Even though the ecosystem at the Paraje Natural ”Karst en Yesos de Sorbas” possess considerable biodiversity of plants, it is still far away from its climax state. This is a common situation for Mediterranean ecosystems due to the destruction of their original condition and the current vulnerability to erosion and desertification. Nowadays, the capacity of water infiltration is very low and the consequences of wind erosion and water runoff are becoming increasingly visible. It has become difficult to retain water in the landscape, promote water infiltration and develop soils rich in organic matter. Mediterranean plant species are sensitive to these conditions. They cannot prosper and require interventions to improve water catchment and reduce erosion. Therefore, it is important and urgent to conserve and manage these habitats through regenerative techniques of low ecological impact. Figure 1. Before project implementation. IMG_4922-ANTES3 2MB The project took place on 14 February 2013 at “Alan’s land”, parcel within the “Paraje Natural Karst en Yesos de Sorbas”. “Sunseed Desert Technology” Drylands Management department had the cooperation of “Asociación Nuevos Recolectores, Recursos Silvestres /Permacultura Mediterránea”. The project                 was designed and implemented to prepar the terrain for vegetal regeneration. As the first step, we looked at interventions to improve soil conservation. The gullies, where most of the water runoff takes place, were encouraged to distribute water towards areas of less infiltration (the surrounding slopes) to reduce erosion. After preparing the terrain, local seeds were sown to improve dispersal and regeneration of the vegetation. The project also includes as an objective the use of techniques which are low effort and investment and drawing on both modern science and tradtional knowledge. Figure 2. After project implementation Alan LandTwo methods were implemented considering the characteristics of the terrain (orography, soil stability, vegetation, infiltration, accessibility, area, etc). The different methods applied, were designed in order to obtain continuity between each other and obtain as a result a final intervention integrating both methods. They were “Key line” and “Nendo Dango”.A pesar de que el Paraje Natural ”Karst en Yesos de Sorbas” alberga una considerable biodiversidad de plantas, el ecosistema se encuentra muy lejos de su estado óptimo. Esta es una situación común en bosques mediterráneos los cuales han perdido sus características originales y se encuentran vulnerables a los procesos erosivos y de desertificación. Hoy en día, la infiltración de agua es muy escasa y la erosión eólica y de escorrentía son problemas ya comunmente visibles. La capacidad de generar humedad se ha convertido en una tarea dificil así como la recarga de la capa freática y aporte de suelo rico en materia orgánica. Especies autóctonas más sensibles a la sequía no pueden prosperar, y requieren de intervenciones que permitan mejoras en la captación e infiltración de agua así como la lucha contra los procesos erosivos. Es por tanto importante y de cierta urgencia, la conservación y gestión de estos espacios naturales. A través de técnicas regenerativas de bajo impacto y respetuosas con el entorno de los Yesares de Sorbas. Figura 1. Antes de la actuación IMG_4922-ANTES3 2MBLa actuación tuvo lugar el 14 de Febrero 2013 en “Alan’s land”, parcela dentro del “Paraje Natural Karst en Yesos de Sorbas”. “Sunseed Desert Technology” Drylands Management department tuvo la colaboración de “Asociación Nuevos Recolectores, Recursos Silvestres / Permacultura Mediterránea”. El objetivo fundamental del proyecto consistió en el diseño y puesta en práctica de una actuación que permita crear las condiciones adecuadas para una regeneración de la cubierta vegetal. Como primer paso del ciclo de actuaciones se trabajó la puesta a punto del terreno para una conservación del suelo. En las zonas de vertiente, donde se recoge más agua, se ha potenciado la distribución de la escorrentía a zonas de menor infiltración para disminuir procesos erosivos. Tras la preparación del terreno, se sembró plantas locales con el fin de potenciar la diseminación y crecimiento natural del bosque. El proyecto tiene también como objetivo el uso de técnicas de mínimo esfuerzo e inversión, a la vez que integra prácticas de bajo impacto y búsqueda de un equilibrio entre el conocimiento científico y el saber tradicional. Figura 2. Después de la actuación Alan LandDos actuaciones diferentes tuvieron lugar considerando las necesidades del terreno (orografía, estabilidad del suelo, vegetación, aportes hídricos e infiltración, accesibilidad, area, etc). Los diferentes métodos aplicados, se diseñaron con la intención de obtener una continuidad y por lo tanto un resultado que integrara las diferentes actuaciones como un proyecto conjunto. Los metodos fueron “Linea clave” y “Nendo Dango”.

From the 6th to 9th of December 2012 we hosted a course on solar hot water panels. The main objective to the course was to build a solar hot-water panel of two square meters starting with some recycled materials and minimize what is newly acquired. The course, with four participants, was planned and lead by the department of Sunseed’s Appropriate Technologies.

A theoretical introduction included exploration of what impact the use of the sun to heat water might have on reducing fossil fuel consumption and, therefore, on climate change. Then we visited various water heating installations in the town of Moulins, where all houses have their own power generation systems and hot water systems based on various techniques. The practical workshop began with the removal of one of the two solar panels from the main house of Sunseed, which was to be renewed and reinstalled during the course. The materials to reuse were:
  • Copper sheets from old panels.
  • Copper pipes and elbows of various diameters welded together.
  • Tempered glass panel from the former main house.
  • Galvanized iron sheet deteriorated (from the old panel).
  • Glass wool.
The new acquisition was:
  • Copper pipe for collector.
  • Aluminium profile for the frame.
  • Glass wool
The copper plates were initially flattened, cleaned of old tin and re-shaped to accommodate the newly acquired copper tubes used for this purpose. At the same time, test-welds were made with a tin-welding torch to properly assemble the heat-collector. We also prepared and cleaned elbow joints of different sizes for the assembly of the copper pipes. When all the pieces of copper were recovered, and when we were well practiced on welding, the pipes were welded together and the heat collecting plates were adhered. Then we proceeded to paint the heat collector matte-black (to attract sun), and set the paint using a compressed air gun. The galvanized iron sheet was cleaned of rust (where it had appeared after a previous life of 20 years!) and then we proceeded to cover it with zinc paint and an exterior paint-job to give it a little more weathering protection in the exposed parts. The aluminum was cut to the proper size and shaped to the design being done. The rear plate of the frame-sides were joined with rivets, but we left an open side prepared so we could make the final placement of the tubes and glass. The glass wool insulation was placed by sliding it into the frame assembly. With care not to break it, the top layer of tempered glass was also placed. We closed the assembly by finally completing the riveting under the last segment and then applied silicone to give it waterproof joints.

Participants were able to take part in all the processes of panel construction, and they were happy to be in contact with all materials and tools. By using recycled materials and learning the “do-it-yourself techniques”, the participants’ capacity to use such materials has grown – they can be more confident to do it themselves, and be able to avoid using primary source materials or commercial panels, too. We hope they will try it themselves in the future!

Click here to see all the pictures. Del 6 al 9 de Diciembre de 2012 llevamos a cabo en Sunseed el curso de paneles solares de agua caliente. El objetivo principal del curso era la construcción de un panel solar de dos metros cuadrados partiendo de algunos materiales reutilizados, y otros de nueva adquisición. El curso contó con los cuatro participantes previstos y fue impartido por el departamento de Tecnologías Apropiadas de Sunseed. Primeramente se realizó una introducción teórica sobre el impacto que el uso del sol para calentar agua puede tener sobre la reducción del consumo de combustibles fósiles y, por lo tanto, sobre el cambio climático. A continuación realizamos una visita a diversas instalaciones de calentamiento de agua en el pueblo de los Molinos, donde todas sus casas cuentan con sistemas propios de generación eléctrica y agua caliente con diversas técnicas. El curso práctico comenzó con la extracción de unos de los dos paneles solares de la casa principal de Sunseed, el cual iba a ser substituido por el que se realizara durante el curso. Los materiales que se iban a reutilizar eran:
  • Láminas de cobre procedentes de antiguos paneles.
  • Tuberías y codos de cobre de diversos diámetros soldados entre sí.
  • Cristal templado procedente del anterior panel de la casa principal.
  • Chapa de hierro galvanizada deteriorada por el tiempo procedente de otro panel.
  • Lana de vidrio recuperada (parte).
El material de nueva adquisición era:
  • Tubería de cobre para el colector.
  • Perfil de aluminio para el marco.
  • Lana de vidrio (parte).
Las láminas de cobre fueron aplanadas primeramente, limpiadas de antiguo estaño y vueltas a conformar para alojar el tubo de cobre adquirido nuevo a tal efecto. Paralelamente, se fueron realizando pruebas de soldadura con soplete y estaño de cara al montaje final del colector. También se limpiaron y prepararon codos y uniones de diversos tamaños para el ensamblaje de las tuberías de cobre. Cuando todas las piezas de cobre estuvieron recuperadas, se soldaron las tuberías entre sí y a las láminas colectoras de calor. A continuación se procedió a pintar de negro mate el conjunto usando una pistola de aire a presión. La chapa de hierro galvanizado fue limpiada de óxido en las partes que éste había aparecido (tras una vida previa de 20 años!) y se procedió a cubrir con pintura de zinc las partes de hierro expuestas. Posteriormente, se le aplicó una capa de pintura para exteriores de cara a darle un poco más de resistencia a la intemperie. El perfil de aluminio se cortó con la forma y medida adecuada al diseño que se estaba realizando. Se fueron ensamblando la chapa trasera con los laterales del marco, uniéndolos con remaches y dejando un lateral abierto preparado para la colocación final de los tubos y el vidrio. Se colocó la lana de vidrio aislante y se deslizó al interior del marco el conjunto del colector. Con mucho cuidado para no romperlo, fue también colocado el vidrio templado. Se terminó de cerrar el marco remachando el último segmento a través del cual se habían introducido los componentes y aplicando silicona en las uniones para dotarlas de impermeabilidad.

 Curso Paneles Solares Agua Caliente Sunseed

Cabe destacar el valor que tiene el que cada participante haya tomado parte personalmente en todos los procesos de la construcción del panel y el haber estado en contacto con todos los materiales y herramientas. Al utilizar materiales reciclados, el contacto del alumno con ellos es mayor que en el caso de utilizar materiales de primera mano o adquirir paneles comerciales. Este contacto ampliado, dota al alumnado de experiencia que le capacita para repetir los procesos por sí mismo en el futuro. Pako Ibáñez, Corrdinador de Tecnologías Apropiadas en Sunseed.

It had been a few days that members of the Community of Sunseed had been discussing the possibility of going to pick mushrooms in the forest. Although this activity is normally considered as a fun thing families do on Sundays, we wanted to view this more as a way to take advantage of the nutritional resources that the forest offers us during the fall with the appearing of various types of edible mushrooms. Nevertheless there were a lot of unknowns: Where can we go? There aren’t any forests in the vicinity of Los Molinos. Will we find enough mushrooms to make it worth it? It wouldn’t be the first time that we haven’t found any mushrooms. Will we find mushrooms that we know we can eat? These being milk caps, boletus and a few others. We wanted to avoid having to pick any other mushrooms of which we weren’t totally sure of as it would be a loss for everyone if we had to throw them away later on. Jose heard about some mycoligical days in Abla, in the hillsides of Sierra Nevada. A village named Abrucena is situated a few kilometers further up. This is where the first forests of repopulated pines that cover the slopes of the mountain until the very top can be found. The place can be reached by car in an hour, which seems reasonable for a one day excursion. We then formed two teams, Team number one that was responsible for the hunting of the mushrooms and Team number two which had to stay in Los Molinos waiting for Team number one to bring back the mushrooms so that they could clean, cook and finally put the mushrooms in jars as a way to preserve them. Would we gather enough for it to make sense to preserve them? Would we have enough for the whole year or just for the winter? There wasn’t any other way than to go out to Abrucena and hope for the best. Call us pretencious but we left early one morning in the direction of Abrucena with plenty of boxes ready to be filled by the precious and tasty mushrooms. Sunny weather awaited us in the part of Sierra Nevada where the supposed hidden treasure was to be found, even though we could see a group of clouds starting to cover the sky. We passed the town Abrucena following a small road which brought us to the forest. We decided to stop at a recreative area which looked so nice that it made us think that mushrooms had surely made their home here. This part of the forest is situated on the bottom of the area of forest exploitation as the undergrowth is basically clear of vegetation. One minute after we’ve looked around a bit we find the first milk cap, a few seconds later the first colony. Everything is right next to the parking of the recreative area! What is happening? The thing is, that day was Thursday, everyone was at work and the mushrooms had time to grow since the last week-end. Then the hunting began. Those who had a certain experience in picking mushrooms knew where to look for them: in a mountain of pine needles, in a humid area or underneath certain branches for example. The novices slowly started to figure it out. We found a lot of colonies which created emotional moments of harvesting. At one moment I called Trudy to tell her to come and have a look. I revealed to her that there were at least ten mushrooms located no more than two meters away from us, the first one just a step away. Yet she could not see them and I therefore started pointing out the mushrooms which brought out the question of “where do the mushrooms hide?”. Sarka recognized a type of boletus which is much appreciated in her country (Czech Republic) and promised she would use it to make a stew for us. Kirsty got more and more animated during the hunt and with the basket around her shoulder collected abundant amounts of mushrooms while searching the corners of the forest. David went up and down the slopes dragging along a plastic bag which got fuller by the minute. Jose was in his environment. It would have been easy to confuse him with an inhabitant of the forest. Natalia the dog came and went without knowing who to follow. Trudy looked amazed from the experience and was making the most of it. I have to confess that I was enjoying it like a little child. It had been many years since I had last gone out to pick mushrooms. This goes without mentioning the intensity with which we harvested on that day. During the previous days I had insisted that the term “hunting mushrooms” was more appropriate than “picking mushrooms”. Now you could understand why. Every one of us was moving around fully concentrated through the forest observing the ground in search of clues which would indicate us the location of the mushrooms. Our senses were put up to the test: our sight, our sense of smell and touch as well as our minds. You take the knife in your hand and cut at the foot of the mushrooms which is then exposed and identified as “good”. There is a relationship that creates itself between the environment that offers us a resource and us who are trying to obtain it. If it was simply “picking mushrooms” it would be more like harvesting a fruit off of a tree. This implicates that you have only to reach your hand to pull the fruit off and place it in the basket. But with the mushrooms it is different. They are not waiting there for everyone who passes by to be able to collect them. It requires physical, mental including meditational work which makes the experience unique. That day of “hunting mushrooms” I would define as complete. First a few hours of walking in the mountain collecting numerous mushrooms. Then a barbecue in the same mountain to cooking the fresher and younger ones. Later we went back home and prepared the rest of them to be preserved. For the more than twenty kilos of mik caps that we brought home, each and every one in perfect condition and without any worms, the task of preservation was going to require a lot of labor. Fortunately, the friends and volunteers of Sunseed mobilized themselves immediately and started the hard tasks of cleaning, cutting up, cooking and preserving the mushrooms as soon as we arrived. We sautéed most of the mushrooms with oregano, salt and pepper in the olive oil. With its own delicious juice we placed the mushrooms in jars and cooked them a la bain marie. The smaller, tender and nicer ones were sweetened with wine and spices. These were then eaten as an appetizer later on. The following week we returned to the same place, this time on a Wednesday, and we had another successful harvest. The harvesting of mushrooms is an activity where we make good use of the forest. It mixes the ludic side with sustainibility and makes up another source of tasty food that can be obtained. Hacía días que se iba comentando entre algunos miembros de la comunidad Sunseed, la posibilidad de ir a coger setas al bosque. Si bien esta actividad se considera normalmente como lúdica (e incluso dominguera), el enfoque que se le quería dar era más próximo a aprovechar los recursos alimentarios que nos ofrecen los bosques en el otoño con la aparición de diversos tipos de setas comestibles. No obstante, se planteaban diversas incógnitas: ¿dónde podemos ir? En las cercanías a Los Molinos no hay bosques; ¿habrán salido suficientes como para hacer una buena caza? No sería la primera vez que no se encuentra ninguna seta en una salida. ¿Encontraremos setas de las que conocemos? Básicamente níscalos, boletus y alguna otra. Queda fuera de la intención recoger ninguna seta de la que no se esté totalmente seguro y luego tener que despreciarla. Read MoreContinue Reading
