we start this week in one of europe's most breathtakingly beautiful destinations, venice, in north—east italy. this city on water is made up of over 100 islands, interconnected by a labyrinth of picture perfect canals and elegant bridges. life around here has remained the same for hundreds of years and steadfast through that time have been the gondoliers of venice. they see themselves as custodians of the city. today, there are only 400 gondoliers left and they are almost exclusively used by tourists.

so it was in the family? with the local population of around 50,000 people walked by 20 million visitors every year, the gondoliers aren't short of a customer or two. and while that is good for business, the numbers swelling the main tourist areas inevitably create a huge problem. increased pollution, including discarded junk clogging up the famous waterways. but now some of the gondoliers who ply their trade in the 276

canals are doing something about it. they hope to solve at least some of the problem with a voluntary initiative to perform regular underwater canal clean—ups. what gave you the idea to start cleaning the canals? dredging up tonnes of rubbish ranging from shopping trolleys to car tyres is a mammoth and potentially dangerous task. so the men are given bespoke training. they dive using specialist equipment in order to operate safely.

and early on sunday morning, long before tourists arrive, i'm joining the guys for the real deal. that is one hard—core scuba—diving suit. there is not one bit of skin showing. i've dived before. i'm not sure i'd want to go into the canals of venice, as lovely as they are. i want to find out what the newly trained canal cleaners have to contend with. stefa no. ok, so what is all this? the heart of the operation. the teams have to stay in constant communication. it is crucial to help the guys underwater cope with the difficult conditions. it must be very dark and gloomy. can you see?

ok, you go by feel down there. so, stefano, how often do you do this? every sunday? much of today's catch is all too familiar. right. since the clean—up began, some 4000 carelessly discarded bottles have been retrieved. but later, a baffling object rears its head and has everyone mystified.

there is something really big on the line here. it looks really, really heavy and there is about three of them trying to pull it out. what is that? oh, my goodness. it's a trolley. it's probably somebody�*s luggage from about 20 years ago that went off into the canal. look, it has been down there for so long it is covered in barnacles and slime and sludge. is that coral? is it sponge? no, no, these are sponges. wow. 0h, there's a rope. what's it like down there? mud, mud. mud. is it dangerous down there? the equipment they use is full protection against the pollution. because the problem is not really the water itself but the mud.

the mud is laying in the canals years after years and is full of bacteria and chemical pollution. but what about the gondoliers when they are working? is it difficult if there is rubbish? yes, yes. when the tide is low, they feel something in the water that is not the real sea floor. you know? yeah. canals must be cleaned to transfer this idea to the public is very important. and also for the sensibility of people, people living in venice and also tourists. that they don't have to throw things in the canals. once the rubbish has been retrieved, gondoliers hand it over to the local council

to dispose of it correctly. it has been an impressive haul today and that is just from one trip. so with another 200 or more canals to go, something tells me they have got a lot to keep them busy for some time yet. so next time you are enjoying a leisurely ride along the waterways of venice, spare a thought for the gondoliers who donate their time to clean up the canals, even if they haven't mastered singing underwater yet. and if you are interested in a few days in venice in the near future, here is a round—up of the best the city has to offer. all through the summer to november is the 59th venice biennale. as the name suggests, the contemporary art exhibition runs every two years. but due to covid there has been a three—year gap. this year is heavily weighted towards women with 90% of the main exhibition given over to female artists.

burano is a picturesque island in the venetian lagoon, famous for its handmade lace and colourful homes. go for a few hours in the morning or afternoon to wander around and take in the tranquillity and calm, away from the hustle of central venice. whatever you do, don't forget your camera. from burano you can then stop in to murano on your way back. this island is famous for its glass—making, which is considered a fine art. it dates back to 1291, when the venetian government ordered glass—makers in venice to relocate to murano to avoid causing a huge fire. you could even find a workshop to try your hand at the craft. as we reported last month, from january 2023 you will have to pay a daily charge to enter if you aren't spending the night in the actual

city itself. 0vernighters already pay a city tax at the hotel but for day trippers you will need to pre—book your slot and pay through an app. prices will vary between 3 and 10 euros per person, depending on how busy it is. still to come on the travel show... we meet the restaurateurs bringing hope to ukrainian refugees in london. i think that food can find a wayjust in the middle of the heart. it's that time of year again where summer is in full flow in many countries around the world, which means one thing... festival season is finally upon us and after seeing cancellations of some of the biggest festivals over the past two years due to covid, i am more than ready to put on my boots and visit

a campsite or two. to me, a music festival is the perfect place to unplug and unwind, all to the soundtrack of some banging tunes. i have spent way too much time on my sofa in recent years, so i feel a bit loath to sacrifice my home comforts, even if it is just for the weekend. and if you feel the same way i do, help is at hand as i take a look at some of the best gadgets to chuck into your rucksack this summer season. so first up is your festival accommodation. i have got the quechua two—second 3xl. now, if you weren't in the scouts or the girl guides, which i definitely wasn't, then camping might not be your thing. but this tent has the potential to become a firm festival favourite. that is because, as the name implies, it apparently pops up in just two seconds. so let's put that to the test. start your stopwatches.

so, it didn't quite go up in two seconds but i think that has more to do with the person putting up the tent the natural tent itself. now it is up it is pretty spacious in here. whether you want to keep it all to yourself or share it with your friends and what will feel an absolute godsend is a special lining that blocks out heat and light, which will be more than needed after a night of partying. right, i think it is time to check out some headliners. don't you just love going to a festival nowadays and seeing your favour act through a sea of phone screens in front of you? but there is a new gadget designed to make the way we watch live music change forever. these new glasses are designed to keep you in the moment and keep your followers up—to—date thanks to these nifty cameras that happen to

link up to your social media. and with a quick clip or two we have photos and video sent to your phone ready to upload. i just love the fact that i can film hands—free effortlessly, i can listen to music, i can make and receive calls on these things. of course, filming stealthily on a pair of glasses is not without its privacy issues. it has a little led that pops up to let people know that you're filming although i don't know how visible i will be in direct sunlight. then you have the download content of your phone to free up more space. and i was told on more than one occasion that these things had overheated which felt a bit disappointing but overall i am a massive, massive fan. these are awesome.

but before i go, i want to test out these bad boys. guys, crank it up to 11. so the reason i wanted the band to play something loud is because i was testing out the flare audio isolate prose. when you're at a festival the last thing you want is that ring in your ears following the third night in a row of banging beats. what these buds do is turn down the volume without reducing the quality. when you pull them out you realise just how loud the music is. they really do a really good job. but don't worry, festivalgoers, i have one more gadget for you yet for when the dirty beats aren't the only thing. the foot pump builds a pressure which allows the shower to work. oh, it is cold! so clearly it is not going to rival your shower

at home but it definitely beats baby wipes. you will be the envy of the campsite. it is not really the kind of thing that i would want to bring along to a festival but if one was there on the site i would definitely use it. because after that i'm feeling a lot cleaner and a lot more refreshed. and finally this week we are in london, where a ukrainian couple are embarking on a business venture to help those affected by the conflict back in their homeland. we sent a reporter to see how they're getting on. the war between russia and ukraine has been going on for over 20 weeks now. more than 5 million refugees have fled ukraine and millions more have been displaced within the country itself.

butjust here in london's earls court, in this unassuming building, there is a ray of hope. because one ukrainian couple are creating opportunities for some of these refugees in their new restaurant, whose name means dream. the restaurant is very much a work in progress but they are dreaming big. and every effort is being taken to evoke the spirit of ukraine. this is the bar area. this wall will look like the wall in old houses in ukrainian villages where they didn't have proper building materials and they were using straw and clay. so it will be uneven, very authentic way how ukrainian is used to build the houses. we arrive to london five days

before the war started. for us it was a short work visit and we have return tickets which we never used. when the war started we made a decision to stay here. and how did you feel at that point because you are stranded here and you had close friends and family in ukraine? all the time since the 24th of february you are receiving just bad news and it's very, very exhausting. since they've been in the uk, they have helped raise hundreds of thousands of pounds for ukraine through events with celebrity chefs like jamie oliver and tom kitchen. that is part of our mission, not just a fundraise but also to remind the world community about ukraine through the language of food. so we are giving employment to ukrainian migrants and then we want to fill this place

with ukrainian energy through textiles, furniture and all other beautiful things which talented ukrainian artists are creating. undeniably, the main draw is going to be the food. something the head chef is very passionate about. he is even a culinary ambassadorfor ukraine. why is it so important for you that people here and around the world know about ukrainian food? i think that food can find a wayjust in the middle of the heart. because of diplomacy, it is always about the brain, you are talking, trying to find some special ways. but the third is coming to the heart and afterwards your brain. you even can change your mind after a good dinner. so here is five days fermented cucumbers. wow.

i want to give you a piece to taste. today the day when we put in a can. that salt is in here? yeah. it is the most popular salt in ukraine but now the place where they're producing salt is a battlefield. so the factories closed. you can't get it. it is finished even in ukraine so when i found it here in uk i was happy like a baby. i bought everything i can find. let me try. sure. that is such a rich, tangy, lovely taste. joining me for my bowl of food is a ukrainian refugee who will be working as a way to hear when the restaurant opens in a few weeks�*s time. so let's just start from the beginning really which is how did you find

yourself in england? what happened ? 0n the 24th of february the war began. we had to think about the ways to flee the war basically from ukraine. because unfortunately there is not a single safe place in ukraine. so the city that i was in also got bombed. so my mum just insisted on me leaving. how difficult is it to do this when you know what's happening back home? it is really hard, and i am on the phone with my mum all the time. i am always checking the news. i wake up with the phone in my hand and i go to sleep with the phone in my hand. it is very pressuring, i would say. just finally, why do you think it is important there is this restaurant specialising in ukrainian food with a top chef? why is it important

to have that here? i think it is really important to show culture because everyone knows about russian culture but not many people know about ukrainian one. so it is really important to show people that we have a deep, diverse culture with different traditions, different food that is really tasty and amazing. and that would be great to show that to people. i've got to say, i'm struck by the resilience of the ukrainians i've today, and the strength of their community. and hopefully one day in the not too distant future, dasha's family will be able to visit the restaurant for themselves. well, that is it for this week. coming up next time... we visit the greek island one year after the devastating forest fires that occurred there. to find out if the island's tourism industry is ready to bounce back. i have been sent in pictures

of the place that we are on our way to. looks lovely. it looks really lush, green, fertile. but i've been told since the fires have hit this whole area, it now looks very different. even looking out the window, look at that. just as far as the eye can see, all you are looking at is burnt trees. and don't forget you can catch up on the bbc iplayer. we also on social media too along with a whole host of delights from across the bbc. but until next time from all of us here in venice, it's goodbye.

hello. we have big weather contrasts across the uk. there were outbreaks of rain particularly in the north—west. some cloud was low with mist in commonwealth. across the hampshire area, a dry day and that has been one of the features of the weather for july. there has barely been a drop of rain. southern wales, eastern england to and in parts of hampshire there has not been anything very measurable rain wires so far this month. indeed, although there is rain in the forecast, there will be little if any reaching parts of east anglia and england where it has been particularly dry. 0n it has been particularly dry. on saturday, we did have some pulses of rain. it turned quite heavyin pulses of rain. it turned quite heavy in the end of the day

across western scotland and the area responsible will continue to feed up some soupy air. it will be humid to take us sunday. some high temperatures on the cards but not near the records we set on tuesday. the rain is going to be quite heavy at times for northern ireland, western areas of scotland. they will be a pulse of rain crossing wales and maybe reaching the peaks in the afternoon. to the south—east of that, it is dry with warm spells of sunshine and temperatures will be higher than they were on a saturday across the board. quite a big jump up across the board. quite a big jump up in temperatures in aberdeen. it will be hottest across east anglia will be looking at highs up to 30 celsius. sunday evening and overnight, well, we will continue the south—westerly winds for a time across england and wales but nothing towards east anglia in south—east england. we will get a further pulse of rain for scotland and northern ireland but here we will get north—westerly winds feeding in and they are as a

result of this area of low pressure slowly transferring eastwards. the north—west will drop the temperature a little bit as we go through monday and there is still a bit of rain in there is still a bit of rain in the forecast. it looks like it could be quite a wet start to the day in northern scotland and maybe some of that waste skirting down into england to. otherwise, a few showers otherwise, a few showers around. quite a bit of dry weather with some sunshine and temperatures down. generally high teens for scotland and northern ireland and into the 20s for england and wales and warm in east anglia and the south—east of england but not as hot as it has been. now, taking a look beyond that through the rest of the week, high pressure will be in charge. i think day by day we will notice those temperatures tending to rise, but there will be some low pressure system is working towards the north—west of the country, threatening rain at times. tuesday is working towards the north—west of the country, threatening rain at times. tuesdays and large a dryer kind of day with a bit more in the way of sunshine in the morning and clouded the afternoon and showers in the north—west of the uk, and temperatures art near average really. about 18

for scotland and northern ireland. that is perhaps a little bit below the 23 in london is not far off what we should see. with high pressure hanging on across parts of england and wales it should be dry and bright in newcastle. scotland and northern ireland always have bigger cloud and there will be some rain around particularly towards the end of the week. the rule of thumb is the week. the rule of thumb is the further south at the dry out the weather gets and with that area of high pressure holding across wales and east anglia it is essentially a dry week and those temperatures will be climbing. it will become a very warm, if not hot, towards the end of the week. that is the latest weather. by now.

this is bbc news. i'm gareth barlow. our top stories. there's been widespread condemnation as missiles hit ukraine's 0desa port — hours after russia signed a deal with ukraine allowing grain to be exported to millions around the world. no matter what russia promises, they will always find a way to break them. that may be through geopolitics or with weapons, sometimes through bloodshed. it has many ways to act. the world health organisation, declares the monkeypox outbreak, is now a global health emergency. wildfires continue in north america — as authorites in china and europe try to combat scorching heat and soaring temperatures.
