In order to effectively evaluate the urban water security, the study investigates a novel system to assess factors that impact urban water security and builds an urban water poverty evaluation index system. Based on the contribution rates of Resource, Access, Capacity, Use, and Environment, the study adopts the Water Poverty Index (WPI) model to evaluate the water poverty levels of 14 cities in Gansu during 2011-2018 and uses the least variance method to evaluate water poverty space drive types. The case study results show that the water poverty space drive types of 14 cites fall into four categories. The first category is the dual factor dominant type driven by environment and resources, which includes Lanzhou, Qingyang, Jiuquan, and Jiayuguan. The second category is the three-factor dominant type driven by Access, Use, and Capability, which includes Longnan, Linxia, and Gannan. The third category is the four-factor dominant type driven by Resource, Access, Capability, and Environment, which includes Jinchang, Pingliang, Wuwei, Baiyin, and Zhangye. The fourth category is the five-factor dominant type, which includes Tianshui and Dingxi. The driven types impacting the urban water security factors reflected by the WPI and its model are clear and accurate. The divisions of the urban water security level supply a reliable theoretical and numerical basis for an urban water security early warning mechanism.

Purpose: This study aims to map the spatial distribution of poverty using nighttime light satellite images as a proxy indicator of economic activities and infrastructure distribution in D.I Yogyakarta, Indonesia. Research design, data, and methodology: This study uses official poverty statistics (National Socio-economic Survey (SUSENAS) and Poverty Database 2015) to compare satellite imagery's ability to identify poor urban areas in D.I Yogyakarta. National Socioeconomic Survey (SUSENAS), as poverty statistics at the macro level, uses expenditure to determine the poor in a region. Poverty Database 2015 (BDT 2015), as poverty statistics at the micro-level, uses asset ownership to determine the poor population in an area. Pearson correlation is used to identify the correlation among variables and construct a Support Vector Regression (SVR) model to estimate the poverty level at a granular level of 1 km x 1 km. Results: It is found that macro poverty level and moderate annual nighttime light intensity have a Pearson correlation of 74 percent. It is more significant than micro poverty, with the Pearson correlation being 49 percent in 2015. The SVR prediction model can achieve the root mean squared error (RMSE) of up to 8.48 percent on SUSENAS 2020 poverty data.Conclusion: Nighttime light satellite imagery data has potential benefits as alternative data to support regional poverty mapping, especially in urban areas. Using satellite imagery data is better at predicting regional poverty based on expenditure than asset ownership at the micro-level. Light intensity at night can better describe the use of electricity consumption for economic activities at night, which is captured in spending on electricity financing compared to asset ownership.

China is in the process of carrying out socialist planned economic system and capitalist market economic system along with its reforms and opening. In the process, the problem of poverty is surfacing along with the commercialization of housing. In this study, we've analyzed China's social security system through literature at home and abroad based on the concept of place poverty, and have pointed out the characteristics and problems of Chinese urban housing reform centered around what we've identified. Furthermore, we've divided up China into 8 zones, and have examine the characteristic of each area by population & social index, economic index, and housing index. As a result of analysis, the process of urban housing reform had an effect on housing poverty, and appeared to have different characteristics by zone. In this study, since China's situation by area is very diverse, it presents a point that we must approach with not a monistic method but a pluralistic method regarding housing policy.

This study decomposes the gender differences on poverty to explain the causes of the poverty gap between male- and female-headed households. In order to do this, we start from examining the extent of the poverty gap between maleand female-headed families and then conduct decomposition of poverty differences by gender using the Oaxaca method. This paper uses the (Urban) Family Budget Survey data from 1982 to 2008 and measures poverty using 50% of the median income poverty line. Major findings of this study are as follows: First, in 2008, the coefficient effect explains 70% or more of the total gender-poverty gap. Second, the trend of gender-poverty gap in the period of 1982~2008 shows that the poverty gap by gender increased in the 1980s', decreased in the 1990s', and a re-increased in 2000s'. Third, comparing the decomposition results in 1982, 1989, 1999, 2008, we found that the share of characteristic effect of the total gender poverty gap has been increased gradually over time. It means the characteristics of the female-headed households have become worse than those of the male-headed households in urban working families. At the same time, the still large coefficient effect suggests that the problems such as the discrimination against matriarchs or the lack of social support for them still play important roles among urban working families in Korea.

In recent years, it seems that a considerable stratum of working poor as a new urban poverty among labor population within large cities has been generated, deepening socio-spatial conflicts. This paper is to bring focus on the working poor which can be seen as a newly emerged special problem intermingling labor and poverty. It first begins with a consideration of definitions on the working poor, then discusses on the internal relationship between labor and poverty problems by analyzing causes of the generation of the working poor and looking into actual conditions of working poor from both static and dynamic perspectives, and finally considers existing policies for supporting the working poor, suggesting some alternative policy tasks for resolving the problem of the working poor.

The major purpose of this study was to offer a comprehensive analysis of the changing trends and causes of poverty among urban wage earners' households from 1995 to 2005. In order to do that, this study used the micro data of "Income and Expenditure Survey of Urban Households" by the National Statistical Office(NSO) and GEE(Generalized estimating equation) regression model which is know as an appropriate method for the longitudinal and clustering data. The results show that (1) the numbers of poverty rate and poverty gap in recent years are even getting seriously worse than those in the IMF crisis. (2) Main characteristics of poor are female headed, old aged, low educated households, and having atypical working position. (3) Major determinants of poverty are also related to the variables as mentioned the above. (4) However, poverty reduction effect of public transfer increased preferably in recent years.

This study is an empirical research to analyze how many private income transfers in Korea decrease poverty rate, to compare the effects of private income transfers' decreasing poverty rate with income classes. This study has utilised the Family Income and Expenditure Survey to estimate the poverty ratio in urban areas and Unemployment Household Survey which Korea Institute for Health and Social Affairs has investigated at 1998. Majour findins are these. First, Sizes of private transfers incomes are much than that of public transfers incomes. The rates in receiving private transfers income are ten times higher than that in receiving public transfers income among urban worker's household. The mean of private transfer income are about six times larger than that of public transfer income among urban worker's household. Second, the effects of private income transfers' reducing poverty rates are not large. After private transfers, urbarn workers' households are about 10 per cent away from its poverty line, and unemploy households are only 3 per cent away from its poverty line. Third, especially, private income transfers are hardly reducing poverty rates among extreme poverty class. After private transfers, urban workers' households which their incomes are within low 5%, are not away from its poverty line at all.

The purpose of this study is to investigate the empirical relation between economic growth and poverty in Korea. Especially, the focus is put on exploring if there are any changes in the relation of economic growth and poverty. From 1982-2004 Korea Urban Household Survey, I constructed the annual data of poverty rate. I also obtained the annual data of the real GDP and the unemployment rate from the National Statistical Office. Using these annal data of the poverty rate and the macroeconomic performance, I analyzed the relation of them. As the result, I found that the macroeconomic growth have played very important role in reducing the poverty rate in Korea. Since 2000, the macroeconomic growth have still worked as an effective instrument for poverty reduction. However, there have been poverty increase that has not been explained by the macroeconomic growth since 2000. Based on these results, this paper suggests that the anti-poverty strategy in Korea should be changed from the old strategy emphasizing only economic growth to the new strategy pursuing both economic growth and social security simultaneously.
