The rise of population in urban areas makes it ever more important to promote agriculture (UA) that is efficient terms water and nutrients. How meet the irrigation demand UA particular concern where sources are often limited. With aim determining how reduce use for while maintaining productivity reducing environmental impacts UA, this study explores agronomic performance life cycle benefits three different fertigation management practices used a rooftop greenhouse tomato crop Barcelona: 1)...
Urban agriculture (UA) is a means for cities to become more resilient in terms of food sovereignty while shortening the distance between production and consumption. However, intensive soilless UA still depends on use fertilizers, which relies depleting non-renewable resources such as phosphorous (P) causes both local global impact its application. With aim reduce impacts encourage efficient nutrients, this study assesses feasibility using struvite precipitated from an urban wastewater...
Hydroponic systems are an attractive form of urban agriculture due to their low weight load, inert substrate conditions, and overall better control plant nutrition growth. However, gaining food sovereignty cannot be at the cost increasing environmental impacts, such as eutrophication nonrenewable resource depletion, associated with phosphorus fertilizer use. Struvite, a wastewater byproduct, is potential slow-releasing P source that can serve substitute for mineral fertilizer. In this study,...
The main objective of this study is to analyze the perceived barriers and opportunities with regard implementation urban agri-green roofs (UAGR) in cities. case was conducted Barcelona, a Mediterranean compact city. World Café method used work. Five categories were discussed (social, environmental, legal/administrative, technological/architectural, economic) by interdisciplinary stakeholders. A total 129 identified. identified as follows: lack information social cohesion regarding UAGR...
Solar radiation transmissivity in greenhouses is a key property largely determined by covering materials. This study compared tomato crop yields and their environmental performance of polycarbonate rooftop greenhouse with alternative materials displaying higher solar lifetime performance. An integrated approach using experimental data structural, energy modeling was used to model average productivities. At building functional unit (per m2·year), impacts varied between -29.0% +24.0% the...
Soilless crop production is a viable way to promote vertical agriculture in urban areas, but it relies extensively on the use of mineral fertilizer. Thus, benefits fresher, local food and avoiding transportation packaging associated with import could be counteracted by an increase nutrient-rich wastewater, which contribute freshwater marine eutrophication. The present study aimed explore fertilizer substitutes soilless agriculture. Phaseolus vulgaris (common bean) was fertilized combination...
Urban agriculture systems can significantly contribute towards mitigating the impacts of complex food supply chains and increase urban sovereignty. Improving these facilities in terms nutrient management lead to better practices environmental performance. Based on a rooftop greenhouse Barcelona region, we propose cascade system where leachates tomato cycle (donor crop) are used as main irrigation source for five successive lettuce cycles (receiving crop). By determining agronomic performance...
Abstract BACKGROUND Urban agriculture contributes to meeting the growing food production demand in cities. In context of low water availability, it is important consider alternatives that are able maintain production. Through a circular economy vision, this study aimed assess use substrates made from local materials as an alternative for urban periods due supply cuts. The used were coir commercial organic substrate, vegetable compost waste and perlite standard substrate; mixture (1:1) was...
In the next 10 years, cities will house 60% of world's population, where in agro-urban frontier territories, mainly semiarid regions, problems associated with land use and water distribution arise. Therefore, a model growth that contemplates lowest resources must be proposed. The aim this study is to determine environmental impact agro-services territories regions three urban scenarios, linear circular systems. focused on Luján de Cuyo Mendoza, Argentina. Through life cycle assessment,...
El interés por el cultivo de Jatropha curcas L. ha aumentado en los últimos años producto su potencial bioenergético y efi ciencia uso del agua. La literatura con respecto a esto último es, sin embargo, contradictoria. eficiencia agua transpirada (w) sido descrita como biomasa seca (MS) / (T) = Da -1 , donde es una constante dependiente déficit presión vapor. Estos parámetros han ampliamente determinados cereales; no obstante, existe escasa especÃficamente Jatropha, ninguna...
