vaigach island ( 3,383 sq km ) was chosen as a model area for the study of climate change and its impacts in the arctic . vaigach is the one of the keypoints of the north sea route because ships can reach the seas of siberia from the west only by two straits : karskiye vorota ( to the north of vaigach ) and yugorsky shar ( to the south of vaigach ) . it is located between the archipelago of novaya zemlya and the mainland in the subarctic natural area on the border of the arctic- european and arctic- asian island provinces of the arctic ocean . the climatic conditions of vaigach are more severe than in the south island of novaya zemlya that is located to the north of it , as the southwestern part of novaya zemlya is affected by the warm western novaya zemlya current and the east novaya zemlya current during the cold season . this brings ice from the kara sea , clogging the karskiye vorota , and yugorsky shar straits . the grass cover of vaigach is peculiar to northern arctic tundra , there are many small lakes and marshes , and rivers  the rapids are deeply cut into the surface ( 8) . vaigach on the map of the barents euro - arctic region in august 2010 , an expedition was organized to vaigach island run by barentsevomorskoe branch of the world wildlife fund ( wwf ) , led by oleg k. sutkaitis . along with the biological research into changes to the bird and sea - mammal populations , there was an attempt to study the perception of climate change by the indigenous people , namely the nenets of varnek , who have the only settlement on this island . the authors designed a questionnaire used during the survey and which residents of the settlement varnek answered . the results were compared with historic data , archive materials , and more broad topics , connected with recent developments in the arctic . varnek was listed as having 101 people in august 2011 ( see table 1 ) . age - sex structure of population of varnek ( compiled from the household books ) in varnek , there are 16 buildings , and 24 families live there . coal for heating is delivered right into the backyard of houses . in front of the buildings , there are garages for  buran ( winter motor sledges ) and dog huts ( insulated buildings for hunting and sled dogs ) . the village has a shop , club , medical - obstetric stations , and a bakery . the village is lit by electricity from 7.00 am to 2.00 am by a diesel generator . the presence of tundra , the large numbers of marine animals ( seals , walruses ) , and birds ( geese ) have shaped the features of the traditional economic system of the nenets living on vaigach . reindeer husbandry plays a lesser role on vaigach island compared with the continental tundra nenets . there are only three men working with reindeer on vaigach island : the foreman and two herders . there are about 1,000 reindeer in a herd ( in the 1970s the herd was up to 1,700 reindeer ) . free pasture is practiced throughout the island ( wolves are rare on the island ) . hunting and fishing play a very significant role in the economic activity of the nenets people on vaigach island . all the men of the village are hunters ( the boys start hunting at the age of seven ) . the most popular hunting season is the spring hunt for the arriving birds and then the summer / autumn hunt  for molting birds . the family collects about 100120 eider eggs annually ( in this case one egg is usually left in the nest ) in the spring season . the winter hunt is for marine animals : usually seals ( to feed the dogs ) . in varnek to feed 812 dogs over the winter , it is necessary to catch about 3040 seals . professional fishermen in the village ) and catch omul ( arctic cisco ) , trout , cod , and smelt . in the village , there are about a dozen nets and one traditional ryuzha ( fishing trap ) used for many centuries . there is one nenets master making boats ( in the old so - called pomor fashion ) from wood and metal from crashed military aircraft . in summer , the nenets of varnek collect russian root , snowdon roses , or rosewort ( rhodiola rosea ) known in russian as zolotoy koren (  gold root ) , mushrooms , and cloudberries . a family can collect up to 50 litres of cloudberries that are stored in wooden barrels . in general , at the present time , the village of varnek constitutes a special kind of nenets port economy with elements of the influence of the culture of the russian pomors ( the original settlers on the white sea coast ) and the preservation of traditional attitudes toward reindeer . the activities on the north sea route have a great impact on the economic activities and the household life of the varnek nenets population as an important segment of this is the yugosky shar strait . for the period of 10 days that our expedition stayed in varnek , the settlement was visited by a barge with two tugs , the ship of the moscow state university scientific expedition , a trimaran from the norwegian circumpolar expedition , a tanker , and two vessels . excluding the trimaran from norway fish catch ( omul , char ) , and reindeer and polar fox skins ( and illegally harvested skins of polar bears ) , and cloudberries are collected in exchange for alcohol . such an exchange has negative social consequences for the village , transforming the economic direction and nature of the environmental population . natural resources are exploited not only for local consumption but also in such quantities that they are capable of damaging the life of the nenets community on the island . under market conditions , the traditional nature management is transformed according to the demands of the visitors and the nenets sometimes even break the hunting rules and become poachers . the inhabitants of the village of varnek comprise 101 persons , including 59 adults , 42 children , and 18 students ( studying at a boarding school in the mainland village of karatayka ) . during the survey in the village , there were some people who did not participate : about 20 adults were absent and 6 other adults refused to take part in the survey . the presence of tundra , the large numbers of marine animals ( seals , walruses ) , and birds ( geese ) have shaped the features of the traditional economic system of the nenets living on vaigach . reindeer husbandry plays a lesser role on vaigach island compared with the continental tundra nenets . there are only three men working with reindeer on vaigach island : the foreman and two herders . there are about 1,000 reindeer in a herd ( in the

participate : about 20 adults were absent and 6 other adults refused to take part in the survey . the respondents believed that the most important activities for their own survival were traditional nature use fishing ( 14 persons ) , hunting ( 12 persons ) , and reindeer breeding ( 11 persons ) . in addition , the villagers described trade and exchange ( six persons ) , picking berries and mushrooms ( four persons ) as essential for their survival . according to respondents answers most respondents said that over the past 5 years , the climate had became colder , but two men involved in fishing , however , had noticed 1 ) the evaluation of seasonal climate changes . seasonal climate changes according to the respondents evaluation were as follows : winter was colder and longer , and summer colder and shorter . with respect to changes in the spring period , the respondents had different , even sometimes contradictory opinions . obviously , the growing season had become longer because more southern species of plants were now able to survive on vaigach . however , the human impressions of the seasons were different because the spring time started earlier , but the spring itself seems colder ( comments by l.r.lukin , institute of ecological problems of the north , ub ras ) . the island 's inhabitants estimated climate change by observing the melting snow , the arrival , and disappearance of birds ( including geese ) , and the change in vegetation . respondents noted the emergence of new species on the island of animals , plants , insects that they could not identify (  i can not call them anything,  do not know the name ) . among the known species were crows , whereas  before there were none, and an increase in wasps . residents have noted changes in vegetation , it  has more flowers,  the bushes spread, and pointed out that the  lakes dried. climate change has affected the lives of the islanders , in the opinion of half of respondents ( 16 persons ) , others do not notice this effect ( 9 persons ) , or found it  difficult to give an answer ( 5 persons ) . despite the fact that the survey results indicate a decrease in the standard of living on the island historically , vaigach is a holy land of the nenets people : in the nenets language , the island 's name is : hehe ya or hebidya ya . it contains many sites , sacred places of tribal and personal shamanic significance ( 9 ) . since ancient times , the nenets from the continental tundra have gone on pilgrimages to vaigach . they gathered their reindeer that then crossed the yugorsky shar strait by walking across the ice or by swimming . the sledges with a passenger were tied to the reindeer that swam across the strait pulling them . the sacred status of vaigach has limited economic significance for the nenets on the island . however , the appearance of the hebidya ya , the russian fishermen , who hunted sea mammals and molting birds initially caused conflict with the nenets . r. jones , a member of s. borrough 's expedition in 1556 wrote about vaigach :  wild samoyeds live there , not allowing russians to land ( 10 ) . vaigach island is now a sanctuary and operates as a place of worship for nenets living in the far north . in the nenets beliefs , fog , wind , rainfall are a form of manifestation of the spirits relationship to actions : people 's behavior . below is a fragment of one of the legends of vaigach , as submitted by residents of the island : 
 i learned that there is an inscription on the semiliky idol ( spirit with seven faces )  translated into russian :  in 1988 , six grandchildren will be born of vesako idol. there should be six boys in one family line ... according to the belief of the villagers of varnek and my own observations , one of those six grandchildren controls the weather . (  )  archaeologists took the idol to one of the museums in moscow ... during this time , while vesako was absent , on vaigach there were strong blizzards , hurricanes , sweeping everything in their path , but when he was brought back , the weather calmed down.11

backgroundarctic climate change is already having a significant impact on the environment , economic activity , and public health . for the northern peoples , traditions and cultural identity are closely related to the natural environment so any change will have consequences for society in several ways.methodsa questionnaire was given to the population on the vaigach island , the nenets who rely to a large degree on hunting , fishing and reindeer herding for survival . 
 semi - structured interviews were also conducted about perception of climate change.resultsclimate change is observed and has already had an impact on daily life according to more than 50% of the respondents . 
 the winter season is now colder and longer and the summer season colder and shorter . 
 a decrease in standard of living was noticeable but few were planning to leave.conclusionclimate change has been noticed in the region and it has a negative impact on the standard of living for the nenets . 
 however , as of yet they do not want to leave as cultural identity is important for their overall well - being .
