Kampala city is a rapidly urbanized society whose growth is impacting on its wetland. Thus, this study examines the regulations, impacts and dynamics of urbanization in Bwaise wetland and how this affects the society since wetlands are source of livelihoods to some residents of Kampala. The study reveals that rapid urbanization and development have encouraged severe flooding of the wetland and its surrounding areas especially during the rainy season. The study advocate public education on importance of wetland utilization, management and importance to the society as a panacea in encouraging wetland restoration in Kampala V TABLE OF CONTENTS DECLARATION APPROVAL ii DEDICATION ACKNOWLEDGEMENT iv ABSTRACT v TABLE OF CONTENTS vi LIST OF TABLES ix CHAPTER ONE 1 INTRODUCTION 1 1.1 Background of the study 1 1.2 Problem statement 6 1.3 Objectives of the study 6 1.3.1 Main objective 6 1.3.2 Specific objectives 6 1 .4 Research questions 7 1.5 Scope of the study * 7 1.5.1 Geographical scope 7 1 .5.2 Content scope 7 1.5.3 Time scope 7 1 .6 Significance of the study 7 CHAPTER TWO 9 LITERATURE REVIEW 9 2.1.

Wetlands perform a number of ecosystem services, some of which are well recognized, others less so, and are internationally recognized as one of the most important ecosystems for the conservation of biodiversity (Carp, 1980). Wetlands also have important primary functions in the regulation of hydrology, water purification and flood control, and coastal wetlands can help to alleviate the impacts of storm surges (Kirsten, 2005). Further wetlands have aesthetic values and significant eco~tourism potential (Millennium Ecosystem Assessment, 2005). Wetlands are estimated to store more than twice the amount of carbon as all global forests biomass combined (Creswell, 2003). Drained and disturbed wetlands emit a massive amount of carbon dioxide and other greenhouse gases (Anonymous, 2008). According to the Millennium Ecosystem Assessment report, Wetlands are the habitat that has been most affected by development and are being lost more rapidly than any other habitat in the world. However, 80% of the global wetland area is still pristine and not severely modified by human activities. Globally, natural wetlands are destroyed at a rate of 4000 square kilometers per year, with 50% attributed to agriculture, 30% to forestry and 10% to peat extraction (Creswell, 2003). In Uganda, Wetlands are one of the most valuable ecosystems and cover about 30, 105 square kilometers, representing 13% of the country’s total area (National Environment Management Authority, 2000). The national environment act of Uganda defines wetlands as “areas which are permanently or seasonally flooded by water and where plants and animals have become adapted”. There are two broad categories of wetlands in Uganda, namely, those which are associated with lakes (Lacustrine) and rivers (Riverine) (National Environment Act, 1995). This has resulted into degradation and modification of these valuable stocks of natural capital. This 1 situation arises out of the fact that wetlands are perceived to have little or no economic value (Kirsten, 2005), coupled with the fact that no formal markets exist for their services to humanity (Jodi, 2005), consequently, this makes wetland conservation not to be seen as a serious alternative compared to other uses that seem to yield more tangible and immediate economic benefits. As a result inadequate resources are fed into their management which breeds environmental degradation through inappropriate commercial use of wetlands (Oglethorpe and Miliadou, 2000), which consequently affect human welfare. Despite the important ecosystems services wetlands deliver, Ugandan wetlands have been greatly altered by human activities. The Government of Uganda made significant progress in establishing a comprehensive policy, legal and institutional framework for wetlands management (NEMA, 2000). Nonetheless, there are implications of rapid urbanization in Uganda that undermine the sustainable utilization and management of wetlands in Uganda (NEMA, 2002). Kampala is the capital and largest city of Uganda. The city is divided into five boroughs that oversee local planning, that is to say, Kampala Central Division, Kawempe Division, Makindye Division, Nakawa Division and Rubaga Division. Kampala’s population is approximately 1,507,080 and the density is 7,928/km2 (ROU, 2017). Wetlands in Kampala have continued to experience serious degradation for example Bwaise wetland in Kawempe division, which continues to threaten the quality of water. Though there are various interventions by the government and its organs to encounter the problem of water quality for public use through waste water treatment plants and water treatment plants, still there is a forgotten treasure of hydrological functions of natural wetlands in Kampala, due to the rapid implications of urbanization in the area, for example urbanization has encouraged human settlements in wetlands, over exploitation of wetland resources such as clay, and others. Urbanization refers to the population shift from rural to urban areas, (Wikipedia, 2018) “the gradual increase in the proportion of people living in urban areas”, and the ways in which each society adapts to change (Wikipedia, 2018). It is predominantly the process by which towns and cities are formed and become larger as more people begin living and working central areas (. The United Nations projected that half of the world’s population would live in urban areas at the end of 2008 (UN News, 2008).
