the others soon. to be. discovered. documentary. of the. did you know was that more than 2 sides of the is covered by water so you can see much of what a huge role this plays in meant taming the ecological health of a planet welcome to iraq an african environmental magazine. i am son does he know
1:31 pm
he'll coming to you from kampala here in uganda and a big hello to my fellow present at and t. in nigeria hello everyone and hello sandra you are so right about our waters in fact you could go so far as to say about the future of our planet may depend on the conditions of our oceans lakes and rivers we'll have more on that in the coming reports but 1st a brief look at what's lined up today in our program. sessions has a rescue plan it's called still a way as well take a look at how that works. danes the government's all part on climate change has just presented its report on the condition of our oceans we'll see what he said and in germany and other parts of europe you can go kayaking for free as long as you collect trash along the way. first to the seychelles where environmentalists are working to protect coral reefs. these frogs ecosystems are
1:32 pm
among the most specially rich bio tubes on earth and the island nation relies on them for its very survival and emissions of launching 2014 aims to support a healthy ocean and implement climate change strategies and to promote the stable blue economy and the region depends on winning $115.00 islands that simple a goal is truly unique a marine ecosystem. but. this issue's is a tropical paradise the iraqi pillar who covers around 455 square kilometers of land. but more than 1300000 square kilometers of sea. sand on our american resources for everything whether its economy activities or for tourism and fisheries we don't have anything without that. many tourists come to
1:33 pm
visit the archipelago for the spectacular. so i realize that he wasn't forced to kill quite a survey old fellow and growing up and understanding the relation that the say show what people have with the ocean with the assists in the how much we rely on. a submarine scientist she's concerned about the growing pressure steam. experts go on regular days to assist the conditions fishing environmental pollution and to resume put strain on the seashells unique underwater world. the coral reefs are suffering the effects of climate change because they're very sensitive to changes in water temperature. they provide a home for a whole host of the marine life 'd from c. snails to sharks so without them biodiversity sofos reefs near the coast are
1:34 pm
especially vulnerable and they're the 1st ones to die. there has been a rise in ocean temperature and this has an impact on your corals then this leads to coral bleaching and then you move the coral and then you end up with that corals by the late 1990 s. most part of the reason the shallow waters had. why quarrels and once they dead they are usually taken over by. the resources and the activities that you carry out. that. now the government recently agreed to protect nearly a 100 of the country's marine mortons within the next 2 years as part of an initiative called the seashells on the incident. occurring or to
1:35 pm
some of the of the underwater ecosystem. we carry out an activity with intent. on. ensure that the management of there is effective in partnership with the nature conservancy ngo. regional climate hoping to understand exactly what's happening to the lives. regenerating. because the waves and currents and constantly moving this kind of coral around making need for new ones to sit. on. you can see the changes where you have this very long period of time where the temperature is really high in the corals recall so this has a huge impact on your marriage. we have started
1:36 pm
a coral reef project looking at other ways to try and restore coral reefs using the corals. and growing corals and putting them on the reef. together with the fisheries in terms of confines the country wants to find ways for everyone to use the ceases to live leak even after the protection of. the marine especially plant is the fast of this kind in the indian ocean very important that we constantly have this good healthy coral i want everything that i do or should make a difference and if you have any i think it's a really wonderful feeling knowing that whatever information you bring that it's going to point you to the way we do conservation that's going to have a positive in. my requests away from the face. of the project transit least until
1:37 pm
2020 by which time the fos long term protection plan should be the eco system in the sea shows is counting on. what a beautiful place let's hope it stays that way about the united nations' intergovernmental panel on climate change recently published its assessment on the state of our oceans and it wasn't good news the same process that's happening on land is also happening on the sea yes sagal you're right and we are being too careless with our quartic eco systems the increased levels of a border being absorbed by the water bodies how slow to acidification coastal areas are being polluted or eroded marine life is disappearing in a moment was picked to an expert in nigeria but for now here are a few raw facts in our new segment ecologic oh.
1:38 pm
the ocean is a place of many wonders. but now it's garbage dump $8000000.00 tons of plastic land in our oceans each year. about one garbage truck per minute. that's not only harmful to all sea life but also to human beings. climate killer carbon dioxide around 30 percent of greenhouse gases from human activities are absorbed by the ocean that's roughly $1000000.00 tons per hour. that helps to reduce the greenhouse effect. but the more c o 2 the oceans and seas absorb the more acidic they become 40 percent of all coral reefs have perished in the last 3 decades. the oceans are getting warmer
1:39 pm
sea levels are rising. between 201720188 rose by 3.7 millimeters it's the highest sea level rise in a single year and it's already enough to flood small island nations. it's pretty shocking isn't it the oceans have huge potential to adapt to change and even to compensate for it but that can only walk if we humans also play a part my colleague n.t. paid a visit to the nigerian institute for oceanography and my results in the while his spoke to dr rice in a follow on that is to collect data and mix recommendations to the government on how best to protect the sea or off the coast caused dr follows so had some interesting things to say take a listen to. the. doctor follows thank you so much for speaking with us on the who are now we've just heard
1:40 pm
of. or will speak about those as you walk with i don't see holes in the documentary so can you tell us what exactly is the state of the ocean. around the world become now confident that ocean. ocean will last. when you take a seat cruise at the national empowerment for example a fisherman you will catch tons of plastics and very little fish the fish gets in bed because they are in just saying plastics and they have a stomach full of plastics what is the situation like that margie i mean we don't do the clean up the plus you know the polluters should pay they should encourage people to come out for beach cleanups there are also domestic waste in the oceans there are several things the biodiversity is depleting the monger by the fish and
1:41 pm
is deeply tied and the ocean is not so good do you think the government can do anything to make some countries are bombed or states yes our governments can help by. gets in the salient groups of people to create awareness of the bum agent effects of single use plastics for example cops you know plastic cards strolls plastic bottles all those things should not be you wish to go back to what we used to be you know in the fifty's whereby we use a vegetative league to say food we use cotton box food shop most things we ought to be doing to save the environment let's the last exam because a little bit of the question of overfishing and africom on the course of the stories in the mesh size for fishing you know. is smaller than the splits
1:42 pm
fight mr eyes because if you mess 5 smaller than it is that you take on bald more fish is done just what you targeted the federal government can help by have been you know money train systems all over the coastline because we got our fish resources with the people who would do more to come from and you do constantly. this forced the embargo nigeria without talking about the oil industry and its impact on the well we have oil fields and this oil fields affects the fish resources because the juveniles cannot breathe when there is oil of the focus of the water for the juvenile guy and then we have the whole fish talk to a level for human consumption this week in the u.n. the u.n. talk about climate change you know do you think some of these marches need to be looked at more more deeply than. for us because we have to save our next generation these are the resources we have to live for them so we have to look
1:43 pm
critically at the climate change issues at pollution that's a single use plastic you know being dumped in the house when you pull look you must be a function you know when we put some of this fence in place to keep on vironment safe for the next 2 years thank you very much both of you. so know we a bit wise about the state of the world's oceans but what about the locks on the rivers which make up a significant part of the water system in many countries i hear things aren't much better sandra not if you talk to the people at the danish initiative group kayak but they are not just complaining about the state of you of the rivers they are taking action they've come up with a pretty cool idea as you'll see in this week's doing your bit.
1:44 pm
moving far too much waste ends up in rivers and lakes especially in cities that bother to b.s.d. about london and from denmark so much that in 2017 he launched an initiative called green kayak travelers can use boats for free in return for collecting any trash they find in the water. cannons recorders. it ends this for us since small bits of plastics and. green kayak now has support in 5 countries including germany after reserving online about a bucket and trash grabbers can be picked up at the dock of a cooperating boat rental a few enjoyable hours on the water that benefit the environment too and others are also getting on board to mention people are pretty conscientious these days almost everyone who rents a canoe kayak or paddle boat picks up whatever trash they find along the way and in
1:45 pm
that green kayak volunteers have collected over $21.00 tons of waste so far and as word spread via social media the amount is sure to grow. and how about you if you're also doing your bit tell us about it visit our website or send us a tweet. doing your bit. we share your story. and that will be a good idea for law going here in lagos we're going to stick with the subject of rivers and visit one of germany's biggest waterways now the right even major rivers are feeling the heat as climate change gathers pace right and what we tend to forget is that a river system like that one provided on the source of water for people and not so forth thousands of the is here to the eco system is fragile and needs protecting so
1:46 pm
our water treatment plant on the rhine purifies millions of littles of water every year. the rhine is one of the most important rivers in europe. it's 1200 kilometers long and over half of it flows through germany seanie because it is it's also. a busy transport. industry lines its banks and much of its waste water is discharged into the river if it isn't cleaned 1st the water is contaminated and can't be used for anything else here before the wind sampling points close to the river bank the water is extracted from the river as it flows by and then to transport by each with a diameter over a meter directed to the water works right there the water is intensively cleaned before being directed back into groundwater reserves via these shafts the water treatment plant south of frankfurt is the only one in germany dedicated to
1:47 pm
processing river water. the infiltration process taking place in these tanks has a number of advantages. historically very. well historically surface water hasn't been used for drinking water in germany mainly because the potential for a disaster on the rhine is unavoidable so we couldn't guarantee supplies around the clock and there are also hygiene reasons the infiltration process filters bacteria from the water i'm reducing if not actually completely removing the risk of contamination in the summer time the water in the rhine can be as warm as 28 degrees the infiltration ensures a temperature balance so the top priority is maintaining groundwater levels guaranteeing a clean water reservoir even in the event of extended drought $43000000.00 cubic metres of water per year a processed here at the main treatment facility in bieber's heim the process is
1:48 pm
managed to monitored any control center or mushrooms industries and you need to bear in mind that this solution is only possible thanks to local geological conditions and with what we have here as a vast natural aquifer you don't get them everywhere. across eastern germany for example there aren't any natural reservoirs. so this sort of solution wouldn't work there for geological reasons. water from the rhine flows into these basins and these purified using especially develop process. the response once the water has been mechanically purified in the untreated water pump station the next step is flocculation that's part of the chemical purification process a flocculation agent is added so that flocke forms which is a nationally soluble that has turned into sediment and floats to the top the next step is to filter off the purified water. the facility was built 30 years ago
1:49 pm
at the time it was state of the art today it's been extended to be able to cope with the increasing. contaminants in the rhine. the water is examined for bacteria heavy metals and pesticides here in the abort in germany drinking irrigation water must satisfy stringent quality standards that have based on specific micro biological parameters the facility also provides clean water to farmers such as hands you wouldn't fish if it irrigation. the soil in the region suffers badly during heat waves lately local farmers have needed to irrigate much more than usual to secure their harvest. around 12 percent of the water purified in the facility is a market for farmers it's going to be sure it's essential we grow onions
1:50 pm
strawberries in the step is flocculation but it's part of the chemical purification process a flocculation agent is added so that flock for it's almost as clean as drinking water and that means we can sell our strawberries directly but i can wholeheartedly vouch for our produce. farmers pay between $30.50 per cubic meter for the irrigation water drinking water would cost $10.00 times as much says hans you can fish out against a backdrop of climate change clean water has grown more important than ever for the region. back to africa here in uganda but also in terms of kenya fish stocks in like victoria are being depleted while this one is spotted to them ours is over exploitation of natural resources a project with partners from 7 countries in europe and africa so in forces to tackle some of these problems we went to the gun inside of left with toria to meet
1:51 pm
up with a team from the university of cars in germany the scientists are here told what their goal is to boast fish stocks and also show the local communities how to preserve the environment. b.b. muhammad has been fishing off their gun and shows of little tola for more than 25 years. but. we no longer catch fish like we used to do it had a big economic impact on us. right now you can sit traps and come up empty or give just one catch a week in the old days we would get a good catch every day but. the main cause for the depletion of stocks is overfishing pollution from industrial activity is another problem these issues have made it harder to meet the rising
1:52 pm
demand for fish. this has prompted some ugandans to set up fish farms. one of the biggest challenges is the lack of clean fresh water. you are now a fish from outside the capital kampala. to fish farming you have to get flushing your ponds all the time so you can imagine the amount of money that was spent just to make sure that we had water running into the different points every 10000. she's taking part in a union funded project called v h one she does fish from us are learning about a new technology. it was developed by a team of european and african scientists the project is led by professor john from the university of khan's way in germany the team has come up with a new system green use west water order to cut costs while boosting efficiency.
1:53 pm
one develop a system for the market it's called research aquaculture so this is a makes use of 100 percent water reuse water is circulation so it's mentally very friendly because there's no water going through and there's no nothing spoiling the environment and we make use of renewable energy in order to reduce the c o 2 footprint. in the tunnel on the cañon side of the lake chapala product is already in place the water is filtered using what's known as membrane bioreactor technology. over in uganda has been using recycled water for the last 18 months the used water is pumped into our time from there it flows into this busines which contains toms and sun that help clean the water.
1:54 pm
wants to use recycled water to have big points too. so we already have a system and it has proved to be very efficient for us using the same water would maintain the same temperatures because that's also very crucial when you're watching exit to the into her chair so for the points that still work in progress for us to see how it would be able to integrate it. this is just like more far must recycle water ideally using renewable energy the professor and his team have been working on this project for the last 3 years so far their work has brought them to uganda kenya and tanzania. we want to train we want to show people and we want to see how everything develops in the future and finally very very important is we need to add that this solution for the local market so at the moment we've brought
1:55 pm
a lot of ideas from europe and now we need the feedback of the local people to give us a guidance in future how can we develop a low cost system one of the ways they're hoping to achieve that is by promoting exchange between scientists and from us the established best practices that boost fish stocks and protect the environment. so what we us would see a dramatic decline in sea life oceans on waterways full of plastic an industrial waste surely it's time for all of us to do our bit and hopefully you know how you can do that you've been watching a special edition of. offical on aquatic eco systems it's time for me to say goodbye from kampala here in uganda. and goodbye from me in lagos nigeria you can find the show on further information on our website and social media platforms and remember our oceans and waterways are just as important for the planet as the lad
1:56 pm
see you next week by.
