in the phone system blends and there's no need to buy tickets the festival display . but that your up to date of next out environments magazine splendid 8, looks at how single parcel it's worth of crisis. thanks for watching the

no joke, but this face is a serious issue with what's what's a, here's change the cause of the war. started fights with neighboring countries and dominates the cities political agenda. and yet this country is a role model. single, forgot it, right? as simple as that, this is how sing apple is transforming. and so from one of the most what the stress countries in the world to self sufficiency from what rex to which is the a welcome to singapore, the vibrant multicultural city state right on the equator. densely populated around 6000000 people live on this tiny island. it's an international helpful trade in finance. it's clean, safe, more than wealthy green. basically, it has a lot of everything you'd want this just that one think cigna pool has no natural,

fresh water resources. and the way its economy and population are growing. total water demand could almost double by 2060, but the thing up was on it. none of what they've done is magic. that's peter. like he's an award winning what the expert he put the single pull success down to what he calls the soft pass approach to their problems. so the solid path for water is in contrast to what we have done over the last century and more, more than a century. but the hard path to build hard infrastructure to take more and more water out of nature, to ignore the consequences of our water policies for nature, to build narrow institutions and the soft path tries to turn that around and say, let's use water efficiently and carefully. let's stop wasting water. let's look at new sources of supply. to understand how single pole can pull this off, you 1st need to understand where that coming from. the single floor of

what the story starts with world war 2. that's don't judge the guy for water at the united nations. singaporeans would argue that the story goes back a lot longer. but 1942 is certainly when the issue rep that was attention. that's when and i troops, namely british australian and indian forces with best thing, specialist japan on seeing the pull island, which at the time was a british colony. the dns, dependent on imported water, which was a bit of a problem with japanese was blew up the pipes transporting that water. the rich, the connex, malaysia, and singapore was bones. the result was lack of water in the city, a terrible if there's other water scars, the t v l has lost the battle of singapore. but after japan's overall surrender, the island remains and petitions. it took more than 20 years until it became fully independent. but politically ration didn't free single pull from its water crisis.

what's arresting? catastrophic sanitation and regular floods continued with its faith now in its own hands. seeing it will begin planning for a long time to see that the ta spend almost 3 decades researching what the policy and innovations around the world and assess the native busing and post path. she never gave me the pin and they started running to be watching the band as well as putting the band in energy independence. but they are going to have she stance up kinds of things. so that was in 1965 for 2016. the initial master plan was fine tuned over the years into a what a strategy which they called at for national taps. the 1st what the impulse 2nd, diesel, the nation, that local catchment and forth something they call new water. let's dive into it. firstly, single put new, there was plenty of water rights,

2 deals to input water from malaysia and the sixty's got the types running again. it's cheapened, millions of lease is up pumped over the board every day. but buying have a fuel water from your neighbor, isn't sustainable long term. on the country from the stock malaysia, i made threats to cut off the supply and argued over its price. the tensions have even led to warnings of the military conflict. single polluters know that weak spot, so they want to stop importing water by 2061. so it's all more important that the other 3 types become more than a drop in the ocean. water planning is very important because they have so little water. they must single, there must make sure of that, so this waterways use the lice me and the objective of this master plan is to make the most out of every single drop of water. these means keeping rivers and drain screen, investing billions, starting to collect to mobile, to cleaning it, and use what the island state singapore already has. for example, this,

the ocean celebration, the celebration this hell a nation. you fix that under linkable salt water. you remove the sold and you have unlimited supply of fresh water. do you remember? we had an entire video about obtaining fresh water through the southern nation. it's use it a number of extremely drive places around the world and is a real game changer for some men bring the saw the nation to use as pressure. so to authors, you have color thing, read for clarity suppressed into a membrane that is only partially permeable, fresh water, compressed through color and blue. but the sol district on the other side, single, really pushed to advance. this technology is underground facility. for example, the state of the arts, normally it treats used water in terms of the drought. it diesel, the nights, the water on top, because it is a park. today, 5 to southern nation plans provide up to 25 percent of the entire islands water supply. single floor plans to increase its capacity to meet 30 percent of its needs

in 2016 by which time warranty was expected to have doubled. but that's no way near self sufficiency. so what's next? bengal, right. a lot of it and single is a master of mixing that out to a 3rd of the entire state stuff is, is used for rainwater catchment. basically the water falls on the roof. uh and then uh, it goes through the drains. uh and then uh you make sure that series as little uh, water leaks from the uh, from the drains and is uh, is captured in by the drainage system and, and conveyed to reservoirs where it can be stored in and treated for further use an extensive network all for those canals and drains channels, the water into 17 was of was the biggest is why we never us with an area of 10000 texas. it was back fresh water from flowing into the ocean and helps to control

frequent floods. so does this underground tank that catches flood walton extreme cases when the drain spill over. even this was i could potentially be treated and reused by 2060. the government wants to use 90 percent of the land to area for rank catchment pitching rain. water is one thing, but what about the water already in circulation? o drainage water is collected and, and treated and reused as much as possible. most countries they do not invest, not even a fraction of what a single pores invest in the water authority is billed to 206 kilometers, 2 inch pipe highway, costing $10000000000.00 that guides the city sewage into state of the reclamation and cleaning facilities okay, seeing a post by some as the 5th, which is country in the world. so it kind of faults a special like that. it's also a lot easier to push through such projects when you have to sort of control

democracy, run by the same party that single plants had since independence in 1965. anyway, the entire cities on a growing is basically one big sewer network. but the pride of single pulls water strategy is what happens after collecting the water the treatments go 30, call it new. what is produced by micro situation versus most us into v radiation some of that water is so high quality, singapore is using it in their chip manufacturing industry, which requires old for pure water, which is an indication of how good a quality of that water is. did you know that around the world? half of all waste water is released untreated, and only 11 percent is actually reused in singapore? about 30 percent of the entire drinkable and non drinkable demand can be met by recycling, use water. and they want to increase that to 55 percent by 2060. the most of

it is used by industry. only a fraction of it is mixed into the drinking water supply. because we also squeamish it's controversial because we're taking waste water, which, you know, we goes down our drains, we flush or down our toilets industry dumps waste water. and we typically think of that as of a liability is something to get rid of. so how do we get people on board using the flush save assistant bag and said with every flush, make saving what the pay reduce water consumption, save up to 10 liters of water per dollar. nationwide campaigns encourage people to install what the saving fittings and nicely, if you install those fittings to get the discount votes as part of the sustainable products just to what time the district each households, water consumption and detect leaks and pipes, that's all single comes down to an incredible 5 percent. what are those from leaks which is 1st class globally, the average is estimated to be 30 percent. what they've done incredibly well in my

opinion, is on the side of water education. they've been educated, their community about their water situation, about their water challenges and about the solutions that they've chosen to put as good as simple as doing it has the big advantages of other countries besides being rich and the type of control society. the city only has a tiny agricultural sector and can focus almost entirely on oven and industrial waste water. so they have one problem less as food production fluids and consumes. and normally the amounts of fresh water in many parts of the woods. despite that, they've shown a lot as possible anyway in the water we, we stop a hey, i've been talking to her watching when we was here with madison. how can it be improved? how would be involved? how can we pay for it based on who is it but, but can we do but punishing the police not using the police?

how is she that we're going to do tricia? i really found perspectives rocking. he sees that they will bait fast. so wednesday said she still hasn't, they can do this things happening. so to sum up, incentivizing low cost, both a saving for things could be easy for every government to implement the cell. the nation is only an option for coastal regions and it requires a lot of energy of dirty fossil fuels, single polls, catchment treatment and purification facilities. our world class as the result of a lot of investment in innovation and research. but it turns out that a dollar invested in efficiency improvement is much more productive than a dollar invested in new supply. reusing waste want that seems a no brainer. it's safe and tested to work and the tech is available. this is really important to us to find the best solutions to, to every countries providence, but also long term planning. a single bore from,

from all the way from, from independence as being planning is way through. what are security? a single port is extremely high on the political agenda all the way up to the, to the prime minister is something which is mainstreamed in each and every policy adopted and implemented by, by the country. seeing if it was blazing a training and testing some of the what's the biggest, what the challenges in the phase of climate change. it's not just about money, but also about decision making. policy and long term planning. some of the ingredients with which any region could make it from water racks to riches. the climate change particularly scary for the younger generation. and this

time they feel helpless. all the ways out of this power tomorrow today. next on dw ghost towns and so didn't cities, the bomb shelters and nuclear bunkers from the cold war. the ceremonies underground secrets are gradually being uncovered and some are even being made accessible to visitors. but only under strict security protocol. in 45 minutes on d, w, conflicts, crises was, every single connection mapped out shows the geophysical reality. the on the board

is what makes things the way they are mapped out, navigating a changing world. now, on youtube, the severe storms, forest fires, record breaking heat worldwide. we are alarmed at the same time fuel powerless. international studies show that young people in particular, are very worried about climate change. what can we do about it? the threat global warming poses as not only to the environment, it's also becoming an emotional test for an entire generation that topic and more coming up on data science show. welcome to tomorrow. today.
