Discovering the quality of the environment is essential because it directly affects health status and plays a significant role in the quality of life and public health. This research aimed to evaluate the environmental quality affecting by human-made sources in Duhok province using GIS. Based on the human-made sources affecting the quality of the environment, including population density, solid waste generation, and industrial density, the state of the environment was evaluated in the study area. The overall result indicated that about 85% of the study area has a moderate to high-quality state, while low and very low contributed to 13% and 1%, respectively. The integrated analysis of the environmental quality in Duhok province would increase the protection of the ecological environment and help the regional sustainable development and improvement of the built environment.
The problem of portable water supply has become an issue of global concerned as governments all over the world are trying to make house-holds water accessible to all as easier as possible to meet the challenges for sustainable development goals. This research has been conducted to determine the people’s perception on domestic water supply situation in Kano metropolis, Northwestern Nigeria. A self-designed questionnaire developed and distributed to the subjects using stratified sampling technique, and the data obtained has been presented in frequency and percentage. The results obtained revealed that, there is a scarcity of portable water supply to households in Kano metropolis. The problem emanated from lack of pipe-borne water which necessitated the dependence of the house-holds water supply on vendors that obtained water from boreholes and some hand-dug wells lacking proper hygienic practices. More so, the respondents were willing to pay for pipe borne water delivery, yet, they depend on vendors as their major water suppliers as alternatives. The unhygienic practices of the vendors and water sources posed threat to public health concerned.
