Through a case study on the Zijun Samatao community of Kunming City in Yunnan Province of China, this paper discusses the impact of urbanization and mass Han Chinese migration on the endangerment of an ethnic minority language and culture. Samatao of Kunming is a subgroup of the minority Yi nationality of China. Historically, Kunming was the original homeland of many Yi communities including the Samatao. With the fast pace of urbanization and increasing Han Chinese migration, the Samatao community is losing their language and has lost their traditional culture and religion. Urbanization has brought mass migration into Zijun village, accelerating the endangerment of the Samatao language. Of nearly three thousand registered Samatao people, fewer than 100 (including semi-speakers) have any level of active knowledge of their language and culture. Since 1994, the endangerment of Samatao language has dramatically increased, especially since 2003. Based on data from fieldwork in the community over more than twenty years, this paper explores how the ideals of the Samatao community about preserving their language and culture are challenged by the contextual reality of urbanization and mass Han Chinese migration.

This paper is concerned with the impact of urbanization in aquifer well-system located in the Municipalarea of Arusha city, Tanzania. A system dynamic (SD) model was built under VENSIM PLE workbench fromtwenty-five years (1978-2003) physical and non-physical data to simulate their interactions and relations.This involved use of mathematics ideas and concepts in studying the physical and non – physical componentsseparately, and finally putting them together in new form (model) and study their relations. After model wasfound to be structurally complete and simulate properly by using the model and unit check tool of VENSIMPLE,parametric calibration of the model follows. Model output results were then compared with existing fieldconditions and information’s with the help of Excel spreadsheet. Historical data of population, rainfall, GDP,aquifer characteristics and land use was used as inputs. The model was trained for data series of 1978 to 1990and examined for data series of 1990 to 2003. Model efficiency criteria R2, suggested by Nash and Sutcliffe(1970), produced good results ranging from 0.6333 to 0.9868 during calibration and 0.9833 to 0.9985 duringverification. The model reveals that urbanization has enormous impact on population which was increasing ata rate of 4% from 1978 to 2003, which in turn caused increase in water demand for about 6% annually; as aresult aquifer well-system was overstressed due to over-pumping. Lastly a prediction of the situation for 2025was carried out in succession, and then interpretations and discussion concludes the paper.

Urbanization is a major factor that shapes the pattern of urban area of cities and exerts influence on cities’ development. The pattern of urban expansion and sprawl is considered as the main feature for evaluating the development of a city, which can dramatically reflect the path of urbanization and largely influence the potential of sustainability of a city. The objectives of this study were to introduce a sustainable development indicator - compact coefficient of urban area (CCUA), specially designed for evaluating the sustainability of a city in spatial dimension, and reveal the impact of urbanization on the sustainability of a city through comparing the trend of urbanization rate of a city with its changes of CCUA. A case study has been taken in Yantai, a medium-sized city in east part of China. Remote sensing was used for mapping the land use/land cover changes of urban area in Yantai from 1990 to 2010 by using the medium-resolution satellite imagery. Then, five indexes of ecological landscape were selected and processed, and CCUA of Yantai was calculated. Results of this study indicate that CCUA is an efficient indicator for measuring the sustainability of the pattern of urban expansion, which can assist the urban planning process of professionals and facilitate the decision-making process of local government.
