A technical training manual supports all theoretical information, which is the compi- lation of informative documents and bibliography on the subject. At the Taliscas Activity Centre from Matriz, where the theory sessions took place, a significant set of books and other materials is available for consultation. The most significant practical component of the training action consists in an inter- vention on an existing building in advanced degradation level. Based on the theoretical information just acquired the analysis of the building is undertaken: main pathologies are identified, as well as its causes, and the interven- tion strategy is defined.
Teams worked in a rotating scheme, therefore allowing all trainees to take part in different tasks, thus distributing Figure 1. Survey and analysis of the case study. The accumulation of debris from the deteriorating structures also con- tributed to raise the floor level, which debilitated even more the wall base.

Conservation and New Construction Solutions in Rammed Earth
Conservation works. The solution to remove the insects was to spray with lime-wash also used to consoli- date fragile areas lacking in cohesion. On the opposite wall the raising of a second stiffener was initiated that will be finished in the next training session. Therefore it was pro- posed to partially close the existing span through the building of a stretch of wall on one of its sides.
A similar to the original earth mixture was pre- Figures 4, 5, 6. Earth and earth-lime renders pared, corrected with different built photo: Susana Sequeira. On the deeper ones the filing was made with the attached rammed earth technique using similar mortar but with thicker sand to which gravel was added. It covers its characteristics, production, slating and application method as well as the best way to be associated with rammed earth and plastering.
The focus of these trainings was the Conservation of Rammed Earth Construtions I, II Odemira Council region, from where almost all trainees were from, in the first geographical origin Castro Verde session. Our short-term ambition, thus continuing this type of trainings, is to create a more exhaustive and complete course where, with a multi-skilled set of technicians and workers, we can actually rebuild and restore an existing building, covering the whole process.
As a starting point, the analysis and assessment of the building, then the execution of a project by technicians in close interaction with workers, and finally sharing and discussing ideas. Finally, the workers, in collaboration and active participation with technicians, will take on the execution of the building project.
This way all the project and building process questions will be approached by both parts and the restoration work can be concluded. We believe that earth building on the rural context, which we integrate, can repre- sent a quite significant development factor with unique impact on the territory.
Construction workers trained with the appropriate skills are needed in very large numbers. They should not only be able to practice these skills but should understand the necessity of their interventions and take pride in their achievements, as a first step leading towards further personal development. At the moment there is still not enough time to assess correctly but we can already observe, though quite informally so far, successful cases of small contractors that ini- tiated their activities in this building technique that is having increasing demand in this area.
Matriz is engaged in continuing to expand its activity with the scope focused on earth construction, namely through the creation of a resources centre on the Taliscas Activity Centre. Bibliography AA. Houben H.

And what a risk worth taking. The farm succeeds in attracting volunteers from all across the globe, all backgrounds, all ages. In fact, during my stay we were accompanied by a young couple from Belgium as well as a retired woman from Canada. During their stay, volunteers get the opportunity to work on a variety of projects, generally suited to their interests and abilities, and depending on what needs to be done at that particular time of the year.
Because our group was quite big, we were split up into smaller teams who worked on everything from gardening, to digging, to building a compost toilet. And believe me, no experience was necessary. Volunteering to work on building a bench from scratch, I was reminded that my only carpentry skills were those I acquired in childhood…building with Legos. Garcia says that he hopes that such experiences will allow volunteers to immerse themselves into the sustainable lifestyle and teach them practices that can be applied back home.
Although the work is challenging and the Costa Rican sun does not spare any mercy on Caucasian skin, engaging in such sustainable projects is immensely rewarding and proves that a green lifestyle is attainable.
What started as an unsure venture has turned into a green haven. Photo by Sean Hill. Trees Forever is an organization with a mission to plant and care for trees and the environment by educating organizations and individuals about the need for forests and promoting stewardship of our natural resources. Trees Forever has created numerous programs across the nation since its inception in , pooling resources from donors and sponsors to fund and assist with grassroots projects. One such project is the Illinois Buffer Partnership, a program in conjunction with the Illinois Farm Bureau, in which landowners can apply for funds to help create buffer projects on their land.
Farmers, rural land owners and those near watersheds find it a worthwhile program to slow runoff from fields, reduce soil erosion, filter and purify water, increase wildlife habitat, create visual screens, and, in turn, produce more farm income from that land. Those interested have until the end of the year to apply for the funds, and will be notified in February if they have been selected as a participating landowner. Another Trees Forever project in the Midwest is the Iowa Living Roadways Community Visioning program in which small rural communities in Iowa of 10, residents or fewer are eligible to get access to professional planning services for landscaping roadsides, entranceways and trails in their communities.
Iowa State University is a partner, providing teams of landscape architects, student interns, faculty and staff to assist in creating concept plans. Once completed, Trees Forever assists in carrying out the projects by providing funding sources or grants available for such work. Communities that participate benefit greatly from the work of volunteers who are able to include environmental stewardship into concept plans and projects that essentially enhance the beauty and safety of areas in which residents drive, walk or bike daily.
Soil erosion hits close to home, and has global implications, as well. The United States has been leading the fight for nearly 80 years. During that same time period, NRCS hosted international participants from other countries who observed what was taking place in the United States to combat serious soil erosion and land-use problems. This sharing of conservation knowledge led to an ongoing exchange of the best ways to address soil issues.
There is little doubt that international programs help all countries utilize natural resources without depleting them by sharing technical assistance, exchanging scientific and technical information, and helping promote economic stability at the same time. In many countries, the care of soil results in better and widespread food production, which in turn helps reduce poverty and social issues related to hunger and poor nutrition. Because Fort Hood covers , acres and endures the largest concentration of armored tanks and vehicles conducting training sessions in the country, researchers are dealing with compacted ground, loss of plant cover and accelerated soil erosion that results in excess sediment in streams and lakes.
The research resulted in the creation of 30 more sediment retention ponds, construction of numerous small rock dams to block gully erosion, and the practice of plowing deep into the ground on a regular basis to prevent soil from becoming too compacted for plant life. When compost and grass seed can be added to new contours of previously rough terrain, it results in vegetation buffers and far less water run-off. Research like that at Fort Hood leads to new land management and agricultural practices that spread around the world, saving countless acres from erosion that renders them useless.
It is possibly the easiest item to just mindlessly toss into the garbage can because as you are discarding them your mind is usually focused on the task of replacing them at nearly the same moment. But they are just as easy to recycle, thus cutting down on the chance of polluting lakes and streams, and exposing the environment and water to lead and acid.
Household batteries contain all sorts of heavy metals — cadmium, lead mercury and nickel — which are a detriment to the environment when they turn up in landfills. It has been estimated that more than 2 billion batteries end up in landfills every year in the United States. When you consider that Americans buy billions of dry-cell batteries every year to power radios, toys, cell phones, watches, laptop computers, and portable power tools, it is apparent we are nearly overrun by batteries.
In addition to keeping harmful elements out of the land and air by recycling batteries, it can also result in saving resources by recovering the plastics and metals that can be used to make new batteries. Alkaline batteries, the everyday household batteries used in flashlights, remote controls, and other appliances are prime candidates for consistent recycling efforts, as many cities and counties have recycling programs and several reclamation companies now process these batteries. Button cells are increasingly targeted for recycling because of the value of recoverable materials, their small size, and their easy handling relative to other battery types.
Many states have battery-recycling laws in place, but a habit of recycling your household batteries can aid the environment, regardless of any mandated regulations. Check to see if your city or county has drop-off locations for old batteries. Many cities allow battery recycling by simply placing the old batteries in bags and putting the bag on the ground near your regular recycling bin. In many states, the larger lead-acid batteries from autos, boats, and sump pumps can be taken to any store that sells these batteries.
The stores will take these batteries for free or a small processing charge. Then the batteries are totally recycled, including lead plates, battery acid, and the plastic cases. Not so fast, my amateur environmentalist. It has been shown that organic products may be better for health, that is true. But a recent study has shown that when it comes to being eco-friendly, organic farming may be sub par. Research from the University of Guelph in Ontario, Canada, reveals that in some instances, organic pesticides can be more detrimental to the environment. The study says that it is wrong to assume that just because pesticides are organic, means that they are better for the environment.
In fact, the opposite may be true. Oftentimes, growers have to use larger doses of the organic pesticide to get the same effect as using synthetic ones.
The study measured the effects of six pesticides used to kill soybean aphids: four pesticides were synthetic, two were organic, one mineral and one fungal. Using criteria such as toxicity to humans and wildlife and leaching rate into soil and water, the study concluded that the mineral and fungal pesticides were less effective and more destructive.
One particular harm noted from the organic pesticides is that they were harmful to ladybugs and flowering plants which are necessary controllers of aphid population. This example is only one of hundreds in which organic products could have an unexpected flaw. It is important to pick products that are natural, but they should also promote environmentally friendly practices. This case illustrates perfectly how the end product could be deemed organic, but the practices in place to attain the product are less than green.
