we always heard about the so-called arab spring in certain other countries so this is our version our saudi version of arabs being our piece for. out of spring so what's happening now is not the evolution frankly speaking i would use it that it's happening right now a very peaceful one in saudi arabia russia has rejected the findings of a un inquiry into a chemical attack in syria in april un investigators concluded the syrian government was responsible for the use of sarin gas in the rebel held town of concept khun more than eighty people died many of them children the british aid minister pretty patel has reportedly canceled her trip to africa and is returning to london amid accusations that she discussed secret deals with israel the international development secretary has apologized for an unauthorized meeting with israel's pm prime minister rather benjamin netanyahu in august while on a family holiday at least four people have been killed in an explosion at
a turkish paint factory it happened in the northwestern bus a province a gas build up in a generator is being blamed sami said and is here with the news out for you in a little over twenty five minutes on al-jazeera right after earthrise next. germany is hosting this year's climate talks from the united states out of the paris agreement what enough of the global effort to tackle climate change in-depth analysis on live reports from the climate conference in bomb and from the frontlines of global warming climate s.o.s. one or zero.
some people don't have to worry about whether the next meal comes from. but these food supplies weren't always be so reliable. eight hundred million people around the world economy undernourished yet this is nothing compared to what may be to come. by two thousand and fifty will be 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 world 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 in south africa to meet farm is taking to space to boost agricultural yields and to find out about an extreme reply and that could hold the secrets to create two crops can survive droughts and i'm guillory druggie in the mall where team of plant doctors are
helping farmers fight the pests threatening to wipe out their crimes. been examining close to the give others who have them this is the hour major dam that the brought want to do cape town but also a large part of the war this is good for you guys you. know already you won't see this this is the old treason 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 to 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 where can you get 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 it was ample water. the majority of south africa's farm is a small holder and their crops a rain feed 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. from what i mean for your company. but if one of the two hundred. sixty.
with got away and incidentally i am so good to see the good work up a. big old sweat give me a secret my foot on the ends of my body so my stalker who could see his eye when i could not would right. my need i'm too nice an africa been examined him so i mean so do. his money is safe we had a cool woods fifty one. was optional it. was as he tried doesn't lie about john and i want to. change what he says this is. why it is a. good place to see us is riaz you are 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. to watch. as the droughts become more severe and the boreholes dry up varmus like thomas a 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 its 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 always within two hours to about three years of two years how about one species we kept them dry for ten years. i'm trying to unlock the secrets of how these plants can actually lose all wet amount of water and not die so once you understand these plants better and unlock the 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 plan i want to put this one on here and then start the re watering process so that you can see the magic of resurrection ok so we just want to the roots the risperdal. give the leaves a little bit of slack rain transmitter and rain and the thing about farmers in africa is that all in all the only culture is rain baby so those who can afford irrigation great but if there's no rain for the bulk of us there's no crop in the nice thing about this type of crop is that it will start off well if there's 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 lot of history and you can get another chance of life as a group. talk to fans teams first objective is to understand what gives these plants these unique properties like we did here it was like we extracted some of
these proteins from one of the resurrection plants and it runs reduce genes to the book tyria so now you'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 correct right that is the sort of protein that we're looking into water it has no structure whatsoever as the bronze straw in the water molecules are disappearing but this protein unfolds trips a whole lot more on. certain retains its role to him by changing shape correct right very intelligent system. you know i can run away from my challenges because they have to face give me strength which is as eating an instinct eating and funding and then when the cylinder head you. and they they have these amazing ways of just recovering and responding.
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. the most promising crop for achieving resurrection is test a populist serial 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 for me the thing is to be able to leave this planet started a process 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. orchards. is
a precision agriculture tool that helps farmers grow more with less analyzes satellite images meteorological data and available local da to send to provide real time accurate information about crop health. a satellite image to. view crops in different light spectrum the pixels and then be analyzed against models to identify so 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 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 then. you can get it. even before i want to start showing in my dad's generation this
was unthinkable. this is the one. 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 no 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 well and is now eighty two hundred pounds and it's just good fun practices and this new technology is coming in to make us capable of. forming. an actual. 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 to visit years ago when i went to a month. before the little equine life there. so. you know on equal. 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. go by in july i took a bar says. she turned on.
satellite data is being used in many ways to enhance food security. to focused rice fields 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 above finds that by having hard 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 he were doing and in that mobile technology offers us until you see them to possibility there's virtually no space where you couldn't agree with the farmers and closing this gap between big daytime small farms that's one of the very promising the world there's nothing that defines the interface between natural resources and human activity like agriculture does the plays 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 where we see that globally this so there is really an impact of the climate and exceptions. that not so much of
a trade was happening between the countries now the trade is happening so more perhaps coming so definitely more best coming and the climate here is now getting more suitable to the past it catches the quite sudden and they are not able to be that you see last year in two thousand and sixteen the tomato growth was almost effort by seven to one hundred percent in some cases 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 clinic which seems to be already pretty buzzing today isn't cancer town just outside of programming. you know almost nobody is going to get away while the families of people would like to have you don't know if only so many. people are getting. rid of it and think
it's everywhere. in most of the. best to both of us but go on in six years or so a lot of farmers are dealing with this problem. how exactly does a plant clinic work. people that need people way off giving farms to the five hundred by observation. servicing the sample. the partner and the. farm worker ok so they bring in their samples they show you the infected hops 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. in the mesocyclone just as it. is and that e-commerce and will be distinctly smaller and he's ahead easier far in context and also. how much would you say climate change and warming temperatures have affected
outbreaks of pests in the paul are you seeing more and more cases. that's. bridgend a is a local smallholder who has discovered a larvae that has infested and damaged his tomato crop you. know you know i am i have to make you believe that. the lord will not use the middle of this. to the senior officers just taking a quick look when you can see his crops are badly infested. with a lot of the story. this is. in
the black on black mountain oh. here. this is the sound of. his entire tomato from it is damaged just ten fifteen days it's destroyed that yes there's a very very infected plant. region there is added to the clinic's 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 america from a leaf miner that it's go to africa in our scientific name this was this from one nine hundred sixty that confront the south american one but didn't six it was deported from perth time out of the south america. then it given to that would hold indian in iraq and tom 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 in nepal 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 get any peace but we have to manage it so we can live at home with the 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 this 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. but it wasn't forty percent i had also dig for some poor those my more well what are you still alive ok
recently dig the sport from this. ok so green and full of to me yes. 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 ma 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 is gone. how many months until the coming season. so in two months you can be fully back in business growing 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 nepal 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. it's going to be a tool order 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
them. where skills are being honed knowledge is being shed. food insecurity will become an increasingly pressing issue. but people are finding inventive ways of coping with new conditions. ingenious developments in the battle against illegal deforestation these are basically old cell phones that it was sent to us with love and it was in the forest and you can forget anything looked more like chainsaws or gunshots and in australia indigenous practices are being used to plant plywood pine if a metaphor like that will make about fire right about the time that we try get fair and just start yeah innovation and tradition. at this time on. business update brought to you by they always going places together.
