waterfalls flowing water particles into the air b, trees and sweating out up to 1000 liters of water in a day or sea forest fires, evaporating large amounts of moisture tune in to get the answer. learn more about this phenomenon, a heavy, invisible river that flows through the sky starts march 23rd on d, w. a . hello, and welcome to a new edition of echo africa. water is a key resource without clean fricken water, which cannot survive. that's all of the topics coming up on the show. my name is

chris phillips. and hello for me from uganda. my name is sandra 3, no video. and i'm pleased to be with you for the next 26 minutes for do stay with us because we have amazing stories just for you. how under water i help with marine protection in cynical why tourism in finland is getting more sustainable and how it bikes, reducing traffic congestion gun that starting the shore in my neighboring country kenya is suffering from the was to drop in over 40 years. now from us of reporters on the bore holes have dried up when others have requested the government to provide them with water instead of subsidized fat laser. now we do ask how of formulas cor pink and what has been done to support them. let's take

a look. i do appreciate the scale of the drought in kenya. you only have to look at lake abala sat, which has shrunk like never before. almost 90 percent of it has dried up climate scientists sworn that the situation could get even worse. most climate models predictor that extreme where the events such as adults are likely to become more frequent and more severe. ah, lisa, that is mainly owing to, due to the global warming and climate change. these images from june 2019 show the lake a few weeks after the rainy season. an important habitat for animals like the

crowned crane and the hippo. the drought is a problem to, for people who live in the area. many farmers fear for their livelihood. the persistent heat wave, a scene fields across the country set ablaze. it's actually very, very, very bad. we have not had leads her fall most her several years. we have had several crop failures. ah glance are really not doing well. so we are really waiting for the reins. locals are desperate, extra prayers are offered, asking god to bless kenya with rain. the president and his wife are among the supplicants. we have prayed, and we can see the clouds are formed. and we know that the rains are common lake

abala such years, long decline is a home made problem. local conservation groups say a lot of soil has been carried into the lake following deforestation, and construction work. on top of that, people often draw ground water. there is no control or procedure that people there should follow to get their water getting mcqueen, but a much of it, it's vital that farmers use water in a more sustainable way. that's one of the goals of the nairobi, water fund. gutters and basins mean that water can be collected during the rainy season and then used to irrigate fields. when you are that or the water which come from the roof pop or may be from there, ran off our course of the water paths. that is one of the technologies. also, he showed the farmers how to pass the routes, especially the ones which are sloppy, and then sure that those terraces are artist applies to the nip,

the glass. you plug it off so that they can be able to capture all the water. which arrows the foil into that he was. one of the fund is already working with a network of nearly 16000 farmers. there harvesting enough water to irrigate almost 2000 acres of horticultural crops over a 3 month period. david comma is among the farmers benefiting from the project. the new methods mean he has enough water to irrigate his crops, even in times of throat, like no. for the then i robi water project, provided me with a water pen. mark, you might have all my about the godaddy, and i can irrigate by using gravity to come to the water and use a sprinkler. ben crown is foreign borders of river, but to come out uses of water upon a small reservoir to irrigate his fields and save valuable water. climate researchers say that sustainable farming techniques like these can help ease pressure on farmers even as we go into

a possible field rainy season, we are not likely to miss out on rainfall, especially in the month of april and may for the cost region. so we advice or what are some visual missions, including what this thing and what sustainable use of what the threat to the lake will only worsen if human activities don't change. but more sustainable water usage could help prevented from drying up. ah, we are staying with a topic of water, but heading now to the cost of cynical. the younger generation has a vested interest in environmental protection. it's obviously in the interest to look after the planet note was from docker. students are caring about ocean

pollution by rusty loss and the associated hardships. with the help of high tech here is b switch doing a bit. ha! now cindy gold coast is more than 700 kilometers long. here about 600000 people, only living from catching fish. but a lot of marine live here is under threat from over fishing to improve conservation, researchers need to find out more about the fish stocks. a new project at the deck, har, american university of science and technology aids to help. we come up with a team that would use underwater draws. these are draws, i would go under water just alike area drones. and they were equipped with cameras to be able to record things underneath the water. so we would take videos of fish

that were in the and in the lagoon as well as in dog c, as well as the floor. what are the different species there are underground under the water students, he developed the underwater drugs, an innovation that has made many tasks, much simpler, maritime conservationists used to have to catch the creatures 1st to study them. but the technology performs this job now. and then once we get this data, we would come out and then we would use, there was algorithm or software that allows us to classify the different fish that were there without having to thursday, where we had to take them out of the water at the simone nature reserve students conduct regular tests with the drugs. they want to use the data to help protect endangered species in a more targeted way. oh, and how about you? if you're also doing your best, tell us about it, visit our website center. so tweak, pastor, doing your bit,

we share your stories and made if these little packets might be handy, but they quickly land in the garbage bin and they don't roll in all web special, we charge the journey of such sashay from the origins that the raw materials made from to its end on the rubbish heap. we find out why the number of shades is growing and why they're so lucrative for businesses. and so disastrous for our planet. find out more d, w dot com slash plastic. in order to live green, we've got to keep a environment clean. could that be the key to happiness? well, according to the un sponsored wild happiness report, finland, ease the happiest country and it also cause high on rankings for sustainable

development. wal, i'd love to know more about how this all ties together. so let's get inspired with a troop to these novel european went to bundle land to find out how soft ability can be incorporated into the tourism sector. need to work with nature, not against me. that's something to learn from a young age here in finland far north lodge located not far from revenue. amy has belonged to his family for over 40 years. it was once they're much left holiday cottage. now they rented out the tourists who are looking for an authentic and sustainable lapland experience. in 1st of all, we are using sustainable electricity. we can decide what kind of an attitude we are using in freeland. now we're in orlando,

it's coming from the wind antenna. all you can see here, x rays, i got all kinds of materials samples. everything has been doing about sustainability and all activities we are offering. there is no more rush there to our guests can go. she animal footprints, snow, showing ice fishing. i swimming spectacular natural phenomena like the northern lights at the arctic circle, as well as virtually untouched, sparsely populated landscapes draw visitors from around the world to let land. the regions tourism industry registers up to $3000000.00 over night stays per year and knows that this hinges on keeping its beautiful environment intact. hearing for lunch, their biggest asset for the tourism is really their nature as well as they our

lifestyle that is very strongly rooted into peer and piecemeal a prestige environment. so that there isn't business is, are really interested in sustainability because they want to secure that long term business for themselves. ah, some go above and beyond like 2 or upper right. it beyond arctic during the high season in winter, they offer excursions to see the northern lights. but in the long days of summer, they plant new trees. sustainable tourism is growing in importance. globally, it had a volume of around a 180000000000 euros in 2019, according to the world tourism organization. and research is expect that to double by 2027. but even if tourist destinations themselves operate sustainably, the question remains how to visit is get there without harming the environment. there with them can actually have even positive impact to environment. for example

of you have gay says that's where the tourism has mandates to protect the environment by, by making it a national park for instance. but you are very right about that, that it's the aviation and it transport in general that really like god, puts it off from the balance this too much to be done to make tourism truly sustainable. but with their echo lodge, the burglary family is off to a good start. they're convinced there's no other alternative. wow, magnificent. i'd love to travel there one day. but it might just be too good for me . back to africa now where we're headed into the concrete jungle of our crop. everything crews and traffic congestion is full thin canyons to ditch the cause. i'm find new modes of transport and some of the solutions, a very effective indeed in gone us capital,

aka, getting from a to b can be a nightmare. it's normally hot in distances are far. and if you do drive or take public transport, you're stuck in traffic. rush hour can triple travel times. so canadians are increasingly switching to to real lawrence a. j is a pro cyclists and has been building his own e bikes for years, with a twist. ah, what is pushing on by case i use is accurate. lot of budgets. secondly, i by putting to possible this, then you have a stronger and is very strong on that is why i thought that was going on is i want to know young. i think it was like living right in this in that was if you do it. so want to create myself. stand

from then progressing to meters in like, or by the 26 year old is self taught. he watches rooted before we are almost every day and tinkers with his iep like lauren's orders, the remaining part through the internet. meanwhile, dealer russell men says sells a bikes from china, but those that are performance issues. the battery that came with it initially wearing stud rubble. so when it came within a shirt, this was will have been yellow or lot of complaint from customers, russell, believe skinny, and say increasingly keen on the bikes. and he sells around 8 units a month. but the price is steep. $300.00 to $1100.00 heroes for an e bike is a huge demand for the basic gun. the guns love you, bye thing is that go,

no body knows about you by lindsay by. this became probably about 34 years ago for lawrence to it's not just about the joy of writing, but also traveling cheaply and quickly, especially as fuel prices rise. his e bikes can cover up to 130 kilometers per charge. i wasn't because the distance out with are good to like very far so i thought i needed a mortal my dinner time went on, i told him all my situation and, and he said, well, you can do something out depending on the performance of the battery. a customized lawrence e by cost between $6860.00 euro's so far. lawrence has sold 7 of his e bikes, but he's looking to supercharged his iep. my dream with

traffic congestion is a growing problem in cities all over the world. what can we do to tackle it? okay, we could all try moving around a bit less, but sometimes you have to move. we all have places we need to get to. well, we can learn a lot from the animal kingdom. scientists often use animal behavior as a reference when it comes to new development in medicine or biotechnology. ant movement, for example, could provide a blueprint for more efficient traffic management. bad traffic, bad vibes. and highways are also super busy, but clearly run a lot more smoothly. in the human world, congestion on the roads is a normal part of life. we even keep track of record breaking jams. when hurricane

rita hit the southern united states in september 2005, 2 and a half 1000000 people fled houston or tried to the resulting tailback on interstate $45.00, heading inland towards dallas, reached a length of 160 kilometers for 48 hours in the run up to the 2014 world cup and brazil, the roads in and around sal. paolo were gridlocked, 340 kilometers of stationary traffic, almost equivalent to the distance from sao paolo to rio. moscow, november 2012. the notorious russian winter paralyzed much of the biggest country on the planet. for 3 days and 3 nights, snowstorms blocked the highway between saint petersburg and the capital. but how do traffic jams actually come about it? the main reason is that you do not have enough capacity. um,

of course there are other reasons um, but these reasons, reasons are not that they do not happen that often. um, dumb people sometimes make driving mistakes. of course, for instance, they do not pay enough attention and then they have to break heart rate works heavy weather conditions. but most of them are due to the same time the same needs in the same direction. but the world runs differently when the principal is one for all and all for one not hardly applies to motorists on the road. everyone's

thinking, what's the quickest way of getting to my destination? individuals focus on themselves and don't care about the others of to the drivers have a lot to learn from aunts with lifetime. i know donald hall faithfulness. i was a driver and wrote her name called written it listing, and it is a thing which hinder of the old system to be effective. so this would be a difference in the bed. the good is both maxima, that is, if you, yes it the user optimum and the system optimum. and normally the dog, the ones who have for him. so the best situation, so it is the user optimal, but it's not for the system the best way. so and cooperate and have a common goal. humans on the road, do 2 in

a way they each want to get from 8 should be. but the lack of cooperation results and countless people wasting vast amounts of time in traffic jams. how much time precisely, telemetry experts have the figures take. for example, germany's biggest city think palm has made on this kind of from statistics and they they have a number to days. how much more time have you invest them in on your daily commute and from pearl in this number? it's about 30 percent in other cities, it's much, much worse. 3rd spot goes to bogota. residents of the colombian capital spend an average of 230 hours a year going nowhere fast. that's almost 10 full days. the frustration can sometimes boil over ah, number 2, bengal in 2019 drivers in the indian mega city spent an average of

243 hours stuck in traffic. ah, but when it comes to road leading congestion look no further then maneuver. researchers worked out that in 2019 rude users in the capital of the philippines. last 257 hours of their lives to the daily commute to many self absorb drivers with big egos crammed into narrow spaces. anti waste by contrast are always busy, but never congested. how did they manage that? can communicate by a sense, they have plans to produce them. various pheromones convey information such as danger, food all this way, and think it's long for that community that the system up to them. they want to have a working flow which is not stopped by individuals

so we can learn from the end. but i don't think this one can teach the people to behave like depend on a communal efforts and adapt as conditions change. humans communicate not so much with each other as against each other. and while costing us precious time that comes at a financial cost as well, if it didn't thank you. so we have the highway and you say you have a 4 kilometer jen to name for 3 hours, then you can drive only 10 instead of 80. then you can calculate what is the last time on the drive and to end up being 510-0000 euro lunch. and i calculated gemini, for example, if you come up with 862100 1000000000,

you'll. ready for year we take the average 80000000000 euro we lost just by standing still. and jeff, so you don't only lose time. ah, so what's left to the lessons? can we learn from the internet with america? then we can copy the behavior of us and. ready this is the hope that then at the end, we will have a working traffic system which has a much larger capacity we have today. oh, insights from ants might soon be translated into better traffic routing and better attitudes. it's ultimately up to us. we need less ego and more consideration for others. it's better to cruise at a moderate speed, for example, than speed and slam on the breaks. perhaps then we'll be able to save ourselves

a lot more time and money and avoid scenes like this. what an inspiring idea i'm afraid that's all we have time for today. thanks lee. joining us here on equal africa and to be sure to come back again next week until then it's good bye for me. chris elapse looking forward to seeing you again next time please. and that closely you of you as, as well. in the meantime, as you know, you can always check in with us on all of our social media platforms will always waiting to hear from you. so it is a good bye. i am sandra tina with you take care ah, a, a,
