video and event. we have to thank you for the skype the. songs to sing along to download to see this to come. to you from doing. things kind of interactive exercises writing abounding d.w. don't come sasha johnson and i'm on facebook in the i'm still. jamming frame may be deafening. hello and welcome to you could africa the pan african european environment magazine am now inside me coming to you from the beautiful showed it's got in lagos nigeria
8:31 am
so this program has a special edition featuring insects and the crucial role they play in environment and ecosystems but he has a quick look back on some of today's other topics. but the mix of biggest national park is a treasure trove for insect research as we find out why that believe. it will be talking to and from all of just a sonic cassim nairobi to hear about the calling state but insect world in africa will also be talking about for the way a young french woman has come up with a simple solution we'll talk with the farmer. 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 being discovered every day that discovered all those discoveries.
8:32 am
thanks to the dedication of the searchers like the team guards are some big national park. just no prying is too small here in the garden gosa national park in mozambique ricardo gutierrez out hunting. but he's not looking for lions or elephants he's looking to bag insects. with the. door on this insect belongs to the beetle family caught up in the ground beetle family. if you touch it. it's a cretin liquid although you. ricardo works with entomologist. in the wilson biodiversity laboratory. one objective of this research facility is to document the diversity of its insect find regardless if something is your.
8:33 am
son or do not know some beautiful some of them have been gone ghosts or international scientists work with locals to find out about mozambique's rich biological heritage types of ricardo has called thousands of insects for the parks team of experts to identify. and promote them and usually has some like markings on the way. and. the database contains information on all the animals and plants found in the park and that includes insect they play a key role in the future. with scientific research and morning. after nightfall is when insects come into their own feet feel great he has set up a light trap based on the principle that moonlight influences in behavior.
8:34 am
believing 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 are they are some of the most important elements of almost any ecosystem almost any to restaurant ecosystem of our day provide and number of services without which we would be able to function so things like polarization you know all the smarts without down all the trees and vines without those around us with a view of these fruits. the 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 researchers are working tirelessly with the help of nets they also want to find out more about the feeding patterns of bats . us they make most progress at night.
8:35 am
and exposure on bats is using an instrument to identify sounds that human ears can't normally hear. right. and. this is why. there was a warning call. the recordings are highly informative this is the perfect place to study this because we have a high diversity of that species diversity of insect species and we're surrounded by areas that suffer from malaria and also where people cross 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 the bout ten percent of existing
8:36 am
insect species in coming years the research is a darn gosa park will likely discover thousands. thanks in part to recut 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 source on the how insects excellent by in the cases of climate change what i think i caught up with in nairobi.
8:37 am
one of the critics wrote. about five percent of. various kinds of. very very point. for instance they cannot make value of point emissions by insects our animals in general. could be as high as five hundred and seventy seven billion dollars globally this is huge.
8:38 am
fight by the insect diseases because insects out so attack by disease could be fungus bacteria could be protozoans they all suffer from this kind of this is what we do is to exploit these diseases of insects and music to control the insects to see the real line of pesticides and what we have been built over the years is the best commission lies various product on the basis of these understanding we are able to isolate or carry out bio perspective or exploration to find dead insects and isolate these packages all this bacteria fungus from the use its culture it and mass produce it and once we have done that we transferred this knowledge to the private sector that provide that provision this by pesticide as on tiny to the use of synthetic present that is harmful to the environment.
8:39 am
they utilize ition of insead for food and feed has really taken africa by storm because initially the knowledge was little known but minutely we went into this program and began to let people know of the value of consent in terms of consumption and for food we discovered that there are over five hundred different kinds of insects that are eaten across africa so began to walk with the policy makers to ensure that stand that's are developed and asked respect now have the first standard for feed 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 african countries to begin to embrace the need to have that story short but these products all across the place.
8:40 am
which are important for insects because it affects the development affects reproduction and that affects their survival as the temperature warms they develop . and when they develop there is a tendency in said when their minds very quick. at an early stage when you don't even expect been. and we're seeing this happen the order. changes in distribution because the temperature is warming there is the tendency for the insects to begin to move. from too warm area to too. so it changes in distribution of patterns or contraction happens climate science has all kinds of impacts on insects and insects are really good indicators one christmas. pollinating fruits and flowers and vegetables insects give us
8:41 am
many other things we would probably not want to do with honey bees once said just a few examples as it has. cassie there are many predatory insects that prey on plants or animals so they can very important grow in pest control gardeners love lady bugs because they devour a fence. 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. of oxen if you capture grown ladybugs and want to use them somewhere there's always the possibility that they will fly away so if you deploy ladybugs then only in enclosed spaces. minute predatory mites on the other hand tend to stay put here
8:42 am
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 it's the tiny pyrrhus a toyed wasp and foremost is also bred by cats biotech here on these tobacco plants
8:43 am
it's helping to tackle a species commonly known as greenhouse whitefly a big threat to commercial crops worldwide the little black insects have specialized in white flies next door where they had a plentiful supply the wasps have multiplied they lay eggs in 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. to home in all parts in europe we have the advantage of having cold winters in this period the past population is reduced to zero but in tropical or subtropical
8:44 am
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 war i ninety five killing so preferably in controlled environments like greenhouses because beneficial insects have their limits the company also works together with the chemicals industry katz's 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 can't 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 when larvae which hoover up any feds in a big way they're a real boon for any garden in ghana's low income. times is
8:45 am
a situation it's pretty. shocking it's five percent of gun and 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. one company called wash is offering a solution eco friendly bio digester toilet yes thing to check this out. after a week of work the bio digester is ready. around a hundred of these eco friendly toilets have already been built in and around across. their inventor. is supervising the construction of the toilets for a community compound of across. this is the best of the digest.
8:46 am
and they will come and fix the videos might say yes. on that basis on the toilet needs little water that's important as much as water is down and on and this is how the i and i just a worthless unless you hunt. and with what i buy you watch the hind meat in the book inside. the toilets require little more than healthy little flushing water. liquids and solids a separated and then zine is 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 i sometimes it was maybe a challenge i sometimes got to go to the beach playboys because you're stuck to a lot of risk the risk of somebody may be watching the impact watching.
8:47 am
you and also being asked to beat him by snakes where us over 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 bosun another health risk they'll tennessee foremost in the ends death occasion in the open also hardly in the tracts of option the bad guy just was mainly invented for low income households while the toilets are not cheap they range in cost from around four hundred to nine hundred us dollars michael of law and his fellow residents were able to fine and six hundred fifty thousand dollars yeah yeah if he'd been up there fifty of us are choices to be out there i do believe. which is just to be sure i hate. just to
8:48 am
argue see what i'm doing which is going to 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 the help in yellow to 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 i 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 up the lawful bit supermarkets to leave pulled out on shelves
8:49 am
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 war 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 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 a bit it's a concert act this threw away a 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 anything that amounts to one hundred seventy three kilos a personal. journey i made a truly amazing restaurant in paris. she wanted an alternative to stirring unsold
8:50 am
food away. in jeans when she seventeen she set up a solidarity for eggs in front of her restaurant. inspired by a concept from berlin the idea is simple anyone can take food from the fridge pointed to a. tree some vegetables and cool kinds of produce along. the fridge is a financed with the help of crowdfunding campaigns. they can be set up in just five minutes. now the fridge is a spreading across from. the message to the students of the. to be more aware of any and thank you some mission. like that. if you're also
8:51 am
doing your bit 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 item was found all hunted in the forest they only took what they needed to sub on phosphor to present day and many of those same areas are now national parks established primarily to protect the animals especially then they did ones that are found within them from falling prey to supporters because of national park in cameroon is a good example rangers but song corrupt national park in south western canada on practically around the clock is their job to protect the surviving animals from porches people who have been living in this area for centuries hunting for food has
8:52 am
a long tradition in the new property. it would be very very happy. to 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 copulations national park. in particular primates. and little monkeys are endangered there hunted for food or sold on illegally. this is often the only chance that people living in and around the national park have to unmuddy. but in the village of things are different the head of the national park has come to visit his give it
8:53 am
a ceremonial welcome people here used to be involved in the illegal bush 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. so for the first time. at every stage. of the fact that we have. any in living. 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 one
8:54 am
hundred thousand francs i think i could plant even more land because it's very easy to find the homeless things very easy you just. lay them out to dry in the sun in some of them it's not as hard as hunting used 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 village is getting ten motorcycles in exchange the first men are already receiving driving lessons they used to be hunters. now they will be able to under leaving as school girls or taxi drivers. this truck through the rain forest is quite a meal a bridge under construction two on foot it takes six hours to reach the next
8:55 am
village. and sometimes when the river rises it's impossible. better access will enable people to sell their goods at the market but john is hoping the route through the forest will remain just a dark truck he feels that a proper road could attract illegal logging. a forest is a friend of mine. if this forest disappears i might even die myself also can subpoena. the conservation program has shown inhabitants that environmental protection can help them thrive tool well of come to the end of this edition of we hope you enjoyed it as much as we enjoyed see you. next week for more interesting stories. thank you for watching you can get into hospitals and our social media platforms i guess is what
