Water samples were collected from taps, wells and in sachets (table water) from various locations in Abeokuta South Local Government Area. The samples were subjected to physicochemical analyses in order to determine the suitability of the waters for drinking purposes. pH, temperature and conductivity were determined using Hana Combo (HI 98129). Evaporation method was used for total solids determination while titration was employed for alkalinity. Trace metals were subjected to Atomic Absorption Spectrometry (AAS) while Multiple Tubed Fermentation Technique was used for the microbial examination of the water samples obtained. From the results obtained, Fe (mg L-1) values obtained ranged from 0.25-0.61 for tap water, 0.01-0.635 for well water and 0.09-0.35 for sachet water. Cu values obtained were lower than the WHO limit of 2.00 mg L-1. All lead values for tap and well water were higher than the WHO 2008 standard of 0.001mg L-1. Coliform was detected in well water samples from Elega, Adatan, Ake, Sapon, Ikereku and Kuto. Water samples for tap and sachet waters were free from coliform bacteria. From the results obtained, Sachet water is most suitable for drinking since coliform bacteria were not detected and the values obtained from the physicochemical analyses were lower than the WHO standards. Tap water should be well treated before distribution for public supply while well water should not be used for drinking purposes.

Assesses the potential of the intensive afforestation program in Nigeria. Reduction in the atmospheric concentration of carbon; Employment of the mitigation analysis process model in the study; Decline in the importation of wood products.

This paper attempts some preliminary evaluation of the potential of agroforestry techniques as a forestry strategy for controlling atmospheric CO[sub 2]—a critical greenhouse gas. The end-use scenario that attempts to meet the wood and related needs of the nation while mitigating climate change was adopted. The net emission estimate for the Forestry Sector in 1990—the base year for the study—was 9.5 million tonnes of carbon (MtC). Based on this figure, projections into the year 2030 gave cumulative net emissions of 427.4 and 580.5 MtC at 1.3% and 2.6% deforestation rates respectively. However, mitigating with agroforestry techniques, assuming that about 76% of the estimated 39.5 million ha of farmland in the country is committed to a variety of agroforestry systems, the results show that a total of 1530 MtC can be withdrawn from the atmosphere by the year 2030. The paper concludes that there is a reasonable case for the use of agroforestry techniques in the country, both as a means of sustaining soil productivity and as a strategy for mitigating climate change.
