While preparing our training, we were experiencing a terrible situation, a pandemic threatening all of us, whatever our origin, age or wealth. Most of us had the scary experience of a lock down. People were afraid, most economic activities had stopped and we were all confined inside, waiting to see what would happen next.In the same time, in what seemed like a parallel universe where we hadn't discovered we are all equal in front of a common health enemy, strange words kept popping up. Brexit, Grexit, Polexit, Italeave, Departugal... Some of those words were real, some only in the dreams of their supporters and some had been made for entertainment purpose. only. The fact is that even if some researchs showed a resurge of european citizens trust towards the EU (view for example https://www.pewresearch.org/global/2019/10/14/the-european-union/ "Across the 14 EU member countries surveyed, a median of 67% hold favorable views of the European Union while 31% have an unfavorable view.") there were also big waves of separatism accross the EU countries, trying to convince citizens our Union is the cause of every social economic and political harm.While it cannot be denied that any pandemic is a disaster, we strongly believed it would have been criminal and an insult to the victims to not grab this opportunity to reinvent our society as we know it with the proposal of sustainable models. While some of our other projects focus on nature per se, we decided to go one step further and analyse one of human's main needs, shelter as it became dramatically clear than while the WHO (and most governments) advised for a lock-down, some people didn't have anywhere to isolate. And those people were already the most fragile of all.A few years before the covid-19 crisis, started what we now know is the Worst Refugee Crisis in History. More than a million migrants and refugees crossed into Europe in 2015, sparking a crisis as countries struggled to cope with the influx,and creating division in the EU over how best to deal with resettling people. (https://www.care.org/emergencies/global-refugee-crisis)While the full impact of the COVID-19 pandemic on wider cross-border migration and displacement globally is not yet clear, UNHCR data shows that arrivals of new refugees and asylum-seekers were sharply down in most regions – about 1.5 million fewer people than would have been expected in non-COVID circumstances, and reflecting how many of those seeking international protection in 2020 became stranded. Despite COVID-related movement restrictions and pleas from the international community for a ceasefire that would facilitate the COVID-19 response, displacement continued to occur – and to grow. As a result, above one per cent of the world’s population – or 1 in 95 people – is now forcibly displaced. This compares with 1 in 159 in 2010. (https://www.unhcr.org/flagship-reports/globaltrends/)Lesbos has been over the past 5 years one of major points of tension in Europe. The Moria Refugee Camp, is cited to be one of the worst in terms of hosting and sanitary conditions. Constructed for 3,100 people but at times with a population of more than 20,000 men, women and children with over 100 people sharing one toilet. People seeking refuge and life opportunities in what they see as a haven of human rights and safety, Europe. These thousands of vulnerable people spill out into the surrounding olive groves in makeshift tents, which were elevated on wooden palettes to try to prevent the cold from the freezing ground seeping into their tired, aching bodies. After Moria burnt, they were locked in an even worse situation. Our training aimed to give youth workers the opportunity to discover and implement the construction of sustainable shelters, locally-sourced living spaces, harmoniously integrated into the surrounding ecosystem. The materials common to many types of natural building are clay and sand which are easily found everywhere. When mixed with water and, usually, straw or another fiber, the mixture may form cob or adobe (clay blocks). Other materials commonly used in natural building are:earth (as rammed earth or earth bag), wood (cordwood or timber frame/post-and-beam), straw, rice-hulls, bamboo andstone.(Wikipedia) As a response to all the "exiters", out there, we wanted to combine social permaculture by "building" a community that included people of diverse ages, genders, races, sexual orientations, physical abilities, and economic backgrounds, as well as diverse ideas, cultures, and opinions, who would have broader perspectives and a deeper understanding of issues and events, as well as more resilient responses. (https://www.ic.org/social-permaculture-what-is-it/) and natural building, in a way of showing everyone that human beings, as different as clay, water, glass, stones etc can get together and make something strong and beautiful.
