this is bbc news, the headlines: president biden has signed into law the biggest ever investment to fight climate change in the us. the bill includes more than £340 billion of new spending and provides tax credits for people to install heat pumps or buy electric cars. voters in the us state of wyoming are expected to oust liz cheney from her seat in congress in republican primaries taking place. the three—term congresswoman has been one of the most vocal critics of donald trump, who's backed a rival candidate, harriet hageman. russia is blaming what it calls "sabotage" for a series of explosions at an arms store and another military facility in occupied crimea, a week after explosions destroyed russian warplanes

on the crimean coast. ukraine has hinted that it was behind the latest incident now on bbc news, return of the tigers. tigers are making a remarkable comeback here in nepal. their numbers more than doubling in the last ten years. tigers are the majestic creatures. being assigned in the protection duties, it's an honour, you know, it's a privilege. it's a small victory in a battle to bring them back from the brink of extinction. it is definitely something to be celebrated. it does not come without the cost. the common area that the tiger and prey species and humanity shares is so tight,

the community lives in terror. there has been an increase in tiger attacks on humans. more number of tigers and more number of people, definitely there is going to be conflict. so, it is going to be a challenging job for us to, you know, maintain peace between two species.

chanting private pinky adhikari has been newly stationed at bardiya national park in western nepal. herjob here is to protect the park's endangered elephants, rhinos and tigers. after morning exercise, her unit heads off on patrol.

we've been given rare access to go with them. one of the key factors of nepal's success has been strong enforcement against poaching and that's involved the military. armed units like this one patrol across the park daily. her unit's captain is ayushjung bahadur rana. tigers are the majestic creatures. there are two types of feeling when you come in head to head with them. it is "oh my god, what a majestic creature is that!"

and the otherfeeling is "oh my god, am i dead?" so, that's the type of feeling you get when you encounter when you encounter a tiger. so, being assigned in the protection duties, it's an honour. it's a privilege to be part of something that is really big, you know. so, what are you looking for on this patrol? i mean, like, we're looking for any illegal encroachment of people or domestic animals. these are the basic things that we look at while we're on patrol. do you have the power to shoot? only — only if we have any life—threatening encounters with the wild animals or it is the poachers. but that is the last resort. that is the last thing we would want to do. just outside the national park, indigenous leader bhadai tharu patrols his community forest. it's part of a key corridor that allows tigers to move between protected areas

in nepal and neighbouring india. this used to be a grazing area for cattle but was reforested by bhadai's community. he was cutting grass here in the forest with over 100 other people when a tiger attacked.

he lost his left eye.

he sings this whole area used to be a royal hunting ground. newsreel: this is a land whose people have always lived underl the menace of marauding tigers. when queen elizabeth visited the country in 1961, she took part in a tiger hunt. newsreel: and, yes, there was a tiger. - king mahendra had fulfilled

a time honoured obligation of a host in nepal and provided the royal party with a tiger to shoot. but there was more hunting to come. the next prey was a rhino. the rhino was also killed. hunting, poaching, and habitat loss has pushed tigers towards extinction. and that was the end of another animal. since the beginning of the 20th century, their numbers globally have dropped by more than 95%. but here in nepal there are signs of a remarkable recovery. the rangers are taking part in a nationwide tiger census. over 800 camera pairs have been hidden across the park. you just installed this camera.

how long will you keep it here for? so you are going to be having over 1,000 hours of footage look at? and when you're analysing the footage, how do you make sure that your count is accurate? with fewer than 4,000 wild tigers left in the world, every tiger counts. the census results show that tiger numbers here in nepal have more than doubled

in the last ten years. the area where tigers were once hunted is now being managed so that they can recover and thrive. this grassland is cut and burnt and there's man—made waterholes here. it's to attract the deer, the tigers�* main prey. before this area became a national park there was a village here. bishnu shrestra is the chief warden of bardiya national park. it's a better environment for tigers. yes, yes. more spaces, more tiger numbers. and you're also looking at water sources, increasing water sources across the national park.

yes. until now we have created 180 water ponds here. 50 water pond is with solar. is there a chance that with these interventions that you're pushing the tiger population beyond what's sustainable for the size of the park? no. we are creating many water pond and grassland, particularly for the prey species and the tiger. we have sufficient space and prey density in the park, so we are managing the tigers in a sustainable way. that evening we see signs of the return of the tiger close to where we're sleeping. just behind our camp, fresh tiger footprints have been found in the sand here. we think they are from an adult female tiger — we saw a lot of deer last night on the grassland and there's water here, so the footprints in the sand here lead

all the way to the water. this camp is run by conservationist manoj gautam. it is definitely something to be celebrated. it does not come without a cost. and it has been costing the lives of people and so much more. the common area that the tigers and prey species and humanity shares is so tight. we head out into the villages just outside the park's boundaries, into the communities that live with the tigers. here in these villages, the lives of humans and tigers are intertwined.

some in the community live off the tourism industry that's built around the park. others have to take the risk of entering the jungle for their livelihood. samjhana lost her mother—in—law in a tiger attack last year. she was deep inside the national park, cutting grass for their cow. samjhana heard the story from those who were there.

the government pays around us$8,000 in compensation to tiger victims�* families. but because samjhana's mother—in—law was inside the national park, she has been told she doesn't qualify for it. she is still fighting for some kind of financial help to put towards her boys' education. this is the tiger that is believed to have killed her mother—in—law and two other people. now behind bars

in kathmandu zoo. right now the national park is actively trying to increase the tiger population, how do you feel about that? protests broke out injune after a leopard attacked villagers, a week after a woman was killed by a tiger. the community demanding authorities do more to protect them.

the protests turned violent. police opened fire on the crowd, killing an 18—year—old girl and injuring others, sparking further outrage. the community lives in terror. so, there is a price that the community has paid for the world to rejoice with the news that nepal has successfully doubled its tiger numbers. when a tiger kills a human, authorities track them down and take them captive. 16 people have been killed by a tiger in nepal in the last 12 months. one of the tigers now in captivity is being held behind the chief warden�*s office. this tiger killed one human in the last year in the rajipur

area, so we captured and kept in this tiger holding cage. how do you know it's the right tiger? we closely monitor through camera in the incident area, after identification, we captured and put it in holding cage. do you do that because there is pressure from the community? or is there a real threat that once a tiger has killed a human, that they will attack again? there is a chance to attack the human again, by the tiger, if the tiger killed one person previously. so, this tiger has been here for one year now, you can see it's not happy about being in captivity. what is the long—term plan for this tiger? we have ordered a satellite collar for this tiger. after consultation with our department we will do something regarding his release.

bhadai tharu calls a meeting of his community protection unit. this is a generation that will have to navigate the return of the tigers. susila, who is also part

of the community protection unit, runs this after—school class. susila also worked as a tour guide in the national park. you have to see tigers in the wild to fully appreciate them, she says. so, we head back into

the park together. i'm looking for tiger and leopard, this is the track that they will come to the river to drink. and sometimes we get also elephant. susila takes us to a spot near the river. and after hours of waiting, a tiger suddenly appears. it is magnificent to see a male tiger walking along here, one of over 100 tigers now here in bardiya national park, part of a growing tiger population here in nepal. it is definitely something to be celebrated, because as we know everywhere around the world, the conservation stories that we often get to read are loudly depressing,

and the number of species we are losing on a daily basis, the habitat loss that we see every day. and nepal brings a freshness to the arena of conservation. music and chanting. they have participated in this, they have rejoiced in the success as well, and they are paying with their lives and terror, and that i think needs to be acknowledged more. because if it is not acknowledged, the world cannot come together to find a solution for that. despite what happened to her mother—in—law, samjhana continues to risk entering the national park. for the soldiers, the challenge

is to keep the peace. we are the mediators, so it's our duty to bring peace between two species. and so it's the both — i would say the protection of the tiger is our responsibility, but at the same time protection of civilians is also our main responsibility.

hello there. a north—south divide across the country today. northern areas looked largely dry with plenty of sunshine, but again, across england and wales, closer to a thundery low than we're likely to see these thundery showers developing. again, they could be heavy enough to cause some localised flooding, especially from the midlands southwards. you can see that thundery low to the south, a ridge of high pressure building in across the north. this weather system will arrive across northern and western areas on thursday. so again, for large parts of england and wales, we'll see the clouds bubbling up, thunderstorms breaking out pretty much anywhere, but certainly across the midlands, in towards south, southeast england. further north, widespread sunshine around, light winds too. a very pleasant day, with temperatures reaching around 18 or 19 degrees, england and wales.

little bit cooler, still quite humid in the southeast, top temperatures 20—23 degrees. as we move through wednesday night, the showers and thunderstorms continue to rattle on across to east anglia and the southeast. and then eventually, they'll clear away and we start to see some wetter weather and breezier weather pushing into scotland and northern ireland, so temperatures recovering here. a few chilly spots under the clear skies, northern england, 11—15 across the south and east. here's thursday's pressure picture, then. this weather front bringing outbreaks of rain into scotland, northern ireland, perhaps western england and wales through the day. some heavy bursts mixed in there, quite a lot of cloud, generally. across the east and southeast of england, though, apart from the odd shower around, we should see some good spells of sunshine, so a quieter story here. a little bit warmer with more sunshine in the southeast, up to 25 degrees. around 20 or 21 as well across scotland and northern ireland. into friday, looks like that weather front eventually clears away from the southeast of england. we've got further sunshine and showers, scotland and northern ireland,

northwest england, but quite a bit of sunshine, i think, across central, southern and eastern england. and again, quite warm — 25 degrees. around the high teens in the north and the west, these sorts of values closer to the seasonal norm. we hold onto the run of westerly winds as we head into the weekend, this feature bringing an area of wet and windy weather across scotland. as we move through saturday night into sunday, though, we'll look at the next system, which will bring a spell of wet and windy weather across the whole of the uk during sunday. so for saturday, then, it looks like it's northern areas which will see the showers. drier further south. sunday, though, looks unsettled across the whole of the uk, with outbreaks of heavy rain in places.
