Seawater Greenhouse A seawater greenhouse is a greenhouse structure that enables the growth of crops in arid regions, using seawater and solar energy. The technique involves pumping seawater (or allowing it to gravitate if below sea level) to an arid location and then subjecting it to two processes: first, it is used to humidify and cool the air, and second, it is evaporated by solar heating and distilled to produce fresh water. Finally, the remaining humidified air is expelled from the greenhouse and used to improve growing conditions for outdoor plants. The technology was introduced by British inventor Charlie Paton in the early 1990s and is being developed by his UK company Seawater Greenhouse Ltd. The more concentrated salt water may either be further evaporated for the production of salt and other elements, or discharged back to the sea. The seawater greenhouse is a response to the global water crisis and peak water. History Process Applicability Other benefits Locations
Al rico Bocashi | Blog Disidente ¡Hoy se publica la primera receta de Blog Disidente! ¿Te atreves a adivinar qué plato se merece este momento de especial atención? ¿Quizás un kéfir de leche cruda? ¿O un guiso de vaca a pasto? ¿Qué comen las plantas? Que las plantas comen es un hecho más o menos conocido por todos. El suelo en la agricultura industrial Para entender la importancia de la receta de hoy, es vital conocer cómo se hacen las cosas en la agricultura convencional o industrial. Jairo Restrepo observa la desolación de un campo de cultivo de lechugas en el sur de España. Un suelo sin vida Deja que enumere lo que ese suelo no tiene: minerales traza (que no por estar ahí en pequeñas cantidades son menos importantes), materia orgánica, microorganismos beneficiosos, agua, aire, lombrices, pequeños vertebrados, en una palabra…. El bocashi, un abono fermentado para recuperar la salud del suelo Bien, pasemos a las soluciones. La palabra “bocashi” proviene del japonés, y significa “materia orgánica fermentada”. Receta básica
Green Energy "Oasis" to Bloom in the Desert? A renewable-energy "oasis" slated to be built in 2010 may serve as a proving ground for new technologies designed to bring green living to the desert. The planned research center is part of the Sahara Forest Project—but that doesn't mean it'll be built in Africa. Sahara means "desert" in Arabic, and the center is meant to be a small-scale version of massive green complexes that project managers hope to build in deserts around the globe. (See pictures of the planned Sahara Forest Project reseach center.) Experts are now examining arid sites in Australia, the U.S., the Middle East, and Africa that could support the test facility. "The Sahara Forest Project is a holistic approach for creation of local jobs, food, water, and energy, utilizing relatively simple solutions mimicking design and principles from nature," said Frederic Hauge, founder and president of the Norwegian environmental nonprofit the Bellona Foundation.

Meet Jordan's New Greenhouse-Power Plant Hybrid A novel combination of technologies that has the potential to turn large areas of desert green, producing commercial quantities of food and energy crops, fresh water, and electricity, looks set to have its first large-scale demonstration in Jordan. The governments of Jordan and Norway today inked an agreement to work with the Sahara Forest Project (SFP), an environmental technology group based in Norway, to build a 20-hectare demonstration center near Aqaba on the Red Sea, which would begin operation in 2015. "It's a holistic approach that could be of major interest to a large number of countries," says Petter Ølberg, Norway's ambassador to Jordan. The key to the project is bringing seawater to the desert and evaporating it. SFP combines this technology with a concentrated solar power plant. Under today's agreement, Jordan will provide the 20-hectare site and a corridor to pipe salt water from the Red Sea. Read more in the 14 January issue of Science.
Bloques de tierra!!!! / Soil Block Day!!! | shamballa permaculture permaculture argentina Hoy es un dia hermoso; se siente como si estuvieramos en verano, mas que en el medio del invierno. Un tiempo perfecto para probar nuestro ‘soil blocker’!!!!! Despues de investigar un poco, nos decidimos por una receta para nuestra mezcla de tierra. Preparamos nuestros ingredientes y los mezclamos. We had a beautiful day here, felt more like summer, than the middle of winter. La idea de empezar nuestros plantines sin usar contenedores de plastico es genial….basta de bandejas de plastico!!!!!!. The idea of starting our plants without using any containers is real exciting, no more plastic trays! El proceso fue facil y simple. Ahora, hay que cuidar de que reciban sufiente agua hasta q germinen, evitando q se sequen. The process was easy and simple. We are going to make sure that they receive frequent misting of water to prevent any drying out. Receta para los bloques de tierra de Shamballa 1 parte de turba sphagnum 1 parte de compost 1/3 parte de perlita 1/3 parte humus de lombriz 1 part compost
Seawater Farming | Mission 2014: Feeding the World Problem Seawater farming addresses the severe lack of freshwater and undesirable soil conditions for agricultural activities in coastal regions. Saltwater, instead of freshwater, can be used to directly support a wide range of sustainable agricultural activities and enrich the soils in the coastal regions. Freshwater, which is defined by having much lower salts and ions concentration than seawater and brackish water, only composes about 2.75% out of all water on Earth, and 74.5% of all freshwater are contained in the glaciers, which are not readily available for consumption. While many projects have demonstrated the viability of seawater farming in specific locations, little researches have been done to study seawater farming in a wide variety of conditions. Existing pilot projects are running independently in Eritrea (Seawater Forest Initiative), Mexico (Seawater Foundation, Bahia Kino), the United Arab Emigrate (UAE University) and Australia (Seawater Green House).

El mundo según Monsanto. En español y completo @ReziztenCIA Researchers explore ways to use sea water for farming Al Ain: Sea water is being used in farming research to water crops that tolerate, and even need salt to thrive. If successful, farms along the coastline whose fresh water wells dried up long ago could pick up again giving depleted aquifers time to recharge. Salt-tolerant grass, called halophytes, produced for golf courses or forage for cattle and camels, are the focus of modern farming techniques being developed by the Faculty of Food and Agriculture at UAE University in Al Ain to save water. Environmental economists have highlighted that while domestic agriculture is a serious drain on freshwater water tables in the UAE, arable land is limited and future farming expansion has no potential. According to the Gulf Research Centre agriculture in the UAE accounts for only 2.8 per cent of gross domestic product (GDP), but consumes about 80 per cent of underground water reserves. In Abu Dhabi, the government recently launched a scheme to pump desalinated seawater underground.
