narendra modi, with a potential bilateral trade deal on the cards. now on bbc news, the travel show. thailand's landscapes are like something from a dream... ah! imean... i mean, look at this. this is absolutely stunning! ..from dazzling coastlines to lush countryside and wildlife that will take your breath away. visions of paradise that in normal times attract more than 30 million of us every year. but that weight of numbers isn't necessarily good news for this country's fragile natural heritage. the boats are disturbing the sediment and that also harms a lot of the coral reef in this area. as far as caves go, this one is very impressive. oh, it's like paradise. there's so much to explore. we should preserve this. this week, i'm in thailand, one of asia's most visited destinations, to ask — might its staggering beauty be one of its biggest challenges? this is the andaman sea. it runs along thailand's west coast and i'm about an hour offshore, on the hunt for the perfect, perfect beach. if you're looking for somewhere picture—postcard pretty, you'll be wanting this stretch of coastline. it's all the cliches — palm trees, emerald seas and lovely stretches of sand. this is the thailand i've been waiting for. this. i'm getting off at maya bay. it's famous for its attention—grabbing role in the hollywood movie the beach, starring leonardo dicaprio. in it, the characters hear rumours of a totally secluded and unspoilt paradise. the movie's success brought sightseers in their thousands. so i came here around 2015, so about eight years ago, and, honestly, all i can remember is just seeing so many boats, just boats upon boats, that really... you couldn't really see the water, you couldn't appreciate the colours. there were people, so many people, on the beach. there was quite a lot of rubbish as well. and ijust remember leaving, feeling quite deflated. in 2018, it all got too much and the bay was finally shut. there were four years of intensive conservation work and this january, it was reopened with new rules. boats are banned in the bay and swimming in the sea is strictly forbidden. blows whistle there's lots of rules and restrictions in place here. how did you feel about them when you discovered them? i understand it. i understand why there's, like, rules and why there's, like, a fee that you need to pay to maintain how beautiful this bay is. i totally understand that. just, i didn't expect a beach where you're not allowed to swim. water is actually greenish—blue. we have never seen this colour of water anywhere. and it's a good thing that you are trying to save that. you are not allowing swimming or any such thing over here and trying to save the marine life. at the peak of its popularity, around 4,000 people a day would come to this beach, but all that activity killed off 90% of the coral and saw off the blacktip reef sharks that mate here. may has spent the last six months monitoring the shark populations to see what happens now tourists are allowed back. they are using this area to hide from the bigger ones that are like in the deeper area. yeah. so, that's why ask people not to swim, because then, the baby sharks have a safety area. have you seen any this morning? that is one! ——there is one! we have seen a lot of them coming back, so we have counted, like, the highest number is 161 sharks. wow! yeah, in november 2021. yeah, it's really nice. what was the problem with the tourists and the sharks? the boats are disturbing the sediment here and that also harms a lot of the coral reef in this area, so after the ecosystem kind of deteriorate... yes. ..the shark is not coming in because the fish is not here. the tech may uses is pretty simple — a bag of mashed—up fish and a camera attached to a metalframe. and then, it's just a case of finding a good spot. we are about to put the camera down to film the shark for one hour. so, we do this four times a day, so that we can get, like, a behaviour data and also photo identification. 0k. yeah. we want to get a good photo of the dorsal fin and also, we want to see what they're doing underwater. yeah. so, are theyjust cruising around, like, passing by, or are they attracted to the bait, or are they start nibbling on the bait? oh, there we go. none of them are going for the food yet, though. is that because this isn't... you said they feed more at night, right? yeah. if it's night—time, they are really crazy. yeah. so, some of them take a long time to come close. and some of them are really fast. we can see that each of them have personality and then, when we photo id them, different months, we can see if the same one comes back. are you hoping that the strict regulations, they stay in place and they're enforced for the foreseeable future? yes. i really hope that. that would be for the greater good of the sharks and your research. and also for the harmony between people and nature. yeah. but despite what's happened here, thailand is hoping to double its visitor numbers in the next four years and i can't help but wonder how these beauty spots will cope. a good proportion of those new arrivals will pass, like me, through this place along the way. get out the road! yes! skipping traffic, that's what i like to see. it's no secret that the traffic here in bangkok has been awful for years and it's not that uncommon for drivers to be stuck in traffic or trapped for hours, as they crawl their way through the city and as a result, the pollution here can get quite bad. to encourage more people off the roads, the city's about to expand its public transport system. work�*s beginning on new lines for the skytrain, and on the edge of the city, a vast, newly—opened international railway station. i'm not actually surprised i'm lost because this is the biggest train station in southeast asia. as far as stations go, it's huge, sterile, loads of air—con. right, platform four. where are you? billions of dollars is being spent on new rail links, primarily into china. but wherever you're going, a journey on the trains here represents value for money. so, a first class ticket will set you back 222 bahts. that's just under £5. and it's so cheap, considering you're getting around seven hours' travel out of it. but there's no air—con and the seats are pretty hard, so you have been warned. there are second class options, if you want a bit more comfort, though. some of the more popular routes include chiang mai to bangkok and bangkok to the southern beach resorts. you can even go international. so, east to laos and cambodia, and even as far as malaysia and singapore. but i'm jumping off at a stop that will get me within easy reach of thailand's lush countryside. i've arrived in a province called surin, which, as you can probably tell, is pretty rural and remote, but it's also home to some pretty special residents. surin is the spiritual home of the mahouts, or elephant handlers. around a quarter of all the country's domesticated population are said to come from here. saeb used to work in the northern city of chiang mai, charging people for rides. hi, saeb! i want the tour. you've got to show me around. so what's this big fella's name, then? ekasit. and how old is he? 38. 38! is that quite old in elephant years? yeah, yeah. so shall we get more food? he's running out. wow! he's a big guy. eats a lot. during covid, when attractions shut, ekasit and saebjoined hundreds of others in making the long journey back to surin, where institutions have been set up to give mahouts a salary and free veterinary care. being very careful. so what do you get from living here? in total, more than 3,000 elephants are put to work at tourist attractions around the country. charities say many are routinely mistreated. here, there's more peace, space and support for saeb, but ekasit is still chained to the floor. saeb says that it's too dangerous to remove ekasit�*s chains, due to his sheer size. ekasit is happy? you know, he's in the same place for a long time, but is he a happy elephant? saeb seems like such a nice person, who clearly loves his elephant, but, you know, so many people come here and pay to ride one through thejungle, or watch them paint, or even play football. now, many organisations warn against that, so the rule of thumb, they say, is to avoid any situation that involves an elephant performing for a paying customer. saeb told me that one of the main reasons he came here was because he can get treatment for his elephant. it looks a bit like a garage for elephants! they exchange greetings so which one of you is the vet? yeah. you're the vet. hi! nice to meet you. nice to meet you too. i'm lucy. i'm nat. great to meet you. i'm going to guess here. broken leg? yeah. yes. and is it hard for him to walk now? so a lot of the elephants that came in during covid, you know, have come from quite busy tourist cities, you know, some of them in quite inhumane conditions. what were some of the problems that they had? just before i leave, i wanted to go and see saeb bathe his elephant, a daily ritualfor him in his retirement. i can't help but feeljust a little conflicted. seeing them in chains really is quite hard to witness. some tour companies have stopped advertising trips involving interaction with elephants, saying the only ethical way to see them is in the wild. elephant rumbles i've never heard an elephant make that noise before! my final stop is almost as far north as you can go in thailand, just a couple of miles away from the border with myanmar. this range of hills is known as the sleeping princess because, from a distance, that's exactly what it looks like. i'm lucy. nice to meet you. really nice to meet you. so where are you from? i'm from pyau. pyau. up until a few years ago, there was no tourist shuttle bus in operation here. and this remote part of the world wasn't even a part of backpackers' trails. the industries here were all agricultural, so coffee, oranges, lychee, but things are changing. this summer, the tham luang cave system has been marking the fifth anniversary of a rescue that caught the world's attention. news report: 12 children and their football coach i who have been missing for ten days have been found alive in flooded caves. this is the biggest search and rescue operation in this country's history and i would imagine probably one of the biggest cave search and rescues there's ever been. the thai authorities are throwing everything at this. in the end, it took 18 days to find the wild boars football team and bring them all successfully to the surface. pictures of the dramatic operation were beamed all over the world. and now, people are coming to see where it happened, not least to lay flowers at the poignant new statue to saman gunan, the thai navy seal who lost his life during the mission. there's also a new museum, a gift shop and, for local people, the opportunity to make a few baht. how are you? are you good? do you get lots of tourists here? yeah? quite a lot? busy? you are allowed to explore the cave yourself, to a certain point, but i've asked two local caving guides to take me in a bit further. hi. hello. mario and taw worked here throughout the mission, installing the ropes and pulleys that winched the boys to safety. so what's it like being back in the cave? feels good. it's nice to be back. i love this cave. yeah. it's a really...pretty cave. lots of nice formations and, yeah... yeah, it's gorgeous. it's very quiet at the moment. during the rescue, so many people in here. a lot of noise. you were hearing the pumps. and people shouting around. carrying stuff in. yeah, i bet. oh, wow! this is where the medical team sat. medical team was over here, yes. the rescue was complex and dangerous. dive teams had to make their way through flooded tunnels, heavily sedate each boy one at a time to stop them panicking, and swim their unconscious bodies back through the system. so, tourists really aren't allowed through this part, if this gate is anything to go by. you only can pass this point with a guide and with special permission from the national park. so, is it normal for kids to use this as their playground? yeah, countryside. yeah. so, kids ride their bicycles, play football, come out, explore some caves. it's not the first time that they came in here. there were big pumps in here. yeah. to try to get the water out. yeah. how deep did it go? 60, 70. ok, so up to your knees, maybe. wow, that really hammers it home, doesn't it? we're getting into chamber two right now. two. chamber two is where all the high lines are in. 0h, 0k, yes. taw�*s team built this high line, which helped rescuers winch the boys back through the cave. yeah, to build a high line, it's a little bit tricky to build the anchor system here because, er... ..the rock at some spots is not really good. and, yeah, the day that the... ..the kids here... ..i'm crying, actually. yeah, yeah. yeah. i'm getting the impression things are going to get a bit trickierfrom here on in. you got me, taw! thank you! it is getting progressively tighter. and where i'm staring at right now, doesn't even look like people should go down there. but i think we're going to go down there! we call this one the keyhole. it looks like a keyhole over here. so, then, the (indistinct) team were over here, - to where you're sitting right now and then it had to be tilted a little bit to the side, to get... navigate through that. with the patient, with the kid, through the keyhole over here. and what was it like, you know, that moment when the first kid came through and you saw that and you got the thumbs up that they were alive? yeah. again, still, that silence, people didn't know what was going on. is the kid still alive or not? yeah, once we got the thumbs up, it was... yeah. ..feeling really good. as far as caves go, this one is very impressive. oh, it's like paradise. there's so many caves around. there's so much to explore. and we should preserve this one. yeah, absolutely. so, for us, it's very important that we leave no trace. everything we bring in, we bring out. we only leave footprints. and be respectful. be respectful, yeah. you know, i am genuinely blown away byjust how much respect these guys have for the nature here. and, you know, i think it's fair to say that thailand has quite a complicated relationship when it comes to its diverse landscapes and natural heritage, and, as a result, it has had to learn a few tough lessons along the way. and yet, there are efforts to persuade many more of us to come and see these wild spaces. the tricky part will be allowing that to happen, without destroying the very thing that makes thailand's environment so special. it's been roasting. and if this 20 recorded on friday as confirmed, that would be northern ireland's hottest september day on record —— 28. but turning cooler, heavy downpours as the change takes place, and on the earlier satellite picture, just the first sign of things changing. a frontal system setting up to the north—east which will start to briskly note the north—east of scotland as we go through the day on saturday. winds of prior permission from the south will provide some scattered showers, maybe the odd thunderstorm across western and northern parts. 33 in london could actually be the hottest day of this spell, and then through saturday afternoon, we could see some showers and storms popping up to east wales, then wouldn't come to pass of northern england. quick ball scattered but you will know about it if you catch on, a lot of rain in a short space of time, and more showers and storms speeding up from the south—west as we head through saturday night and into sunday morning. so we could see some heavy thundery showers at the great north run, and i think the good news for those taking part is that it is not it will not be as hot as it has been. so some scattered storms and —— scattered showers and thunderstorms through the day. still some heat holding on, 30 celsius for norwich and london, 21 for belfast, 22 for glasgow, and that is a sign of things to come, because as we head into the start of next week, these very warm orange because of these very warm orange because of the post with yellow and blue colours on our chat, something much cooler heading our way. as we have through monday, a frontal system are pushing southwards of the slits, outbreaks of rain, some showers, thunderstorms breaking out, quite a messy weather picture on monday, but all the while, the warmth will be squeezed towards the south—east corner and further north and west it will be turning cooler and fresher. through monday night and on into tuesday, showers and longer spells of rain, winds coming down from the north, some further heavy rain sitting at a northern parts of scotland, but even the subsumption, a much cooler and fresher feel, 15 celsius in aberdeen, 22 in london, so next week will be very different. the nights will be cool as well, tuesday night into wednesday could bring temperatures down to single digits, six celsius in glasgow. a far cry from the very warm and humid nights we have been having of late. wednesday looking pretty decent, some good spells of sunshine, our next frontal system or perhaps just starting to push him from the west, but still worth that much cooler feel, 13 to 20 celsius. these temperatures far closer to what you would expect at this time of year. so wednesday's fine weather brought by the seller of high pressure, but thatis by the seller of high pressure, but that is unlikely to last too long. it may be that we continue to draw some warm and into seven parts at times, but suddenly nothing as hot as we have seen of late. —— certainly nothing as hot. all live from london, this is bbc news. more than a thousand people are reported killed in a powerful earthquake in morocco, with hundreds more injured. police in london arrest escaped prisoner daniel khalife, following a four—day search. and world leaders at the g20 summit in delhi issue a joint declaration calling on all states to refrain from the threat or use of force. hello, i'm vishala sri—pathma. we start in morocco, where state tv says more than 1,000 people have been killed in the earthquake that struck late on friday night. hospitals in the region have seen an influx of wounded people, and the authorities are calling on residents to donate blood. the 6.8—magnitude quake struck in a remote area
