    In the framework of the National Proyect: "Tipification, Cartography and Evaluation of Spanish Pastures" (INIA 00T00-037-C17-08) and Junta de Comunidades de Castilla-La Mancha, 2001-2004), promoted by the Spanish Society of Pastures Studies, "dehesas" areas are obtained depending on the uses of different cartographic sources. A comparative analyze has been carried out in Toledo province (Spain). Data used were obtained from the Spanish Forestry Map, the CORINE-LAND COVER 2000 proyect and Cadastral information.

    Acid sulfated soils are characterized by high amounts of iron and sulfur, which in presence of air are oxidized and form sulfuric horizons extremely acidic, generating environmental changes ranging from water pollution to problems associated with fertility and crop production, among others. This research was conducted in order to identify suitable plant species to control the acidity of these soils in the town of Paipa, Boyacá, Colombia. A completely randomized experimental design with 6 treatments and 3 replications was implemented in potting shed; there, the response of Beta vulgaris L.

    La dehesa es un ecosistema agroforestal único que aúna un óptimo rendimiento económico con una menor incidencia en el medio. En la Península Ibérica hay unas 500.000 hectáreas de dehesas concentradas en Andalucía, Castilla y León, Extremadura, Castilla La Mancha y Madrid. Las razas autóctonas son las que, por su rusticidad y adaptación, mejor aprovechan y conservan la dehesa.

    The major citrus production of the world are located between 20-40 degrees north and south latitude. In these conditions the mandarins get the best internal and external qualities.‘Arrayana’ is the main mandarin cultivated in Colombia tropical lowlands (around 04° N). This variety is characterized by a high concentration of the harvest in december and january because it has only one principal bloom in the year (two weeks after onset of rainy season); and an average external quality that prevents it from being highly competitive.

    Animal genetic resources ex situ conservation is an essential and complementary tool to in situ conservation. It is one of the main procedures for population recovery. The aim of this study was to calculate and to break down the cost, determining criopreserved seminal doses annual maintenance expenses by species. During the study, the costs of two maintenance methods, on one hand kept under self-maintenance and on the other hand by means of hiring an outside maintenance service, were compared for the following species: cattle, goats, sheep, pigs and equines.

    Spain, Europe

    The process of agricultural abandonment has been taking place for the last decades all around Europe. This process has special effect on mountain livestock farming, as it is the case of that of Catalan Pyrenees, which is characterised by an extensive management of the herd between the alpine grasslands in summer and the hay meadow of the lower valleys in winter. The process of agricultural abandonment, apart from the obvious closing down of the exploitations, also implies a gradual decrease of the management intensity of the farming exploitation.

    Guatemala, Honduras, Central America

    The presence of trees in the farms is typically considered a good practice in water shed  management. Therefore, it was examined the voluntary adoption of land uses considered more compatible with the water ecosystem service (shade coffee and woodland) in the region of Trifinio (located in Honduras and Guatemala), where there is not given any incentives or payment for this environmental service. It was observed low adoption of these land uses on small farms.
