A personal level and i was unable to live there which im going to. You want to know their story in full really great story finding interim i will information for margarets. Germany is celebrating its 30th anniversary of reunification in 190 west germany and east germany reunited to become one nation what was it like join us and shift today to take a virtual journey through time. This is what the berlin wall look like and unbreachable stone obstacle on the close god dividing the city for most citizens of the g. D. Are leaving the country for west germany was not possible you had to go. To extreme lengths to flee like digging underground tunnels using Virtual Reality its now possible to experience what it was like when people try to escape and one from khosla got to experience what it was like for his grandfather who dug a tunnel underneath the berlin wall. This man in this picture is also measured from clothes that hes my grandfather and in this picture you see him building a tunnel under the burden wall using of your goggles and on coast and social historian and at that period of time traveling back to the year 964 for the you choose show virtually history. I can see in his eye that he has a plan. Just a few years now but younger is this weird its like pretty much travelin in time in 164. 00 close Michael Vaughan koestler and some friends dug a tunnel from west berlin to eastbourne and they wanted to help people to the g. D. R. It took them 6 months of digging and secrets to complete until you can experience the tunnel in virtual space 12 meters deep 145 meters long the young tunnel builder from back then is now a pensioner when close Michael Vaughan coarsely sees the virtual video of the berlin wall and tunnel it brings back memories from lighting 64. This. Way an exhausting. Especially on the knees are always covered in scratches and then to move or. Sometimes we had to lie during the day or in constant fear of the tunnel lapsing part this often pop through the spite of the risks the plan works out 57. 00 men women and children were able to flee using the term which is a place in the history books. And the famous story was the mother in family 6 going through a house that stood directly at the parent this could also be relived on you tube was virtually history. Timing it offers virtual boosters exploring east berlin when it was still part of the g. D. R. The bus passes by buildings that no longer exists today which is interesting to locals. Travelling through checkpoint charlie the Border Crossing point between east and west is particularly interesting. I think the most frequently asked question is actually where is the wall. And its of course an enormous responsibility to present and to make this experience relive a ball. But its also a chance to encourage people to think about what they are like them and what lessons we can learn from. Them and also its an impressive images today it really does look very different. Is a scholar of Cultural Studies at university in berlin and Kings College in london she looks at the ways in which we are can make history more vivid we ask how effective technologies like Virtual Reality truly are in bringing history back to life i think these formats work really well and considering how they are becoming more common for personal use it makes sense to use them for educational purposes but its important to have people there for support and supervision. Thats at a disadvantage is that Virtual Reality is designed to completely envelop and recreate an intensely emotional situation. This can quickly taking on a position that can be quite problematic especially in historical. Is a very Emotional Experience perhaps its too emotional of an experience to be used to teach history objectively luckily theres another way to time travel games in the adventure game the berlin wall players have flee the g. D. R. The developers of the game hope that it can help educate young people about what life was like in the to tell a tarion state now when exactly was this wall thats probably the most frequently asked tourist question. A are can out without. Suddenly the spike complete with border patrols tanks and watchtowers. Using augmented reality technology. Displays that virtually on your smartphone or tablet. You can even jump through the decades and see how the border. Was transformed from a barbed wire fence into a concrete wall this. Is the most fascinating moment for me is when you put your phone aside and you still have this lingering impression that the objects are still there and that is connecting history to reality in a way thats impossible to do with a book or a movie. The berlin wall was located just a 10 minute walk from our studio here obviously test the b. F. Already its pretty interesting but im not fully convinced yet even though it provides spatial imagination of the walls border during a different historical period im sticking with photographs of course theres more to the g. D. R. Than the wall citizens dont like having their lives reduced to that if you would like to take a more personal look at everyday life in the g. D. R. The project open memory box might be for you a german argentinian filmmaker and a. Political scientists got together to archive and digitalize home movies recorded from legend 47 to 990 and now publicly available its their contribution to a more comprehensive understanding of life and the g. D. R. Life in the g. D. R. 8 millimeter film personal memories spending 4 decades 7 years ago lawrence befalls and Alberto Herskovitz made an appeal in the newspaper for 8 millimeter films shot during the g. D. R. They never thought that they would be able to collect more than 2200. 00 rolls. 415 hours of film have now been digitalized been archived and published on the open memory box website you can filter your search if it date or let yourself drift through the. Selection terms like freedom hobby or yellow goosey 2 2nd film snippets repeatedly recombined randomly. And these 2 seconds are losing many stories and so thats something that Digital Technology allows. If you look at the clips one after the other it changes. And its a little bit different. Has a different effect i just wondered if you. Just sent. These or videos that people innocently shot for themselves or their family. And thats the big difference compared to our behavior today of course. We also film our surroundings our children all the food we and the places we travel to. But the difference is that were also always aware that we might post or share these videos. Whereas this material on the other hand was never intended to be shared widely. But falls and ask if its visited the people who need or films or a. Appeared in the videos. They were then asked to come and. Sometimes at night i would dream of going to west been to see what it was love. Open memory box a more personal and unique glimpse of life in the g. D. R. And whats offered in history books what a great project but for some memories of live in the g. D. R. Less pleasant the ministry of state security or stasi spied on its own citizens when it became apparent that the g. D. R. Was ending they tore up the stasi records but not completely 600000000 scraps of paper were left. Now Artificial Intelligence can help to reassemble them. The computer is doing this puzzle using the sky and fragments of. 600000000 little pieces are stored in the archives and then you fraction of them have been digitalized it would take centuries for humans to complete this puzzle and thats why the puzzle was invented. And. Size of the fragments was a very special challenge there was for example and. Which was torn into a 143 pieces and the e. Puzzler was able to handle this challenge really. Is the creator of the. Setting Machine Vision at the institute for Engineering Design in berlin since the eightys its a technology that enables computers to recognize and identify objects even without a template. Vision is necessary because there are many visual processes where human beings are unable to. Mission like medical actually images for example of. Machines are more effective than humans in processing large amounts of the. Pieces and complex shapes like the tool that. Does the software. Each piece memorizing content paper type these classic. Self learning algorithms reassembles those thesis that have been identified as belonging to gether. Pilots. 23 bags filled with people scratch was the 1st they had to be digitized that soaring 700000 little pieces. Was able to reassemble. Even though the software was working the scan it turned out to lack the necessary precision. That would enable greater precision but they couldnt get the necessary. Even though they no longer scanning. Technology is being used around the world today a program very similar to the president has been used to put fragments back together that weve destroyed like these from the 1900. Community center. Or these books and documents from the cologne city which collapsed in 2000. There are still thousands of bags full of shredded secrets in the stasi documents archives waiting for a machine to put them back together again finding the right puzzle piece from 600000000 little pieces its impressive what i can do to me projects like v. R. Time right make history more tangible i also remember more details what do you think which project impressed you the most and what time period would you like to travel back to.

Hello and welcome to another edition of eco africa im now a time where i have the Conservation Foundation in Lagos Nigeria this week we have some really interesting reports on farming conservation and art lets welcome my cohost sandra hi there sandra hi amy a hello everybody from me to here in the capital of uganda i am so excited for this weeks episode of africa will report comes from western africa to be more precise from ghana but fost lets take a look at other stories coming up over the next. We look to help conservationists. Great. Also see how people. Are rebuilding their lives devastated last year. And how some african artist. Weve. Inoculating see sounds weird doesnt it but with this method farmers can minimize the use of even organic fertilizer it is one of the several new eco friendly techniques that film was in northern uganda and learning from mohamed and hes the train has explained the complex science in simple terms small for the farmers who called taken up the courses say they will have improved significantly. Here in the northwestern part of ghana mainly cultivate soybeans. Out in the fields to care for full hectares of land. 4 years ago fertility parts in a Training Session for Sustainable Agriculture since then have cropped a profit have increased. In. Addition to farming shares recently established and 2nd business she sells traditional textiles in the communities around her village to linger. I used to have 2 or 3 backspace pussies i started using the North Koreans its 7 to 8 bags. And after that she learned how to inoculate seeds during a Training Session conducted by the local Company Green e f today the farmers engine jody cool also taking part. In the met that is simple the seeds are stirred together with water and sugar before dried grizzle bianchi had bacteria added bacteria keep past the way each cow pct must be more just. Once dried the inoculated seeds must be sown at precise distances to one another thanks to this method the farmers no longer have to use chemical pesticides. More than 500 farmers have been trained by the company so far no harm is the chief came up with the idea for the Training Sessions he actually studied business but soon switched to agricultural philosophy. His team instructs the farmers and how to run their farms in more sustainable ways such as by using the plant cremains for compost or bio coal the fabrics of kidnap plants for example i especially well suited to enriching depleted soils. Projects and then a war so how produced by you which is very good soil. Properties like so i dont want to hoard it by sitting and its really different also pollution so i was at a point i mean it had would have been made out like. I use that door to do that. Most farmers in ghana used chemical fertilizers and pesticides which has worsened the quality of the soil this gave eco printer such a reason to search full turn it serves the farmers can even test the make up of the soil if needed samples that then sent to the companys own lab. Although the Training Sessions for the small scale farmers are free the sole analysis comes between one and 30 euros depending on what exactly is being tested for farmers its worth it because they learn exactly what this soil needs improvement the use of a 6 if you know that maze is preventing leeching of some of these excesses underground what about the runoff into surface whatever these core Simple Machine since they are the source of what that form and the mass and i dont even understand since having his soul tested pharma just shut conlan really uses fertilizers anymore before the analysis he found exclusively soybeans but now that changed. In the 3 years ago when i started self testing with and. I produced their commend it to me and then my results doubled i got 70 bucks more. From us i always got on the fold and this has helped me to be able to acquire. A farm tractor which is helping my production. Just short conlin expanded from small to medium scale likely culture for the really cool isnt quite there yet but shes well on her way. From ghana we crossed the continent to kenya to check out a project that is full of bots well somebody anyway a Conservation Organization has made it eats nishan to fight for the survival of one species in particular that. Thats right sandra like so many of our feathered friends crowned cranes i would risk due to habitat loss and poaching now a Community Based ngo is informing the farmers children and others about the importance of protecting these majestic creatures. Wherever the currents go George Newman is not far behind he leaves nearly called bull site in Central Kenya the local conservator hist is passionate about birds and founded the cranes Conservation Volunteers organization he regularly visits their habitats to monitor their activities. I need to be with him if we see this crazy allow is an indicator that can help heal the rift you know and also that calls for protection that we have something here that these groups and not just koreans can attest to that the area is home to the largest population of gray crowned cranes in the whole country over the years grain populations have suffered a major decline as a result of human related activities like trampling of chicks by dr stock poaching from it both local and commercial level and collection of eggs but the cranes also disturb the farmers living around the lake which will be how we. Get the Winter Garden to us you know how did we can exist with the corn cranes on our farm the very destructive when we plant crops they take the seeds you get 200 more you know immediately and without so much youre like the plants they peel and eat him too they eat from the who farm. How did they needed only 2 or more that. Reducing conflicts between humans and wildlife is the main work of georgia dome. And his team mates regularly with farmers the conservationist explains that cranes also have a positive impact on the crops as they eat worms which normally destroy the young plants when have its time approaches then carried them to got their funds to protect their crops even convinced porches to become volunteers on his team. You know when i fish at the lake i take care of the crew and cranes in accordance with the government regulations you go on go. On are you girl but you are. What are you the birds attract tourists and when they come here they have to develop the area and create masteries for school children. Thought or could be. So much. Why not do it. Volunteer conservationist also visit schools in the region twice a month this time hes at the market wrecker Primary School where 3 children received this masteries all together 32. 00 best stories have been provided by the Development Fund the lake also became a protected area last year the queens breeder to show from july to february just before the breeding period starts the quince Conservation Volunteers try to coordinate with farmers to democrats important breeding areas by the lake sometimes community to cooperate in other times the time because when. We tell them to exclude the livestock during the great season and during the dry season theyre faster i would say the lake it is minimal so thats a lead them to bring their cattle describes how those judged works tirelessly to mediate with locals and keep the area protected for the benefit of the great quantity grains and the local population who will benefit from the growing eco tourism. You know they are really amazing its terrible the risk of dying out because of the loss of their habitat we see its important to preserve Natural Habitats and a logical balance in tanzania a No
