Street art : Mirror reflections on and meshing with urban agriculture

Street Art: Mirror Reflections on urban AgricultureThis chapter will look at the way socio-political commentary exists in street art and how it has tended in recent times to be displayed overlooking community urban gardens. The urgency with which inner suburban councils in Melbourne Australia have dedicated themselves to carving out recreational spaces is a reflection on the expectations of multi-cultural groups whose culture incorporates the growth of vegetable and fruits close to their place of residence. Street art, famous for its commentary on urban ugliness, has integrated its philosophy and aesthetics, along side notable community gardens in Melbourne. The images incorporate the aims of urban agriculture whilst often simultaneously critiquing the alienation of the urban dweller cut so relentlessly from the means of growing food and from accessing land that might produce it. Community gardens in the twenty-first century go some way to reversing a state of being in which ‘workers’ were alienated from the source of their labor and their survival. This chapter will also probe the extent to which street art in the inner laneways of Melbourne incorporate in to their designs fauna and flora. This reference to all that is organic in environments devoid of vegetation draws attention not only to that absence but also for the need to address it. This work will therefore deal with two interrelating themes: 1. Street art that complements community gardens; 2. Street art that engages with agricultural imagery and images of fauna and flora with the aim of subverting the continual growth of unregulated concrete jungles. The chapter will be informed by interviews with well known Australian street artists and will also explore the work they have done in Paris, Jamaica, London and Miami on both themes stipulated above.

Australian adults’ knowledge of Australian agriculture

Purpose – Agriculture is a major generator of wealth and employment in Australia. However, it faces a range of economic and environmental challenges which require substantial community support. The purpose of this paper is to examine Australian adults’ Australian knowledge of, and attitudes towards, Australian agriculture. Design/methodology/approach – Online questionnaire survey of 1,026 adults conducted nationwide during August 2012. Findings – Most respondents had little knowledge of even the basic aspects of the industry but they approved of farmers’ performance of their roles. Latent class analysis showed that there are two groups of consumers with low and lower levels of knowledge. The respondents’ age, rural residence and universalist values were positive predictors of agricultural knowledge. Research limitations/implications – This was a cross-sectional, quota-based survey which examined only some aspects of agriculture. However, the findings suggest that more communication with the general public about the industry is required in order to build on the positive sentiment that exists within the community. Practical implications – More education about agriculture in schools and higher education is indicated. Social implications – The poor state of knowledge of agriculture threatens the social contract upon which agricultural communities depend for survival. Originality/value – The study highlights the poor state of general knowledge about agriculture in Australia. The findings could be used as a baseline against which the efficacy of future education programmes could be assessed.

Integrated aquaculture systems approach to multi water-use in irrigated agriculture.

This study explored feasibility of an integrated agri-aquaculture systems (IAAS) approach to multiple water-use within Australian irrigated agriculture, emphasising adding value and sustainability to water resources. It focussed on development, demonstration and evaluation of a case-study of IAAS-based, open-water production of Murray cod in the Sunraysia Irrigation Region, NW Victoria.

Lifelong learning for farmers - the changing world of agriculture

Farmers must understand the intricacies of export markets, futures trading, share markets and global politics. Farmers are often living and working in isolated locations where the opportunities for professional development are limited. Yet they seem able to acquire knowledge and successfully apply it, with the result that agriculture is a growing and vigorous industry. In this paper I wish to acknowledge the unique learning environment of farmers by exploring their relationship with lifelong learning.

Agriculture, trade openness and emissions: an empirical analysis and policy options

This article investigates the impact of sectoral production allocation, energy usage patterns and trade openness on pollutant emissions in a panel consisting of high-, medium- and low-income countries. Extended STIRPAT (Stochastic Impact by Regression on Population, Affluence and Technology) and EKC (Environmental Kuznets Curve) models are conducted to systematically identify these factors driving CO2 emissions in these countries during the period 1980–2010. To this end, the studyemploys three different heterogeneous, dynamic mean group-type linear panel modelsand one nonlinear panel data estimation procedure that allows for cross-sectionaldependence. While affluence, nonrenewable energy consumption and energy intensity variables are found to drive pollutant emissions in linear models, population is also found to be a significant driver in the nonlinear model. Both service sector and agricultural value-added levels play a significant role in reducing pollution levels, whereas industrialisation increases pollution levels. Although the linear model fails totrack any significant impact of trade openness, the nonlinear model finds trade liberalisation to significantly affect emission reduction levels. All of these results suggest that economic development, and especially industrialisation strategies and environmental policies, need to be coordinated to play a greater role in emission reduction due to trade liberalisation.

Nesting biology and fungiculture of the fungus-growing ant, Mycetagroicus cerradensis: New light on the origin of higher-attine agriculture

The genus Mycetagroicus is perhaps the least known of all fungus-growing ant genera, having been first described in 2001 from museum specimens. A recent molecular phylogenetic analysis of the fungus-growing ants demonstrated that Mycetagroicus is the sister to all higher attine ants (Trachymyrmex, Sericomyrmex, Acromyrmex, Pseudoatta, and Atta), making it of extreme importance for understanding the transition between lower and higher attine agriculture. Four nests of Mycetagroicus cerradensis near Uberlandia, Minas Gerais, Brazil were excavated, and fungus chambers for one were located at a depth of 3.5 meters. Based on its lack of gongylidia (hyphal-tip swellings typical of higher attine cultivars), and a phylogenetic analysis of the ITS rDNA gene region, M. cerradensis cultivates a lower attine fungus in Clade 2 of lower attine (G3) fungi. This finding refines a previous estimate for the origin of higher attine agriculture, an event that can now be dated at approximately 21-25 mya in the ancestor of extant species of Trachymyrmex and Sericomyrmex.

Comparative procedures for the sample decomposition of rocks used in organic agriculture and the determination of Cu, Fe, Mn, and Zn by FAAS

The aim of this work was to develop an appropriate sample preparation procedure for the flame atomic absorption spectrometry determination of Cu, Fe, Mn, and, Zn in rocks used in organic agriculture as a source of macro- and micronutrients.Six different procedures were evaluated and are classified into three groups: (a) pressure digestion system with Teflon bombs, (b) conventional wet digestion in a digester heating block, and (c) closed microwave system with pressure and temperature control.Two standard reference materials and two commercial samples were analyzed. It was found that the closed microwave system required low reagent consumption, less time, and resulted in low contamination.

Work and technological innovation in organic agriculture

Organic agriculture is a sustainable cultivation ecologically, economically and socially. Several researches in organic agriculture have been made from technical perspectives, economic traits or related to ecological aspects. There are practically no investigations into the nature of the technology used in organic agriculture, especially from an ergonomic perspective. From the activity analysis, this study aimed to map the technology used in the production of organic vegetables. Properties producing organic vegetables were selected representing the State of São Paulo. It was applied an instrument (questionnaire and semi-structured interview) with their managers and it was made visual records to identify adaptations, innovations and technological demands that simultaneously minimize the workload and the difficulties in performing the tasks and increase work productivity. For some of the technological innovations a digital scanner was used to generate a virtual solid model to facilitate its redesign and virtual prototyping. The main results show that organic farmers have little technology in product form. The main innovations that enable competitive advantage or allow higher labor productivity occur in the form of processes, organization and marketing.
