This thesis aims at analyzing the impact of water on economic growth and economic development. We explore different topics that are directly linked to the availability of water, which directly influence economic growth and development. The thesis consists of four studies. The first study models the effect of water utilization and water pollution on economic growth. The second study is based upon reflections on the fixed effects model and makes the distinction between the impact of the mean of a variable X and deviations from that mean on another variable Y. To date it has tended to be assumed that these impacts are the same; we argue that this is not always the case that countries can to an extent adjust to a specific water environment. However having adjusted they face problems when the water environment deviates from the mean. In the third study we explore the effect of different socio economic factors such as labour productivity, agricultural inputs, population density, water resources per land, and variables such as the trade regime, on water withdrawal for the agricultural and non-agricultural sectors. A specific focus is on the interactions between these two sectors. This study is new in its content and its theme of the work. We argue that many global trends will put increasing pressures on agricultural and non-agricultural water use. But there is also potential for increased efficiency in this use. The fourth study tries to fill the gap in the literature that deals with development aid for water and sanitation. We explore the impact of aid and aid volatility on safe access to water and sanitation, using a newly available OECD/DAC data base. Specifically, we analyse both the recipient countries and the donors to determine the role of aid in affecting safe access to water and sanitation.

This research aimed to assess the potential of social entrepreneurship to contribute in increasing the economic participation of the youth in South Africa. With South Africa experiencing high levels of youth unemployment and characterised by a population “youth bulge”, an economically excluded youth impedes the economic development plans of the country. Therefore all economic sectors in South Africa should be assessed for the potential to increase the economic participation of the youth to aid the delivery of the economic development goals. The research was conducted using a qualitative research methodology as the nature of the research problem lent itself to more descriptive and rich answers. The field of social entrepreneurship is also relatively new and the data available for quantitative analysis is limited.The research found that social entrepreneurship has a potential to increase the economic participation of the youth but is failing to deliver results mainly as a result of legislation not recognising a legal entity for social entrepreneurial activities. The disparities in the definitions of key social entrepreneurship terms, lack of awareness about the sector and the challenges surrounding the sustainability of social enterprises do not render social entrepreneurship as an economic opportunity of choice for the youth. / Dissertation (MBA)--University of Pretoria, 2014. / zkgibs2015 / Gordon Institute of Business Science (GIBS) / Unrestricted
