tv Eco-at- Africa - The Environment Magazine Deutsche Welle June 23, 2018 4:30pm-5:01pm CEST
in the course of. the lives of school starts july eighth g.w. . born. it's crunch time for germany how big a hurdle will sweep through to the. world cup two thousand and eighteen today on t.w. news. hello and welcome to you could africa the pan african european environment by the scene i 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 but he has a quick look at that and 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 some of just sunday cassim nairobi to hear about the common state off the insect world in africa we'll also be talking about for the way a young french woman has come up with a simple solution that will talk with the problem of. insects they are everywhere they are an outstanding nine hundred thousand different kinds of living insects known to scientists that accounts of about eighty percent of the world's species and new ones are being discovered every day that discover those discoveries are. thanks to their dedication searchers like the team guards are more
than big. national park. just no prey is too small here in the 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 . dormant this insect belongs to the beetle family. the ground beetle family. if you touch it and it's a cretin as cynical liquid although you. ricardo works with entomologist. in the e.r. wilson biodiversity laboratory. one objective of this research facility is to document the diversity of its insects find ricardo and salt something you say yes. some of them are doing some of those some of them have been gone go say
international scientists work with locals to find out about mozambique's rich biological heritage types of ricardo's called thousands of insects for the park's team of experts to identify a bright spot on the promontory usually has some light markings on the way to make . the dot a base contains information on all the animals and plants found in the park and that includes insect they play a key role in the future. ricardo says it's with scientific research and more training because. after nightfall is when insects come into their own feet feel like they're not scratchy has set up a light trap based on the principle that moonlight influences insect behavior thought the. even 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 around the world are they are some of the most important elements of almost any ecosystem almost any terrestrial ecosystem are they provide and number of services without which we will be able to function so things like pollination you know all the smarts without down all the trees and ferns without around this will be able to produce fruit. 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 passions of bats . yes they make most progress at night.
an expert on bats is using an instrument to identify sounds that human ears can't normally hear. and she's angry back and. this is. that there was a warning call. the recordings are highly informative this is the perfect place to study this because we have a high diversity in back species diversity of insect species 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 those scientists are only aware of the 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 cutter 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 and 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 i think i caught up with in nairobi.
by this business because. this is. all so far from. what we do exploit these diseases. and music to. line. what we have been doing over b.s. is the past commercialized various products and the business of these understanding we able to isolate or carry out bio perspective or exploration to 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 transferred his knowledge to the private sector that provide proof. by a pesticide as on time it to do use of synthetic present that is harmful to the environment. the
utilization of instead 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 eaten across africa so we began to walk with the police to make us to ensure that stand that's. a nasty 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 time 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 quicker. when they develop there's a tendency when their minds very quick and the crop at an early stage where you don't even expect them to and we're seeing this happen in the order aspect changes in distribution because the temperature is warming there is the tendency for the inserts to begin to move. from two warm area to two. so it changes in distribution of patterns. happens climate science has all kinds of impact on insects and really good indicators from one christmas and i listen to pollinating fruits and flowers and vegetables insects give us many other things we
would probably not want to do without honey. so these are just a few examples as it has. many critics prosthetic insects that prey on plants or animals so they can play on important role in pest control gardeners love lady bugs because they devour aphids. 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 then 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 it's 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 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 opar name 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 regions that's obviously not the case the past 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 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 when larvae which hoover up a fence and a big way there are a real boon for any garden in ghana's low income. times 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. one company called washington 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 the crowd. there inventor. is supervising the construction of the toilets for a community compound of across. 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 to send us your hunch. and with. that he was shot high and needs to feel good inside. the toilets require little more than healthy little flushing water. liquids and solids are 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 sometimes got to go to the beach where you boys push yourself to a lot of risk the risk of somebody may be watching the impact watching.
you and also being also beaten by snakes whereas 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 those in another health risk they'll tennessee for most indians 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 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 if you're going on the. yacht you think he'd be up to fifty one hundred sixty or sixty get out there and
get to meet. which is it to be here again. just to argue see what i'm doing which is going to use your powers and there are move on if it's 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 children's school fees pay my bills pay everything about the house 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 up the lawful bit supermarkets to leave food 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 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 bit to consular access the throw away of culture i mean is a concept that's cutting off. solidarity for against. you. eighty eight million tons of food and wasted in europe every year. that amounts to one hundred seventy three kilos the person. doing an maybe truly amazing restaurant in paris. she wanted an alternative to
turning unsold food away. in jeans when she seventeen she set up a solidarity for inch 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 whole kinds of tech produce a welcome in. the fridge is a financed with the help of crowdfunding campaigns. they can be set up in just five minutes. now the fridge is spreading across from. the message to the students and the money. to be more aware of the any. the thank you so much and. like that. if you are also doing your bit tell us about it. visit our website or send us
a tweet. as to doing your bit. more stories. for centuries lots of people here in africa lived on the plants and animals they found in the forest they only took what they needed to. fast forward to present day many of those same areas are now national parks established primarily to protect the animals especially the endangered ones that are found within them from falling prey to supporters because of national park in cameroon is a good example rangers but up national park in south western canada on practically around the clock is their job to protect the surviving animals from porches. have been living in this area for centuries hunting for food has
a long tradition here. pretty good. when we bring. it we feel very very happy and we don't have anything added be happy. about. it. but now many animals in coming out of thirty and with extinction. rain just and conservationists produce kind of the trops record of the bungling populations in corrupt national park. in particular primates. and little monkeys are endangered they're hunted for food or so don't illegally. this is often the only chance that people living in and around the national park have to. but in the village of that 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 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 this time making the local people because the center or or the resort affords so for the first time we were consulted at every stage is. who became convinced of the fact that we could have differing with any in living inside the national park like former hunter john a poor for example hunting had 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. they have a sting is very easy just to break the cocoa beans lay them out to dry in the sun and sell them it's not as hard as hunting i used to have a lot of problems with that. in the community whole the head of the village announces a ban on hunting all family heads have agreed to the missions and the sanctions attached. ten men are handing over their guns to the conservationists the villagers getting ten motorcycles in exchange. the first men out already sitting driving lessons what they used to be hunters. now they'll be able to under leaving as school girls or taxi drivers. this truck through the rain forest is quite a meal. on the construction tool on foot it takes six months to reach the
next village. and sometimes when the rebbe rises it's impossible. that access will enable people to sell their groups at the market but john is hoping the route through the forest with him in just a dock truck he feels that a proper road could attract illegal locus very good a forest is a friend of mine. if this forest disappears i might even die myself i also can subpoena. the conservation program has shown in hubby times that environmental protection can help them thrive tool well we've come to the end of this edition of eco africa we hope you enjoyed it as much as we enjoyed bringing it to you so we come your way again same time next week for more interesting and fascinating stories from across africa and europe thank you for watching you can get interrupted hours on our social media platforms i guess is
