The programme was launched on the basis of the European approach to ecological agriculture. Ecological agriculture mainly concentrates on biological processes, which in the field, however, did not permit to take socioeconomic, cultural and political aspects into consideration. The concept of the programme therefore gradually changed towards agroecology, which sees the agroecosystem as the resul...

This paper describes the system of the team Orange-Deskiñ, used for the CoNLL 2017 UD Shared Task. We based our approach on an existing open source tool (BistParser), which we modified in order to produce the required output. Additionally we added a kind of pseudoprojectivisation. This was needed since some of the task’s languages have a high percentage of non-projective dependency trees. In mo...

Health professionals increasingly recognize the value of farmand garden-scale urban agriculture. Growing food and non-food crops in and near cities contributes to healthy communities by engaging residents in work and recreation that improves individual and public well-being. This article outlines the benefits of urban agriculture with regard to nutrition, food security, exercise, mental health,...

Cities are increasingly challenged in sustaining their growing populations with food. As fossil energy reserves are depleted, the sustainability of food production is highly dependent on the ability to yield more food relative to resource use. In preparing cities for peak oil, urban food systems are therefore needed that make better use of local and renewable resources, as opposed to imported a...

The main goal of the present study was to develop an ecological integrity index for littoral wetland management and conservation in semiarid Mediterranean areas that have been highly impacted by agriculture, including the selection of pressure and state indicators at landscape and wetlands scales that reflect the status, condition, and trends of wetlands ecosystems. We used a causality framewor...

This article presents a social-ecological resilience assessment and attempts to explicitly examine the impacts of urbanization on resilience, with a view to explore how to strengthen social-ecological governance of the resilience of urban ecosystems. We use a combined Grey-Fuzzy evaluation model to discuss a case study of the Su-Xi-Chang city cluster, a metropolitan area in East China, in which...

1. Abstract Urban Agriculture is an accepted practice in many cities and countries, and has attracted a broad cross-section of people across the United States to start growing food in their communities. In some cases, the motivation behind Urban Agriculture is clear, but throughout the history of Urban Agriculture in the United States there have been many reasons why urbanites have started grow...

An urban microeconomic model of households evolving in a 2D cellular automata allows to simulate the growth of a metropolitan area where land is devoted to housing, road network and agricultural/green areas. This system is self-organised: based on individualistic decisions of economic agents who compete on the land market, the model generates a metropolitan area with houses, roads, and agricult...

In the winter-spring of 2001, South Florida experienced one of the worst droughts in its recorded history. Out of a myriad of ecological concerns identified during this time, the potential for catastrophic peat fire and negative impacts to wading bird reproduction emerged as critical issues. Water managers attempted to strike a balance between the environment and protection of water supplies fo...
