video and event. we have at the back of this practice. songs to sing along down lines. to be able to. have very kind of interactive exercises writing about them d.j. when you don't comes to ash junction and i'm on facebook in the am still. jammin frame may be deafening. hello and welcome to you could africa the pan-african european environment my visine am now coming to you from the beautiful show they got in lagos nigeria so
this program is a special edition featuring insects and the crucial role they play in our environment and ecosystems well he has a quick look at that and some of today's others topics. but the mix of biggest national park is a treasure trove for insect research shows we find out why that you. will be talking to and from all of just a sunday cassim nairobi to hear about the coming state but inside the world in africa we'll also be talking about for the way a young french woman has come up with a simple solution and we'll talk with the problem. in say they are everywhere they are an outstanding nine hundred thousand different kinds of living insects known to scientists that icons of about eighty percent of the world species and new ones are being discovered every day that's discovered although this guy.
thanks to their dedication searchers like the team guards are more than big. national park. just no prying is too small here in the garden grocer national park in mozambique ricardo gutierrez out hunting but he's not looking for lions or elephants he's looking to bag insects with this. door on this insect belongs to the beetle family caught up in the ground beetle family. so if you touch it it's a cretin assoc a liquid although you. riccardo works with entomologist piotr not scratchy in the e.r. wilson biodiversity laboratory. one objective of this research facility is to document the diversity of its insects finally got it from some insects yes. some
of them up there some beautiful some of them have been gone go so international scientists work with locals to find out about mozambique's rich biological heritage types of and ricardo has called thousands of insects for the park's team of experts to identify. usually a song like marks on the right is ok. to base contains information on all the animals and plants found in the park and that includes insect they play a key role in the true chain. with scientific research and. after nightfall is when insects come into their own feet. trap based on the principle that moonlight influences in behavior.
the leaving the artificial light is the moon the insects begin to spiral so that they remain parallel to the light source. it is insects who actually run the world they are some of the most important elements of almost any ecosystem. and it's a restaurant ecosystem i think provide and of services without which we would be able to function so things like you know all the smart without down all the trees and vines without around this would be able to produce fruit to people who live near the national park benefit from the protected area in a number of ways. locals used to live mainly from poaching now they have regular jobs. the research is all working tirelessly. with the help of ned state also want to find out more about the feeding passions of bats . us they make most progress it nice
and expert on bats is using an instrument to identify sounds that human ears can't normally hear. the same day back. this is why. that was a warning call. the recordings are highly informative this is a very big place to study this because we have a high diversity about species diversity of insects the seeds and we're surrounded by areas that suffer from malaria and also where crops so it's an ideal place to study the interaction between bats and insect species that plague humans. it's believed that scientists are only aware of about ten percent of existing insect
species in coming years the research is a darn gosa park will likely discover thousands. thanks in part to a cut of and his net. now we'll be hearing more about the role in play in africa and how they are beneficial to human nature as a whole dr sunday cassy is an entomologist and pest management specialist at the international center of insect physiology ecology he has done a lot of fascinating research into bio repellent bugs as a reliable food source and how insects excellent by indicators of climate change is what africa caught up with in nairobi.
this is. also far from. what we do exploit these diseases. and music. to reline. what we have been doing over b.s. is the past commercialized various products on the basis of this understanding we able to isolate or carry out bio perspective or exploration find dead insects or isolate these pathogens all these bacteria fungus from the insects culture. and mass produce it and once we have done that we prized knowledge to the private sector that provide proof these by a pesticide as on time and to do use of synthetic that is harmful to the environment. the
utilization of insead for food and feed has really taken africa by storm because initially the knowledge was little known but. we went into these programs and began to let people know all of the value of insect terms of consumption and for food we discovered that there are over five hundred different kinds of incidents that are eating across africa so we began to walk with the police to make us to ensure that stand that's. an asterisk speak now have the first stand for freedom and for food in kenya and in uganda so we need to see more of this across africa and big kenyan example has opened the door for several countries to begin to embrace the need to have stand that story short that these products are available all across the place . change is
so important for insects because it affects the development that affects the outer production and it affects the survival as the temperature warms they develop. when they develop. their minds very quick. and stitch when you don't even expect them to and we have seen this happen in the order. so it isn't distribution because temperature is warming that is the tendency for the inserts to begin to move. from to warm area. so it changes in distribution of patterns. happens climate science has all kinds of impact on insects and really good indicators one christmas and i listen to pollinating fruits and flowers and vegetables insects give us and many other things
we would probably not want to do without honey bees wax so just a few examples as you have. many credit for your prosthetic insect. plants or animals so they can play on important role in pest control gardeners love lady bugs because they devour a fed's. cats and his staff breed the colorful beetles and send their eggs to mainly private customers his company has been in the business for over twenty years not all their beneficial bugs are suitable for use outdoors. if you capture grown lady bugs and want to use them somewhere there's always the possibility that they will fly away so if you deploy ladybugs only in enclosed spaces. minute predatory mites on the other hand tend to stay put here they've made
themselves comfortably at home on some bean plants the staff then harvest them along with the leaves they're attached to the predatory mites have already decimated an entire colony of spider mites here and bred prolifically in the process just a few leaves are enough to provide a customer with more than a thousand of the useful predators. became natural pest control works particularly well if you use beneficial insects at the first signs of infestation you have to look at it mathematically if you have one hundred million pests you need a hundred thousand beneficial insects to fight them that's an enormous number if you only have a thousand pests you only need twenty beneficial insects so you have to identify the infestation at an early stage and deploy beneficial insects straight away through. the tiny pedrosa toward wasp and foremost is also bred by cats biotech here on these tobacco plants it's helping to tackle
a species commonly known as greenhouse whitefly a big threat to commercial crops worldwide the little black insects of specialized and white flies next door where they had a plentiful supply the wasps have multiplied they lay eggs and the living larva of greenhouse whitefly which eventually kills them. business is booming the company sends insects to fight plant pests to customers across europe transport has to be speedy since both insects and their eggs can perish along the way katz has also visited greenhouses in ethiopia where plant breeders work with beneficial bugs but he says in conventional outdoor farming in africa it's not really advisable. that hamann or paul in europe we have the advantage of having cold winters in this period the past population is refused to. zero but in tropical or subtropical
regions that's obviously not the case this pest populations there persist throughout the year it's very difficult to work with beneficial insects when pest infestation levels are high five and in my opinion that can only work in isolated cases and warm i ninety five cleaning so preferably in controlled environments like greenhouses because beneficial insects have their limits the company also works together with the chemicals and a stray cats is preparing predatory my dogs for a manufacturer of conventional pesticides the industry is working to develop substances that won't kill the little helpers peter katz says that without artificial pesticides food security isn't achievable instead he wants to see chemical agents that have a lower impact on predators they can kill pasts like these green lace wing larvae which hoover up in a big way they're a real boon for any garden in ghana's low income. sun isn't situation
it's pretty. shocking it's five percent of gun and lack access to adequate toilet facilities that means they often have to relieve themselves in public places and that is having a negative consequence both on the health of the population and the environmentalists one company called wash kings is offering a solution eco friendly bio digester toilet yeah i think check this out. after a week of work the bio digest is ready. around a hundred of these. have been built in. their inventor. supervising the construction of a community compound. isn't that the base of
the digest. and they will come and fix their videos might say yes. on that basis on the toilet needs little water that's important so much as water is scarce on down and on and this is how the guy that i just to work i said what's your hunch. and which one. now you want shon pleats i'm going inside. the toilets require a little more than health a little flushing water. liquids and solids a separate edge and then ximenes added to the solid waste to help it degrades more quickly deal don't i would have studied conversation and resource management he made it his goal to provide widespread access to clean toilets after sometimes it was me a challenge i sometimes got to go to the beach where you boys lose yourself to a lot of risk the risk of somebody may be watching the one watching.
you and also being asked to beaten by snakes where us older eighty percent of the canadians have access to clean water fewer than twenty percent have access to clean toilets and that's according to the world health organization generally you have to pay to use public toilets and they're frequently not very hygenic often trucks dump the waste collected into the sea those in another health risk they'll tennessee for most canadians death occasion in the open also hardly in the tracts of option the bad guy just was mainly invented for low income households by the toilets and cheap the range in cost from around four hundred to nine hundred us dollars michael of law and his fellow residents were able to finance it to find out yeah yeah if you keep a young nephew in the house or choices to be out there i don't believe. which used
to be here again. you can hardly see why you would use then you use your powers and there are more benefits local people working here and a steady income as well as learning transferable skills more than twenty people have already been trained now i have been working which was helping yellow look after my wife my children and i'll be able to pay my total school fees pay my bills pay everything about the house i'll be able to do everything i do don't set up his company two years ago last year against a price won an award for integrating social and environmental benefits into its business model. now let's talk about food safety today many processed foods come with a sell by date and you open the law for big supermarkets to be pulled out on
shelves once they've expired yes that's what sell by date means i mean by that is that in time the problem is unless we're talking about a wrong meets all the perishables the food come still be consumed without any risk restaurants have a similar problem what to do with leftovers that are still good enough to eat so when it's time to close the kitchen for the day a young woman named fons is doing something about it she's doing her bit to cons are rocks the throwaway culture and it is a concept that's cutting off. solidarity for a chance. eighty eight million tons of food and wasted in europe every year. that amounts to one hundred seventy three kilos. and made a truly amazing restaurant in paris. she wanted an alternative to turning unsold
food away. in jeans when she seventeen she sets up a solidarity fridge in front of her restaurant. inspired by a concept from berlin the idea is simple anyone can take food from the fridge or add to it. through some vegetables and cool kinds of produce how well. the fridge is are financed with the help of crowd funding campaigns. they can be set up in just five minutes. now the fridge is a spreading across from. the message to the students at the. to be more aware of the any and thank you for mission. like that. if you're also
doing you want to tell us about it. visit our website or send us a tweet. as to doing your bit. or stories. for centuries lots of people here in africa lived on the plans an animal's that they found all hunted in the forest they only took what they needed to survive fos war to present day many of those same areas are now national parks established primarily to protect the animals especially didn't they did ones that are found within them from falling prey to supporters of course of national park in cameroon is a good example rangers but song corrupt national park in south west and coming on practically around the clock it's their job to protect the surviving animals from porches people who have been living in this area for centuries hunting for food has
a long tradition p.-a. pretty good. we feel very very happy and we don't have anything added. but now many animals in coming out of thirty and with extinction. rain just and conservationists use kind of the traps to record the collisions in national park. in particular primates. and little monkeys are endangered they're hunted for food or sold on illegally. this is often the only chance that people living in and around the national park have to and money. but in the village of things are different the head of the national park has come to visit his give it
a ceremonial welcome people here used to be involved in the illegal bush meat trade but now the villagers cooperate with the park rangers the inhabitants benefit from sticking to conservation groups solar power for instance was introduced to the village in return. they couldn't look at people because. or. so for the first time. at every stage. of the fact that we have different ending in living inside. like former hunter john paul for example hunting has become increasingly strenuous for the fifty nine year old. nowadays he cultivates bananas cocoa beans and mangoes the conservationists would like to persuade more hunters to follow his example. his family today enjoys a higher standard of living than they did in the past. more than
a hundred thousand francs i think i could plant even more land because it's very easy to find the hosting is very easy just. lay them out to dry in the sun and sell them it's not as hard as hunting use to have a lot of problems with that. in the community a hole in the head of the village announces a ban on hunting all family heads have agreed to the missions and the sanctions are touched. ten men are handing over their guns to the conservationists the villagers getting ten motorcycles in exchange the first men are already receiving driving lessons they used to be hunters. now they'll be able to handle living as krieger's or taxi drivers. this truck through the rain forest is quite a meal a breed under construction tool on food it takes six hours to reach the next
village. and sometimes when the river rises it's impossible. their axes will enable people to sell their goods at the market but john is hoping the route through the forest will remain just a dodge truck he feels that a proper road could attract illegal logging. of forest is a friend of mine. if this forest disappears i might even die myself i also can supply. the conservation program has shown inhabitants that environmental protection can help them thrive to. well we've come to the end of this edition of we hope you enjoyed it as much as we enjoyed see you . next week more interesting stories. thank you for watching you can get in touch with us and our social media platforms
