The research aimed at determining the risk of fire hazard of the settlements in the area of Khalishpur, Khulna which is close to three oil depots and two power stations. The maintainence of land use zonal variance is completely absent in this area. The research has followed four stages. First, ptrliminary study was done for choosing the most vulnerable samples, then the factors for identifying the risk index are considered on the basis of hazard, vulnerability and exposure. After collecting the required primary and secondary data, the Analytical Hierarchy Process (AHP) method is used to identify the weightage of each of those sub-factors.Then the risk equation is used to identify the risk level of each buildings and a map is prepared by using their coordinates and risk level. The study states that, 55% of the total samples are in the medium risk profile. Journal of Engineering Science 12(2), 2021, 109-118

Community garden (CG) is a form of urban green space. It provides social, economic, health and environmental benefits to the urban people in a city. Bangladesh's third largest city is Khulna, which is dominated by agriculture, two of the Wards of this city namely Ward no. 17 and Ward no. 20 are selected as the study area for this study. In many established and developing countries, community gardening is a common feature of urban development, but it is a new concept in Bangladesh. The study aims at exploring the potentials i.e., factors or favorable reasons of introducing community gardens in Khulna City. A wide range of related literature on community gardens are reviewed. A total of 300 households of the study Wards are surveyed through semi-structured questionnaire, key informant interviews of urban planners, civil engineers, architects, agriculturist, environmentalist and sociologist are conducted with review of Khulna City master plans, and other reports and publications. The study finds that approximately 3. 67 acres and 2.43 acres land in Ward no. 17 and Ward no. 20 remain vacant respectively. Also, after knowing the pros and cons of CG, 58.33% people in Ward no. 17 and 60% people of Ward no. 20 become interested to participate in CG. If it is possible to utilize the vacant land for community gardening, community gardens on one acre land having 17 decimal or 10.30 katha land of each community garden will be capable to sequestrate about 3.5 tons of carbon per year and depending on the size and duration of rain event, will be able to hold about 2000-10000 cubic ft. of storm water per year. The study also proposes some sites for the development of community gardens in future.
