Determining the solar energy potential on a surface depends on geographical location, prevailing meteorological conditions, size, shape and orientation of a surface. In urban areas shading is an important parameter, given the density of buildings and must be considered in an evaluation of available irradiation. This thesis develops an integrated workflow for modelling and mapping solar energy potentials in urban areas. This was accomplished through a case study of a typical large urban centre - The City of Toronto, using 3-D building models and selected software tools. The developed workflow was applied and successfully modelled the solar energy potential of buildings in the selected case study area. The results allowed for further characterization of the main factors affecting solar energy potentials on building surfaces in urban areas. This preliminary study indicates that, in comparison to HVAC systems and green roofs, shading may be a less important factor to consider when estimating solar energy potentials in some urban settings.

This paper presents a method for estimating the solar capture capacity of dwellings using the central urban area of Concepción, Chile, as a case study in order to promote self-generation of energy by residents. The method takes into account the growing domestic energy demand and the possibility of meeting this demand through integrated solar energy collection into buildings using different systems. The methodology considers a study of the potential incoming solar radiation on buildings according to their geographical location and the surrounding buildings. The capacity for solar capture is then estimated for different dwelling types according to their morphology. Subsequently, the energy contribution provided by different technologies (solar thermal, photovoltaic and hybrid) is identified in relation to the main average energy demands for electricity, water and space heating. Finally, systems for each dwelling are recommended in an urban map available online. The development is based on climate information, cartography, aerial photographs, surveys, housing models, technical standards, standardised calculations and dynamic simulations, implemented according to building layouts from an online Geographic Information System (GIS). The housing types are categorised in an urban map that relates household demands and the contribution of different solar energy systems. According to the estimates calculated, the residential units in the study offer sufficient solar capacity to supply between 40 and 60% of their energy consumption, especially in detached houses using roof-mounted hybrid systems.

Literacy Level

This research examines the factors affecting the financial literacy of Vietnamese adults. Using a sample of 266 observations of adults in 2 big cities in Vietnam (Hanoi and Vinh in Nghe An Province), the author evaluates the literacy level of adults in these urban areas. The financial literacy of the interviewed people is low. The multiple regression results show that lower financial literacy levels associate with higher age and married status and higher financial literacy levels associate with higher education, more family members, the person making financial decisions and the person attending a useful financial course. This research also explores the association between financial literacy and financial behaviors of individuals employing logistic models. It is found that higher financial literacy associates with less probability of overspending and higher probability of saving money and careful spending. Higher financial literacy is also found to associate with higher probability of opening a savings account and making various investments.

In this study, the solar energy potential of Turkey was investigated. Among the alternative clean energy resources in Turkey, the most important one is solar energy. Turkey's solar energy potential has been estimated to be 26.4 million toe as thermal and 8.8 million toe as electricity. Generally, solar energy is used for heating and the consumption of solar energy has increased from 5 ktoe in 1986 to 335 ktoe in 2003. Turkey's geographical location is highly favourable for utilization of solar energy. The yearly average solar radiation is 3.6 kWh/(m2 day) and the total yearly insulation period is approximately 2460 hours, which is sufficient to provide adequate energy for solar thermal applications.

Market Gardening

<p>This research investigates the role market gardening plays in the livelihood strategies of rural-urban migrants. It contributes to the literature on market gardening, livelihood strategies and migration by positioning market gardening as a highly flexible and adaptable mechanism for managing the rural-urban transition among households with few labour alternatives. Such perspective elevates market gardening from simply being a land use category to being an active instrument in the management of rural-urban migration processes.  The expanding urban centre of Kapit, Sarawak, Malaysia is used as a case study of a rapidly expanding small town in a predominantly rural domain. Market gardening emerges as an important source of income for both individuals and households as rural-urban migrants negotiate the transition between farming and urban settlement. Many rural-urban migrants adopt market gardening or associated market selling as their first employment in urban centres. First generation migrants often have low off-farm skills which limit their ability to take on alternative occupations.  While a rise in market gardening activity is enabled by a growth in demand for fresh vegetables, in the context of Sarawak it is also heavily influenced by the involvement of the state that actively encourages participation, provides advice to farmers and offers subsidies. The expansion of roads from rural to urban areas also plays an important role in improving market gardeners access to urban markets, as well as their access to material inputs. At the same time, increased access has heightened competition by attracting new entrants to urban vegetable markets.  Interviews with 10 sellers and 30 market gardeners from Kapit were conducted in 2004. In contrast to market gardening in larger centres documented in the literature, this small isolated town case identifies market gardeners as typically middle-aged, rural-urban migrant women with limited education and employment skills other than subsistence farming. Market gardening and associated selling is adopted because they are unable to acquire alternative employment to support their household and children’s education. As such, market gardening in the urban setting is a logical extension of the woman’s role as the primary farmer in rural areas.</p>
