Les principes de la permaculture On voit sou­vent la per­ma­cul­ture pré­sen­tée par des ap­pli­ca­tions concrètes au jar­din, ce qui peut don­ner l’impression que la per­ma­cul­ture n’est qu’une ac­cu­mu­la­tion de ‘tech­niques’ de jardinage : culture sur buttes pour ne pas labourerpaillage épais et sys­té­ma­tique pour que le sol ne soit ja­mais à nucom­pos­tage en sur­face pour perdre moins d’azote que dans un tas de compostjardin-forêt pour imi­ter l’écosystème-roi de nos contréeszones pour moins s’embêter quand il pleutjar­dins man­dala pour ré­duire l’espace ré­servé aux alléesspi­rales d’herbes aro­ma­tiques pour faire jolitrac­teur à poules pour désher­ber et fertiliserbais­sières (swales) pour pié­ger l’eau de ruis­sel­le­ment dans le paysagetours à patatesto­mates non-tailléesetc. Quoique in­té­res­santes et même sou­vent ef­fi­caces, ces tech­niques mises bout-à-bout ne font pas la per­ma­cul­ture.

Portal:Culture From Wikipedia, the free encyclopedia For a topical guide of this subject, see Outline of culture Culture generally refers to the patterns of human activity, and the symbolic structures that give such activities significance and importance. Cultures can be "understood as systems of symbols and meanings that even their creators contest, that lack fixed boundaries, that are constantly in flux, and that interact and compete with one another". Culture can be defined as all the ways of life: including arts, beliefs, and institutions of a population that are passed down from generation to generation. Today the Greeks call themselves Hellenes (Έλληνες), though they have been known by a number of different names throughout history. Purge cache The Society for Human Ecology

European super grid A conceptual plan of a European super grid linking renewable energy projects like DESERTEC & Medgrid across North Africa, the Middle East and Europe and could serve as the backbone for the hypothetical supersmart grid. The European super grid is a possible future super grid that would ultimately interconnect the various European countries and the regions around Europe's borders – including North Africa, Kazakhstan, and Turkey. – with a high-voltage direct current (HVDC) power grid.[1] It is envisaged that a European super grid would:[1] Proposed schemes[edit] The most comprehensive study has been carried out by Dr Gregor Czish, of Kassel University.[2][3] His study optimised a vast grid covering North Africa, Eastern Europe, Norway, and Iceland. His study ran a number of scenarios, wind, csp, nuclear etc., and the optimisation showed that all European power could largely come from wind energy, with releatively low amounts of combustion plant needed during universal low wind periods.

Environmental education Environmental education (EE) refers to organized efforts to teach about how natural environments function and, particularly, how human beings can manage their behavior and ecosystems in order to live sustainably. The term is often used to imply education within the school system, from primary to post-secondary. However, it is sometimes used more broadly to include all efforts to educate the public and other audiences, including print materials, websites, media campaigns, etc. Related disciplines include outdoor education and experiential education. Environmental education is a learning process that increases people's knowledge and awareness about the environment and associated challenges, develops the necessary skills and expertise to address the challenges, and fosters attitudes, motivations, and commitments to make informed decisions and take responsible action (UNESCO, Tbilisi Declaration, 1978).

Permaculture Bienvenue sur la page ressources Incredible Edible et la pratique de la Permaculture ! Pour une première découverte de la Permaculture, la reportage vidéo ci-dessus présente une bonne vision d’ensemble avec le témoignage d’Éric Escoffier qui est formateur professionnel. Ce petit clip donne un rapide tour d’horizon de cette technique douce de l’agriculture, encore assez récente en France, contrairement à l’Australie qui est très avancée dans cette pratique, ainsi que de nombreux pays anglo-saxons. Brin de paille est l’association française qui a pour mission de promouvoir la permaculture, de mettre en réseau les acteurs français qui la pratiquent ou souhaitent y parvenir en échangeant les expériences. Pour découvrir les programmes d’action de l’Université Populaire de Permaculture en France, le lien est ICI. Il existe un portail de ressources documentaires sur la permaculture pour les permaculteurs francophones, le lien est ICI. Site internet de Permaculture Blue Mountains, lien ICI.

Portal:Health and fitness Physical fitness is an attribute required for service in virtually all militaries. The notion of physical fitness is used in two close meanings. General fitness In its most general meaning, physical fitness is a general state of good physical health. A physically handicapped person's body may be physically fit (healthy), though its ability is likely to be less than optimum. Physical fitness is usually a result of regular physical activity and proper nutrition. Physical fitness can be divided into different areas, including: The government Physical Activity Guidelines for Americans say to aim for at least 2 hours and 30 minutes of aerobic activity that requires moderate effort each week. Task-oriented fitness A person may be said to be physically fit to perform a particular task with a reasonable efficiency, for example, fit for military service. Military-style In recent years, Military-style fitness training programs have become increasingly popular among civilians. Definition Cholesterol

Civic Ecology Lab, Cornell University Smart grid A smart grid is a modernized electrical grid that uses analog[1] or digital information and communications technology to gather and act on information - such as information about the behaviours of suppliers and consumers - in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity.[2] Electronic power conditioning and control of the production and distribution of electricity are important aspects of the smart grid. Smart grid policy is organized in Europe as Smart Grid European Technology Platform.[3] Policy in the United States is described in 42 U.S.C. ch. 152, subch. IX § 17381. Roll-out of smart grid technology also implies a fundamental re-engineering of the electricity services industry, although typical usage of the term is focused on the technical infrastructure.[4] Background[edit] Historical development of the electricity grid[edit] Modernization opportunities[edit] Definition of "smart grid"[edit]

Labour traditionnel en Allemagne, plus superficiel qu'au tracteur, plus lent, mais bien moins tassant et asphyxiant pour le sol profond labour traditionnel au Tibet Par extension, le terme « labour » désigne le champ labouré (par opposition à la partie non labourée, le « guéret »). Le terme vient de « labourer », du latin, laborare, travailler. C'est un doublet indirect de « labeur ». Depuis peu, on expérimente un labour très profond sur lequel les arbres semblent particulièrement bien pousser, avec aussi quelques expériences agricoles (culture sur sol inversé en rizière par exemple) Avantages[modifier | modifier le code] Inconvénients[modifier | modifier le code] Le labour présente cependant de graves inconvénients tels que : créer une « semelle de labour ». Avec les méthodes de labour actuelles, certains sols, sensibles à l'érosion, s’érodent d’un millimètre par an. Depuis un peu plus de dix ans, le labour est remis en cause. Schéma 1.
