Abstract

The urban areas in Uganda are increasingly getting under pressure from a rapidly growing population. The challenge of a growing population has coincided with the central government policies that favour rural districts more than urban areas.The challenges that the urban areas face include the problem of two populations (the night and day time); high generation of garbage; poor revenue base; a growing informal sector; growing squatter settlements; deterioratingwater quality; and the limited institutional capacity to provide the required urban services. Financial resource mobilisation has been inadequate due to high costs oft= administration, low institutional capacity for enforcement, and a general public apathy to tax payment.

Abstract

The research was conducted in Yogyakarta Special Province. The main objective of this research is to find out the main factors influencing the change in agricultural land use especially rice field. The data used in this research is time series from 1980 to 2000. They were obtainedfrom several institutions such as: Central Bureau of Statistics (BPS), National Agency of Land Affairs (BPN) and Department ofAgriculture (Dinas Pertanian). Descriptive analysis and statistical test were performed against those data to find out the influence of geographic factors i.e. the population growth, the road development and the extension of built up area on the change in agricultural land use especially rice field. Distributed lag model is used to analyze the effect of road's length on agricultural land use change. The level and magnitude of relationship between areas of agricultural land use change and built up area, number of people and road length are calculated using linear regression.The research shows that the period of 1980 - 2000 in Yogyakarta Special Province has indicated very significantly the increase in population, the development of road and the extension of built up area. For the time being, agricultural land mainly in Sleman Regency, Bantul Regency and Yogyakarta Municipality has decreased. Sleman regency performed the largest decrease of rice field and followed after then by Bantul regency and Yogyakarta Municipality. The regency of Kulon Progo and Gunung Kidul have experienced reverse phenomenon i.e. the increase of rice field during this period. Individually or simultaneously, three variables used in this research (number of people, road's length and built up area) have significantly influenced the agricultural land use.

Abstract

This papaer assesses development of coastal sand dunes particulary along tropical coast. in depth study along on coastal dune morphology along Medinipur coastal track shows that sea levels remained very dynamic during the Holocene period. Evidence of Holocene sea level changes are found which were responsible for for the origin almost parallel distinct dune colonies through the geological past along this coastal track. The existence of tropical-monsoon climate with its seasonal phenomena plays an important the barrier property of dunes as well. in this paper possible biologcal interactions between sand mass of dunes and vegetation in different stages of development has also been dealt.

Abstract

This study was conducted in Pogung-Code sub watershed and Pulo-Opak sub watershed from 1993 to 2002. A deterministic model developed by Haan (1972) was used to determine the amount of water yield from watersheds. The model consists offour parameters, namely: (0 maximum rate of seepage from the soil water zone in mm per day (S), (ii) maximum soil moisture less readily available for evapotranspiration in mm (C), (iii)fraction ofseepage from the soil water zone that becomes runoff(F), and (iv) maximum infiltration rate in mm per hour (f.).The inputs required by the model were the daily rainfall and the estimated potential evapotranspiration which was computed using Penman method. Streamflow records for 10 years of Pogung-Code sub watershed (2,801.77 ha) and Pulo-Opak sub watershed (4,856.37 ha) were used to test the validity of the model. The parameters obtained for Pogung-Code sub watershed were: S = 0.70 mm per day, C = 112.32 mm, F = 0.63, and- 5.38 mm per hour, meanwhile for Pulo-Opak sub watershed were: S = 2.33 mm per day, C = 86.72 mm, F --- 0.26 and f = 5.68 mm per hour.The final test of the adequacy of the model lay in a comparison of observed and simulated runoff The comparison showed that the observed and simulated runoff values are not significantly different. This was based on the results obtained from statistical measures to test the model. The model did a better simulation in the smaller watershed (Pogung-Code sub watershed) than in the larger one (Pulo-Opak sub watershed).
