weighed fortnightly form birth to weaning. Season had a significant (p>0.01) effect on weight and BCS of ewes and on lambs average daily gain.

   A survey that gathered information about farm structure, grazing system, feeding and reproductive management was conducted in 181 farms. Parda de Montaña is the main breed regarding cows (92.4%), heifers (95,3%) and calves (84,1%). Bulls belong to Parda de Montaña (65%) breed but also Limusine, Charolaise and Blonde d'Aquitaine. Farms had an average size of 53.6 cows. Feeding depends largely on grazing in different forage resources, from June to October in high mountain ranges, in spring and autumn in natural meadows and forage crops.

    Surveys were conducted to 141 farmers registered in the FERPAM at Asturias (A), Cantabria (C) and Castilla and Leon (CL) regions, with the aim to know animal production system characteristics. Racial diversity was high (57.4% of the cows are "Parda de Montaña" (PM) and the 25.2% are cross with other breeds) and only 24.1% of farms have PM pure-breed animals. The average herd size was 32.1 cows in A, 35.3 in C and 64.6 in CL. The 95% of farms are located in mountain areas. The animals are kept indoors 3.7 months/year, as average. The average age of calves weaning was 5.8 months.
