Geometría y Arquitectura en las iglesias cortesanas de Madrid en el siglo XVIII

Con la llegada al trono español de Felipe V, una pléyade de arquitectos y artistas italianos y franceses fueron llamados a Madrid por la nueva dinastía borbónica para cambiar el gusto artístico de un país de cultura y costumbres ajenas. De las obras que estos arquitectos dejaron en España, nos hemos centrado en la arquitectura religiosa por ser más evidente esta influencia. Hemos analizado dos iglesias madrileñas: la de San Ignacio y la Basílica Pontificia de San Miguel (antes iglesia de los santos Justo y Pastor).

Urban agriculture in the new framework of green cities.

Urban Agriculture was a common practice in the old times. However after a period of low interest by urban population there is a movement of renaissance of urban agriculture especially in the new megalopolis. It is important to understand the role of UA in the new framework, and the interface of urban and rural agricultures, with their comparative advantages. Thus, we describe the impact of UA in several scenarios: political, socioeconomic and environmental. As a consequence several actions should be developed for improving the situation, with the stimulus to UA: urban planning, food value chain, appropriate technology, education and extension services, entertainment and leisure, selection of botanic varieties and agrochemical inputs, design and landscape and good farming practices. As a complement, there is an analysis of the Urban Greening Value Organization in our society. In the paper there is a description of the situation of urban agriculture in Spain (located mainly in roofs, walls, indoor and ground places) the existence of local regulations, barriers and opportunities in the new situation. Due to the social dimension of urban agriculture there are some comments about the role of the more significant stakeholders, and the goals and the structure of the neighbor communities.
