Mass wasting, one of the major natural disaster, have resulted into significant injury and loss to the human life and damaged Property and infrastructure throughout the world. The studied area is located in the Alborz mountains Range from Karaj to Chalus, central Alborz mountain range, Iran; where is frequently affected by several different mass wasting types and needs to be considered and immediate attention. In this study 9 causative factors, include: drainage density, aspect, slope, vegetation density, lineation density, main fault buffer, landuse, lithology and seismic activity was considered. The studies have shown that the northern part of the rout falls under very low to low risk except near the MarzanAbad city because of the KalarDasht heights. Increasing vegetation density is one of the reasons for reducing the risk in the northern part of the rout. Very high risk zones are mainly concentrated between Aderan and Nesa cities that explained by the presence of steep slopes and the effect of the faults which affected this section of rout. There are significant risk reducing by getting away from the road. In general, most of the areas on this rout are zones that have the medium to high instability.
This study uses new estimation methodology in landslide hazard zonation in Karaj-Chalus Road and the results of this study will help to preventing slope instability by enhancing the high risk areas.

Begging has seen more critical social issue in most urban centers of developing states. The present study explores the relationship between begging and land use in District Lahore_Pakistan. This study is based both primary as well as secondary data. To determine the spatial variations of begging, well-developed questionnaires were designed to get relevant information from randomly selected beggars. The study which used z-score to compare the concentration of begging in the study area verified that the occurrence of begging is a function of land use activities. It recommends that more research works should be done on the problem of begging to observe more relationships between begging, land uses and other social issues such as urbanization, socio-economic background, poverty and culture.
This study used a new technique of GIS hot spot analysis through which different hot spots and cold spots of beggars were explored. This study is one of very few studies which have investigated and verified a relationship between begging and different land use.
