Integrating periurban agrarian ecosystem services into spatial planning to cope with urban pressure

According to Corine Land Cover databases, in Europe between 1990 and 2000,77% of new artificial surfaces were built on previous agrarian areas. Urban sprawl ¡s far from being under control, between 2000 and 2006 new artificial land has grown in larger proportion than the decade before. In Spain, like in most countries, the impact of urban sprawl during the last decades has been especially significant in periurban agrarian spaces: between 2000 and 2006, 73% of new artificial surfaces were built on previous agrarian areas. The indirect impact of this trend has been even more relevant, as the expectations of appreciation in the value of land after new urban developments reinforce the ongoing trend of abandonment of agricultural land. In Madrid between 1980 and 2000 the loss of agricultural land due to abandonment of exploitation was 2-fold that due to transformation into urban areas. By comparing four case studies: Valladolild, Montpellier.Florence and Den Haag, this paper explores if urban and territorial planning may contribute to reduce urban pressure on the hinterland. In spite of their diversity, these regions have in common a relative prosperity arising from their territorial endowments, though their landscapes are still under pressure. The three last ones have been working for years on mainstream concepts like multifunctional agriculture. The systematic comparison and the analysis of successful approaches provide some clues on how to reconsider urban planning in order to preserve agricultural land. The final remarks highlight the context in which public commitment, legal protection instruments and financial strategies may contribute to the goals of urban, peri-urban or regional planning about fostering agrarian ecosystem services

La sostenibilidad en la planificación territorial de escala regional en España: estudio de casos

En las dos últimas décadas, la expresión «desarrollo territorial sostenible» se ha incorporado con éxito en los documentos de ordenación del territorio, hasta convertirse en un principio rector principal. El objetivo de este artículo es analizar la incorporación de los principios de sostenibilidad en la planificación territorial española, valorando los resultados prácticos que ello ha significado. Se ha realizado un análisis de las leyes y planes de ordenación del territorio de escala regional, destacando en cuatro casos de estudio (País Vasco, Navarra, Andalucía y Comunidad Valenciana) por la relevancia que este principio rector ha cobrado en sus procesos de planificación territorial. Se ha completado la información con la realización de entrevistas a actores clave de la ordenación del territorio en esos espacios regionales. Los resultados muestran que, a pesar de las buenas intenciones que incluyen los textos de leyes y planes, por lo común, el proceso de integración de la sostenibilidad a la planificación territorial de escala regional es lento y sus efectos prácticos todavía son escasamente visibles.

Cincinnati, Ohio, 1925 (Raster Image)

This layer is a georeferenced raster image of the historic paper map entitled: Regional plan map of Cincinnati, Ohio, prepared by City Planning Commission, Technical Advisory Corporation Consulting Engineers. It was published by Technical Advisory Corp. in 1925. Scale 1:62,500. Covers also a portion of Northern Kentucky. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Ohio South State Plane NAD 1983 coordinate system (in Feet) (Fipszone 3402). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This is a typical topographic map portraying both natural and manmade features. It shows and names works of nature, such as mountains, valleys, lakes, rivers, vegetation, etc. It also identify the principal works of humans, such as roads, railroads, boundaries, transmission lines, major buildings, etc. Relief is shown with standard contour intervals of 20 feet. This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection as part of the Imaging the Urban Environment project. Maps selected for this project represent major urban areas and cities of the world, at various time periods. These maps typically portray both natural and manmade features at a large scale. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.
