La educación de adultos en zonas rurales en proceso de modernización : situación del debate en la República Federal de Alemania.

Está en fase de reorientación y cambio del espacio agrícola. En los últimos cincuenta años se ha desarrollado de forma rápida e imparable, ya poco después de 1945 fue identificado por la educación de adultos como un reto y problema. Pero, el espacio rural quedó rezado a un segundo plano, también para la educación de adultos. Los potenciales educativos y los recursos humanos latentes en él, debían ser encomendados a una labor educativa urbana. Para la mayoría e los científicos el espacio rural desempeñaba hasta hace pocos años un papel secundario o no desempeñaba papel alguno. Pero este enfoque urbano limitado a la educación de adultos ha ido cambiando a partir de los años ochenta sin que pueda hablarse en la actualidad de una època dorada de la educación de adultos en las zonas rurales, en los últimos años se ha cuestionado críticamente la propia posición. Se ha detectado las insuficiencias y se han hecho esfueszos para corregir las deficiencias, por lo menos en el modelo y de forma visible de cara a la colectividad política y elaborar perspectivas. Este cambio realista desde lo años ochenta de la educación de adultos en zonas rurales. Las orientaciones hacia la labor cultural y educaciones forjadoras de identidad y determinadas por lo geográfico-temporal y búsqueda de las raíces y tierra natal, es su lema. Y no los nuevos acercamientos cualitativos al espacio cultural pueden justificar que se constate un cambio hacia lo cotidiano. Así, actualmente se define la educación de adultos como un factor de desarrollo y localización.

El desenvolupament local en l'espai en xarxa: xarxes socials i milieu a l'àrea urbana de Manresa

The paper focuses on the question of local development and applies the local territorial systems model to the urban area of Manresa (Barcelona). The concept of local development is discussed first, as well as the change in place's position within the network derived from metropolitan expansion processes. The role of Manresa's social agents and its development policies are explained, to stress the relevance of the position of places in the network and, foremost, of the role and capability of local actors in putting into value theirs milieu's resources

Pea-barley intercrops use nitrogen sources 20-30% more efficiently than the sole crops

Field pea (Pisum sativum L.) and spring barley (Hordeum vulgare L) were intercropped and sole cropped to compare the effects of crop diversity on the use of nitrogen sources in European organic crop-ping systems. Across a wide range of growing condi-tions pea-barley intercropping showed that nitrogen sources were used from 17 to 31% more efficiently by the intercrop than by the sole crops. Intercropping technologies offers the opportunity for organic cropping systems to utilize N complementarity between component crops, without compromising total crop N yield levels

The 2003 CAP Reform: Accommodating WTO Pressures

In 2003, the EU agreed a major reform of the common agricultural policy (CAP). Its centrepiece was a new Single Payment Scheme (SPS). Policy concerns at the time involved the budget, EU enlargement to the East, the WTO negotiations, and a perception (articulated by Commissioner Fischler) that there should be a shift of budget funds from CAP's Pillar 1 (price and income support) to Pillar 2 (rural development). We outline these concerns, conclude that the WTO was the main driving force of the reforms, set out the key parameters of the new support scheme, and outline some thoughts on the durability of the reformed CAP in the face of continued internal and external pressures.

The keeping quality of LPS-activated milk in the western highlands of Cameroon

The potentials of applying the lactoperoxidase system (LPS) in extending the shelf life of raw milk at ambient temperatures was investigated in the western highlands of Cameroon. Raw milk was LPS-activated by adding various concentrations (ppm) of thiocyanate and peroxide and denoted as 0:0, 7:10 ppm, 10:10 ppm and 20:20 ppm. The keeping quality of the activated milk samples was assessed by the alcohol stability and clot-on-boiling tests, pH changes and titratable acidity. The milk in all the treatments remained fresh during the first 12 hours but the control was spoiled by the 15th hour. There was a continuous drop in pH values matched by a steady rise in titratable acidity. For all parameters measured, 20:20ppm was the last treatment to spoil, suggesting that the shelf life of milk increases with increasing concentrations of thiocyanate and peroxide. With small amounts of thiocyanate (20 ppm) and peroxide (20 ppm) the shelf life of raw milk can effectively be extended under Cameroonian conditions by approximately 9 hours without refrigeration. Thus LPS-activated milk can be stored for as long 21 hours, allowing sufficient time for its appropriate disposal.
