    Facultat de FarmĂ cia, Universitat de Barcelona. Ensenyament: Grau de FarmĂ cia. Assignatura: BotĂ nica farmacĂšutica. Curs: 2014-2015. Coordinadors: Joan Simon, CĂšsar BlanchĂ© i Maria Bosch.Els materials que aquĂ­ es presenten sĂłn el recull de les fitxes botĂ niques de 128 espĂšcies presents en el JardĂ­ Ferran Soldevila de l’Edifici HistĂČric de la UB. Els treballs han estat realitzats manera individual per part dels estudiants dels grups M-3 i T-1 de l’assignatura BotĂ nica FarmacĂšutica durant els mesos de febrer a maig del curs 2014-15 com a resultat final del Projecte d’InnovaciĂł Docent «Jardins per a la salut: aprenentatge servei a BotĂ nica farmacĂšutica» (codi 2014PID-UB/054). Tots els treballs s’han dut a terme a travĂ©s de la plataforma de GoogleDocs i han estat tutoritzats pels professors de l’assignatura. L’objectiu principal de l’activitat ha estat fomentar l’aprenentatge autĂČnom i col·laboratiu en BotĂ nica farmacĂšutica. TambĂ© s’ha pretĂšs motivar els estudiants a travĂ©s del retorn de part del seu esforç a la societat a travĂ©s d’una experiĂšncia d’Aprenentatge-Servei, deixant disponible finalment el treball dels estudiants per a poder ser consultable a travĂ©s d’una Web pĂșblica amb la possibilitat de poder-ho fer in-situ en el propi jardĂ­ mitjançant codis QR amb un smartphone

    Estimating water consumption and irrigation requirements in a long-established Mediterranean rural community by remote sensing and field data

    The present study illustrates an original methodology for estimating irrigation requirements and quantifying real water consumption in a long-established Mediterranean rural community (Delta Llobregat, Barcelona, Spain), combining data from remote sensing, field mapping and in situ measurements. Because of land fragmentation and crop diversification, SPOT-5 imagery was used, given its spatial and temporal resolution and spectral attributes. Simultaneously, four flow meters were installed in two representative locations to measure water inputs and outputs every 5 min. Conveyance and irrigation efficiency were estimated for the entire irrigation community. The average conveyance efficiency was 46.8% and the classical and net irrigation efficiency reached 26.4 and 59.8%, respectively, with half of the water volume (55% or 3.2 hm3 ) returned to the river or diverted to wetlands, the maximum percentage of estimated error being about 3.4%. These results indicate an exceptionally high water loss rate due to the irrigation system (flooding), the ageing conveyance network and urban infrastructure breakdown. The applied protocol proved useful for monitoring low-efficiency irrigation systems in small communities experiencing intense urban and industrial pressures
