In recognition of these efforts it was elected European Green Capital in 2010 by the European Union. Among the numerous actions undertaken is the development of the green belt, over 120km of cycle paths, plans for the reduction of noise and light pollution, and many others that can be seen in Vitoria-Gasteiz Green Capital. As a further activity, the town hall, through the service of public space and natural environment, is developing an intervention with a view to incorporating technosols on vacant plots in the city in the future. The project, which started a few months ago,...

It developed in opposition to Descartes' Mechanism which left out any explanation of what life was and how it worked.

When in 1828, Friedrich Wohler, the rather confused-looking gentleman in the photograph, manages to synthesize urea, an organic substance from inorganic components, vitalism gives way to a new science, known as organic chemistry, which studies carbon and its relationships with other elements. What does this have to do with compost and humus? They are both formed of carbon and nitrogen, as well as other elements and micro-organisms, and are governed by the laws of organic chemistry. At EDAFOTEC we always say that...

Today in Europe and other countries the crisis has arrived before the completion of numerous construction sites, there are also other sites that are simply obsolete such as abandoned warehouses or factories. In many cases there is a certainty that they will never be finished or have any productive use, this is a process of decline in some cities that are seeing a drop in population and activity in recent years and where land supply exceeds demand, taking into account also the projection of the future needs of such cities. This is considered a problem mainly in the countries of Eastern Europe, and even in Ireland; the so-called bad bank has already started to demolish housing developments over the last few years in County Longford, as published in The Guardian. In Spain the wrecking ball also threatens ghost buildings. Spain has 800,000 unsold homes and experts...
