sunni's from spain where the prime minister petra sanchez is called early elections for april after losing a key vote a spending plans put forward by sanchez's minority socialist government were voted down by lawmakers earlier this week including members of the two main catalan pro independence parties the snap poll on april twenty eighth will be spain's third election in four years it's been your baby can do what i want from spain must continue to advance and progress from a point of tolerance and respect from moderation and common sense excluding politics from frustration growing and creating quality employment redistributing wealth consolidating and recognizing not just the rights and liberties we gained in the last forty years but also expanding the perimeter of those rights and liberties strengthening social cohesion and territorial cohesion as the only guarantee that we preserve spains unity for this i announced to you with the powers given to me as prime minister of spain and after consultation with the council of ministers what i

proposed dissolving the chamber of parliament and the complication of general elections are twenty eighth of april. without is there a lie from london more still ahead for you on the program a saudi crown prince heads to pakistan where he's expecting a warm welcome and is likely to offer billions of dollars in investment and an uneasy calm in haiti where the president is refusing to step down despite weeks of anti-government demonstrations. hala because some of the lovely weather across central and western parts of here big area of high pressure keeping it nice and settled clear skies and some pleasant sunshine in the sun does have some mates about it at the moment so we can have to thirteen celsius in london and passion about. i tell my degrees at this time of

year so we are certainly on the mild side there's a fifth day in there for madrid again with some sunshine central areas well i just see one or two folk patches think a cloud over its will see eastern side if you must go two degrees celsius even that is on the mild side not just in town and right into the eastern side of the med that will continue through sunday although it will brighten up for a good part of greece at that stays stay dry and fight across central and western parts of london and paris could touch forty degrees to move into the second half of the weekend but cloud and rain will make its way across all and into wells western side of scotland much of england will be fine and dry forty celsius for london fourteen celsius for madrid as well come down into an all impossible because a fourth same for tripoli quite a pleasant cloud some bits and pieces of rain there just scraping the fall north of libya pushing over towards egypt little cloud also making its way across morocco that will sit across a good part of algeria algiers with a top temperature of eighteen degrees.

talk to their own. you personally one of the main beneficiaries is that the case listen if you want relations with india all that's was exactly my point we meet with global newsmakers and talk about the stories that matter.

a comeback but look at top stories this hour u.s. president donald trump says he will sign a national emergency to access funds for a border war with mexico the president made the statement after approving a spending bill to avert another government shutdown venezuela's president has accused the united states of trying to be stabilize his country in an interview with al-jazeera nicolas maduro also criticized european nations accusing them of supporting u.s. military intervention. and memorials have been held for at least forty four indian security forces who were attacked who were killed in an attack in indian controlled kashmir prime minister narendra modi is by in pakistan for backing the assault crushing response. in other news turkish president says the cia hasn't put its full weight behind the investigation into the murder of jamal khashoggi saudi journalist was killed in the country's consulate in istanbul last october out on has told turkish media that his officials still haven't received all the documents relating

to the case that he expects it to be had by an international court saudi crown prince mohammed bin soundman has been accused of ordering the killing riyadh denies any involvement meanwhile the crown prince is embarking on a tour of asia and will be his first visit to the region since the fallout of the show g.'s matta france's first stop is pakistan where he's expected to sign an investment package is russia going to him explains pakistan is planning a royal welcome for saudi arabia's crown prince mohammed bin selman pakistan and saudi arabia have long been allies but this is the first visit for the crown prince since he became heir to the throne. put on a both but they are our old friends and their policies are in favor of pakistan. they will increase their wealth by investing in pakistan this is useless for our people. prime minister imran khan wants to make a good impression. is looking to. one is that bit of

pick apart is called mint and the country konami quite a second is foreign direct investment cons overture comes as much of the world has either shunned criticized or chosen to keep an arm's length from the crown prince both turkish and american security agencies have concluded that mohamed bin salmen ordered the murder of washington post columnist jamal khashoggi the veteran journalist was killed and dismembered inside the saudi consulate in istanbul last october cond just two months into his tenure never joined the global chorus of outrage against the kingdom and the prince. later that month he was one of a few leaders to attend a financial summit in saudi arabia a pet project of bin solomon intended to elevate the country's image and promote foreign investment there would be no political cost for him to muster could put him

at the moment it's not important what's the word thinking the crown prince plans to show his appreciation by injecting billions of dollars into pakistan's economy. since the nine eleven attacks pakistan has been viewed as a vital player in combat ing armed groups and maintaining regional security but overlooked when it comes to foreign investment prime minister khan is banking on the fact that were saudi money is invested other countries might follow natasha can aim al-jazeera. we go to haiti now where the president. is refusing to step down this despite weeks of anti-government demonstrations at least eight people have died in that on rest which which was sparked over rising prices and government corruption and as. are apollo reports from the capital port au prince opposition leaders saying they will continue to call for more uses resignation.

tensions on the streets of port au prince are back on the rise many fears of violence just gripped the country for more than a week could begin again at any moment the anger here stems from a government audit which discovered more than two billion dollars in development funds are unaccounted for the money question was part of the oil assistance program called the. defense highway if one comes from. former president hugo chavez who wanted to have self self. we've. but what happened. in spending that money and. all those project that they were supposed to realize they didn't realize the evidence of mismanaged funds can be seen across the country in unfinished infrastructure projects like this half built overpass even renovation the national parliament building a multi-million dollar effort financed in part with bit to get even money is still

far from completed more than seven years since construction began. making his first public appearance since the protests started on february seventh president condemned the violence on the streets but didn't outline any steps toward finding a resolution today and aid to the haitian president says the flames of the discontent are being fanned by the president's political opponents. ation politicians always want to get rid of the president after a year or two that's why we have this chronic instability the president wants and he's open to have a frank dialogue. what the latest protests in haiti are linked to the bad look at even scandal discontent with the government has been mounting since the aftermath of the two thousand and ten earthquake where more than one hundred thousand people were killed with widespread poverty a declining economy and new evidence of systemic corruption and you're finally

reached a boiling point on the streets of the haitian capital we're in downtown. the prince where there is in an easy calm as people pick up the pieces after more than a week of protests there are still roadblocks set up that are preventing the free flow of traffic and the tension that seems to suggest that the unrest may not be over just yet anti-government demonstrators have renewed calls for more protests continuing to demand the resignation of the president a condition that moyes has made no indication of accepting the more moderate figures of the opposition are calling for a national dialogue one that includes voices from all sectors of haitian society however remains to be seen both sides will be able to find a lasting resolution to the ongoing political crisis went up a little dizzy to port au prince. a south african businessman i.j. has had his arrest warrant cancelled he was wanted for allegedly offering bribes in two thousand and fifteen minutes past the infamous south african family cues that

having had a corrupt relationship with then president jacob zuma has more now from johannesburg . south african police have cancelled an arrest warrant for indian businessmen and jacob was issued nearly a year ago for corruption charges and his two brothers are accused of collaborating with former president jacob zuma and his family to steal hundreds of millions of dollars of south african public money things that the book has and zuma deny south africans waited for years to see people being held to account for the corruption scandals of the zuma years and many here will be disappointed if they don't ultimately see people in court or people in jail they're also waiting to see if things would change since president several run opposer took over from zuma about a year ago prosecutors say investigations are ongoing and it's possible that by dropping the arrest warrant now they'll buy themselves more time to complete investigations which is still happening ultimately leading to

a long list of charges against those who were implicated. nigerians elect a new president on saturday along with four hundred federal legislators youth unemployment rising inflation and violence are just some of the main issues for voters and more than three hundred thousand security staff have been deployed to keep the public safe i mean interest reports from the northeastern city of my degree. after a long heated campaign season nigerians are set to vote election materials have reached one hundred twenty thousand polling stations where eighty four million bridges to voters will elect a president from a list of seventy three candidates we have already received all the logistic items we have received all the nastiest sensitive items we have received the sensitive items and the ballot boxes the ballot papers and the rest of them

and we have already identified. the vote comes as the country struggles with the same issues that have dominated its politics for years decades of mismanagement and large scale looting of the treasury forced the economy into its worst recession in two thousand and sixteen it has since emerged from the slump but growth is sluggish there is the need to encourage the growth of the economy to expand you know the capacity of the economy to absorb the excess. labor force that we have so all that. it's a key challenge. the country's largest voting bloc is the one worst hit by the lack of jobs on most one in four of the country's youth is unemployed lack of them let me sort of i want to. exaggerate the. traits of our own

flowchart for being so even if it's about him being a mug shot it's a benefit everybody the potential to give up the empty promises all the you know all the time so all this time around i want them to be accountable for whatever d.c.d. . but the biggest threat to the country is security from the armed group to communal violence and clashes between farmers and herders tens of thousands of nigerians have been killed in the last decade the long queues at petrol stations that nigeria became renowned for in previous years may have largely disappeared but africa's largest producer is still not refining enough for domestic consumption nigeria's the education sector has not fared any better over the last few years while basic education is neglected by most state government university education continue to suffer from lack of adequate funding this university one of the largest

in nigeria is yet to receive michael dimock activities after three months nationwide strike. we have emerges us president in this election will be dealing with these and many other challenges that some nigerians say previous leaders of either deliberately failed or lack the capacity to tackle. greece al-jazeera. nigeria. two men have been sentenced to death in myanmar for the murder of a prominent lawyer and close adviser to head of government unsung suchi men were found guilty of killing cohen ayat young on at force in two thousand and seventeen two other men received prison sentences when i was working on reforms aimed at challenging the military's grip on power is death was a setback for sue cheese government which has promised changes after decades of military rule. but it's a showcase for the best in british fashion started with big names like

president donald trump says he will declare a national emergency to access funds for a border war with mexico president made the statement after approving a spending bill to avert another government shutdown by using emergency powers trump will bypass congress which has refused to approve nearly six billion dollars needed for the project we're going to be signing today and registry national emergency and it's a great thing to do because we have an invasion of drugs invasion of gangs invasion of people and it's not acceptable and as well as president has accused the u.s. of trying to destabilize his country in an interview with al jazeera nicolas maduro also criticized european nations accusing them of supporting u.s. military intervention meanwhile washington has imposed financial sanctions on five officials close to a duo including the oil minister. memorials have been held for at least forty four

health i'm going to keep going morgan parktown there's no more that feel good hard . on al-jazeera. this is techno innovations that can change lives the science of fighting the fire we're going to explore the intersection of hardware and humanity and we're doing it in the unique way. this is a show about science low turnout by scientists.

tonight. techno in search of the great american prairie where in the current state yet ironically we have such little of it left farming and over development killed it now get ready for this explosion of color and the return of these native animals how many fat species do you have in here but volunteers trying to bring back one of the planet's most complex ecosystems ran into trouble we just needed something that help to level the playing field why a certain animal from america's past was needed to pull off the impossible they've just arrived at the grassland and i'm seeing these bison for the first time marie to davison is an environmental biologist tonight a trip to the heartland always a baby. deer a santa maria is a new scientist from i'm phil tourism i'm an entomologist the epic drought of twenty fifteen takes

a hidden toll. from above these trees may look green and healthy they're not here we see something that's dramatically different now the technology that can see we can't that's our team i'm a prairie fire now let's do some sun it's. hey guys welcome to techno on felt toys joined by cara santa maria maria to davison and say we're going to talk to environmental stories and to start off the great american. to me it's one of those iconic images of how the us used to be unfortunately now it's almost entirely just a part of our history yeah there's been a lot of over development of farming and a suburban explosion that's really taken a toll on a lot of prayer ecosystems illinois has been extremely hard hit it's changing but there's been

a big change in the landscape there and this is happening across the united states but i got to say what i really love about this story is that there's a bit of us west so there is i want to give anything away so let's go about ninety miles outside of chicago where they're bringing back a little piece of history it's kind of a big piece of history ok a big piece of history to go on. you're looking at a thirty five hundred acre experiment in a growing field is known as restoration ecology. this is the new choose the grasslands preserve in franklin grove illinois ninety miles west of chicago where the nature conservancy is rolling back time two hundred years to restore a tall grass prarie that was almost extinct. were in the curry state yeah ironically we have such little of it left at the time of

european settlement about two thirds of the state some twenty twenty five million acres in the state was tall grass curry we have less than one one hundredth of one percent of the native curry but still intact. the mission is being overseen by three illinois and natives jeff walk director of science for the nature conservancy project director bill kleiman. and restoration ecologist cody considine. it was a vast landscape dominated by those grasses but the real diversity of the prairie was in the wild flowers the forms the broadly plants and thousands of species of insects and dozens of birds and mammals and reptiles called the prairie home along with animals like the bison. what was once this vast landscape across much of illinois has been virtually eliminated and turned into the corn belt. but illinois isn't alone since the late one thousand nine hundred sprit grasslands across the united states have been steadily vanishing. i've heard grasslands and

general referred to as the unheralded counterparts of the rain forest and grasslands have a critical role in terms of climate change as well in a prairie most of that carbon is stored in the soil and so it's very secure for very long term storage a soil organic matter in essence the plants of the tall grass prarie absorb carbon dioxide trapping it in their deep roots. the restoration began in one thousand nine hundred six growing from a small plot of remnant prairie land that had never been farmed. and starting with fire the process hasn't changed much in thirty years. it's completely fire dependent without fire we could not have pretty good vegetation grows more vigorously and most species of plants have a season of more intense blooming right after a few the first year of the second year after the fire no one knows that transition

better than restoration ecologist cody considine. gray we're standing in what looks to me at least two very different types of areas what happened here so yes or right in the line of two different prairie restorations the one right here was planted two years ago and the one behind us was planted the three years ago so overseeing is as easy prey restorations. get older more plants emerge they get more mature they're flowering so they're quite dynamic how many plant species do you have in here for this particular flight and i believe we had one hundred thirty species ranging from here's a native western sunflower this is a coral species we have rattlesnake master here we have grassley of goldenrod here is an american a show here a paper book on foot already flour. all those bloomers started here all right so this is the seed room. project director bill kleiman well you might think

that the prairie stude would find its way out into these former cornfields but it doesn't walk very fast so we would have to wait millennia whereas we can collect a scene from the remnant prairie and bring it out to a cornfield that we're retiring planted and it'll grow back year do you have a sense of how many see you in the volunteers here have planted over the years about two hundred fifty species a year so it's it's millions and millions of sea. conventional wisdom was to plant ten pounds of seeds breaker but bill ordered fifty pounds and the fields blossomed none of that would be possible without a core of volunteers like jay stacey. so what are you cutting today this particular four bit is called perth coreopsis scientific name coreopsis pomade how long have you been doing this i've been doing this is my twenty first year.

i'm a prairie bar where. all the tall grass planting was a little too successful. we just needed something that help to level the playing field. what they needed was something to thin out the grass. like an enormous vacuum this. lucian not a dyson but a herd of bison. a posse of eight hundred pound grazing machines. we've just arrived at the grassland and i'm seeing these bison for the first time and i feel like i've just been transported back one hundred fifty two hundred years it's it's pretty it's pretty remarkable to see these enormous animals that were almost wiped out from north america all there's a baby there's a little one oh a couple of. bison have been part of the vision for the project since the very

beginning but it's taken us close to thirty years to be able to put together enough of a landscape where it was a practical consideration for us. and . these iconic bison are the missing link for a massive restoration of this endangered tall grass prairie run by the nature conservancy. would you say that they have been a game changing factor here. in these animals are going to make a difference on this prairie and. i hitched a ride with misuse of project director bill kleiman and restoration ecologist cody considine to track down the bison in their five hundred acre grazing area. why are the bison so important to the restoration process bison ate grass

and there the disturbances they're creating puts diversity on the landscape as they graze the nutrients are going in one of them is coming out the back and you're getting a very quick nutrient cycling on the prairie. those bison patties are spreading seeds and fertilizing the soil what's the average weight of a full size. bison the coyotes can range from eight hundred to eleven hundred pounds in the balls as they mature they can get up to two thousand pounds massive so how many bison do we have on them on the reserve thirty adults and sixteen calves the calf was just born last week a little tiny want to get easily pick it up it's pretty exciting to think about the calf being born a illinois prairie that hasn't happened for probably two hundred years. what happened to bison here there was a tremendous slaughter of bison in the eight hundred seventy thousand eight hundred eighty s. . just walk is the chief scientist for the illinois chapter of the nature conservancy

. as estimated by the turn of the one thousand hundreds there were probably four hundred to one thousand animals that had persisted out of that massive herd of thirty to sixty million is close to extinction it's absolutely closely extinction there was definitely a market for the hides for the meats also part of it is that it was encouraged by the u.s. government as a strategy to help reduce the food supply for the native americans in the conflict with the native american peoples it's estimated there are about four hundred thousand bison now in north america. but most of those mice and we're bred with cattle for meat production only about twenty thousand are pure american bison. that genetic line dates back to nine hundred thirteen when fourteen bison from the bronx zoo were trucked to win national park in south dakota at the behest of teddy roosevelt. so when it was time to bring

bison to choose they looked for a posse with the wind lineage. going. we went to broken code on grassland another nature conservancy preserve in northwestern iowa in october of twenty four team and brought back twenty animals with us we were essentially separated off the animals. we were going to bring back to illinois make sure that they were out of a clean bill of health. seven of the females we strapped g.p.s. collars onto so that we can get your real time movements of the animals tracking those movements with the g.p.s. collars is julio brockman a bison researcher at southern illinois university. what kind of data are you receiving so we're getting location information a g.p.s. point on a map every hour twenty four hours a day so can you show me what you've been seeing sure these are the bison locations

for yesterday they seem to be spending a lot of time along their corral and trap pressure and i can corroborate that because we were there and we saw them there so what would you say is the ultimate goal of your study having an amount of data really changes how we look at their movements and their selection it helps to understand what type of habitat they're like for reintroductions in the future. among the two dozen scientists doing research at the choose is dr holly jones a conservation biologist at northern illinois university with her team she's traveling in tagging small mammals to assess the impact of the big bison. the completely restoration ecologist playground i get so excited about this field say let's see if some of the men. there it is small mammals or food for aerial predators things like hawks things like owls and so it's really important to know how they're doing to be able to say how the person doing as

a whole and that's because if the small mammals are tasty enough to become good prey they're feasting on a healthy environment of insects and plants. what do you see since bison have been introduced we've had thirteen lying around the world which was very surprising the line of evidence pointing towards a shift in community compositions and there are different. plots of land that have been restored at different times all the way back to twenty years ago we can look at a plot of land like this that was restored four years ago and we're going to part of land over there that was restored six years ago and one sees and look at how restoration progresses. how we think improves science and some way. you can but you can go there. less than a year since the bisons arrival the environmental impact is subtle some changes to plant growth and small animal populations but the biggest change may be on humans.

for a very connected to this herd they still feel like these are their bodies and this is such a cool thing that we've returned this iconic mammal to illinois it's exciting. i got to say i love when you guys bring stuff back from the field especially from someplace as iconic as tall grass per summery what did you bring us at first till you got to stand up ok i'll tell you are about six two ok so here is a tall grass from the tall grass prayer that is some tall grass stalk i mean i was literally swimming in this stuff you know this is amazing this is part of the vegetation we're taught in this is what the bison munch on this is that's exactly what they munch on this is what the bison were brought in to help control the good news. now these are little seed pods they look like musical instruments but they're seed pods of some of the vegetation on the prairie that

a nice little rain to get and this is what they've been using to replant some of the native vegetation and then where this is the last piece of the puzzle this is a bison ferment. that surprisingly soft yet and you can see there's stuff in there is a lot of stuff in here so you can see really easily how bison would be dispersing you know these. these little seed will these large sea disperse years across the prairie or does even come to shave like a bushel when i was looking at that footage i was blown away by the color in the prairie the biodiversity the flowering plants and i wonder if a lot of people have that preconceived notion that nothing grows that they would if i told you kara that along with tropical rain forests prairie lands and other grasslands are the most biodiverse complex ecosystems in the world would you believe me. i mean i believe you because you are an expert it's not it's totally true but it does hold my mind and i thought it was really interesting to learn how

important the prairie land is here in america for you know the speak like that change problem that we're all facing these these grasses and these different plants actually act as a kind of a carbon sink don't they they really do the bulk of the plants in the prairie are not above ground they're underground because that's how they survive fire they actually are a big factor in storing carbon yeah and that really does feed into the very next story marine until you guys tag teamed a little bit right both from this guy and from the ground i got to see california forests from an airplane like no other and while you were in your flying laboratory i was on the ground seeing the reality of trees and what's taken him down. is so epic it's so of the norm that we actually don't have the answer to what can we expect long term california's epic drone. reservoirs are near empty

farmers' herding and it's forests are aflame or under attack by opportunistic casts so we're seeing tree mortality all over the landscape but in order to understand these changes to forests scientists must first assess their health using field officers and airplanes we have the most advanced airborne remote sensing package that i know of on earth today for over a decade ecologist greg as noor has been monitoring the health of forests around the world in an aircraft called the carnegie airborne observatory techno profiled his work mapping the amazon in a previous episode this time we joined him on his latest effort to map drought plagued california forests in his tricked out door need to twenty eight. in the back of the aircraft are unique sensors designed to take measurements of the forest canopy while the plane flies over it we're flying over about eight million trees per hour one of these instruments is known as light our this instrument is

a laser system that fires two lasers out of the bottom of the plane in a pattern that image is the forest canopy over it ever it is that we fly over in three d. what the instruments do is provide us a very accurate very unique way of understanding the amount of carbon stored in california's forests if you don't put carbon in forests then it ends up in the atmosphere and that contributes to climate change the plane is also equipped with a pair of spectrometers used to detect the chemical composition of trees it was time for takeoff where we going today today we're heading out pretty close to the oregon border where we have a lot of force that's unknown in terms of its drought stress and with that we were off from the air we could see reservoirs in rivers clearly depleted of water lake shasta reservoir that's where it's a lot of water policy when you see walk approach but the forest canopy actually looks pretty green but the big. it looks like they're pretty good shape. for his

course. throughout stress today by. this is that most of these were. in trouble back at the lab as there's team got to work analyzing all the data that's where techno still torres picks up the story see you did a flight with merida these are the results and looking at the cockpit it looked green but here we see something that's to radically different and what you see we see that the forest is varies from what we would consider pretty average conditions in the yellows and blues up there down to areas that looks severely drought stricken in red next we looked at an area where the drought stress was more acute so this is from los padres national forest this is what it looks like when you fly over gray green looks like your typical southern cal forest. this is what it looks like in chemical detail those trees are doing ok but everything else that

is showing severe drought stress and that's showing here in red now that we have the view from above we decided to head out for a boots on the ground perspective i'm standing here in the middle of los padres national forest and as you could tell from all the dead trees behind me there's plenty of evidence of the impact of a multi-year drought one of the biggest problems here a bug that attacks water stressed pine trees. and now we're talkin hours a bunch of tom coleman is an entomologist with the u.s. forest service a lot of dead trees right here yeah this is a nice will active spot bark beautiful. bark beetles kill more trees than any other kind of insect or disease in north america when you just look across the landscape and you see this kind of patchwork of dead trees mortality is quite dramatic this tree here is full of thousands of bark beetles does that mean that all the trees around here are now susceptible right. from what i've seen it's just

basically across the entire landscape have you ever seen this but not here in california. so just ten minutes where we're looking at the devastation caused by the pine beetles and now we're here and you can see the damage done by forest fires and there's a lot going on here so even though the wildfires actually gone through an area and cause major mortality it will still see bark beetles coming in afterwards scientists studying our forest are concerned about the impacts from drought not just in california but also around the world now what we're starting to worry about is whether these droughts are somehow all interrelated in length at a global scale to suit a lot of force of the world or in trouble droughts putting pressure we don't know exactly how much of the global forest cover is at risk but we're in the process now

of finally getting the measurements we need to make those predictions. the scientists that are studying these things they can say here's the problem but their hands are tied they all they can do is wait for the drought to be over for el nino to pass and try to influence management and policy they need to get the data into the right hands i think that's the plan that has to get into the hands of managers and decision makers so that they can actually implement changes and whether we're talking about managing america's grasslands or america's forest and one thing is for certain that if we have healthy ecosystems we will eventually have a healthier climate absolutely and thank you for the story today guys know from prairie being restored by bison to forest being decimated by beetles one thing's for sure it's a complex ecosystem out there but there's a lot of scientists working hard on it that's it for now we'll see you next on your own techno dive deep into these stories and go behind the scenes at al-jazeera dot
