The role of urban agriculture in global food security is a topic of increasing discussion. Existing research on urban and peri-urban agriculture consists largely of case studies that frequently use disparate definitions of urban and peri-urban agriculture depending on the local context and study objectives. This lack of consistency makes quantification of the extent of this practice at the glob...

Urban ecological vulnerability is measured on the basis of ecological sensitivity and resilience based on the concept analysis of vulnerability. GIS-based multicriteria decision analysis (GIS-MCDA) methods are used, supported by the spatial analysis tools of GIS, to define different levels of vulnerability for areas of the urban ecology. These areas are further classified into different types o...

Urban agriculture is becoming increasingly important in developed countries, especially terms of its economic and social benefits. If urban gardens are managed according to agroecological principles - involving the efficient sustainable use local resources inputs there many environmental benefits communities. We studied Berkeley, California, Madrid, Spain, see how agroecology practiced. Communi...

Post World War II suburban growth in Canada and the US has created concern over the long-term availability of farmland to meet food production needs. Subsequent efforts to provide legal protection to agricultural land continue to shape the development of the fringes of nearby urban areas. This paper employs the concept of “agriburbia,” suburban landscapes in which agriculture maintains a signif...

How and why is urban agriculture taken up into local food policies and sustainability plans? This paper uses a case study of urban agriculture policymaking in New York City from 2007 to 2011 to examine the power-laden operation of urban environmental governance. It explores several ‘faces of power,’ including overt authority, institutionalized ‘rules of the game,’ and hegemony. It also investig...

The paper provides an updated insight on the role that urban agriculture can play in pursuing the Millennium Development Goals and more specifically MDG 1 and 7, related to poverty reduction, food security, and environmental sustainability. Reference is made to urban agriculture in relation to the recent and important issues affecting the world economy and the environment, regarding climate cha...

A model developed to analyze the environmental impacts of aquaculture and the productivity and ecological function of integrated aquaculture/agriculture systems was evaluated using sensitivity analysis and model validation methods. The validated model was used to identify priority areas for future research in integrated aquaculture/agriculture systems and to study the flow of nitrogen in these ...
