[00:01:02] the executive board of the National Bank of Serbia, Alta
[00:01:06] bank, had its license revoked, the Prosecutor's Office for Organized
[00:01:09] Crime announced the filing of criminal charges against several
[00:01:13] responsible persons, the Alta Bank advertisement disappeared from the jersey of
[00:01:16] Crvena Zvezda basketball players, it was not on their backs, on
[00:01:20] the training shirt it was covered with a white
[00:14:22] Referendum losers? The purgatory of the proud, media poisoners, and
[00:14:25] secret services still in operation, persecution and last days. The MUP
[00:14:29] ignores Toka's orders, Macurina's bank gave a loan of 12
[00:14:32] million euros to a businessman accused of attempted
[00:14:36] murder.
[00:14:37] I
[00:14:41] want to inform you that based on
[00:14:44] the stratified
[00:14:46] sample, it is clear
[00:14:49] that we lost these elections. The student-blocker
[00:14:53] won.
[00:15:07] it's over, it's over, it's over, the largest number of them headed to
[00:15:10] Slavija to celebrate this
[00:15:12] victory,
[00:15:16] the most beautiful presenter,
[00:15:19] thank you, there will never be such a Serbia again, which was
[00:15:23] ruled by such a man as he was. Thank you very much, we are starting to
[00:15:26] change things for the better, thank you very much, thank you, Mileva
[00:15:30] Dimitrijević, candidate on the student list, we are still here
[00:15:33] review, student movement, but also civil.
[00:15:37] protests that had their epilogue tonight. The Serbian
[00:15:41] Progressive Party, after more than a decade, lost
[00:15:44] power. A symbol of slavery.
[00:15:47] Onovo Pioneer Park. No more slavery. This was until now, no
[00:15:51] longer. I adore you, you are the greatest emperor in the world. Okay,
[00:15:54] what are your impressions tonight?
[00:15:58] It's like a dream, it's like a dream. Students win, they have
[00:16:01] 141 mandates. Serbian Progressive Party
[00:16:05] 103.
[00:16:07] Thank you, thank you for everything, long live freedom, from
[00:16:11] tomorrow we build the future, thank you for your attention
[00:16:14] and good night, stay with N1, see you.
[00:16:41] In Europe, the summer of 2026 was one of the hottest
[00:16:44] since record-taking began. When temperatures climb that high,
[00:16:48] cities turn into ovens, movement is exhausting, and
[00:16:52] everyone seems on edge. We need to do more to adapt,
[00:16:55] particularly in urban settings. More green spaces could be part of the
[00:16:59] solution.
[00:17:02] This and more on DW's science show. Welcome to
[00:17:06] Tomorrow Today.
[00:17:12] Can we redesign cities before urban heat
[00:17:15] becomes even deadlier? This researcher is on a mission to do
[00:17:19] just that. Fabian Brantenburg and his team in Leipzig
[00:17:23] use green building and urban design along with storm water
[00:17:26] technology to help defend Germany's cities against the
[00:17:30] blistering heat caused by climate change.
[00:17:34] Cities are typically hotter than their surrounding environment due to the
[00:17:37] high density of materials like metal, concrete, and brick that
[00:17:41] absorb heat. Lack of vegetation also plays a
[00:17:44] role. During extreme heat, air temperatures
[00:17:48] in inner-city centers can be higher by up to 10 degrees
[00:17:51] Celsius than the adjacent rural and suburban
[00:17:54] areas. This is a danger for the people who live in urban settings,
[00:17:58] in particular the elderly who are especially vulnerable to hot
[00:18:02] weather. Fabian and his colleagues
[00:18:06] investigate the cooling impact of patches of plants and swamp
[00:18:09] vegetation on roofs, where the conditions mimic
[00:18:12] marshland, compared to roofs covered in
[00:18:15] gravel. What we can see is
[00:18:19] that the surface temperature of the roofs
[00:18:22] is, um, several degrees lower in summer when you
[00:18:25] compare it to the gravel roof. The green
[00:18:29] and swamp roofs act as an extra layer of
[00:18:32] insulation, just the soil, the
[00:18:35] substrate, or in case of the swamp green roof, the
[00:18:39] water, um, act as a as an insulation barrier just
[00:18:42] like you would normally insulate your building, um.
[00:18:46] And in addition, you have evapotranspiration effect,
[00:18:49] so, kind of, the building is sweating just like we
[00:18:52] would, and the evapotranspiration then cools the
[00:18:56] building. Water for evapotranspiration comes
[00:18:59] mainly from rain, which fills gaps in the soil when it
[00:19:03] falls. Roots absorb the water and draw it upwards through
[00:19:06] the plant's body. It's then released through tiny pores in its
[00:19:10] leaves as water vapor. This vapor has
[00:19:13] a cooling effect on the surrounding air. In urban areas, it
[00:19:17] can amount to as much as 4 degrees Celsius.
[00:19:21] If
[00:19:24] evapotranspiration is one way plants cool their surrounding
[00:19:28] environment, another is shade from their
[00:19:30] leaves.
[00:19:33] These are Germany's first tree trenches. They collect
[00:19:37] storm water to prevent flooding, and that water is
[00:19:41] handy in times of drought. What we
[00:19:44] saw here over the past years of drought is that a lot of trees
[00:19:48] actually died and thereby they lose their infrastructure
[00:19:51] function, so to say, so they don't provide any shade and they don't evaporate,
[00:19:55] transpirate any water and
[00:19:57] by
[00:20:00] specifically infiltrating rainwater at the
[00:20:04] tree trenches or at the parks, we can keep the tree
[00:20:08] alive and thereby it keeps its benefits like shade and
[00:20:12] evapotranspiration. The tree trenches can give the plant's
[00:20:14] roots more space underground. Combined with
[00:20:17] collected stormwater, this can lead to bigger canopies and better
[00:20:21] shading, which means cooler streets. Green
[00:20:24] infrastructure can be as simple as a
[00:20:27] cobbles which let vegetation through, or funnels
[00:20:31] channeling storm water towards surrounding
[00:20:34] greenery. New buildings could pump gray water,
[00:20:37] waste water not contaminated with feces, to the green
[00:20:41] roof. An experiment here shows plants fed with waste
[00:20:44] water thrive even more than those fed with tap water.
[00:20:48] The system helps keep plants alive when water is
[00:20:51] scarce and could help them provide more shade in the
[00:20:54] city. The scientists also work with
[00:20:57] rainwater collected by their green roofs. They
[00:21:01] found that piping the rainwater down the walls has a
[00:21:05] cooling effect. The research may prove beneficial
[00:21:08] further afield than Germany. Especially
[00:21:11] in regions where water is scarce, blue-green infrastructures are
[00:21:15] especially important because they not
[00:21:19] only retain water
[00:21:22] on top of the roof, but they also infiltrate it and can
[00:21:25] recharge the aquifers or the the ground water.
[00:21:29] Clean water scarcity is an issue for Indonesia's
[00:21:33] cities. This is a professor, an
[00:21:37] expert in the field. In Indonesia,
[00:21:41] green roofs make a lot of sense, and the reason is,
[00:21:44] like, in contrast to Germany, where there are only a few
[00:21:48] weeks where it's really, really hot, in Indonesia it's most of the year quite
[00:21:52] hot, and additional cooling, um, actually
[00:21:55] has, like, the benefit, it cools down like for all times of the year,
[00:21:59] so that's like a huge additional advantage that the
[00:22:03] benefits actually spread out over the year. Having
[00:22:07] a standing body of water like a swamp on a roof in
[00:22:10] Indonesia could be problematic for controlling
[00:22:13] mosquitoes, though. But
[00:22:15] green roofs, because they retain water, could help protect
[00:22:18] a city like Jakarta from flooding during storms and therefore
[00:22:22] reduce sudden runoff. However, Indonesia's humid
[00:22:26] climate could raise issues. In
[00:22:29] Indonesia, like, um, plants are different, like, of
[00:22:32] course, there's importance to use native plants.
[00:22:36] It's more humid, um, plants are growing faster, and that can lead to
[00:22:40] structural issues like, um, you need like
[00:22:43] earth and the plants itself, the biomass, it's, it's weighing, so
[00:22:46] like the buildings need to be stable enough to carry the
[00:22:50] weight of the biomass, and that's an
[00:22:53] important consideration.
[00:22:55] A common criticism of green roofs is that the cost of
[00:22:59] installing them is just too high, but Fabian
[00:23:02] says blue-green infrastructures will actually save
[00:23:05] Leipzig 700 million over the next
[00:23:08] decade, and by lowering urban temperatures, installing
[00:23:12] greenery to reduce extreme heat will also
[00:23:15] save lives.
[00:23:17] Do
[00:23:38] affecting biodiversity?
[00:23:41] Plants, animals,
[00:23:44] fungi. We share our planet with millions of other
[00:23:48] species, all interacting in
[00:23:50] different environments. This is what we think of as
[00:23:53] biodiversity, and it's threatened by climate change,
[00:23:56] especially by rising temperatures.
[00:24:00] Habitats often change faster than the species that
[00:24:03] live in them can adapt, like the polar
[00:24:06] bear. Polar regions have grown warmer in the last few
[00:24:09] decades, causing vast stretches of sea ice to
[00:24:13] melt, and that's having an impact on polar bears, which depend on the
[00:24:17] ice to hunt seals.
[00:24:19] Elsewhere, water is growing scarce. Forests are
[00:24:23] suffering as a result. Trees don't react quickly to
[00:24:26] environmental change. They take a long time to reproduce
[00:24:30] and adapt to new circumstances. When
[00:24:33] weakened by drought, they absorb less CO2 and
[00:24:36] produce less oxygen. That leaves them more vulnerable to
[00:24:40] pests and wildfires.
[00:24:44] Climate change is also altering the timing of some natural
[00:24:48] events. Many plants now
[00:24:50] flower earlier in the year than they did just a few decades
[00:24:53] ago. This is causing major problems for
[00:24:56] bees. They arrive too late and miss out on important
[00:25:00] food sources, and plants miss out on their pollinating
[00:25:03] services. Warmer temperatures are also causing some
[00:25:07] caterpillars to emerge earlier. That affects birds
[00:25:11] like the Great Tit, which raises its young in tandem with the insect's
[00:25:14] life cycle. If the caterpillar prey has already
[00:25:18] pupated, it can seriously disrupt a crucial feeding period for the young
[00:25:22] birds. The effects of climate change on
[00:25:26] biodiversity are complex and often less
[00:25:29] visible than melting glaciers or dried-up
[00:25:32] rivers, because in an ecosystem,
[00:25:35] everything is interconnected, and when
[00:25:38] one species suffers, the consequences can have an
[00:25:41] impact on many
[00:25:43] others.
[00:25:47] Meadows and forest ecosystems are home to a remarkable number of
[00:25:51] species, but that diversity is now under threat. Using a wide
[00:25:55] range of methods, researchers in Germany are looking into what causes
[00:25:58] biodiversity loss. I'm...
[00:26:41] species and the species composition. The goal is to find out how plant
[00:26:45] diversity affects both wildlife and the
[00:26:48] soil. Researchers use a range of
[00:26:51] tools to measure
[00:26:52] that.
[00:26:56] Here they're testing how much sunlight makes its way through the
[00:26:59] vegetation to the soil.
[00:27:05] Something else the researchers are interested in is soil
[00:27:08] moisture.
[00:27:12] They even use a vacuum cleaner,
[00:27:30] unabated vacuums one cubic meter of air and
[00:27:34] vegetation to find out exactly which insect
[00:27:37] species live in the different sections of the
[00:27:41] them there are.
[00:27:45] And she checks whether there's a link between the number of plant species
[00:27:48] and the number of insect species on the various test
[00:27:52] plots.
[00:27:58] Another experiment aims to find out with the help of decoy
[00:29:32] control, which is effectively what predation is,
[00:29:35] increases when we have many different species in an
[00:29:38] ecosystem.
[00:29:41] The more varied and numerous plants there are per square
[00:29:44] meter, the more insect predators, like lacewing
[00:29:48] larvae that feed on aphids, or
[00:29:51] ladybugs. High plant diversity therefore
[00:29:55] promotes natural pest. control. the
[00:29:58] plots with the greatest plant diversity also perform best
[00:30:02] when it comes to soil, moisture and biomass
[00:30:05] production,
[00:30:08] plant diversity had huge positive effect on the vast
[00:30:11] majority of the processes we studied, and the
[00:30:15] more plant species there are, the more
[00:30:17] butterflies,
[00:30:20] the more beetles
[00:30:21] and
[00:30:25] the more spiders, making
[00:30:27] the meadow an especially productive
[00:30:30] ecosystem, but analyzed data from
[00:30:34] 2010 to
[00:30:35] 2020
[00:30:43] and in that period alone some groups declined by as much as
[00:30:47] 9% per year, when we lose
[00:30:50] species, we also lose the functions they perform, that's
[00:30:53] crucial, not only for people who enjoy walking through medow, but
[00:30:57] for all of us, if we no longer have pollen.
