PERMACULTURE AS FARMING PRACTICE AND INTERNATIONAL GRASSROOTS NETWORK: A MULTIDISCIPLINARY STUDY BY JEFFREY FERGUSON DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Crop Sciences in the Graduate College of the University of Illinois at Urbana-Champaign, 2015 Urbana, Illinois Doctoral Committee: Associate Professor Sarah Taylor Lovell, Chair Professor Michelle M. Wander Associate Professor Ashwini Chhatre Professor Thomas J. Bassett ABSTRACT Agroecology is a promising alternative to industrial agriculture, with the potential to avoid the negative social and ecological consequences of input-intensive production. Transitioning to agroecological production is, however, a complex project that requires action from all sectors of society – from producers and consumers, and from scientists and grassroots networks. Grassroots networks and movements are increasingly regarded as agents of change, with a critical role to play in agroecological transition as well as broader socio-environmental transformation. Permaculture is one such movement, with a provocative perspective on agriculture and human-environment relationships more broadly. Despite its relatively broad international distribution and high public profile, permaculture has remained relatively isolated from scientific research. This investigation helps to remedy that gap by assessing permaculture through three distinct projects. A systematic review offers a quantitative and qualitative assessment of the permaculture literature, -
English Agricultural Output 1550–1750
BRITISH ECONOMIC GROWTH, 1270-1870 Stephen Broadberry, University of Warwick, [email protected] Bruce Campbell, Queen‟s University Belfast, [email protected] Alexander Klein, University of Warwick, [email protected] Mark Overton, University of Exeter, [email protected] Bas van Leeuwen, University of Warwick, [email protected] 14 July 2010 File: BritishGDPLongRun8.doc Abstract: We provide annual estimates of GDP for England between 1270 and 1700 and for Great Britain between 1700 and 1870, constructed from the output side. The GDP data are combined with population estimates to calculate GDP per capita. We find English per capita income growth of 0.20 per cent per annum between 1270 and 1700, although growth was episodic, with the strongest growth during the Black Death crisis of the fourteenth century and in the second half of the seventeenth century. For the period 1700-1870, we find British per capita income growth of 0.48 per cent, broadly in line with the widely accepted Crafts/Harley estimates. This modest trend growth in per capita income since 1270 suggests that, working back from the present, living standards in the late medieval period were well above “bare bones subsistence”. This can be reconciled with modest levels of kilocalorie consumption per head because of the very large share of pastoral production in agriculture.

A Conceptual Framework for Incorporation of Composting in Closed-Loop Urban Controlled Environment Agriculture
sustainability Review A Conceptual Framework for Incorporation of Composting in Closed-Loop Urban Controlled Environment Agriculture Ajwal Dsouza 1,* , Gordon W. Price 2, Mike Dixon 1 and Thomas Graham 1,* 1 Controlled Environment Systems Research Facility, School of Environmental Sciences, University of Guelph, 50 Stone Road East, Guelph, ON N1G 2W1, Canada; [email protected] 2 Department of Engineering, Faculty of Agriculture, Dalhousie University, PO Box 550, Truro, NS B2N 5E3, Canada; [email protected] * Correspondence: [email protected] (A.D.); [email protected] (T.G.) Abstract: Controlled environment agriculture (CEA), specifically advanced greenhouses, plant factories, and vertical farms, has a significant role to play in the urban agri-food landscape through provision of fresh and nutritious food for urban populations. With the push towards improving sustainability of these systems, a circular or closed-loop approach for managing resources is desirable. These crop production systems generate biowaste in the form of crop and growing substrate residues, the disposal of which not only impacts the immediate environment, but also represents a loss of valuable resources. Closing the resource loop through composting of crop residues and urban biowaste is presented. Composting allows for the recovery of carbon dioxide and plant nutrients that can be reused as inputs for crop production, while also providing a mechanism for managing and valorizing biowastes. A conceptual framework for integrating carbon dioxide and nutrient recovery through composting in a CEA system is described along with potential environmental benefits over conventional inputs. Challenges involved in the recovery and reuse of each component, as well Citation: Dsouza, A.; Price, G.W.; as possible solutions, are discussed. -
Review Article Suitable Substrate for Optimal Crop Growth Under
Journal of Scientific Agriculture 2018,2: 62-65 doi: 10.25081/jsa.2018.v2.860 http://updatepublishing.com/journals/index.php/jsa ISSN: 2184-0261 R E VIEW A RTICLE SUITABLE SUBSTRATE FOR OPTIMAL CROP GROWTH UNDER PROTECTED FARMS–AN ASSESSMENT AMARESH SARKAR*, MRINMOY MAJUMDER Department of Civil Engineering, National Institute of Technology, Agartala, PIN-799046, Tripura, India ABSTRACT An attempt has been made in this paper, to review crop growing substrates for protected farms. Optimal substrate type and volume for different crops cultivar is different. Substrate selection is a critical factor for optimal production of high-quality vegetables. Crop root orientation and depth determine the type and volume of substrate required which is very important for optimal crop growth and maximum profit. Growing crops on substrates in protected skyscrapers would not only mitigate the need for more land, it produces growing space vertically. Keywords: Substrate, Nutrient solution, Controlled environment agriculture INTRODUCTION structure can also be constructed on non-cultivable soil and urban roof-tops [21]. The amount of solar radiation, Food need is increasing globally as the inhabitants are which provides the energy to evaporate moisture from the increasing. Protected farming is a popular technique for substrate and the plant, is the major factor. Other growing vegetables all seasons regardless of location and important factors include air temperature, wind speed, and climate. The most innovative technology for plants humidity level [11]. The plant canopy size and shape growing in greenhouses is growing plants in mineral influences light absorption, reflection, and the rate at substrates such as rock wool, vermiculite, perlite, zeolite, which water evaporates from the soil. -
Urban Agriculture NO
Urban agriculture NO. 155 // THEME 01 // WEEK 29 // JULY 20, 2018 THEME 01 Urban agriculture FOOD AGRICULTURE CITY We are moving to cities in a fast pace. Rapid urbanization is taking us farther away from the countryside and the sources of our food production. This leads to costly problems such as food waste and health issues. Urban agriculture can address these problems by creating integral solutions. Our observations • In 30 years’ time, more than two-thirds of the world’s population will be living in urban areas, according to a United Nations report. Today, already more than half of the world’s population live in an urban area. Rapid urbanization into cities puts serious strains on the food chain (with increasing meat consumption as the most important example of this) and municipal water supplies. • Urban health problems are growing. High intake of energy-dense food that is cheap and available anywhere and anytime, coupled with limited physical activity, leads to rising health problems, especially obesity. Citizens of lower economic classes particularly struggle to reliably access nutritious, healthy food. • Around the world, we waste approximately a third of the food produced. Although food is lost along the chain, most is lost towards the end of it: at restaurants or households. • Research shows that urban agriculture, defined as the growing of crops in cities, could produce 10% of the global output of legumes, roots and tubers, and vegetable crops or 180 million metric tons of food a year. Furthermore, this study has quantified that the benefits of urban agriculture (energy savings, climate regulation, biological control of pests, etc.) could amount to $80-160 billion annually. -
Capitalist Dynamics from Above and Below in China
Forthcoming July 2015 with the special issue "AGRARIAN CHANGE IN CONTEMPORARY CHINA" of Journal of Agrarian Change Agrarian Capitalization without Capitalism?: Capitalist Dynamics from Above and Below in China Hairong Yan and Yiyuan Chen Abstract: Cooperatives, family farms, and dragon-head enterprises are emerging as new subjects of agriculture in China and are being promoted by the Chinese government as engines of agricultural development. The current dynamics of increasing capitalization of agriculture in China has been characterized by scholar Philip Huang as ‘capitalization without proletarianization’. Through case studies, we examine the dynamics of accumulation in Chinese agriculture, as well as the government's agriculture policy shift. We argue that capitalist dynamics exist in Chinese agricultural production and they come from above and below. We also argue that Chinese government’s policy shift toward de-peasantization began in the early years of the rural reform. Keywords: capital accumulation, agrarian capitalism, agrarian populism, Chayanov, China INTRODUCTION: CONTEXT AND DEBATES Thirty some years of market reform has significantly transformed China’s agrarian society and agricultural production. The official political discourse in China disavows Chinese capitalism in general. The Chinese government avows upholding socialism and making markets play ‘a decisive role’ at the same breath (China Daily 2013). It is reported that the private sector already employs 85 per cent of the national labour force, owns 60 per cent of the enterprise capital (Lu 2013) and produced more than 60 per cent GDP in 2013 (Xinhuawang 2014). Reform is underway to open the remaining public sector for private investors. With regard to agricultural sector, the latest national policy asserts ‘socialist market economy’, but strengthens a market-determined pricing system and promotes new subjects (agents) of agriculture that include agribusiness, cooperatives and family farms. -

The suitability of LED devices for plant cultivation has turned the technology into a main component in controlled or closed plant-growing environments, experiencing an extremely fast development of horticulture LED metrics. In this context, the present study aims to provide an insight into the current global horticulture LED industry and the present features and potentialities for LEDs’ applications. An updated review of this industry has been integrated through a database compilation of 301 manufacturers and 1473 LED lighting systems for plant growth. The research identifies Europe (40%) and North America (29%) as the main regions for production. Additionally, the current LED luminaires’ lifespans show 10 and 30% losses of light output after 45,000 and 60,000 working hours on average, respectively, while the 1 vast majority of worldwide LED lighting systems present efficacy values ranging from 2 to 3 µmol J− (70%). -
