The quality of Amba River in Nasarawa State in the North Central Nigeria was investigated for a period of one year covering dry and rainy season. Water samples were collected from four different locations (Gandu, Wadatan-Waje, Kofan-Kaura and Unguwan-Galadima) along the river course and analyzed for Bacteriological parameter, using standard methods. The results indicated seasonal variation in coliform population with higher values at Wadatan-waje and Unguwan-galadima during rainy season. The values obtained for coliform on the average for the two seasons were beyond the maximum acceptable standard set by the World Health Organization (WHO, 2004) for drinking water. Thus, settlers along the River should be enlightened on the danger of consuming untreated water from the River. Also, measures at regulating the pollution of the River should be taken for a healthy and vibrant community.

The amount of rainfall received over an area is an important factor in assessing availability of water to meet various demands for agriculture, industry, irrigation, generation of hydroelectricity and other human activities. Over the study period of recent 30 years, trend values of monsoon average rainfall in Chittagong have increased. This paper has measured the correlation coefficients between rainfall and time for Chittagong, where correlation coefficient for Chittagong is positive. In order to check the strength of linear relationship between rainfall and time, P-value has been measured. Due to various factors of Chittagong region of Bangladesh, there is a growing need to study the rainfall, temperature and humidity pattern. This study was checked annual average rainfall of 30 years, temperature of 60 years and humidity of 28 years for this region. It is hoped that this research may be of help to the concerned organizations and experts working on increasing climate variation in Chittagong.

This paper presents the findings of the socio-economic impact of household-level water harvesting technology. Before water harvesting was introduced, onions were not grown in the area due to lack of seedlings. Thus onion seedlings were grown on 100 m2 plots using water from the ponds in the dry season, then sold or planted under rainfed conditions during the rainy season. The results obtained show that the average net income from onion seedlings was 155 US$ per 100 m2 plot, while those from bulb onions grown rainfed in the field was 1848 US$ per ha, making the contribution to farmer incomes by onions alone about 2003 US$ per year which is higher than from rainfed teff and wheat combined.
