a new episode of africa and i'm not alone joining me with my colleague. from nigeria. and hello everybody and warm welcome to the show. nigeria this week you'll learn why a german company is growing vegetables indoors but that's all we have on the show here the other things we have lined up for you. was it was on the. side of a partnership with the national park. will explain why sharks in both need better protection to survive. and we find out how one man in cameroon is making money. while at the same time helping. the african wild dog is viewed as one of the most endangered species in africa once covering almost the end continent in numbers half a million strong they are only a few pockets of them left in song. africa but that kind of war performs an
essential role in maintaining the biodiversity on the continent and they are integral to the regulation of phrase machines and the continued to tell the ecosystem as the largest is now come painting for the wild dog survival in south africa's kruger national park. it's not the baboons that are and so on marco has come to see all the larger animals that are always the big draw for the tourists there's a lot is this fighting for the survival of the african wild dog he sets of early in the morning in south africa's kruger national park the dogs are hard to find even for marco originally from belgium he's worked here for many years the lions are the number one for florida here on the lions and hyenas other wild dogs number one predators. one of the dogs is carrying
a transmitter so markel is hoping to track him down the sun is busy it's quite high already and it's going to get hot it's one of these summer days so whenever he gets up there were dogs are not on the move anymore so we must try to find them as they busy moving but despite trying for three hours marco can't pick up a signal he's starting to feel concerned. he shows us the enclosure where he held a number of dogs before releasing them into the wild. all that remains is the carcasses they left behind. programs like this one are designed to stop the dogs from becoming extinct. the biggest challenge was getting the animals used to each other as they were brought from different parts of the country while they were sedated we rubbed them on to each other. like that when they walk a brace rollie the good smell there their scent on the other dogs and then they
believe that they were part of the same park they are only one hundred thirty african wild dogs left in the park over the past twenty years the population has shrunk to one third of its previous size market has yet to ascertain why it can be disease many carried by domestic dogs to chose rabies and kind ninety stumper it can be the fact that there is too many competition with other people's phones and but he die not it can be the fact that there is not enough praise and it can be or saw some sneering so in france from the people who are outside the park onto the dogs in congo two days later it's another early morning start there's still no sign of the african wild dogs. and one more call has been scanning the bush each day and then suddenly i'm a hopeful sign. i've cut the cord to strong signal them about five hundred
meter i want to make it on the monitor approach he drives towards the signal and then keeps his ice peeled. the sense of anticipation is palpable yeah he's on. the rest of the pack appears colt an antelope wild dogs hunt as a pack they don't kill their prey immediately they eat it alive ripping apart stuff less with their teeth yes and they're looking good and it's nice to see that they're actually feeding so they've killed an impala man and that's an information that is very important to recall because we want to know what are their what is their protection. amazingly the hyena is lurking right nearby with an eye on the antelope meat but the pack is not peter treats on the contrary to get strong enough to keep the hyena in check. they drive it into
a ditch only once to dogs have eaten their feel and move on. to come out again for once it's the african wild dogs that have won in the battle for survival. announcer europe and from dry land to the mediterranean sea here are an increasing number of shark species on the threat of extinction. but charles knows more about that. yes. that drop in population numbers seem surprising given that you know. the regulations on shipping but scientists believe that many of them not adhering to the rules they are illegally offloading or leaking a block of oil into the sea one biologist in bosnia has been a have begun examining some of the ways abstracts found dead in the region with a view of finding out what is causing this population decline. marine
biologist under a guy and his research team are gearing up for their next dive. they've come to observe the shark and raid populations which have seen an eighty five percent decline in the region. what they're learning is disturbing. where we go first samples we've got going to get shots from the cost of. this part of the brothers and we've got all the organs well we didn't really have to buy anything suspicious but there was there were all certain. on an ordinary dive they descend about fifty meters best been relatively little research on the sea life here and virtually no other studies on diseases affecting creatures like the leopard shark or the short fin mako shark or.
this is part of the pathological collection at the university of sarajevo scientists here study fish such as rays or skates which end up as bycatch in fishing nets. the research as x. ray them take c.t. scans and study tissue samples under the microscope. around ninety percent of the samples showed evidence of disease. this is normal to have up to fifty percent of the firth we can deliver. they have far more than the fifty percent. decide that you can see the whole. they've also found hepatitis and to generative tissue changes the researchers have yet to uncover the cause under a guy says it could take up to a decade to identify the environmental factors that contribute to these diseases.
the town of know i'm is on the adriatic coast it's a popular holiday destination for bosnia and herzegovina. all of the town sewage flows directly into the sea some of it unfiltered. the water. and there's also there's also need for. regulation which will help. one cause for the decline of some species is overfishing the biologist see sustainable fish farms as a possible solution. this one is owned by even comic his family fished here for generations until open water catches declined. our forefathers fished but it was different then they fished for themselves and
even they did not have an outer circle at the market and. that's why we've started . today we can supply all of bosnia and herzegovina with fish. the findings of under his team have raised international concern now to open an ocean research institute in his home country and he hopes that one day biodiversity will return to the. says that it will be as rich in species as this marine aquarium . remarkable story on. leaving it to waste. a story from kenya where secondhand. colorful african fabric being. new bag and wallet it's a simple idea mohamed has turned into a. business here. because doing.
kenyan eco entrepreneur. founded the company. jeans a second life. here in nairobi market he finds used garment to create stylish bags and excess or. every article is unique and reflects its origin. being sold over the internet. the business has a staff of ten employees. and it's sold ten thousand bags since twenty
thirteen. year old jeans. you like them. if you are also doing your bit tell us about. visit our website or send us a tweet. hash tag doing your bit we share your stories. ever heard. growing your own presence of all if so you probably think that. well. draws indoors using up to light rather than sunlight. but is this. doesn't it's going. good for you we went to find out.
fresh lettuce seedlings needing just some light and sufficient heat to get growing and they get both as well as plenty of space in this vertical farm. eighteen hours of light per day and the constant temperature of twenty two degrees celsius. meanwhile but should lettuce is being harvested at the other end of the farmhouse. twenty one days is coming. to complete. the key parameters light intensity nutrient density and the quantity of water plus the time they spend in the sun at the farm. the company harvests one hundred twenty kilos of lettuce per day in its converted warehouse in central hamburg all year round regardless of the weather where. does it isn't really an issue of the cheerio is outdated it's all industrialized today companies have been growing lettuces in
greenhouses for forty years now and there's no alternative when it comes to supplying the mass market at low prices with. this company goes a step or two further than conventional greenhouses nothing is left to chance here the seeds a disinfected before being planted to exterminate any your fungus. because all the nutrients from plants and eventually. strictly controlled artificial lighting it's a complicated and expensive set up. the space light quantity and nutrients have to be calculated precisely. because. we decided to go for baby leaf lettuce instead of butter had let us because it grows faster and requires less energy. cress grows in just six or seven days depending on the bridey it's a question of finding the right balance economically and ecologically. ten canteens
in restaurants in hamburg now there lettuce from the indoor farm it costs between nine and twelve euro's per kilo the third more than produce from southern spain or morocco customers were initially skeptical says restaurant chef benyamin poisoning but they're paying for a superior product hands with no refrigerated transportation the plants retain then that trophy and for. at first it was really hard for us to get people to try the lettuce. we told them this is a pretty far out concept and genuinely different. it's a system you've not seen before says. the company grants only limited access to production also because it's come under criticism for the high energy consumption involved the l.e.d. lighting means a kilo of lettuce needs six or seven kilos watts of power until ready for harvest but the management defends its emissions record.
windier to start like we compare this to a greenhouse when the sun may be free of charge but you also need a cooling system for the roots on the water so the overall energy consumption for greenhouse production is also very high but the critics overlook that here the energy factor is obvious because the l.e.d. lighting is so conspicuous. a number of countries in. the middle east have also shown interest the region's climate is particularly unfavorable for growing lettice pushing up costs for watering and cooling so indoor vegetables could have a very big future in these climate zones. we can also do small vegetables such as peppers and chiles will be trying strawberry soon and basically it could work with any plant although not yet the major crops like wheat maize it's not feasible with our system but lettuce cress herbs and small vegetables are all doable.
new uses for them when the company is currently experimenting with eighty different crop varieties although not all of them have proved worthwhile i mean thirty so far have become marketable lots of these. days in an africa people who rely on firewood to cook and to buy what we have to because all to often. salsas off. where they are. quite expensive a common carrier has found a way to tackle the problem guess what it's encouraging small businesses and even schools to switch to bio guys by helping them install bio gas plants and even more importantly teaching them how to make the most of the technology.
has to be modified by hand. to work. from an established the nonprofit on to. become a real record three years ago. i teach workshop in the capital the l.d. there modifying a portable gas to instead of a gas bottle issued one on bio gas some families in the countryside are already using the system you are doing if you see most family don't use file to get into your house if you go by the your guy system or the rubbish in the house and it in a can get out of the police i didn't just come up with a good result of the cooking gas you have the he said he said i'll come for it and then you are organic my new and theirs is a bio gas digester woman hammad and his team i visited a village north of you are wanting to show farmers how to build and operate a bio gas system when
a production to decompose john to please the gaza now rice and be at it all they have school about three hundred people over the past few months demand for the devices and training is rising still it is sometimes hard to convince people of the advantages of this new technology we need that's peace where it can be practiced shown to people because people want to see but we don't want to listen listen a lot of nothing has been happening so they want to see so are many mass practitioners is to carry out a lot of experiments that the short of the people that this thing works. is installing its biggest facility to date in a corner a small town outside the island day with a large septic tank for the recycling of organic waste. it was commissioned by a catholic seminary there at a cost of about two and a half thousand euro's. human kitchen and garden ways to be fed into the tank
the resulting bio gas will be used in the seminary kitchen which feeds the two hundred students. well of it as how the seminary with the project as a consultant should be looking for the whites technology for a long time. isn't a problem on team while they even sent me to china to see if i could source the equipment there to produce bio gas. that we discovered that there was already an enterprise in cameroon itself that makes what we need. so we ordered it through cam come on. record was already installed a number of bio systems both portable and fixed but not many people or institutions incomer all of our way out of bio gas as an eco friendly energy source we intend to promote this thing in the world but you know we're no finals no more to no they
need you know support it's very very difficult to create awareness the government development plan cameron vision twenty thirty five m.c.g. promoting targeted religious but so far the biogas plays a tiny role in the energy mix. for years mozambique was ravaged by civil war and conservation was not top priority but the country he's actually rich in natural resources and boasts of some sizable national parks a delegation of german scientists is now working with african partners to breathe new life into the national park in solving was a big and make it more attractive for the tourists let's see how much of a chipman they made. ranges of the bahai national park taking a group of scientists from germany on safari. it's
a huge grassland park with wetland areas that are paradise. stretching seven thousand square kilometers the park is a home for countless pelicans. for which the park is best known for the ostrich there the only ostrich is in mozambique. the group has found something else of interest if not bigger do this is an elephant corridor. when the elephants pass through the area they leave their dung be highly. these days the park has no large animals of its own lions buffaloes and rhinos were driven away first by the civil war then by poachers or by going or form it's not that poachers need food that's not a problem right now people have enough to eat. they set these traps because they want to make money. so the park has been
a protected area for more than forty years there are stiff penalties for coaches but illegal killing of animals remains a problem it disrupts the ecosystem in the reserves the ranges document their findings and remove the carcasses. while driving to some of the villages situated inside the park it becomes clear there are other problems these a sacks of charcoal made illegally from wood and confiscated by the ranges. i was crushed but when it does the villagers cut down the trees and destroy the natural habitat the animals are forced to flee and end up entering the residential areas which leads to new problems the animals' habitat is being destroyed. there are twenty villages in and around the park home to nearly six thousand people many residents content to stand the need for such strict conservation laws. so how can the national park foster better relations with local residents that's the question
that interests the great from germany together with the ranges they want to convey the message that the park is keen to support local residents one man cites the example of another park nearby one shekel feet one at the end of each year the park gives twenty percent of its income to the local community they can then use the money to buy something for the benefit of the entire village. that would be a good model here and help local people to see tourism as an opportunity to earn money visitors from abroad would also get a taste of the traditional lifestyle of people living in the park. this family profited from the german group and enjoyed the encounter to ok nothing out clearly out of it out. but it's all early days yet. it's a drop in the ocean and obviously we're not yet teaching people how to preserve their
environment. the volunteers are committed to a long term partnership with the national park and the local community they want to know what other activities could interest visitors waiting for where. it's just what we need to preserve this to attract tourists. we'd like to offer something that other reserves don't have so that people say if we want to see that we need to go to buy you know just so for them to debate it. a nighttime safari is one idea the park specializes in small animals here it's not the big five the visitor is unlikely to see that from antelopes on a rich variety of banks. but drops it out for this edition of eco at africa if you have to fight about more take a look at our website my name is cheryl mani every good buy from me here in nairobi kenya and i'm now signing up from our border in nigeria don't forget the tuning
