[ca] El canvi d'un sistema alimentari basat en una economia d'estoc globalitzada a un fluxos regionals o locals pot proporcionar una nova visio en el treball de problemes d'ambit global com el canvi climatic, la transicio energetica, l'adaptacio ambiental i la provisio d'aliments en un entorn cada vegada mes urba. No obstant aixo, els estudis i informes actuals donen per fet l'espai necessari per a aquests canvis i, d'altra banda, l'estudi de paisatges culturals rurals o la nova agricultura urbana encara es basen en el nostre sistema de planificacio actual. Metode: Analisi d'una explotacio agraria real avaluant la seva implantacio territorial, necessitats i model de gestio de produccio per a utilitzar-la com a model-hipotesi per al projecte d'espai lliure agricola a la Regio Metropolitana de Barcelona (RMB). Es proposara un model d'ocupacio territorial per aplicar-lo en les zones agricoles abandonades plantejant una proposta de subministrament d'aliments per a un consum local del 100% de les ciutats de Tarragona i Reus, a partir de la qual suposar la quantitat d'habitants a les que aquestes zones tindrien el potencial d'alimentar. Finalment es plantejara una hipotesi per subministrar aliments de forma local al 50% de l'RMB. Resultats: El model de produccio es basa en les practiques de conservacio de la vegetacio que voregen les parcel·les, la implantacio de reservoris per a la fauna auxiliar i autoctona dins dels cultius i la utilitzacio de tecnologia per racionalitzar les dosis de reg segons les necessitats de els cultius. Conclusions: Cada vegada es major la pressio urbanistica sobre el camp, exposant la fragilitat de la capacitat alimentaria, cal incentivar models de produccio sostenible i locals a aplicar en els espais lliures periurbans.

[en] The change of a food system based on a globalized stock economy to one of regional or local flows can provide a new vision in the work of global problems such as climate change, energy transition, environmental adaptation and the provision of food in an increasingly urban environment. However, current studies and reports take for granted the necessary space for such changes and, on the other hand, the study of rural cultural landscapes or the new urban agriculture are still based on our current planning system. Method: Analysis of a real agrarian farm evaluating its territorial implantation, needs and production management model to use it as a model-hypothesis for the project of agricultural free space in the Metropolitan Region of Barcelona (RMB). A model of territorial occupation will be proposed to apply it in the abandoned agricultural areas, planning a proposal of food supply for a local consumption of 100% of the cities of Tarragona and Reus, from which suppose the number of inhabitants to which those areas would have the potential to feed. Finally, a hypothesis will be proposed to supply food locally to 50% of the RMB. Results: The production model is based on the conservation practices of the vegetation bordering the allotments, the implantation of reservoirs for the auxiliary and native fauna within the crops and the use of technology to rationalize the irrigation doses according to the needs of the crops. Conclusions: There is an increasing urban pressure on the countryside, exposing the fragility of food capacity, it is necessary to encourage models of sustainable production and local to apply in the peri-urban free spaces.
