Published Article / This study focuses on trials conducted on plots in the Leratong and Mpho vegetable gardens in the Eastern Free State. The aim was to investigate the possible impact of soil compaction on the growth of carrots planted on loosened (treated) and unloosened (untreated) soil. Aspects such as sprouting, vegetative length after 14 days of sprouting and diameter, as well as the length and mass of carrots after harvesting, were observed and compared between the treated and untreated carrot plots. Although there was no significant (P>0.05) difference between the two soil management practices applied in all locations, as well as the vegetative growth in the locations, a significant (P<0.05) difference between the length of carrots from the treated and the untreated plots was observed.

Sustainable Built Environments Senior Capstone Project / School gardens are booming in Arizona as their opportunities for educational development continue to grow. One common problem, however, is that most schools with a school garden lack a proper managerial system that would help their garden be used to its full potential. The work compiled in this capstone project defines a managerial structure and provides a site-specific example of an intern manual that is intended to be used as in introductory guide with all the necessary resources to get an intern started.

The purpose of the report was to do an inventory of nursery gardens in the surroundings of Umeå and to find which one of the nursery gardens that had the greatest risk of being polluted by pesticides and to examine which pesticides that had been used in the nursery gardens in the past. Five nursery gardens were selected and examined through interviews, visits and protocols from the municipality of Umeå and from that information an assessment by the methods for inventory of polluted soil (MIFO), which the Swedish form of EPA has designed, has been done. The historical use of pesticides on each site was examined through interviews, visits and protocols from municipality of Umeå. The result showed that two of the nursery gardens had a great risk of being polluted and the total historical use of pesticides resulted in total 107 different products. In conclusion the two of the nursery gardens that had a great risk of being polluted will eventually have to take sample of the soil for further analysis.

This thesis interprets and maps some key stratigraphic and structural elements of Garden Bank (GB) Block 191 applying both geological and geophysical techniques. The area is located in the Gulf of Mexico 160 miles southwest of Lafayette. Threedimensional seismic data and some well logs were integrated and analyzed to construct a reasonable geological subsurface image. GeoFrame software from Schlumberger was used in this research. A spatial attention was given to salt diapers. Their influence on sand accumulations and hydrocarbon traps were investigated. Two Pleistocene sands accumulations (4500-ft & 8500-ft) were examine thoroughly in this research. Time and amplitude maps were produced. In addition, a wave-theoretical model that describes salt tectonic activities within the area was reconstructed in order to understand the influence of these dynamical forces on the overlaying strata.

A headteacher recruitment crisis continues in the primary education sector (Howson & Sprigate, 2011; Rhodes et al., 2008). This research offers a voice for an increasingly marginalised group and synthesises the experiences of 15 primary headteachers, including retired, experienced and new school leaders against the changing educational scenery of four decades. An extended metaphor describing a changing epistemological landscape is utilised (Pascale, 2011), including dramaturgical discourse (Goffman, 1974). The research assesses whether the lived experiences of school leaders evidence a supposed movement away from the ‘freedom’ of the ‘secret garden’ of the pre-National Curriculum era to a time of reducing freedoms for headteachers under a central panoptic gaze (Foucault 1979; Ball 2006) and then to a new ‘supported autonomy’ as suggested by ‘Education Excellence Everywhere’ (DfE, 2016). The thesis assesses the capacity of phenomenological methodology to address the research questions and distinctions are made between approaches to phenomenology. A case is made for ensuring critical rationalism within the methodology and difficulties of attaining ‘epoche’ and ‘phenomenological reduction’ are debated. Findings support the view that there have been significant changes to headship over time. Analysis of these changes does not support the concept of a linear movement from a time of freedom to a landscape defined by Panopticism. The research suggests that a new paradigmatic shift is significantly changing the nature of primary headship with new forms of executive leadership and structures for leadership progression. Recommendations call for a reduction in the frequency of change for school leaders, a simplification of the inspection grading system, provision of clearer pathways to headship and greater support for school leaders as local authority services decline and safeguarding for leaders from the growth of social media abuse. This research offers a unique insight into headship and addresses an identified gap in educational research.

Assim, objetivou com este estudo avaliar o nível tecnológico e os investimentos necessários para a produção hidropônica de hortaliças na região extremo oeste e noroeste do estado de São Paulo, através de dados obtidos via pesquisa do tipo descritiva e exploratória por meio de entrevistas com os produtores comerciais dessas regiões. O referencial teórico baseou-se em revisão de literatura a respeito da importância desse método de cultivo para a integração e a proximidade de áreas produtivas para o interior de cidades e a viabilidade embutida nesse método. A metodologia empregada baseia-se na construção de índices tecnológicos que classificam e os avaliam em padrões (A, B, C e D) os produtores de acordo com a produção segmentada em três principais componentes: Pré-plantio; Plantio e manejo; Pós-colheita e gestão e identificar alguns comportamentos e desafios enfrentados pelos produtores ao utilizar o cultivo sem o uso de solo. Também foi realizada uma análise econômica de uma empresa tomada como exemplo, da cidade de Ilha Solteira/SP, na qual foram obtidos coeficientes técnicos relativos à demanda de fatores de produção de materiais permanentes. Foram calculados os custos de produção e fez-se a avaliação da viabilidade econômica do...

The consulted literature based on a review about the importance of this method of cultivation for the integration and proximity of productive areas to the interior of cities and the viability built into this method. The methodology used is based on the construction of technological indexes that classify and evaluate them in the (A, B, C and D) the producers according to the segmented production in three main components: Pre-planting; Planting and management; Post-harvest and management and to identify some behaviors and challenges faced by the producers when using the cultivation without the use of soil. Also, an economic analysis of a company is taken as an example, of the city of Ilha Solteira / SP, were obtained technical coefficients related to the demand for factors of production of permanent materials. The production costs were calculated, and the economic feasibility of the project w... (Complete abstract click electronic access below) / Mestre

Case studies from Cuba's Urban and Peri-Urban agriculture (UPA) revolution show that urban growing can fuel locally driven production of essential foods with minimal inputs, creating unprecedented opportunities for community food sovereignty. The fact that Cuba produces 60-70% of its vegetable needs on 25% of the land shows that the barriers that UPA faces are more sociopolitical than agronomic. As an agricultural hub with an abundance of rural land within close proximity of the city, the need for UPA in Burlington, VT may not be as readily apparent. When compared to nearby small vegetable growers through the lens of a typical agronomic analysis, UPA nearly always comes out at a disadvantage. Yet community gardens and urban growers are multiplying in the small city. Research suggests this boom is owed to numerous multi-functional benefits provided by community gardens, including the potential for UPA to allow communities who may otherwise have limited agency in food choice with an opportunity to access culturally preferenced produce. However, while extensive evidence identifies the social benefits of community gardens, these results remain disparate from the economic analyses that most often find their ways into the hands of decision makers. This research proposes a valuation metric called Crop Value Index (CVI), and uses it to evaluate which crops and management techniques best take advantage of limited urban space in Burlington community gardens. This tool ranks crops by their ability to save gardeners money or profit and by their perceived cultural value by the gardener, and combines the two to identify which crops are the most successful in producing overall value. Through demonstrating the high functionality of UPA in the production of certain crops, CVI contributes to findings that indicate that UPA may be better able to serve niche community food needs than commercial growers, while simultaneously providing urban growers with food security and creating food sovereignty and food justice.
