Abstract

This study is an attempt to investigate the general level of fertility in Kafanchan, a town in Kaduna State of Nigeria: The main concern is to examine the individual and group behaviour of the population with specific reference to the prevailing fertility rates.The paper examines some of socio-cultural factors that relate to fertility history, attitude related to fertility and knowledge and use of contraception.On the average, fertility in this community is high. A woman experiences a total life time fertility of 7 live-births and least one of the children die in childhood. Marriage is universal and every young man and woman aspires to satisfy this social obligation. The mean age at marriage is 17 years. A lot of importance is attached to having children, for social and cultural reasons. Knowledge and use of contraception is still very low. Government interest in population matters has been mainly restricted to population data collection for the purpose of soda- economic and political planning. These factors have a positive bearing on average family size which is relatively large.Fertility is high while mortality is low. However, as a measure towards demographic readjustment, a further reduction in the level of mortality may lead to decline in fertility. Some future planning implications of the existing fertility' evels are discussed in the light of the current population policy and development planning in the country.

Abstract

The aim of the research is to know a soil sequence based on the physiographic unit along volcanic slope and limestone area, i.e. south slope of Merapi volcano from Kaliurang to Baron coast, Yogyakarta, Central Java.This research is based an topographic differences as a lithological reflection. Seven sample points are determined in order to discribe and evaluate morphological types of soil profile, physical and chemical properties, and environmental factors. Relative soil potential is analyzed on the basis of the field data. From this research the soil types found in the study area are Regosol, Cambisol, Latosol, Rensina, Grumusol, and Mediterannean.

Abstract

The Barmah River Red Gum forest are part of a larger tract of such forests along the River Murray. It is known that river flooding provides an important source of water for the sustenance of these forests. The contribution of River Murray tributaries to the flooding of these forest was examined. The main stem of the River Murray above lake Hume was the single most important source. Removal of this would lead to a 55 percent decrease in forest flooding. Removal of either the Ovens or the Mitta Mitta would lead to a 30 percent reduction in flooding, while removal of the Kiewa river would lead to a 15 percent reduction in flooding. No particular tributary can be regarded as a source of extreme forest floods since all tributaries more or less act in concert. A backwater influence of high water levels at the down strewn confluence of the Goulburn and Murray Rivers leads to high water levels in the River at Barmah. However, because of the short-lived nature of such high, water levels it is unlikely that such floods penetrate very far into the forest unless they are also associated with flows in the River Murray.

Abstract

Reports of lansdlide and sinking stc., at Tawanghat and its surrounding areas have been reported in past also with noticeable amount of loss of lives properties.A Sizable landslide accured in this region in december, 1962.During august 1977, a major landslide came roaring down the main nala (a local term used for small channels or stream) of Khela village and destroyed sheds and houses, killing 44 persons and 76 heads of cattle.About 150 acres of standing crops were washed out.Geological and geomorphological investigataion showed that a large area was dislocated at the head of the nala moving down the gradient and activating the boulder filled nala.The mass of the mountain scree that moved was perhaps resting already at a critical angle and the torrential rains had triggered the flow.In August, 1979 again a major gravitational slide of the steep mountainslopes between Rauntigad and tawaghat region had accured, seriously affecting Sinsa, gachila and Syankuri village situated on the above slipes.
