whistle. this is bbc news, the headlines: brazil's president, jair bolsonaro, has ordered the military to help fight the devastating fires in the amazon rainforest. several european leaders have said they are prepared to scrap a huge trade agreement with south america unless brazil takes action to curb the forest fires. president trump has announced further increases to trade tariffs against china. in a series of angry tweets, he said a planned 25% tax on billions of dollars of chinese goods would be increased to 30% from october. the move comes after beijing unveiled new duties on us goods. russia has launched the world's first floating nuclear power station in the arctic, in spite of concerns from environmentalists. it's now on a voyage to russia's far east. it's intended to supply power to oil rigs. spent fuel will be stored onboard.
artificial intelligence is transforming many sectors of the economy, and farming is one of them. it's hoped that precision farming will help to reduce waste and improve welfare, for example, using technology to track the mental health of livestock as well as their physical health and also helping to decide which crops are ready to harvest. our environment correspondent, claire marshall, takes a closer look at farming's future. what are these pigs thinking? how do they feel? this scanner acts as an eye for a machine that is analysing their expressions. soon, it should allow us to understand the pigs emotions. this technology, in its research phase, was conceived in the west country. the vision of the future of farming is one where the well—being of the animals and their comfort is the priority. just look at the facilities here.
the cow's movement is monitored to check its health. this tech is already on the market. the facial recognition is coming next. we will be able to see whether or not an animal that is lame, you can infer that it's going to be an unhappy animal, and whether that animal has a different face to an animal that isn't in pain. so we are looking to try to tease out those differences between the faces. here's another glimpse into the future. watch this disease spore. it enters a sensor biologically engineered to mimic the crop. like a kind of fire alarm, the sensor sets off an early alert. they can all be linked up, warning otherfarmers weeks before any damage is visible. and they can be sd printed. we've got some very clever, cutting edge engineering. but at the same time, there's cutting edge biology as well. and only by bringing those two together can we actually start
addressing what will need to be done in the future. 1.3 million broccoli plants are growing on this land near doncaster. we were given exclusive access to field trials of a scouting device that gathers data about each specific plant. it's the latest in precision farming. most of us as consumers, we don't buy wonky veg. if it's too big or too small or misshapen, the supermarkets won't accept it. we can know which plants are of saleable quality directly, and then if it's too small we can leave it behind and if it's just right we can harvest it. this could save millions of tonnes of food from being wasted and cut pesticide use. as the climate grows more unstable, scientists warn humans do need to take more care of the land. claire marshall, bbc news.
danger. it relies on the latest technology to better understand how to combat the flames. and if you want to be a firefighter, this is where you learn the craft. the international fire training centre in darlington, in the north of england. this is where brave firefighters come from around the world to learn the latest techniques in fighting all kinds of blazes. they can simulate a huge variety of fire scenarios here, oil rigs, industrialfires. that is an overturned fuel tanker, and they can
simulate any size of aircraft from the smallest to the largest. that is an airbus a380 and this is a boeing 747. and it is notjust about gearing up and grabbing the hose. every fire is different. and each needs to be treated intelligently to make sure you and the people you are trying to save have the best chance of survival. wow! my goodness. they are using the water as a protective shield. so it keeps the two fires apart, using the water. keeping the left—hand one at bay and then extinguishing the right one before we deal with the left. the centre tries to make each scenario as realistic as possible, not just the fire that the treatment of the casualties as well. it is fascinating to see the science behind firefighting. for example, in a kerosene fuel fighter, water will not put it out. this cone of water controls the blaze so another firefighter can come
in with a powder extinguisher. that is what finally tames the flames. and once they're gone, does that mean the job is done? well, that is where this thermal imaging camera comes in to see what our eyes cannot. so once it looks like the fire is out you still have to cover the area in waterjust in case there are hotspots. you can see here the vent on the top of this engine is still white hot according to this camera. and there are many other ways to detect and deal with fires. lara has been looking at some of them. for the past two years, half of the uk's fire brigades have been deploying these drones. they focus on the safety of firefighters and they are on board hd and thermal imaging cameras can provide much greater
visibility, which means a better understanding of a fire and the way that it is spreading. using a drone, we can get pretty much an instant overview of the entire fire in under five minutes and start moving our machines and our firefighters around just like chess pieces, really, all controlled by drone footage. it also brings us a massive benefit as we can see fires as they develop. the team here have also use them for rescues the team here have also use them for rescues and searching for missing people in quarries or in water. the hd camera is able to clearly zoom in on a face up to half a mile away. but of course when it comes to the spread of fires, what has happened recently in california is at the forefront of our mind. the university of westminster is researching a system that combines sensors on the ground and those in a drone. the aim: a solution for wildfire.
these solar—powered prototype sensors are tracking carbon dioxide, carbon monoxide, oxygen, humidity, temperature, gps and altitude. the aim is to combine them into one miniaturised cost effect if version which could be deployed en masse in areas susceptible to wildfires, providing immediate feedback. if there is something it will alert all their neighbours also, forming to a network, alert, take measurements, convey to the master node which then conveys it further up to the server which then alerts the drones to come up and get a visual. the plane comes with all the information that it has got from the drones, from the ground sensors and it knows what the windspeed is what wind direction is, what the temperature variation is did it it knows where the fire will be when the plane rendezvous is and then it makes a list from the air and then the heavens open as they hit the target whether fire is and you can fight fires day and night,
2a a day with no visibility. meanwhile, this is the stinger. it can pierce through metal and too much any roof, dramatically blasting foam or water into the heart of a blaze. the quantity and force of that water is pretty incredible. this pumps 1,000 litres a minute with an even more powerfuljet to the side, capable of 11.5 times that. it also has an on—board thermal imaging camera to assist with the precision. blackburn is currently the only uk fire service using this kit. i'm told it costs around £600,000. but maybe as costs drop
and this technology evolves, this next generation of firefighting will become the norm. i am at leicestershire fire and rescue, the first service in the country to invest in virtual reality. their hope is that money will be saved by replacing some of the expensive traditional training techniques with vr alternatives. i've seen the demo and the fire looks quite intense so i don't think it's going to be what i'm used to when it comes to virtual reality, which isjust having a nice time! let's see. all the scenes in the training are scanned from the real world. for instance, this arson hotspot in leicester is a good reference for investigators looking for clues. it's the inside of a destroyed smoke alarm.
ijust need to say, the environment is like i'm standing on ash. it feels very real. teleportation. oh, my gosh. there is a body down there. if you enjoy training, you get more out of it. it's already been proven by a study in the united states that if you train in a virtual reality environment, the retention rate is 75%. most of the talks i do on road safety, with powerpoint, we tend to make 5%. so you can see why we're looking at this because the training is going to be enhanced so much. if you want to skip10 seconds forward, you can do it on the controller and skip forward, so you can fast—forward fire again. you remember from the scene you saw a minute ago, that tv monitor was completely melted. and you can see how it physically affects thing that are not even burning yet. yes, and idea is as it stops,
we don't show the people putting out the fire, but you get the ability straightaway to dive back in the scene and now you're in that same burn scene. yeah, seeing the impact of that fire is pretty remarkable. it moves quickly. part of the reason this experience feels so intense is the realism behind it. for leicestershire fire and rescue, this was important, that they move away from gamification and into real life. they been working with a company called river to make this happen. the scenes are created using photogrammetry, both cameras and lasers photographing real—life 360—degree scenarios up to thousands of times. we've seen how fire services are using virtual reality, but what about other first responders? here at the defence science and technology laboratory, they are hard at work on how police might use virtual reality in theirtraining. number 7, ferguson house. caller report sounds a violent disturbance...
i can see already. i don't think people would expect to police and virtual reality together. why is it so important that the police are interacting with technology in this way? you can replicate one—off events so a one—off event which could be a dangerous or hazardous environment, you can actually recreate one—off and people would never, ever get the opportunity to rehearse that but in vr, we can, so we can give them that vehicle, give them that opportunity to do a one—off scenario and do it safely. oh, my gosh. 0k. i'm going to see if this woman is alive. she's obviously taken some pills. there is a heartbeat here. i can definitely see already how it would be used, in a way that a lot of games are, really, to open up your mind to possibilities around crime, why people may have committed criminal activities,
