Soybean rust was first found on state in 2001/2002 crop season. Since then it has been causing major losses in soybean production. Many methods are indicated to manage the disease. An important disease regulatory method is the fallowing ( vazio sanitário) , and it is unknown whether the method is being effective in reducing rust intensity throughout the years. Therefore, to assess the effect of fallowing in the disease intensity, we analysed data collected from 2008 to 2012 in producing municipalities of Mato Grosso, regarding both the enforcement of soybean following and the data of occurrences of rust. The implementation of fallowing has been effective in reducing rust intensity in all producing regions, as well as to move the first disease ccurrence from November-December to January-February. Rust tis being firstly reported when the plants are in the beginning seed stage (R5), and the earlier plantings are the main source of inoculum for late plantings. Official monitoring is helping maintaining more than 88% growers in the fallowing program to control the soybean rust. / A partir dos anos 1970 ocorreu a expansão da cultura da soja para o cerrado, e o estado de Mato Grosso tornou-se, desde o ano 2000, o maior produtor nacional da oleaginosa. Desde a safra 2001/2002, quando foi detectada pela primeira vez, a ferrugem asiática tem causado grandes perdas. Entre as medidas de controle da doença, inclui-se a adoção do vazio sanitário, mas desconhece-se o efeito da medida em reduzir a intensidade da doença. Assim, analisaram-se dados coletados de 2008 a 2012 nos municípios produtores do Mato Grosso, coletados na fiscalização do vazio sanitário da soja, e os de ocorrências da ferrugem, coletados pelo consórcio antiferrugem, para avaliar o efeito da implementação do vazio sanitário na incidência da ferrugem asiática. A implantação do vazio sanitário da soja reduziu e tem mantido baixas as ocorrências da ferrugem, em todas as regiões produtoras, além de deslocar o período de ocorrências da doença, de novembro e dezembro para janeiro e fevereiro. As primeiras ocorrências acontecem com a planta no estádio de granação (R5), sendo os plantios precoces a principal fonte de inóculo para os plantios tardios. A fiscalização tem auxiliado a manter a adesão dos produtores ao programa de controle da ferrugem asiática da soja em índices superiores a 88%.

This study deals with the current demographic situation of the Russian Far East and tries to assess the main patterns of migration in the region. The work is structured in five chapters. The first chapter aims at defining the Russian Far East geographically and concentrates on the most important features of its economy. The second chapter is devoted to region's rapid depopulation since the beginning of 1990s. This part analyses the dominant demographic trends within the district and tries to describe the prevalent patterns of migration on its territory. The third chapter presents a brief historical overview of the colonization and resettlement policies towards the Russian Far East. The main goal of this part is to evaluate the overall effectivity of both tsarist Russia and the Soviet Union in their efforts to populate their easternmost periphery and secure the border with China. The fourth chapter deals with the problem of Chinese migration to the Russian Far East. The emphasis is put on the myth of China's "demographic expansion" and also on the question of possible benefits of drawing in more Chinese workforce in the foreseeable future. The last chapter analyses the current state program designed to attract large numbers of ethnic Russians from abroad and settle them in regions considered as...

The aim of the work is to introduce a different way of looking at the process of urban planning in the so-called shrinking cities. The plan of endless development is questioned. The stagnation scenario, as a form of conservation, is presented as a certain level of natural development of the city. The potential of forgotten parts of the city is emphasized. The postcultural landscape meets man.

Since the 1980’s there has been a neoliberal development in society and politics, especially inthe Western world, where the welfare state has taken a step back and new ideas such asmarket and privatisation has had a breakthrough within the public sphere. Under theneoliberal development there has been an ongoing urbanisation but also a depopulation inapproximately half of the Swedish municipalities. Municipalities, which can be understood asthe lengthened arm of the welfare state, which have been affected by depopulation hastherefore had it much more difficult fullfilling their welfare duties due to the negative effectsof depopulation. Despite structural population changes both growing and decreasingmunicipalities tend to strive for growth, something that is not one of the municipalities tasks.It can be understood as a part of a neoliberal context where a so called market based ideologycan be found among municipalities who’s trying to create growth through its place brand. Oneof the municipalities which has experienced a considerable depopulating development isHagfors kommun (municipality), a municipality which can also be understood as anillustrative example of a depopulating municipality. The purpose of this thesis is therefore toexamine if there is a tension between the municipality Hagfors as a welfare organ and aneoliberal hegemony in society, and if there has been a neoliberal development over time. Inorder to carry this thesis out a qualitative method is used with discourse analysis which stemsfrom Laclau’s and Mouffe’s discourse theory and selected terms suited for the thesis’ scopeand purpose. The material consists of developmental documents from Hagfors kommun. The analysis treats meaning-making and expression as something that can be understoodwithin a neoliberal discourse as well as a welfare discourse. The analysis is lead by especiallyLaclau’s and Mouffe’s discourse theoretical term hegemony and its sub-terms. It appearsfrom the analysis that a neoliberal discourse can be found and is incused in the documentsfrom both points in time, 2002 and current documents from 2017 and 2019, and that it hasgrown stronger. The municipality has gone from hegemonising its role as a welfare organ anda welfare discourse to hegemonising itself as a place brand and hence hegmonising aneoliberal discourse. The conclusion as to whether there was a tension between themunicipality as a welfare organ and neoliberalism is that since the municipality chooses tohegemonise itself as a place brand and a part of a neoliberal context in contrast to trying toadapt to the negative development and minimising its negative consequenses, there is atension between the municipality as a welfare organ and neoliberalism. / Sedan 1980-talet har det skett en nyliberal utveckling i samhället och politiken, framförallt ivästvärlden, där välfärdsstaten tagit ett steg tillbaka och nya idéer som marknad ochprivatisering har fått genomslag inom det offentliga. Under den nyliberala utvecklingen hardet pågått en urbanisering men också en avbefolkning för ungefär hälften av Sverigeskommuner. Kommuner, som kan förstås som välfärdsstatens förlängda arm, som drabbats avavbefolkning har därför fått det allt tuffare att fullgöra sitt välfärdsansvar med hänsyn tillavbefolkningens negativa effekter. Trots strukturella befolkningsförändringar tenderar bådeväxande och minskande kommuner att sträva efter tillväxt, något som egentligen inte ärkommunens uppgift. Det kan förstås som en del av en nyliberal kontext där en så kalladmarknadsbaserad ideologi återfinns bland kommuner som försöker skapa tillväxt genom sittplatsvarumärke. En av de kommuner som drabbats av en betydlig avbefolkning är Hagforskommun, en kommun som också kan förstås som ett illustrativt exempel av en avbefolkandekommun. Syftet med denna uppsats är därför att undersöka om det finns en spänning mellankommunen Hagfors som välfärdsorgan och en nyliberal hegemoni i samhället, och om detskett en nyliberal utveckling över tid. För att genomföra uppsatsen så används en kvalitativansats med diskursanalys som utgår ifrån Laclaus och Mouffes diskursteori och utvaldabegrepp lämpade för uppsatsens omfång och syfte. Materialet består av utvecklingsdokumentfrån Hagfors kommun. I analysen så behandlas meningsskapande och uttryck som kan förstås inom såväl en nyliberaldiskurs som en välfärdsdiskurs. Analysen vägleds av framförallt Laclaus och Mouffesdiskursteoretiska begreppet hegemoni och dess underbegrepp. Det framgår av analysen att detfinns en nyliberal diskurs i dokumenten från båda tidpunkter som präglar dem, 2002 ochaktuella dokument från 2017 och 2019, och som har förstärkts över tid. Kommunen har gåttfrån att hegemonisera sin roll som välfärdsorgan och en välfärdsdiskurs till att hegemoniserasig självt som ett platsvarumärke och därmed hegemonisera en nyliberal diskurs. Slutsatsenrörande om det fanns en spänning mellan kommunen som välfärdsorgan och nyliberalism äratt då kommunen väljer att hegemonisera sig själv som ett platsvarumärke och en del av ennyliberal kontext i motats till att försöka anpassa sig till den negativa utvecklingen ochminimera negativa konsekvenser utav den, så finns det en spänning mellan kommunen somvälfärdsorgan och nyliberalismen.

This study deals with municipal planning in municipalities that has a declining population, often referred to as shrinking municipalities. Data collection was done by interviews with civil servants tasked with planning in municipalities. The interview’s purpose was to gather knowledge on the experience of working within a shrinking municipality. The civil servants interviewed worked within Laxå, Sävsjö, Vimmerby, Hultsfred and Valdemarsvik municipality. The data from the interview was analyzed in relation to earlier research about societies and region with a decline in population and has its theoretical framework in the growth-critical theory degrowth. The results that’s the basis for analysis is structured after four different themes. These themes touch on the subjects of challenges, possibilities, strategies, activities as well as attitude in relation to the civil servants’ experiences.  The analysis of the results ends up problematizing the growth paradigm since shrinking municipalities becomes disadvantaged by creating growth-oriented strategies. Furthermore, the results show how creative solutions to counter or alternatively adapt shrinkage remains absent in shrinking municipalities due to a lack of a long-term perspective in planning. / Denna studie behandlar samhällsplanering i kommuner med en minskande befolkning, ofta benämnt som krympande kommuner. Materialinsamlingen till studien genomfördes med intervjuer där tjänstepersoner som jobbar med samhällsplanering tillfrågades. Syftet med intervjuerna var att ta in tjänstepersonernas erfarenheter om att jobba i en krympande kommun. Tjänstepersonerna som intervjuades tillhörde Laxå, Sävsjö, Vimmerby, Hultsfred och Valdemarsvik kommun. Intervjumaterialet analyserades i relation tidigare forskning om minskande samhällen och regioner med teoretisk utgångspunkt i tillväxtkritiska teorin degrowth. I resultatet presenteras det material som vidare ligger till grund för analysen strukturerade efter fyra olika teman. Dessa teman berör utmaningar, möjligheter, strategier, verksamheter och inställning i förhållande till tjänstepersonernas erfarenheter. Analysen av resultatet leder i slutet till en problematisering av tillväxtparadigmet då minskande kommuner missgynnas av att utforma tillväxtorienterade strategier. Vidare påvisade även resultatet att kreativa lösningar för att motverka alternativt anpassa krympande uteblir i krympande kommuner till följd av brist på långsiktigt perspektiv i samhällsplaneringen.

La technique d’empreinte génétique par rep-PCR, qui utilise des séquences d’ADN répétitives, a été utilisée pour mettre en évidence la présence de groupes d’Escherichia coli signatures pour divers poulaillers et d’évaluer leur évolution suite au détassement. L’amorce (GTG)5 a été utilisée pour générer des empreintes d’ADN de 522 isolats provenant de 7 poulaillers échantillonnés deux fois : juste avant et 5 jours après le détassement. Les empreintes d’ADN ont été analysées selon l’algorithme de correspondance de bandes de Jaccard. Les analyses de Jackknife des coefficients de similitude ont révélé qu’entre 73% et 93% des isolats ont pu être correctement regroupés selon leur poulailler d’origine. Un dendrogramme construit à partir des coefficients de similitude de Jaccard a groupé les isolats dans 42 grappes avec près de la moitié dans une seule grappe. Environ 80% des isolats ont été groupés dans les 6 plus grosses grappes. Quatre de ces grappes été constituées majoritairement d’isolats provenant d’un seul site. Ces grappes pourraient être des grappes signatures qui permettraient d’identifier des poulaillers en particulier. La comparaison des nombres de grappes présentes avant et après le détassement a révélé une variabilité de l’impact du détassement sur les populations fécales d’E. coli. Pour certains sites, il y avait peu d’agrégats présents tant avant qu’après le détassement alors que pour d’autres sites c’était le contraire. Quoique plus de recherches soient nécessaires afin de valider les conclusions, nos résultats suggèrent la présence de sous-populations signatures d’E. coli pour certains poulaillers et une réponse variable à l’effet du détassement. / Rep-PCR genomic fingerprinting, which uses repetitive intergenic DNA sequences, was investigated as a mean to identify signature pattern of chicken fecal Escherichia coli populations and evaluate their changes over time. The (GTG)5 primer was used to generate DNA fingerprints from 522 isolates originating from 7 chicken houses just prior to, and five days after, thinning. The DNA fingerprints were analysed by using the Jaccard band-matching algorithm. Jackknife analysis of the resulting similarity coefficients revealed that between 73% and 93% of the isolates could correctly be grouped in their house of origin. A dendrogram constructed by using Jaccard similarity coefficients grouped the isolates in 42 clusters with approximately half of them in the same cluster. Out of the 6 largest clusters, containing 80% of all isolates, 4 consisted mostly of isolates coming from only 1 house. These clusters could represent signature clusters identifying specific houses. A comparison of the number of clusters present before and after thinning for each house revealed a substantial difference in the behaviour of the fecal E. coli. For some houses, there were few clusters represented both before and after thinning, with a high number of new clusters appearing after thinning whereas in other houses, the contrary was observed. Our results suggest the presence of a signature subpopulation in some chicken houses and a variable response of the E. coli population to the effect of thinning.

<p>U radu se razmatraju demografski problemi regije Hercegovine s posebnim osvrtom na Zapadnohercegovačku županiju te njihov uticaj na morfolo&scaron;ko-funkcionalne promene naselja (gradova s pripadajućim naseljenim mestima) u pedesetogodi&scaron;njem &nbsp; vremenskom periodu,&nbsp; s naglaskom za vremenski period od&nbsp; 1961.&nbsp; do 2011. godine. &nbsp;Područje koje se analizira u ovome radu odnosi se na područje koje je funkcionalno vezano za Zapadnohercegovačku županiju, jednu od deset kantona/županija u FBiH. &nbsp;Proučavani prostor obuhvata 100 naseljenih mesta (četiri gradska naselja). U radu se analizira demografski razvitak, te međusobna povezanost demografskog i socio-ekonomskog razvitka naselja na području&nbsp;Zapadnohercegovačke županije te funkcionalno-morfolo&scaron;ke promene naselja. Zapadnohercegovačka županija tradicionalno je emigracijsko područje koje&nbsp;je već decenijama zahvaćeno procesom depopulacije. &Scaron;ire je područje značajnije počelo&nbsp;&nbsp; izumirati nakon Drugog svetskog rata, dok su&nbsp; gradski prostor i njegova okolina, inače centri imigracija, stvarali područja i žari&scaron;ta ekonomskog i op&scaron;teg razvitka Zapadnohercegovačke županije.&nbsp;Depopulaciju je u &nbsp;naseljenim mestima planinskog&nbsp; dela Županije (brdski prostori) pratilo napu&scaron;tanje tradicionalnih privrednih aktivnosti (u prvom redu zemljoradnje&nbsp; i stočarstva), do&scaron;lo je do pojave socijalnog pusto&scaron;enja, promena u krajoliku te&nbsp;izumiranja pojedinih naselja. Najznačajniji uticaj imali su znatno iseljavanje&nbsp; stanovni&scaron;tva u drugoj polovini 20. veka, direktne i indirektne posledice dvaju svetskih ratova, zatim različite epidemije, agrarna reforma, ekonomske krize koje su se u&nbsp;nekoliko navrata javljale tokom 20. veka. Tome su&nbsp;&nbsp;&nbsp; pridoneli i ostali faktori, kao &scaron;to su ekonomska emigracija od sredine &scaron;ezdesetih godina 20. veka, urbanizacija, industrijalizacija te snažan razvitak sredi&scaron;njih i prigradskih &nbsp;naselja. Deagrarizacija i&nbsp;deruralizacija, tranzicija nataliteta, rat na području Bosne i Hercegovine u prvoj polovini devedesetih godina 20. veka, te neprimerena populaciona politika,&nbsp; ostavile su traga na ovim područjima.&nbsp; S obzirom na dominantne demografske trendove u&nbsp;Županiji može se pretpostaviti da će reprodukcija, odnosno obnavljanje radne snage u budućnosti biti smanjeno. Naime, na navedenu će činjenicu uticati smanjenje stope prirodnog kretanja stanovni&scaron;tva prisutno na području &nbsp;Zapadnohercegovačke županije&nbsp; već nekoliko decenija, &scaron;to znači da će se smanjenje broja mladih stanovnika negativno odraziti na obim radne snage.&nbsp;</p><p>Depopulacija ima negativne posledice na funkcije naselja te na morfologiju naselja. U pojedinim naseljima je do&scaron;lo do promene u njihovoj strukturi i obliku osnove naselja, a gotovo sva naselja u Županiji imaju promene u fizionomiji.</p> / <p>This paper discusses the demographic problems of the region Herzegovina with special reference to the West Herzegovina County and their impact on the morphological and functional changes of settlements (cities with the belonging populated areas) in fifty years time, with particular emphasis on the period&nbsp;from 1961 to 2011. The area that is analyzed in this paper refers to the area that is functionally related to the West Herzegovina County, one of ten cantons/counties in the Federation of Bosnia and Herzegovina. The studied area covers 100 settlements (four &nbsp;urban settlements). The paper analyzes the demographic development andinterconnection of demographic and socio&nbsp; -economic development of settlements &nbsp;in theWest&nbsp; Herzegovina&nbsp; County and functional and morphological changes of settlements.</p><p>West Herzegovina County&nbsp; is a traditional&nbsp; emigration area that has been affected by the process of depopulation for decades. Wider area&nbsp;began depopulating after World &nbsp;War II, while the urban area and its surroundings,&nbsp; which arein fact&nbsp; immigration centers, were creating areas and foci of economic and general development of West Herzegovina County. Depopulation in settled places of mountainous part of the County (mountain areas)&nbsp; was followed by the abandonment of traditional economic activities (primarily agriculture and animal husbandry).&nbsp;There&nbsp; was&nbsp; considerable social fallow as well as changes in the landscape and the extinction of some settlements. The emigration in the second half of the 20th century, the direct and indirect consequences of the two world wars, then various epidemics, agrarian reform, &nbsp;economic crises that have occurred on several occasions during the 20th century had &nbsp;the most significant influence on the depopulation in this area. Some &nbsp;other factors, such as the economic emigration from the mid-sixties of the 20th century, urbanization, industrialization and a strong development of central and suburban areas, contributed to this as well. Deagrarization and deruralization, fertility transition, the war in Bosnia and Herzegovina in the first half of the nineties of the 20th &nbsp;century and inadequate population policy made their mark in this area.&nbsp;Concerning the dominant demographic trends in the County it can be assumed that the &nbsp;reproduction or recovery of the&nbsp; labor force in the future will be reduced. Namely, this fact will be&nbsp; affected by&nbsp; reduction in the rate of natural population&nbsp; growth that has been&nbsp; present in the area of&nbsp; West County for several decades, which&nbsp;means that the reduction in the &nbsp;number of young&nbsp;&nbsp; people has&nbsp; a negative impact on the volume of the &nbsp;labor force.</p><p>Depopulation has negative effects on the function of the village and the morphology of&nbsp;settlements. In some villages there is a change in their structure and form of the basics of the village, and almost all the villages in the County have a change in the &nbsp;physiognomy. The concentration of population and economic activities in urban and suburban area had also influence on the&nbsp; landscape change.&nbsp;Demographic processes, that have occurred in West County, affected the socio&nbsp; -&nbsp; economic,physiognomic and functional transformation of urban neighborhoods and some parts of the County.</p>

I have always known that I would leave my hometown. Always been told that it is too boring for a dreamer, that it is a place where all ambition wanes. None of my childhood friends stayed; we all moved towards something bigger, something better- towards opportunities. We all moved, to some degree, south. Depopulation of rural communities is not unique to Norrland but Tankebanan investigates this topic within the context of the northern inlands of Sweden, exploring its industrial history and local conditions. The project aims to create an infrastructure strengthening the social and cultural capital of the inland by generating educational, entrepreneurial and identity building activities in the region. The site of the project stretches along Malmbanan, the railway transporting iron from the industries of the inland to the ports of Narvik and Luleå. The tracks are a physical trace of the industrial history of the region and therefor a suitable location for the project that proposes three fixed nodes along the railway, each targeting one specific aspect of the knowledge network. The nodes are Creation in Abisko, Education in Kiruna and Entrepreneurship in Gällivare.Tankebanan reprograms old carbarns within the towns into hubs of activity and optimism, aiming to challenge the pessimism often connotated with the region, causing people to leave. It aims to turn struggles into challenges and encourage young people to see the potential within themselves and within Norrland. This phase of the project explores the node of Education in Kiruna, which proposes an alternative university for those who wish to obtain a degree without leaving the north. The program consists of a public library and train station, educational facilities, conference rooms and accommodation for long distance commuters. It is hosted within a modular system, relating to the module of the train car and extending the network of the rails into the building.

Le monde rural gabonais est un espace en grande partie vidé de ses populations, soumis depuis longtemps aux pressions de l’exploitation forestière et, depuis une vingtaine d’années, à une politique de conservation très volontaire. Nous avons voulu étudier l’impact de ces pressions sur le monde rural contemporain en nous centrant plus particulièrement sur les aires de conservation. C’est dans la province de l’Ogooué-Ivindo, autour de trois parcs nationaux (Ivindo, Mwagné et Lopé), que nous avons examiné les activités de conservation, de production, les acteurs impliqués ainsi que les conflits qui en résultent. En dépit d’une histoire largement défavorable au monde rural, en dépit aussi de la mauvaise répartition des richesses, des infrastructures et des services, profitant presqu’exclusivement aux villes au détriment des zones rurales, et en dépit enfin de politiques de conservation très contraignantes pour les populations rurales, les villages continuent à exister – en grande partie grâce à la tradition. Les solutions proposées telles que l’attribution des forêts communautaires initiée récemment par l’état gabonais, peuvent-elles permettre de raviver les villages et de faire participer les populations rurales au processus de développement de leurs localités ? Au-delà de cette question, cette thèse permet d’engager des réflexions sur des actions possibles pour éviter l’extinction des villages gabonais. / Gabonese rural world is an area largely emptied of its populations, subjected for a long time to the pressures of the forestry development and, for about more than twenty years, to a very voluntary conservation policy. We have wanted to study the impact of these pressures on the contemporary rural world by focusing our work particularly on the conservation areas. It is in the province of Ogooué-Ivindo, around three national parks (Ivindo, Mwagné and Lopé) that we examined the activities of conservation and production, the actors involved as well as the conflicts which result from them. The history widely unfavorable to the rural world, the unequal distribution of wealth, infrastructures and services, benefiting almost exclusively the cities to the detriment of the rural areas and the conservation policies too binding for the rural populations have made it difficult for villages to survive. In despite of all this, they still exist - largely thanks to the local tradition. But, can possible solutions such as the attribution of community forests, introduced recently by the Gabonese state, bring villages back to life and make rural populations participate in the process of developing their localities? Beyond this question, this thesis seeks to initiate a process of reflection on possible actions to stop the extinction of the Gabonese villages.
