blockade of yemen is catastrophic and along with the international with international aid groups is calling on riyadh to lift it fuel prices in yemen have increased by more than sixty percent cooking gas prices have doubled as well after saudi arabia cut all aid access to the country in our other headlines donald trump as north korea to make a deal to end the standoff over its nuclear program the u.s. president is in seoul on the second stop of his tour of asia and has held talks with south korea's president lungi in trump who recently said the time for talking was over has also said he's still open to negotiations with pyongyang it's been reported that the shooter who killed twenty six people a church in the u.s. on sunday that escaped a mental health facility five years ago devon kelly had been sent there for beating his wife and his stepson before mccaslin president carter's push to mount is made his first public appearance in brussels since spain issued an arrest warrant for
him there are signs the procession camp are focusing less on independence and more now on regaining their autonomy from spain you're up to date with all of our top stories that's it for myself and the team in london earthrise is next. it's u.s. president donald trump visit to asia. to forge relations and strengthen the resolve to confront the threat from north korea but what impact could this visit really have we'll be live across asia to bring you the very latest coverage on al-jazeera .
some people don't have to worry about where the next meal comes from. but these food supplies weren't always be so reliable. eight hundred million people around the world a chronic undernourished yet this is nothing compared to what may be to come. by two thousand and fifty two billion more people food production will need to increase by seventy percent meet demand. by then climate change could have increased food insecurity to disastrous levels it's a fact already being felt by farmers around the wilds but solutions are being developed to help them adjust to new conditions so they can feed a growing population as climate change intensifies. i'm tony cox in south africa to meet farm is taking space to boost agricultural yields and to find out about an extraordinary plant that could hold the secrets to create two crops can survive droughts and i'm guillory druggy in the mall where team of plant doctors are
helping farmers fight the pests threatening to wipe out their crimes. when you're traveling close to the give all this you have damn this is our major dam that the brought want to do cape town but also a large part of the war this is that for you guys you. know already you won't see this this is the old trees and used to be next to the never before the dam with both now they've been under water for close to thirty years now. and this is now the first on that they're really being exposed. this is really severe is the mid to be the worst drought in a one hundred years. normally we expect that the dam fill up in when they begin don't bring them down to about fifty percent by the end of silence
and then they can fill up again two hundred percent but it has there been for the last two years so he airplane yet in not filling up with a lot of the rains come because they're just not enough for a lot of rain so we won't ever go back to the good old days from the water that when there was ample water. the majority of south africa's farm is a small holder and their crops of rain fade so when weather patterns are disrupted it can have a devastating effect on their yields and livelihoods. thomas got that is one such fama living in the bloodline region he has a small herd of goats a few pigs and is hoping to grossly guavas this year. but when i visit his range fed reservoir is almost dry. enough when i am from the more she when you come in to. one of the. two thousand and sixteen.
with the indians admitting i am so good to see the good. old sweat give me a secret my foot on the ends of my body so my stalker who could see his eye when i said what would right. my need i'm too nice an africa been examined him so i mean it's a good. this man is if we had a cool woods fifty one. was optional it. was if he tried doesn't lie about john and i want to. change but this is the this is the road by a. good quest is riaz you're one of. the words are going to win in the one hour since the one nine hundred ninety s. south africa has lost over a third of its fans largely due to water scarcity as the droughts become more severe and the boreholes try a pharmacist like thomas are going to need a radical solution. professor to fire into the university of cape town is hoping to
provide that jilts research focuses on a kind of plant with some extraordinary properties and she's ideally situated because one type grows wild in the hills just behind the university campus this is it looks good doesn't it it does but it's not it's actually it's dried it's lost all it's water and it's cold it's it's front into a very protective kind of way how long can it survive like this. months two years depending on the species and the moment of rain the thing rehydrate with their two hours within two hours you know three years of two years out of one species we kept them dry for ten years. probably if they were. i'm trying to unlock the secrets of how these plants can actually lose all wet amount of water and not so once you understand these plants better and secrets what do you do with us i make crops do the same thing that's mine. jill takes me back to the lab where her team is busy
and locking the secret of these so-called reason rection plant i want to put this one on here and then start the re watering process so that you can see this magic of resurrection ok so we just want to the roots the respects. give the leaves a little bit of slack rein transmitter and rain and the thing about farmers in africa is that all the over culture is rain so those who can afford irrigation great but if there's no rain for the bulk of us there's no problem in the nice thing about this type of crop is that it will start off well it is lots of rain it will continue well if there's lots of rain but should there be a drop in the plant won't die when the next rain comes it will continue growing the farmer can at least get a harvest and you can get another chance of life as a group. talk to fans teams first objective is to understand what gives these plans these unique properties like we did here it was like we extracted some of
these proteins from one of the resurrection plans and reduce genes to the book tyria so now we're trying to produce proteins in a large scale so these proteins are part of the plant's arsenal to protect itself against the lack of water right that is the sort of protein that we are looking into water it has no structure whatsoever as the bronze drawing the water molecules are disappearing but this protein falls trips a whole lot more on the search retains its role to him by changing shape correct right very intelligent system. you know i can run away from my challenges because i have to face every street which is as eating an instinct eating fungus and then with the lunatic. and they they have these amazing ways of just recovering and responding to.
oh wow hair like it's resurrected. amazing to think that the plant that we saw earlier that looked dead basically now looks completely alive and i'm just picturing. a farmer's field where the maize is completely dead because there's been a drought season and in the rain finally comes again and the next day it will look like that the potential of that is staggering. the most promising crop for achieving resurrection is test a populist cereal throughout east africa. but jules team recently had a big breakthrough they were able to prove that the genes responsible for the regeneration process are already present in all plants this gives a lot of hope for a future drought tolerant crops mean the bad thing is to be able to leave this planet started to post and make a difference in africa
a continent that i grew up. with long dry seasons and unpredictable rains farms that can afford to irrigate their crops almost two thirds of south africa's total water requirements are used for irrigation but in times of drought severe restrictions are put in place forcing farmers to become smarter with their water usage the devitt family orchard just outside cape town produces around seventy million apples and pears each year and exports they produce around the world. all. right thank you for having us. to ensure their orchards and business survive the davits need to be more precise with their water usage and they're now able to call on a high tech solution. one of the new technologies we have. this. is
a precision agriculture tool that helps farmers grow more with less analyzes satellite images meteorological data i'm available local da to send to provide real time accurate information about crop health. a satellite image can. view crops in different light spectrum pixels and then be analyzed against models to identify stress before you can even see it with a visible i. can react more precisely and quickly any possible problems. so what does what does the information tell us about what's happening on the farm right now. growing a. weekend and out of ones so that the yellow patches mean that that's not as good growth. ok i think we should have a look ok so we can go see what's actually happening in. the beginning to. even before i want to start showing in my dad's generation this
was unthinkable. this is the one thing. that's fine it's the next irrigation is scheduled quite soon. so that should be fine also this part is ok so we've got to go looking and see where the problem is yes. a little further down we test the soil again you can see this is much more clay so it's more the holding capacity of the soil is weaker. so what will you do to make sure that this can catch up to some of the other options on the next round of mulching differently put some. more mulching allows for water to be held around the roots of the tree simply increasing irrigation would waste water as a train's off in the case oil knowing this helps pull manage the use of water more
effectively in his orchard ten years ago you would have been happy to fifty times what i am is now eighty two hundred pounds and it's just good fun practices and it's nice to carry just coming in to make a couple of. twisted so. for us. it's better to not pull it because then you get too much of that stem coming off with it so if you want to get a clean break you lift it up and over instead of pulling it down. it's incredible to think that the pears that we pick here today will be shipped all over the world to china to the middle east and that the farm is the workers who work here i'm making food that will be eaten all over the world it's important work that they're doing. is enabling farms to reduce their water usage
by around fifty percent it's successes have made the cultural department of the western cape to a fruit look for free to farmers in the region only those with the technical means to access from able to benefit from it however thomas is installing some basic irrigation on his farm this gives him some hope for the future litigation the brazilians are going to be i want a month. and can i ask for the equine life. so it. will probably you know on. the income good will be a one eyed is a couple of. projects by each year or ten. given to go by as you want to get by the get up with it would quite likely protocol you walk. by in july i took a bar says. she tugged on.
satellite data is being used in many ways to enhance food security. to focus dry suit in southeast asia with eighty five percent accuracy. to understand how best to grow food in south america by mapping cropland across the continent to help african herders identify grazing areas through maps and home about five times that by having heard mortality and to monitor the status of all nigeria's crops on a monthly basis. we know more than we ever knew and we have an understanding of our planet as a closed system that we didn't have to before we have a new generation of satellites up there that have a resolution of down to ten to ten meters today for example i can give you with seven days' accuracy a complete picture of the bennett with every single tree on that so all the
information you need is there but you really need to get it down to the farm most of the food that is being produced on this planet is actually produced by smallholder farmers farming families now these people learn from and on the basis of traditional knowledge. if the weather patterns are changing as they do because of climate change then you need a source of information to adapt what you're doing and in that mobile technology offers us until you see them to possibility there's virtually no space or you couldn't agree with the farmers and closing this gap between big daytime small farms that's one of the very promising but there's nothing that defines the interface between natural resources and human activity like agriculture does because there's no other sector that is employing more people than i would actually so if we get this sector right the potential is enormous not only to secure food production but really to secure the natural environment that keeps us in.
warmer climates and a greater movement of people and goods around the world are posing a new set of challenges for farmers pests and diseases are also becoming more globalized causing forty percent of all crops to be lost each year threatening the livelihood of small holders and also posing a great risk to global food supplies. here in the paul almost all fruit and vegetable plants are susceptible to attacks by insects and with two thirds of its population in farming new pests and diseases could spell disaster. what is it about nepal's climate that makes it particularly vulnerable to these pests and invasive species when we see that globally this so there is definitely an impact of the climate and exceptions. that not so much of what trade was happening
between the countries now the trade is happening so more perhaps coming so definitely more tests coming and the climate here is now getting more suitable to the past it catches the quite sudden and they are not able to. you see last year in two thousand and sixteen the tomato growth was almost effort by seven to one hundred percent in some pubs so it was a huge loss for the farming community. to help farmers lose less of what they grow a global program called plant wise have set up a network of regular clinics to rapidly diagnose pest problems for small holders i'm checking out this morning's mobile plan clinic which seems to be already pretty buzzing today isn't cancer town just outside of programming. almost nobody is going to get away with families of people would like to have you don't know if the money so many. people are getting. rid of it and think it's
everywhere. seems to in most of the. sparkle one succeeded so a lot of farmers are dealing with this problem. how exactly does a plant clinic work. if the people that need these are people way off for giving farms to the farmer by observation. the farmer and the. farmer ok so they bring in their samples they show you the infected props and you can give them a diagnosis right away just like a doctor when you go and you're not feeling well and you write your prescription you're doing the same thing here you're writing a prescription for the farmer. and the message from the staff remember this and that e-commerce and when you stand to lose more when he's ahead easier far in part an external. how much would you say climate change and warming temperatures have
affected outbreaks and pests in the paul are you seeing more and more cases. in. the. region there is a local smallholder who has discovered a larvae that has infested and damaged his tomato crop up to you. and i am i am here to make you believe that they will do both of what. you that one of the stimulus bill had written. to the senior officers just taking a quick look when you can see his crops are badly infested little. this is the lot of history. this is. the black leg martin oh.
this is the sign of. his entire tomato from misunderstanding just ten fifteen days it's destroyed that yes there's a very very infected plant. region there is added to the clinics database to track the two to absolute and waits for his prescription. to the absolute just started life as a larvae that eats the tomato fruit before transforming into her mouth and moving to a neighboring plant where the cycle starts again it is recently been reported in nepal and is spread rapidly devastating crops i want to find out more about this invasive species so i'm going to meet dr badger ceria a tutor absolutely specialist at the nepal agricultural research council.
what are you working on over here. south american from at least mine and that is go to africa in our scientific name this was from one nine hundred sixty that confront the south american one but in two thousand six it was the border from past time out of the south emitted at the from. then it given to that would hold him in the dark and come two thousand for it was deported in india after that because of the open border and we wanted and system between nepal and india at this best from the imported order from india but how many years do you think it's going to take until nepal is completely two to absolutely free or has really diminished the invasion. actually is very difficult to get rid of this best once it is introduced in the. can we completely eradicate we can take it any place but we have to make it so we can live at home with a good africa. with farming communities locked into
a globalised world threats to crops from new invasive species are slowly becoming the norm plant wise now operate in thirty four countries gathering data to form a knowledge bank track outbreaks and protect small holders i catch up with ridge india at his farm i want to see what can be done to rescue his devastated crop. wow these are tomatoes yes they're all completely destroyed yeah completely destroyed i. get money from these groups it helps to make. family to support your family and support. how much do you think you've lost with this infestation how much money. do you thousand. and forty percent i had also for some poor both my more well what are you still alive ok recently dig
the sport from this. ok so green and full of tomato. greens what a shame. shiva beryl a doctor from plant wise has come to show ridge and how to use a simple trap to manage his two to absolute infestation the trap emits a pheromone that attracts the adult male mark soapy water is added to the basin which the moth then falls into by reducing the number of males the population can be controlled without the use of pesticides. how many days until this entire area is treated until the outbreak has gone. one one. one how many months until the coming season just a two month tour in two months he could be fully back in business going healthy tomatoes again just from the simple device that's great how do you feel about that
. globalization is happening the world is developing and we can't slow that down. so you can see how an outbreak or a problem in peru could very well be the same issue for a farmer in a fall the very next year. and so plant wise is network of local plant doctors and clinics supported by an international pest and disease database enable smallholder farmers to be more prepared in the face of new threats from climate change in an increasingly globalized world. is going to be a tool to produce enough food for a growing population as the world's climate changes but the work has begun. where whether its extreme new varieties of crops are being developed and methods to grow
last year there are more than thirty metres in this community in one month the police say this area is a red zone one of several in some townships and children sometimes it caught in the crossfire when rival gangs fight so parents and grandparents have started what they call a walking bust to try to take the violence i lost my. go i also lost my but there are more than one hundred fifty volunteers working for several walking busses teachers say it is working class attendance has improved the volunteers also act as security guards hurrican have used destruction was indiscriminate good will there be an equal recovery i didn't want to be the mayor of two cities i have and have not fought lines discovers how the disparity between rich and poor is brought to the surface in times of crisis that someone's life who they are their identity their culture. lives houston off to
harvey at this time on al-jazeera. i was told by the pakistani army to the americans and we got held in guantanamo a number of detainees transferred to u.s. forces in afghanistan has continued to grow for years without trial they had to pay for that they were missed. or screamed would be beaten again a quest for a better life but ended in incarceration. of one ton of oh twenty two at this time on al jazeera. this is al-jazeera. thang.
