i come to take talk in about hackers and paralyzing the tire societies. computers that are some are you and governments that go crazy for your data. we explain how these technologies work, how they can go for it. but how they can also go terribly, watch it now on you to a most the fours are now feeling the effect of climate change. there is forest fires, drought, or whether in africa or europe everywhere is hot in op,

which means our weekly environment show is no more important than ever. welcome to echo africa from ogen state nigeria. i am chris phillips. are welcome from me too. i am sandra t. nobody and i'm here in counselor, uganda. well, drought and how people cope. we lead ease. only one aspect. we're looking out in this fixture also on the program. reviving an ancient irrigation method, him to museum. we show you how to better maintain the increasing number of wind turbines in europe's waters. and saving the rough, how namibia is protecting the walls, the tallest land annoying to day, we start our show in europe where persistently hot temperatures have been causing major problems, including forest fires, crew failure and heat related to the world wildlife fund that sees eats

calculations shown by 2050, the number of people facing extreme water shortages in europe will have risen by 50 percent. farmers are especially feeling it right now. most funding areas are at less than half their regular water capacities. so do we really have options for countering the water shortage? this plant is still something of a rarity on german farms. the chick pay, it's more commonly cultivated in the dryer regions of southern early. the scientists are planted de la creme hair on a small organic farm to test it under these conditions. chick piece, grow well and the chalky sandy loam soil found me or come out a region in north eastern germany with dumb circus in this year. we had severe drought once again on the crop developed really well and figured out here in

this location. it demonstrated a high tolerance for drought and, and that will be very important in the future with hair in one of the countries driest regions. the research as a testing 5 different types of chick pay and they're also collaborating with local organic farmers. the most productive chick plants could be staring come up to now chick peas, have mainly been imported, and demand for them is rising. and guns and shade enough. one very decisive factor will be the extent to which we managed to create landscapes that retain water effectively in particularly in agriculture limbed or don. it's not enough to just switch to new cry like trivia switched. it's as it somebody kisha, opposite water shortages are not just affecting farming. ground water levels have fallen throughout germany. the amount of water currently lacking as a whole year's worth of rain and say climate researchers from come finish. now

there's little coming from a book to replenish the large amounts of water evaporating from rivers, lakes and marshland yacht with less rainfall. the higher temperatures and more of operation of idols means that we're facing critical situation law morph regarding kritisha. the thoughts june are common saving water would be one of the 1st steps to take but people are still filling their private pools or watering their gardens liberally. further depleting, ground water resources, stroudsburg, etna, a suburb of berlin, where a lot of new houses have pools, is one of the few municipalities in the region to take action. from now onwards, anyone using more than the average of a 105 cubic meters per day, we'll have to pay a fine add new construction has been put on hold. but water shortages are probably her to stay. climate researchers estimate that the state of brandenburg will have to make due with 20 percent less water by 2045. there's

already a low water management plan, but that won't be sufficient. d, a written tampa to one period because of water loss due to rising temperatures and subsequent evaporation of where you cited that we will take legal is that not to establish an official war to reserve far less on bracelets at apple. even the plan is to set aside 20 percent of available water as a precaution, meaning the local war works and citizens would have less war 2 at their disposal. the german capital has its own experience of managing limited amounts of water balance. drinking water supplies come from ground water, which is largely fed by nearby lakes and rivers. but it's not enough. the city has been boosting ground water levels for a long time. now pre purified water from 2 rivers is pumped into pons, which then seeps down into the ground water that provides around 10 percent more

drinking water. and that's all recycle t. i'm shoes on a warm summer's day. we use about 750000 cubic meters a day. and at the same time we put the same amount of waste water back into the system. possibly in the same way. you can see that more or less balance is out balance strength or graphy with that kind of circular usage is more than the quantity should be adequate in dry years to google yard high. but if levels continue to drop, then there may be less water in circulation. the water company's calling on the city to provide more spaces that are able to absorb rain water rather than the ever more impermeable surfaces. keeping water in the soil, that's an important aspect of organic farming yoke. usta had a good lupin harvest this year. it's a crop that can cope with modest rainfall. preparation of the soil also plays an important role after the harvest. it's only lightly tailed and then come when

you're a spread on top to create humans that you love ya are tired. we have a certain amount of water available for the year away. all the work we do on the fields has to be adapted to that. donna hoseley, so we try to work the sol as lightly as possible or to look slots. so we don't air right too much soil wouldn't like lift because then the water simply evaporates us to instead the cultivation of these protein richly games is profitable because the crop can be turned into flour or used in vehicle products. your usa is looking for other alternatives for the future. so perhaps along with white lupins chick peas will soon be harvested here too. well, thing on the subject of waters castillo, when i'll head to, to noisier in northern africa. here farmers is up to 80 percent or, or what are used in the country. so they really need to change their behavior

moving forward. sometimes it is enough to take advantage of the old traditions. so take a look at the switch, doing gibbons, blah. ah, olive trees are hardy plans that you well and arid regions up to a point in the past. there used to be adequate rainfall here in northern tunisia, but due to climate change, it's become a lot dryer. and now farmer mohammed ben is maya transports water to the orchards from a well that is far away water that's becoming increasingly scarce. so he's filling allah's clay pots that he's buried in the ground. the un glazed vessels have porous walls can are quite large. if the soil dries out the pots act as a reserve to keep the roots well supplied, the trees just get the right amount of water pyramid. this methods better than

direct watering, because when you pull water on to the ground, the water around the tree about her eggs and better still, this ancient method does the job using around to 60 percent less water chemist. an olive tree expert, p monkwood. lottie is carrying out chests on trees. here in venice, my as orchard, locally my unit jamita. when the weather is humid or when it rains up by, you know, water seats out of the vessels look lost can get luscious high when it's dry and the trees need water there has the roots can absorb directly from the supply in the buried part as well. the bet i seal the low other a patio did elijah and there is another advantage. these trees produce around 20 percent more olives. despite less water being used, the olla method dispenses water much more efficiently.

and tell about you, if you are also doing your bits, tell us about is this is l websites both send us the tweet hash tag doing jo, base? ah, we share your story, ah, the rings, the re montes are african largest mountain range, also known as the mountains of the moon. they struggled the body to uganda and the democratic republic of congo. they are a popular destination for climbers and wildlife tourism. absolutely, and it's one of the most beautiful places in your country, sandra, but sadly, here to climate change is having an impact. and the famed glazier is our melted forest, could help to slow the process in the area. one man in uganda has used his own many to do just that. here is our echo hero of the week. may just chorus.

it's the sweet reward for nurturing and protecting the small forest and allowing it to flourish. i've got a pattern with animals and birds and the ecosystem. we must see it amazing cause the tranquillity you can have your peace of mind here. you can meditate. i'm lake that noise. in the city somebody, janice family once grew crops on this land, but they, kids ago the former hotel manager, dedicated 5 hickory as of it's solely to trees. i've been to europe and out of these places and whatnot, says land geneva, zurich, in perry. and all these places is people have what the green and trees and what if it is in the cities

and they don't see why we can't to at least did some of those things and do it the same, you know, replicate them. we know our cities the small wooded area is close to the center of foot or 2 in western uganda, often referred to as they get in city. foot butcher is a getaway to numerous national parks and safaris, but its popularity is both a blessing. and because this city of 50000 inhabitants is expanding and that has taken a toy on the local nature we used have trees in town and we think that those trees are no longer there. the news have wetlands co solved by louis. that's not the case. here where this is a wiring trend for the environmentalist foot pottery,

surrounded by in number of precarious nature sites, including charlie national buck with its population of wild chimpanzees. and queen elizabeth national park on 2 great herds of elephants. and on the horizon, the reins or re mountains africa's 3rd largest mountain range here just as elsewhere around the globe, the glassy as at 5000 meters, a melting due to human given global warming. the fresh water that flows through the re verify what portal also comes from here. it's another part of the fragile ecosystem that more general wants to see protected mac river new. literally no, he's passes badly, resorted mountains and intensely care. but as the assembly cutover and it goes through make out but comes out as the ad,

but to nail and jane is the other. the other you are the cougar when me and off it goes to says gonna. so leslie linkage, rarely the eco activist is so passionate about the environment is of unwilling to fight for it. in court by jana celebrated success at the foot caught house after swing, a road construction company for polluting the air. and when the case that's when the whole country knew that even that the, that i'd call certain names because it's whereby every citizen dated to clean and his environment from vain. now, these fellows cannot do a rod in any, in, in a community without spring with the water mo, war to pumps, whatever it is on the road. so that the, the madam,

because wait and doesn't have to meet the, let dest. but what will happen to boy generously to paradise when he's no longer around? he has rejected an offer of millions from a tourist group. trustees, i to ensure that the forest remains as it ease even after his death when he passed away. your future. am people coming after me? don't destroy what have much had for all these years. oh, why to my grandmother who came here 1930 lift that legacy may mother followed it. i'll die neat and i won't even new future generation to do this. im over the last 3 decades, uganda has lost more than half of its natural forests to encroachment according to

the conservationist. that alone should be enough incentive for the next generations to follow his example. now let's move to europe, the governments. they are searching for new sources of energy and not just because of the energy crisis caused by war in ukraine. so they switched to renewables. more and more big wind farms are been planned and constructed in the north sea. the problem is they also need regular maintenance site is from the u. k. one to help facilitate that task in the future. offshore wind turbines. they produce a lot of electricity, but maintaining them is complex and costly. this tank at a scottish university can simulate conditions at see the scientists here, a testing, a remotely operated vehicle, or r o v. designed to make the upkeep of offshore wind farms safer and cheaper. if

successful, the device could revolutionize the offshore wind industry. you have to imagine that in 1015 years time, they'll be unheard of windfalls, which means thousands of wind turbines all across the coast of the u. k. the also laughs or may be new i door gen technologies being developed and all of this will need to be maintained, inspected and serviced otherwise with using loss. hip we have lots of crew. this is not scalable. there are currently around $5500.00 offshore wind turbines. in europe alone, like britain, many countries on the north and baltic seas want to expand their offshore production in the coming years. wind turbines becoming bigger and bigger. most the heavy steel structures anchored to the sea bed in deep water, far off the coast. that puts them under

a lot of strain. so the supports must be checked regularly for signs of damage. a typical mission would be to send the vehicle down. typically in the nor see 4050 meters rarely more, but in other parts of the world, you're talking of hundreds of letters. i needed to encrypt the system with some autonomy. so the system of a set of cameras here are so in our sister, acoustic system to image lights and or what the gum most maintenance work on wind turbines is done by industrial divers. but it's tough work and very expensive, not to mention extremely dangerous. in future, many task could be performed by our own. these typically you would have corrosion on the, on the system. if i thought to turn evolve, you might have to correct the cable. you might have to change that, i know clean the surface if is too much by falling,

et cetera. so there's lots of lots of use cases for now, the robot is still connected to land by cable. later, it will be able to operate fully autonomously in the sea or if necessary, be controlled by a drone pilot. the system will work for inspection of anything that you can find under the water for pipelines, for c bed and for, for shipwrecks, anything that you would like to explore? anything that you would like to 3 d model test is still being conducted in the lab for now. but last spring, the underwater drone had its 1st field deployment, at an offshore wind farm of the northeast of england. it successfully recorded videos that allowed researches to assess the exterior condition, a foundation, some tables we end up are showing the media for more than 5 years. now, giraffes are all the red list of fishes threatened with extinction. once common

across the continent, there are less than $100000.00 of them, less war. what a shame. but there is hope. we went to the country in a very soft west of africa, where santas from an inch or have been studying the rough population very closely. and they now see there are reasons to be cautiously optimistic. most people are familiar with giraffes, but far less is known about them than many realize what certain is that they are the world's tallest land, animals which enables them to reach lees high on trees in the african savannah. what's less anon is that you rubs are incredibly fast in short, best they can run up to 60 kilometers in our beyond that they are still many unanswered questions about them. what are the different species? how many giraffes currently leave in the wild? in namibia biology esc, lackland mac features enjoyed the michelle more one to learn more,

the photograph every year of the sea, so they can be identified later at a female, right? 8573 of so visual studies like these have concluded that they are currently only $117000.00 euros in africa. by comparison, we are nearly 4 times as many elephants. if you think about sammy locker and african elephant, there are no, you know, i ran at 400000 mark, i believe individual. so if you think that compared to $170000.00 individuals and it's pretty incredible for such a, a large, a browser spaces that is kind of one of the, the most iconic spaces in africa. really. there's been very little work done on them. i suppose the priority in the past has been some of the more sexier species like elephant and lion and draft of sort of gone under the radar. and i think because they are quite wide spread throughout africa, you feel like you see them everywhere. but that is deceptive. climate change in

humans clearing land for settlements in agriculture has led to a substantial loss of happy 10th 40 wraps. in the past 30 years, the population of these graceful animals, his sank by about a 3rd waste in rivers, also threatened their drinking water. when tories numbers dropped you to the cove pandemic, these guys started picking up the trash instead, which will benefit the drug in the long tim, protecting these animals has a long history in the media. if i can tell you more little bit about the bushman, the they were not killing drop it or even putting their handing activities. they were not targeted to ross because they thought it was the tallest anymore. and the realize that killing a giraffe, you are cutting communication between yourself and the other system. this was once considered a 2nd sport, 3000 year old cave drawings prove how important europe's where to the people

leaving here. they were regarded as bring us off life. we believe in the euro, that the mad extra extent they are neg, touch their clout and make it dream. so good. rain is a good i have year for them. wild you wraps in western and central africa. i still under threat their numbers in namibia, in its neighboring countries, are actually increasing. rising from 30000 to almost 50000. that's largely because they are better protected here in national parks. this is done vision game reserve located nina. medias capitol hill dog. today, kids from the children's home are hoping to get the 1st clips of a real g rough edge, rough skull like this one is very heavy. the animal sometimes use the borne your projections, cold or seconds in combat with other animals or like all standing next to

a lab. bon, give the kids an interesting sense of proportion or i'm, i had a leg dress, i love the colors and i lay it looked like i am dull, very strong. so draft kicks are very powerful. that's how they defend themselves from treated us. example lion. so they can kick a lion. the children won't have an easy time sporting the animals to day g raps. i shy. miss turtle on the other hand, wasn't too hard to catch. you don't put your fingers next to them out. it's hoped that if children learn about the animals in the region, there will be more likely to fight to protect them in the future and doesn't get a group of kids. and when they see animals, for example, giraffe, don't tell you that elephant or defeat. oh, i'd be standard, tell you it's a horse. and that's surprising because we have so many wildlife in the country.

that's why we think that if they're needing the moment, litigation, and that this program is actually making a change in difficult life. giraffes prefer leaves from bushes in trees or long river courses. akasha trees are among their favorites. biologist, lackland mac feature, see that as a result. they don't compete with lifestyle for food, making conflicts with farmers re sofa. the scientists have counted 450 giraffes here in northern namibia, and they are doing all they can to make sure these elegant creatures survive. wall, what beautiful creatures and what an amazing planet we have. certainly one was protected. well, i hope you enjoyed the show as much as i did. sadly, it's once again time to say good bye. from ogen state nigeria. see you next week. if you wanted to tell us your own ideas or simply find out more dis and as an

e mail or full arson, all our social media platforms there, you'll find plenty of more stories and information. so it is a good buy for me here in camp le, uganda. do have yourself a wonderful week. i ah, a, a a, with

a j. a journey across the entire continent with a variety of cars. so what on this,

so the focus, the mover shake is visionaries and made does when body the meaning of modern africa is as an egg on d, w. mm hm. we're interested in global economy ah, our portfolio d w business. beyond here, the closer look at the project, our mission. to analyze the fight for market dominance. east versus west. give that head with the w business beyond ah, some people don't care about me because they don't see my beauty. some people don't care about me because they think i have nothing to give but
