Strategic planning for wood farming development (Case study: Urmia)Nezhad, S. Khayati, Hosseinzadeh, O., Hajjarian, M., Abdi, M. Reza 04 March 2017 (has links)
Yes / Wood farming is one of the strategies of agricultural development programs to reform unsustainable exploitation of natural resources. Poplar is one of the known species for wood farming in the country. This species is fast-growing and has numerous Colognes has the ability to adapt to different climatic conditions. Fast growth, good economic returns and traditional agricultural knowledge, favorable habitat to agriculture are advantages of poplar for agricultural development. However, the result of previous studies indicates existing barriers to the development of plantation and its development need strategic planning. What seem essential today are strategies to overcome these obstacles. Accordingly, this present study with a holistic view trying to identify the strengths, weaknesses, opportunities and threats of poplar farming. And the most appropriate strategies for the development of poplar farming in Urmia have offered. This research was a Field study and conducted using questionnaires. In this study, strategies were defined using SWOT analysis and the strategies were prioritized using analysis network process. The results showed the history of poplar farming in this region is the most important benefit to development and the many uses for poplar wood is the next priority. Increasingly replacement of poplar farming with alternative cultures is one of the main weaknesses of poplar farming development in this region. After that long return of profitability in poplar farming is the second priority. The most important opportunities for the development were the development of credit specialists to support of poplar farming and the most important threat was lack of annual financing of farmers. Also the results of strategic prioritization showed, Modern irrigation methods to reduce water consumption and planning to teach correct principles of technical planting, farming and harvesting are considered as the most important strategies.

Spatiotemporal Analysis of Aerosol Over A Major Salt Lake Region: Case Study of Lake Urmia In IranKhaghani, Ali, Khaghani, Ali January 2017 (has links)
Lake Urmia (LU), which once had been the second largest hypersaline lake in the world, and greatest in the Middle East, has undergone severe environmental changes during recent years that have led to widespread desiccation. These changes have converted the lakebed into a significant Aeolian mineral source, which promotes aerosol plumes that can seriously impact downwind regions. A question remains as to how significant emissions are from LU as compared to others impacting the West and East Azarbaijan provinces encompassing LU. This study uses daily Aerosol Optical Depth (AOD) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) between 2001 and 2015 to show that AOD levels are significantly larger in the latter half of the study period (2008-2015) with AOD values in the West consistently being lower but approaching those of the East with time owing to a combination of increasing emissions from the West province and neighboring areas. While the interannual AOD profile over Azarbaijan resembles that of Iraq owing to transported dust, signatures of the local impact of increasing emissions is evident over the 15-year time period, especially in the months outside of the peak dust season (January, February and October) and on the immediate periphery of LU. Consequently, the spatial profile of AOD over Azarbaijan is not uniform but with distinct hot spot. The onset of the spring AOD ramp-up over Azarbaijan is shown to have started earlier (in February) when comparing 2009-2015 versus earlier years. Correlative analysis confirms that AOD is related to factors promoting dust emissions but also reveals that smoke contributes to AOD over Azarbaijan during the summer months.

Analyzing multilingual settings : a domain analysis perspective / Les sociétés plurilingues : un regard sous l'angle de l'"analyse de domaine"Fereidoni, Javid 06 January 2012 (has links)
La présente étude vise à analyser la situation de plurilinguisme d’©rumiyeh, a partir d’une perspective d’<< analyse dedomaine >> (domain analysis). Trois minorités ethniques, linguistiques et religieuses vivent dans la ville, à savoir lesTurcs, les Kurdes et les Arméniens, qui s’expriment respectivement en turc, kurde et arménien. La langue nationale dupays, l’1ran, est le persan. Naturellement, la population de la région grandit avec deux ou trois langues.Pour cette étude, 900 questionnaires ont été recueillis dans toute la ville et 681 ont été sélectionnés de manière aléatoire(328 Turcs, 214 Kurdes et 139 Arméniens). Les questionnaires ont été élaborés essentiellement à partir du Modèle deFishman, avec quelques modifications importantes d’ordre culturel et régional. Le but principal de cette analyse était le<< analyse de domaine >> : il s’agissait de savoir que1le(s) langue(s) parmi le persan, le turc, le kurde et/ou l:31'l”1'lé111€I`létait dominante(s) dans les différents domaines sociaux. Les domaines sociaux ont été classés du plus infonnel ou plusformel ; ils comprennent la famille, la religion, les amitiés, le voisinage, les transactions, l’éducation et l‘administrationfl’emploi. Dans une société polyglossique, à chaque situation correspond une << haute >> (H) et une basse (L) << variété >>,et chaque variété a ses propres fonctions spécialisées. Le domaine d’analyse a été mis au point séparément pour chacunedes trois populations.Pour voir l’incidence des trois variables indépendantes choisies e l’âge, le niveau d’étude et le sexe — sur le choix de lalangue, le chercheur a appliqué différentes méthodes statistiques : le test-T et l’analyse de la variance à un facteur et àdeux facteurs (0ne-way cmd tw0—way ANOVA). Il apparaît alors que le sexe ne joue pas sur le choix de la langue maisque les deux autres facteurs connaissent quelques fluctuations dans toute la population.L’étude parvient alla conclusion que, dans la population turque, la langue de la région, le turc, est dominante dans tousles domaines sociaux. Chez les deux autres populations, à savoir les Kurdes et les Arméniens, la langue officielle, lepersan, est. dominante, avec néaimioins un usage plus fréquent dans les situations formelles. / The present study is aimed at analyzing the multilingual situation of Uimia from a domain analysis perspective. Threedifferent ethnic, Tinguistic, and religious minorities, namely Turks, Kurds, and Armenians are living in this city,speaking Turkish, Kurdish, and Armenian, respectively. The national language of the country, Lran, is Persian.Naturally, the people in this area are brought up bilingual or trilingual.To do the study, 900 questionnaires were collected from the whole city. 68l(328 Turks, 214 Kurds, and 139 Armenians)out of this were randomly selected. The questionnaires were basically adopted from Pishman's model with someimportant cultural and regional modifications. The main purpose of the study was domain analysis, i.e., to find outwhich language(s) from among Persian, Turkish, Kurdish and/or Armenian is dominant in different social domains. Thesocial domains which were hierarchically arranged from most informal to most formal ones include family, religion,friendship, neighborhood, transaction, education, and goveriunent/employment. ln each situation in a polyglossicsociety, there is a high (H) and a low (L) variety; and each variety has its own specialized functions. The domainanalysis was separately devised for each of the three different populations.To find out the effect of three independent variables of age, level of education, and sex on language choice, differentstatistical procedures of T-test, One-way ANOVA, and Two-way ANOVA were applied. While sex did not show tohave any effect on language choice, the other two factors had some fluctuations in the whole population.The study came to the_ conclusion that in Turkish population, the language of the region, Turkish, was dominant in allsocial domains. In the other two populations, namely Kurdish and Armenian, the official language, Persian, wasdominant while moving from more informa] to formal situations.

Agricultural Water Use in Lake Urmia Basin, Iran : An Approach to Adaptive Policies and Transition to Sustainable Irrigation Water UseFaramarzi, Nahal January 2012 (has links)
The Lake Urmia positioned in a closed basin in north-west Iran, positioned at altitude 1250 m above the sea level, and has been rapidly drying since 1990. The lake water level has declined to 1271.58 m in 2008 from the last highest record 1277.80 m in 1994. The lake water volume has fluctuated during the observation period and shows a drop from of 32 to 14.5 million cubic meters, while the lake salinity has increased from 205 to 338 g/l due to the evaporation and water inflow reduction. In the Lake Urmia basin, there has been an increase in public awareness of the possible environmental threat and the unpleasant socio-economical consequences on the region’s inhabitants. The main aim of this study is to assess the current water use pattern in the Urmia Lake basin system with emphasis on the agricultural sub-system, and to propose adaptive measures and sustainable water management scenarios. The study shows that the main cause for these changes are the diversion of rivers and streams for agricultural irrigation; agriculture is a sector with one of the highest water demands, and frequent drought in early 2000s exacerbated the situation. In addition, a growing population and the increased development of agricultural land has led to an increase in unsustainable practices which have an unpredictable impact on the Lake Urmia ecosystem. This study investigates sustainable water use strategies for Lake Urmia basin, and considers economic and environmental factors, including the loss of valuable ecosystems that highlights social and ethical issues for the current and coming generations.

Impact of irrigation development and climate change on the water level of Lake Urmia, IranBeygi, Heydar January 2015 (has links)
Lake Urmia, located in the north-west of Iran, is one of the largest hypersaline lakes in the world. In recent years, there has been a significant decrease in the lake’s area and volume by 88% and 80% respectively. An integrated water balance model of the Lake Urmia Drainage Basin (LUDB) and Lake Urmia was developed to identify these main drivers of the significant changes, and to investigate the possible future evolution of the lake under effects of projected climate change and land use change. We used an energy balance method to estimate the evaporation from the lake and the Turc-Langbein method to estimate the evapotranspiration from the drainage basin of the lake. Agricultural irrigation water was introduced to the model as an extra precipitation over the irrigated fields, after being subtracted from the surplus runoff (precipitation−evapotranspiration). The agricultural land development was assumed to be linear that changed from 300000 ha at 1979 to 500000 at 2010, which is consistent with the best available data on the actual irrigation development in the basin. We estimated the annual evaporation over the Lake Urmia and the evapotranspiration over its drainage basin as 932 mm and 287 mm respectively. Our results showed that decreased precipitation and increased temperature over the basin since 1995 could explain 68% of the observed lake level decrease. Irrigation developments during the last four decades were found to be responsible for 32% of the observed lake level decrease. Thus the future lake level of the Lake Urmia is very likely to continue to decrease unless the current climate condition will be followed by a period of increased precipitation. If the current climate conditions will prevail also in the future, even a 20% decrease in the irrigated land area, which is actually quite ambitious, will not make the lake recover to its ecological level at the end of 2020.
