Countrys lifeline. But first we have to china where Migrant Workers are being ousted from cities on mass where will they go. Migrant workers make up a third of chinas labor force they are people who leave their villages and head to the metropolises in the hope of finding a decent job for years they were absorbed into city life after all they were a key factor in chinas economic miracle but many are still treated as third class citizens and arent even officially registered its estimated that there are two hundred eighty two million Migrant Workers across china beijings population alone has trebled over the past twenty five years Authorities Say its too much they want millions of the Migrant Workers to leave. These Migrant Workers have been evicted from the. Homes in change village on the outskirts of beijing they have to be out by dawn. Mistily you has to find shelter for himself and his workers he came to beijing twenty three years ago and eventually became the owner of a small textiles workshop now they have to pack everything into a truck and leave tomorrow the building could be demolished. Two weeks ago there was a fire here in one of the buildings. The next day officials told us we had three days to leave. I said three days its impossible weve got no idea where to go. With a. Part of that would be. Gas and electricity and water was shut up straight away despite freezing temperatures outside that it will officially they say the buildings have to be vacated for fire safety reasons but the residents suspected something more sinister that beijing wants to get rid of its socalled low end population. Daylight reveals where it all began the fire broke out in this building nineteen people died after that the government hastily drew up a forty day plan to evacuate all the illegal and unsafe buildings and structures in beijing. Many believe its a plan to drive the ten thousand affected out of the city. One gun chung comes from the impoverished apartments of councell and works in beijing ironing textiles. We have to be out by this evening and i really dont know where to go. A feeling of hopelessness permeates the entire workforce of the factory. Many people have been here for decades doing work that people from beijing wouldnt do they have no rights because no one has a beijing residence permit now they have just hours. To pack the things i want its not fair they should have given us more time at least but i dont when i am not here those i came here in search of a better life far from my home i was very ambitious now i just feel sad because i have no other choice i have to go. On the outskirts of beijing chingy on villages being demolished all thats left is to pray and. The old town has been disappearing for months theres nothing left for the Migrant Workers who built themselves a life and. Its caused an uproar among the beijing population but the photos and videos uploaded by bloggers quickly disappeared from the internet sunset by the state. One group uses an online map to show you where the affections of taking place across speccing they call it a map of Fire Protection measures as a way to avoid censorship. Support groups have also sprung up like hair in west beijing. An artist group wants to turn the cell is into accommodation for the Migrant Workers to get a bed and shelter to these people who give so much to the city. The phone will be and always. A home of the workers of established Small Convenience stores in our neighborhood like the fruit vendor in the little shop on the corner they make our lives more comfortable. That come and go in the bottle and. These office of support are being closely monitored by the government because theyre afraid that criticism could lead to protests. This small village lies in her base the neighboring province of beijing. Migrant worker liu and his employees are staying here temporarily but theyre not really welcome. In the village there even official announcements warning not to rent to textile companies because of the fire risk thats on you know the two thousand and eight Olympic Games in beijing said everyone was welcome even us now weve just been discarded its so cruel that i see that. We are going to the evictions in beijing the year has only secured himself a temporary refuge the next step is still unclear. If we do we made a life in beijing as Migrant Workers because we had no better option. Now we just get thrown out wherever we are because the theres nowhere for us to go you. Know space among the twenty two million residents in beijing. In twenty sixteen the government initiated plans to make cities cleaner a more livable beijing set a target to reduce the population by nearly two Million People starting with the most vulnerable. And its the most vulnerable who generally lack access to clean water to as many as two point one billion people worldwide around. Two hundred and sixty three Million People have to walk at least thirty minutes every day just to access water at all. And one hundred fifty nine million get their water straight from lakes and rivers the worlds longest rivers in fact ensure the livelihood and survival of billions of people rivers like the nile for many in egypt its their only source of water. Made up till heidi has been rowing on the nile for as long as he can remember. When hes on the river the commotion of cairo seems far away. From. Close to twenty three Million People live in greater cairo egypts capital is expanding and so is its population by around two Million People a year. Almost the entire population of egypt lives close to the nile and shrinks from it to. The river is egypts lifeline. He says its a simple line from a moment in my life and i think in the whole egyptians life. And nothing. Was a river nile egypt disaster does a class for business thats a for me i was out man was always on every mile mile i would be just this. Egypt is mainly made up of barren wasteland sand and stones. The nile provides ninety five percent of the countrys water supply. Fields are irrigated with water from the nile. Made the rower is an agricultural consultant. Farmers share their worries with him. Many fear that this is exactly what could happen when the grand ethiopian dam up river is completed egypt would not have as much water for irrigation if you. Sold your water will get up and it will be if you will be affected for many years if you keep growing the land you wont have any problems if you stop have no water or. You would have a problem and the problem was they was. Here in the nile delta there wide canals and water seems plentiful. This is a fertile area but people dont appreciate how valuable Natural Resources are rubbish floats on the water. Although egypt is already dealing with water shortages farmers often use an ancient irrigation method. They completely flood their fields. Cranks up his water pump. Experts say this Old Fashioned method of irrigation wastes much too much water. The solution would be that farmers like should learn how to save water. Water shortages in the summer months are nothing new. At all in the ethiopian dam. The downs are already having an impact. On this canal always used to be full and i didnt need a pump. Clearly less water now. Kiersten eamonn is from the g. I. Z. The German Development agency is providing support to a farm school in the nile delta. These farmers dont just need to save water but must learn to grow more food with less of it. Egypts population is growing dramatically there are two million more mouths to feed every year even small changes can have major consequences. And i drop in water levels will have an impact whether its because of the dam population growth or Climate Change it will affect the soil and farmers will have to learn to deal with that in order to secure their future. As soon as ethiopia starts filling its new giant reservoir there will be less water for egypt. According to the agricultural consultant no one is quite sure how much less or for how long but one thing is certain there will be less more water. At the moment egypt imports around sixty percent of its foodstuffs. But the country cant really afford any more expensive imports. I think we need to get more more more of everything more house a more food more water. So less water was the same equation will be catastrophic. When our maid is rolling on the nile he is removed from the commotion in the hubbub of cairo. But as soon as hes back he is confronted with the fact that the nile egypts lifeline for all of history may soon windell to a shadow of its former self. And this mighty river is not just a lifeline for egypt either the white nile and blue nile joined in sudan and the nile continues its journey northward towards the mediterranean today this waterway provides around three hundred Million People in five Different Countries with water but by twenty thirty the regions population is forecast to reach three hundred ninety six million will the nile still be able to meet their water needs especially given that africas largest dam is currently being built in ethiopia. Beyond this simple string barrier lies one of the most sacred locations in ethiopia. Only Orthodox Christian males who are fasting and barefoot are allowed past the legendary source of the blue nile or as its called here is off limits for all others some one hundred kilometers downriver the precious waters flow into lake tana the largest lake in ethiopia. One of the many orthodox monasteries which dot this region is located on a small island in the middle of the lake every mariam. Belief in the power of the rivers waters draws pilgrims to debra mariam as well. Priest to met him was born and raised on the banks of the river. And means life to me not only because the water is holy he would but also because the church on this island gives. A church on the river. And people come here to be cured. Once upon a time the niles water even raised from the dead. A river so powerful people even ascribe miracles to it thirty kilometers south of lake tana the blue nile for africas second biggest the falls are themselves a miracle in ethiopia a country generally notorious for drought and hunger. Time appears to have stood still in the impoverished highlands. Further south the blue nile bends westward heading towards the Sudanese Border where it will be used to provide the country with electricity. Forty kilometers before the river reaches sudan a huge dam and hydraulic power station a taking shape on africas biggest construction site ten thousand workers toil here day and night the grand ethiopian renaissance dam was supposed to be completed last year but its behind show deal ethiopia intends using the blue niles physical power to end its dependence on International Development aid. Africans can make it. Very forceful africa has. A chance to develop so thats we have to. If we think then we can change our continent i think it is open to. Can see. That over eighteen hundred square kilometers the dams reservoir will cover an area three times the size of Lake Constance its power station will generate over six thousand megawatts that will supply all of the theo piers electricity needs with some left over for export to generate some income as well project manager semenya of the kelly says the dam is good for the soul of a country but the world underestimates. We know as a country poor and we dont want anyone to tell us what we know that. We are committed ourselves to. These eleven. Its an expensive way of tackling poverty especially without foreign funding ethiopias government is financing the mammoth five billion dollar down out of the countrys own pockets quite literally because there wasnt enough cash available in the treasury Civil Servants pay was withheld ostensibly on a voluntary basis. Public donations and lotteries also channeled money into the projects coffers. He sees all the projects and thats the benefits. And benefits. And we know this is a historic any better we have a stronger relationship to the downstream countries and they are a lot of brothers and sisters. Constructing this project aimed at a responsible and professional. That might well be but downstream sit down and egypt fearful that will restrict the niles flow for ethiopians though the new term is not only a symbol of National Rebirth its nothing short of a modern wonder of the world. And now its time for global ideas when we need people dedicated to protecting our planets wildlife this time were off to meet some pink dolphins. We joined a very special expedition in brazil. For the first time scientists are researching these mammals along with their habitats. Want to get back out. Over the years i should say to see. What if the. Research is of just cut just an amazon River Dolphin mother and her coffin a branch of the. National park the team says its all for their own good. Everyone is focused on this Worldwide Fund from the expedition is the first to land the animals which will be given a medical examination and fitted with g. P. S. Transmitters. We know very little about the pink River Dolphin species. We know a few things about their distribution but nothing at all about their numbers health their blood values parasites or if theyve been exposed to toxins from the school my school is. Just the animals are given authority checa. The unprecedented project is a cooperation between vets marine biologists fisherman and conservationists they have to work fast because the dolphins can only survive on loan for a short time no pink River Dolphin has never had an ultrasound scan before it presents a challenge even for the vet. And whilst the mother is undergoing tests have baby has already been way to measure. Out of sequence for the better. Part. After nearly an hour its time to return the animals to their not troll element and. I was told to believe. You would be ideal but it is. With the boys who says oh it was a complete success the team was exemplary. A few adjustments might have to be made but it was the first time and it was a mother and her cat which makes things more difficult but they stay calm. Everything worked out perfectly theyve already swum out but without a transmitter unfortunately. The next one wont get away. The fisherman come from the nearby village of sound. The people who live with and from the river that just as dependent on the mortars the dolphins. With hardly any Jobs Available in the heart of amazonia many leave the village and. Not everyone can work in the local shop. Some try their hand at Gold Prospecting often illegally. You know maybe somebody move into thats how i survived thats all ive got panning for gold but when the gold mines on land closed down things got bad here. Theres a bit of tourism but thats not enough for everyone. The only thing left for me to do is look for gold me. Its like heaps left by mining barges are everywhere even right next to a nature reserve. The barges pump gold bearing mud and gravel up from the river bed its collected in mounds where expensive by hand. The noise is deafening and there are hardly any Safety Measures in place. That it was is it dangerous. Look at this. Other bit of what happened while i was changing the suction pipe on the pump. Parts are all really heavy. And if you want focused on what youre doing. Its easy to have an accident. And then. Even more dangerous especially to the environment is the max youre used to extract the gold from the world to. The few changes in waste water eventually reaching humans and dolphins. The w w f team wants to find out how it affects the animals. Books from birth we know very little about the effects of mercury on animal organisms of course there are findings about the effects on people damage to wargames and the Central Nervous system. That we know next to. Nothing about its effects on wild animals. So were conducting a lot of tests in parallel. Music ultrasound and blood tests as well as tissue samples we want to find out how the toxin functions. You know. The increasing number of dams and hydroelectric plants up also a threat to the dolphins. Cause of the separation caused by the presence of power stations as the main problem they pose a barrier to Genetic Exchange a male and a female can breed and if theyre kept apart by. This time the team is determined to attach a g. P. S. Transmitter to a dolphin they can take hours to that one and then they still often manage to escape reception to record dolphins in colombia bolivia is also under way with other countries to follow the w w f hopes to build a database of Dolphin Health throughout all of our missoni and. Most of the animals have a relatively small and leave none weighs over seventy kilos and if you. Look at the breeding and heart rate constantly monitored this examination runs most musically from a professional inside half an hour the tests a complete and a g. P. S. Transmitter is attached to the dolphins dorsal fin which consists almost entirely of cartilage. What you do when most think the animals do feel what were doing to them but for the invasive interventions the biopsies and attaching the transmitter theyre given a local anesthetic in an instant called. The dolphin will be released back into the open water as quickly as possible. The w. W. Tapes the project will help to get the pink River Dolphin on to its list of threatened species to better protect them by your spare. It will be better to get. Back in the water the erstwhile captives buddies at home.
